US 5204897

I'll search for litigation and docket information on this patent number.

Let me run additional targeted searches on litigation/docket history for this exact number.

Let me search for the actual claim text and any recent proceedings.

US 5,204,897 — Lookup Results

Scope note / methodology caveat. I do not have a direct, authenticated connection to USPTO PatentCenter/PAIR or to the Federal Circuit's CM/ECF docket system. My searching was via general web search, which surfaced Google Patents, USPTO.report, EveryPatent, Docket Alarm and news/secondary sources. Everything below is restricted to the literal number 5,204,897. No results for similar numbers are reported. Where I could not verify something authoritatively, I say so.

1. Bibliographic data

Related commonly-owned applications named in the specification: Ser. No. 697,652 (filed May 8, 1991, "License Management System"); Ser. No. 723,456 (filed June 28, 1991, "License Document Interchange Format for License Management System"); and Ser. No. 723,457 (filed June 28, 1991, "Filters for License Management System") — all naming Wyman.

Data-quality flags (reported literally, not auto-corrected):

• One secondary source (a JP international search report) rendered the date as "US 5,204,897 A (WYMAN) 20 April 1999 (20.04.1993)" — internally contradictory and inconsistent with the patent's own face date of April 20, 1993. Treat the 1999 string as an OCR/typing error in that source, not as a second date.
• The claimed priority/continuation detail (continuation of Ser. No. 722,840, filed 1991‑06‑28, abandoned) comes from the patent's own front page as reproduced by Docket Alarm, and is consistent with the 1991‑06‑28 prior-art date shown by Google Patents.

2. Abstract (as it appears on the face of the patent)

Reproduced from a verbatim exhibit copy of the patent (Docket Alarm, Exhibit 1016 in IPR2015‑00352/00353):

A distributed computer system employs a license management method. A licensed product, upon start-up, makes a call to a license server to check on whether usage is permitted, and the license server checks a database of the licenses, called product use authorizations, that it administers. If the particular use requested is permitted, a grant is returned to the requesting user node. The product use authorization is structured to define a license management policy allowing a variety of license alternatives by values called "style", "context", "duration" and "usage requirements determination method". The license administration may be delegated by the license server to a subsection of the organization, by creating another license management facility duplicating the main facility. The license server must receive a license document (a product use authorization) from an issuer of licenses, where a license document generator is provided. A mechanism is provided for one user node to make a call to use a software product located on another user node; this is referred to as a "calling card," by which a user node obtains permission to make a procedure call to use a program on another node. A management interface allows a license manager at a server to modify the license documents in the database maintained by the server, within the restraints imposed by the license, to make delegations, assignments, etc. The license documents are maintained in a standard format referred to as a license document interchange format so the management system is portable and can be used by all adhering software vendors. A feature of the database management is the use of a filter function.

3. Plain-language overview of the independent claims

Important uncertainty statement: I was not able to retrieve the complete, verbatim claim set of 5,204,897 through the sources available to me. The full patent text in my working copy stops before the claims, and the web sources I reached show only fragments. The overview below is therefore reconstructed from (a) those fragments and (b) the specification's consistent description of the invention. Treat it as a characterization, not as a quotation of claim language.

Fragments I did obtain (verbatim from EveryPatent's reproduction):

• "21. A system according to claim 19 wherein said license document is a data arrangement specified as a product use authorization, and said product use authorization is received by said server from a license issuer."
• "22. A system according to claim 16 wherein said policy components include a termination date, and said management functions can modify said termination date to an earlier termination date."
• "29. A method according to claim 15 wherein said specified restrictive rights include a set of restrictions in style of use of a software item, said set including allocative and consumptive use."

From these fragments the claim set of 31 claims evidently contains at least: one or more independent method claims around claim 15, and at least two independent system claims at claims 16 and 19 (since 22 depends from 16 and 21 depends from 19). Claim 1 is presumably also independent, with a dependent chain following it.

Based on the specification, the likely subject matter of the independents is:

• Independent method claim (per the claim-15 family): a method of managing licensed software in a computer system in which a server maintains license documents, receives a request from a user node, and grants or denies use; and in which an administrator can, through a management interface, modify policy components — but only in the direction of making them more restrictive than the rights originally granted. Claim 29's dependent language ("allocative and consumptive use") indicates the independent claim is broad enough to cover both unit styles, with those styles recited only in the dependent claim.
• Independent system claim (per the claim-16 family): a system comprising a server with a license database holding license documents, each document containing policy components, plus management functions that let an administrator modify those components only within constraints established by the license, including (per claim 22) shortening a termination date.
• Independent system claim (per the claim-19 family): the same server/database architecture where the license document is a "product use authorization" received from a license issuer (per claim 21) — i.e., the server cannot originate a license, only receive and administer one.

The unifying inventive core, in plain terms, is the management interface itself: a set of programmatic operations (open session, close session, list licenses with a filter, register/modify objects, and cursor control over result sets) that lets a licensee's administrator load, list, modify, delegate, assign and expire licenses on a license server, while enforcing that modifications can only tighten — never loosen — the rights the issuer granted.

4. Litigation and PTAB / CAFC status

CAFC 2026 dockets for 5,204,897: none found. Searches of Federal Circuit 2026 materials and general web sources returned no 2026 Federal Circuit appeal, docket entry, or opinion involving this patent. I state this as "not found" rather than "does not exist," given the search-tool limitations noted above.

Two substantive observations that bear on the plausibility of any 2026 appeal:

1. The patent is recorded as Expired – Lifetime with an anticipated expiration of June 28, 2011. Expired patents are generally not the subject of live infringement appeals, though they can still appear in appeals of validity proceedings (e.g., IPR appeals) or in damages/royalty tails.
2. The only post-issuance proceedings I found that touch this number are ones where it serves as prior art against other patents, not as the patent-in-suit:
   • IPR2015‑00352 / ‑00353 / ‑00354 (Inter Partes Review of U.S. Pat. No. 7,774,280) — US 5,204,897 was filed as Exhibit 1016 by the Petitioner on 2014‑12‑10.
   • Application/Control No. 09/829,854 — 5,204,897 (Wyman) cited together with Christiano (5,671,412) and Duvvoori (6,021,438) in a §103 rejection.
   • Application Ser. No. 10/809,674 — cited as "US Pat. 5204897 – Filed Jul 14, 1992 – Digital Equipment Corporation."
   • Numerous foreign search reports (e.g., JP, CN, KR family members) list it as a cited reference.

Historical note (context only — not about this patent's own litigation): Digital Equipment Corporation was the plaintiff in Digital Equipment Corp. v. Intel Corp. (D. Mass., filed May 1997, No. 97‑40080) over ten unrelated microprocessor patents; that case settled in October 1997. I found no source asserting that 5,204,897 was among the asserted patents in that suit — the asserted patents were described as cache-management and instruction-processing patents, which does not match this software-licensing patent. Do not infer that 5,204,897 was litigated there.

---

5. Summary of what remains uncertain

• Claim text: I do not have verified verbatim text for the independent claims (1, 15, 16, 19, or whatever the exact set is). The claim overview above is inferred and should be confirmed against the USPTO full-text or the printed patent before being relied on.
• Assignee accuracy: the Google Patents assignee listing is expressly stated to be an unanalyzed assumption; the recorded assignments (Compaq 2002, HP 2004) are the authoritative chain I found.
• CAFC/docket completeness: with no direct PACER/CM-ECF or PatentCenter access in this session, my "none found" on 2026 Federal Circuit activity is a search result, not a certified docket check.
• Date discrepancy: the "20 April 1999" date in one JP search report is inconsistent with the patent's face date and with every other source; I have not auto-corrected it, but flag it as a source error.

I'll search for litigation involving US patent 5204897 across patent litigation databases.

Initial results show prior-art citations, not litigation. Let me search litigation-specific databases.

Let me try more targeted litigation database searches.

Bottom line

I found no evidence of litigation asserting or otherwise involving U.S. Patent No. 5,204,897 ("Management interface for license management system," Wyman, issued Apr. 20, 1993, originally assigned to Digital Equipment Corporation).

To be clear about the limits of this answer: my searches (Google/Bing-indexed web, Docket Alarm, USPTO/PTAB document repositories, Unified Patents portal pages, Justia, uspto.report, and RPX-linked materials) surfaced no district court complaint, no ITC action, no CAFC appeal, and no IPR/PGR in which the '897 patent is the challenged or asserted patent. I was unable to run a complete PACER docket query or a full Lex Machina/Docket Navigator/Unified Patents Portal litigation-caselist export, so I cannot state with 100% certainty that no such case ever existed. What I can say is that nothing in the accessible record shows one.

What my searches did return (and why it is not litigation against the '897 patent)

All of the "hits" tying a case number to 5,204,897 are cases where the patent appears as prior art / an exhibit, not as the patent-in-suit:

So if you are screening for freedom-to-operate or assertion risk on the '897 patent, the reported "cases" involving the number are examiner/petitioner prior-art citations of the Wyman disclosure, not enforcement activity.

Patent status facts relevant to the "no litigation" conclusion

• Patent: US 5,204,897 A; App. No. 07/914,040; filed Jul. 14, 1992; granted Apr. 20, 1993. It is a continuation of Ser. No. 722,840, filed Jun. 28, 1991 (priority date Jun. 28, 1991).
• Inventor: Robert M. Wyman (Kirkland, Wash.).
• Original assignee: Digital Equipment Corp.; later Compaq Information Technologies Group, L.P. (2002), then Hewlett-Packard Development Company, L.P. (2004).
• Terminal status: Google Patents records "Anticipated expiration 2011-06-28" and "Expired – Lifetime." A patent that expired in 2011 cannot support an infringement suit today, and would explain the absence of recent assertion activity.
• Family note: The '897 patent belongs to DEC's software-licensing family alongside, e.g., U.S. Pat. Nos. 4,937,863, 5,260,999 (filters in license management system), and 5,438,508. I did not attempt to enumerate every case touching this family, because you asked me to report only on the specific number 5,204,897 and to exclude similar/other numbers.

Caveats and how to confirm

• I did not obtain a PACER docket report or a full Unified Patents Portal case-list export for the '897 patent; the searches that would have done so were truncated. Treat "no known litigation" as a search result, not a certified negative.
• To close the gap, the definitive checks are: (1) PACER "Patent Case" search / Docket Navigator "Patents – Litigation" for patent number 5,204,897; (2) Unified Patents Portal case list filtered to that patent; (3) Lex Machina or RPX Insight patent-level litigation history; (4) USPTO Patent Center "Litigation" tab for the application.
• Per your strict rule, I have interpreted the identifier literally as 5,204,897 and have not rolled in results for similar numbers such as 5,260,999, 5,438,508, or 4,937,863.

Answer: No litigation involving U.S. Patent No. 5,204,897 is known or evident from the sources searched; the only case appearances of the number I found are prior-art/exhibit citations (e.g., IPR2015-00353 and IPR2015-00354, concerning U.S. Pat. No. 7,774,280), which are not litigation against the '897 patent.

I'll verify the structured data with targeted searches before writing anything.

Let me check a few more angles, including litigation-driven challenges and CBM/PGR.

Proceedings overview

Zero (0) AIA trial proceedings are on file for US 5,204,897. The structured "PTAB proceedings on file" block (USPTO Open Data Portal, most recent ingest) returns no IPR, PGR, or CBM involving this patent, and independent web searching surfaced no PTAB trial naming 5,204,897 as the challenged patent. The breakdown is therefore 0 active / 0 claims invalidated / 0 claims sustained / 0 settled / 0 institution denied. Bottom line for a defendant: there is no IPR-based invalidity ruling to borrow and no claims have been canceled — but there is also no defensive value to mine, because the patent expired on 2011-06-28 (anticipated expiration per the ODP record), roughly fourteen months before AIA trial practice began on 2012-09-16. The practical posture is not "hardened patent" and not "troll with no case" — it is a dead patent: no live PTAB exposure, and no possibility of prospective infringement.

Proceedings on file

None. No proceeding entries exist to detail. Two categories of look-alike hits are worth flagging so they are not misread as proceedings against this patent:

Not a proceeding: IPR2015-00352 / -00353 / -00354 — Apple Inc. (exhibits re U.S. Pat. No. 7,774,280)

• Type: Inter Partes Review — of a different patent (U.S. Pat. No. 7,774,280), not of 5,204,897.
• Filed: 2014-12-10 (exhibit filing date shown).
• Status: Not applicable to 5,204,897.
• Relevance: US 5,204,897 (Wyman) was submitted as prior art in these petitions (e.g., Exhibit 1016). Source: Docket Alarm — IPR2015-00353, Ex. 1016.
• Defensive value: Zero directly. It confirms only that Wyman's disclosure is treated as material § 102/§ 103 art against later license-management patents — i.e., the patent is a sword against others, not a target of PTAB attack itself.

Not a proceeding: 5,204,897 as cited art in ex parte prosecution

The patent is repeatedly cited by examiners in later applications (e.g., a § 103 rejection over Christiano in view of Duvvoori and Wyman in Application/Control No. 09/829,854, and as an "X" reference in EP 1 118 923 A1 and WO 2013/127537 A1). This is ex parte examination, not an AIA trial. PTACTS document.

---

Strategic summary

Claim status: 31 claims, all UNTESTED — none canceled, none sustained. The patent issued 1993-04-20 with 31 claims and, per the ODP record, expired 2011-06-28 with no PTAB trial ever filed. There is no FWD to cite, no claim-level disposition, and no surviving-claim list produced by any adjudicative body. Nothing here supports an argument that claims 1–31 are invalid as adjudicated — the only invalidity story is the one the statute writes for you: the patent is expired, so its term is at an end.

Estoppel landscape: empty. § 315(e)(2) estoppel requires a petitioner that reached institution; there is no petitioner and no institution, so no estoppel attaches to anyone. Every prior-art ground remains theoretically available in a civil action — but note the timing asymmetry that made this patent unattractive to PTAB petitioners in the first place: IPR became available 2012-09-16, ~14 months after the patent expired. A challenger had no reason to spend a petition on a patent whose enforceable life had already ended, and PGR was categorically unavailable because 5,204,897 is a pre-AIA patent (priority 1991-06-28; application filed 1992-07-14) that issued 1993-04-20, decades before PGR existed.

Pattern signals. No repeat-petitioner pattern (there are no petitioners). No patent-owner PTAB appeal pattern — the assignee chain (Digital Equipment → Compaq → Hewlett-Packard Development) never had a PTAB outcome to appeal. No defensive aggregator (Unified Patents or similar) appears anywhere in the chain; SIPCO/Safe-Link-style NPE campaigns do not appear either. The only echo of this patent in PTAB is as a prior-art exhibit in Apple's 2014–2015 IPR cluster against U.S. 7,774,280 — evidence of its technical significance, not of any challenge to it.

---

Recommended next steps

• If you are a defendant: the dispositive point is expiration, not PTAB. Confirm the term on the ODP/Google Patents record (US5204897A, "Anticipated expiration 2011-06-28"). Any demand citing claims 1–31 can only reach conduct within the term and within the 35 U.S.C. § 286 six-year damages lookback — all of which now lies entirely before expiration. There is no FWD to cite and quote, because none exists; do not let an adversary imply otherwise.
• On invalidity: treat the invalidity case as an ordinary civil-action challenge on the 1993-era art (e.g., the references of record: Crossley 4,780,821; Dunham 4,791,565; Hershey 4,924,378; Robert 4,937,863; plus the inventor's own DECUS May 1990 presentation listed as "Other Publications"). No § 315(e)(2) estoppel constrains any ground.
• On active proceedings: none exist, so there are no institution deadlines, no oral hearing date, and no statutorily-set one-year FWD deadline to track.
• Caveat on sourcing: the ODP block is canonical and returns zero; my web searches corroborate zero PTAB trials naming this patent. I could not verify this to absolute certainty against a PTAB E2E name/number query in this session, so if you need a belt-and-suspenders confirmation, run the patent number directly through PTAB E2E / PTACTS and CourtListener's docket search before relying on the negative in a filing. The absence of PTAB activity is a real signal here — it is explained by the patent's 2011-06-28 expiration preceding the 2012-09-16 start of AIA trials, not by the patent's strength.

I'll research the assignment chain for US 5,204,897, starting with the USPTO assignment records and corroborating sources.

Evidence limitations (read first)

I could not retrieve the underlying assignment records from USPTO Assignment Center/Patent Assignment Search for this number in this session: both assignmentcenter.uspto.gov and assignment.uspto.gov are interactive query applications, and my access here is via general web search, which does not expose their result tables. Consequently:

• Reel/frame numbers: not retrieved. I will not invent them.
• Correspondent of record (the attorney/firm that filed each recording): not retrieved. This is the field you specifically flagged as the most diagnostically useful, and I cannot populate it.
• Execution dates vs. recording dates: not separable from the source I do have (Google Patents legal events, which posts a single date per event, normally the recordation date).

What I can do is report the recorded-event chain as it appears in Google Patents' legal-events view of the authoritative full text you supplied, plus corroborating third-party evidence, and flag every field that must be closed out at the Assignment Center. I have not inferred reel/frame, correspondent, or execution dates from naming or from other HP-family patents.

Inventors

Pattern notes:

• No evidence of inventor departure or inventor-side fire-sale dynamics. Wyman is a repeat inventor across the DEC software-licensing family — the specification identifies commonly-owned applications Ser. No. 697,652 (May 8, 1991), Ser. No. 723,456 and Ser. No. 723,457 (both June 28, 1991), all naming Wyman, which issued into the DEC licensing portfolio (e.g., U.S. 4,937,863; 5,260,999; 5,438,508). Continuous filing across 1990–1992 in the same program indicates a stable in-house R&D group, not a departing-inventor scenario.
• Do not treat "WYMAN ROBERT N" as a second inventor. One European search report (cited against EP 1 118 923 A1) renders the name as "US 5 204 897 A (WYMAN ROBERT N)". This is a transcription error in that secondary source; the patent face reads Robert M. Wyman. Reported literally, not auto-corrected.
• No 2026 Federal Circuit or district court activity involving this patent was found in the earlier section of this analysis; nothing in the record indicates inventor-initiated assertion.

---

Original assignee

Digital Equipment Corporation, Maynard, Mass. (the face-of-patent assignee; source: patent front page as reproduced in the IPR2015‑00353 Exhibit 1016 copy).

• Primary line of business: minicomputer and networked computer systems — VAX hardware, VMS operating system, and the layered software/tools business. Software licensing and license administration (the subject matter here) was a first-party DEC problem: DEC sold layered products on VAX/VMS and needed a license management facility distinct from copy protection, which is exactly the framing the specification adopts ("the purpose of the license management facility is not that of enforcement, nor that of 'copy protection', but instead is merely that of license management").
• Did they ship a product embodying the claims? The specification describes the invention in terms of DEC's own environment (lm__request__allocation(), lm__query__allocation(), lm__release__allocation(), VMS/VAX platform contexts, the DECUS citation), which is consistent with the invention being practiced in DEC's License Management Facility. I state this as consistent with, not proven: the patent itself is a method/system claim set and I did not retrieve DEC product documentation tying a specific shipping release to these claims.
• Current status: dissolved as an independent entity. DEC was acquired by Compaq Computer Corporation (announced January 1998; closed June 1998). DEC's name survives only as an assignor of record — notably, the 2002‑01‑09 USPTO recording for this patent lists both Compaq Computer Corporation and Digital Equipment Corporation as assignors in the same transaction, which is the classic cleanup memorialization of a completed merger.

Assignment timeline

Recorded post-issuance events, as surfaced in Google Patents' legal-events view of the authoritative text. Reel/frame and correspondent fields are unavailable to me and are shown as such rather than guessed.

• Execution date unknown / recorded 2002‑01‑09 — Reel not retrieved / Frame not retrieved

  • Conveyance: Assignment (Google Patents event text: "ASSIGNMENT OF ASSIGNORS INTEREST (SEE DOCUMENT FOR DETAILS)")
  • Assignor: COMPAQ COMPUTER CORPORATION and DIGITAL EQUIPMENT CORPORATION
  • Assignee: COMPAQ INFORMATION TECHNOLOGIES GROUP, L.P.
  • Correspondent: not retrieved. Cannot assess recurrence.
  • Context: internal corporate reorganization / post-merger consolidation of DEC and Compaq patent holdings into the Compaq information-technology group. Not a sale to a third party; both assignors are within the same corporate family.

• Execution date unknown / recorded 2004‑01‑21 — Reel not retrieved / Frame not retrieved

  • Conveyance: Change of Name (Google Patents event text: "CHANGE OF NAME (SEE DOCUMENT FOR DETAILS)")
  • Assignor: COMPAQ INFORMATION TECHNOLOGIES GROUP, LP
  • Assignee: HEWLETT‑PACKARD DEVELOPMENT COMPANY, L.P.
  • Correspondent: not retrieved. Cannot assess recurrence.
  • Context: change of name only — no transfer of beneficial ownership. This is a paper re-recording to bring the record title into line with the entity's new legal name. Corroborating (different patent, same corporate event): a PTAB filing indexed in the IPR2025‑00414 record reproduces assignment evidence that Compaq Information Technologies Group, L.P. changed its name to Hewlett‑Packard Development Company, L.P. effective October 1, 2002, with the name change filed with the Patent Office on January 21, 2004 — the same recording date shown for this patent. Source: https://ai-lab.exparte.com/documents/ptab/uspto/none/none/2223946374/IPR2025-00414_doc_9_exparte.pdf

• Original inventor → DEC assignment (pre-issuance): Google Patents' legal-events view of this 1993 patent begins in 2002 and does not surface the founding inventor-to-corporate assignment. Such a record almost certainly exists (recorded ~1991–1992, before the 1993 grant), but I did not retrieve it, its reel/frame, or its correspondent. Treat this link as an evidence gap, not as absent.

No further recorded events. Notably, there is no assignment to any licensing-only entity, aggregator, or trust after 2004. Per Google Patents, the chain terminates at Hewlett‑Packard Development Company, L.P. (recorded 2004‑01‑21) and the patent is "Expired – Lifetime," anticipated expiration 2011‑06‑28 (the 20-year term from the 1991‑06‑28 priority/continuation filing).

Cross-references checked:

• Google Patents legal events: the two entries above (only post-issuance events listed). Consistent with the earlier bibliographic section — no contradiction.
• PTAB / IPR: US 5,204,897 appears only as prior art, never as patent-in-suit: Exhibit 1016 in IPR2015‑00352/‑00353/‑00354 (Petitioner's Dec. 10, 2014 filing; patent at issue U.S. 7,774,280), and as a §103 reference in application 09/829,854 (against Christiano 5,671,412 and Duvvoori 6,021,438). Source: https://www.docketalarm.com/cases/PTAB/IPR2015-00353/Inter_Partes_Review_of_U.S._Pat._7774280/12-10-2014-Petitioner/Exhibit-1016-US_5204897/
• Unified Patents Portal / RPX: these list the patent's assignees as Compaq Information Technologies Group / Hewlett‑Packard Development Co LP and show it in citation neighborhoods of license-management patents (e.g., alongside US 5,375,206 and US 5,438,508). I found no asserter-directory entry naming this patent.
• SEC filings (10-K / 8-K): I did not retrieve any SEC filing that itemizes this patent. Large-cap filers like Compaq and HP do not enumerate individual expired patents in their periodic reports; absence of a filing reference here is not informative either way, and I am not asserting one exists.

NPE / troll-pattern signals

Score: zero strong signals, zero weak signals. The principal requested diagnostic (correspondent recurrence, signal 3) is unretrieved, not clean.

Verdict

Defensive / non-asserting — closest applicable label, with one explicit caveat.

Justification. The recorded chain contains exactly two post-issuance links, both sourced to Google Patents' legal-events view of the authoritative text: 2002‑01‑09, an assignment of interest to Compaq Information Technologies Group, L.P. with Compaq Computer Corporation and Digital Equipment Corporation as co-assignors (merger-consolidation cleanup), and 2004‑01‑21, an express Change of Name from Compaq ITG to Hewlett‑Packard Development Company, L.P. (corroborated as effective 2002‑10‑01 by assignment evidence reproduced in the IPR2025‑00414 record). No licensing-only entity, no aggregator, and no known NPE ever appears; the patent reached its 2011‑06‑28 term expiry in the hands of a large operating company, and the earlier section of this analysis found no infringement suit naming it — the only proceedings touching the number are prior-art citations (IPR2015‑00352/‑353/‑354; §103 citation in application 09/829,854).

Caveat on the label. The strict definition of "Defensive / non-asserting" is a chain terminating at a defensive aggregator, and that is not what happened here. I am applying the label in its substantive sense — the patent is neutralized and non-asserting (expired 2011, HP-owned, never asserted) — rather than in its narrow mechanism sense. If your taxonomy requires the strict aggregator definition, treat this as "not an NPE pattern; operating-company succession, expired" and route it accordingly.

Two items I could not close, and would not report as findings:

1. Reel/frame for both recordings — not retrieved; do not cite any reel/frame for this patent until verified.
2. Correspondent of record for both recordings — not retrieved. This is the field that would either complete or refute signal 3, and it is the one field worth a direct Assignment Center pull.

Verify at: https://assignment.uspto.gov/patent/index.html (search "5204897") or https://assignmentcenter.uspto.gov/. A Patent Center "Assignment" / "Litigation" tab check on application 07/914,040 would also confirm that no third recording exists between 2004 and expiry that Google Patents has not indexed.

I'll research the prior-art citations on the face of US 5,204,897 and the examiner-cited references.

I have the front-page citations and the full claim set. Now let me research each cited reference.

Prior-Art Analysis — US 5,204,897 (Verified Citation Sweep)

Prepared: 2026-04-26 · Subject: US 5,204,897 A, Management interface for license management system (Wyman), filed 1992-07-14, continuation of Ser. No. 722,840 filed 1991-06-28, issued 1993-04-20.

Builds on earlier sections. The bibliographic, abstract, litigation and "no known litigation; prior-art-only appearances" sections above are not repeated. This section adds (i) the recovered verbatim claim set, (ii) the complete front-page citation list with per-reference § 102 mapping, and (iii) a ranked relevance list.

---

0. Two corrections / resolutions to the earlier sections

Per the "flag contradictions" rule:

1. Claim text — now recovered (was listed as "uncertain"). The earlier Patent summary stated: "I was not able to retrieve the complete, verbatim claim set." That gap is now closed. The full 31-claim set is available (EveryPatent transcription of the printed patent, cross-checked against the Docket Alarm exhibit copy). The earlier inferential claim map was correct: claim 1 independent; claim 15 independent-adjacent (29 depends from 15); claims 16 and 19 independent system claims; 22→16 and 21→19. No contradiction, only more precision.
2. Examiner name — minor transcription variance (NOT auto-corrected). The earlier section recorded "Primary Examiner Salvatore Cangialosi." The OCR of the printed face (Docket Alarm Exhibit 1016) renders it "Salvatore Giangialosi"; EveryPatent renders "Giangialosi; Salvatore." Reported literally in each source; I do not resolve which spelling is the true name.
3. Secondary-source date errors (ongoing pattern). Earlier sections flagged a "20 April 1999" typo in a JP search report. A second, independent transcription error exists: EveryPatent renders cited reference 5,023,907 as "Jun., 1971," while the Exhibit 1016 OCR renders the same reference as "6/1991," and Google Patents' citation table in US 5,790,664 pairs US 5,023,907 with 1991-06-11. Per the operating rule (prefer search results over conflicting data), I treat 1991-06-11 as ground truth and flag "Jun., 1971" as a source error.

1. Sources used and verification status

I could not open a native USPTO PatentCenter/PAIR record in this session; the patent's face data were obtained from three independent USPTO-derived/secondary renderings that agree on the citation list:

Tool-budget disclosure: my second batch of searches (intended to pull the title/abstract/filing date of each individual cited reference) was terminated by a step limit. Therefore the citation list, dates, inventor names and examiner field-of-search are verified; the subject-matter descriptions of four of the eight references (4,780,821; 4,791,565; 4,924,378; 5,109,413) are NOT verified in this session and are marked ⚠️ below. I have not filled those in from memory.

---

2. The complete citation list on the face of US 5,204,897

U.S. PATENT DOCUMENTS (as printed; class column as printed):

OTHER PUBLICATIONS (one item, the only non-patent literature cited):

Field of Search (as printed): 380/4, 123, 25 · Primary Examiner: (see §0.2) · Attorney/Agent: Arnold, White & Durkee.

Note on completeness: seven U.S. patents + one NPL item is a short list for a 1993 software patent, and it is consistent across three renderings, so I treat it as the full § 56 list as printed. It does not include the three Wyman copending applications named in the specification (Ser. Nos. 697,652; 723,456; 723,457) — those appear in the Related Cases text, not in References Cited. They are treated separately in §6.

---

3. Applicable § 102 framework (pre-AIA)

The '897 patent has an effective filing date of 1991-06-28 (continuation of Ser. No. 722,840), so pre-AIA §§ 102/103 govern. Consequences that drive the whole analysis:

• § 102(b) critical date = 1990-06-28 (one year before the parent's filing date, which the continuation inherits).
• References published on/before 1990-06-28 → § 102(b) statutory bar (no swearing behind, no Rule 131).
• References published between 1990-06-28 and 1991-06-28 → § 102(a) only (can be antedated by proof of earlier invention).
• References granted after the '897's filing date, on applications filed earlier, → § 102(e) only, and § 102(e) requires the application to be "by another." § 102(e) art is not available as a § 102(b) bar and, pre-AIA § 103(c), is restricted in § 103 combinations involving commonly owned subject matter.

---

4. Per-reference analysis

For each reference I give: full citation, dates, brief description, and which of the 31 claims it potentially anticipates. Two analytical ground rules I apply (and state explicitly, because they change the answer materially):

• Anticipation of a dependent claim requires every limitation of the claim it depends from. A reference that lacks the claim-1 "management functions … to modify … said specified restrictive rights" step cannot anticipate claim 3, 4, 5, etc., no matter how completely it discloses the request/grant mechanics.
• Therefore, for most of these references, the honest § 102 answer is "dependent claims only, and only if the independent-claim limitation is also read in" — which is why the examiner's allowance over this list is unsurprising, and why the strongest real attack vector is § 103 (§5) plus the Wyman § 102(b) self-publication (§4.8).

4.1 US 4,937,863 — Software licensing management system (Robert et al.; Digital Equipment Corp.)

• Full citation: U.S. Pat. No. 4,937,863, "Software licensing management system," inventors Robert, Chase and Schafer, assignee Digital Equipment Corporation.
• Dates: filed 1988-03-07; granted 1990-06-26 per Google Patents' citation table (search-verified) — the '897's own front page prints "Jan., 1990," and the Exhibit 1016 OCR prints "1/1990"; both renderings appear to mis-state the grant month. Class 380/4 as printed.
• Description (per the '897 specification's own characterization, which is an admission): "a central license management facility"; "maintains a database of licenses for software products"; "stores a unit value indicating the number of licensing units for each product"; a user "sends a message to the central license management facility requesting a license grant"; the facility "accesses the database to see if a license exists for this product, and, if so, whether units may be allocated to the user, depending upon the user's characteristics, such as the configuration of the platform (CPU)"; and it "sends a message to the user giving permission to proceed with activation." The '897 then states that the '863 concepts "are widely applicable, and indeed are employed in the present invention."
• Claims potentially anticipated: 3, 4, 5, 6, 7, 17, 19, 20, 21 — but only if the claim-1 / claim-16 "management functions/interface to modify policy components" limitation is supplied from elsewhere. On its own, '863 appears to disclose the request → database access → comparison → grant/refusal loop of claims 3 and 17 and the server/issuer/PUA framing of claims 4, 6, 19 and 21, but not the modification architecture that is the point of the '897 invention.
• Confidence: High on the substance (it is the parent system and the '897 admits it); High that it does not anticipate independent claims 1 or 16.
• Why it matters most anyway: a specification admission. The '897's Background concedes that '863's architecture is used in the invention. Under pre-AIA practice that is applicant-admitted prior art usable in both § 102 and § 103. See spec text: "In U.S. Pat. No. 4,937,863 … a Software Licensing Management System is disclosed …" and "indeed are employed in the present invention."

4.2 US 5,138,712 — Apparatus and method for licensing software on a network of computers (Corbin; Sun Microsystems, Inc.)

• Full citation: U.S. Pat. No. 5,138,712, "Apparatus and method for licensing software on a network of computers," inventor Corbin (as printed on the '897 face), assignee Sun Microsystems, Inc.
• Dates: filed 1989-10-02; granted 1992-08-11 (both search-verified from the Google Patents citation table in US 5,790,664, which pairs US 5,138,712 with 1989-10-02 / 1992-08-11 / Sun Microsystems / the title above).
• Statutory posture: § 102(e) only. Granted 1992-08-11, i.e., after the '897's own 1992-07-14 filing date, so it cannot be § 102(a)/(b) art; its Oct. 2, 1989 application filing date is what makes it available, and it must be "by another." (It is.)
• Description: a networked licensing apparatus in which a license server on a network administers the right of individual computers/nodes to execute licensed software, with the license-limiting determination made centrally rather than by the licensed program.
• Claims potentially anticipated: 4, 7, 16, 17, 19, 21 (and 30/31 to the extent context-set limitations are met) — again subject to the independent-claim caveat. This is the best § 102(e) candidate for the "server on a network distributes/administers license rights to nodes" architecture of claims 19 and 21 and the system framing of claim 16. Whether Corbin discloses (a) a store of license documents each carrying plural alternative sets of policy components (style/context/duration), and (b) a management interface that can modify those components only restrictively, is the decisive question and is exactly what I could not verify (see §7).
• Confidence: Medium. § 102(e) status is high-confidence; the claim-mapping is provisional pending the reference text.

---

4.3 US 5,023,907 — Network license server (Johnson et al.; Apollo Computer, Inc.)

• Full citation: U.S. Pat. No. 5,023,907, inventor Johnson et al. (as printed on the '897 face), assignee Apollo Computer, Inc., title "Network license server" (title search-verified via the Google Patents citation table in US 5,790,664, which pairs US5023907A with 1991-06-11).
• Dates: granted 1991-06-11 (search-verified). The '897's front page as rendered by EveryPatent prints "Jun., 1971" — a source error; the Exhibit 1016 OCR of the same face prints "6/1991." Treat 1991-06-11 as ground truth. Class 380/4 as printed.
• Statutory posture: § 102(a) (published after 1990-06-28 but before 1991-06-28, so antedatable) and § 102(e) on its earlier application filing date.
• Description: a license server operating on a network that issues/serves licenses for programs to be executed on network nodes — i.e., the network-licence-server architecture, contemporaneous with and closely related to the '863 system.
• Claims potentially anticipated: 4, 7, 19, 21 (server on a network; license document from an issuer authorizing node use), subject to the independent-claim caveat. Not a candidate for claims 2, 8–15, 18, 22–31 (no showing of restrictive-modification, termination-date, reservation, allocation-period, or allocative/consumptive-style features).
• Confidence: Medium-High on § 102(a)/(e) availability; Medium on mapping.

4.4 US 5,109,413 (Comerford et al.) ⚠️

• Full citation: U.S. Pat. No. 5,109,413, inventor Comerford et al. (as printed on the '897 face). Title and abstract not verified in this session.
• Dates: printed as Apr., 1992; class 380/4 as printed.
• Statutory posture: § 102(e) only (granted April 1992, after the 1991-06-28 parent filing; availability depends on its application filing date, which I did not verify).
• Description: class 380/4 is the pre-1993 "software protection / cryptographic licensing" art. Based solely on the printed class I can say only that it is software-protection art of the same class as the '863 and '907 references. I decline to characterize its disclosure further.
• Claims potentially anticipated: Cannot responsibly state. If (as its class suggests) it is an access-control/licensing scheme, its realistic candidate claims are the same architectural set as §4.3 — 4, 7, 16, 19, 21 — subject to the independent-claim caveat.
• Confidence: Low. ⚠️ Flagged for verification.

---

4.5 US 4,924,378 — Hershey et al. ⚠️

• Full citation: U.S. Pat. No. 4,924,378, inventor Hershey et al. (as printed), class 364/200 (digital data processing / program control).
• Date: May 1990 → § 102(b) (before the 1990-06-28 critical date).
• Description: not verified. Class 364/200 is the general-purpose data-processing program-control art, consistent with a software-usage/access-control or metering system.
• Claims potentially anticipated: On the printed record, only useful against the generic "maintaining by said processor a store … accessing said store" framing of claims 1/16, and only if it in fact discloses a stored authorization with policy components. Candidate set (provisional): 1, 16. Not a candidate for 2–15 or 18–31 absent verified disclosure of restrictive modification, termination-date editing, reservations, allocation periods, style alternatives, delegation/backup delegation.
• Confidence: Low. ⚠️ Flagged for verification.

---

4.6 US 4,791,565 — Dunham et al. ⚠️

• Full citation: U.S. Pat. No. 4,791,565, inventor Dunham et al. (as printed), class 364/200.
• Date: Dec. 1988 → § 102(b).
• Description: not verified. Same class as 4,780,821 and 4,924,378.
• Claims potentially anticipated: Provisional only: 1, 16 (store + access), subject to verification; nothing specific.
• Confidence: Low. ⚠️ Flagged.

---

4.7 US 4,780,821 — Crossley ⚠️

• Full citation: U.S. Pat. No. 4,780,821, inventor Crossley (as printed), class 364/200.
• Date: Oct. 1988 → § 102(b). Earliest cited reference; also the oldest, so most likely to be only generally relevant background.
• Description: not verified.
• Claims potentially anticipated: Provisional only: 1, 16 (a stored record accessed by a processor). Essentially a background/noise reference unless its disclosure is broader than its class suggests.
• Confidence: Low. ⚠️ Flagged.

4.8 Wyman, "Future Directions in Digital Distributed Software License Architecture," DECUS, May 10, 1990 — the single most relevant cited item

• Full citation: Wyman, R.M., "Future Directions in Digital Distributed Software License Architecture," oral presentation, DECUS (Digital Equipment Computer User Society), Marlboro, Mass., May 10, 1990, 18 pages (as printed under Other Publications on the face of US 5,204,897).
• Date: 1990-05-10 — before the 1990-06-28 § 102(b) critical date.
• Statutory posture: § 102(b), if the 18-page item qualifies as a "printed publication" (i.e., if it was reduced to a tangible, distributed form — conference proceedings, distributed slide set, handouts). This is the key open factual question. If it qualifies, it is a statutory bar that the inventor cannot swear behind, because pre-AIA § 102(b) contains no exception for the inventor's own publication more than one year before filing.
• Description: by the same inventor and on the same architecture (distributed Digital software licensing) as the '897 and its three copending sibling cases. An 18-page treatment of "future directions in distributed software license architecture" delivered eight months before the parent's filing is, at minimum, a strong § 103 base and a plausible § 102(b) anticipation if it discloses the license server, the product use authorization with the style/context/duration/LURDM policy components, delegation, and the management interface.
• Claims potentially anticipated: Potentially 1–31 in whole or in part — i.e., this is the only cited item with the breadth to reach the independent claims, because it plausibly describes the same architecture the '897 claims. Realistically, the claims most exposed are the architectural independent claims 1 and 16, plus 2, 4, 5, 6, 7, 8, 9, 15, 18, 22, 23, 29, 30, 31 (restrictive modification, termination date, delegation removal, context set, allocative/consumptive style) to the extent the presentation discloses them. The narrow "management-attributes" claims (10–14, 24–28: reservation, allocation period, backup delegation) are less likely to be in a 18-page "future directions" talk.
• Confidence: High that it is the most relevant cited reference and the most likely § 102(b) risk; Medium that it fully anticipates a claim (it must be read verbatim against claim 1/16).

---

4.9 Quick-reference anticipation matrix

● = plausible § 102 target · ○ = only with the independent-claim limitation supplied from another reference · — = not a candidate

Bottom line of the § 102 sweep: on the printed record, no cited reference is a clean, standalone § 102 anticipation of claim 1 or claim 16, because each lacks (or has not been shown to contain) the pivot limitation — the management functions/interface that identify a stored license authorization and modify its restrictive policy components. The two references with a genuine chance of reaching the independents are (i) the inventor's own DECUS publication (as a § 102(b) bar) and (ii) Corbin/US 5,138,712 as § 102(e) art, with '863 supplying the admitted architectural base.

---

5. Honest note on § 103 (the user asked for § 102, but the record points to § 103)

Because the cited art is architecturally complete but (apparently) missing the modification feature, the realistic attack on the independent claims is a combination:

• Claims 1, 2, 16, 18 (management function that can only make policy more restrictive): '863 (license server + database + unit allocation, admitted in the specification) + Corbin/'712 or '907 (network license server) + the Wyman DECUS publication (which, as the inventor's own forward-looking architecture talk, is the natural source for "an administrator restricts a granted license").
• Claims 8, 22 (shortening a termination date): the '897's own specification describes the "termination date" management attribute as an override "which must be earlier than specified" — i.e., the limitation is presented as an administrative convenience, which favors an obviousness characterization rather than non-obviousness.
• Claims 9, 23 (removing a delegation right): '863/'712 + the known administrator-restriction concept.
• Claims 10–14, 24–28 (reservation, allocation, allocation period, backup delegation): these are the most defensible against this particular citation list, because none of the seven cited patents is in the business of delegated multi-server license-unit administration.
• Pre-AIA § 103(c) caveat: '863 and the sibling Wyman cases are commonly owned by DEC; if any § 102(e) art were commonly owned, it could not be used in a § 103 combination. Corbin/'712 (Sun), Johnson/'907 (Apollo) and Comerford are not DEC-owned, so they are usable in combinations.

---

6. Documents that are not prior art to the '897 but are adjacent (flagged so they are not miscounted)

Listed to prevent them being mistaken for cited prior art:

1. Copending Wyman applications named in the '897 specification — Ser. No. 697,652 (filed 1991-05-08, "License Management System"); Ser. No. 723,456 (filed 1991-06-28, "License Document Interchange Format for License Management System"); Ser. No. 723,457 (filed 1991-06-28, "Filters for License Management System"). These are the parent-case family, not § 56 references. Subsequent issued patents in this family include US 5,260,999 (Filters in license management system, granted 1993-11-09) and US 5,438,508 (License document interchange format, granted 1995-08-01). Because they name the same inventor, they are not § 102(e) "by another" art; the real exposure from these is a § 102(b) double-patenting / obviousness-type double-patenting question and the shared-priority question.
2. Foreign/PCT family members of the '897 itself — WO 92/20022 (published 1992-11-12), EP 0 538 453 A (published 1993-04-28), AU 659652, AU 2015892, DE 69228350, IL 102114, IL 116271, NZ 243277. Same invention; not prior art to the '897. (Family mapping verified from the EPO search-report family annex embedded in EP 1 118 923 A1.)
3. WO 92/20021 ("License management system," published 1992-11-12, DEC) — a sibling case, appearing in later-patent citation tables, not prior art against the '897 on these dates.
4. Forward citations (the ~869 "Cited By" family in US 5,790,664 and later patents) — e.g., US 5,579,222 (Intergraph), US 5,621,796, US 5,490,411, US 5,629,980 (Xerox), US 5,375,206 (HP), US 5,845,068, US 10,437,964, US 8,898,657. These cite the '897; they do not anticipate it. Several earlier sections surfaced these; they are not § 102 art.
5. Foreign search reports in which the '897 is the X-document — the EP 1 118 923 A1 search report cites "US 5 204 897 A (WYMAN ROBERT N), 20 April 1993" as an X (novelty-destroying) document against claims 1 and 11, relying on "Abstract; Figures 1–3, 5, 7; Column 6, line 43 – Column 8, line 40; Claims 1, 4, 5." CN 1 005 077 97 C and JP 2012-133801 A, KR 100716039 B1 likewise list the '897 as a cited reference. All of these show the '897 acting as prior art against others, never the reverse. Usefully, the EPO's pinpoint citation tells us the EPO considers cols. 6:43–8:40 — the product-use-authorization / policy-components passage — to be the '897's core anticipatory disclosure, which aligns with independent claims 1, 16, 29, 31.

---

7. Ranked answer to "most relevant prior art for US 5,204,897"

If a single reference had to be named: the Wyman DECUS presentation of 1990-05-10 — not because it is the closest architecturally (that is '863), but because it is the only cited reference that is (a) dated before the § 102(b) critical date, (b) not antedatable, and (c) broad enough to plausibly disclose the management-interface subject matter that distinguishes the '897 from '863.

---

8. What I could not verify, and how to close each gap

1. Reference texts for 4,780,821, 4,791,565, 4,924,378, 5,109,413 — my verification searches were cut off by a step limit. Action: pull each patent's full PDF and read claim 1 plus the summary of the invention; these four are the only items whose descriptions I have not grounded. ⚠️
2. Application filing dates for 5,023,907, 5,109,413 and 4,937,863's exact grant date — needed to fix the § 102(a)/(e) boundaries precisely. (5,138,712 is verified: filed 1989-10-02, granted 1992-08-11.)
3. Whether the DECUS item is a "printed publication" — decisive for the § 102(b) analysis. Action: obtain the DECUS 1990 Spring Symposium proceedings/distributed materials for Marlboro, Mass., May 10, 1990, and verify the 18-page item was distributed; if it was only an oral talk with no distributed writing, § 102(b) fails and the item becomes at most a § 102(a)/(g) or § 103 issue.
4. Whether any uncited art was cited via an IDS but never printed — the '897 face shows only 7 patents + 1 NPL. Action: check the PatentCenter file wrapper (Application/Control No. 07/914,040) for IDS submissions and examiner's search notes; also check the parent, Ser. No. 722,840.
5. Printed-vs-OCR discrepancies to confirm against the paper copy: (i) grant date of 4,937,863 ("Jan., 1990" on the face vs. 1990-06-26 per Google); (ii) "Jun., 1971" for 5,023,907 (must be 1991); (iii) examiner name "Cangialosi" vs. "Giangialosi." All three should be resolved against the USPTO full-text/paper copy, and I have not auto-corrected any of them in the citation table above.
6. Confirm the citation list is complete — I have three agreeing renderings but no native PatentCenter record in this session.

One methodological caution worth stating plainly: the earlier Patent summary section correctly noted that no litigation asserting the '897 exists and that the only proceedings touching the number (IPR2015-00352/-00353/-00354) use it as Exhibit 1016 prior art against US 7,774,280. The natural next step for a validity analysis — and the only place where the '897's own cited art was actually tested adversarially — is to read the Petitioner's Exhibit 1016 in those IPRs and the Board's treatment of the Wyman reference, since the Petitioner had every incentive to characterize the '897's disclosure most broadly.

I'll pull the actual prior-art citations listed on the patent's Google Patents page before analyzing, so the combinations are grounded in the record rather than in my memory.

I now have the actual "References Cited" list from the patent's face (via the Docket Alarm exhibit copy and EveryPatent). Let me characterize those references and check how the '897 patent was treated as prior art in the IPR where it was Exhibit 1016.

Obviousness Analysis — U.S. Patent No. 5,204,897 under 35 U.S.C. § 103(a)

Patent: US 5,204,897 A, "Management interface for license management system" (Wyman; Digital Equipment Corp.; filed 1992‑07‑14 as a continuation of Ser. No. 722,840 filed 1991‑06‑28; issued 1993‑04‑20; 31 claims; expired 2011‑06‑28).
Governing law: Pre‑AIA § 103(a). The application's 1991 priority date pre‑dates the AIA, so Graham v. John Deere, KSR Int'l v. Teleflex, and pre‑AIA § 102 categories control. All § 102 date arithmetic below runs from the 1991‑06‑28 critical date.

0. Correction to the earlier-generated section (contradiction flagged)

The previously generated Patent summary stated that it could not retrieve the claim set and inferred that "one or more independent method claims [were] around claim 15" and that there were "at least two independent system claims at claims 16 and 19." That inference is incorrect, and I flag it explicitly rather than silently building on it. Working from the verbatim claim text reproduced at EveryPatent (http://www.everypatent.com/comp/pat5204897.html), the actual claim structure is:

Consequences that matter for the § 103 analysis: (i) claim 15 is not independent — it depends from claim 1, and claim 29 depends from claim 15; (ii) there is only one independent system claim (16), and claim 19 is a dependent claim reached only through 17; (iii) therefore the entire patent rises or falls on the § 103 exposure of claims 1 and 16, which are considerably broader and thinner than the earlier section implied — claim 16 in particular does not recite the "more restrictive only" limitation (that is claim 18), does not recite a server, does not recite an issuer, and does not recite remote procedure calls. Those elements live only in dependent claims.

The earlier section's factual statements about bibliographic data, the '863 relationship, the IPR2015‑00352/‑00353 exhibit history, and expiration are not contradicted by anything I found and I do not repeat them here.

1. The prior art of record on the face of the patent

Taken verbatim from the "References Cited" block of the printed patent (exhibit copy at https://www.docketalarm.com/cases/PTAB/IPR2015-00353/Inter_Partes_Review_of_U.S._Pat._7774280/docs/12-10-2014-Petitioner/Exhibit-1016-US_5204897.pdf and http://www.everypatent.com/comp/pat5204897.html):

U.S. Patent Documents

Other Publications

• Wyman, "Future Directions in Digital Distributed Software License Architecture," Oral presentation, DECUS (Digital Equipment Computer User Society), Marlboro, Mass., May 10, 1990, 18 pages.

Data-quality flags (reported literally, not auto-corrected) — carried forward from the earlier section

1. US 4,937,863 date conflict. The '897 face says "1/1990." Espacenet's bibliographic record for US4937863(A) gives 1990‑06‑26, as does RPX (https://insight.rpxcorp.com/patent/US4937863A), with a filing date of 1988‑03‑07 and priority via EP0332304 (published 1989‑09‑13). I do not resolve the conflict. Note the consequence either way: even the later 1990‑06‑26 date is 1 year and 2 days before 1991‑06‑28, so '863 remains § 102(b) art — but only by two days. If the true issuance date were later than 1990‑06‑28, '863 would drop to § 102(e) art as of its 1988‑03‑07 filing date, which would not harm its availability, because its filing date comfortably precedes the '897 priority date.
2. US 5,023,907 date error in a secondary source. EveryPatent renders this entry as "Jun., 1971." That is internally impossible (a 1971 patent cannot carry a 5,02x,xxx number) and inconsistent with the Docket Alarm exhibit OCR, which reads "6/1991." Independent records identify US 5,023,907A as Network license server, filed 1988‑09‑30, issued 1991‑06‑11, originally assigned to Apollo Computer, Inc. I treat 1991‑06‑11 as the issuance date and flag the "1971" string as a source error.
3. Reference content confidence. I have verified the disclosure content of '863 and '907 only. I have not retrieved the specifications of Crossley '821, Dunham '565, Hershey '378, Comerford '413, Corbin '712, or the 18‑page Wyman DECUS deck. Where I rely on those, I say so and label it as a hypothesis to be confirmed against the documents.

2. The strongest § 103 case starts with the applicant's own admissions

This patent is unusual because the patentee supplied most of the motivation-to-combine evidence itself, in the Background section:

"While the concepts disclosed in the U.S. Pat. No. 4,937,863 are widely applicable, and indeed are employed in the present invention, there are additional functions and alternatives that are needed in some applications."

"[i]n a manner similar to that of U.S. Pat. No. 4,937,863" (describing the license server / request-grant protocol)

"the previous practice has been to specify only the ending date, rather than also a start date as employed here."

Two legal consequences:

1. Admitted prior art. A patent's own characterization of a reference as disclosing subject matter "employed in the present invention" is a binding admission usable in a § 103 ground. This makes '863 not merely prior art but admitted prior art, and it makes the "additional functions and alternatives that are needed" language an expressly articulated problem statement — which is precisely the "articulated reasoning with rational underpinning" that KSR requires for the motivation prong.
2. Common ownership / common field. '863 is Digital Equipment Corp. property; '897 is Digital Equipment Corp. property; both are classified in the same art (software licensing, 380/4 and its successors). Combined with the same-assignee status, this satisfies the "same field of endeavor / common ownership" rationales of MPEP 2144.04(IV) and KSR.

3. What '863 actually discloses, measured against claim 1

US 4,937,863 (Robert, Chase & Schaefer) Software licensing management system, https://patentimages.storage.googleapis.com/dd/d3/a5/7db50304276d51/US4937863.pdf; EP counterpart EP0332304A3.

Verified disclosure, verbatim from '863's own summary and claims:

• License database with per‑product entries: "the license data base 11 contains a plurality of entries 20 … each containing information relating to the terms of the license for a particular licensed program 14." → the claimed "store of license authorizations for said software items."
• Termination date as a policy field: '863 claim 2: "said licensing storage means includes a plurality of fields including a licensing unit storage field … and a field identifying a termination date"; and "if the entry 20 indicates a termination date, the license management facility 10 compares the system data … with the termination date." → the claimed "restrictions in … duration of use."
• Selection-criteria-keyed allocation table: '863 claim 6: "each usage allocation table includes a plurality of entries each identifying a usage allocation value associated with a licensing usage allocation value selection criterion," and the request message carries that criterion (in the embodiment, the System Marketing Model (SMM) code of the platform). → the claimed "restrictions in context of use" and, critically, the claimed "plurality of sets of policy components … each set providing alternatives." A multiplicity of rows each assigning a different unit cost to a different environment is a plurality of simultaneously available licensing alternatives.
• Separate policy module: "a licensing policy module 15 … jointly determines whether a licensed program may be operated"; "the licensing policy module determines whether to allow the licensed program to be used in response to other licensing policy factors." → a policy-abstraction layer distinct from the enforcement layer, which is what makes post‑registration policy editing a modular, predictable addition rather than a rearchitecture.
• Request/grant/release protocol: "a GRANT LICENSE request message is generated"; "the license management facility transmits a usage approved response"; adjustments on release (claim 8). → the claimed user-request/grant loop of claims 3–5 (though '863, not '897, is the one that recites it broadly).
• Licensor-set policies: the EP0332304 abstract states the licensed program's "operation … depends upon policies established by the licensor." → a hook for claim 1's "license authorizations being received by said processor … from a license grantor external to said processor."
• Operator/logging feedback loop: '863 logs the usage-disapproved response, and states "this information may be used by a system operator." → an express textual motivation to give the operator a management facility.

The only material element of claim 1 not affirmatively disclosed by '863 is the second step: "accessing said store by said processor using management functions executed on said processor to identify a license authorization in said store, and to modify in said store one or more of said specified restrictive rights."

That single element is the entire § 103 battleground for this patent. Everything else in the independent claims is '863.

---

4. Ground 1 — Claim 1 and claim 16 obvious over '863 in view of the knowledge of a person of ordinary skill

Proposed ground: Claims 1 and 16 unpatentable under § 103(a) over US 4,937,863.

• Claim 16 is a means-plus-function claim (§ 112(f)) whose recited functions are: (a) "maintaining and accessing a store of license documents"; (b) each document containing "an indication of license policy … having plurality of sets of policy components … granting specified restrictive rights" including "restrictions in context of use and duration of use," with each set "providing different alternative[s]"; and (c) "a management interface executable on said computer for accessing said store to modify selected ones of said policy components of an identified license document." Elements (a) and (b) are '863's license data base 11, entry 20, termination-date field, and multi‑row allocation tables (claims 2, 3, 5, 6, and 13 of '863). Element (c) is the contested addition.
• Claim 1 adds nothing over claim 16 except the external-grantor element (which '863's "policies established by the licensor" addresses) and the "accessing … to identify … and to modify" step.

Motivation, articulated:

1. The patent itself states that "additional functions and alternatives are needed." Where the specification frames the administrator's inability to adjust a loaded license as the unmet need, the reason to add an administrative edit capability is supplied by the reference system's own acknowledged deficiency — not by hindsight.
2. '863 already segregates a policy module from the enforcement facility. Adding a management/administration front end to a system that already has a discrete policy layer is the classic "arrangement of old elements" with no change in their respective functions (KSR; MPEP 2144.03).
3. '863 already contemplates a human operator acting on logged license events. Configuring a database-editing interface to that operator's use is the predictable use of a known technique (general database administration) to improve a similar device in the same way.
4. Design incentive / market pressure. The '897 background itself recites the commercial demand for granular and varied license terms (single CPU vs. network vs. cluster; per‑feature licensing of spreadsheet modules; CD‑ROM delivery with only some parts licensed). A licensee-side ability to narrow a granted license creates no new engineering problem: it is strictly a reduction of an already-represented value set, which is why every dependent claim of substance (2, 8, 9, 18, 22, 23) is phrased in the restrictive-only direction.

Predicted rebuttal and its weakness: a patent owner will argue that '863 is a single-policy-system and therefore "teaches away" from a multi-alternative policy structure. The specification forecloses that argument: the applicant stated on the record that '863's concepts "are employed in the present invention." A reference cannot teach away from a use the patentee admits making of it.

5. Ground 2 — Distributed/server/RPC claims obvious over '863 + '907

Proposed ground: Claims 3‑7, 17, 19, 20 (and, by dependency, 21) unpatentable under § 103(a) over US 4,937,863 in view of US 5,023,907 (Johnson et al., Network license server, Apollo Computer; available under § 102(e) as of its 1988‑09‑30 US filing date).

• '907's title and art unit (a network license server) supply the claimed "server on a distributed network" / "user node on said network" architecture of claims 4, 7, and 19.
• The RPC framing of claims 5 and 20 ("said request is in the form of a remote procedure call, and said grant or refusal … is a return of said procedure call") was, by 1991, a notorious, standardized client/server communication idiom — the '897 specification itself treats RPC as the ordinary communication medium ("remote procedure calls are used as the communication medium for the interfaces between components of the system"), which is an admission of conventionality. Taking a known server-request/program-response protocol and expressing it as an RPC is precisely the "predictable variation" of KSR and the "obvious design choice" of MPEP 2144.04.
• Motivation: both references are directed to administering software access across networked nodes; a POSITA would combine them to centralize license administration for network-attached products, which is the very problem both references address. Expectation of success is high because neither reference requires modification of the other's operation — '907's server simply becomes the node on which '863's license management facility and data base execute.

Confidence note: I have verified '907's title, assignee, and issue/filing dates; I have not read its specification in this session. Its role as the secondary reference is asserted at the level of title/field/architecture and should be confirmed by quotation before being relied on.

---

6. Ground 3 — The termination-date and reservation claims obvious over '863 + '821/'565

Proposed ground: Claims 8, 11, 12, 22, 25, 26 (and the allocation-period/backup-delegation claims 13, 14, 27, 28 by further combination) under § 103(a) over '863 in view of one or more of US 4,780,821 (Crossley), US 4,791,565 (Dunham et al.), US 4,924,378 (Hershey et al.).

• Claim 8 / claim 22 ("policy components include a termination date, and said management functions can modify said termination date to an earlier termination date") and claim 2 / 18 (modification only to "more restrictive" rights) are, on their face, single-field edit operations on a database field that '863 already stores and already tests. Once the administrator's edit capability is supplied by Ground 1, editing the one numeric date field that the counter already consults is not an inventive act; it is the only value for which the '863 entry already contains an expiry semantic. The specification concedes as much: "the previous practice has been to specify only the ending date."
• Claim 11 / claim 25 ("a reservation of units … so that said units will not be granted to a user") is a negative allocation — i.e., setting aside a subset of the units granted value that '863's claim 1 already stores and decrements. Subtracting units from an available pool is the same operation '863 performs on every grant; doing so on an administrative rather than a request-driven basis is a trivial re-parameterization.
• Motivation: the references of record in this class—Crossley '821 (364/200), Dunham '565 (Effective Security Systems, Apparatus for controlling the use of computer software), Hershey '378 (364/200)—are all software-access-control/administration references from the same 1988‑1990 window and the same field. Under MPEP 2144.04, a POSITA addressing the administration of software access rights would look to precisely this body of art.

Confidence note (material): I have not verified the disclosures of Crossley, Dunham, or Hershey in this session. Ground 3 is therefore the weakest-grounded of the grounds and must be re-run against the actual documents before being relied on. The element-mapping logic above is independent of their content, however, because Ground 1 alone reaches the same limitations via '863's own termination-date field.

7. Ground 4 — The inventor's own § 102(b) publication

Proposed ground: Every independent and dependent claim under § 103(a), and possibly § 102(b), over Wyman, "Future Directions in Digital Distributed Software License Architecture," DECUS, May 10, 1990, 18 pages.

This reference deserves emphasis, and the earlier-generated sections did not address it:

• Its title is, on its face, directed to the architecture of distributed software licensing — the precise subject matter of claims 1 and 16.
• It is dated May 10, 1990, which is more than 13 months before the 1991‑06‑28 critical date → § 102(b) art under the "printed publication / public use" branch, assuming the DECUS presentation was publicly accessible (DECUS symposia were open user-society meetings; the earlier section's own background search confirms DECUS symposia were a public venue in which "engineers exhibited new products").
• It is authored by the named inventor of the '897 patent. A publication by the inventor more than one year before filing is § 102(b) art against the inventor; there is no grace-period exception under pre‑AIA law.

If the 18‑page deck discloses the style/context/duration/LURDM architecture (as its title strongly suggests), it is a § 102(b) single-reference anticipation ground against, at minimum, claims 1‑15 and 29, and a § 103 ground against the management-interface claims (which the deck would combine with ordinary database administration). This is the single highest-value item to pull next, and it is not available in the free-text sources I reached.

---

8. Ground 5 — The § 102(e) post-critical-date references

Proposed ground: Claims 1, 16, and dependents under § 103(a) over '863 in view of one or both of US 5,109,413 (Comerford et al.) and US 5,138,712 (Corbin), each available as § 102(e) art as of its own US filing date, with the admission-based motivation from '863.

Because both issued after 1991‑06‑28 (April 1992 and August 1992), they are not § 102(b)/§ 102(a) art and cannot be used as "prior art" in the ordinary sense; they can be used only under § 102(e) with the reference's filing date as its effective date. I flag that both are in art unit 380/4 — the same class as '863 — which makes a common-field-of-endeavor motivation readily available. I have not verified their disclosures; this ground is a placeholder, not an assertion.

---

9. Where the § 103 case is strong, and where it is weak

Strongest exposure (most likely to be held obvious):

Weakest exposure / best non-obviousness arguments available to a patent owner:

1. No claim recites the filter, cursor, session, or LDIF machinery. Filtering was separately claimed in the sibling patent US 5,260,999 and the interchange format in US 5,438,508 (both filed 1991‑06‑28 and cited against the '897 in later art, e.g. https://web.archive.org/web/20200513084927/https://patents.google.com/patent/US5790664A/en). The patent owner can therefore argue the '897 claims are directed to the administrative-interface concept, and that the '863 art has no administrative layer at all.
2. Asserted absence of a "modify licensed terms post-issuance" teaching. If, on inspection, '863 discloses only reading the license database and never writing to it by an administrator, the patent owner will press the "missing element" argument and demand the petitioner supply a real secondary reference teaching post-registration modification of license terms — not merely "databases can be edited."
3. § 112(f) indefiniteness. Claim 16's "management interface" and "means executing on said computer for maintaining and accessing a store" have no clearly corresponding structure recited, which cuts both ways: it can undermine the claim's validity, but it also makes the claim hard to map with precision.

Secondary considerations. I found no evidence of record bearing on objective indicia — no commercial success data, no licensing-due-to-the-'897 evidence, no long-felt-need testimony, no industry praise. The patent is expired (2011‑06‑28), so no injunction-related or ongoing-royalty record exists to draw from. Absent such evidence, the Graham secondary factors do not currently weigh against the prima facie case. I say this as "not found," not as a certified negative.

Procedural posture. No IPR, PGR, CBM, or ex parte reexamination of the '897 patent itself appears in the accessible record. Its documented post-issuance appearances are as prior art against later patents: it was Petitioner Apple's Exhibit 1016 in IPR2015‑00352/‑00353/‑00354, filed 2014‑12‑10, concerning US 7,774,280 (ContentGuard Holdings) — and the Board's 2015‑06‑25 decision denying institution in IPR2015‑00353 turned on whether England disclosed a "repository" with "communications integrity," not on the '897 disclosure (https://natlawreview.com/article/apple-inc-v-contentguard-holdings-inc-denying-institution-where-claim-interpretation). The Wyman work also appears among the references considered in the CBM2015‑00040 final decision on the '280 patent (https://ipwatchdog.com/wp-content/uploads/2018/07/ContentGuard-final-decision.pdf). That history confirms the disclosure's significance as a foundational reference in the field, and it is consistent with — though it does not prove — the conclusion that the '897 claims sat close to the art that already existed in 1990‑1991.

---

10. Bottom line

• The § 103 case against claims 1 and 16 of US 5,204,897 is, on the face of the patent's own cited references, strong: US 4,937,863 discloses a license database, unit pools, a termination-date "duration" field, a selection-criteria-keyed allocation table constituting multiple alternative policy sets, a separate policy module, and an operator feedback loop; and the '897 specification admits that '863's concepts "are employed in the present invention" while stating that "additional functions and alternatives are needed." That admission supplies the articulated motivation for the one remaining element — an administrative interface that edits the policy components in place.
• The strongest single-reference/commercial-relation combination is '863 (primary) + '907 (network license server), with '821/'565/'378 available for the pure-administration and reservation claims and Comerford '413 / Corbin '712 available only as § 102(e) art.
• The highest-value unverified item is the Wyman DECUS presentation of 1990‑05‑10, which is § 102(b) art by the inventor himself and, on its title alone, plausibly discloses the core architecture.
• I must be explicit about the limits of this analysis: I verified the disclosure content only of '863 and (at the bibliographic/title level) '907. I did not retrieve Crossley '821, Dunham '565, Hershey '378, Comerford '413, Corbin '712, or the DECUS deck. Grounds 3‑5 are therefore analytically framed but not evidence‑complete, and should not be relied on as demonstrated until those documents are pulled. This is a technical obviousness assessment, not a legal opinion or a validity determination, and no § 103 challenge to the '897 patent is known to have been adjudicated.
