US 5713075

I'll search for authoritative information on US patent 5713075, including any 2026 CAFC activity.

Let me check for the issued claims text and any litigation/CAFC activity.

Let me retrieve the issued claims from a patent text source.

Summary: US Patent 5,713,075

Important caveat up front: I did not find any 2026 CAFC docket, appeal, IPR, or district-court activity tied to patent number 5,713,075. Your instruction was to search USPTO and CAFC 2026 dockets — my searches returned nothing on point, and I will not fabricate a docket. One apparent "hit" (a "5713075" number appearing in EPO search-report annexes) is Japanese patent JP 5713075 B2, an unrelated Japanese grant and a false-positive collision — I am reporting it literally, not as this patent.

Also note: the authoritative full text you supplied is truncated (it ends mid-sentence at "add an ACU to"), so I do not have the literal issued claim language or the exact claim count in front of me. My claim overview below is therefore derived from the specification's "Summary of the Invention" and object statements, and I flag it as such rather than quoting claim text.

Bibliographic data (from Google Patents, fetched 2026-09-26)

Assignment chain (as listed): AMSC Subsidiary Corp (original) → Motient Services Inc. (2000-12-13, change of name) → Mobile Satellite Ventures LP (2002-04-05) → ATC Technologies, LLC (2005-06-17) → security interest to The Bank of New York (2006-04-10) → release by secured party to ATC Technologies, LLC / LightSquared (2010-10-07).

Family / continuations: US 5,713,075 is the parent of US 08/931,622 (filed 1997-09-16 → issued as US 6,272,341 B1), which in turn is a parent of US 09/007,172 (filed 1998-01-14 → US 6,185,409 B1, continuation-in-part and itself a continuation of the 08/931,622 case), and of US 09/918,550 (→ US 6,636,721 B2). The '409 patent's front page literally recites "which is a continuation of application No. 08/601,749, filed on Feb. 15, 1996, now Pat. No. 5,713,075." That is a hard, document-grounded confirmation of the number, dates, and inventorship.

Abstract (as given for the closely related disclosure)

The abstract text on the '409 front page describes the same subject matter: "A mobile satellite system includes at least one satellite and at least one network engineering/systems engineering (NE/SE) system. The NE/SE system performs at least one of the processes of comparing expected traffic loads with capability and availability of space and ground resources in the mobile satellite system; formulating tactical plans to maximize available resources of the at least one satellite, and producing frequency plans for different geographical regions; performing the processes of defining contingency plans for failure situations... configuring the mobile satellite system including logical resources and physical components; and configuring communication paths to external organizations operatively connected to the mobile satellite system."

I want to be careful: that is the '409 abstract, not a verbatim transcription of the '075 abstract, though the two are the same family and same specification. The '075's own front-page abstract was not visible in the text I retrieved, so treat the wording above as representative-but-not-quoted.

Plain-language overview of the independent claims

Because I could not retrieve the literal claim set of the '075 patent, the following is a functional overview based on the specification's summary and object statements, and I label it as such:

1. System claim — mobile satellite system with an NE/SE subsystem. A geostationary mobile satellite network (satellites, NOC, NCC with Group Controllers, Feederlink Earth Stations, Mobile Earth Terminals) plus a distinct Network Engineering / Systems Engineering (NE/SE) system that:

• contrasts expected traffic loads against the capability and availability of space and ground resources;
• formulates tactical plans to maximize the available satellite resources;
• produces frequency plans for different geographic regions and defines circuit pools for different groups of Mobile Terminal users;
• performs configuration management of the network's logical resources and physical components (including cellular switches) so capacity can be expanded for traffic growth while supporting new features/services;
• configures communication paths to external organizations (e.g., CMIS, marketing, bulletin-board/roaming services, PSTN agencies); and
• tracks the logistics of network additions via generation of work orders.

2. Method claim — method of engineering the mobile satellite system. The same steps recast as method acts: comparing expected traffic loads with resource capability/availability; formulating tactical plans; producing frequency plans and defining circuit pools; configuring logical resources and physical components; configuring external-organization communication paths; and tracking network additions via work orders — including collecting and reporting traffic and performance data for long-term planning.

Both independent claims thus sit on the management/provisioning side rather than on the air-interface signaling: the novel subject matter is the engineering and provisioning tool (rule-based provisioning, "working configuration" commit, attribute defaulting via Last Used vs. Template Value, frequency-plan overlap checks, power balancing across Satellite Payload → SBG → Beam, and NOC database upload/reconciliation) described at length in the specification.

Litigation / 2026 CAFC status

• No 2026 Federal Circuit docket, appeal, or IPR proceeding on 5,713,075 was found. The IPR/publication material my searches surfaced concerned other patents (e.g., claims of a '073 and a '023 patent, and the Spero v. Mercedes-Benz '029 patent appeal, Fed. Cir. No. 2025-1306) and is not about the '075 patent.
• The only recurring appearance of the string "5713075" in third-party documents is the unrelated Japanese patent JP 5713075 B2 — a literal identifier, not an alias for this US patent.

Confidence / uncertainty statement

• High confidence: patent number, title, application number 08/601,749, filing date 1996-02-15, priority 1995-11-30, issue date 1998-01-27, inventors Threadgill and Lin, original assignee AMSC Subsidiary Corporation, current assignee ATC Technologies, LLC, and the expired status — corroborated both by the supplied Google Patents text and by the '409/'341 family front pages.
• Not authoritative / flagged: the verbatim claim language and exact number of claims of the '075 patent. The supplied full text omits the claims section, and I could not retrieve it in searches. If you need claim charts or literal claim quotes, I'd need the issued-claims text (e.g., the '075 patent PDF claims column).

I'll research litigation involving US Patent 5,713,075.

Let me search more specifically on litigation databases.

Answer: No litigation involving U.S. Patent No. 5,713,075 was identified

Bottom line: I could not confirm any district court litigation, Federal Circuit appeal, ITC investigation, or PTAB proceeding involving U.S. Patent No. 5,713,075. I am stating this as "not found," not as "does not exist." I was unable to complete a verified negative check against the authoritative litigation databases (see caveat below), and I will not invent parties, case numbers, or docket entries to fill that gap.

What I searched

Per your instructions, I did not auto-correct or substitute any similar number (e.g., I did not treat the Japanese JP 5713075 B2, an unrelated permanent-magnet rotor patent owned by Daikin Industries, as the asserted U.S. patent, and I did not confuse U.S. 5,713,075 with any other "5,71x,xxx" or "5,713,xxx" patent appearing in the results).

Context on ownership (relevant to where litigation would likely be found)

From the patent's own front-page record on Google Patents, the chain of title is:

• Original assignee: AMSC Subsidiary Corp (assignment recorded 1996-02-15; inventors Shih Chao Lin and Michael E. Threadgill)
• 1998-01-27: Patent granted
• 2000-12-13: Change of name to Motient Services Inc.
• 2002-04-05: Assignment to Mobile Satellite Ventures LP
• 2005-06-17: Assignment to ATC Technologies, LLC
• 2006-04-10: Security agreement to The Bank of New York
• 2010-10-07: Release by secured party (The Bank of New York Mellon) with ATC Technologies, LLC, LightSquared Finance Co., and LightSquared LP
• Current listed assignee: ATC Technologies LLC
• Legal status: Expired – Fee Related; anticipated expiration 2016-02-15

The practical significance: any enforcement activity would most plausibly have been brought by ATC Technologies, LLC (or its predecessors Motient / Mobile Satellite Ventures) during roughly 2005–2016. I recall that ATC Technologies/related LightSquared-family entities were litigious in that period (e.g., assertions over satellite-terrestrial "ancillary terrestrial component" technology), but I cannot attribute any specific case to the '075 patent and I am not going to assert a recollection as fact. This is exactly the kind of inference that requires docket-level confirmation.

Known litigation

None identified. I found no plaintiff, defendant, jurisdiction, case number, filing date, or outcome to report for U.S. Patent No. 5,713,075.

Recommended verification steps (to close this out properly)

Because "no results found" in a general web index is not the same as "no litigation exists," the following should be checked directly against primary sources before relying on this answer:

1. Unified Patents litigation portal — https://portal.unifiedpatents.com/litigation/caselist?patents=5713075 (patent-number filter).
2. Unified Patents PTAB portal — https://portal.unifiedpatents.com/ptab/caselist?patents=5713075 (for IPR/PGR/CBM challenges).
3. PACER / CourtListener RECAP — search the patent number in the full-text docket field; note CourtListener's patent docket search and the storage.courtlistener.com/recap/ corpus.
4. USPTO Patent Center / Patent Assignment Search — https://patentcenter.uspto.gov and the USPTO Assignment database, to confirm the ATC Technologies/LightSquared chain and identify any assignments recorded in connection with a settlement or license.
5. USPTO PTAB API / PTAB Center — https://ptacts.uspto.gov (searchable by patent number).
6. Federal Circuit docket — https://cafc.uscourts.gov / the court's daily dispositions, filtered by the patent number, to catch any appeal.

If a search on the patent's own Google Patents page is performed, the "Similar Documents," "Cited By," and any litigation tab should also be reviewed — third-party aggregators such as Docket Alarm index these under the patent number.

Confidence statement: I have low-to-moderate confidence that no litigation exists. I have high confidence that my searches did not surface any, and zero confidence in any specific case details, which is why none are provided. Do not treat the absence of results above as a legal conclusion that the patent has never been asserted.

I'll start by verifying the structured ODP data against public sources.

PTAB Activity Report — US 5,713,075

Patent: Network engineering/systems engineering system for mobile satellite communication system
App. No.: 08/601,749 · Filed: 1996-02-15 · Granted: 1998-01-27 · Priority: 1995-11-30
Original assignee: AMSC Subsidiary Corp. · Current assignee of record: ATC Technologies LLC
Record status (Google Patents): Expired – Fee Related; anticipated expiration 2016-02-15

Proceedings overview

Zero AIA trial proceedings are on file for US 5,713,075 — the USPTO Open Data Portal structured block returns no IPR, PGR, or CBM petitions, and my independent searches (patent number + "IPR," petitioner/patent-owner queries, PTAB E2E-style queries) surfaced no proceeding numbers, institution decisions, Final Written Decisions, terminations, or Federal Circuit appeals. Breakdown: 0 active / 0 claims invalidated / 0 claims sustained / 0 settled / 0 institution denials.

Bottom-line defensive posture: This is not a hardened patent — it is an untested and expired one. The absence of PTAB activity is not because the claims survived scrutiny; it is because no one ever chose to spend the filing fee. Combined with the face-of-the-record expiration date of 2016-02-15, any demand letter asserting this patent today is operating on a portfolio whose term has already run, and there is no adverse PTAB record that a defendant needs to work around — nor any issued estoppel that limits the prior-art case you can build in district court.

Proceedings detail

No proceeding entries can be generated. The instructions were to source the list from the canonical structured block and not to invent proceeding numbers; that block is empty, and corroborating searches were also empty. I will not manufacture an IPR number, panel, or FWD verdict for this patent.

Caveats on the "no activity" finding

Strategic summary

Claim status: all claims UNTESTED — none canceled, none sustained. No AIA tribunal has ever construed a single claim term of US 5,713,075. There is no FWD to quote, no claim-level disposition to cite, and therefore no "claim 1 is dead" argument available to a defendant. Any prior-art or § 112 attack you want to make has to be built from scratch in whatever forum you are in.

Estoppel landscape: no § 315(e)(2) estoppel attaches to anyone. Because no petitioner ever filed, there is no petitioner-side bar on grounds "raised or reasonably could have been raised." Conversely, there is no patent-owner-favorable PTAB record to defer to. Two practical consequences worth flagging to a client: (1) the entire prior-art universe — including printed publications, on-sale activity, and system prior art from the 1992–1995 AMSC/MSAT development period — remains fully available in district court; (2) if you file an IPR, you must clear the § 315(b) one-year bar (measured from service of a complaint alleging infringement) and you will then be estopped on grounds you raised or reasonably could have raised, so a court-first invalidity theory and a PTAB theory should be coordinated rather than duplicated.

Pattern signals: none. No repeat petitioner, because there is no petitioner. No PTAB appeals by the patent owner, because there is no adverse decision. No indication anywhere in the record of a defensive aggregator (Unified Patents, RPX, Open Invention Network) in the chain of title — the reassignment history is a straight corporate chain: AMSC Subsidiary Corp. → Motient Services Inc. (2000-12-13, name change) → Mobile Satellite Ventures LP (2002-04-05) → ATC Technologies, LLC (2005-06-17), with the Bank of New York security interest (2006-04-10) released to ATC Technologies, LLC / LightSquared Finance Co. / LightSquared LP (2010-10-07). Note the LightSquared-era chain: ATC Technologies is affiliated with the LightSquared / Ligado lineage, which materially affects who would have standing to assert this patent and what a defendant's licensing-counterparty risk looks like.

One asset-side observation worth raising with the client: this patent sits at the head of a family. The record shows continuations/divisionals claiming priority back through this filing — US 6,272,341 B1 (from App. 08/931,622, priority claim 1997-09-16), US 6,185,409 B1 (from App. 09/007,172, priority claim 1998-01-14), CA 2,216,672 C, and US 6,636,721 B2 (from App. 09/918,550, priority claim 2001-08-01). A demand letter citing 5,713,075 may be a pointer at the family rather than the family's actual enforcement vehicle. Ask the asserting party to identify every patent in the family it contends is infringed, and check PTAB/litigation history on the continuations before assuming the whole family is clean.

Recommended next steps

If you are a defendant receiving a demand or complaint citing US 5,713,075:

1. Run the expiration defense first — it is nearly dispositive on damages. The record shows anticipated expiration 2016-02-15 (20 years from the 1996-02-15 filing, with no apparent patent term adjustment). Confirm this in USPTO Patent Center (https://patentcenter.uspto.gov) and review maintenance-fee payment history. If the patent expired 2016-02-15, then as of today (2026-09-28) the § 286 six-year damages lookback reaches back only to 2020-09-28 — entirely after expiration. Infringement liability does not accrue for practicing an expired claim. Push the asserting party to identify the pre-2016-02-15 acts and damages theory it actually relies on, or explain why there is one.
2. Demand the claim chart and the asserted claims. Since no tribunal has ever construed these claims, expect the patent owner to argue broad scope. The specification is dense and functional (provisioning rules, PCT/AD attribute constraints, power-balancing algorithms, work-order generation), which creates real § 112(b) indefiniteness and § 112(a) written-description/enablement exposure on any claim recited at the level of a system function — but that argument is untested and must be developed, not assumed.
3. Do not look for a PTAB shortcut. There is none. You cannot cite an FWD, invoke issue preclusion, or argue the patent owner is bound by a prior PTAB construction. Verify the null result yourself at PTAB E2E (https://ptab.uspto.gov) and the PTAB Decisions database (https://developer.uspto.gov/ptab-web/#/search/decisions) before representing to a court or client that no proceedings exist.
4. Verify non-AIA proceedings and litigation history separately. My searches could not confirm or exclude ex parte reexamination or prior district-court invalidity judgments. Check Patent Public Search for reexamination certificates on both this patent and its continuations, and pull asserted-patent histories for the family via CourtListener / RECAP (https://www.courtlistener.com) and the ATC Technologies / Mobile Satellite Ventures / LightSquared entity chain.
5. If you file an IPR, calendar the § 315(b) bar immediately. One year from service of a complaint alleging infringement, without exception for settlement or co-defendants. The statutory trial deadline is one year from institution, so institution timing drives your entire invalidity schedule — and note that because the patent is expired, any IPR you file will be adjudicated without the patent owner having an amendment option of practical value (claim amendments cannot extend an expired term).

If no PTAB activity exists — stated plainly: it does not. The absence is, in this specific case, a weak signal in the patent owner's favor (no published PTAB finding that the claims are unpatentable) and a strong signal against it (an expired, never-asserted-in-IPR patent is not a validated asset). The reflexive assumption that "well-asserted patents eventually attract IPRs" does not rescue this patent: it expired before the IPR era matured. Do not treat the lack of PTAB history as evidence of claim strength.

I'll verify the ownership record against live sources before writing anything down.

Ownership Record Reconstruction — US 5,713,075

Patent: US 5,713,075 A — "Network engineering/systems engineering system for mobile satellite communication system"
App. No.: 08/601,749 · Filed: 1996-02-15 · Priority: 1995-11-30 · Granted: 1998-01-27
Status: Expired — Fee Related (Google Patents legal events); anticipated expiration recorded 2016-02-15

Data limitation — read before the timeline. I could not open the USPTO Assignment Center record set directly (the Assignment Center UI/API is not reachable via the search surfaces available to me), and no search result returned the reel/frame numbers or correspondent-of-record fields for this patent's recordings. The events below are reconstructed from the Google Patents legal-events tab (which is derived from the same USPTO assignment records) and confirmed against FCC filings, SEC/bankruptcy filings, and the corporate history of the AMSC→Motient→MSV→SkyTerra→LightSquared→Ligado lineage. I have written "not retrieved" rather than inventing reel/frame or correspondent data. Verify at https://assignmentcenter.uspto.gov/ or https://assignment.uspto.gov/patent/index.html by searching patent number 5713075.

Inventors

Both inventors appear as assignors on the recording made at/around filing, which is direct evidence they were AMSC personnel assigning to their employer under obligation — not independent inventors later bought out. The same inventor pair recurs across sibling AMSC/MSAT filings of the same period (e.g., US 6,058,307 lists "Threadgill et al." as prior art; several Motient-era patents share this pair), which is consistent with an in-house engineering team rather than a one-off inventor group.

Departure pattern: Not determinable from the records I could retrieve. There is no evidence in the assignment record of inventors retaining or reacquiring rights, and no indication of a within-12-month departure followed by a portfolio sale. The relevant corporate discontinuity here was not inventor flight — it was the assignee's own 2000 name change and subsequent spin-off. I mark this no adverse pattern found / not independently verifiable.

Original assignee

AMSC Subsidiary Corporation, Reston, Virginia (restated in the printed patent as "AMSC Subsidiary Corporation, Reston, Va.").

• Line of business: Satellite communications. Parent American Mobile Satellite Corporation (founded 1988) operated the MSAT geostationary L-band mobile satellite service and built the Communications Ground Segment (NOC, NCCs, FESs, METs, RMS, STS) that this patent provisions and manages. It later acquired ARDIS and ran terrestrial data networks.
• Product embodying the claims: Yes — the patented subject matter is the NE/SE provisioning and configuration tool for the AMSC/MSAT ground segment itself (see the FIG. 16 architecture and FIG. 18–36 process descriptions in the specification). The patent describes the operator's internal engineering system rather than a sold product, which is typical of a carrier's OSS/BSS patent.
• Current status: No longer exists as a standalone entity. Corporate succession: AMSC → Motient Corporation (name change, April 2000) → Mobile Satellite Ventures LP (satellite operations spun off with TMI Communications, 2001–2002) → SkyTerra (Dec 2008) → LightSquared (2010) → bankrupt (2012–2015) → Ligado Networks. The original assignee's downstream successor entered Chapter 11 (see signal 6).

All entries are recorded (not necessarily executed) on the dates shown, per Google Patents legal events. Reel/frame and correspondent fields were not retrievable — stated explicitly per entry rather than fabricated.

• 1996-02-15 (recorded) — Reel/Frame: not retrieved

  • Conveyance: Assignment (assignment of inventors' interest)
  • Assignor: Shih Chao Lin; Michael E. Threadgill
  • Assignee: AMSC Subsidiary Corporation
  • Correspondent: not retrieved

No further assignment is recorded. In particular:

• There is no recorded assignment to Ligado Networks and no recorded assignment out of the LightSquared Chapter 11 estate for this patent.
• There is no recorded assignment to any licensing LLC, IP holding entity, or known NPE — not on this patent, and not on its siblings US 6,272,341 B1, US 6,185,409 B1, US 6,636,721 B2, or CA 2,216,672 C (these are priority links in the family, not assignments).
• Google Patents shows current assignee: ATC Technologies, LLC (which is also the listed recent owner on the Canadian CIPO security-agreement register for the related ATC portfolio).
• The 2016-02-15 entry is a term expiry, not an assignment.

NPE / troll-pattern signals

1. Shell-entity transfer — not present. Every recorded link moves between named operating telecom entities inside one continuous corporate lineage (AMSC Subsidiary Corporation → Motient Services Inc. → Mobile Satellite Ventures LP → ATC Technologies, LLC). No assignee carries an "IP / Patents / Licensing / Holdings / Ventures" suffix deployed as a licensing vehicle, and MSV LP's own name is a satellite operating company (MSV was the FCC licensee and the first company authorized to deploy Ancillary Terrestrial Component technology). The one "LLC" in the chain, ATC Technologies, LLC, is the FCC-license/technology holding entity that appears as a co-debtor in the LightSquared Chapter 11 — i.e., a debtor, not a shell built for assertion.

2. Known asserter in the chain — not present. None of the recorded assignors or assignees matches any entity on the public NPE lists named in the brief — not Acacia, Marathon Patent Group, Intellectual Ventures, IPNav, Wi-LAN, Mosaid/Conversant, Vringo, Pendrell, Innovatio, MPHJ, Lumen View, Round Rock, Document Generation Corp, or Spangenberg-controlled entities. ATC Technologies, LLC is an operating-license holding affiliate of LightSquared/Ligado, not a high-frequency plaintiff, and I found no infringement suit naming US 5,713,075.

3. Repeat correspondent across the chain — unclear / not verifiable. The correspondent of record is the single most diagnostic field for this question and it was not retrievable for any of the six recordings. I will not characterize this as present or absent. If you can export the reel/frame list from Assignment Center, the specific test is: does one attorney or recording firm appear on the 2000 change-of-name, the 2002 Motient→MSV assignment, the 2005 MSV→ATC assignment, and the 2006/2010 security agreement and release? Because these are all intra-group corporate transactions, a single repeat correspondent here would most likely indicate one outside corporate counsel handling the SkyTerra/MSV corporate suite, which is a weak signal at best and not probative of NPE activity. Do not treat recurrence in this chain as an NPE tell without the compensating evidence in signal 1, which is absent.

4. Cascading transfers — not present. The chain shows three recorded transfers over a nine-year span (2000-12-13, 2002-04-05, 2005-06-17), not multiple consecutive assignments through chained LLCs inside 24 months. The 2000 event is a name change, and the 2002 and 2005 events are spin-off and intra-group re-titling. No shared registered-agent address or single-purpose LLC pattern appears.

5. Pre-litigation transfer — not present / unclear. The last ownership-affecting recording is 2005-06-17 (MSV → ATC Technologies, LLC), roughly seven years before the May 2012 LightSquared petition date and long before any assertion activity. I found no infringement suit naming US 5,713,075, so there is no pre-suit transfer to anchor this signal. The litigation this patent family appears in is regulatory and bankruptcy-related (FCC IB Docket No. 11-109 and 12-340, Ligado's Court of Federal Claims takings case, and the Inmarsat contract disputes), not patent assertion.

6. Bankruptcy fire-sale — present at entity level; not present at patent level. The recorded assignee of record, ATC Technologies, LLC, is expressly listed as a debtor in In re LightSquared, Inc., Case No. 12-12080 (SCC) (Bankr. S.D.N.Y., petition date 2012-05-14), alongside LightSquared LP, LightSquared Finance Co., and others, under the Joint Chapter 11 Plan proposed 2013-07-23 (White & Case LLP for the Ad Hoc Secured Group of LightSquared LP Lenders). The LP Assets were subject to a court-supervised auction and sale process. However, I found no assignment recorded for US 5,713,075 out of that estate, and a second Ligado restructuring followed in 2025. The patent itself expired 2016-02-15 rather than being sold to an assertion vehicle, so the bankruptcy is a corporate-context fact, not evidence of a patent fire-sale into an NPE.

7. Privateering — not present. No operating company transferred this patent to an NPE that then asserted on its behalf. The transfers are all self-dealing corporate successions within the same group, and the terminal entity is the operator/licensee itself, not a licensing proxy.

8. Defensive aggregator — not present. The chain does not terminate at RPX, AST, LOT Network, Unified Patents, or OIN. There is no neutralization event; the patent simply expired inside the successor operating company.

Verdict

Insufficient data.

I select this in the sense of "no NPE evidence established" rather than "no records exist" — the record set does exist and the chain is fully traceable. Every recorded link (1996-02-15 inventor assignment → 2000-12-13 change of name to Motient Services Inc. → 2002-04-05 to Mobile Satellite Ventures LP → 2005-06-17 to ATC Technologies, LLC → 2006-04-10 Bank of New York security agreement → 2010-10-07 release) is an intra-group corporate succession, spin-off, or securitization within a single satellite operating lineage; zero of the eight NPE signals is affirmatively present at the patent level, and no assertion suit naming US 5,713,075 exists. The one genuine distress event — ATC Technologies, LLC's inclusion as a debtor in In re LightSquared Inc., Case No. 12-12080 (SCC), petition date 2012-05-14 — did not produce a recorded transfer of this patent to an assertion entity, and the patent expired 2016-02-15. The limiting factor on a stronger conclusion is evidentiary, not substantive: reel/frame numbers and the correspondent of record were not retrievable, so signal 3 (repeat correspondent) cannot be scored, and the Terminal Disclaimer-free expiration means the record ends at ATC Technologies, LLC by default rather than by a documented final transfer.

I'll search for the cited references (prior art) on US 5,713,075, and separately verify the patent's own record.

Let me pull the patent's own "References Cited" section directly, plus related family citations.

Let me try alternate databases that expose the front-page "References Cited" list.

Prior-art analysis — US 5,713,075

Bottom line up front, and it is a limitation you need to know about: I was not able to retrieve the front-page "References Cited" (U.S. patent references) list for US 5,713,075. What I did retrieve is the front-page "Other Publications" list (the non-patent literature the applicant cited), taken from a USPTO-derived patent record. So the honest answer to "look at each patent citation for 5713075" is: I have the cited non-patent references, not the cited patent references, and I will not invent the latter. Details and the exact gap are flagged in §3 and §6 below.

Two housekeeping notes first:

• Date discrepancy: your task header says April 26, 2026; my environment date is 2026-09-28. I've used neither to change any patent fact.
• Identifier discipline: I did not substitute any similar number. The only recurring "5713075" collision remains JP 5713075 B2 (unrelated Japanese grant), consistent with the earlier sections.

1. Confirming the target patent (literal)

Source: https://patents.google.com/patent/US5713075/en

Critical-date computation for §102(b): with a listed priority date of 1995-11-30, the one-year §102(b) bar date is 1994-11-30. With the actual filing date of 1996-02-15, it would be 1995-02-15. I use the earlier (applicant-favorable … no, actually the later is applicant-favorable) — let me be precise: the §102(b) critical date is one year before the earliest effective filing/priority date, i.e. 1994-11-30 if 1995-11-30 is the effective date. That matters because several of the cited papers are dated 1992–1994, which straddles that line. I flag the 1994 items as date-sensitive.

2. Method note — what I actually queried

I searched Google Patents, FreePatentsOnline, and the NCBI PubChem patent record for US-5713075-A (which mirrors USPTO front-page data). I did not complete a direct query of USPTO Patent Public Search / Patent Center / the USPTO PTAB or assignment APIs — my tool budget was exhausted before I could. That is a real evidentiary gap, not a negative finding.

3. Cited prior art — the "Other Publications" list on the '075 front page

These are the references cited by the applicant during prosecution, as reflected in the PubChem USPTO-derived record for US-5713075-A (https://pubchem.ncbi.nlm.nih.gov/patent/US-5713075-A). All are printed publications — they have publication dates, not filing dates.

Note: the PubChem record lists items 1 and 8 twice (once in each of two citation fields, with and without parenthetical markers). That is a duplication artifact of the source page, not two distinct references.

My §102 assessment of these references (and the honest caveat)

No single one of the above appears to anticipate the '075's independent claims. The reason is structural and worth stating plainly:

• Every one of these references describes the environment of the invention — the satellite, space segment, NOC, NCC/GC, FES, MET, and signaling channels. That environment material lands in the preamble of the '075 claims ("In a mobile satellite system including at least one satellite and at least one network engineering/systems engineering (NE/SE) system…"), which is not the point of novelty.
• The asserted novelty of the '075 lies in the NE/SE provisioning/engineering tool — the rule-based provisioning, "working configuration" commit, Last-Used-vs-Template-Value attribute defaulting, frequency-plan overlap constraints, Satellite-Payload→SBG→Beam power balancing, and NOC database upload/reconciliation. None of the eleven cited papers is described in a way that discloses those features. On the record I retrieved, they are best characterized as §102(a)/(b) background/environment art, and as §103 fodder for the environment elements, not as §102 anticipatory art for the NE/SE claims.
• Because these were cited by the applicant and the patent nonetheless issued over them, the examiner is presumed to have considered and distinguished them.

Claim mapping — stated with an explicit caveat. You asked me to name "which claim(s)" each reference potentially anticipates. I cannot do that reliably, because the issued claim set of the '075 is not in the material I have (the supplied full text is truncated before the claims, and my searches did not return the '075 claims column). The earlier sections of this analysis flagged the same gap. So instead of inventing claim numbers:

• References 5, 10, 6, 9 and 11 (Harvey/Lunsford/White/Whalen/Fasulo) touch subject matter that would sit in the claim preamble / environment recitals of the independent system claim and the independent method claim.
• References 1, 2, 3, 4, 7 and 8 touch the call-control, FES, and air-interface subject matter that is described in the specification but is not, on my reading, the characterized point of novelty.
• I assert no §102 anticipation of any specific claim on this record. Any such assertion would require the literal claim text.

4. The patent references I could not retrieve (explicit gap)

The '075 front page should contain a "References Cited → U.S. Patent Documents" table (typically a dozen-plus U.S. patents from 1992–1995 in classes H04B/H04Q/H04M). I did not obtain it. My queries returned other patents' citation lists that merely happen to cite the '075 (forward citations — see §5), not the '075's own backward patent citations. I am not going to populate that table with look-alike numbers.

To close this gap, the following will give you the list directly:

1. USPTO Patent Public Search (https://ppubs.uspto.gov) — pull the '075 "References Cited" from the front page image/text.
2. Google Patents "Patent Citations" section — https://patents.google.com/patent/US5713075/en (the citation table is rendered below the description; my fetches repeatedly returned the description body instead).
3. The '075 PDF at https://patentimages.storage.googleapis.com/.../US5713075.pdf — front page, left column ("U.S. Patent Documents").
4. Family members US 6,185,409 B1 and US 6,272,341 B1, whose front pages carry largely overlapping citation lists.

5. Forward citations (references that cite the '075) — retrieved

For completeness, since forward citations are probative of the '075's perceived relevance:

6. Confidence and limitations (read this before relying on any of it)

• High confidence: the patent's identity, bibliographic data, and the eleven non-patent references listed in §3 as the applicant-cited "Other Publications," including their dates as recorded (https://pubchem.ncbi.nlm.nih.gov/patent/US-5713075-A).
• Low confidence / not established: the U.S. patent references cited on the '075 front page — I did not retrieve this list, and I am not guessing at it.
• Not established at all: any claim-number-specific §102 anticipation. The issued claims of the '075 were not available to me (the supplied full text is truncated at "…to add an ACU to", and searches did not surface the '075 claims column). Any claim-level anticipation statement would therefore be fabrication, and I have declined to make one.
• Date-sensitivity flagged: items 7 and 8 (both "1994" without a month) sit near the 1994-11-30 §102(b) critical date derived from the listed 1995-11-30 priority date. If the effective priority date is instead the 1996-02-15 filing date, the bar date moves to 1995-02-15 and every item in §3 becomes §102(b) art. Resolve the priority claim before relying on these dates.
• Contradiction check vs. earlier sections: no contradiction. The earlier sections flagged the missing claim text; this task hits the same wall and additionally reveals a second missing piece — the backward patent-citation list. Both are product of the same truncated source, not new inconsistencies.

If you can supply the '075 front page (or the '409/'341 front pages, which share most citations) plus the issued claim set, I can complete the claim-by-claim §102 mapping properly.

I'll research the prior art cited on this patent's page, since the "Prior Art" section content wasn't included in what was provided to me.

I now have the cited prior art. Let me ground the identity of the key examiner-cited U.S. references before analyzing them.

Obviousness Analysis — U.S. Patent No. 5,713,075 under 35 U.S.C. § 103

0. Threshold notes, sources, and a contradiction flag

Governing law. The '075 patent's earliest priority is 1995‑11‑30 (provisional 60/007,804) and it was filed 1996‑02‑15, granted 1998‑01‑27, expired 2016‑02‑15 (fee‑related). It is therefore a pre‑AIA patent: pre‑AIA 35 U.S.C. § 103(a) applies, decided under the Graham v. John Deere factors as refined by KSR Int'l v. Teleflex. A "person having ordinary skill in the art" (PHOSITA) is measured as of the invention date (1995).

⚠️ Contradiction flag against the earlier-generated sections. The earlier Patent summary section stated that the "novel subject matter is the engineering and provisioning tool (rule‑based provisioning, 'working config‑uration' commit, attribute defaulting via Last Used vs. Template Value, frequency‑plan overlap checks, power balancing …)." The issued claim text for the '075 family (verified this session) does not recite any of those details. Those features appear only as specification "requirements"/prose describing the NE/SE tool — not as claim limitations. The granted independent claims are far broader than the earlier summary implied. That correction materially changes the §103 posture (an obviousness challenge is much easier against the claims as actually issued). I flag this rather than repeating the earlier characterization.

⚠️ Claim-text caveat. The full patent text supplied to me was truncated (it ends mid‑sentence at "add an ACU to"), so I do not have the literal '075 claim column. I have instead retrieved the claims of the same‑family, same‑specification continuations, which are the best available proxy:

• US 6,272,341 B1 (App. 08/931,622, filed 1997‑09‑16) — expressly "a continuation of application Ser. No. 08/601,749 filed Feb. 15, 1996 now U.S. Pat. No. 5,713,075." Claims 1–26. Source: https://uspto.report/patent/grant/[6272341](/patent/6272341)
• US 6,185,409 B2 (App. 09/007,172, filed 1998‑01‑14; CIP) — recites the '075 as its grandparent, "Ser. No. 08/601,749 now U.S. Pat. No. 5,713,075." 35 claims. Source: https://patents.searchlight.law/doc/US6185409

I analyze the family independent claims (mobile‑satellite‑system claim + engineering‑method claim) as the proxy, and I label every legal conclusion accordingly.

⚠️ Prior-art caveat. You asked me to "[u]se the results from the Prior Art section of this page." That section's text was not included in the material provided to me. I reconstructed it from the patent's own front‑page citation tables published by third‑party mirrors of the family. Sources below.

1. The prior art of record on the '075 family

1.1 U.S. patents cited

The examiner‑cited '225 (DeSantis) was the primary reference; the Wiedeman/Diekelman/Monte/Ladue/Loral group were cited on the family's 1998–1999 continuations.

1.2 Non‑patent literature cited (applicant‑cited; all pre‑1995)

Retrieved from the '075‑family citation tables (PubChem patent mirror: https://pubchem.ncbi.nlm.nih.gov/patent/US-5713075-A and https://uspto.report/patent/grant/6272341):

• Lunsford, J. et al., "The AMSC/TMI Mobile Satellite Services (MSS) System Ground Segment Architecture," AIAA, 1992, pp. 405–426.
• Harvey, T. et al., "MSAT Network Communications Controller and Network Operations Center," AIAA, 1993, pp. 270–279.

• Motorola, "IRIDIUM Technical Fact Sheet," June 1990.

Key §103 observation: these NPL references are not disparate art. They are a single body of contemporaneous engineering literature describing one system — the AMSC/TMI MSAT MSS. Several are cross‑incorporated. The '075 specification relies on them: the "Background Art" section is, in substance, a recitation of these documents (the White reference is expressly incorporated, and the Lunsford/Whalen system description is reproduced at length).

2. Level of ordinary skill in the art (POSITA)

A PHOSITA in late 1995 would be a communications‑systems engineer or network‑management software engineer with a B.S. in electrical engineering/computer science and ~3–5 years' experience in satellite or wireless network operations, conversant with (i) satellite resource management (beams, transponder frequency/power allocation, frequency reuse plans), (ii) circuit‑switched call processing at an earth station, and (iii) conventional computer/database configuration‑management tools and OSI/SNMP network management. Critically, the AMSC literature of record is itself written by such persons at this level — the references are the work product of the ordinary artisan, not of a pioneer.

3. The proxy independent claims, reduced to their elements

Claim 1 of the '341 (and claim 1 of the '409) reduces to:

Method claim (14 of '409 / 2 of '341): the same acts plus "collecting and reporting traffic and performance data for future planning."

These are functional, result‑oriented recitations of ordinary network‑engineering and provisioning operations. None of them recites a specific algorithm, data structure, message format, or hardware — which is exactly why they are vulnerable.

4. Element‑by‑element mapping

4.1 Elements A–D (the satellite network per se): squarely in the prior art

Elements A–D are disclosed, in combination, by the AMSC/MSAT references:

• Lunsford '92 (AMSC/TMI MSS Ground Segment Architecture) discloses the ground segment in which the NE/SE sits — the NOC/NCC/FES/MET decomposition.
• Harvey '93 (MSAT Network Communications Controller and Network Operations Center) discloses the NOC and NCC, including the real‑time circuit‑allocation function and the circuit‑pool/Group‑Controller organization recited in element D. (The '075 specification's own description of circuit pools "managed by Group Controllers (GCs) within the NCC" tracks this reference nearly verbatim.)
• McCauley '94 discloses the FES function, including PSTN/private‑network interfaces and call completion — element C.
• Whalen '92 discloses the space segment: multiple beams, L‑band/Ku‑band transponders, power/EIRP — element A.
• Wiedeman '404 independently discloses a satellite telephony system with gateways, a network control center, and a network database, performing allocation of satellite and terrestrial resources — an alternative but cumulative disclosure of A–D in the patent literature.
• White '92 (incorporated by reference into the '075) discloses the signaling architecture that makes the NCC↔FES↔MET control loops work.

No §103 difficulty with A–D. They are admitted prior art in the '075's own Background Art section.

4.2 Element E (the NE/SE system and processes e1–e6): disclosed/obvious from the same references plus admissions

This is the only element that could bear novelty, and it is the weakest link in the patent:

Independent disclosure of the NE/SE entity and its functions. The '075's own Background Art describes a Network Management System (NMS) comprising three functional entities — CMIS, Network Engineering, and System Engineering (NE/SE) — and attributes to them:

• Network Engineering: "reconciles expected traffic loads with the capability and availability of space and ground resources to produce frequency plans for the different beams within the system," and "defines contingency plans for failure situations";
• System Engineering: "engineers the subsystems, equipment and software which is needed to expand capacity to meet increases in traffic demands and to provide new features and services which become marketable to subscribers."

Map that language onto the claim:

This material is presented in the patent as background/prior art, which makes it an admission against interest under §103. A PHOSITA reading Lunsford/Harvey/Whalen would have understood the MSAT ground segment to already include a network‑engineering function that performs traffic‑vs‑capacity reconciliation and beam frequency planning.

What remains arguably "missing" from that admission is: (i) the recitation of the NE/SE as a discrete system "operatively connected to the NOC", and (ii) elements (e5) external‑organization path configuration and (e6) work‑order logistics. Neither is a patentable advance:

• (i) Operative connection of NE/SE to NOC. Where an existing NMS already contains an NE/SE function, connecting it to the NOC over the existing MSS internetwork is the only workable architecture. The '075 specification itself does not describe anything more than message exchange over DECnet/ASN.1 and the MSS internetwork — a standard, pre‑existing network. Obvious to try, with a predictable result.
• (e5) External‑organization paths. The '075's external organizations (CMIS; Marketing; BBS/roaming databases such as CORD and NACN; PSTN agencies; the GWS MAP) are pre‑existing entities; CMIS is admitted prior art in the same paragraph that admits Network/System Engineering. Wiedeman '404 discloses a network database (20) and network coordinating gateway (28) coupled to gateways and terrestrial networks — i.e., configuring communication paths among network and external entities. Configuring a computer's communication paths to a known external party is the epitome of a predictable, non‑inventive design step.
• (e6) Work‑order generation and traffic/performance data collection. Generating work orders to reconcile a "desired" configuration with an "actual" configuration is conventional configuration‑management practice (the same discipline as OSI/CMIP and DEC's DECmcc network‑management products of the early 1990s — note that the '075 specification itself names DECmcc and DECnet Phase V OSI as the environment). Collecting and reporting traffic/performance statistics was likewise routine (DECps performance reports, call‑detail records, the switch's OM groups; the '075 simply uses these).

5. Combinations that render the claims obvious (with motivation)

Theory 1 — Lunsford '92 + Harvey '93 + White '92 + McCauley '94 + Whalen '92 (the AMSC/MSAT ground‑segment set), in view of the '075's own background admissions

What each contributes: A (Whalen); B/C/D (Harvey, McCauley); the NE/SE entity and its traffic/frequency/capacity function (Lunsford + applicant's admitted NMS description); signaling/interface fabric (White).

Motivation to combine — this is nearly self‑evident because the references are the same system:

1. Common ownership / common project / common disclosure. These are AIAA/IMSC papers describing the very MSAT MSS the '075 claims to manage. Combining them is not combining "references"; it is reading one system's documentation. KSR ("familiar elements according to known methods") applies a fortiori.
2. Express cross‑incorporation — White '92 is incorporated by reference in the '075 specification; Lunsford/Whalen supply the architecture that the '075's Background Art paraphrases.
3. The references state the very problem the claim addresses — reconciling traffic demand against finite satellite capacity and expanding the ground segment as demand grows. That is a design incentive articulated in the art itself, satisfying KSR's "motivation" prong without resort to applicant's insight.

Result: claims 1/14 (and dependent claims 7/20's enumerated resource‑configuration tasks, claims 12/25's partitioning of satellites/beams/control groups into circuit pools, virtual networks and frequency plans) are obvious.

Theory 2 — DeSantis '225 in view of Whalen '92 and Harvey '93

Contribution: DeSantis discloses variable‑bandwidth, variable‑center‑frequency multibeam satellite routing — i.e., allocating transponder bandwidth/center frequencies among beams and reconfiguring that allocation as traffic demands change. This is precisely the technological substrate for the claim's "producing frequency plans for different geographical regions" and for the specification's Frequency Usage Blocks, Frequency Plans, and Beam/SBG/Payload power balancing requirements (and is why the examiner adopted '225 as the primary reference).

Motivation: A system engineer allocating L‑band spectrum among hundreds of beams and circuits has one recognized way to express that allocation — a frequency plan mapping Ku‑band to L‑band per beam/control group. DeSantis supplies the multibeam variable‑allocation teaching; Whalen supplies the MSAT space segment (29 MHz L‑band allocation, EIRP limits); Harvey supplies the NCC that consumes the assignment. Motive: spectrum and power are scarce and the art expressly seeks "satellite design efficiency" via matching connectivity/coverage to traffic demand (DeSantis, quoted). Predictable result: yes.

Theory 3 — Wiedeman '404 ('404 family) in view of Harvey '93

Contribution: '404 discloses a satellite telephony system with gateways, a network control center, a user database, a network coordinating gateway, allocation of satellite and terrestrial resources, and data network interconnection of system controller and gateways — i.e., the same problem/solution architecture for a differently‑orbited satellite system.

Motivation: Same field of endeavor, same problem (allocate scarce satellite resources across gateways/beams and interconnect the management entities over a data network); '404's very title recites "allocating satellite … resources." A PHOSITA looking at non‑GEO satellite telephony would find '404's resource‑allocation and network‑interconnection teachings reasonably pertinent to the MSAT ground segment's NE/SE–NOC interfaces (claims 2/4, 15/17 message types; claim 11/24 NOC database uploads).

Theory 4 — General‑purpose network/configuration‑management and database art (OSI/CMIP, DECmcc, SNMP, RDBMS, client‑server), in view of any of Theories 1–3

This theory disposes of the dependent claims, which recite nothing but conventional software engineering:

6. Secondary considerations / possible rebuttals

• Teaching away: none identified. No reference disparages automated network‑engineering/provisioning tools; to the contrary, the art asks for efficient resource utilization and capacity growth.
• Unexpected results: none. Every claimed function (traffic vs. capacity comparison; frequency planning; power balancing; provisioning; rule validation; DB reconciliation) produces the result a PHOSITA would predict.
• Long‑felt need / commercial success: the need was articulated in the prior art itself (DeSantis' "satellite design efficiency"; the MSAT literature's capacity‑growth imperative), which cuts against the patent. And the '075 expired 2016‑02‑15 for failure to pay maintenance fees — a fact tending to undercut any commercial‑success narrative, though I note this is a weak, non‑dispositive inference (assignment-chain churn through Motient → Mobile Satellite Ventures → ATC Technologies → LightSquared-era financing complicates it).
• Copying: no evidence of record.
• §102(e) nuance to double‑check: the Wiedeman/Diekelman/Monte/Ladue patents were granted in 1996–1998, i.e., after the '075's filing. They are available only as pre‑AIA §102(e) art (US patent effective as prior art as of its pre‑'075 filing date). Their exact filing dates should be confirmed before relying on them; the AMSC NPL references (1992–1994) and DeSantis '225 (1989) have no such issue and are independently sufficient.

7. Bottom line

Claims 1 and 14 (and their '341/'409 analogues) would very likely have been held obvious under pre‑AIA §103(a):

1. Elements A–D are admitted prior art and independently disclosed by the AMSC/MSAT references of record (Lunsford, Harvey, White, McCauley, Whalen) and by Wiedeman '404.
2. Element E's functional recitations (traffic‑vs‑capacity comparison, frequency planning, capacity expansion, external‑organization paths, work‑order logistics) are described in the '075's own background as the functions of the pre‑existing "Network Engineering" and "System Engineering" entities of the NMS and are all routine network‑engineering/provisioning operations.
3. The motivation to combine is supplied by the references themselves (same system, same problem: reconcile growing traffic against scarce satellite capacity and expand the ground segment), which satisfies KSR's design‑incentive/market‑demand and "predictable results from familiar elements" rationales without importing applicant's hindsight.
4. DeSantis '225 supplies the multibeam variable‑bandwidth/frequency‑allocation teaching that grounds the "frequency plans for different geographical regions" and the specification's FUB/power‑balancing subject matter — which is presumably why the examiner selected it as the primary reference.
5. The dependent claims add only conventional computing/network‑management expedients (client‑server, event listeners, FTP, rule validation, DB reconciliation, GUI graphs, remote terminal emulation) that were well known by 1995.

The strongest counter‑argument for the patentee would be a Threat of claim construction point rather than a novelty point: that the AMSC references describe the NE/SE functions as manual/organizational activities performed by engineers, and that the claims require an integrated NE/SE system operatively connected to the NOC. Given the breadth of "operatively connected" and the absence of any structural or algorithmic limitation in the claims — and the express statement in the art that these functions belong to the NMS alongside CMIS — I assess that argument as unlikely to succeed, particularly under KSR's "obvious to try" and "automation of a known manual process" lines.

Confidence: High on the prior‑art identification and on the elemental mapping for the AMSC/MSAT references and DeSantis '225 (all verified this session). Moderate on the precise wording of the '075's own claim 1, because the issued claim column was not available to me; the analysis rests on the same‑specification family claims as a proxy. I have not corrected or substituted any patent number or identifier, and I flag the JP 5713075 B2 false‑positive collision (an unrelated Japanese grant) as I did previously — it does not feature in this analysis.
