US 6285745

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

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

Let me confirm the full claim set and check for any PTAB/CAFC record.

US Patent 6,285,745 — Analyst Summary

Scope note: I searched for the literal identifier 6285745. All findings below are for U.S. Patent No. 6,285,745 B1 only. I found no CAFC 2026 docket entry, IPR, or district-court case naming this patent; details and caveats on that are at the end.

1. Bibliographic data (authoritative — from the full patent text)

Family / priority chain: This patent is a continuation-in-part of Ser. Nos. 08/353,281 (now US 5,680,443), 08/371,906 (now US 5,631,948), 08/539,952 (now US 5,661,782) and 08/557,749 (now US 5,812,639). A same-day sibling application, US 08/598,767 (now US 6,215,858 B1, "Analog terminal internet access," issued 2001-04-10, 15 claims), shares the identical specification and inventors but has different claims. Google Patents lists the sibling as a priority/related application on the '745 record.

2. Abstract (verbatim from the authoritative text)

"A system and method of affecting transfer of a message such as a voice message from one centralized messaging system in a first switched telephone network to a centralized messaging system in a remote second switched telephone network wherein each of said telephone networks includes central offices connected to subscriber terminals. The message is inputted in analog form into one of the terminals connected to the first telephone network and stored in digital form in the centralized messaging system in that network. The message is then transferred from that centralized messaging system to the centralized messaging system in the second telephone network where it is stored. The message is then delivered by retrieval or an outgoing call to an addressee terminal in the second telephone network. The transfer between telephone networks and their respective centralized messaging services occurs via an internetwork to which each of the centralized messaging systems are connected. The transfer occurs through connectionless packet signaling using TCP/IP protocol."

Technical field: switched communications networks and voice-mail services; specifically, mailbox-to-mailbox communication between multiple mailbox systems using connectionless packet delivery via established networking arrangements (AIN/SS7 in one embodiment; the Internet in another).

Disclosed embodiments: (a) mailbox-to-mailbox transfer over the existing CCS/SS7 and AIN (TCAP/ISCP) network; (b) mailbox-to-mailbox transfer over the Internet via a router/gateway interface; (c) "public" / for-hire mailboxes for non-subscribers, including reply-request and 900-service variants; (d) a multimode Intelligent Peripheral (IP) with selectable protocol-conversion modules (voice recognition, voice synthesis, fax server, E-mail server) driven by AIN triggers (FIGS. 10–13).

3. Independent claims — plain-language overview

Important caveat on claim text: the authoritative full text supplied for this record ends at "Background Art" and does not include a claims section. The claim text below is drawn from the Justia reproduction at https://patents.justia.com/patent/6285745, which appears to end mid-document at claim 11 (the excerpt transitions to "Patent History" immediately after claim 11). I therefore cannot confirm the total number of claims or whether additional independent claims exist. Treat the set below as the best available but not verified-complete.

Claim 1 — Communications system (independent, system)

A system with two switched telephone networks, each built from central offices joined by trunks with subscriber lines and telephone terminals. Each network contains a centralized messaging network that addressably stores, in digital form, messages that were originally input in analog form. The two networks are linked by an "Internet" defined as multiple remotely spaced, diverse-type computer networks joined by links and using a common protocol to give connectionless packet service between them. Each centralized messaging network attaches to that Internet through an addressable protocol-translating interface. A transferred message is addressed to a recipient interface by that interface's address, and it also carries an address identifying a subscriber line in the destination telephone network; that subscriber-line address is used by the destination messaging network to store the message retrievably.

Claim 8 — Method (independent, method)

In a communications network of multiple switched telephone networks, each with COs, subscriber lines/terminals, and a centralized messaging system, and each interfaced to an Internet of diverse linked computer networks using transmission control protocols (TCP) over an Internet protocol (IP) for connectionless packet service, the method comprises:

1. in response to dialing a number at a terminal in a first network, connecting that terminal to the first network's centralized messaging system and storing a message there that includes (i) a portion audibly input at the terminal and (ii) an address identifying a destination subscriber line in a second network;
2. forwarding the message from the first messaging system to the second network's messaging system via the Internet, using TCP/IP-style connectionless packet delivery;
3. storing the forwarded message, including the address, at the second messaging system; and
4. delivering the audibly-input portion to a terminal connected to the identified subscriber line in the second network.

Dependent claims (as reproduced)

• 2 (dep. 1): destination network provides retrieval of the stored message and conveyance to a terminal on the identified line.
• 3 (dep. 2): the terminal is given the stored message in analog form.
• 4 (dep. 1): the common protocol is TCP/IP.
• 5 (dep. 1): each centralized messaging network is a voice messaging system with voice mailboxes tied to directory numbers of subscribing lines.
• 6 (dep. 5): the destination-side network has a database of assigned directory numbers, searched on message receipt; storage address depends on the search result.
• 7 (dep. 6): transfer is mailbox-to-mailbox between originating and destination networks.
• 9 (dep. 8): the audibly input portion is received in analog form at the central office serving the terminal.
• 10 (dep. 9): delivery provides the portion in analog form.
• 11 (dep. 10): delivery is responsive to a telephone call placed to the second network.

4. Litigation / CAFC 2026 check

• No CAFC 2026 docket naming US 6,285,745 was found. My docket searches surfaced 2026 Federal Circuit activity in in re Yechezkal Evan Spero (No. 25-1306, involving U.S. 11,208,029) and a 2026 E.D. Tex. final judgment in Headwater Research LLC v. Cellco Partnership d/b/a Verizon Wireless (asserting U.S. 9,215,613 and U.S. 8,589,541) — neither involves the '745 patent.
• I found no IPR/PGR record tied to the '745 patent. A PTAB final written decision referencing a "Farris" prior-art reference (petition 1548747) appears to concern a different patent with claims 1–21; I could not tie it to 6,285,745 and am not asserting that it does.
• Uncertainty flag: absence of a hit in my searches is not affirmative evidence that no proceeding exists. USPTO PatentCenter / PTAB and CAFC PACER should be checked directly for a definitive negative.

5. Identifier-collision warning (interpreted literally, per instruction)

A different patent bearing the same numeric designation 6285745 exists in Japan (JP Patent No. 6285745, "移築された煉瓦壁の支持構造" — support structure for a relocated brick wall; application 2014-032752; published 2015-09-03; IPC E04G 23/02). That is not US 6,285,745 and is unrelated subject matter. Likewise, note that US 6,215,858 shares this patent's title, specification and inventors — do not conflate the two.

6. Points I cannot confirm

• Total claim count for US 6,285,745 and whether further independent claims exist beyond claims 1 and 8 (the source excerpt is truncated).
• Exact claim language for any claims after claim 11.
• Minor date discrepancy: Unified Patents lists the priority date as 1994-12-04; the authoritative record and Google Patents state 1994-12-05. I use 1994-12-05.
• One PTAB document refers to Ser. No. 08/598,767 as filed "Feb. 2, 1996"; the authoritative record shows 1996-02-09 for the 08/598,7xx filings.

I'll research litigation involving US Patent 6,285,745. Let me start with targeted searches.

The first round produced false positives (e.g., 6,687,745, 10,687,745, 6,624,761). Let me narrow to the exact patent and check litigation-specific sources.

Still no direct litigation hits. Let me probe litigation databases and possible asserting parties more specifically.

Summary of findings

I could not identify any litigation involving U.S. Patent No. 6,285,745. Based on the searches I was able to run against litigation-related sources (Unified Patents portal, CourtListener/PACER-derived materials, Justia dockets, Docket Alarm/PTAB materials, and general web indexing), no case was found in which US 6,285,745 was asserted as a patent‑in‑suit, challenged in a declaratory judgment action, or petitioned in an IPR/PGR.

Important caveat on search quality

This should be treated as a "not found," not a confirmed "none exists" conclusion. My searching was limited (the tool stopped me early), and litigation databases are not fully reflected in general web indexing. A definitive negative would require direct querying of:

• Unified Patents litigation portal — https://portal.unifiedpatents.com/litigation/caselist (searched via general query; no entry surfaced for 6285745)
• PACER / CourtListener RECAP dockets
• USPTO PTAB (IPR/PGR/CBM) and USPTO Patent Center assignment & reexamination records
• RPX Insight and Docket Alarm case archives
• CAFC docket search

I recommend running the exact string 6285745 (and the formatted 6,285,745) as a party/patent filter within those databases directly.

False positives I explicitly ruled out

Several results returned similar but different patent numbers, which must not be confused with 6,285,745 (per the strict-instruction rule, I did not auto-correct these):

None of these involve US 6,285,745.

What the record does show for US 6,285,745 (context, not litigation)

• Title: "Analog terminal internet access"
• Patent number: US 6,285,745 B1 — granted/published 2001‑09‑04
• Application: US 08/598,769, filed 1996‑02‑09
• Inventor(s): Dale Bartholomew; Robert D. Farris
• Original assignee: Bell Atlantic Network Services, Inc.
• Current assignee (per Google Patents listing): Verizon Patent and Licensing Inc. (via Verizon Services Corp., change of name from Bell Atlantic, 2007‑04‑23; then assignment to Verizon Patent & Licensing, 2014‑05‑08)
• Priority date: 1994‑12‑05 (continuation-in-part of US 08/353,281, 08/371,906, 08/539,952, and 08/557,749)
• Legal status: Expired – Fee Related; anticipated expiration 2014‑12‑05

The patent is a continuation-in-part related to the "Voice Mail Communication With Call Blocking" family (which issued as US 5,680,443; 5,631,948; 5,661,782) and to "Data Mail Communication With Call Blocking" (US 5,812,639), and it lists US 6,215,858 (a sibling "Analog terminal internet access" patent, also Bell Atlantic) in its family.

Bottom line

• Litigation known for US 6,285,745: none identified.
• Given the patent's expiration in 2014 and its ownership by Verizon/Bell Atlantic (an operating company, not a frequent NPE‑style enforcer), a low or zero litigation profile is plausible, but I cannot represent this as definitive.
• To confirm the negative authoritatively, query the Unified Patents litigation caselist, PACER/CourtListener, PTAB, and the USPTO Patent Center (assignment/reexam) records for the exact identifier 6285745.

If you can point me at a specific database endpoint or allow additional searches, I can attempt to verify against those sources directly rather than relying on general web indexing.

I'll start by searching for any PTAB activity on US 6,285,745.

Let me search more specifically for this patent and any litigation/PTAB history.

Let me check the Unified Patents portal entry and PTAB E2E for this patent, plus the Vonage litigation angle.

Proceedings overview

Total AIA trial proceedings on US 6,285,745: 0. The structured block provided in this task — the canonical list from the USPTO Open Data Portal — returns no AIA trial proceedings for this patent, and my independent web searching surfaced none either (no IPR, PGR, or CBM docket in which US 6,285,745 appears as the challenged patent). The breakdown by status is therefore: active 0 / claims invalidated 0 / claims sustained 0 / settled 0 / institution denied 0.

Bottom line for a defendant: there is no PTAB record to lean on — but you almost certainly do not need one. US 6,285,745 issued 2001-09-04, ran from a 1994-12-05 priority date, and Google Patents' structured data records it as expired as of 2014-12-05 with the status "Expired - Fee Related." Whatever else is true, this is not a patent that can generate ongoing or forward-looking infringement exposure today. The absence of PTAB activity is not a "the patent is hardened" signal here; it is largely a byproduct of the patent having aged out before the AIA trial regime had a chance to matter for it (AIA trials started 2012-09-16, leaving only a ~2-year window before expiration).

Per-proceeding entries

None. There is no proceeding number to report, no petitioner, no panel, no institution decision, no Final Written Decision, no settlement, and no Federal Circuit appeal for this patent. Per the task constraints, I am not going to manufacture a docket to fill out the template.

Because the per-proceeding template cannot be populated, the more useful service is to tell you what did not happen and why, and to clear away the look-alike dockets that a search will throw at you.

What I verified, and how

Disclosure of a limitation: I exhausted my search budget and was not able to directly query the PTAB E2E docket interface at https://ptacts.uspto.gov/ptacts/ or run a party-name sweep on CourtListener. Given that the ODP structured data — which is the source of record here — reports zero proceedings, and that nothing in the open web contradicts it, I am comfortable stating the zero count, but I am flagging the residual verification gap rather than hiding it.

Near-miss identifiers — do NOT conflate these with US 6,285,745

These are the dockets and patent numbers that a naive search will surface, and each one is a different patent. Getting these confused is the single most likely way to file a bad IPR or a bad invalidity contention:

• US 6,282,574 — a different Verizon/Bell Atlantic patent ("Method, server and telecommunications system for name translation on a conditional basis and/or to a telephone number"), asserted in the Verizon v. Vonage line of cases. One digit off from 6,285,745.
• US 10,687,745 — Masimo's pulse-oximetry patent, subject of IPR2024-00242 (Apple Inc. v. Masimo Corp.) and the IPR2020-01722 / -01723 family referenced in the Apple–Masimo papers. Same last three digits, entirely unrelated art.
• IPR2022-01291, IPR2022-01292, IPR2022-01465, IPR2022-01466 — Apple v. Masimo, directed to the '745 patent in the 10,687,745 sense. Not this patent.
• Japanese Patent No. 6285745 (特許第6285745号, Kumagai Gumi, brick-wall support structure, registered 2018-02-09) — a JP number collision, nothing to do with the US patent.
• Unified Patents portal — the Unified portal surfaces "US-6285745-B1 / Analog Terminal Internet Access / Verizon Patent and Licensing Inc" in patent-profile and related-patent listings (e.g., alongside US-5,557,659). A profile page is not a challenge. I found no evidence of a Unified Patents-filed IPR against this patent, and you should not treat the portal appearance as one.

If a demand letter, claim chart, or prior art set you receive cites "the '745 patent" without the full number, verify the number before you rely on any of the above.

Strategic summary

Claim status: everything is UNTESTED, and moot. No claim of US 6,285,745 has ever been canceled or confirmed in an AIA trial, so there is no claim-level PTAB record to work from — no "claims 1-5 canceled" ammunition, and equally no adverse FWD you have to litigate around. What does exist is a statutory and term-based picture that dominates the analysis. Independent claim 1 is directed to a communications system spanning two switched telephone networks, each with a centralized messaging network for addressably storing analog-originated messages, joined by an Internet using a common connectionless-packet protocol through an addressable protocol-translating interface, with the transferred message carrying an address for a subscriber line. Claims 2–7 as published are dependent claims reciting analog delivery, TCP/IP as the common protocol, voice mailboxes keyed to directory numbers, database lookup on message receipt, and mailbox-to-mailbox transfer. None of this has been adjudicated by the Board — and given the expiration, none of it is likely to be.

Estoppel landscape: essentially empty, and that cuts both ways. Because no IPR or PGR was ever filed against this patent, no § 315(e)(2) estoppel attaches to anyone. There is no petitioner, no privy, no real party in interest, and no Sotera-style stipulation anywhere in this patent's history. So a defendant today faces no PTAB-derived estoppel bar — but also inherits none of the benefit of an earlier petitioner's work product, expert declarations, or institution-decision findings. Practically, the prior-art landscape is wide open, which matters little because of the next point.

The real defensive posture is expiration, not validity. The structured data records the patent as expired on 2014-12-05 ("Expired - Fee Related"). Two consequences dominate any assertion against you today: (1) there is no ongoing or future infringement, so injunctive and forward-looking relief is off the table, and (2) under 35 U.S.C. § 286, damages are limited to the six years preceding the filing of the complaint — and a complaint filed in 2026 or later reaches back only to roughly 2020, which is after the patent expired. On the face of the record, there is no recoverable damages window left. Any demand letter premised on this patent is, at minimum, facing a severe damages problem before validity even comes into play. Note also that the patent number appears in the "expired - fee related" category, meaning a maintenance-fee lapse is the recorded cause — worth confirming against the USPTO Patent Center maintenance-fee history, since a fee-lapse expiration and a term-expiration are different administrative facts even though both end enforceability.

Pattern signals. None of the classic patterns are present: no serial petitioner, no aggregator, no patent-owner appeal campaign, no multiple-IPR cluster. That is consistent with a patent that was never a litigation centerpiece in the AIA era — and consistent with an expiration date that preceded the modern PTAB filing wave. Contrast with the parent/sibling filings from the same 1994-12-05 chain (US 5,680,442; US 5,631,948; US 5,661,782; US 5,812,639; and the same-day sibling US 6,215,858), for which I also found no PTAB activity; if you are evaluating the family as a whole, run the same check on each, because the family was prosecuted by Bell Atlantic Network Services (now Verizon Patent and Licensing Inc.) and those siblings share the same expiration-era profile.

Recommended next steps

1. Do not search for a PTAB record that does not exist. If you are a defendant, the correct framing of the PTAB question is: "no proceedings on file." Confirm independently at PTAB E2E and at the PTAB decisions page using the full patent number 6,285,745 — not "the '745 patent."
2. Check expiration first, before anything else. Pull the maintenance-fee and expiration history from USPTO Patent Center and reconcile it against the Google Patents record at https://patents.google.com/patent/US6285745/en (which shows anticipated expiration 2014-12-05) and the third-party record at https://uspto.report/patent/grant/6285745. If expiration is confirmed, build your response on § 286 and the absence of any post-expiration infringing act, not on an IPR you cannot (and need not) file.
3. If you nonetheless want a Board ruling, note the procedural reality: an IPR petition can be filed against an expired patent, and the Board has instituted in such cases, but the practical value is limited to defeating past damages — and here the § 286 window likely eliminates those anyway. Also confirm § 315(b) timing: if a complaint asserting this patent was served on you more than one year ago, you are time-barred from filing.
4. Screen your art set for the look-alikes. If a prior-art set or claim chart references US 6,282,574, US 10,687,745, IPR2022-01291/-01292/-01465/-01466, or JP 6285745, it is citing the wrong patent. Say so in writing and require re-service.
5. If a live assertion exists, request the accused-acts dates in interrogatories and a damages model identifying the pre-2014-12-05 (and pre-§ 286-cutoff) sales. If the plaintiff cannot identify recoverable accused acts, that is a dispositive or near-dispositive motion, and it costs you a fraction of an IPR.

Verification caveat: the zero-proceeding count rests on (a) the ODP structured block supplied for this task and (b) open-web searching. I was unable to complete a direct E2E docket query or a CourtListener party sweep before exhausting my search budget. Treat the zero count as high-confidence but confirm it in E2E against the exact number 6,285,745 before relying on it in a filing.

I'll research the assignment record for US 6,285,745 using the USPTO Patent Assignment Search and cross-reference sources.

Let me dig into the assignment-specific records and the USPTO assignment database.

Found a plainsite assignment record. Let me pull the parent assignment pages and look for the Verizon Patent & Licensing transfer.

Assignment & Ownership Analysis — US 6,285,745 B1 ("Analog Terminal Internet Access")

Sourcing note / limitation. My tool budget was exhausted mid-research. I was able to retrieve the Google Patents legal‑events record (embedded in the authoritative patent text you supplied), a plainsite.org assignment page for the Bell Atlantic → Verizon change of name, and an INPADOC legal‑status table for a sibling patent. I was not able to open the USPTO Patent Assignment Center / assignment.uspto.gov result set for 6285745 directly, so I could not verify every reel/frame or the correspondent of record. Items below marked [unverified] are drawn from secondary aggregators or from the Google Patents event list and should be confirmed at the Assignment Center. I did not fabricate any reel/frame, correspondent, or date.

Inventors

Unusual-pattern check — no flag. The two inventors executed the original assignment on/around the 1996‑02‑09 filing date (Google Patents legal events: "1996‑02‑09 — Assigned to BELL ATLANTIC NETWORK SERVICES, INC. … ASSIGNORS: BARTHOLOMEW, DALE; FARRIS, ROBERT D."). There is no evidence that either inventor departed Bell Atlantic within 12 months of filing, and there is no evidence of an inventor‑retained interest, a later inventor‑to‑NPE assignment, or a pre‑issuance portfolio sale. The inventor names also recur together on the sibling patent US 6,215,858 ("Analog terminal internet access," also Bell Atlantic), consistent with a normal corporate R&D team rather than an opportunistic filing.

Original assignee

Bell Atlantic Network Services, Inc. (named on the issued patent; application US 08/598,769, filed 1996‑02‑09; granted 2001‑09‑04).

• Primary line of business: an operating Regional Bell Operating Company — telephone exchange, voice‑mail, and (later) data/Internet access services. This is a premises‑based carrier, not a holding/assertion vehicle.
• Product embodying the claims: The patent's claims cover transferring a voice message between centralized voice‑mail systems in different switched telephone networks via a connectionless packet internetwork (AIN/SS7 in FIGS. 1–7; TCP/IP Internet in FIGS. 8–9). Bell Atlantic commercially offered voice‑mail/messaging services on the very network architecture described, so a practicing service is plausible — though I have no product‑marketing evidence specific to this patent (this is an inference from the assignee's business, not a documented fact).
• Current status: Operating, absorbed. Bell Atlantic merged with GTE in 2000 to form Verizon Communications Inc., and Bell Atlantic Network Services, Inc. changed its name to Verizon Services Corp. (see timeline). Verizon is a live, NYSE‑listed operating carrier. No bankruptcy, no dissolution, no fire‑sale.

Assignment timeline

The Assignment Center does carry records for this patent (reflected in the Google Patents legal‑events list). Three recorded links are visible; reel/frame and correspondent for links 1 and 3 could not be captured within my tool budget and are flagged.

1. 1996‑02‑09 (executed ~filing date) / recorded [unverified] — Reel [unverified]

• Conveyance: Assignment of assignors' interest
• Assignor: Dale Bartholomew; Robert D. Farris
• Assignee: Bell Atlantic Network Services, Inc.
• Correspondent: [not retrieved] — records of this era for a Baby Bell are typically filed by in‑house or carrier‑side corporate IP counsel, but I did not confirm the name, so I make no call.
• Context: Original employment/obligation‑to‑assign transfer to the operating company.

2. 2000‑08‑01 (executed) / recorded 2007‑04‑23 — Reel 19193/346 (plainsite.org), possible sibling reel 019562/0140 (INPADOC, see note)

• Conveyance: Change of Name
• Assignor: Bell Atlantic Network Services, Inc.
• Assignee: Verizon Services Corporation, 1320 North Court House Rd, Arlington, VA 22201
• Correspondent: [not retrieved]
• Context: Change of name only — internal reorg flowing from the Bell Atlantic/GTE merger into Verizon; no change in beneficial ownership. Executed 2000‑08‑01 but recorded 2007‑04‑23 (≈6.7‑year lag), the signature of a bulk cleanup recording rather than a sale.
• Flag on the reel number: plainsite reports 19193/346 for this change of name, while an INPADOC legal‑status table for sibling patent US 6,104,711 reports REEL/FRAME 019562/0140 for a "CHANGE OF NAME; ASSIGNOR: BELL ATLANTIC NETWORKS SERVICES, INC." → "VERIZON SERVICES CORP." recording (event code AS, 2007‑07‑17). These are two different reel numbers, so either (a) two separate change‑of‑name recordings exist, or (b) plainsite's "19193/346" is a plaiinsite‑internal identifier rather than a USPTO reel/frame. I could not resolve this and cannot certify which reel applies to 6,285,745. Treat both as [unverified].
• Duplicate entry flag: The Google Patents legal‑events list shows the 2007‑04‑23 change‑of‑name entry twice ("Assigned to VERIZON SERVICES CORP. … CHANGE OF NAME"). This is most likely a duplicate recordation or a mirrored event in the aggregator, not two distinct transfers. Noted as a data‑quality issue, not a second assignment.

3. 2014‑05‑08 / recorded [unverified] — Reel [unverified]

• Conveyance: Assignment of assignors' interest
• Assignor: Verizon Services Corp.
• Assignee: Verizon Patent and Licensing Inc.
• Correspondent: [not retrieved]
• Context: Internal reorg / patent‑holding consolidation — Verizon Services Corp. assigned to Verizon Patent and Licensing Inc., the Verizon family's IP‑holding and licensing subsidiary. This is the last recorded link; the patent expired 2014‑12‑05 (anticipated expiration; Google Patents status "Expired – Fee Related").

Bottom line on the chain: inventors → Bell Atlantic Network Services, Inc. → (change of name) Verizon Services Corp. → Verizon Patent and Licensing Inc. The patent never left the Bell Atlantic/Verizon corporate family.

NPE / troll-pattern signals

1. Shell-entity transfer — NOT PRESENT. Every assignee is inside the Bell Atlantic/Verizon family: Bell Atlantic Network Services, Inc.; Verizon Services Corporation; Verizon Patent and Licensing Inc. The recorded assignee address (1320 North Court House Rd, Arlington, VA 22201) is a Verizon corporate address, not a registered‑agent/commercial‑mailbox service. Although "Verizon Patent and Licensing Inc." carries a "Licensing" suffix, the name‑based tell is overridden by the fact that it is a wholly owned holding subsidiary of a live operating carrier, not a single‑purpose assertion vehicle. No Delaware/Texas single‑member LLC appears anywhere in the chain.

2. Known asserter in the chain — NOT PRESENT. None of the three assignees matches any entry on the referenced NPE lists (Acacia, Marathon, Intellectual Ventures, IPNav, Wi‑LAN, Mosaid/Conversant, Vringo, Pendrell, Innovatio, MPHJ, Lumen View, Round Rock, Document Generation Corp, Spangenberg entities). All three are Verizon/Bell Atlantic entities and none is surfaced by Unified Patents or RPX as a high‑frequency plaintiff on this patent.

3. Repeat correspondent across the chain — UNCLEAR / not establishable. I was unable to retrieve the attorney or agent of record for any of the three links, so I cannot say whether one correspondent recurs. No finding either way — this is a genuine evidence gap, not a negative.

4. Cascading transfers — NOT PRESENT. Only three recorded events spanning 1996 → 2014 (≈18 years), and two of the three are not sales at all (a change of name and an intra‑group consolidation). There is no cluster of chained LLC assignments inside 24 months, and no shared correspondent/shell address pattern to point to.

5. Pre-litigation transfer — NOT PRESENT. The prior litigation analysis found no infringement suit naming US 6,285,745 (see litigation summary above). With no suit, there is no pre‑litigation transfer window to assess. The final assignment (2014‑05‑08) is not followed by an identified assertion and post‑dates the patent's practical end of life (expiration 2014‑12‑05).

6. Bankruptcy fire‑sale — NOT PRESENT. Neither Bell Atlantic nor any Verizon predecessor/successor entered Chapter 7/11 in connection with these assets. The only "transfer" is a change of name and an intra‑group assignment, the opposite of a distressed sale.

7. Privateering — NOT PRESENT. There is no transfer to a third‑party NPE that would assert on Verizon's behalf. All title stays within Verizon; nothing is spun out to an outside enforcer.

8. Defensive aggregator (anti‑NPE) — NOT PRESENT. The chain does not terminate at RPX, AST, LOT Network, Unified Patents, or OIN. It terminates at a Verizon holding subsidiary.

Verdict

Operating-company assertion — with an explicit caveat on the "assertion" prong.

The ownership chain is a 100% intra‑operating‑company line: inventors → Bell Atlantic Network Services, Inc. (1996 original assignment) → Verizon Services Corp. via Change of Name executed 2000‑08‑01 / recorded 2007‑04‑23 → Verizon Patent and Licensing Inc. (2014‑05‑08) — with zero NPE signals (no shell transfer, no known asserter, no cascading LLC chain, no fire‑sale, no privateering) and no defensive‑aggregator terminus. The patent never left the Bell Atlantic/Verizon family and expired 2014‑12‑05.

Important caveat: the "operating company … suing actual competitors" element is not documented for this patent — the prior litigation pass found no suit naming US 6,285,745, and the current assignee (Verizon Patent and Licensing Inc.) is a holding/licensing subsidiary, not itself a product shipper. If a strict "currently litigating on this patent" predicate is enforced, the record reads as non‑asserting operating‑company ownership rather than active assertion. Either way, the answer to the NPE question is firmly negative.

Verify at: USPTO Patent Assignment Center — search patent number 6285745 → https://assignmentcenter.uspto.gov/ (mirror: https://assignment.uspto.gov/patent/index.html).

Open items I could not close (recommend re‑running): (i) confirm the actual USPTO reel/frame for each of the three links; (ii) resolve the 19193/346 vs 019562/0140 discrepancy for the 2007 change‑of‑name recording; (iii) capture the correspondent of record on each link (the key NPE tell, currently unretrieved); and (iv) confirm whether the 2007 entry is a duplicate recording of a single change‑of‑name document.

I'll search the USPTO and patent databases for the specific identifier 6285745 and its cited prior art. Let me run several targeted queries in parallel.

I have the citation lists from two sources that don't fully agree. Let me resolve the discrepancy and pull the front-page references and claims directly.

Prior-Art Analysis — U.S. Patent No. 6,285,745 B1 (literal identifier: 6285745)

0. Identifier control (strict-rule compliance)

Every reference below is tied to the single identifier 6285745 = US 6,285,745 B1, "Analog terminal internet access," App. No. 08/598,769, filed 1996-02-09, issued 2001-09-04, inventors Dale Bartholomew / Robert D. Farris, original assignee Bell Atlantic Network Services, Inc.

I did not import references from, and did not auto-correct toward, any of the look-alike identifiers flagged earlier in this file: US 6,282,574, US 10,687,745, US 6,687,745, US 6,624,761, IPR2022-01291/-01292/-01465/-01466, or JP 6285745 (Kumagai Gumi brick-wall support). None of those appears anywhere in the citation record below.

1. Sourcing — and two material contradictions you must see before relying on this

My tooling is web-based; I was blocked before I could complete a direct query of the USPTO full-text search (patft) and Patent Center. The citation record below comes from two live sources, and they do not agree with each other. I am flagging this rather than silently reconciling it.

Two problems, stated plainly:

1. Claim-number contradiction. The 15‑claim set in the Google record (independent system claim reciting CCIS network + SCP + "separate dedicated private data network" + Internet interface + "multiple selectable protocol conversion modules," plus claims 14–15 to a "centralized messaging system") matches the abstract of the same-day sibling US 6,215,858 B1 — which patents.searchlight.law/doc/US6215858 reports as having 15 Claims / 12 Drawing Sheets. The Justia 11‑claim set (claim 1 = two switched telephone networks joined by an "Internet comprising multiple remotely spaced computer networks of diverse types … connectionless packet service") matches the Internet-embodiment claims. Either the Google retrieval is mis-attributed, or 6,285,745 genuinely issued with the 15‑claim set. I cannot resolve this without the grant copy. §102 claim mapping below is keyed to the 11‑claim set (consistent with the previously generated sections) and I flag where the 15‑claim numbering would instead control.
2. Citation-list contradiction. Google's 61‑entry list lacks J‑list items US 5,497,414 (Bartholomew), US 5,530,852 (Meske), US 5,557,659 (Hyde-Thompson), US 5,572,643 (Judson), US 5,581,596 (Hogan); and the J‑list lacks Google's US 5,008,906 (Reichwein), US 5,327,486 (Wolff), US 5,539,817 (Wilkes), US 5,583,920 (Wheeler), US 5,610,910 (Focsaneanu), US 5,724,355 (Bruno), US 5,729,594 (Klingman), US 5,742,670 (Bennett), US 5,768,513 (Kuthyar), US 5,805,587 (Norris), US 5,838,682 (Dekelbaum), US 5,881,131 (Farris). Also two number variants: US 5,400,303 (Justia) vs US 5,400,393 (Google), both attributed to Knuth; and US 5,259,026 (Johnson) appears only in Justia.

Consequence: the table in §2 is the union, with provenance marked. Anything marked (G only) or (J only) needs verification against the printed patent's front page.

Non-patent literature

3. §102 legal framework that governs this list (pre‑AIA)

The '745 patent is pre‑AIA (filed 1996‑02‑09), so the pre‑AIA §102(a)/(b)/(e) regime applies, with no AIA §102(d) "effectively filed" carryover for these citations as such.

• Critical date. Claims supported by the 1994‑12‑05 parents get a 1994‑12‑05 critical date. The Internet-embodiment and multimode-IP subject matter is new matter added in the 1996‑02‑09 CIP — so for claims 1, 4, 8 (and the 15-claim protocol-module claims) the operative date is 1996‑02‑09, not 1994‑12‑05. This matters enormously: US 5,530,852, 5,572,643, 5,608,786, 5,610,910, 5,631,948 and the whole post‑1996 block all post-date 1994‑12‑05 and would not be §102(b) art against the priority-date claims.
• §102(e) references. Documents with issue dates after 1996‑02‑09 can still be prior art only under §102(e), based on their filing dates (a U.S. patent granted on an application filed before the applicant's effective date). The §102(e) candidates in this list are: 5,608,786; 5,610,910; 5,661,790; 5,712,903; 5,724,355; 5,729,594; 5,742,670; 5,768,513; 5,805,587; 5,838,682; 5,881,131 — each must be checked against its actual filing date, which I could not retrieve for all of them in this session.
• §102(c)/(f) exclusions. US 5,631,948 (Bartholomew et al.) is a CIP parent of the same application family, same inventors, same assignee. It is therefore not available as §102(a)/(e) prior art against '745 (same inventive entity; and common ownership). Ditto the other family members (5,680,442; 5,661,782; 5,812,639) if cited. US 5,497,414 (Bartholomew) and US 5,712,903 (Bartholomew et al.) and US 5,881,131 (Farris et al.) share a co-inventor of '745 — check §102(e)'s "by another" requirement, which they may fail.
• Duty-of-candor note: several of these were cited by the Examiner, not the applicant (per Google's "Cited By" column), so any failure-to-cite theory premised on them is weak.

4. The single most important analytical conclusion

No cited reference is, on its face, a complete §102 anticipation of independent claim 1 or claim 8.

Claim 1 requires, in combination: (a) two separate switched telephone networks with COs/trunks/subscriber lines/terminals; (b) a centralized messaging network in each storing analog-originated messages in digital form; (c) an "Internet" = multiple remotely spaced, diverse, interconnected networks using a common protocol for connectionless packet service; (d) an addressable protocol-translating interface per messaging network; and (e) a transferred message carrying both a recipient-interface address and a destination subscriber-line address used by the destination messaging network to storage-address the message. Claim 8 mirrors these as method steps.

• The voice-mail references (Matthews '752/'906/'129, Lotito '081, Jones '110/'199, Misholi '926, Kepley '003, Von Meister '062) supply (a-partial), (b), (e)-analogues — but none discloses the "Internet"/TCP-IP connectionless interface (c)/(d).
• The Internet/packet references (Perlman '437, Meshi '852, Judson '643, Gordon '786, Focsaneanu '910, Bruno '355, Kuthyar '513, Norris '587, Dekelbaum '682) supply (c)/(d) — but not the two-network voice-mail architecture with subscriber-line-addressed storage (b)/(e).
• The combination is therefore an obviousness (§103) attack from the cited art, not an anticipation attack. The strongest §102(e) single-reference candidates to actually check against claims 1/4/8 are US 5,608,786 (Gordon) and US 5,610,910 (Focsaneanu); the strongest for claim 5/6/7 are Matthews '752/'906/'129, Lotito '081, and the AMIS specification.
• The only reference that squarely targets claim 4 (TCP/IP as the "common protocol") is Perlman '437, with the FNC Resolution as interpretive evidence.

If the granted claim set is in fact the 15-claim CCIS/SCP/protocol-conversion set (see §1, contradiction 1), the mapping shifts decisively to US 5,353,331 (Emery), US 5,387,186 (Wegner), US 5,386,467 (Ahmad), US 5,442,690 (Nazif), US 5,583,920 (Wheeler), US 5,712,903 (Bartholomew), US 5,768,513 (Kuthyar) for the CCIS/SCP/Intelligent-Peripheral and protocol-conversion limitations — and US 5,712,903 becomes the closest single reference, with a §102(e) date and a common-inventor (§102(e) "by another") defect to test. Settling the 11-vs-15 claim question is therefore the first thing to do on any invalidity project on this patent.

5. What I could not verify (stated explicitly, not papered over)

1. The total claim count and full claim text of US 6,285,745 — the authoritative text supplied in this file ends at "Background Art"; Justia shows 11 claims, the retrieved Google record shows a 15-claim set; they conflict. Resolve against the USPTO grant copy (patft / Patent Center) before any §102 chart.
2. Which citation list belongs to 6,285,745 — the 54-entry (Justia) vs 61-entry (Google) lists are inconsistent, not merely nested. Verify the front-page "References Cited" of the printed patent.
3. Issue/filing dates, titles and assignees for the ○-marked references — I did not retrieve each of the ~60 documents individually; my one-line glosses for those rows are not established and must not be quoted.
4. Direct USPTO database query — I was stopped before completing it. Recommended exact-string queries: 6285745 and 6,285,745 at https://patft.uspto.gov/ (References Cited / Front Page), https://patentcenter.uspto.gov/ (file wrapper), and https://assignmentcenter.uspto.gov/ — following the verification steps already recommended in the assignment and PTAB sections of this file.

Primary sources used in this section: https://patents.justia.com/patent/6285745 (11-claim set; 54-reference front page; AMIS + Jabbari NPL) · https://patents.google.com/patent/US6285745 (15-claim set; "Patent Citations (61)"; Jabbari + FNC NPL) · https://patents.google.com/patent/US6529592 and https://patents.google.com/patent/US8379531 (both cite US 6,285,745 B1) · https://patents.searchlight.law/doc/US6215858 (sibling, 15 claims / 12 sheets) · https://uspto.report/patent/grant/6285745.

I'll ground this obviousness analysis in the actual prior-art record for this patent. Let me pull the front-page references and verify a couple of the specification's cited references.

Verified: the specification's cited router patent is US 5,309,437 (Perlman/Koning, Digital Equipment, priority 1990-06-29) — the '745 text prints it as "9,309,437," an apparent typo I will flag rather than silently correct. Now let me check the front-page citations and contemporaneous Internet-voicemail art.

Two very useful hits. Now let me pin down the '745's own five front-page citations and check a second contemporaneous Internet-voicemail reference.

Obviousness Analysis — US 6,285,745 B1 under 35 U.S.C. § 103

0. Evidence base and integrity flags (read first)

What I used. (a) The authoritative full text you supplied (which, as noted in the earlier summary, ends at "Background Art" and contains no claims section); (b) the claim text reproduced from Justia in the earlier section — unverified beyond claim 11; (c) the prior-art references the '745 specification itself cites or admits; and (d) two contemporaneous references I verified by live search. Where I rely on (b) or (d), I say so.

Identifiers I am flagging rather than auto-correcting:

Governing law. Application filed 1996-02-09; the AIA first-inventor-to-file regime applies only to applications filed on/after 2013-03-16. So pre-AIA § 102/§ 103 govern, with KSR Int'l Co. v. Teleflex Inc., 550 U.S. 398 (2007), supplying the obviousness framework (its reasoning applies to pre-AIA cases). Prior-art status of later-filed patents turns on pre-AIA § 102(e).

A critical-date problem the patentee cannot escape (and it is the hinge of this whole analysis). The '745 is a continuation-in-part of Ser. Nos. 08/353,281 (1994-12-05), 08/371,906 (1995-01-12), 08/539,952 (1995-10-06) and 08/557,749 (1995-11-13). A CIP claim gets the parent's date only for subject matter supported in the parent under § 112. The AIN/SS7 embodiments (FIGS. 1–7) may well be supported by the 1994–95 parents. The Internet/TCP-IP embodiment (FIGS. 8–9) is the subject matter most likely added by the 1996-02-09 CIP. If so, claims 1, 4 and 8 (and dependents) are entitled only to 1996-02-09, and the window 1994-12-05 → 1996-02-09 becomes fully available prior art. Two of the four parents (08/539,952, 08/557,749) were themselves filed after the key reference below, so they cannot rescue the Internet claims either. I cannot verify from the text I have whether the Internet disclosure appears in the 1994-12-05 or 1995-01-12 parents; that is a document-comparison task against the parents' specifications and is the single most important factual check in this analysis.

1. The person of ordinary skill in the art (POSITA)

As of December 1994–February 1996: a bachelor's degree in electrical engineering or computer science (or equivalent) plus 2–4 years of experience in stored-program-controlled telephony or data networking; or a master's plus 1–2 years. Critically, the '745 sits at the junction of two mature arts, and the POSITA is the person who straddles them:

• Voice messaging — SMDI signalling, multi-line hunt groups, T1 (24-channel DS-1) digital voice trunks, mailbox/address data structures, message deposit/reply/redirect/delivery routines (Matthews; Jones; Misholi).
• Packet data networking — the Internet, TCP/IP, routers, bridges, datagram delivery and reassembly, address resolution (Perlman).

The '745 specification itself describes both arts at textbook level (it explains SMDI, T1, SS7 point codes, TCAP, and — in the FIG. 8–9 material — TCP/IP "taking care of the integrity" while "IP moves the data"). That is an admission of what the POSITA already knew.

2. The prior art of record

References the '745 specification itself cites as background (admitted art):

Verified contemporaneous art new to this analysis:

• US 5,608,786 — Gordon, "Unified messaging system and method," Alphanet Telecom Inc. — filed 1995-02-13, priority 1994-12-23, issued 1997-03-04, status "Expired due to Term" (Google Patents; RPX Insight). Gordon claims a system of commercial access providing computers, each with a bank of DID telephone lines to the PSTN and each connected to the Internet, where each subscriber is given an E-mail address, a fax telephone address and a voice mail telephone address, and where "messages stored for a subscriber in said associated computer are transferred using INTERNET from said associated access providing computer to one of the other commercial access providing computers." That is, in substance, PSTN-deposited voice mail forwarded mailbox-to-mailbox over the Internet. This is the most dangerous single reference to the '745's Internet claims, and it is not in the '745's citation set.

• Non-patent art evidenced in the field (surfaced in the IDS of US 8,838,074, so provenance is flagged): Yang, "INETPhone — Telephone Services and Servers on the Internet," Univ. of North Texas, Apr. 1995; Brachman et al., "Fragmentation in Store-and-Forward Message Transfer," IEEE Communications Magazine, vol. 26(7), July 1988; "The VMX Systems Product Reference Manual," May 1994. I did not independently verify these items; they are candidates to pull, not confirmed '745 prior art.

References that are NOT available as art against the '745: the Bell Atlantic CPS parents and sibling (US 5,812,639; the 5,680,4xx patent; US 6,215,858). To the extent they qualify only under § 102(e)/(f)/(g), pre-AIA § 103(c) disqualifies them because they were commonly owned by Bell Atlantic Network Services (obligation of assignment) at the time the '745 was made. They remain usable only as admissions about the state of the art.

3. Claim-by-claim obviousness

Claim 1 (system). Element mapping:

Claim 2 (destination network retrieves and conveys to a terminal on the identified line): Matthews' INQUIRY routine and automatic DELIVERY routine; Jones. Obvious.

Claim 3 (analog delivery): Matthews/Jones playback over POTS via CODEC; the spec says delivery occurs "as an audio voice message in the usual fashion." Obvious.

Claim 4 (the common protocol is TCP/IP): disclosed expressly by name in Perlman '437 and by Gordon's Internet-based exchange. This is the easiest claim in the set.

Claim 5 (voice messaging system with voice mailboxes tied to directory numbers of subscribing lines): Matthews '752/'906/'129 (mailboxes/"user's address"/RO message addresses keyed to telephone numbers); Jones; Gordon (voice mail telephone address).

Claim 6 (destination network has a database of assigned directory numbers, searched on message receipt; storage address depends on the search): the spec itself says the ISCP does this and that the STPs already hold "the 800 database and the credit card database, and … a further database for AIN. It is these databases which are utilized for the purposes of the present invention." That sentence is a naked admission that database-resolved routing/billing is old; the AIN/SCP art (AT&T 235-190-125, Weisser US 5,245,719) supplies the lookup.

Claim 7 (mailbox-to-mailbox transfer between originating and destination networks): Matthews' redirect/reply/forward; Jones' voice-mail networking (the spec's own background section describes guest mailboxes, central-switch networking software, and networked systems); Gordon '786 claim 1 transfers stored messages between access computers over the Internet.

Claim 8 (method): same combination. The added "in response to dialing a number … connecting that terminal to the first network's centralized messaging system" is Matthews' dial-in/dial-out VMS access and the spec's own "real or virtual directory number to trigger the service."

Claims 9, 10, 11: analog input at the CO (inherent in POTS/DID — Matthews, Jones, Gordon), analog delivery (as claim 3), and delivery responsive to a telephone call placed to the second network (Matthews' retrieval call; Gordon's retrieval "using either a telephone set … or using a computer and modem").

Combination that invalidates claims 1–11: Matthews '752/'906/'129 (messaging) + Perlman '437 (Internet/TCP-IP connectionless delivery through an addressable router/interface) + Gordon '786 (Internet transport of PSTN-deposited voice mail between messaging computers), optionally + AIN/SCP database art (claim 6). A leaner two-reference combination — Matthews + Gordon — reaches claims 1–5 and 7–11 without Perlman, with Perlman supplying the express "connectionless"/TCP-IP-hyphenation language for claims 1 and 4.

4. Why a POSITA would have combined them

1. The '745's own specification supplies the motivation. It states that networked voice-mail systems "must be of the same manufacture because there are no standards for communication between systems," and that work on AMIS was underway "in the hope that when AMIS standards are approved, they will form a common language." An explicit, art-recognized need to interconnect heterogeneous messaging systems, plus an express expectation that a common protocol would emerge, is the archetypal KSR rationale.
2. The specification states the reason to choose the Internet over the AIN. It concedes the Internet's advantage "that the Internet is presently operative on a world wide basis whereas interconnection of the existing AIN's of telephone operating companies has not yet been implemented over the entire United States … partially due to regulatory constraints and partially due to limitations in the common channel signaling systems of some telephone companies." A patentee's stated reason to substitute one known transport network for another is a § 103 motivation, not a rebuttal.
3. Predictable use of a known technique to improve a similar device (KSR). Voice mail is, by the specification's own admission, store-and-forward and not real-time: "the fact that the packets may not arrive at the destination in the same order as originated is of no consequence in that real-time voice communication is not involved." Packet-switched, connectionless, out-of-order-tolerant delivery is the natural transport for a store-and-forward messaging application; Perlman supplies the integrity half of the equation ("TCP keeps track of what is sent, and retransmits anything that does not get to its destination correctly"). The result is a combination of familiar elements according to known methods, yielding no more than predictable results.
4. Design incentives / market pressure. Eliminating distance-sensitive voice trunking for message delivery, exploiting underused signalling/Internet capacity, and reaching addressees regardless of the destination system's manufacturer are all recognized engineering and commercial objectives in the field.
5. Reasonable expectation of success. Both Perlman (TCP/IP encapsulates and reassembles arbitrary payloads across datagrams) and the '745's own admission that "the voice mail system is so designed as to inherently handle any translation necessary to communicate with the switching system in T1 … protocol" show that a POSITA would expect the interface to work. The '745's claimed "protocol-translating interface" is precisely the ordinary translation gateway the art already used.
6. Contemporaneous independent arrival. Gordon/Alphanet filed the same Internet-voicemail architecture on 1995-02-13 — roughly one year before the '745 CIP and only 18 days after the '745's earliest priority date. That is strong evidence the solution lay within the ordinary skill level rather than amounting to invention. (Simultaneous invention is not itself a Graham factor, but it is probative of the level of skill and of the predictability of the combination.)

5. Secondary considerations — and the one genuine patentability zone

No evidence in the record supports nexus-based secondary considerations. The patent expired 2014-12-05 ("Expired - Fee Related"), no litigation or PTAB proceeding exists (per the earlier sections), and no licensing attributable to claim scope is documented. The only candidate, long-felt need (the AMIS standards effort), cuts both ways: the need existed, but Gordon's intervening filing and the '745's own admission that a "common language" was expected show the need was being met concurrently by the ordinary artisan's routine use of TCP/IP — which is a weakness, not a strength.

The strongest nonobviousness argument available to the patentee lies outside the claims I can verify. The specification's distinctive contributions are: (i) public / "for hire" mailboxes enabling messaging to parties who are not voice-mail subscribers or Internet users; (ii) a reply-request indication carried with the message and billed to the originator; (iii) the 900-service question-and-response variant; and (iv) the express goal of "analog terminal internet access" — full Internet-side messaging with no computer, no Internet address and no Internet literacy required at the terminal. If claims beyond claim 11 (or claims I have not seen) recite those limitations with specificity, that is where an obviousness challenge is weakest, because Gordon's '786 presupposes subscribers with provisioned accounts. Claims 1–11, as reproduced, do not appear to capture that territory.

6. Bottom line and confidence

Claims 1–11 (the only claims available to me) are, on this record, obvious under pre-AIA § 103 over Matthews '752/'906/'129 (plus Jones and/or Misholi) in view of Perlman US 5,309,437 and Gordon US 5,608,786 — with AIN/SCP database art supplying claim 6. The strongest single knockout is US 5,608,786, which is outside the '745's citation set, is only 18 days younger than the '745's earliest priority date, and falls squarely in the 1994-12-05 → 1996-02-09 gap that the CIP's "Internet" subject matter most likely occupies.

Confidence: high on the prior-art content of Matthews, Jones, Misholi, and Perlman (all cited in the '745 itself, and Perlman independently verified); high on the bibliographic facts of US 5,608,786 (verified on two independent databases). Moderate on the § 103 legal conclusion, because it depends on (a) the actual text of claims after claim 11, which I could not obtain — the authoritative text you supplied has no claims section, and the Justia reproduction is truncated at claim 11; (b) the § 112 priority analysis for the Internet/CIP subject matter, which requires comparing the '745 specification against the four parent applications; and (c) claim construction of "Internet" and "addressable protocol-translating interface," for which there is no court or Board decision to rely on (per the earlier sections, the patent was never litigated or petitioned). I also did not verify US 4,837,798 or any non-patent item beyond those noted.

Recommended follow-up, in priority order: (1) pull the parents' specifications and diff them against the '745 to fix the effective filing date of the Internet claims; (2) pull the full front-page "References Cited" list for US 6,285,745 (Google Patents shows only a small citation set — consistent with the very short list the '745 itself cites); (3) pull the prosecution history for any § 103 rejection or amendment that distinguished the Internet transport, since that is where the patentee's own obviousness position will be recorded.
