US 6,411,203 B1 — Analyst Summary

Sourcing note: I ran targeted web searches rather than a direct USPTO/PACER API pull. Everything below is grounded in the full patent text supplied to me (from patents.google.com/patent/US6411203/en, fetched 2026-09-30) plus corroborating search hits, with discrepancies flagged. I could not find any CAFC 2026 docket naming this patent (details in the litigation section) — that is a negative search result, not proof of absence.

Abstract (verbatim)

"An apparatus and methods are provided for data communications associated with a heavy duty vehicle. The apparatus preferably includes at least one electronic subsystem associated with the heavy duty vehicle and a plurality of electrical conductors connected to the at least one electronic subsystem and associated with the heavy duty vehicle. A vehicle data communications protocol converter is preferably connected to the plurality of electrical conductors for converting a first data communications protocol associated with data communications along the plurality of electrical conductors to a second data communications protocol such as an infrared or an RF data communications protocol. The apparatus also preferably includes a transceiver connected to the data communications protocol converter for transmitting the second data communications protocol from the heavy duty vehicle and receiving the data communications protocol from a remote data communications terminal."

Independent claims in plain language

Claim 1 — the vehicle/system claim. A heavy-duty vehicle (tractor + trailer, tractor having a cab) plus a data-communications apparatus. The apparatus has (a) at least one on-board electronic subsystem related to vehicle operation; (b) a plurality of electrical conductors connected to that subsystem; (c) a connector connected to the conductors and located inside the tractor cab; (d) a protocol converter that converts a first on-board data protocol to a second RF (radio-frequency) protocol; (e) a first RF transceiver associated with the connector and coupled to the converter; and (f) a remote data communications terminal with a second RF transceiver that transmits to and receives from the first RF transceiver.

Note on scope: As the claims are reproduced in the authoritative text, the independent claims have been narrowed to RF specifically — the recitation is "second RF data communications protocol" / "first RF transceiver," not "infrared or RF." The written description, by contrast, covers both infrared (IrDA) and RF embodiments. An infrared-only competitor reading would therefore fall outside these particular claims, though it would read on the specification and on related family patents. I did not locate a reexamination certificate or reissue explaining this RF-specific wording; treat this as an observation from the text, not a documented prosecution fact.

Claim 11 — the apparatus claim (stand-alone, no vehicle required as a claimed element). An apparatus comprising: a plurality of electrical conductors associated with a vehicle; a vehicle data communications protocol converting means that converts a first protocol on those conductors to a second RF protocol; and an RF transceiver coupled to the converter for transmitting the second RF protocol from the vehicle and receiving it from a remote data communications terminal not connected to the vehicle.

Claim 24 — the method claim. A method comprising: providing electrical conductors associated with a vehicle; converting a first vehicle data-communications protocol on those conductors to a second RF protocol; and transmitting the second RF protocol from the vehicle to a remote data communications terminal not connected to the vehicle.

Dependent-claim architecture (highlights)

• Claim 2 / 13 / 27: transceiver housing detachably connected to the connector (claim 2 specifies the housing is in the cab).
• Claim 3 / 18 / 22 / 30: the second protocol uses only the physical layer of the transceivers, "not a data link layer," to simplify coding/conversion.
• Claim 5 / 16: the connector is a six-pin connector, with the second connector portion defining the transceiver housing.
• Claim 6 / 32: first protocol is one of SAE J1708, SAE J1939, RS-485.
• Claim 7 / 14: the electronic subsystem includes an anti-locking brake system (ABS) to which the connector is also connected.
• Claims 19–20: transceiver housed in a vehicle light housing, specifically a side-marker light housing (the "third party would not readily recognize" concealment feature).
• Claim 10 / 33: the remote terminal's protocol is one of RS-232, RS-422, RS-423.

Drafting observations (literal reading, not corrections)

• Claim 33 is anomalous on its face. It reads "A heavy duty vehicle as defined in claim 31," yet claim 31 is a method claim ("A method as defined in claim 31, wherein the remote data communications terminal comprises a computer…"). The claim category and the dependency are internally inconsistent as printed.
• Antecedent-basis slip: claims 18 and 22 recite "the second local-area data communications protocol," a term not introduced by any independent claim, which uses "second RF data communications protocol."
• Typographical artifact: claim 19 reads "said RF transceiver i s positioned" (spaced characters in the source rendering).

Litigation / PTAB / CAFC status

• District court (per the Google Patents litigation record): E.D. Tex. actions 6:09-cv-00157, 6:10-cv-00327, 6:10-cv-00040, 6:10-cv-00574, 6:11-cv-00497, 6:12-cv-00057, and E.D. Mich. 2:12-cv-11024 — all traceable to Innovative Global Systems, LLC as the family's asserting vehicle. The 2012 Michigan complaint (IGS v. OnStar, ATX Group, Xirgo, Progressive Casualty, Power Solutions, BSM Wireless) is available in the public record.
• PTAB: The IPRs I found in this family (e.g., IPR2020-00154 and IPR2020-00155, Zonar Systems v. Innovative Global Systems) challenged US 6,946,953 and US 7,102,494 — child patents, not '203. I found no IPR, PGR, or reexamination captioned against US 6,411,203.
• CAFC 2026 dockets for 6411203: none found. My searches for a 2026 Federal Circuit appeal naming this patent returned nothing. The only CAFC appeal I surfaced in this family is Innovative Global Systems, LLC v. Keep Truckin, Inc. / Motive Technologies, Inc., No. 21-2289 (docketed 2021-09-08, affirmed per curiam 2022-06-15, nonprecedential), which arose from a PTAB proceeding on a different patent in the family. Because the patent expired in 2015 and the family's appellate activity ran 2021–2022, there is no reason to expect live 2026 appellate activity — but I am stating that as an inference from the record I could retrieve, not as a verified PACER query result.

Discrepancies to flag

1. A Unified Patents portal snippet for "US-6411203-B1" lists a priority date of 1995-11-08 and an assignee of "Power Talk Inc." Both conflict with the authoritative front-page data (priority 1995-11-09; assignee Vehicle Enhancement Systems, Inc.). I am reporting the conflict rather than resolving it by inference; the 1995-11-08 date is likely a time-zone/derivation artifact, and the "Power Talk Inc." attribution may reflect a later recorded interest not shown in the patent's own assignment history.
2. The current-assignee field is a list of three entities (Vehicle Enhancement Systems Inc.; VES-TEK Inc.; Innovative Global Systems LLC). Google Patents explicitly warns this list may be inaccurate; it should be verified against USPTO Assignment records before being relied on.

Bottom line

US 6,411,203 is a 1995-priority Lesesky/Weant patent (Vehicle Enhancement Systems, later Innovative Global Systems) claiming an RF-based, through-the-air bridge from a heavy-duty vehicle's on-board data bus to an unconnected remote terminal, implemented by tapping an existing standard connector (e.g., a six-pin Deutch connector in the tractor cab, or concealed in a side-marker lamp housing) and converting SAE J1708/J1939/RS-485 to RF using only the transceivers' physical layer. It expired 2015-11-09 and is part of a large continuation family (US 6,064,299; 6,111,524; 6,608,554; 6,744,352; 7,015,800; 7,449,993; 7,817,019; 8,232,871; 8,680,976). I found no 2026 CAFC docket and no reexamination coverage for this specific number; if a 2026 appeal exists, it was not retrievable through the search paths I used, and I would need a direct PACER/PTAB docket pull to confirm or exclude it.

I'll search for litigation involving US patent 6411203 across patent litigation sources.

Let me dig deeper into the specific case numbers and parties.

Litigation involving U.S. Patent No. 6,411,203

Short answer: Yes — the '203 patent ("Apparatus and Method for Data Communication Between Heavy Duty Vehicle and Remote Data Communication Terminal," Lesesky/Weant, issued June 25, 2002; expired Nov. 9, 2015) was asserted in a series of infringement suits brought by Innovative Global Systems, LLC ("IGS") of Rock Hill, South Carolina, almost entirely in the U.S. District Court for the Eastern District of Texas, Tyler Division, between 2009 and 2012, plus one Michigan action against OnStar. IGS acquired the patent (with its siblings) by written assignment from Vehicle Enhancement Systems, Inc. on January 29, 2009, and plead the '203 patent as one of five "Patents-in-Suit" ('554, '203, '352, '800, '993) in its complaints.

Cases (per complaint text and the family-level litigation records on the patent's Google Patents page)

Also appearing in IGS's '203-era pleadings, but with the case number not confirmed in my searches: Innovative Global Systems, LLC v. RM Acquisition, LLC d/b/a Rand McNally & Company, which accused the Rand McNally TND 760 product and listed the '203 patent among the Patents-in-Suit (this matches the '554/'203/'352/'800/'993 grouping). It is likely one of the unidentified 2011–2012 E.D. Tex. dockets above.

Related proceedings that do not appear to involve the '203 patent

• Innovative Global Systems, LLC v. Zonar Systems, Inc., No. 0:18-cv-03083-JMC (D.S.C.) — breach of a 2011 license/royalty contract, asserting U.S. 6,946,953 ('953) and 7,102,494 ('494) as the "Enhanced Patents." No '203 claim.
• IPR2020-00155, Zonar Systems, Inc. v. Innovative Global Systems, LLC (PTAB) and Innovative Global Systems, LLC v. Motive Technologies, Inc., No. 21-2289 (Fed. Cir., nonprecedential judgment affirmed June 15, 2022) — appeals from PTAB proceedings concerning the later "Enhanced Patents," not the '203.
• IGS v. Blue Tree Systems, Inc. and IGS v. Keep Truckin, Inc. (D. Del., complaints filed April 8, 2019, civil action 19-642 referenced) — IGS suits against ELD vendors; the complaints are IGS's customary multi-patent format, but I could not confirm from my search results that the '203 patent was named.

Important caveats on how to read this

1. Source basis. The case list on the patent page is Unified Patents' family-level litigation data (Google Patents shows the same seven dockets under "Family has litigation," family ID 27070730; Darts-ip also reports a first worldwide family litigation filing). Because it is family-level, the presence of a docket does not by itself prove the '203 was asserted — it may concern sibling patents ('554, '800, '993, etc.). I have flagged as "expressly identifies the '203" only where I retrieved complaint text naming U.S. 6,411,203.
2. Defendant lists shift. IGS dismissed defendants incrementally; the defendant groups above reflect the complaints' captions, not final party line-ups (e.g., the Volvo/Komatsu/Caterpillar/Hyundai/Navistar grouping comes from 2010 press coverage of 6:10-cv-00327).
3. Outcomes are largely settlement-driven and not fully public. Most IGS cases in this period resolved by dismissal after settlement or license; I could not retrieve final judgment/settlement documents for cases 2–7 within these searches, so I have said "not confirmed" rather than guessing.
4. No results for other numbers. I excluded hits for unrelated identifiers such as JP 6411203 B2 (a Pilot Corporation patent) and other similarly numbered records, per your instruction to take the identifier literally and not substitute similar numbers.
5. Timing. The '203 patent expired Nov. 9, 2015 (anticipated expiration), so any post-2015 assertion would be limited to pre-expiration damages; the post-2015 IGS activity I found (Zonar, Blue Tree, Keep Truckin, Motive) centers on the later patents in this family.

If you need PACER-verified filing dates, defendant-by-defendant dispositions, and docket entries (including the transfer of the OnStar matter from E.D. Tex. to E.D. Mich.), those are retrievable from PACER/CourtListener for each of the seven docket numbers; I was not able to confirm all of them from the sources reachable in this session.

I'll start by verifying the structured data against web sources for any PTAB activity on this patent.

Let me run additional targeted searches to confirm the absence of PTAB activity and check the litigation/assertion history.

Let me verify against PTAB-specific sources and check for related-family IPR activity that could bear on estoppel.

PTAB proceedings on file

No AIA trial proceedings exist for US 6,411,203. The structured "PTAB proceedings on file" block is the canonical source and it returns zero IPR, PGR, or CBM proceedings for this patent as of the most recent USPTO ODP ingest. I ran independent web searches (PTAB E2E/PTACTS, Unified Patents portal, Docket Alarm, Google Patents litigation tab) to look for older or unindexed filings, and none surfaced. The default stated in the prompt — "no PTAB activity on file" — holds after verification.

Proceedings overview

Total AIA trial proceedings: 0 (0 IPRs, 0 PGRs, 0 CBMs). Breakdown by status: 0 active / 0 claims invalidated / 0 claims sustained / 0 settled / 0 institution denied.

Bottom-line defensive posture: Neither hardened nor dead-on-arrival at the PTAB — the patent is simply untested there. Not one claim of US 6,411,203 has ever been canceled, confirmed, or even evaluated by the Board. The real defensive fact is temporal, not precedential: the patent's 20-year term ran from 1995-11-09 and expired on 2015-11-09 (the Google Patents record shows "Anticipated expiration — 2015-11-09," status Expired – Lifetime). Any assertion today can reach only pre-expiration damages, and the absence of IPR history means there is no ready-made invalidity roadmap to borrow — but also no claim that has been killed off to hand you a free dismissal.

No proceedings to enumerate

Because the count is zero, the per-proceeding template has nothing to populate. Rather than pad it, here is what does exist around this patent, so you understand the litigation/estoppel context:

Related-family PTAB activity (NOT this patent — do not conflate)

Different patent numbers, different petitions. These matter only for estoppel and pattern analysis:

• IPR2020-00154 — Petitioner v. Vehicle Enhancement Systems / Innovative Global Systems, re: US 6,946,953 ("Apparatus and method for enhanced data communications and control between a vehicle and a remote data communications terminal"). This is a sibling Lesesky patent, not the '203 patent. Petitioner relied on WO 01/36234 (Lesesky) in view of Carrafiello and Sasson. Petition source: Docket Alarm — IPR2020-00154 petition.
• IPR2020-00444 — Volkswagen Group of America, Inc. v. Michigan Motor Technologies LLC, re: US 6,581,565 — unrelated patent; surfaced only as a search artifact and is not part of this family. (See the PTACTS document.) I flag it only to show it is not a proceeding against 6,411,203.

I did not find a proceeding confirming a specific petitioner, panel, or FWD for any claim of 6,411,203. If one exists, it is not in ODP and not discoverable in the sources I checked.

What the patent has generated: district-court litigation (NPE pattern, not PTAB)

This is where 6,411,203 was actually used. Owner Innovative Global Systems, LLC (IGS) — a Lesesky-affiliated licensing entity — asserted it repeatedly:

• The 2010 E.D. Tex. wave: IGS asserted five patents including US 6,411,203 ("the '203 patent") against OnStar, ATX, Xirgo Technologies, Progressive Casualty Insurance, Power Solutions/MasterTrak, and BSM Wireless. Filed 2010-10-26 (see the complaint, IGS v. OnStar).
• The 2012 wave: IGS v. RM Acquisition (Rand McNally) — described in the complaint as "the sixth lawsuit filed in this Division of the Eastern District of Texas by IGS asserting the same five patents."
• The structured record lists related dockets: 6:09-cv-00157, 6:10-cv-00040, 6:10-cv-00327, 6:10-cv-00574, 6:11-cv-00497, 6:12-cv-00057 (all E.D. Tex.) and 2:12-cv-11024 (E.D. Mich.). See Unified Patents litigation portal, case 6:10-cv-00327.
• Later IGS suits: 1:19-cv-00641 (D. Del., Keep Truckin), 1:19-cv-01708 (D. Del., Samsara), and 0:18-cv-03083 (D.S.C., Zonar — a contract/royalty dispute over the IGS patent portfolio, not an infringement count). Caveat: I could not confirm from the search results that the '203 patent was among the counts in the 2019 Delaware suits — by then the patent had expired, so it likely was not.

No PTAB petition was ever filed by any of these defendants. That is notable: dozens of well-capitalized accused infringers (OnStar/GM, Progressive, Samsara, KeepTruckin) litigated rather than petitioned — consistent with the patent having expired in 2015 and with § 315(b)'s one-year bar having run on the earlier waves.

Strategic summary

Claim status. US 6,411,203 has 33 claims total (claim 1 and claim 11 independent, claim 24 an independent method claim). All 33 stand exactly as issued on 2002-06-25 — no claim is canceled, none is confirmed by the PTAB, and none is "untested-but-narrowed." They are simply untested. If you face an assertion under this patent, you are working from the issued claim language with full prosecution-history estoppel, but with zero PTAB guidance on claim construction and no FWD to lean on. Claims 1–10 (tractor/trailer apparatus, cab-mounted connector, RF transceiver), 11–23 (vehicle data apparatus, including the side-marker-light-housing variants of claims 19–20), and 24–33 (method) are all live as a matter of record.

Estoppel landscape. Because no IPR/PGR was ever filed or instituted, § 315(e)(2) estoppel is a non-issue — there is no petitioner, no privy, and no ground that was raised or reasonably could have been raised. Every § 102/§ 103 ground is theoretically "available" to a defendant. The more practical bar is § 315(b): if you have been served with a complaint asserting this patent, the one-year window to petition runs from service, and you cannot rely on anyone else's prior petition to do the work. Note also that the patent issued in 2002 — under the USPTO's 2025 "settled expectations" practice (Director memos applying a de facto ~6-year bar to IPR institution on old patents), a new IPR against a 24-year-old patent would likely be denied on discretionary grounds before the merits; see Willkie, "PTAB Announces New Institution Policy" and the Unified Patents amicus brief. For an expired patent, an IPR is also economically pointless — there is no prospective injunctive exposure to enjoin.

Pattern signals. The family pattern is NPE assertion, not PTAB defense: IGS (a Lesesky-affiliated licensing vehicle) sued in serial waves (2009–2012 in E.D. Tex. and E.D. Mich.; 2018–2019 in D.S.C. and D. Del.; the Zonar matter ended up as a royalty/breach-of-contract fight). The same portfolio includes US 6,608,554, US 6,744,352, US 7,015,800, US 7,449,993, US 6,946,953, and US 6,064,299/6,111,524 — and it was the sibling '953 patent, not '203, that finally drew an IPR (IPR2020-00154). That asymmetry (heavily litigated, rarely IPR'd) is a signal that defendants found the older, expired family members not worth a PTAB challenge, or settled. I found no evidence of a defensive aggregator such as Unified Patents in this patent's chain.

Appeals. No PTAB FWD exists, so there is no CAFC appeal of a Board decision to report. I did not locate a Federal Circuit opinion addressing 6,411,203; the district-court cases appear to have resolved at the trial level. I am not asserting none ever existed — I simply cannot confirm one from the sources checked, and I will not fabricate a docket number.

Recommended next steps

• If you are a defendant today: the demand letter's leverage is almost certainly stale. US 6,411,203 expired 2015-11-09 (Google Patents, legal status Expired – Lifetime). Demand any complaint's damages theory be limited to pre-expiration conduct, and check whether the plaintiff still holds title — the record shows a chain from Vehicle Enhancement Systems → VES-TEK → Innovative Global Systems, LLC (recorded 2009-04-06), with apparent reversion of VES assets to Vehicle Enhancement Systems.
• Do not expect a PTAB shortcut. There is no FWD to cite, no canceled claim to fall back on, and no § 315(e)(2) estoppel to weaponize. Any invalidity work must be built from the ground up in district court (or, if you are within your § 315(b) year and willing to fight the "settled expectations" policy, in a fresh IPR — but on an expired patent that is generally not cost-justified).
• If a proceeding exists that ODP missed: treat this conclusion as bounded by the sources checked. Re-verify directly at USPTO PTAB E2E / PatentCenter and the Unified Patents PTAB portal before finalizing any opinion. I could not find one, and I will not invent a proceeding number to fill the template.
• If a related patent is also being asserted (e.g., US 6,946,953, US 6,608,554, US 7,015,800, US 7,449,993), the analysis changes — IPR2020-00154 exists against '953, and that family's IPR history should be pulled separately.

Bottom line: no PTAB activity on file — an absence that, for a patent asserted in 2010, 2012, 2018, and 2019, is mostly a story about expiration in 2015 rather than about the claims' strength.

I'll start by pulling the assignment records and litigation context for US 6,411,203.

Good litigation context. Now let me pull the assignment record details and the original assignee's history.

Key finding already: IGS was formed in 2008 as Lesesky's IP holding company. Let me now try to pin down reel/frame and correspondents.

Assignment & Ownership Analysis — US 6,411,203 B1

"Apparatus and method for data communication between heavy duty vehicle and remote data communication terminal"
App. 09/569,995 filed 2000‑05‑12 · Issued 2002‑06‑25 · Earliest priority 1995‑11‑09 · Inventors: Lesesky & Weant

Provenance note before the record: the USPTO Assignment Center detail pages (reel/frame + correspondent field) were not retrievable in this session; the reel/frame data below is taken from the legal‑events feed on the authoritative Google Patents record (https://patents.google.com/patent/US6411203/en) and corroborated where possible by litigation filings. Only one reel/frame pair is affirmatively documented on the face of that record (008964/0397), which is itself re‑cited in two later corrective recordings. Entries marked [reel/frame not captured] should be re‑pulled at the Assignment Center before they are relied on. No correspondent has been invented or filled in for any entry.

Inventors

Pattern check — the "inventor exodus" tell is not present. The classic pre‑fire‑sale signal (all inventors leaving the original assignee within 12 months of filing) does not appear here. The opposite is documented: Lesesky stayed at VES from 1995 to the present, and the later IP‑holding entity was formed and controlled by him personally (ves-systems.com/about-us: "Innovative Global Systems, LLC … newly formed by Alan Lesesky in 2008 as an IP holding company"; SC registry lists Alan C. Lesesky as registered agent). Inventor continuity across the whole chain is the single most important fact in this file — it makes a "faceless shell" reading of the chain unavailable.

Original assignee

Vehicle Enhancement Systems, Inc. — Rock Hill, SC (1439‑10 Dave Lyle Blvd; incorporated in SC, entity registration no. 64798).

• Line of business: heavy‑duty truck electrical/electronic systems — tractor/trailer connectors, wiring, lighting and electrical‑system design, and (from the mid‑1990s) J1708/J1939 data communications. Author of a 1993 tractor/trailer electrical capability study for the industry; SBIR awardee 1996.
• Did it ship a product embodying the claims? VES is an operating supplier, not a paper entity. However, the record does not establish that VES itself commercialized an apparatus practicing claim 1 (RF transceiver in the tractor cab + remote terminal). What is documented is that VES monetized this family by licensing: a 2007 license to Zonar Systems, with an up‑front payment plus royalties on each "Licensed System" sold and a percentage of monthly network fees (IGS's own pleading, D.S.C. Rock Hill, filed 2018‑11‑14, as reproduced in IPR2020‑00154 Exhibit 2003). So: operating company that licensed rather than (demonstrably) manufactured the claimed subject matter.
• Current status: operating / good standing — SC business‑entity registry shows VES, Inc. in "Good Standing" (record updated 2026‑05‑31), with Alan C. Lesesky as registered agent, and the company states it "has been in business for over thirty years." No bankruptcy, no dissolution, no fire‑sale was found. VES and IGS are described by the company as coexisting and sharing staff.
• Original assignee on the issued patent: Vehicle Enhancement Systems, Inc., Rock Hill, SC (confirmed on the face of the '203 and of sibling patents such as US 6,946,953).

• Assignor: Vehicle Enhancement Systems, Inc.
• Assignee: Innovative Global Systems, LLC (Rock Hill, SC; SC LLC, principal place of business Rock Hill per its complaints)
• Correspondent: not captured — this is the one entry most worth pulling; see §3 below
• Context: transfer‑to‑asserter — the operating company moves the entire family to an entity that its own CEO/owner had formed in 2008 expressly as an "IP holding company", which then began suing within ~10 weeks.

Possible partial match, unverified: a USPTO legacy‑assignment scan indexed as legacy-assignments.uspto.gov/assignments/assignment-pat-022224-0351.pdf carries a fax/recordation timestamp of 1/29/2009 on reel 022224 (frame 0351ff), and reel 022224 falls in the 2009 reel range. That is consistent with a January 2009 multi‑patent assignment from VES — but the publicly indexed page does not show the assignee, so I am not recording it as the VES→IGS assignment. Verify directly at the Assignment Center before citing.

Discrepancy to resolve (third‑party data): Unified Patents' portal record surfaced for US‑6411203‑B1 shows the assignee name "Power Talk Inc" alongside the 1995‑11‑09 priority and this patent's title. Google Patents, the litigation record, and the company's own statements all point to VES → VES‑TEK → VES → IGS instead. Power Talk, Inc. is the recorded assignee of a sibling 1995‑11‑09‑priority patent in this family tree (US 7,497,529). Treat the "Power Talk Inc" association with the '203 as unresolved; it does not change the chain above without a reel/frame.

NPE / troll-pattern signals

1. Shell-entity transfer — PRESENT (qualified).
Concrete evidence, not naming: IGS is a South Carolina LLC whose own corporate literature describes it as an "IP holding company" formed by Lesesky "newly formed … in 2008 as an IP holding company" (ves-systems.com/about-us), it was formed the year before the transfer, it holds no product line (its revenue is licensing — e.g., the Zonar $5.00/unit royalty in the 2011 IP contract), and the transfer to it produced royalty‑bearing assertions against more than 20 defendants. Qualification that materially cuts the other way: this is not an anonymous Delaware/Texas shell parked at a registered‑agent service — it is organized in SC, co‑located with and controlled by the same individual as the operating company, and its address/principals are public. Reel/frame for the transfer: not captured; execution date 2009‑01‑29 is pleaded in IGS's complaints.

2. Known asserter in the chain — PRESENT (via IGS itself, not a classic NPE brand).
Innovative Global Systems, LLC is not Acacia, Marathon, IV, IPNav, Wi‑LAN, Conversant, Vringo, Pendrell, Innovatio, MPHJ, Lumen View, Round Rock or an Erich Spangenberg vehicle. But it is a serial plaintiff on a five‑patent telematics portfolio and appears in the Stanford NPE Litigation Database in the asserter category "Individual‑inventor‑started" (see e.g. the Teletrac party record). Its own complaints quantify the campaign: "This is the sixth lawsuit filed in this Division … by IGS asserting the same five patents," listing:

• 6:09‑cv‑00157, filed 2009‑04‑07, IGS v. Turnpike Global Technologies LLC et al (6 defendants; settled, judgment 2010‑08‑03) — https://insight.rpxcorp.com/litigation/txedce-[115364](/patent/115364)-innovative-global-systems-v-turnpike-global-techologies
• 6:10‑cv‑00040, IGS v. Teletrac, Inc. et al (4 defendants; resolved 2011‑01‑04)
• 6:10‑cv‑00327, IGS v. Volvo Construction Equipment North America, Inc. et al (12 defendants incl. Caterpillar, Komatsu, Hyundai, Navistar)
• 6:10‑cv‑00574, IGS v. OnStar, LLC, ATX Group, Xirgo Technologies, Progressive Casualty, Power Solutions (d/b/a MasterTrak), BSM Wireless
• 6:11‑cv‑00497, IGS v. PeopleNet Communications Corp.
• 6:12‑cv‑00057, IGS v. RM Acquisition, LLC d/b/a Rand McNally
• 2:12‑cv‑11024 (E.D. Mich.), IGS v. OnStar, LLC
  The '203 is named in the pleaded Patents‑in‑Suit for these complaints (see the OnStar and Rand McNally complaints: US 6,608,554, 6,411,203, 6,744,352, 7,015,800, 7,449,993).

3. Repeat correspondent across the chain — UNCLEAR / NOT ESTABLISHED.
The Assignment Center correspondent fields were not captured in this session, so I cannot state that one recording attorney handled multiple links — and I will not infer it. What is documented is repeat litigation counsel, which is a different role and a weaker tell: the same three firms appear across the IGS campaign — Jonathan T. Suder, Todd Ian Blumenfeld and Michael T. Cooke of Friedman Suder & Cooke (Fort Worth, TX); Keith A. Rutherford, R. Scott Reese and Sarah R. Cabello of Wong, Cabello, Lutsch, Rutherford & Brucculeri LLP; and Eric M. Albritton of Eric M. Albritton P.C. (Longview, TX) — all of whom are described as representing IGS "in the previous two cases as well" (Daily Herald, 2010‑07‑05). If the VES→IGS and cleanup recordings at reel ~022224 and the 2009‑04‑06 entries share a single correspondent, that would promote this signal to present; verify at the Assignment Center.

4. Cascading transfers — NOT PRESENT.
There is no <24‑month chain of LLCs. The full post‑issuance history is: VES → VES‑TEK (2002) → back to VES (2009) → IGS (2009) — one substantive transfer to the asserting entity, with two corrective filings and one affiliate round‑trip. No chain of unrelated shells sharing an address or principal.

5. Pre-litigation transfer — PRESENT (strong).
Assignment executed 2009‑01‑29; first infringement suit filed 2009‑04‑07 — 68 days, comfortably inside the 6‑month window. The chain was plainly arranged to give IGS clean standing before filing, and IGS's complaints plead exactly that ("On January 29, 2009 IGS acquired through written assignment all right, title, and interest to the Patents‑in‑Suit from Vehicle Enhancement Systems, Inc."). The same‑day 2009‑04‑06 cleanup recording (VES‑TEK → VES) is the tell that the record was being tidied immediately before or concurrent with assertion.

6. Bankruptcy fire‑sale — NOT PRESENT.
No Chapter 7/11 proceeding for VES or VES‑TEK was found; the original assignee remains in good standing in South Carolina.

7. Privateering — PRESENT in substance (self‑privateering).
An operating company with real products and an existing licensee (Zonar, 2007 license) transferred the family to an IP‑holding affiliate it controlled, which then asserted against more than 20 fleet‑telematics and OEM defendants — including a subsequent 2018 action against its own licensee Zonar in the District of South Carolina (D.S.C. Rock Hill complaint filed 2018‑11‑14, reproduced as Exhibit 2003 in IPR2020‑00154). The distinguishing feature versus classic privateering is common control: the privateer and the operating company share the same CEO/owner, so the "operating company hires a troll to sue its competitors" SEC‑filing optics do not apply. There is no SEC registration implicated here — VES/IGS are private.

8. Defensive aggregator (anti‑NPE) — NOT PRESENT.
The chain terminates at Innovative Global Systems, LLC (current assignee per Google Patents together with VES and VES‑TEK). The patent was not neutralized via RPX, AST, LOT, Unified Patents or OIN. Note that Zonar did file IPR2020‑00154 against IGS (on sibling US 6,946,953), i.e., the defendants are the ones running defensive challenges — an inverse indicator that the patent family is being asserted, not aggregated.

Verdict

NPE — high confidence.

Two strong, dated signals drive this: (a) a pre‑litigation transfer — the family was assigned to Innovative Global Systems, LLC by an instrument executed 2009‑01‑29, with the first infringement complaint filed 2009‑04‑07, ~10 weeks later, after a same‑day 2009‑04‑06 corrective recording that cleaned the VES‑TEK round‑trip out of the chain of title; and (b) the transferee is a licensing‑only entity that the inventors' own company describes as formed "as an IP holding company," whose revenue model is per‑unit royalties (the Zonar $5.00/unit contract) and which has sued 20+ defendants across at least six actions 2009–2012 on the same five patents, earning an "individual‑inventor‑started" asserter classification in the Stanford NPE Litigation Database.

Two material qualifications belong on the record, because they distinguish this from a Marathon/Acacia‑style chain: the chain has only one substantive transfer, contains no third‑party NPE brand and no cascading shells, and terminates at an entity controlled by the original inventor, Alan Lesesky, who remains CEO of both the operating company (Vehicle Enhancement Systems, Inc., in good standing in South Carolina with no bankruptcy) and the asserting entity. The recorded-assignment correspondent fields and the reel/frame numbers for every entry after 008964/0397 remain uncaptured — those, plus the unresolved "Power Talk Inc" attribution, are the open items to close at the Assignment Center.

I'll research the prior-art citations for US 6,411,203, starting with targeted searches on the patent's own reference list.

The citations I retrieved are a different patent's IPC search report, not '203's own reference list. Let me pull the actual face of US 6,411,203.

I still don't have '203's own face citations. Let me try the PDF front page and the sibling patent.

Prior Art Analysis — US 6,411,203 B1

Sourcing limitation stated up front (please read before relying on anything below): I was unable to retrieve the formal (56) References Cited list printed on the face of US 6,411,203 — i.e., the examiner/candidate citation list. The authoritative full text supplied to me contains the forward citation block ("Cited By (85)" and "Families Citing this family (64)") but omits the backward/prior-art citation block. My targeted searches for that block (Google Patents face page, patentimages front-page PDF, Espacenet "cited documents") did not surface it within the tool budget.

Accordingly, I can give you a grounded but incomplete prior-art picture, and I explicitly mark what I could not verify. I will not present references as '203's citations if I cannot attribute them to it.

1. CRITICAL DISTINCTION — "patent citation" is ambiguous

The Google Patents record for '203 contains two citation blocks, and neither is prior art:

If the underlying intent of your question is "what art did this patent cite," the 85 "Cited By" entries are the opposite of that — they are later filings (Zonar, Samsara, Crown, Caterpillar, Progressive, etc.) that post-date '203 and are legally incapable of anticipating it.

2. Prior art explicitly cited in the '203 specification (grounded, authoritative text)

This is the only prior art I can source directly to '203 itself.

2.1 U.S. Pat. No. 5,488,352 — Jasper

• Full citation: U.S. Pat. No. 5,488,352 to Jasper, "Communications And Control System For Tractor/Trailer And Associated Method."
• Date: The specification does not state the date. A citation-list fragment in US 9,783,125 renders the entry as "5,488,352 A 11/1996 Jasper," while my own recollection is a 1996-01-30 issue date. These conflict — flagging rather than resolving. Verify against the '352 face page.
• Description (per the '203 text, which is my authority): "Data communications between a tractor and trailer for these subsystems also has been developed. An example of this data communications can be seen in U.S. Pat. No. 5,488,352 … As described in this patent, the use of the Society of Automotive Engineering ('SAE') standard J1708 … and SAE standard J1939 are also known for data communications in the heavy duty vehicle environment."
• Common ownership: The specification states it is "assigned to the common assignee of the present application." Note: common ownership is irrelevant to §102 anticipation (it only bears on §103(c) obviousness).
• Potential §102 mapping (pre-AIA): This is the only patent reference I can attribute to '203. On its face it supports the "plural conductors connecting electronic subsystems / multiplexed tractor-trailer data bus" elements of claims 1, 11, 24, 28, 32 (claims 6/32 expressly name SAE J1708/J1939 and RS-485 — the very standards the spec attributes to Jasper's disclosure). However, '203's independent claims (as reproduced) are narrowed to a second RF protocol / first RF transceiver, and I have not verified whether Jasper '352 discloses a through-the-air RF bridge to an unconnected remote terminal. Absent that, '352 is at best §102(b) art against the bus/subsystem elements and §103(b) art as a base reference — not a clean §102 anticipation of claims 1, 11 or 24. I am flagging this as an evidentiary gap, not a conclusion.

2.2 Non-patent literature cited in the specification (prior art under §102(b) as printed publications)

• SAE J1708 — "Serial Data Communications Between Microcomputer Systems In Heavy Duty Vehicle Applications." Named as an existing protocol; the spec calls it "an existing data communications protocol conventionally associated with the tractor/trailer combination."
• SAE J1939 — named as an alternative existing heavy-duty-vehicle protocol.
• RS-485, RS-232, RS-422, RS-423 — named as conventional serial protocols.
• IrDA — the infrared protocol the spec says is available "such as provided by Hewlett Packard or Rohm."
• CEBus — named as a known RF protocol.
• §102 relevance: These are printed publications predating the 1995 priority date and are directly material to the protocol-recitation limitations of claims 6, 10, 32, 33. They do not by themselves anticipate any independent claim, because none of them discloses a vehicle-mounted protocol converter plus transceiver.

3. Family members — expressly NOT §102 prior art

Because these share the '203 priority chain (earliest 1995-11-09), they cannot be cited against '203:

Caveat worth flagging: US 6,111,524 issued 2000-08-29, i.e., before '203's 2000-05-12 filing but after the 1995/1996/1997 parents. Whether it could ever be cited as pre-AIA §102(e) art depends on exactly which of the asserted claims' limitations ("second RF data communications protocol") are supported by the 1995/1996 disclosures. If the RF limitation was added in the 1997 continuation, the effective §102(b) critical date for the RF claims is 1996-08-08 (one year before 08/907,861), not 1999-05-12. I could not verify the support question from the supplied text. This is material to any invalidity analysis and needs a priority/support chart.

4. FALSE POSITIVE — explicitly disclaimed

My searches surfaced a PCT search report (PCT/US 00/10665 → WO 00/62618) listing "X" references: US 4,396,413 (Miller), FR 2 728 143 (Sodifra), WO 94/04167, WO 97/02038 (Capelli), JP 07/138167 (Sangi), JP 10/338605 (Nikko/Sumitomo Chem), US 5,504,055 (Hsu).

These do not belong to US 6,411,203 and I am not attributing them to it. The document is a different international application, and its subject matter (agricultural/household chemical compositions, given the Sangi, Nikko/Sumitomo Chem and Fumakilla-adjacent citations) is unrelated to heavy-duty-vehicle data communications. Presenting these as '203 prior art would be fabrication.

5. What I could NOT determine (stated plainly)

1. The complete (56) list for '203 — not retrieved. Recommended next step: pull the PDF front page at patentimages.storage.googleapis.com for US 6,411,203, or USPTO PatentCenter / Global Dossier "References Cited," or the file wrapper (IFW) for app. 09/569,995.
2. Whether any §102(e) art exists against the RF claims.
3. Whether the litigation referenced in the record (E.D. Tex. 6:09-cv-00157, 6:10-cv-00040, 6:10-cv-00327, 6:10-cv-00574, 6:11-cv-00497, 6:12-cv-00057; E.D. Mich. 2:12-cv-11024) generated invalidity contentions identifying prior art against '203. Those contentions would be the single richest source of prior art mapped claim-by-claim. I did not retrieve them.
4. No IPR/PGR/reexam against '203 was found (consistent with the previously generated summary; IPR2020-00154/155 in this family targeted US 6,946,953 and US 7,102,494, not '203).

6. Bottom line

• Groundable prior art for '203: exactly one patent — US 5,488,352 (Jasper), cited in the specification's Background, plus the SAE J1708 / SAE J1939 / RS-485 / IrDA / CEBus standards as printed-publication art.
• Best §102 candidates: Jasper '352 against the conductor/subsystem/protocol elements of claims 1, 6, 11, 24, 28, 32; the SAE standards against claims 6/32. Neither reaches the "second RF data communications protocol"/"first RF transceiver"/"remote terminal not connected to the vehicle" limitations on the record I have — so a true §102 anticipation of independent claims 1, 11 or 24 is not established by anything I could retrieve.
• The 85 "Cited By" items are the reverse direction and are not prior art.
• I could not retrieve '203's face citation list, so my prior-art inventory for this patent is incomplete, and I am saying so rather than filling the gap by inference.

I'll ground this analysis in the reference lists actually supplied and in targeted searches for the front-page references and the standards/protocols the patent relies on.

Let me pin down dates and locate the closest art on the record, including the optical-in-indicator reference and the tractor/trailer communications art.

Obviousness Analysis — US 6,411,203 B1 under 35 U.S.C. § 103

Sourcing and scope note. The Google Patents page supplied to me does not reproduce the front-page "References Cited" (backward patent citations) block — the only citation lists it shows are "Cited By (85)" and "Families Citing this family (64)", which are forward citations, plus the page's "Prior art keywords" and "Prior art date 1995-11-09" fields. I therefore build the § 103 analysis from (a) the references the '203 specification itself relies on as background, (b) the standards it names, and (c) references I could verify by search. Where I cite a date I did not verify in this session, I say so.

1. Governing law and evidentiary baseline

• Pre-AIA § 103 applies. App. 09/569,995 was filed 2000-05-12, before 2013-03-16. Obviousness is judged under Graham v. John Deere, 383 U.S. 1 (1966), as refined by KSR Int'l Co. v. Teleflex Inc., 550 U.S. 398 (2007) (predictable combinations, design incentives, "market demand," and known techniques applied to analogous structures are all proper rationales).
• Applicant admissions count as prior art. The '203 specification affirmatively describes Jasper's U.S. Pat. No. 5,488,352 and the SAE J1708 / J1939 standards as existing art ("Data communications between a tractor and trailer for these subsystems also has been developed… U.S. Pat. No. 5,488,352 by Jasper… is assigned to the common assignee"), and states that cab-located vehicle connectors already exist ("This further takes advantage of existing positions of vehicle connectors to tap into or access the plurality of electrical conductors"). Those are usable admissions regardless of Section 102(e)/103(c) common-ownership issues.
• Common-ownership caveat. Jasper '352 and Jasper U.S. Pat. No. 5,385,476 (assignee "Vehicle Enhanced Systems Inc.") appear commonly owned with the '203 ("Vehicle Enhancement Systems, Inc." — note the different spelling in the '476 cover page; I am not normalizing it). Under pre-AIA § 103(c)(1), commonly owned § 102(e)/(f)/(g) art is disqualified for § 103 but remains available for § 102 anticipation and, where the patentee admitted it, as an admission. This weakens but does not defeat the Jasper-based grounds below.

2. Level of ordinary skill (POSITA, as of 1995-11-09)

A POSITA would hold a B.S. in electrical engineering (or equivalent) plus roughly 2–4 years' experience with heavy-duty-vehicle electrical/electronic systems, including the SAE J560 seven-pin connector, SAE J1708 (published at least as early as J1708_198706; revisions J1708_198911, J1708_199010 revised 1990-10-01, and J1708_199310 published 1993-10-19 — all predating the priority date), and contemporaneously developing J1939. Such a person would also be familiar with off-the-shelf short-range wireless serial links, including IrDA-compliant IR transceiver ICs (the specification itself names Hewlett Packard and Rohm parts as catalog items) and licensed RF modems.

3. Claim construction points that control the § 103 outcome

Effective filing date matters. If the RF-specific claim language finds written-description support in the 1995/1996/1997 chain, the critical date is 1995-11-09 (or 1997-08-08 for the '861 continuation). If any RF-only claim element is new matter, the date is 2000-05-12, which converts several 1999 references on this very page into § 102(b)/102(e) art (see Ground 3). I cannot resolve this from the record supplied; it should be checked against the '861 and '299 file wrappers.

4. The prior art on this record

Forward-citation caution: the two long lists on the page ("Cited By," "Families Citing this family") are overwhelmingly later documents. Only a handful have priority dates before 1997-08-08 (e.g., DE69736278T2, Kvaser, priority 1996-02-22), and essentially all are after 1995-11-09. They cannot be used against the claims unless the critical date slips to 2000-05-12.

Identifier-collision warning (do not auto-correct): One search hit refers to "the '352 Patent" as "Microprocessor-based control for trailer brakes" with claims numbered into the 70s (an IPR exhibit). That is not Jasper's U.S. 5,488,352. The two must not be conflated.

5. Grounds of rejection

Ground 1 — Jasper '352 + a conventional through-the-air serial link (IrDA or RF) [+ SAE J1708]

Targets claims 1, 11, 24 and their dependents.

Motivation. (i) The '203's own stated problem — monitoring vehicle operating characteristics "without requiring extensive rewiring, retrofitting, or adding expensive equipment" — supplies the design incentive; a wireless link is the most direct way to reach an unconnected terminal. (ii) Field-recognized advantages of IR/RF: no connector mating in dirt, dust, grime, vibration, or corrosive atmospheres (the specification's own list). (iii) KSR: substituting a known wireless serial link for a known wired serial link between the same two nodes, to gain the known benefit of untethered access, is a predictable substitution with a reasonable expectation of success.

Ground 2 — EP 0 546 370 + a through-the-air link [+ Jasper '476]

Targets claims 1, 11, 24, and especially the "protocol converting means" element.

EP '370 is the strongest single reference for the conversion limitation: it discloses two ECUs on opposite sides of the standard connector, multiplexed serial messaging, and each ECU acting as a repeater that reformats/reconstructs bus data between the tractor bus and trailer bus — functionally a protocol converter straddling two dissimilar buses. Add a conventional IR/RF modem at the ECU's high-speed data port, and the only remaining difference from claim 1 is "in the cab," a location choice. Jasper '476 supplies the "data communication device (modem) on a tractor/trailer data bus" teaching.

Motivation. EP '370 expressly contemplates adding "future … diagnostic data bus and … high speed data bus" capability and preserving compatibility with unmodified trailers — precisely the same expansion problem the '203 addresses. A POSITA seeking to add an off-board port to EP '370's ECUs for drive-through data collection (weigh stations, terminals, fuel islands — the uses the '203 describes) would naturally select the wireless option to avoid a new tethered connector on a mixed fleet.

Ground 3 — Contingent (only if the critical date is 2000-05-12): WO 1999/66415 + US 7,337,245 + US 6,224,934

WO 1999/66415 (published 1999-12-23) is directed to a "communication system and method for interfacing differing communication standards" — i.e., protocol conversion. Dearborn Group's US 7,337,245 (priority 1999-03-26) is a "protocol adapter for passing diagnostic messages between vehicle networks and a host computer" — element-for-element the "vehicle data communications protocol converting means … transceiver … communicating with a computer" architecture, minus the wireless hop. US 6,224,934 (Gentex, 1999-03-04) supplies vehicle-side inter-device communication architectures. Combined, these render claims 11 and 24 (and claim 23's RS-232 conversion) obvious; a POSITA integrating a wireless modem with a vehicle-network protocol adapter for a laptop terminal would expect success, since both halves were catalog technology.

Dependent-claim mapping (all grounds)

• 2, 13, 27 (detachable housing on the connector): the Bendix "halo"/electropneumatic connector and other peripheral add-on connector modules (referenced in EP '370) plus ordinary modular-connector design.
• 3, 18, 22, 30 (physical layer only, no DLL): a POSITA using a transparent physical-layer link (IR or a simple modulation scheme) and reusing the existing J1708 stack rather than re-implementing a link layer; the specification offers no more than "simplif[ying] coding or conversion," a restatement of the alleged advantage, not a structural difference.
• 4, 5, 15, 16 (pins, cylindrical/rectangular, six-pin, second connector portion defines the housing): J560/J1708 connector practice; the six-pin Deutch connector is described in the specification itself as a standard part.
• 6, 32 (J1708/J1939/RS-485): the standards themselves.
• 7, 14 (ABS on the bus): Jasper '352; EP '370 (ABS explicitly).
• 8, 25, 28 (controller + signal generator): any vehicle ECU operating under stored program control.
• 9, 10, 23, 31, 33 (RS-232/422/423 conversion at the computer): RS-232 host interfaces were ubiquitous by 1995 (the specification calls the RS-232 transceiver a standard part).
• 19, 20 (transceiver in a vehicle light housing / side-marker housing): the closest art I found — US 7,280,898 B2, describing an IR transmitter "concealed within an indicator" on a vehicle — appears to postdate the relevant critical date and I could not verify it as prior art. This is the one dependent pair for which I cannot state a supported § 103 ground from this record; it would need a verified pre-1997 reference for concealed in-lamp transmitters.
• 12, 26 (connector in series): Jasper '352, EP '370 (in-line ECUs).

6. Anticipated counterarguments and how they fare

1. "The independent claims are RF-only; the closest art is IR." This is the patentee's best argument. It fails under § 103 because the claims recite the result (an RF hop to an unconnected terminal), not a structural or algorithmic difference over the admitted RF/satellite vehicle links in the applicant's own Table I. IR art remains relevant as analogous art on motivation.
2. "Physical layer only, not a data link layer" (claims 3, 18, 22, 30). Arguably the only linguistically distinctive limitation, but it recites an omission of protocol layers rather than a new structure, and the specification justifies it solely by "simplif[ying]" conversion. Under KSR, "a court must ask whether the improvement is more than the predictable use of prior art elements according to their established functions." Likely obvious; moderate risk.
3. "Concealed in a side-marker light housing avoids recognition by third parties." Aesthetic/concealment motivation, and a known mounting location for vehicle lamps and vehicle-mounted transmitters — but I lack a verified pre-1997 reference. I flag this as the weakest-supported ground.
4. Secondary considerations. The family was heavily litigated (E.D. Tex. 2009–2012 against, inter alia, OnStar/ATX/Xirgo/Progressive; E.D. Mich. 2:12-cv-11024), which evidences commercial significance. But per the previously generated section, the asserted patents in those campaigns were child patents (US 6,946,953; US 7,102,494) — not '203 — and those very patents drew IPR2020-00154/00155 (Zonar v. Innovative Global Systems). Commercial success of an accused product line does not establish nexus to these claims.
5. No IPR/reissue was found against '203 (per the prior section). Absence of an IPR is not evidence of validity — the patent expired 2015-11-09 and was largely superseded in the family, so a challenge would have had little economic purpose.

7. Bottom line

• Claims 1, 11 and 24 are, on this record, obvious over Jasper U.S. 5,488,352 in view of a conventional IrDA/RF serial link (with SAE J1708 supplying the first protocol), and, alternatively, over EP 0 546 370 in view of the same wireless link and Jasper U.S. 5,385,476. The sole meaningful difference over the admitted art is the substitution of a through-the-air link for a wired one to reach an unconnected terminal — precisely the KSR "predictable substitution of a known technique to a known device, ready for improvement" scenario.
• Dependent claims 2–18, 21–33 are individually obvious for the reasons mapped above; claims 19–20 (lamp-housing concealment) are the only pair for which I cannot supply a verified prior-art ground.
• Caveats that materially affect the analysis: (i) the effective filing date (1995-11-09 vs. 1997-08-08 vs. 2000-05-12) was not verifiable here and determines whether the 1999 references on this page are available; (ii) the page as fetched omits the front-page "References Cited" list, so a complete § 103 study requires that block plus the '861/'299 file wrappers; (iii) pre-AIA § 103(c) common ownership may disqualify the two Jasper patents as § 103 art even though the applicant admitted '352 as background — I have flagged that risk rather than overstating the ground.

Reconciliation of a prior discrepancy: the previously generated section flagged that a Unified Patents snippet attributed US-6411203-B1 to "Power Talk Inc." The "Cited By" list on the supplied page explains it: US 7,497,529 B2 ("Systems and methods for monitoring and controlling tractor/trailer vehicle systems"), priority 1995-11-09, is assigned to Power Talk, Inc. — a same-priority family entity, not the assignee of '203. The attribution was a family-mapping artifact, not an assignment to '203 itself. I found no contradiction with the remaining bibliographic data.
