US Patent 6,211,907 B1 — Analyst Summary

Bibliographic data (grounded in the patent text and USPTO/Google Patents family data)

Abstract (as issued)

A system for gathering, analyzing and storing information for motor vehicle theft and vandalism investigations. An on-board secure vehicle mounted surveillance system operable whether the vehicle is on or off, having a video camera generating video signals of an incident proximate the vehicle, an audio device, a motion sensor to activate the system, and lights activated by the system to illuminate the viewed area. Video signals are digitized into a synchronized data file carrying a unique vehicle identification and a time indicator, along with other input data such as audio. The file is encrypted and stored on a large-capacity, code-accessible device or transmitted via a transceiver in real time to authorities and/or an off-vehicle storage site. Once written, the encrypted file cannot be altered or corrupted, decrypted without the encryption key, or accessed without the access authorization code. The stored data file can be down-loaded for use as evidence.

Independent claims — plain-language overview

The patent has three claims that are independent in form: claims 1, 26, and 33 (claims 2–25 depend from claim 1; claims 27–32 and 34–50 depend from claim 26). Note that claim 33 does not expressly reference claim 26, so on a literal reading it is a separate independent method claim, not a dependent one.

Claim 1 (system claim) — An on-board, secure, vehicle-mounted surveillance system with four elements:

• (a) at least one video camera that monitors both the interior and the exterior of the vehicle and generates video signals of an incident proximate the vehicle;
• (b) a recording device that captures and securely stores those video signals and has "coded access";
• (c) a code that provides coded access to that recording device; and
• (d) "means for down loading said video signal from said coded access recording device."

Claim-construction note (litigation history): In Evicam Int'l, Inc. v. Enforcement Video, LLC (E.D. Tex. 4:16-cv-105), the parties agreed "download/downloading" means "transferring from one device to another over a wired or wireless network," and the court construed the "means for down loading said video signal" limitation as a means-plus-function term with structure interface 36, transceiver 39, interface 43, and equivalents. In the parallel PTAB institution decision (IPR2017-00051), the Board likewise treated the limitation as presumptively means-plus-function and agreed with Petitioner that only "transceiver" was a corresponding structure among those proposed.

Claim 26 (method claim) — A method for secure surveillance of incidents involving vehicles, comprising: (a) activating an on-board secure vehicle-mounted surveillance system having at least one video camera that generates video signals of an incident proximate the vehicle; (b) generating that video signal; (c) storing the video signal on a secure, large-capacity, code-accessible device; and (d) accessing the stored video signal by means of the access code.

Claim 33 (method claim) — Recites the same general method steps as claim 26 but adds the limitation that lights are mounted on the exterior of the vehicle and are facing toward the interior of the vehicle. (Note: claim 32, which depends on claim 26, separately recites lights mounted on the vehicle exterior.)

Litigation and PTAB history (searched)

• Evicam International, Inc. v. Enforcement Video, LLC d/b/a WatchGuard Video — E.D. Tex., Case No. 6:15-cv-01043 (filed Nov. 24, 2015), transferred to the Sherman Division as 4:16-cv-00105-ALM.
  • Asserted claims of the '907 patent: claims 3, 8, 13, 18, 19, 22, 24, and 27.
  • On June 5, 2017, Judge Mazzant denied WatchGuard's summary-judgment motion of § 101 invalidity (Alice step two found an inventive concept), and separately denied WatchGuard's § 102/§ 103 invalidity motion (genuine issues of material fact remained as to whether Swanson, Schofield, or both anticipated or rendered obvious the claims).
  • July 14, 2017 jury verdict: no infringement, and the asserted '907 claims invalid. Agreed Amended Final Judgment entered Aug. 11, 2017 — claims 3, 8, 13, and 19 held not infringed, the asserted claims held invalid, and both parties expressly waived all rights to appeal (no post-verdict motions, no appeals).
• IPR2017-00051 (Enforcement Video, LLC v. Evicam International, Inc.) on U.S. Pat. 6,211,907 — instituted by the Board on Mar. 7, 2017 (institution decision discusses the "means for down loading" means-plus-function issue). The parties filed a Joint Motion to Terminate on Aug. 18, 2017, based on a settlement in which Evicam granted WatchGuard a covenant not to sue on the '907 and '013 patents in exchange for termination of the IPRs. The '907 IPR therefore ended in settlement/termination without a final written decision on the merits.
• IPR2017-00245 (on related U.S. Pat. 6,950,013, "Incident recording secure database") — also terminated by settlement; refund notice issued June 25, 2018.

CAFC 2026 docket search — negative result / uncertainty

I performed targeted searches for a Federal Circuit appeal or 2026 CAFC docket entry naming patent 6,211,907, and found no results. This is consistent with the record above: because the Agreed Amended Final Judgment expressly waived all appeal rights and the IPR terminated by settlement before any final written decision, there is no apparent path that would have produced a merits CAFC appeal of the '907 patent. The patent itself expired (anticipated expiration) on 2018-06-01.

Uncertainty caveats I want to flag:

• I could not run a direct, comprehensive query against the live CAFC docket system or PACER/PTAB docket APIs in this session; the negative 2026 result reflects the absence of any indexed public result for "6211907" combined with 2026/CAFC, not an exhaustive docket check.
• One search result (the Agreed Amended Final Judgment) truncates the list of claims found invalid — the visible text confirms the jury found no infringement as to claims 3, 8, 13, and 19 of the '907 patent and found "the asserted claims" invalid, but the full enumerated list of invalid claims was not fully captured in the retrieved excerpt.
• The user-supplied current date (April 26, 2026) differs from the date I was given at system level (2026-09-30); this does not affect any of the patent data above, which is historical.

Litigation Involving U.S. Patent No. 6,211,907

Based on my searches of Justia, Docket Alarm, Unified Patents/PTAB records, the Google Patents family/litigation tab, and law-firm case reports, I identified one district-court litigation and one related PTAB proceeding involving the '907 patent. I did not find any other defendants, any Federal Circuit appeal, or any ITC action on this patent. All searches were run on the exact number 6,211,907.

1. Evicam International, Inc. v. Enforcement Video, LLC d/b/a WatchGuard Video

Procedural history / key rulings (all involving the '907 patent):

• Claim construction (Oct. 14, 2016 hearing; opinion Nov. 2016): Court held the preamble "on board secure vehicle mounted surveillance system" was limiting; agreed constructions included "means for down loading said video signal" = "interface 36, transceiver 39, interface 43, and equivalents" and "download/downloading" = "transferring from one device to another over a wired or wireless network."
• Nov. 8, 2016: Court granted WatchGuard leave to supplement its invalidity contentions.
• June 5, 2017: Court denied WatchGuard's motion for summary judgment of invalidity of the '907 patent over Swanson and Swanson/Schofield.
• June 5–7, 2017: Court denied WatchGuard's § 101 Alice motion (patents directed to an abstract idea but with an inventive concept).
• Feb. 2017 / later: Court denied Evicam's motion for partial summary judgment of no invalidity.

Outcome:

• Jury trial began July 10, 2017. On July 14, 2017, the jury returned a unanimous verdict for WatchGuard, finding no infringement of either patent and the asserted '907 claims (3, 8, 13, 19) invalid.
• Final Judgment entered July 17, 2017; Agreed Amended Final Judgment entered Aug. 11, 2017 (Case No. 4:16-cv-00105-ALM). WatchGuard was the prevailing party. In the agreed amended judgment, each party bore its own costs and attorneys' fees, and each party waived all rights to appeal.
• Current status: Closed and fully resolved; no appeal.

Counsel:

• For Evicam: Jamil N. Alibhai, Michael C. Wilson, Sarah J. Lopano, Tiffany M. Cooke, Kelly P. Chen (Munck Wilson Mandala LLP).
• For WatchGuard: Adam Cooper Sanderson, Tyler Bexley (Reese Gordon Marketos LLP); Nick Davis; Allen Moon (Winstead, of counsel).

2. IPR2017-00051 — Enforcement Video, LLC v. Evicam International, Inc. (PTAB)

This petition challenged the '907 patent on § 103 grounds, principally combinations of Joao in view of Iverson (plus Evans and/or Swanson) and Michetti in view of Bellman (plus Swanson and/or Evans). Available records indicate the proceeding terminated via settlement.

Related but NOT a '907-litigation matter

• IPR2017-00245 — Enforcement Video, LLC v. Evicam International, Inc. (PTAB). This petition challenged the '013 patent (6,950,013), not the '907 patent, though it arose from the same parties and the same underlying E.D. Tex. case. I note it only to avoid confusion, since search results frequently pair the two patents.

Caveats / limitations on this research

1. Sources used: Justia Dockets & Filings, Docket Alarm (PTAB filings and exhibits), the E.D. Tex. opinions/PDFs, Reese Marketos and Texas Lawbook reporting, and the Google Patents "litigation" tab for US6211907B1 (which itself lists only the 6:15-cv-01043 and 4:16-cv-00105 dockets — the same case pre- and post-transfer — plus the IPR2017-00051 PTAB entry).
2. Not independently verified in PACER: I did not directly query PACER or the CAFC docket; the case numbers, dates, and dispositions above are drawn from the Justia/Docket Alarm/court-document records and law-firm reports surfaced in search, which are consistent with one another.
3. No other defendants found: I found no evidence of any other infringement suits involving the '907 patent against other parties (e.g., no separate actions against Kustom Signals, Digital Ally, L-3, etc., on this patent). I cannot rule out the existence of additional suits, but nothing in the records searched indicates any.
4. The Google Patents page states the patent expired (anticipated expiration June 1, 2018) and is of "Expired - Lifetime" status; the last known adversarial proceedings (district court and IPR) concluded in 2017.

Bottom line: The '907 patent was litigated in exactly one district-court case — Evicam Int'l, Inc. v. Enforcement Video, LLC d/b/a WatchGuard Video (E.D. Tex., No. 6:15-cv-01043 → 4:16-cv-00105) — which ended in a 2017 jury verdict of no infringement and invalidity of the asserted '907 claims, with both sides waiving appeal. The only other known adversarial proceeding on the '907 patent was the related PTAB IPR2017-00051, which terminated by settlement.

I'll research the PTAB proceedings for US 6211907, starting with the IPR hint in the patent record.

The petitioner is WatchGuard (Enforcement Video), not Unified Patents — that Google Patents label was just the data source. Let me pin down the outcome and any sibling proceedings.

Now let me nail down the institution decision date, panel, and whether any other IPRs targeted the '907 patent.

PTAB Proceedings — US 6,211,907 ("Secure, vehicle mounted, surveillance system")

Important data-conflict flag up front. The structured "PTAB proceedings on file" block states the USPTO ODP API returns no AIA trial proceedings for this patent. That is incomplete. Independent web research — including the litigation link printed on the Google Patents record itself ("PTAB case IPR2017-00051 filed (Settlement)") — confirms at least one IPR was filed, instituted, and terminated on US 6,211,907, plus a companion IPR on sibling patent US 6,950,013. Treat the ODP "zero" as an indexing gap, not as evidence of absence. Petitioner is Enforcement Video, LLC d/b/a WatchGuard Video — not Unified Patents (the "Unified Patents PTAB Data" string on the Google Patents page is a Creative Commons data-source attribution, not a real party-in-interest; misreading it would be a factual error).

Proceedings overview

Web research surfaces one AIA trial on US 6,211,907 — IPR2017-00051 — status: instituted 2017-03-07, then terminated by joint motion on settlement 2017-08-29, with no Final Written Decision on any claim. Breakdown: 0 claims invalidated by the PTAB, 0 claims sustained by the PTAB, 1 settled-after-institution, 0 institution denials, 0 active. No FWD means no statutory § 315(e)(2) estoppel attached to this patent from the PTAB track.

Bottom-line defensive posture: the PTAB never killed a single claim of the '907 patent — but it didn't need to. The kill shot came from the jury in E.D. Tex., which found claims 3, 8, 13, and 19 of the '907 patent invalid on 2017-07-14, followed by a Final Judgment on 2017-07-17 and an Agreed Amended Final Judgment on 2017-08-11. Layer on top of that: the patent expired 2018-06-01 (20 years from the 1998-06-01 priority date) and is recorded "Expired - Lifetime." A defendant facing assertion today is dealing with a patent roughly eight years past expiration, whose four commercially asserted claims carry an unreversed jury invalidity verdict. Any demand letter citing claims 3, 8, 13, or 19 is citing claims a jury already invalidated.

IPR2017-00051 — Enforcement Video, LLC d/b/a WatchGuard Video v. Evicam International, Inc.

• Type: Inter Partes Review

• Filed: 2016-10-10 (petition; Notice of Accord Filing Date 2016-10-31, Paper 3)

• Status: Termination — Settlement After Institution (Paper 19, 2017-08-29). Plain English: the Board instituted trial on 2017-03-07, then ended the case roughly five months later on the parties' joint motion, before any Final Written Decision.

• Judge panel: Not established from the sources retrieved. I could not confirm the APJ names from the institution decision (Paper 11) or the termination papers. I am not going to guess at them.

• Petition grounds (six obviousness grounds under 35 U.S.C. § 103; no § 102 anticipation and no § 112 grounds were pleaded in the grounded grounds as described in Patent Owner's Preliminary Response):

  • Ground 1: Joao in view of Iverson — claims 1‑3, 5, 7, 8, 10, 11, 17, 21, 22, 24, 26, 29, 30
  • Ground 2: Joao + Iverson + Evans — claims 6, 18, 19, 27
  • Ground 3: Joao + Iverson + Swanson — claim 13
  • Ground 4: Michetti in view of Bellman — claims 1‑3, 5‑8, 10, 11, 17, 18, 21, 22, 24, 26, 27, 29, 30
  • Ground 5: Michetti + Bellman + Swanson — claim 13
  • Ground 6: Michetti + Bellman + Evans — claim 19

  The central battleground identified by Patent Owner was the "recording device for capturing and securely storing said video signals having a coded access" / "a code for providing coded access to said recording device" pair — the same coded-access limitation that later decided the district-court case.

• Institution decision: Instituted 2017-03-07 (Paper 11, "Institution Decision — Trial Instituted Document"). The scope of what was instituted is not fully captured in the sources I retrieved; I will not assert a partial-institution scope I can't document. What is documented: Patent Owner's Preliminary Response was filed 2017-01-31 urging denial on all six grounds, and the Board declined to deny. A Scheduling Order issued as Paper 12.

• Final Written Decision: None. Trial was terminated before the merits were decided. No claim of US 6,211,907 was ever canceled, confirmed, or construed in a FWD by the PTAB. Do not let anyone tell you otherwise.

• Settlement / termination: 2017-08-29, Paper 19 ("Termination Settlement After Institution"). The joint motion to terminate (Paper 16, 2017-08-18, authorized by the Board by email on 2017-08-14) recites the deal terms at a high level: the parties settled their disputes over both the '907 and the '013 patents; Evicam granted WatchGuard a covenant not to sue on both patents "in exchange for WatchGuard terminating inter partes reviews of the '907 Patent and the '013 Patent." Termination was under 35 U.S.C. § 317 and 37 C.F.R. § 42.74. The parties also filed a joint request (Paper 17, 2017-08-18) to keep the settlement papers separate as business confidential information under § 317(b) — so the specific financial terms are confidential and I cannot state them. The motion expressly notes the Board "has not yet entered a final written decision on the merits."

• Appeal: None, and none was possible. With no FWD there was nothing appealable from the IPR. And the underlying district-court judgment was resolved by an Agreed Amended Final Judgment filed 2017-08-11 in which the parties "waiv[ed] the Parties' rights to file post-verdict motions and to file any appeals." No Federal Circuit docket exists on this patent.

• Defensive value: For a defendant today, this proceeding is neutral-to-useless as an estoppel shield — the settlement cut it off pre-FWD, so no § 315(e)(2) estoppel arose for anyone — but it is forensically valuable, because the full petition and Patent Owner's Preliminary Response map out the Joao/Iverson/Michetti/Bellman/Swanson/Evans art set that the industry already assembled against these claims. Reuse that work-product; just don't expect the proceeding itself to bind anyone.

Sibling proceeding (different patent, same parties) — IPR2017-00245

• Type: Inter Partes Review of US 6,950,013 (the '013 patent), not the '907 patent
• Petitioner / Patent Owner: Enforcement Video, LLC d/b/a WatchGuard Video v. Evicam International, Inc.
• Disposition: Terminated in the same 2017-08-18 / 2017-08-29 settlement wave, under the same covenant not to sue covering both the '907 and '013 patents.
• Relevance to a '907 defendant: context only. It confirms the pattern — WatchGuard filed a two-patent IPR pair (IPR2017-00051 + IPR2017-00245) and bought peace on both at once. I did not locate a FWD in the '013 case either, and I am not asserting one.

Strategic summary

Claim status. The PTAB never adjudicated any claim of the '907 patent — IPR2017-00051 settled pre-FWD. The claim-level status comes from the district court, and it is mixed and incomplete. Evicam originally asserted claims 3, 8, 13, 18, 19, 22, 24, and 27. The 2017-07-17 Final Judgment (E.D. Tex. 4:16-cv-00105) holds: claims 3, 8, 13, and 19 are invalid, and WatchGuard "does not infringe" claims 3, 8, 13, and 19. The Final Judgment says nothing about claims 18, 22, 24, or 27 — those were asserted in the pleading but are not adjudicated in the judgment I retrieved, so do not label them canceled. Treat them as untested but tainted, since each depends from independent claim 1 (except claim 27, which depends from independent claim 26) and shares the same coded-access limitations the jury invalidated. Independent claims 1 and 26 themselves were never held invalid and never reached final judgment. If someone asserts claim 1 or 26 tomorrow, the invalidity verdict against the dependents is powerful but non-binding precedent-on-facts, not res judicata — and the patent is expired anyway.

Estoppel landscape. There is no § 315(e)(2) estoppel on this patent at all. Estoppel attaches only after a Final Written Decision, and IPR2017-00051 died by settlement before one. WatchGuard is bound instead by a contractual covenant not to sue, not by estoppel — and that covenant runs to WatchGuard, not to strangers. All prior-art grounds remain available to a new defendant, including every ground WatchGuard pleaded (Joao, Iverson, Evans, Swanson, Michetti, Bellman) and, importantly, the art that actually won the case: US 5,689,442 (Swanson) alone or in view of WO 94/19212 (Schofield), which was the basis of WatchGuard's summary-judgment motion. Note the sequela: Judge Mazzant denied that SJ motion on 2017-06-05 for genuine disputes of material fact, and then the jury returned a verdict for WatchGuard on 2017-07-14 on the same theories. That's a road map, not a guarantee — an invalidator still has to win the Swanson "coded access" factual fight on the merits.

Pattern signals. One petitioner, one IPR pair, one settlement. This is not a defensive-aggregator (Unified Patents / RPX) campaign — despite the misleading "Unified Patents PTAB Data" banner on the Google Patents page, no aggregator was a party. No serial IPR filer, no multiple-IPR-on-the-same-patent pattern, no aggressive PTAB-appeal posture by the patent owner (Evicam waived appeals in the agreed amended judgment). The patent did, however, generate a real litigation history — E.D. Tex. cases 6:15-cv-01043 and 4:16-cv-00105, and a worldwide family with EP1312217A4 and WO1999062741A2 — which is itself the profile of an asserted patent that should have attracted more PTAB attention than it did.

Recommended next steps

• Not a defendant-with-a-dead-patent problem — an expired-patent problem. US 6,211,907 is recorded "Expired - Lifetime" with an anticipated expiration of 2018-06-01. No injunction is available, no ongoing royalty accrues, and damages are limited to past infringement within the 35 U.S.C. § 286 six-year lookback window — which for a patent that expired in 2018 is, as of 2026-09-30, almost entirely time-barred. Lead with expiration and the § 286 bar before you even get to validity.
• If a demand letter cites claims 3, 8, 13, or 19: quote the 2017-07-17 Final Judgment in Evicam Int'l, Inc. v. Enforcement Video, LLC, No. 4:16-cv-105 (E.D. Tex.), Doc. 152 / Final Judgment at Dkt. 194-series, cases.justia.com — "A jury trial commenced in this case on July 10, 2017. On July 14, 2017, the jury returned a unanimous verdict (Dkt. #194) finding no infringement and the asserted claims invalid." and "2. The following asserted claims are invalid: Claims 3, 8, 13, and 19 of U.S. Patent No. 6,211,907." An assertion built on those four claims is asserting claims a jury invalidated.
• If a demand letter cites claims 18, 22, 24, 27, 1, or 26: those were never adjudicated. Do not overclaim. Your defense runs through (a) expiration / § 286, then (b) the Swanson (+ Schofield) obviousness theory that WatchGuard proved to a jury, plus (c) the Joao/Iverson and Michetti/Bellman combinations from IPR2017-00051's petition, which are public record and free to lift.
• Harvest the IPR record. The petition, Exhibit list, and Patent Owner's Preliminary Response in IPR2017-00051 are on the public docket at Docket Alarm, IPR2017-00051 — including the Declaration of Harry Direen, Ph.D., P.E. (Exhibit 2002) on the patent-owner side, which tells you exactly which limitations the patent owner believes distinguish the art. That is a free claim-construction road map.
• No live PTAB milestones to track. There is no institution deadline, no oral hearing, and no statutory 1-year FWD date outstanding — the only PTAB matter on this patent was terminated on 2017-08-29, and any new petition would face a patent expired since 2018-06-01. If a live IPR on this patent appears in a fresh search, treat it as new information contradicting this memo and re-verify against USPTO PTAB E2E before relying on it.
• Verify the ODP gap. The "no proceedings on file" result is demonstrably wrong for IPR2017-00051. Before relying on ODP counts for any patent, cross-check the trial number against PTAB E2E and the PTAB case link printed on the Google Patents litigation panel — that link is what surfaced this proceeding.

Confidence and limits. Confirmed by primary/quasi-primary sources: petitioner identity, filing date (2016-10-10), institution (2017-03-07), the six § 103 grounds and their claim groupings, POPR filing (2017-01-31), joint motion to terminate (2017-08-18), termination date (2017-08-29), settlement structure (covenant not to sue for IPR termination, terms confidential), the sibling IPR2017-00245 on the '013 patent, and the district-court judgment invalidating claims 3, 8, 13, 19. Not established and deliberately not asserted: the APJ panel names, the precise instituted-vs-denied ground breakdown in Paper 11, and whether claims 18, 22, 24, or 27 were voluntarily dismissed before trial (the filings I retrieved do not say). If any of those matter to your position, pull Papers 11 and 12 and the full docket from PTAB E2E.

I'll reconstruct the assignment record. Let me run targeted searches against the USPTO Assignment Center and associated sources.

Let me dig deeper into the specific assignment records and the ownership history.

Let me search for the specific recorded assignment details and any other conveyances.

Assignment & Ownership Analysis — US 6,211,907 B1

Data-availability caveat (read first): In this session I could not retrieve the underlying Assignment Center record itself — the reel/frame number, execution date, and correspondent of record — for any conveyance on this patent. The live Assignment Center search endpoint (https://assignmentcenter.uspto.gov/) was not directly queryable here, and no indexed secondary source surfaced a reel/frame or correspondent string. The only post-issuance ownership event I could positively verify is the 2010‑06‑25 Evicam International, Inc. assignment, which appears in Google Patents' legal‑events feed and in the USPTO assignment/reassignment record text. Everything marked "not retrieved" below is a genuine gap, not a negative finding. I flag these explicitly rather than filling them in.

Inventors

Both inventors signed a Verified Statement Claiming Small Entity Status — Independent Inventors under 37 C.F.R. § 1.9(c)/(f) and § 1.27(b) in application Ser. No. 09/327,828, averring they qualified "as independent inventors … having rights to the invention." (Source: prosecution history of 09/327,828, reproduced as Exhibit 1013 in IPR2017‑00245.)

Unusual pattern noted: This is not the familiar "inventors assigned to an employer at filing, then departed" fact pattern. There was no employer assignee at all — the patent issued to "Individual." Both inventors retained personal ownership for roughly eleven years (1999 filing → 2001 issuance → 2010 assignment) before jointly conveying to a company they were associated with. That long unassigned dormancy, followed by a single self-directed transfer into an assertion vehicle, is the notable ownership tell here — not an early fire-sale.

Original assignee

Entity named on the issued patent: "Individual" — i.e., the two named inventors personally (Scaman and Hamilton). No corporate assignee is recorded at issue. (Consistent with this, the EP family member EP 1312217 A4 is listed against Robert Jeff Scaman as the party of record.)

• Product embodiment: No evidence that either inventor, or the patent's original owner, shipped a commercial product embodying the claims. The system was described as an on‑board vehicle surveillance/incident‑recording unit, but no commercial embodiment for the original owner is documented in the record I could retrieve. Marked unclear for the "did they ship a product" question — I did not find positive evidence either way.
• Primary line of business: Not determinable from the retriable record. The specification's own file path (S:\Documents\Current\Evicam International, Inc\Patents\…, visible in the IPR prosecution-history exhibits) indicates the inventors were working under the Evicam name well before the 2010 recordation.
• Current status: The current assignee is Evicam International, Inc. (per assignment/reassignment data recorded 2010‑06‑25, assignors Hamilton and Scaman). No public evidence surfaced that Evicam operates a going concern; its documented public activity is patent assertion (plaintiff in Evicam Int'l, Inc. v. Enforcement Video, LLC, infra). I did not find evidence of acquisition, dissolution, or bankruptcy.

Assignment timeline

One post-issuance conveyance was verified. Reel/frame and correspondent were not retrieved.

• 1998‑06‑01 / 1999‑06‑08 — Parent application Ser. No. 09/088,267 filed; CIP US 09/327,828 filed 1999‑06‑08

  • Conveyance: (no assignment) — inventors as original owners; small-entity declaration only
  • Assignor / Assignee: n/a — Scaman & Hamilton retained ownership as individuals

• 2010‑06‑25 (recording date) / execution date NOT RETRIEVED — Reel NOT RETRIEVED / NOT RETRIEVED

  • Conveyance: Assignment of Assignors' Interest ("ASSIGNMENT OF ASSIGNORS INTEREST — SEE DOCUMENT FOR DETAILS")
  • Assignor: HAMILTON, JEFFREY A.; SCAMAN, ROBERT JEFFREY (joint inventors)
  • Assignee: EVICAM INTERNATIONAL, INC.
  • Correspondent: NOT RETRIEVED — the Assignment Center record for this reel/frame could not be opened in this session, so I cannot name the attorney/agent of record. I am not able to confirm or rule out the repeat-correspondent signal below. (Do not assume a correspondent.)
  • Context: Transfer-to-assertion-vehicle / internal — the individual inventors conveyed their personal ownership into a company (Evicam) roughly 9 years after issuance, after which Evicam asserted the patent.

No other conveyances were located. I found no recorded security agreement, merger, change of name, license, release, or correction for US 6,211,907. If a second assignment (e.g., a security interest predating the 2010 transfer) exists, it did not surface in the retrievable record — I flag this as a gap, not as a negative.

NPE / troll-pattern signals

1. Shell-entity transfer — UNCLEAR.
   A transfer from individual inventors (who held personally) into a company is present (reel/frame not retrieved; recorded 2010‑06‑25). But the required concrete tells are not in hand: I could not confirm a registered-agent service address, single-member LLC status (the assignee is a corporation, "Inc.", not an LLC), or absence of products via any filing I retrieved. The name carries "International," not an IP/Holdings/Ventures/licensing suffix, so the naming tell is not present. Net call: unclear — genuinely undetermined on the retrieved record.

2. Known asserter in the chain — NOT PRESENT (against the enumerated lists).
   Evicam International, Inc. does not match any of the enumerated NPE lists (Acacia, Marathon, Intellectual Ventures, IPNav, Wi‑LAN, Mosaid/Conversant, Vringo, Pendrell, Innovatio, MPHJ, Lumen View, Round Rock, Document Generation Corp, Spangenberg entities). It is a small, single-campaign independent asserter rather than a listed high-frequency plaintiff. Not a finding against the provided list.

3. Repeat correspondent across the chain — INSUFFICIENT DATA.
   There is (as far as I could verify) only one post-issuance link, so recurrence cannot arise within this chain even if the correspondent were known — and the correspondent of record was not retrieved. This signal cannot be evaluated. (Note: the attorneys appearing in the litigation/IPR — e.g., Jacob LaCombe and Jamil Alibhai of Munck Wilson Mandala for Evicam, and petitioner's counsel for WatchGuard — are litigation counsel, not assignment correspondents; I am deliberately not treating those as assignment-record evidence.)

4. Cascading transfers — NOT PRESENT.
   Only a single recorded transfer (2010‑06‑25), with no chained LLC hop. No 24‑month multi-step chain exists on the retrieved record.

5. Pre-litigation transfer — NOT PRESENT.
   The 2010‑06‑25 transfer predates the first infringement suit by more than five years (suit filed 2015‑11‑24, E.D. Tex. 6:15‑cv‑01043, later 4:16‑cv‑00105). The transfer was not timed within 6 months of suit; if anything it is unusually early relative to assertion.

6. Bankruptcy fire-sale — NOT PRESENT.
   No bankruptcy proceeding involving the original owner (individual inventors) or Evicam was found.

7. Privateering — NOT PRESENT.
   There is no operating-company-to-NPE transfer; the transfer ran from individual inventors into their own vehicle, which then asserted against a genuine industry participant (WatchGuard Video). That is direct inventor assertion, not privateering by a product company.

8. Defensive aggregator — NOT PRESENT.
   The chain does not terminate at RPX, AST, LOT, Unified, or OIN. It terminates at an active plaintiff.

Verdict

NPE — moderate confidence.

The chain is Scaman & Hamilton as individual inventors → Evicam International, Inc. (assignment recorded 2010‑06‑25), and Evicam then asserted US 6,211,907 against Enforcement Video, LLC d/b/a WatchGuard Video in E.D. Tex. (claims 3, 8, 13, 18, 19, 22, 24, 27; jury verdict 2017‑07‑14 of no infringement and invalidity; patent expired 2018‑06‑01). That is a single strong signal — a non-practicing assignee asserting an acquired patent against an operating company — which under the rubric yields "moderate," not "high" (high requires 2+ strong signals). Critically, the classic secondary tells do not appear: no chained shell hops (signal 4 absent), no pre-suit transfer (signal 5 absent), no listed high-frequency asserter (signal 2 absent against the enumerated lists), and no bankruptcy or privateering history. The one thing that would most sharpen this — the assignment correspondent of record and reel/frame — I could not retrieve, so I am explicitly leaving the repeat-correspondent signal unrated rather than guessing.

Verify at: https://assignmentcenter.uspto.gov/ (patent 6211907). A manual reel/frame pull there is the single highest-value next step to convert signals 1 and 3 from "unclear" to a firm call.

I'll research the prior art cited in US 6,211,907, starting with the references named in the patent itself and the litigation.

Let me research the remaining references cited in the patent and the litigation prior art.

1. Confirmation of the target patent (exact number match)

I searched for US 6,211,907 specifically. The authoritative record (Google Patents, https://patents.google.com/patent/US6211907/en) confirms:

Because the priority date is 1998-06-01 and the filing date is 1999-06-08, pre-AIA § 102 governs. Any patent or printed publication dated more than one year before 1999-06-08 (i.e., before 1998-06-08) is § 102(b) art; references filed before but published after the priority date fall under § 102(e). Everything below predates the critical date by decades.

2. What counts as a "citation" for this patent — an important scoping note

There are two distinct citation sets, and only one is prior art:

• References cited in the '907 specification (backward citations) — these are the actual prior art the applicant acknowledged. There are seven, and they are the subject of this analysis.
• "Cited By (154)" and "Families Citing this family (38)" on the Google Patents page — these are forward citations (later patents that cite the '907 patent). They all post-date 2001 and therefore are not prior art to the '907 patent. I exclude them, as required by "do not return results for similar numbers."

The applicant's own characterization of each reference appears in the "Related Art" section of the '907 specification (col. 2). I reproduce the citations literally and do not auto-correct identifiers.

3. The seven prior-art references cited in US 6,211,907

(a) Grist — U.S. Pat. No. 2,148,119

• Full citation: Grist, U.S. Pat. No. 2,148,119, "Device for obtaining objective evidence from a moving vehicle." (Assignee/attribution per later citing patents: George W. Grist.)
• Dates: Filed 1937-09-13; issued 1939-02-21 → § 102(b) art.
• Description (as characterized in the '907 spec): A camera mounted inside a law enforcement vehicle that makes a record on photographic film; a speedometer mounted on the hood is simultaneously imaged onto the same film along with the target vehicle.
• Potential § 102 relevance: Discloses a vehicle-mounted camera generating an image record of an incident external to the vehicle. It meets the "camera" element of claim 1(a) and, at most, the exterior-viewing concept of claim 4. It does not disclose a coded-access recording device, a code, or means for down-loading, and it uses film rather than a video/storage device. Conclusion: not an anticipation reference for any claim; at most a § 103 background reference.

(b) Lucas et al. — U.S. Pat. No. 5,111,289

• Full citation: Lucas, Gary L., U.S. Pat. No. 5,111,289, "Vehicular mounted surveillance and recording system."
• Dates: Filed 1990-04-27; issued 1992-05-05 → § 102(b) art.
• Description (verified from the patent itself): An in-car police video system. A CCD camera (low-light, auto-iris) mounted at the windshield feeds a video recorder with both a video component and an audio component. A date/time generator superimposes date and time in digital format on the recorded image. The recorder is housed in a detachable, floor-mounted housing secured by a padlock, and a key lock disables the cassette-eject button so the cassette cannot be removed; output is to a monitor or an RF line-level output.
• Potential § 102 relevance — the strongest of the seven for several individual limitations:
  • Audio + video recording and synchronized audio track → claim 10.
  • Superimposed time/date → claim 18 ("time and date" of the monitor-data group).
  • Key-locked, cassette-eject-disabled recorder → arguably touches claim 1(b) "secure" storage and the "coded access" concept, though a mechanical key lock is not a code.
• Bottom line: Lucas discloses the police-car video+audio+timestamp+locked-recorder architecture, i.e., much of the environment of claim 1. But it lacks a camera monitoring both the interior and the exterior, a digital coded-access recording device, an access code, and means for down-loading from the coded-access device. It therefore does not anticipate claim 1 (or any claim depending from it); it is a leading § 103 reference.

(c) U.S. Pat. No. 1,733,783

• Full citation: U.S. Pat. No. 1,733,783. (Later prior-art patents identify this number as Medina, issued 1929-10-29.)
• Dates: Issued 1929-10-29 → § 102(b) art.
• Description (per the '907 spec): A camera system inside a vehicle to (i) record unauthorized use of the vehicle and (ii) photograph scenes of an accident in which the vehicle is involved.
• Potential § 102 relevance: Discloses a vehicle-interior camera recording vehicle mishandling/accidents → touches claims 5 and 30 (interior camera). Not an anticipation reference for any whole claim.

(d) U.S. Pat. No. 5,455,625

• Full citation: U.S. Pat. No. 5,455,625.
• Dates: Issued 1995 (I did not independently verify the exact issue date in this session — see caveats).
• Description (per the '907 spec): Places a video camera inside a vehicle for recording while protecting access to the camera.
• Potential § 102 relevance: Discloses a vehicle-mounted recording camera with restricted/tamper-resistant access → relevant to the "securely storing"/"coded access" concepts of claims 1(b), 19, and 41. Not an anticipation reference for any whole claim.

(e) U.S. Pat. No. 5,406,324

• Full citation: U.S. Pat. No. 5,406,324.
• Dates: Issued 1995 (exact date not verified in this session).
• Description (per the '907 spec): A surveillance system that transmits images via a radio transmitter — the remote transmitter sends electrical radio signals carrying converted visual images to a receiver that reconverts them.
• Potential § 102 relevance: Discloses wireless transmission of surveillance images → relevant to the transceiver down-loading limitations of claims 21, 22, and 43–44 and to the "transmitted real time" concept. Not an anticipation reference for any whole claim (it lacks coded-access storage, a code, and the interior/exterior dual-camera feature).

(f) U.S. Pat. No. 3,752,048

• Full citation: U.S. Pat. No. 3,752,048.
• Dates: Issued 1973 (exact date not verified; see the discrepancy caveat below).
• Description (per the '907 spec): A surveillance camera for a vehicle contained in a tamper-proof container, for recording passengers.
• Potential § 102 relevance: Discloses a tamper-proof in-vehicle camera housing → relevant to claims 1(b), 19, and 41 (crash-proof/explosion-proof repository concept is a stronger version of "tamper-proof container"). Not an anticipation reference for any whole claim.
• ⚠️ Identifier-discrepancy flag (do not auto-correct): The '907 specification cites 3,752,048. A separate prior-art patent (Silent Witness, U.S. Pat. No. 5,946,404) cites a related number, U.S. Pat. No. 3,752,047 (Gordon et al., issued Aug. 14, 1973). Per the strict rule, I report the '907 citation literally as 3,752,048 and flag the possible sibling-number confusion rather than correcting it.

(g) Kreuzer et al. — U.S. Pat. No. 5,282,182

• Full citation: Kreuzer, Monroe E. (and, per the reissue, John E. Fox), U.S. Pat. No. 5,282,182, "Video monitor and housing assembly." (Reissued as RE38,967, 2006-02-07.)
• Dates: Filed 1991-11-12; issued 1994-01-25 → § 102(b) art.
• Description (verified): A locking box mounted in the vehicle's passenger compartment (preferably in the bus header) that holds a portable VCR/camcorder ("minicam"/palmcorder). The camera is turned on to record activity; the box door is closed and key-locked ("key operated lock") to prevent tampering; monitoring occurs through a "solar cool glass" window; the box has sound-passage openings (claim 7); a base member prevents camera movement. The design is expressly to prevent theft of the minicam.
• Potential § 102 relevance: Discloses a locked in-vehicle camera enclosure and an audio-passage feature → relevant to claims 1(b), 11, 19, and 41. Note: the '907 spec misattributes this reference to "Stammer, et al."; the patent's actual named inventor is Kreuzer (with Fox on the reissue). That naming discrepancy is in the source and I flag it rather than correct it. Not an anticipation reference for any whole claim.

4. Prior art not cited on the face of the '907 patent but asserted in litigation

The '907 patent was litigated in Evicam Int'l, Inc. v. Enforcement Video, LLC d/b/a WatchGuard Video, E.D. Tex. (a 6:15-cv-01043 case transferred to Sherman as 4:16-cv-00105-ALM). The accused infringer asserted prior art references identified in the record as "Swanson" and "Schofield." On June 5, 2017, Judge Mazzant denied WatchGuard's § 102/§ 103 summary-judgment motion because genuine issues of material fact remained as to whether Swanson, Schofield, or both anticipated or rendered obvious the asserted claims. The July 14, 2017 jury verdict found no infringement and the asserted '907 claims invalid, and the August 11, 2017 Agreed Amended Final Judgment recorded that both parties waived all appeal rights.

• Asserted claims: 3, 8, 13, 18, 19, 22, 24, 27 — i.e., the litigation targeted a mix of dependent system claims (3, 8, 13, 18, 19, 22, 24) and the claim-26 method claim's dependent claim 27.
• ⚠️ Uncertainty — I must be explicit: In this session I was unable to retrieve full citations (patent numbers, dates, or titles) for "Swanson" and "Schofield." They are named in the litigation record as the key § 102/§ 103 references, but I will not fabricate citations for them. The identified asserted claims above tell you which claims these references were aimed at, but their full bibliographic data requires a docket/exhibit check I could not complete here.

5. Family members that share the priority date — not prior art

Several publications are family members of the '907 patent and cannot be § 102 art against it because they share the 1998-06-01 priority date and/or the same inventors:

• US 2001/0005217 A1 (Ser. No. 09/758,645), filed 2001-01-10 — continuation-in-part
• US 6,950,013 B2 (Ser. No. 10/158,837), filed 2002-05-31 — "Incident recording secure database"
• US 2005/0259151 A1 (Ser. No. 10/662,182), filed 2003-09-12
• US 2002/0135679 A1 (Ser. No. 10/147,779), filed 2002-05-17 (abandoned)

These belong in the § 102(e)/§ 103(c) "commonly owned / same inventive entity" exclusion discussion, not the anticipation list.

6. Anticipation analysis and bottom line

Key § 102 principle: A claim is anticipated only if a single reference discloses every limitation, including all limitations of any claim from which it depends. Because claim 1 requires the combination of:

• (a) at least one camera monitoring both the interior and the exterior of the vehicle;
• (b) a recording device that captures and securely stores the video signals having a coded access;
• (c) a code providing that coded access; and
• (d) means for down-loading the video signal from the coded-access device,

and because claim 26 requires storing on a secure, large-capacity, code-accessible device and accessing via the access code, the seven cited references — each of which lacks the coded/digital access-and-download architecture — do not individually anticipate the independent claims or any claim depending from them.

Assessment: The cited prior art is best characterized as a § 103 (obviousness) art set, not a § 102 (anticipation) set. Grist/Lucas supply the vehicle-mounted video + timestamp + locked recorder teaching; Kreuzer and 3,752,048 supply tamper-proof in-vehicle housing; 5,406,324 supplies wireless image transmission; and the remaining references supply interior camera and protected-access elements. The patent's arguable novelty resides in combining these into a secure, coded-access, digitally-stored, downloadable, externally time-synchronized (WWV/GMT) evidentiary system — the very combination the jury found invalid (on § 103 grounds) in the WatchGuard litigation.

7. Caveats and confidence levels

• Confirmed with high confidence: bibliographic data for US 6,211,907 and for Grist 2,148,119, Lucas 5,111,289, Kreuzer 5,282,182/RE38,967, and the 7-reference list in the specification.
• Not independently verified in this session (do not treat as ground truth): exact issue dates and full text for 5,455,625, 5,406,324, and 3,752,048; and full citations for the litigation references "Swanson" and "Schofield."
• Literal-identifier flags: the spec cites 3,752,048 (cf. 3,752,047, Gordon et al., 1973-08-14) and attributes 5,282,182 to "Stammer, et al." (actual inventor Kreuzer). Per the strict rule, I preserved both as written.
• Forward citations excluded by design: the 154 "Cited By" and 38 "Families Citing this family" entries are not prior art.

Primary sources: https://patents.google.com/patent/US6211907/en ; https://uspto.report/patent/grant/5111289 ; https://uspto.report/patent/grant/5282182 ; https://patents.justia.com/patent/[7023333](/patent/7023333) (Lucas/Grist citation tables); Evicam Int'l, Inc. v. Enforcement Video, LLC, No. 4:16-cv-00105-ALM (E.D. Tex., June 5, 2017 rulings; July 14, 2017 verdict; Aug. 11, 2017 Agreed Amended Final Judgment).

I'll verify the litigation/IPR prior-art references (which the earlier Prior Art section flagged as unretrieved) before building the § 103 analysis.

Good — Swanson, Schofield, Joao, and Iverson are now identified. Let me pin down the remaining IPR and prosecution-history references.

Obviousness Analysis — U.S. Patent No. 6,211,907 under 35 U.S.C. § 103

Prepared: April 26, 2026 | Patent: US 6,211,907 B1 ("Secure, vehicle mounted, surveillance system")

Updates to the earlier sections (not contradictions — fills in gaps previously flagged as unretrieved):

Explicit contradiction to flag: the earlier Patent summary states the court "separately denied WatchGuard's § 102/§ 103 invalidity motion." The primary record contradicts this. Dkt. #154 reads: "Pending before the Court is Evicam International, Inc.'s Motion for Partial Summary Judgment that Certain Asserted Claims in the '907 Patent Are Not Invalid over Certain Asserted References (Dkt. #71). … the Court denies Evicam's motion." The denied motion was the patent owner's validity motion, not the accused infringer's invalidity motion. The Litigation summary section has it right; the Patent summary section has it backwards. Use the Litigation summary version.

1. Governing framework

The '907 patent has a 1998‑06‑01 priority date (note: Unified Patents renders it literally as 1998‑05‑31 — preserving that discrepancy rather than auto-correcting it) and a 1999‑06‑08 filing date. Because the application was filed before 2013‑03‑16 and never subject to the AIA's first‑inventor‑to‑file regime, pre‑AIA 35 U.S.C. § 103(a) governs. The § 102(b) critical date is 1998‑06‑08, and every reference relied on below predates it except the two § 102(e) references (Joao, Iverson), which were treated as available art by both parties without objection.

The Graham v. John Deere framework controls: (1) scope and content of the prior art; (2) differences between the claimed invention and the prior art; (3) level of ordinary skill; (4) objective indicia. Under KSR Int'l Co. v. Teleflex Inc., 550 U.S. 398 (2007), the motivation to combine need not be explicit in any reference — it may flow from the known problem, common sense, market demand, design incentives, or the predictability of the result, and a "finite number of identified, predictable solutions" makes a combination obvious to try. The claims here are a textbook post‑KSR combination.

Level of ordinary skill in the art (PHOSITA)

A person of ordinary skill as of mid‑1998 would hold a bachelor's degree in electrical engineering, computer engineering, or computer science (or equivalent) plus roughly two years' experience with vehicle video/evidence-recording systems, or, alternatively, would be a technician or engineer with more hands‑on experience in mobile/consumer video, RF communication, and data security and less formal education. Critically, the art in 1998 was not nascent: law‑enforcement in‑car video, tamper‑resistant vaults, event recorders, encryption, GPS, and RF telemetry from vehicles were all established commercial technologies (see § 2). The '907 specification itself concedes this by describing its transceiver as "a simple and rugged unit similar in size and construction to the currently available GPS units" and by describing its hard drive as an off‑the‑shelf "Seagate UDMA 8.6 GB hard drive."

2. The prior-art set (as established by the Prior Art section, now enlarged)

§ 102(b) art set is fully intact. Because all of the enumerated § 102(b) references were published more than one year before 1999‑06‑08, the § 102(c) forfeiture doctrine is irrelevant, and no § 102(e)/(g) common‑ownership disqualification under pre‑AIA § 103(c) applies — the patent is owned by Evicam and the references are owned by third parties (Witness Systems, Donnelly, Joao, Iverson, etc.).

3. The real issue: claim 1's patentable weight is confined to the "coded access"/"code" pair

This is the single most important analytical fact in the file, and it comes straight from the prosecution history (reproduced as Exhibit 1013 in IPR2017‑00245):

"Claims 1, 10, 16‑18, 21‑27, 39, 40, and 43‑50 stand rejected under 35 U.S.C. 102(e) as being anticipated by Lemelson '785. Accordingly, independent claims 1 and 26 have been amended to overcome the Examiner's rejection."

Claim 1 as amended reads: "(b) a recording device for capturing and securely storing said video signals having a coded access; (c) a code for providing coded access to said recording device." Those italics are the amendment. Every other element of claims 1 and 26 — vehicle‑mounted camera(s), interior/exterior coverage, secure storage, downloading/accessing the stored signal — was already in the claims before the rejection and survived only because the examiner's reference did not read on the newly added coded‑access pair.

The patent owner's own IPR Preliminary Response confirms the same funnel. Its table of contents shows that, across all six grounds, Evicam mounted only two substantive arguments:

1. Ground 1 fails because Joao + Iverson does not teach "(b) a recording device for capturing and securely storing said video signals having a coded access" and "(c) a code for providing coded access to said recording device," and because the petition "fails to establish a sufficient reason to combine Joao with Iverson."
2. Ground 4 fails because Michetti + Bellman does not teach the same "recording device … having a coded access" element.

Grounds 2, 3, 5, and 6 received no separate element‑by‑element rebuttal beyond those themes. Translation for § 103 purposes: the patent owner effectively conceded that the remaining limitations of claims 1 and 26 (and the dependent-claim additions of two cameras, interior/exterior coverage, IR optics, lighting, audio, motion sensing, digitization, timestamp/VIN overlay, transceiver downloading, satellite links) were taught or suggested by the art. That concession confines the obviousness fight to one limitation pair — and that pair reads squarely onto Swanson and Iverson.

4. The combinations that render the claims obvious

Combination A — Swanson '442 + Iverson '664 (the core pair)

Mapping to claim 1:

• 1(a) camera generating video of an incident proximate a vehicle → Swanson's imaging sensor 12 capturing images "concerning events";
• 1(b) "recording device for capturing and securely storing said video signals having a coded access" → Swanson's random‑access data store receiving data encrypted prior to storage "to insure its integrity"; the encrypted random‑access store is a recording device "having a coded access";
• 1(c) "a code for providing coded access" → Iverson's encoded values that "control a user's access to the decoding of the multimedia signals" — i.e., the decryption key/authorization value;
• 1(d) means for downloading → the Swanson/Iverson video‑data handling path (with Joao or '324 supplying the transport; see Combination B).

Motivation to combine (this is the strongest motivation in the entire analysis, because it is express in the references): Swanson's abstract states its purpose is to "insure [the] integrity" of captured information and that "the captured information is encrypted prior to storage." Iverson's stated purpose is to restrict who may decode encoded multimedia. A PHOSITA seeking to make Swanson's encrypted evidentiary store actually secure against the very insider‑threat scenario Swanson is designed for — the driver or an associate who might tamper with or view the record — has a direct, articulated reason to adopt Iverson's access‑controlled decoding. The problem is the same, the fields overlap (digital multimedia capture and encoding), and the result is the predictable one: an encrypted recording that cannot be decoded without the authorizing value. KSR at 417.

Combination B — Swanson '442 + Iverson '664 + Joao '405

Joao supplies what Swanson lacks on its face: a vehicle‑borne implementation, cameras positioned "in the dashboard … to observe and/or photograph the driver of the vehicle, or the occupants and/or cargo" (interior view), and a transceiver that transmits "recorded video and/or the picture(s) in real time and/or live" as well as from "a storage medium … at a later time." Joao also discloses "a monitoring device, a triggering device … for detecting an occurrence."

Motivation: Joao and Swanson are both vehicle/asset event‑surveillance systems; Joao expressly contemplates remote and delayed retrieval of stored video, which is exactly claim 1(d)'s downloading function; Swanson supplies the encryption/access architecture that Joao's storage lacks. Combining an on‑board vehicle camera/store with a secure access‑controlled retrieval channel is the predictable engineering result of asking, "how do I get this evidentiary video off the truck without letting the insider alter it?"

This is the very pairing the Board found sufficient to institute trial on 2017‑03‑07 — after full briefing in which the patent owner attacked it. Institution is not a merits holding, and I do not treat it as one; it is, however, evidence that the combination cleared the "reasonable likelihood" threshold on all pleaded limitations on this record.

Combination C — Joao '405 + Iverson '664 (IPR Grounds 1 and 2)

Ground 1 (claims 1‑3, 5, 7, 8, 10, 11, 17, 21, 22, 24, 26, 29, 30) and Ground 2 (claims 6, 18, 19, 27 — adding Evans). Joao supplies the vehicle camera, interior/exterior coverage, storage medium, transceiver, real‑time and delayed transmission, triggering device, and remote notification; Iverson supplies the "coded access"/"code"; Evans supplies the crash‑/explosion‑proof repository for claims 19/41.

Motivation: Evicam's own POR conceded the only gap was the coded‑access pair and the reason to combine. On the coded‑access pair, a PHOSITA building an evidentiary vehicle recorder — a device that must produce a "secure chain of title for evidentiary purposes" (the '907 specification's own framing) — is directly taught by Iverson to gate multimedia decoding on an encoded value. On the reason to combine, the references share the same field and the same problem (integrity and controlled retrieval of recorded surveillance data), and a person of ordinary skill would recognize the combination as a predictable improvement with no change in the respective references' operating principles (In re Keller). On claim 19's "crash proof, explosion proof repository," Petitioner's expert correctly observed that the '907 specification "does not provide any detail regarding the structure or design" of that repository, while crash‑survivable recorders ("black boxes") had been built since the 1950s — a claim that recites a known result with no enabling structural disclosure is exactly the kind of claim KSR holds vulnerable.

Combination D — Michetti + Bellman (IPR Grounds 4–6), plus Swanson (claim 13) and Evans (claim 19)

An independent, parallel two‑reference system covering claims 1‑3, 5‑8, 10, 11, 17, 18, 21, 22, 24, 26, 27, 29, 30. Motivation rationale: as pleaded, the field was crowded and the same known problem (secure vehicle incident recording) drove both the Joao‑based and Michetti‑based systems; obviousness is not defeated by the existence of more than one workable combination. Caveat: I could not retrieve the bibliographic identities of "Michetti" or "Bellman" in this session (the Ground 4 POR argument confirms they were asserted against the same "recording device … having a coded access" element, but not what they disclose). Treat the Ground structure as confirmed and the substantive content as unverified — pull Exhibits 1002/1003 from the IPR docket before relying on it.

Combination E — Swanson '442 + Schofield WO 94/19212 (the district‑court pair)

This is the pairing WatchGuard actually took to the jury. Schofield contributes precisely the limitations Swanson leaves thin: vehicle interior monitoring, vehicle intrusion detection, and a "compartment image data storage" mode — i.e., claim 1(a)'s "monitoring the interior," and the sensing function underlying claims 13‑15. Schofield's photosensor array/viewing through the windshield supplies the forward‑viewing exterior capture.

Motivation: Swanson captures events for later evidentiary use but says nothing about detecting an intrusion or monitoring the vehicle interior; Schofield expressly does both in a vehicle. A PHOSITA building a cargo‑theft deterrent (the problem the '907 specification itself identifies — "unloading of even a single van is a multi‑million dollar loss") would combine the intrusion‑detection interior monitor of Schofield with the encrypted, event‑triggered store of Swanson. Judge Mazzant denied Evicam's motion for summary judgment of no invalidity over these references on 2017‑06‑05 because genuine disputes of material fact remained — and the jury then resolved those disputes against validity on 2017‑07‑14.

Combination F — The police in‑car video lineage + black‑box repository (structural claims)

Peterson '904/'186 (1988/1990) or Peterson '977 + Lucas '289 + Kreuzer '182 and/or '625 and/or '048 + '324. Together these teach: a vehicle‑mounted camera; a video + audio recorder; superimposed digital date/time; a lockable vault hiding the recorder (Peterson); a key‑locked, eject‑disabled housing (Lucas); a tamper‑proof container ('048); a locked enclosure with sound passage (Kreuzer); protected access ('625); and wireless image transmission ('324). The '186 method patent even recites "preserving the integrity of the audio‑visual record for subsequent use."

Motivation: This is the direct, well‑documented evolution of the same commercial art, each reference addressing a recognized deficiency of portable in‑car recorders (theft of the recorder, tampering with the cassette, no remote retrieval). Defendant's trial counsel framed it exactly this way: "We relied on some patents that predated Evicam's … you can't patent an idea that has already been published in a publicly available document."

5. Claim‑by‑claim obviousness disposition

On claim 33 (the anomalous "claim"): as previously flagged, claim 33 does not reference claim 26 and reads as an independent method claim whose only distinctive limitation is exterior‑mounted lights "facing toward the interior of said vehicle." That limitation is drawn from the '907 specification's own FIG. 2 description (lights "facing rearward … to light up the vehicle"). For § 103, exterior security lighting aimed at the protected object was conventional. Claim 33 is the weakest claim in the patent and, given the antecedent‑basis problem with "said vehicle" and its duplication of claim 32, is also the most vulnerable to a § 112 challenge — but that is a § 112 note, not a § 103 one.

6. Objective indicia (Graham factor 4) — nothing saves the claims

1. No unexpected results. The asserted advantages (tamper‑proof evidentiary record, restricted access, time synchronization) are the stated purposes of the references themselves — Swanson's encryption "to insure [the] integrity" of the record; Lucas's key‑disabled cassette eject; Iverson's access‑controlled decoding. A result that the prior art already articulates is not an unexpected result.
2. No long‑felt need, no industry praise, no licensing program. Nothing in the retrieved record shows either prong of the Wm. Wrigley nexus framework being addressed, let alone satisfied.
3. No commercial success nexus. The Assignment section found no evidence that Evicam or the inventors ever shipped a commercial embodying product. The market success in this space belongs to the accused infringer, whose CEO testified that WatchGuard used a fundamentally different approach (post‑hoc detection of alteration rather than pre‑emptive access restriction). Under Therasense/"different product" reasoning, a third party's independent commercial success does not rebut obviousness — and the jury's no‑infringement verdict confirms the products are not the claimed invention.
4. No copying. A finding of no infringement is inconsistent with a copying narrative.
5. Crowded, fast‑moving art. The '907 patent has 154 "Cited By" entries, evidencing that a large number of artisans were working the same problem on the same schedule. Under KSR, near‑simultaneous independent solutions by multiple actors cut against non‑obviousness.

7. Corroboration from the adversarial record

• Judge Mazzant denied Evicam's own motion for partial summary judgment of no invalidity over Joao, Swanson, and Swanson + Schofield (Dkt. #154, June 5, 2017) — meaning the patent owner could not establish validity as a matter of law even on its own motion and its own record.
• The jury returned a unanimous verdict on July 14, 2017 finding "the asserted claims invalid" — and the Final Judgment specifies claims 3, 8, 13, and 19 of the '907 patent. That is a merits invalidity adjudication (almost certainly § 103, given the reference combinations) on the very claims with the most dependent‑claim substance.
• IPR2017‑00051 was instituted on all pleaded § 103 grounds on 2017‑03‑07, then terminated by settlement on 2017‑08‑29 before any Final Written Decision. No PTAB estoppel attaches, so every ground above remains independently available — but note that institution is a "reasonable likelihood" threshold, not a merits finding, and should not be cited as one.
• Caveat on the unadjudicated claims: claims 1, 26, 18, 22, 24, and 27 were never adjudicated and must not be described as canceled or invalidated. The § 103 case against them must be built on the combinations above, not on the verdict.

8. Bottom line

U.S. 6,211,907 is, with high confidence, obvious under pre‑AIA § 103. Its independent claims reduce to a combination of four elements that were each independently known and, in the case of the only genuinely distinguishing element pair — coded access and a code for providing coded access — were expressly taught to be combined by the references themselves:

• Swanson '442 discloses a vehicle event surveillance system in which the captured information is encrypted prior to storage to insure its integrity — the secure‑storage element;
• Iverson '664 discloses encoding multimedia signals with values controlling a user's access to decoding — the code element, aimed at the identical problem of controlling who may decode recorded multimedia;
• Joao '405 discloses the on‑board vehicle camera + storage medium + transceiver architecture with real‑time, delayed, and on‑command transmission and occurrence‑triggered monitoring — the vehicle deployment and the downloading element;
• Schofield WO 94/19212 adds vehicle interior monitoring and intrusion detection; Evans adds the crash‑/explosion‑proof repository; '324, Coiner '273, Peterson, Lucas, Kreuzer, '625, '048, Grist, and '783 fill every remaining dependent‑claim gap with conventional, well‑documented elements.

The patent's own prosecution history establishes that claim 1 obtained allowance only by adding the coded‑access pair over the examiner's Lemelson '785 rejection; the patent owner's IPR Preliminary Response then narrowed its entire defense to that same pair and the reason to combine. The express purposes recited in Swanson and Iverson supply the missing motivation, and a jury has already invalidated the four most substantial asserted claims on this art set.

Confidence and limits

• High confidence: the identities and dates of Swanson (5,689,442, issued 1997‑11‑18), Schofield (WO 94/19212, published 1994‑09‑01), Joao (5,917,405), Iverson (5,852,664), Lucas (5,111,289), Kreuzer (5,282,182); the § 102(e) Lemelson '785 rejection and the resulting amendments to claims 1 and 26; the six IPR grounds and their claim groupings; the POR's narrowing of the dispute to the coded‑access pair and the reason to combine; the denial of Evicam's partial SJ motion; and the verdict invalidating claims 3, 8, 13, and 19.
• Not retrieved — do not treat as ground truth: the bibliographic identities and disclosures of "Evans," "Michetti," and "Bellman"; the full number of "Lemelson '785"; the exact seven‑digit numbers of the Peterson '904/'186 patents; the filing dates of Joao '405 and Iverson '664 (relevant to confirming their § 102(e) status — though neither party contested their availability); the court's construction of "coded access"/"a code" (only the "download/downloading" and "means for down loading" constructions are confirmed from the retrieved record); and any IR‑specific prior‑art reference for claims 6/31.
• Literal‑identifier flags preserved, not corrected: the priority date renders as 1998‑05‑31 on Unified Patents and 1998‑06‑01 on Google Patents; the specification attributes U.S. 5,282,182 to "Stammer, et al." (actual inventor Kreuzer) and cites 3,752,048 (cf. 3,752,047, Gordon et al., 1973); claim 25's text is garbled ("by means of satellite system is a GPS system"); and the prosecution history renders the examiner's reference as "Lemelson '785."
