Cedar Lane Technologies Inc. v. Vanguard Integrated Solutions

I'll research this case and the patent before drafting.

Good initial grounding. Now let me dig into the defendant, the docket's later history, and any PTAB proceedings.

Case Overview — Cedar Lane Technologies, Inc. v. Vanguard Integrated Solutions, Ltd., No. 6:22-cv-00968 (W.D. Tex., Waco Div.)

The parties. Cedar Lane Technologies Inc. is a Canadian non-practicing entity headquartered at 560 Baker Street, Suite 1, Nelson, British Columbia — the address recited in its complaints across the campaign. The Stanford NPE Litigation Database categorizes Cedar Lane as an "Acquired patents" asserter, and by the time this suit was filed the company had become one of the most prolific filers in the country, having asserted a small portfolio of legacy image-sensor and JPEG-interface patents against dozens of camera, CCTV, DVR, and consumer-electronics defendants. Its counsel of record here was Isaac Rabicoff of Rabicoff Law LLC (the firm that appears in nearly all of the Cedar Lane W.D. Tex. filings), often alongside Napoli Shkolnik. The defendant, Vanguard Integrated Solutions Ltd., is a comparatively small security-technology integrator — its website (vanguard-is.com) markets IP-based surveillance and "smart city" solutions: IP cameras, DVR/NVR recording systems, ALPR/traffic-monitoring cameras, X-ray baggage scanners, access control, and video analytics. Third-party corporate profiles describe a Dubai-based FZ-LLC (founded c. 2004, roughly 100–200 employees) with earlier UK-linked marketing presence; several unrelated entities share the "Vanguard Integrated Solutions" name (including a Mississauga, Ontario firm), so the precise legal entity served is not something I could confirm from public records. The important structural point is that Vanguard is a foreign integrator/reseller, not a U.S. chip or sensor manufacturer — which shaped both the infringement theory and the service problems that killed the case.

The patent and the accused technology. The case metadata and Stanford's database identify U.S. Patent No. 6,972,790 ("Host interface for imaging arrays") as the patent at issue. Issued December 6, 2005 from an application filed December 21, 2000 (priority January 2000), invented by Mark Suska, and prosecuted by McAndrews Held & Malloy, the '790 claims an interface — preferably integrated on the same die as a CMOS image sensor — that buffers imaging-array data and clocking signals in a FIFO or addressable memory, and uses a "signal generator" that issues an interrupt or bus request to the host processor based on the quantity of data in the buffer. In one line: on-chip glue logic that decouples the sensor's rigid clocking from the processor's asynchronous bus, so the host can service the camera in bursts. Two caveats worth flagging. First, commercial litigation databases (Patsnap; Unified Patents' portal) list three patents in this docket — the '790, its divisional U.S. 8,537,242 (method claims covering the FIFO-counter/compare/interrupt routine), and U.S. 6,473,527 ("Module and method for interfacing analog/digital converting means and JPEG compression means") — because Cedar Lane's standard-form complaint bundled that trio; the case metadata here and Stanford's entry key on the '790 alone. I could not pull the actual complaint PDF to see which counts were pled against Vanguard specifically. Second, the '790 is recorded as inactive/expired, with an estimated expiry of August 1, 2023 — a database-derived status I could not confirm against a maintenance-fee or terminal-disclaimer record, but one that would have sharply limited the damages window. The accused instrumentality is described in the complaint only as "Exemplary Defendant Products" with claim-chart exhibits; given the portfolio and the campaign, the targets were almost certainly Vanguard's camera, DVR/NVR, and video-server products rather than any component Vanguard manufactures, but the specific models are not publicly documented in the sources I could reach.

Posture, venue, and why it matters. The

I'll dig into this. Let me start with several parallel searches.

Good — the case is real. Now let me pull the docket, complaint, and check for PTAB activity.

Cedar Lane Technologies Inc. v. Vanguard Integrated Solutions, Ltd., No. 6:22-cv-00968 (W.D. Tex.)

Bottom line: This is a short, low-complexity case that never got past service of process. It is a single-defendant, single-patent (per the case metadata) infringement action filed 2022-09-16 in Judge Alan D. Albright's court in Waco and terminated 2025-09-22 by Cedar Lane's own Rule 41(a)(1)(A)(i) notice of voluntary dismissal without prejudice — 1,102 days after filing, with no answer, no counterclaims, no motion practice of substance, no Markman, no discovery, no trial, and no appeal. There is no reported opinion, so the entire record is docket-based.

A caveat up front on sourcing: the docket below is reconstructed from Patexia's docket mirror (services.patexia.com, case id 181291) and Patsnap's litigation record (patsnap.com); I could not pull a CourtListener/RECAP docket image or a PACER printout for this case number, and only docket entries 1–14 are itemized in the sources available to me. Entries after 2023-05-03 (including the dismissal filing itself, likely Doc. 15) are established through the termination record rather than an entry-by-entry docket.

---

1. Filing and initial pleadings

2. Pre-trial motions of substance

None. There was no motion to dismiss, no § 1404(a)/§ 1406 transfer motion, no motion to stay pending IPR, no motion to compel arbitration, and no summary judgment motion. The only motions in the docket are procedural:

• 2023-04-28 — Doc. 10: Cedar Lane's Motion to Withdraw its own Doc. 8 Summons Returned Executed, plus Doc. 11 Request for Issuance of Summons and Doc. 12 re-issued Summons. In other words, Cedar Lane effectively conceded the September 2022 service on Vanguard was defective and had to be undone — the most consequential act in the case.
• The withdrawal is consistent with (though not expressly explained on the public docket) the defendant being Vanguard Integrated Solutions FZ-LLC of Dubai Internet City, UAE — a foreign entity not amenable to the ordinary domestic service Cedar Lane used. This causal link is my inference from the foreign-service docket entry below; the motion's text is not available to me.

3. Case-management pressure and foreign service

• 2023-04-26 — Doc. 9: Order to Show Cause (Albright, J.). The Court ordered Cedar Lane to explain, within one week, the absence of a "CRSR" and to show cause why the case should not be dismissed for want of prosecution, expressly warning it "may sua sponte dismiss this case without prejudice." This is roughly seven months after filing with no defendant appearance and no scheduling activity — the case was on the verge of being dismissed by the court.
• 2023-05-03 — Doc. 13: Status Report filed by Rabicoff in response (3 pp.), presumably explaining the service problem and the request for foreign service. I have not seen the text of this report.
• 2023-05-01 (entered 2023-05-08) — Doc. 14: "Documents received by Clerk's office for foreign service" with a confirmation attachment. Cedar Lane routed service through the Clerk's foreign-service channel toward the UAE. (Note: the UAE is not a Hague Service Convention member state, so this would have proceeded by letters rogatory/diplomatic channels; that is an inference, not a docket fact.) This is the cost-and-delay trap that ultimately killed the case: service abroad through the Clerk can consume a year or more and produces no answer, no Rule 26(f) conference, and no leverage.

No CCMS/scheduling order, no protective order, no ESI order and no discovery of any kind appears on the docket. Nothing was served, produced, or deposed. There is no strategic discovery milestone to report.

4. Claim construction (Markman)

Did not occur. No claim construction order, no Markman hearing, and no briefing. Cedar Lane never obtained a construction of "in response to the quantity of data in the memory" or "a rate determined by the processor system" — the two terms that would have driven the case.

5. Trial, verdict, post-trial motions

None. No trial setting, no verdict, no JMOL/Rule 59 motion, no fee motion under § 285. (Vanguard never appeared, so there was no fee litigation.)

6. Final disposition

• 2025-09-22 — Notice of Voluntary Dismissal Without Prejudice under Fed. R. Civ. P. 41(a)(1)(A)(i). The recorded termination text is verbatim:

  "Pursuant to Federal Rule of Civil Procedure 41(a)(1)(A)(i), Plaintiff hereby dismisses this action without prejudice. Defendant has not yet answered the Complaint or moved for summary judgment."

  Case closed the same day; basis of termination: voluntary dismissal. Because Rule 41(a)(1)(A)(i) permits dismissal as of right before the defendant serves an answer or moves for summary judgment, no court order was required and none issued — the notice itself terminated the action.

• No appeal — the case never produced a final judgment, and there was nothing to appeal.

• Present posture: closed. Cedar Lane's dismissal was without prejudice, so it preserved the ability to refile within the six-year damages lookback of 35 U.S.C. § 286. I found no evidence of a refiled action against Vanguard; treat any refiling as unverified.

Why Cedar Lane walked away: the '790 patent's estimated term expired 2023-08-01 (Patsnap bibliographic record — reflecting accumulated PTA over a 2000–2005 prosecution). By the time of dismissal the patent was expired, leaving only pre-expiration back damages against a Dubai-based integrator with a modest U.S. footprint, no U.S. counsel, and never validly served. The economics had collapsed.

7. Parallel PTAB proceedings

No IPR, PGR, or CBM proceeding against U.S. Patent No. 6,972,790 is recorded — Patsnap's validity-challenge field for '790 reads "None recorded," and my searches surfaced no PTAB trial involving the '790 patent or Cedar Lane. Consequently:

• There was no motion to stay pending IPR (nothing to stay for) and no PTAB estoppel of any kind.
• The '790 patent died by expiration, not by adverse PTAB or court ruling. It was never adjudicated valid or invalid, infringed or not infringed, in any forum.

(Flag: I could not complete a PTAB-side docket verification before finishing this analysis. The absence of an IPR is supported by the litigation database's validity-challenge record and by the absence of any stay motion in the docket, but should be confirmed against the USPTO PTAB docket if it matters to your purpose.)

Two record discrepancies you should note

1. Number of patents asserted. The Patsnap case record labels 6:22-cv-00968 as a "3 patents" case and lists both the '790 ("Host interface for imaging arrays") and '527 ("Module and method for interfacing analog/digital converting means and JPEG compression means") subject matter, whereas the case metadata for this analysis lists only 6,972,790. The likely explanation is that Cedar Lane's AO-120 report/related-case notice referenced its full three-patent family ('527, '790, '242) while the complaint asserted '790 — but this case-specific point is unverified. Per the operating instruction, I have treated '790 as the sole patent at issue.
2. Party name. The docket caption uses "Vanguard Integrated Solutions, Ltd."; the operating entity appears to be Vanguard Integrated Solutions FZ-LLC, Dubai Internet City, UAE (security/CCTV systems integrator). "Ltd." vs. "FZ-LLC" is very likely the root of the service defect that sank the case.

Structural read: this is a campaign data point, not a litigated case

Cedar Lane asserted '790 in 52 recorded cases (D. Del., D.N.J., W.D. Pa., N.D.N.Y., E.D.N.Y., W.D. Tex., W.D. Wash., N.D. Tex., W.D.N.Y.), and the outcomes cluster tightly: voluntary dismissal without prejudice (the modal result, often within 20–80 days of filing), occasional consent judgments (e.g., Vector Security, W.D. Pa., 2023, 62 days), and rare dismissals with prejudice (Zenitel, 6:22-cv-01307, 308 days; Opticon, D. Del., 327 days). Cedar Lane is a Canadian NPE on the Stanford NPE Litigation Database, category

I'll research this case and the plaintiff's counsel.

The docket shows one appearance so far. Let me verify whether additional counsel appeared later in the case and gather background on the firm/attorney.

Let me check the actual CourtListener/PACER docket for the full attorney list and any pro hac vice or local counsel entries.

I'll search for docket information and counsel appearances in this case.

Key signal: the docket may show no defense appearance at all. Let me verify against full docket sources.

Counsel of Record for the Defendant

Bottom line: no attorney ever appeared for Vanguard Integrated Solutions, Ltd. in this action. There is no defense counsel of record to identify.

This is not a case of sealed filings or a late appearance that the public record obscures — the docket affirmatively shows that the defendant never responded, and the case terminated on Cedar Lane's unilateral notice of dismissal before any defense entry of appearance could occur.

What the docket shows

Every substantive filing in No. 6:22-cv-00968 (W.D. Tex.) that appears in the free docket indexes was made by Plaintiff. The Patexia docket sheet for the case lists 14 entries total (Doc. 1 complaint through Doc. 14), and not one is a defense filing:

Source: Patexia docket — Cedar Lane Techs. Inc. v. Vanguard Integrated Solutions Ltd., No. 6:22-cv-00968.

Three structural signals confirm no appearance:

1. No answer, Rule 12 motion, or corporate disclosure statement ever appears. That is consistent with the recorded basis of termination, quoted verbatim in the litigation databases: "Pursuant to Federal Rule of Civil Procedure 41(a)(1)(A)(i), Plaintiff hereby dismisses this action without prejudice. Defendant has not yet answered the Complaint or moved for summary judgment." (Patsnap case record).
2. The plaintiff's own Rule 7.1/party record shows no defense counsel: Patsnap's "Counsel of record" field lists Isaac Rabicoff (Rabicoff Law LLC) for Cedar Lane and "Not recorded" for Vanguard. Likewise, the defendant's party page in the Stanford NPE Litigation Database contains no counsel information, and UniCourt/Justia entries for the case list only a "Plaintiff Attorney."
3. The service history explains the absence. Plaintiff took a default-eligible executed return in September 2022, then in April 2023 moved to withdraw that summons and re-issued process, after which the Clerk transmitted documents for foreign service — consistent with serving the Dubai-based Vanguard Integrated Solutions FZ-LLC through the Hague Convention rather than on a U.S. registered agent. Judge Albright's April 26, 2023 show-cause order (Doc. 9) threatening sua sponte dismissal for want of prosecution is the classic pattern in the Cedar Lane campaign's foreign-defendant cases, which were routinely abandoned rather than served.

Nothing to report on the defense side

• Lead counsel: none appeared.
• Local counsel (W.D. Tex.): none appeared.
• Of counsel / in-house: none identified. I found no public record of Vanguard retaining U.S. patent counsel, no firm press release or case-study page, and no Law360/Reuters coverage of the case (the dispute drew nothing beyond docket-aggregator and Patent Filings Roundup mentions, e.g., IPWatchdog's 9/23/2022 roundup listing the '790 filing).
• No defense-side motions, IPR petitions, or declaratory judgment action by Vanguard are recorded — Patsnap's patent record for US 6,972,790 reports "Validity challenges: None recorded."

Caveats and loose ends (flagged, not assumed)

• Docket completeness. The free docket indexes I could reach stop at Doc. 14 (May 2023). If any defense appearance was filed after that date, it is not reflected in the accessible record — and importantly, a Rule 41(a)(1)(A)(i) notice is only effective without a court order if the defendant has not yet served an answer or motion for summary judgment, which is exactly what the dismissal text recites. That recital is strong, but not conclusive, evidence that no appearance occurred.
• Closing-date discrepancy. Patsnap records closure on September 22, 2025 (1,102 days after filing), which sits oddly against a docket whose last visible entry is May 2023. September 22, 2025 is also the filing date of an unrelated Cedar Lane case (Cedar Lane Techs. Inc. v. Cantor Fitzgerald, L.P., No. 1:25-cv-07841 (S.D.N.Y.)). I could not independently verify the 2025 closing entry, so treat the precise termination date as database-derived rather than confirmed; the fact of a Rule 41(a)(1)(A)(i) dismissal without prejudice is corroborated by the quoted filing text.
• Do not conflate with the companion case. Cedar Lane also sued Vantage Integrated Security Solutions Pvt. Ltd., No. 6:22-cv-01062 (W.D. Tex.), a different Indian defendant, which was dismissed in May 2023 after its own show-cause order — also with no defense appearance of record. Any counsel name appearing in that docket should not be attributed here.
• This modifies one earlier inference. The prior section described the case as one where service problems "killed the case"; the docket supports that characterization (withdrawn summons, foreign-service transmittal, show-cause order, then Rule 41 dismissal), and adds the counsel-specific consequence: because no defense ever appeared, this case will have zero defense-side briefing, no invalidity contentions, and no local-counsel footprint to draw on — a materially different posture from the Cedar Lane matters that were actually litigated.
