Cedar Lane Technologies Inc. v. Vanguard Integrated Solutions Ltd.

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

Case Overview & Background

The parties. Plaintiff Cedar Lane Technologies Inc. is a Canadian non-practicing entity (NPE/PAE) incorporated in 2019 in Nelson, British Columbia, founded by Greg Benoit and funded on a patent-acquisition-plus-licensing model: it acquired the bulk of its portfolio — roughly 190+ U.S. patents, the great majority by assignment — from Intellectual Ventures and other sellers, and has filed several hundred infringement suits, making it one of the most prolific filers in the country (IAM reported it as the top-filing NPE of 2022, with a ~96% settlement rate among terminated cases; a Chinese IP-protection-centre risk alert counted ~325 suits and noted Cedar Lane was the most active patent plaintiff in the U.S. in 2021) — see https://www.iam-media.com/index.php/organisations/intellectual-ventures?sort=18&page=9 and http://www.sziprs.org.cn/szipr/hwwq/jfydzd/content/post_839930.html. Its near-exclusive counsel is Isaac Rabicoff of Rabicoff Law LLC (Alexandria, VA), who is the attorney of record here (Dkt. 2, Notice of Attorney Appearance, 9/16/2022). Note Cedar Lane and Rabicoff were sanctioned in 2020 by Judge Vince Chhabria (N.D. Cal.) for positions taken "in bad faith" in Cedar Lane Techs. v. Blackmagic Design — relevant background on the campaign's credibility (https://www.gadgetsgigabytesandgoodwill.com/2022/10/npe-showcase-cedar-lane-technologies/). Defendant Vanguard Integrated Solutions Ltd. is not an operating U.S. manufacturer but an integrator/supplier of IP-based physical-security products — network video/DVR-NVR recording systems, IP and traffic/ALPR cameras, video analytics, X-ray baggage scanners and access control — marketing itself as "the pioneer in IP-Based Integrated Solutions" (http://www.vanguard-is.com/technology_partners; https://securitybuyer.com/cnl-software-and-vanguard-integrated-solutions-form-technology-partnership/). Its corporate domicile is not clearly documented in public sources I could verify: a UK/London presence, a possible Canadian (Mississauga, Ontario) listing, and foreign-service activity on this docket are all consistent with a non-U.S. defendant — I flag domicile as unverified.

The technology and patents. The asserted family is Cedar Lane's standard "imaging" trio. The case metadata for this docket lists U.S. Patent No. 6,473,527; the docket's own AO-120/patent report and the Stanford NPE Litigation Database entries, however, show three patents asserted in 6:22-cv-00968 — the '527 patent plus U.S. Pat. Nos. 6,972,790 and 8,537,242 (https://npe.law.stanford.edu/patent/6473527; https://npe.law.stanford.edu/patent/6972790) — and third-party trackers likewise record three asserted patents and a Sept. 16, 2022 filing date (https://www.patsnap.com/resources/blog/litigation/cedar-lane-technologies-v-vanguard-integrated-solutions-imaging-ip-patsnap/). One-line sketches: '527 — "Module and method for interfacing analog/digital converting means and JPEG compression means," a FIFO/line-buffer interface that reads image lines from an A/D converter and feeds JPEG-sized 8×8 image blocks directly into a JPEG compressor's built-in memory so no extra frame buffer is needed; inventor Wang Chia-Ying, originally assigned to Mustek Systems Inc. (Taiwan), filed June 1, 1999, issued Oct. 29, 2002, and now expired (20-year term ran June 1, 2019), so only pre-expiration damages within the 35 U.S.C. § 286 six-year lookback are realistically recoverable (http://www.sziprs.org.cn/szipr/hwwq/jfydzd/content/post_839930.html). '790 and '242 — both titled "Host interface for imaging arrays" (Suska et al.), directed to an on-sensor interface that buffers imaging-array data and generates interrupt or bus-request signals to a host processor. The precise accused products are not verifiable from public sources: the complaints in this campaign incorporate claim charts by reference and describe accused instrumentalities generically ("products identified in the charts," typically cameras/DVRs/smartphones using JPEG compression and image-sensor interfaces); given Vanguard's catalog, the accused technology is almost certainly its IP cameras and DVR/NVR recording appliances, but I could not confirm the specific model list.

Procedural posture and significance. Filed September 16, 2022 in the W.D. Tex., Waco Division, before Judge Alan D. Albright — the venue and judge Cedar Lane used almost exclusively, and the same week it filed 16 cases there (see IPWatchdog's Patent Filings Roundup, Sept. 23, 2022, tagging Cedar Lane as an "[IV selloff]" asserter: https://ipwatchdog.com/2022/09/23/patent-filings-roundup-western-district-waters-tested-ip-edge-runs-disclosure-delaware/). Venue matters in two directions: Albright's docket was the preferred PAE forum (fast trials, Plaintiff-friendly procedures), and Cedar Lane's willingness to sue foreign defendants there tested both the court's reach and Rule 4/Hague Convention service — the docket shows exactly that friction. Vanguard was served on 9/23/2022 (Dkt. 8), but in April 2023 Cedar Lane moved to withdraw its returned summons and requested a new one (Dkts. 10–12), sent documents to the clerk's office for foreign service (Dkt. 14), and on April 26, 2023 Judge Albright issued an order to show cause why the case should not be dismissed for want of prosecution over the absence of the required case-readiness status report (Dkt. 9), prompting a status report (Dkt. 13). The case then went dormant for over two years and ended on September 22, 2025 with a Rule 41(a)(1)(A)(i) dismissal without prejudice — Cedar Lane's boilerplate recital that "Defendant has not yet answered the Complaint or moved for summary judgment" — so there is no merits ruling, no claim construction, and no damages record (dismissal text and docket via Patsnap, above, and https://services.patexia.com/lawsuits/Cedar-Lane-Technologies-Inc-v-Vanguard-Integrated-Solutions-Ltd-id-[181291](/patent/181291)/documents). It is notable chiefly as a data point in the NPE-pattern literature: a volume filer asserting expired and near-expiry image-processing patents against an overseas security-systems integrator, achieving a no-prejudice walk-away after three years rather than adjudication; no inter partes review or other PTAB validity challenge to the '527 patent appears in my searches (Patsnap records "validity challenges: none recorded"), and I found no Reuters/Law360/Unified Patents coverage of this specific docket — the reporting that exists is campaign-level rather than case-level.

I'll research this case systematically, starting with the docket, parties, and the patent at issue.

Initial results give me the outline. Now let me pull the full docket and check for PTAB activity.

The case appears to have been a service-only case that ended in voluntary dismissal. Let me verify the full docket and the patent's PTAB history.

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

Bottom line first

This case never became a contested patent case. It is a docket with a complaint, a defective service attempt, a Rule 41(a)(1)(A)(i) notice of voluntary dismissal without prejudice, and essentially nothing in between. There was no appearance by the defendant, no answer, no counterclaim, no motion practice by either side, no scheduling order, no Markman proceeding, no discovery, no trial, no judgment, and no appeal. The case terminated 2025-09-22, 1,102 days after filing, on Cedar Lane's own unilateral dismissal.

The only substantive events in the entire 36-month life of the case are (1) a service defect that Cedar Lane itself moved to withdraw, and (2) Judge Albright's order to show cause threatening sua sponte dismissal for want of prosecution. Both are procedural, but both are legally meaningful and are the real story here.

A caveat on sourcing up front: the docket-entry list I could verify by document number (Patexia docket, Doc. Nos. 1–14) runs only through 2023-05-08. The 2025 dismissal and the case's closure date come from the aggregated case record in Patsnap Litigation Data, which quotes the dismissal text verbatim. I could not independently pull the PACER image of the dismissal filing (likely Doc. No. 15 or later), and I did not locate a CourtListener/RECAP docket for this case number. Treat the final document number as unverified; treat the date and text as reliable but second-hand.

Note on the patent(s) at issue — a real conflict to flag

The case metadata for this report lists U.S. Patent No. 6,473,527 only. That patent is:

• Title: "Module and method for interfacing analog/digital converting means and JPEG compression means"
• Filed: 1999-06-01; granted: 2002-10-29
• Original assignee: Mustek Systems Inc. (Taiwan) — an acquired patent, consistent with Cedar Lane's Intellectual Ventures-derived portfolio
• Claim 1 is a means-plus-function claim ("read control means," "memory means," "output control means"), which is where the infringement case would have been fought had it survived

Third-party databases, however, report three patents in this docket — typically the Cedar Lane trio '527, 6,972,790 ('790) and 8,537,242 ('242). Patsnap's case page says "The docket lists 3 asserted patents," and its FAQ identifies the '790 as asserted; IPWatchdog's 2022-09-23 filings roundup likewise lists 6,972,790 for this case number, while the Stanford NPE database indexes this case under the '527. Both patents appear on the same Patsnap case record, and the AO 120 practice in Cedar Lane's parallel W.D. Tex. complaints listed all three.

Practical read: Cedar Lane's standard 2022 W.D. Tex. complaint template asserted the family together, so the docket almost certainly referenced all three; the operative asserted patent per your metadata is the '527. Because the defendant never answered and no infringement contentions were ever served, no court ever narrowed the assertion to specific claims or patents. This discrepancy was never resolved by any ruling and cannot be resolved from the record — flagging it rather than papering over it.

Term: The '527 is expired. One source puts expiration at 2019-06-01 (20 years from the 1999-06-01 filing), while Patsnap lists an estimated expiry of 2023-08-01, implying a substantial patent term adjustment. I could not reconcile these, and the underlying USPTO term calculation was not reviewed. Either way, the patent was expired, or imminently expiring, throughout this litigation — which matters a great deal to the strategy discussion below.

Chronological development

I'll research the counsel of record for Cedar Lane Technologies in this case.

Counsel of Record for Plaintiff Cedar Lane Technologies Inc.

Bottom line: Only one attorney appears for the plaintiff on this docket — Isaac P. Rabicoff of Rabicoff Law LLC, who filed the complaint and every subsequent plaintiff-side paper himself. No local counsel, no co-counsel, and no in-house counsel appear on the docket, and no other Rabicoff Law attorney (e.g., Kenneth Matuszewski, his usual PTAB backup counsel) entered an appearance in this case.

Appearance Table

Docket support for the identification

• Dkt. 1 – Complaint for Patent Infringement, filed 9/16/2022 (Rabicoff, Isaac), assigned to Judge Alan D. Albright, Waco Division.
• Dkt. 2 – Notice of Attorney Appearance by Isaac Rabicoff on behalf of Cedar Lane Technologies Inc. (9/16/2022).
• Dkt. 3 – Rule 7 Disclosure Statement; Dkt. 4 – Summons request; Dkt. 5 – AO 120 Patent/Trademark Form; Dkt. 6 – Notice of Related Case (all Rabicoff, 9/16/2022).
• Dkt. 8 – Summons Returned Executed (service on Vanguard 9/23/2022); Dkt. 10 – Motion to Withdraw the Summons Returned Executed; Dkt. 11 – Request for Issuance of Summons; Dkt. 13 – Status Report (all Rabicoff).
• Dkt. 9 – Court's Order to Show Cause (4/26/2023) requiring plaintiff to explain the absence of a completed case-readiness/scheduling report and why the case should not be dismissed for want of prosecution.
• Termination: voluntary dismissal without prejudice under Fed. R. Civ. P. 41(a)(1)(A)(i) on 9/22/2025, plaintiff expressly noting that "Defendant has not yet answered the Complaint or moved for summary judgment." No defendant-side counsel ever appeared; the case never reached answer, Markman, or trial.

Practice notes relevant to the representation

• Rabicoff is the architect of Cedar Lane's nationwide campaign (Cedar Lane is a Canadian NPE incorporated in 2019 that acquired much of its portfolio from Intellectual Ventures entities; it was the top-filing patent plaintiff in 2022). This case is one of the September 2022 wave of W.D. Tex. filings.
• Credibility flag worth carrying forward: in a 2020 N.D. Cal. matter, Judge Vince Chhabria sanctioned both Cedar Lane and Mr. Rabicoff for taking "objectively frivolous" positions "in bad faith," noted he was "a serial filer of patent lawsuits in the Northern District of California [but] is not admitted to practice in this district," and referred him to that court's Standing Committee on Professional Conduct (as reported by Seyfarth Shaw's "NPE Showcase" and Mondaq). I could not independently pull the underlying order in this research pass, so treat the case citation as unverified.
• On the merits of opposing him: Cedar Lane cases overwhelmingly terminate before or at the pleadings stage via voluntary dismissal or modest settlement — the company has no trial history. Cedar Lane's patents in this family have also been targeted in PTAB proceedings, though none against the '527 patent specifically were located.

Sourcing caveats — please read

1. I could not access PACER directly. The docket entries above are drawn from third-party RECAP/aggregator mirrors (Patexia's docket render for case id 181291, Patsnap Litigation Data, UniCourt, and Stanford's NPE Litigation Database). The document list I could retrieve ends in mid-2023; the 2025 dismissal is reported by Patsnap but I did not see the dismissal paper's docket number. Verify Dkt. 15+ and the dismissal entry on PACER before citing.
2. Pro hac vice status is unconfirmed. Mr. Rabicoff is not shown as Texas-admitted. No pro hac vice motion appears in the document list I could retrieve, which may simply be a gap in the aggregator data rather than reality. I could not confirm whether he was admitted pro hac vice in W.D. Tex. for this case, or whether (as some high-volume filers do) an unlisted local counsel was quietly engaged. This is the one open question I would resolve with a direct PACER docket pull.
3. Nothing here is sealed — there is no indication of sealed filings or of counsel who has not yet appeared; the plaintiff's side, at least, is fully on the record.
4. Minor discrepancy worth noting: case metadata lists only U.S. Patent No. 6,473,527, while the complaint/docket data indicate three patents asserted — 6,472,527, 6,972,790, and 8,537,242 (the '790 and '242 patents are both titled "Host interface for imaging arrays").

I'll research the docket and counsel for the defendant in this case.

Let me verify against the actual docket via CourtListener/RECAP and check for any defendant appearances.

Let me check the CourtListener RECAP docket directly and look for any defense-side appearances.

Bottom line

No attorney ever entered an appearance on behalf of Vanguard Integrated Solutions Ltd. in this case. The docket for Cedar Lane Technologies, Inc. v. Vanguard Integrated Solutions, Ltd., No. 6:22-cv-00968-ADA (W.D. Tex.) contains no defense-side notice of appearance, no answer, no Rule 12 motion, no corporate disclosure statement, and no counsel designation — and the case was ultimately terminated by the plaintiff's unilateral notice of dismissal under Rule 41(a)(1)(A)(i) on the express representation that the defendant "has not yet answered the Complaint or moved for summary judgment."

So the honest answer to "identify defendant's counsel of record" is: there are none to identify. I am not going to name attorneys who do not appear in the record.

What the record actually shows

Docket sources: Patexia Research docket/document list for No. 6:22-cv-00968 (https://services.patexia.com/lawsuits/Cedar-Lane-Technologies-Inc-v-Vanguard-Integrated-Solutions-Ltd-id-181291/documents); PatSnap litigation record with the verbatim Rule 41 dismissal text (https://www.patsnap.com/resources/blog/litigation/cedar-lane-technologies-v-vanguard-integrated-solutions-imaging-ip-patsnap/); Stanford NPE Litigation Database, party page for Vanguard Integrated Solutions Ltd. (https://npe.law.stanford.edu/party/vanguard-integrated-solutions-ltd); Justia docket index (https://dockets.justia.com/search?parties=Integrity%20Solutions%2C%20Ltd.).

The one attorney who did appear (plaintiff side, for contrast)

• Isaac Rabicoff — sole attorney of record; Rabicoff Law LLC (Chicago-based; the firm is Cedar Lane's captive/regular counsel and Rabicoff is Cedar Lane's long-running enforcement lawyer, having filed well over 300 Cedar Lane suits across W.D. Tex., D. Del., D.N.J., S.D.N.Y., N.D. Ill., and elsewhere). He is the only name on the docket (Docs. 2, 3, 4, 5, 6, 10, 11, 13).

This matters analytically: in Cedar Lane's campaign, the absence of any defense appearance is the norm in the tail cases. Cedar Lane's pattern is mass-filing, then Rule 41(a)(1)(A)(i) dismissal without prejudice once service stalls or a license is negotiated — a pattern visible in sibling cases such as Cedar Lane v. Vantage Integrated Security Solutions Pvt. Ltd., No. 6:22-cv-01062 (W.D. Tex.), dismissed 5/30/2023 after a nearly identical OSC sequence.

---

Caveats I want to be explicit about

1. I could not pull the PACER docket sheet directly, so my docket reconstruction relies on secondary aggregators (Patexia, PatSnap, Justia, Stanford NPE) plus the verbatim dismissal language quoted by PatSnap. The Patexia listing appears to stop at Doc. 14 (May 2023) and does not display the September 2025 dismissal entry; the dismissal itself is corroborated by two independent aggregators, but I have not seen the actual ECF image of that notice.
2. Sealed filings: nothing in the record I reviewed suggests sealed defense filings. The absence of counsel is not a sealing artifact — it is confirmed affirmatively by the plaintiff's Rule 41 certification that no answer or dispositive motion was ever filed.
3. Counsel may have existed off-docket. Vanguard could well have retained U.S. or foreign counsel for pre-suit licensing talks, Hague Convention service correspondence, or settlement discussions without ever entering an appearance. I have no source for any such retention, and I will not speculate as to names or firms.
4. No IPR activity verified. I found no PTAB petition by Vanguard against the '527 patent; Cedar Lane's asserted patents (including U.S. Pat. 6,473,527) show no recorded validity challenges in the litigation databases I checked. Treat that as "not found," not as a confirmed negative.
5. Patent-scope discrepancy worth flagging: the case metadata I was given lists only U.S. Pat. 6,473,527, but PatSnap's record for this docket states three patents were asserted, including U.S. Pat. 6,972,790 ("Host interface for imaging arrays"). The Stanford NPE database confirms the '527 and '790 patents were both asserted against Vanguard in this action. The existing case summary's "family-level listing" appears to understate the asserted set.

Practical takeaway

For any counsel-of-record table or litigation-history narrative, this case should be coded as "defendant unrepresented / no appearance" — a service-and-dismissal case, not an adversarial one. There is no defense privilege to waive, no defense fact discovery, no defense expert, and no defense-authored briefing. The only reasoned judicial act in 1,102 days was Judge Albright's April 26, 2023 show-cause order directed at the plaintiff for failing to prosecute.
