Case Overview: Cedar Lane Technologies Inc. v. Lorex Technology Inc., No. 6:22-cv-00654 (W.D. Tex.)

The parties. Cedar Lane Technologies Inc. is a Canadian patent-assertion entity headquartered in Nelson, British Columbia, formed in 2019 to acquire and enforce patents — much of its portfolio traced to Intellectual Ventures/AvInnov — and it was, by several accounts, the single most prolific patent plaintiff in the United States in 2022, with IAM reporting that it "filed the most cases in 2022," strongly favored the Western District of Texas, and achieved a ~96% settlement rate among terminated cases (IAM, Mar. 20, 2023; Seyfarth NPE Showcase). Cedar Lane does not make or sell products. Its litigation is handled principally by Isaac Rabicoff of Rabicoff Law LLC, and its cases almost never reach claim construction, let alone trial. Lorex Technology Inc. is the Canadian-headquartered, North America–facing consumer and prosumer video-security brand — a top-selling U.S./Canadian camera brand sold through Costco, Amazon, Best Buy, Home Depot, Lowe's and Walmart — whose corporate history is unusually eventful: owned by FLIR Systems until FLIR sold it to Dahua Technology for ~$29M in February 2018, then sold by Dahua to Taipei-based Skywatch for ~$72M (announced November 24, 2022, one day before the FCC issued its Dahua equipment order), while remaining dependent on Dahua as its OEM component supplier (Security Sales & Integration, Feb. 6, 2018; Dahua press release, Nov. 24, 2022; Iowa AG complaint). Lorex is separately the target of state AG consumer-protection actions (Nebraska, filed Sept. 23, 2025; Iowa; Texas) over its Dahua ties and camera vulnerabilities (Nebraska AG release). The accused instrumentality here is Lorex's internet-connected security camera and NVR product line — specifically, per the campaign's uniform pleading template, the image-sensor-to-host-processor interface architecture inside those devices. Caution: the complaint itself does not name any model or product in its body; it refers to "Exemplary Defendant Products" identified only in Exhibits 3 and 4, which were not filed with the complaint, and pleads only conclusory infringement (complaint analysis, 6:22-cv-00654). The product identification above is an inference from the patents' subject matter and the parallel complaints in Cedar Lane's identical 2022 filings, not something the docket establishes.

The patents. Both patents share one specification and one inventor (Mark Suska), one priority date (January 21, 2000), and one title — "Host interface for imaging arrays" — and are asserted as an apparatus/method pair. U.S. Patent No. 6,972,790 (filed Dec. 21, 2000; issued Dec. 6, 2005; prosecuted by McAndrews Held & Malloy; examiner Thai Tran, Art Unit 2612) claims an on-chip interface that decouples a CMOS image sensor's rigid, continuous pixel-output clock from a host processor's asynchronous bus: a FIFO (or addressable) memory buffers image data at the sensor's rate, and a signal generator — responsive to the quantity of data in the memory — asserts an interrupt or bus request so the processor can drain the buffer at its own pace, eliminating glue logic. U.S. Patent No. 8,537,242 (issued Sept. 17, 2013) is a divisional of the '790 application that claims the same architecture as a method: receive and store image data in a FIFO, update a FIFO counter, compare the count to a FIFO limit, and generate a processor interrupt when a "predetermined relationship" is met. The '242 is reported to be subject to a terminal disclaimer over the '790, tying the two to a common term. Critically, the '790 is reported by Patsnap as having an estimated expiry of August 1, 2023 (December 21, 2000 filing date plus patent term adjustment), and Patsnap records its status as inactive with no validity challenges recorded (Patsnap patent record). In other words, both asserted patents lapsed within roughly seven months of this case's dismissal, which caps any damages tail and largely explains why the campaign generated settlements rather than judgments.

Posture, venue, and why it matters. Cedar Lane filed on June 23, 2022 in the Waco Division of the Western District of Texas (the "6:" divisional prefix denotes Waco), where the case was assigned to Chief Judge Alan D. Albright — then the most active patent judge in the country and the reason Cedar Lane and other mass filers concentrated there. Cedar Lane dismissed the case with prejudice under Fed. R. Civ. P. 41(a)(1)(A)(i) on January 9, 2023, before Lorex answered or moved for summary judgment, with each side bearing its own costs — 200 days from filing (Patsnap case record; defendant's counsel of record appears in the docket-derived record as Keana Theresa Taylor of Upshaw Uhrich Taylor & Dykema PLLC). The docket does not state a reason for dismissal; the timing — five months after Cedar Lane sued, and weeks after Dahua announced the Lorex/Skywatch sale and the FCC acted against Dahua equipment — is suggestive but unsourced as a cause. This case is notable less as a dispute than as a data point in three patterns. First, it is one of a dense cluster of near-simultaneous suits Cedar Lane filed against security-camera and imaging OEMs in 2022 on these same two patents — the Stanford NPE Litigation Database lists 20+ cases on the '790 alone, spanning end-product sellers (Hanwha Techwin, IDIS, March Networks, Dallmeier, Silent Sentinel, Lore

Counsel of Record for Plaintiff Cedar Lane Technologies Inc.

Bottom line: Only one attorney appeared for Cedar Lane in this action — Isaac Phillip Rabicoff of Rabicoff Law LLC (Chicago). There is no local-counsel entry, no second firm, and no in-house counsel on the docket. The case was dismissed voluntarily with prejudice on January 9, 2023, before Lorex answered, so the appearance list never grew beyond the plaintiff-side filing attorney.

1. Isaac Phillip Rabicoff — sole/lead counsel of record

Field Detail
Role Lead (and only) counsel of record for Plaintiff Cedar Lane Technologies Inc. Signed the complaint and all plaintiff-side filings.
Firm Rabicoff Law LLC — a small, plaintiff-side patent-enforcement boutique; Mr. Rabicoff is the firm's founder/principal.
Office Chicago, Illinois. During the 2022 filing period the firm's address in Cedar Lane pleadings was 73 W. Monroe St., Chicago, IL 60603; the firm has since listed 4311 N. Ravenswood Ave., Suite 315, Chicago, IL 60613, and at times has also used Washington, D.C.-area addresses (Arlington, VA; Alexandria, VA). Phone (773) 669-4590; isaac@rabilaw.com.
Bar/admission note Frequently appears pro hac vice outside Illinois; admission status in the W.D. Tex. bar for this specific case is not confirmed in the sources I could retrieve (see caveats below).

One-line experience note: Rabicoff is Cedar Lane's near-exclusive outside counsel and one of the highest-volume patent filers in the country — Chinese IP-protection bulletins tracking Cedar Lane put him at roughly 58 Cedar Lane cases and the Stanford NPE database lists dozens of Cedar Lane suits (mostly W.D. Tex. and D. Del.) under his signature. His practice is volume enforcement rather than trial work: Cedar Lane cases characteristically resolve by early voluntary dismissal or modest settlement, and none has gone to trial.

Also relevant to his profile (well documented): In Cedar Lane Technologies Inc. v. Blackmagic Design Inc., No. 20-cv-01302-VC (N.D. Cal.), Judge Vince Chhabria sanctioned Rabicoff $1,000 under Rule 11 and the court's inherent authority on Nov. 19, 2020, finding frivolous arguments and misrepresentations, denied his pro hac vice motion, and referred him to the N.D. Cal. Standing Committee on Professional Conduct (No. 20-mc-80206-JD). The Committee's final report resolved the matter through an informal agreement under which Rabicoff paid ~$9,193 in unpaid pro hac vice fees by February 28, 2022 and agreed to prospective compliance. This is directly on point for gauging the caliber and posture of the counsel behind this docket.

2. What is not on the record

  • No local counsel. Unlike many W.D. Tex. patent cases, no Texas firm entered an appearance for Cedar Lane here. If any local counsel was engaged, it never appeared of record before dismissal.
  • No in-house counsel. Cedar Lane is an NPE holding entity (incorporated in Canada in 2019) with no in-house legal department appearing in these suits. Its founder, Greg Benoit, is described in secondary reporting as an attorney with NPE-litigation background and is the company's principal — but he is not an attorney of record in this case, and I found no filing signed by him.
  • No sealed or deferred appearances. Nothing in the docket record suggests a sealed appearance; the case simply closed early. (For completeness, defendant Lorex was represented by Keana Theresa Taylor of Upshaw, Uhrich, Taylor & Dykema PLLC.)

3. Sourcing and confidence

Defendant representatives

Counsel of record for the defendant(s): attorneys, firms, and roles (lead counsel, of counsel, local counsel).

I'll research the counsel of record for Lorex Technology in this case.

Counsel of Record for Lorex Technology Inc. — 6:22-cv-00654 (W.D. Tex.)

Bottom line first (important caveat)

This case never reached an appearance stage. Cedar Lane filed the complaint on 23 June 2022 and then, on 9 January 2023, dismissed the action with prejudice by notice under Fed. R. Civ. P. 41(a)(1)(A)(i). The dismissal notice states on its face that "Defendant has not yet answered the Complaint or moved for summary judgment." Consistent with that, docket-aggregator summaries of the case (e.g., the Ex Parte AI docket abstract) show the defendant entry as "No Attorneys" recorded. So there is no Notice of Appearance, no pro hac vice application, no Rule 7.1 disclosure, and no answer from Lorex in the public docket of this case.

The only attorney I could associate with the defense is from a secondary litigation-data source (Patsnap's case record for 6:22-cv-00654), which expressly states: "Isaac Rabicoff is recorded as counsel for plaintiff Cedar Lane Technologies. Keana Theresa Taylor appears for defendant Lorex." I could not confirm that attribution against a PACER docket entry, and I have flagged it as unverified below rather than presenting it as a docket fact.

Attorney identified for Lorex

Field Detail
Name Keana Theresa Taylor
Role Only attorney attributed to Lorex in the case record; effectively lead/defense counsel of record (no local counsel or co-counsel identified)
Firm Upshaw Uhrich Taylor & Dykema PLLC (per the case record); the firm was formerly styled Upshaw PLLC, 1204 Gano Street, Dallas, TX 75215
Office Dallas, Texas (firm; Taylor's current practice address, per later filings, is Taylor Dykema PLLC, 914 E. 25th St., Houston, TX 77009)
Admissions Texas State Bar No. 24042013 (admitted 2003); registered to practice before the USPTO; admitted in E.D. Tex. and the Federal Circuit; Tulane J.D. 2003
Experience note Career patent litigator who has served as Texas counsel for ZTE (USA) Inc. and ZTE (TX) Inc. in Fractus, S.A. v. ZTE Corp. (E.D. Tex. 2:17-cv-00561), Super Interconnect Technologies LLC v. ZTE Corp. (N.D. Tex. 3:18-cv-02932) and Cypress Lake Software, Inc. v. ZTE (USA) Inc. (N.D. Cal. 5:18-cv-06146), and for Quantile Technologies Ltd. in TriOptima AB v. Quantile Technologies Ltd. (E.D. Tex. 2:19-cv-00390) — i.e., a defense-side patent docket, including non-U.S. and hardware/electronics clients.

Caveat / sourcing: The attribution to Ms. Taylor comes solely from an aggregated "Parties of record / Counsel" field (Patsnap Litigation Data, which states attorney names "appear as recorded in the docket"). It is plausible and internally consistent — Lorex is a Canadian consumer-security-camera company, and this firm handled comparable camera/electronics defendants in Cedar Lane's parallel W.D. Tex. and D. Del. wave of 2022 filings — but it is not corroborated by any docket entry I could locate. Treat it as likely but unverified.

Attorneys I could not confirm (do not assume)

  • Erik J. Dykema (Taylor's partner; Upshaw PLLC / now Taylor Dykema PLLC) — repeatedly co-counseled with Taylor in the ZTE matters, but no evidence he appeared for Lorex here.
  • Everett M. Upshaw, Craig L. Uhrich — same firm; no evidence of appearance in this case.
  • Any in-house Lorex counsel — Lorex (Markham, Ontario) is privately held and I found no record of in-house litigation counsel participating.
  • Any W.D. Tex. local counsel — none recorded; unsurprising given the 200-day, pleadings-only life of the case.
  • Any pro hac vice counsel — none recorded.

Filings status

Nothing in this case was sealed or under seal so far as the record shows; the reason counsel information is thin is simply that the case was dismissed before the appearance deadline was triggered, not because of sealing.

For contrast — plaintiff's counsel (verified)

Isaac Phillip Rabicoff, Rabicoff Law LLC (Chicago, IL), sole and frequent counsel of record for Cedar Lane Technologies across its assertor campaign, including this filing. This is the only counsel confirmed on the face of the docket.

Recommended verification step

If you need a citable, court-record confirmation of Lorex's counsel, pull the PACER docket sheet for 6:22-cv-00654 (W.D. Tex.) and check for (a) a Notice of Appearance or (b) any correspondence/extension request filed between July 2022 and January 2023 — extensions of time to answer are the most likely place a defense appearance would surface in a case that died before an answer. Absent such an entry, the correct statement in any filing is that Lorex made no appearance of record in this action.
