Cedar Lane Technologies Inc. v. TCL Communication

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

Case Overview — Cedar Lane Technologies Inc. v. TCL Communication, Inc., No. 1:20-cv-00836-CFC (D. Del.)

Parties. Cedar Lane Technologies Inc. is a non-practicing entity organized under the laws of British Columbia, Canada (principal place of business listed in later complaints as 560 Baker Street, Suite 1, Nelson, BC), with no parents or affiliates disclosed in its Rule 7.1 statement (D.I. 4). It is the archetypal acquisition-based assertion vehicle of the 2020–2023 wave: Chinese IP-protection authorities describe it as "a typical NPE" registered in Canada in 2019, founded by Greg Benoit (a lawyer with NPE-litigation background), holding roughly 193 U.S. patents of which about 191 were acquired rather than developed in-house, and by Lex Machina's count the single most prolific patent plaintiff in the United States in 2021, with 325+ federal suits naming Huawei, MediaTek, Apple, and TCL among others (Shenzhen IP Protection Center risk advisory, Feb. 2023). Cedar Lane's counsel of record in this suit was Raeann Warner as Delaware local counsel (D.I. 1); its high-volume national counsel in the later W.D. Tex./D. Del. waves was Isaac Rabicoff of Rabicoff Law LLC — I did not confirm Rabicoff's appearance in this docket. Defendant TCL Communication, Inc. is the U.S. operating subsidiary of the Chinese handset group TCL Communication Technology Holdings (TCL/Alcatel-branded phones and tablets); it is an operating company, not an NPE, and Delaware venue rested on its Delaware presence and U.S. sales.

The technology and accused products. The asserted family is not about phone features at the user-interface level but about the camera pipeline: the interface between a CMOS/CCD imaging array and a host microprocessor. U.S. Patent No. 6,972,790, "Host interface for imaging arrays" (filed Dec. 21, 2000; issued Dec. 6, 2005; inventor Mark Suska; original assignee Psion Teklogix Systems Inc.; priority Jan. 21, 2000; now Cedar Lane), claims an interface — preferably integrated on the same die as the sensor — containing a memory (e.g., a FIFO) that stores imaging-array data at the sensor's clock rate, a signal generator that asserts an interrupt or bus request to the processor "in response to the quantity of data in the memory," and a circuit that then lets the processor drain the buffer at its own pace. Independent claim 1 is the representative system claim; the patent's stated problem is the "glue logic" cost of bridging a sensor's rigid, continuous output with an asynchronous microprocessor bus. In the companion complaint language used across Cedar Lane's campaign, the accused instrumentalities were charted as camera-equipped TCL/Alcatel handsets containing sensor-plus-buffer host interfaces. The public complaint does not itself name model numbers — infringement contentions were carried in claim-chart exhibits (Exhibits 9a–16c) — and I could not verify specific TCL model numbers from the public record, so treat the product identification as inferred rather than confirmed. One sourcing caveat: your case metadata lists only the '790, but the Rule 3/AO-120 patent report filed at D.I. 3 lists five patents (6,473,527; 6,516,147; 6,566,805; 6,972,774; 6,972,790) and the exhibit structure plus third-party docket aggregators indicate the complaint may have asserted as many as eight (adding 7,292,261, 8,165,867, and 8,537,242). The '790 is the case's anchor patent and the one with the clearest public technical record; I have not independently verified titles/scope for '774, '261, '805, or '147, so I have not sketched them.

Procedural posture and why it matters. Filed June 22, 2020 in the District of Delaware and assigned to Judge Colm F. Connolly (D.I. 1, 5; case assignment June 24, 2020). TCL was served June 24, waived service July 14, and, on a consent motion filed by Cedar Lane itself, obtained an extension of its answer deadline to October 13, 2020 (D.I. 6, 7, 8; order July 16, 2020). As of late October 2020 the case was reported as still "in the pleadings stage" alongside Cedar Lane's Arrow Electronics and WPG Americas suits, in an article noting that other Cedar Lane cases had drawn show-cause orders for failure to prosecute (Mondaq, Oct. 26, 2020). Docket aggregators now show the case as closed; I could not verify the terminating entry or date from a primary source in this pass — the strong pattern across Cedar Lane's docket is early voluntary dismissal or consent judgment (Patsnap's litigation record for the '790 shows dozens of its 52 tracked cases ending in voluntary dismissal, typically within 20–350 days), so a quick negotiated exit is the likely disposition, but it should be confirmed against PACER before being stated as fact. Delaware mattered here for two reasons: it was Cedar Lane's preferred 2020 forum (a coordinated wave of dozens of Judge Connolly cases filed in April–June 2020, including OmniVision and Drift Innovation) and it offered a defendant-side counterweight that, together with § 101 motion practice, helped push Cedar Lane's later waves to W.D. Tex. before Judge Alan Albright.

Why the case is notable. Three reasons. First, it is a specimen of the "expiring-pipeline patent" campaign: the '790 and its divisional '242 carried an estimated expiry of August 1, 2023, which both compressed the damages window under 35 U.S.C. § 286 and explains the 2020–2023 filing surge — the '790 alone has been asserted in roughly 52 tracked cases against handset makers, security-camera vendors, dashcam/robotics companies, automakers, and even rental-car and banking defendants. Second, the campaign targeted the supply chain, not just brands: Cedar Lane sued sensor and chip vendors (OmniVision, ON Semiconductor, MediaTek, STMicroelectronics, Renesas, Socionext, PixArt) as well as OEMs like TCL, which is why a handset maker's exposure here was partly derivative of its image-sensor sourcing. Third, the IPR/validity linkage is asymmetric and worth flagging: Unified Patents ran a PATROLL crowdsourcing contest on Cedar Lane's U.S. 8,165,867 — a patent Unified notes was asserted against TCL Communication among others — but Patsnap's record for the '790 shows no PTAB validity challenge, meaning the most-asserted asset in the portfolio generated settlements without ever being tested at the Board.

Sourcing notes. Docket facts (filing date, judge, D.I. 1/3/4/6/7/8, extension to Oct. 13, 2020) are from the Justia, UniCourt, and CourtListener RECAP dockets for 1:20-cv-00836. Party/NPE characterization and portfolio counts are from the Shenzhen IP Protection Center advisory (Feb. 2023) and Patsnap's '790 litigation record. Patent technical content is from the '790 specification/claim 1 as quoted in public complaint analyses of parallel Cedar Lane suits (Ex Parte AI Lab summaries; the Alps Alpine complaint on CourtListener). Not verified: the exact terminating entry for this docket; TCL model numbers; whether 7,292,261 and 8,165,867 were in fact asserted in this complaint as opposed to a later TCL-related filing; and counsel-of-record beyond Ms. Warner.

I'll research this case across docket sources, PTAB records, and legal press. Let me start with several searches in parallel.

Let me get the full docket from CourtListener and check for the case's disposition.

Caveat on the record

This case is thinly documented in public sources. Defendant TCL Communication is a Chinese-affiliated entity, the case sat in a Delaware pleadings posture, and — like essentially all Cedar Lane matters — it terminated before any substantive motion practice or Markman. Below I separate what is docket-verified from what is inference. I was unable to retrieve a PACER docket entry showing the termination date or the basis of dismissal for 1:20-cv-00836; the aggregators report the case as "Closed" without a disposition entry. Treat the final-disposition paragraph accordingly.

Case identity and the patent

The '790 claim 1 covers an interface (preferably on the image-sensor die) with (a) a memory storing imaging-array data and clocking signals at the clock's rate, (b) a signal generator producing an interrupt/bus-request "in response to the quantity of data in the memory," and (c) a circuit transferring data out at a rate set by the processor. The natural non-infringement battleground — never reached here — is whether the accused camera/SoC pipeline triggers on data quantity (FIFO high-water mark) versus end-of-line/end-of-frame events.

Chronology

2020-06-22 — Complaint (Dkt. 1). Jury demand; 35 U.S.C. § 271; 28 attachments including 16+ claim-chart exhibits (Exs. 1–16c), Civil Cover Sheet. Filed alongside Dkt. 2 (magistrate consent forms), Dkt. 3 (Patent/Trademark Report), Dkt. 4 (Rule 7.1 disclosure — "No Parents or Affiliates Listed"), Dkt. 5 (summonses). The complaint pleaded direct infringement plus induced infringement (relying on product literature/website materials instructing end users) and post-service knowledge allegations for the '790 and '242 patents, but did not plead a separate willfulness count. (Justia docket; UniCourt)

2020-06-24 — Service on TCL Communication; answer due 2020-07-15 (Dkt. 6, filed 2020-07-02).

2020-07-14 — Waiver of service sent; answer reset to 2020-09-14 (Dkt. 7).

2020-07-15 / 2020-07-16 — Extension. Cedar Lane (not TCL) filed the consent motion (Dkt. 8) extending TCL's response deadline to 2020-10-13; Judge Connolly so-ordered it on 2020-07-16. (Significant only in that plaintiff-driven extensions are the signature of a fee-driven, settlement-oriented campaign rather than a merits fight.)

Answer / counterclaims. No answer, counterclaim, or Rule 12 motion is reflected in any public source I could retrieve. The last docket activity captured by the aggregators is the July 2020 extension, and the databases independently code the case as terminated. The metadata's "pleadings stage as of Oct. 2020" is consistent with a case that never got past the answer deadline.

No pre-trial motions of substance. No motion to dismiss, § 1404(a) transfer motion, motion to stay pending IPR, or summary-judgment motion appears in the record. Notably, TCL did not seek transfer out of Delaware despite the absence of any Delaware nexus — an unusual omission for a Chinese handset maker, and consistent with a decision to resolve commercially rather than litigate.

No Markman, no discovery of consequence, no trial. No scheduling order, no § 282 disclosures, no claim-construction briefing, no verdict, no JMOL/new-trial/fee motion. Because the case died in its first months, none of the substantive issues the '790 presents (claim 1's "in response to the quantity of data," the dual data-plus-clocking-signal storage limitation, divided/induced infringement for chip-level components sold into third-party handsets) were ever adjudicated.

Termination. Aggregator records code 1:20-cv-00836 as "Closed" with no recorded basis of termination, and no reported judgment, consent judgment, injunction, or damages award. (Ex Parte case record) Given the campaign-wide pattern described below, the overwhelmingly likely mechanism is a Rule 41(a)(1)(A)(i) voluntary dismissal, probably with prejudice and with each side bearing its own fees, following an out-of-court license/payment — but I am flagging this as inference, not docket fact. Counsel should pull the full PACER docket for the exact entry.

The parallel TCL action — the more important proceeding

Cedar Lane did not stop with the 2020 Delaware case. On 2021-04-26 it filed Cedar Lane Technologies Inc. v. TCL Corporation, No. 6:21-cv-00408 (W.D. Tex.) — a second suit against the TCL corporate parent in Judge Alan Albright's courtroom, which by 2021 had become Cedar Lane's preferred venue. (Patexia related-case table) I could not retrieve that case's docket or disposition within search limits, but the second filing's existence is itself the strategic signal: the D. Del. case was abandoned as a negotiating lever, not litigated to judgment.

---

Parallel PTAB proceedings on the '790

I found no IPR, PGR, or CBM petition against U.S. 6,972,790. The Patsnap litigation record for the patent expressly lists "Validity challenges: None recorded" across its 52 tracked district-court cases (link). That is a striking — and strategically diagnostic — fact:

• Cost/benefit: an IPR costs $300k–$500k+; Cedar Lane settles in a median of ~77 days for the Shenzhen-defendant cohort. No rational defendant buys an IPR to kill a case that will settle for less.
• Timing: the '790's nominal 20-year term ran from 2000-12-21, i.e., 2020-12-21, extended by PTA to 2023-08-01. By the time an IPR could be instituted and appealed, the patent would have expired — destroying the injunction value that drives IPR economics, though not past-damages exposure (§ 286 six-year lookback).
• Claim structure: claim 1's "memory for storing … clocking signals" limitation gives defendants a cheaper district-court non-infringement argument than an invalidity fight.

Because the '790 was not PTAB-tested, there is no estoppel, no institution decision, and no Federal Circuit validity ruling shaping this case. Conversely — and this matters for anyone valuing the family — the '790's validity has never been adversarially tested anywhere, and the 52+ assertions all resolved by settlement or dismissal rather than by judgment.

**Caveat

Counsel of record — Cedar Lane Techs. Inc. v. TCL Communication, Inc., No. 1:20-cv-00836-CFC (D. Del.)

Bottom line: Two lawyers appear in the plaintiff-side filings for this Delaware case. Raeann Warner of Jacobs & Crumplar, P.A. in Wilmington is the confirmed Delaware counsel of record—she filed the complaint, the Rule 7.1 disclosure, the service/waiver papers, and the extension motion. Isaac Rabicoff of Rabicoff Law LLC is the Cedar Lane campaign’s lead/coordinating patent counsel and is identified as plaintiff’s counsel in the contemporaneous Cedar Lane Delaware pleadings, but the publicly available docket excerpt for this TCL case does not reflect a pro hac vice motion or appearance order for him. I did not find any sealed counsel list or in-house appearance.

Docket support

• Complaint filed June 22, 2020 against TCL Communication, Inc., asserting, inter alia, U.S. Patent No. 6,972,790; filing attorney shown as Raeann Warner — D.I. 1, No. 1:20-cv-00836-CFC (D. Del.); see Justia docket, https://dockets.justia.com/docket/delaware/dedce/1:2020cv00836/72499.
• Rule 7.1 disclosure statement filed June 22, 2020 — D.I. 4 (Warner).
• Return of service (served June 24, 2020) — D.I. 6; waiver of service — D.I. 7; consent motion for extension of TCL’s answer deadline to October 13, 2020 — D.I. 8 (all filed by Warner).
• The case was assigned to Judge Colm F. Connolly on June 24, 2020.
• Patent report lists 6,473,527; 6,516,147; 6,566,805; 6,972,774; and 6,972,790 — D.I. 3.

Caveats

• Rabicoff’s formal status in this specific case: In other Cedar Lane Delaware complaints filed at the same time, the signature block lists both Warner and Rabicoff, with Rabicoff shown as “Pro Hac Vice admission pending.” See, e.g., Cedar Lane v. LiveXLive Media, No. 1:20-cv-01370 (D. Del.), Rule 7.1 disclosure dated Oct. 9, 2020. I could not confirm from the public docket that a PHV motion was actually filed or granted in the TCL case before the pleadings-stage period ended. If the question is strictly “whose appearance is entered,” the answer is Raeann Warner.
• No in-house counsel of record: Cedar Lane’s founder/director Greg Benoit is a lawyer and is identified in corporate filings as Cedar Lane’s authorized person, but he did not enter an appearance in this case. No Cedar Lane in-house attorney appears on the docket.
• No sealed filings identified in the publicly available docket excerpt for the relevant period.

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

Let me pull the full docket and look for defense-side appearances.

Bottom line

I could not verify any attorney of record for TCL Communication, Inc. in Cedar Lane Technologies Inc. v. TCL Communication, Inc., No. 1:20-cv-00836-CFC (D. Del.). Every publicly indexed version of the docket I could reach stops before any defense appearance was entered. I will not name attorneys I cannot source, so the honest answer is: as of the last publicly available docket state, no counsel had appeared for TCL in this action.

What the docket actually shows

The case was filed June 22, 2020 in the District of Delaware before Judge Colm F. Connolly, asserting U.S. Patents 6,473,527; 6,516,147; 6,566,805; 6,972,774; and 6,972,790 (the '790 patent being the one in our case metadata). Docket activity, per Justia, UniCourt, and CourtListener RECAP mirrors:

Sources: https://dockets.justia.com/docket/delaware/dedce/1:2020cv00836/72499 and https://unicourt.com/case/pc-db5-cedar-lane-technologies-inc-v-tcl-communication-inc-552896 (last synced from PACER 8/21/2020).

The critical detail: D.I. 7 (waiver of service) and D.I. 8 (consent extension) were both filed by plaintiff's counsel. A consent motion requires the defendant's agreement, but it does not put an attorney on the record, and no Rule 83.5 / Local Rule 83.5(b) entry of appearance, no corporate disclosure statement from TCL, and no answer or motion to dismiss appears in the docket text available through the August 2020 sync.

Why the record is thin

• Pleadings-stage case with no contested motion practice. RPX's October 26, 2020 campaign roundup expressly describes the TCL Communication case as one of the Cedar Lane matters that "remain in the pleadings stage," alongside Arrow Electronics and WPG Americas — i.e., no litigation activity generating opinions or press coverage naming defense counsel. https://www.mondaq.com/unitedstates/patent/[998106](/patent/998106)
• Cases in this campaign settled rather than litigated. Roughly 80% of Cedar Lane's suits resolved by settlement within ~90 days; most never produced a single substantive order. Cedar Lane also routinely dismissed before appearance.
• CourtListener's RECAP copy of the Delaware docket does not have defense-side entries, and the case is reported as closed by at least one litigation-data aggregator (ai-lab-cl-prod.azurewebsites.net case page for 1:20-cv-00836 lists status "Closed"), consistent with a voluntary dismissal. I could not retrieve the specific dismissal docket entry number or date.

What I can verify about TCL's counsel, with appropriate caveats

• Unverified lead, not counsel of record here: In TCL Communication Technology Holdings, Ltd. v. Telefonaktiebolaget LM Ericsson, No. SACV 14-00341-JVS (C.D. Cal.), TCL was represented by Sheppard, Mullin, Richter & Hampton LLP (e.g., Matthew W. Holder), per the joint pretrial filings in that case (D.I. 1313, filed 1/10/2017). That is a different case, a different TCL entity, four years earlier — it does not establish an appearance in 1:20-cv-00836, and I am flagging it only as a research lead if you want to check whether the same firm was retained for the Cedar Lane matter.
• A second, related suit: Cedar Lane Technologies Inc. v. TCL Corporation, No. 6:21-cv-00408 (W.D. Tex., Judge Alan D. Albright), filed April 26, 2021. TCL never appeared there either; Cedar Lane filed a notice of voluntary dismissal on May 28, 2021 (D.I. 8). Documents: https://services.patexia.com/lawsuits/Cedar-Lane-Technologies-Inc-v-TCL-Corporation-id-[152035](/patent/152035)/documents

Recommended verification steps

Since the free mirrors are stale, counsel of record can only be confirmed from primary sources:

1. PACER — D. Del. CM/ECF, 1:20-cv-00836-CFC. Pull the full docket (or the "Attorneys" / party-attributes tab). Any defense appearance would appear as a "NOTICE of Appearance" or "MOTION for Pro Hac Vice Admission" in the D.I. 9–20 range, roughly October 2020 through early 2021, given the 10/13/2020 answer deadline.
2. Check the dismissal entry. If the case was dismissed on a stipulation of dismissal, the stipulation is typically signed by defense counsel and will name the firm and attorney directly — this is usually the fastest route in a settled NPE case.
3. Check for a pro hac vice motion's accompanying certificates, which list both the local Delaware counsel and the out-of-state lead counsel with firm addresses.

If you can pull the post-August-2020 docket sheet or the dismissal stipulation, I can identify and profile each attorney with firm, office, and litigation history. I would rather leave this blank than supply a name the record does not support.
