Cedar Lane Technologies Inc. v. TCL Communication, Inc.

I'll research this case across docket, PTAB, and trade-press sources before drafting.

Now let me pull the docket history, patent subject matter, and Cedar Lane's litigation profile.

Let me pin down the case outcome and the remaining patent titles.

Case Overview

Parties and posture. Cedar Lane Technologies Inc. is a patent-holding plaintiff that does not make or sell products; foreign IP-dispute databases (Korea's KOTRA trade database) expressly tag it "NPE," and its Rule 7.1 disclosure in this case listed "No Parents or Affiliates Listed" (D.I. 4). It acquired the asserted family on the secondary market — public reporting indicates Cedar Lane was assigned the '527 and '790 patents in May 2019, and then filed 38 complaints asserting the '527 patent and 46 asserting the '790 patent (The Recycler, reporting on the Cedar Lane v. Pantum suit, therecycler.com). Defendant TCL Communication, Inc. is the U.S. mobile-device arm of China's TCL group, selling TCL- and Alcatel-branded handsets and tablets. Cedar Lane filed the complaint on June 22, 2020 in the U.S. District Court for the District of Delaware, Wilmington Division, assigned to Judge Colm F. Connolly (case suffix -CFC) (dockets.justia.com; unicourt). Plaintiff's Delaware counsel of record was Raeann Warner (D.I. 1); the docket shows service on TCL on 6/24/2020 (D.I. 6), a waiver of service sent 7/14/2020 (D.I. 7), and a consent extension pushing TCL's response to October 13, 2020, so-ordered by Judge Connolly on 7/16/2020 (D.I. 8).

The accused technology and the five patents. The complaint pleads infringement under 35 U.S.C. § 271 with a jury demand, attaching 27 exhibits — notably grouped claim charts designated 9a–9c, 11a–11c, 13a–13c, 14a–14c, 15a–15b, and 16a–16c, i.e., three chart sets per patent family, consistent with a multi-model smartphone/tablet accusation (D.I. 1). KOTRA's dispute record classifies the technology as "Information & Communications → AV (Audio-Video)" and lists the same five patents (KOTRA). The patents, per the AO-120 report at D.I. 3, are US 6,473,527; 6,516,147; 6,566,805; 6,972,774; and 6,972,790. Only the '527 has a publicly verified title: "Module and method for interfacing analog/digital converting means and JPEG compression means" — a hardware-interface patent on buffering digitized image lines from an A/D converter and feeding them block-wise into a JPEG compressor's built-in memory, thereby eliminating a discrete external RAM in cameras and scanners (see the claim-level analysis of the '527 in Cedar Lane's later complaints, exparte.ai). The '527 uses § 112(f) means-plus-function language ("read control means," "memory means," "output control means"), which is where the infringement fight would have centered. Caveat: I could not verify the titles, claim text, or per-patent technical content of the '147, '805, '774, and '790 from any of the sources I reviewed (the complaint's chart exhibits are not publicly readable in the free dockets). They issue from the same mid-1990s/early-2000s digital-image-acquisition lineage as the '527 and were consistently asserted together with the '527 and '790 in Cedar Lane's imaging campaign against camera-, scanner-, and DVR-equipped devices, but any one-line sketch of those four would be inference rather than sourced fact. Likewise, the specific accused TCL/Alcatel model numbers appear only in the exhibit charts, which I could not open; the accusation is best characterized as TCL's camera-equipped handsets and tablets and their on-device JPEG image pipelines.

Why this case matters — and how it ended. Venue is the story: Delaware in 2020 was the default PAE forum, offering a fast, patent-savvy bench and — critically — a defendant, TCL Communication, Inc., with U.S. operations and a Delaware-registered presence, making jurisdiction and venue uncontestable even under TC Heartland. Judge Connolly's courtroom became, starting in 2022, the most aggressive in the country on third-party litigation-funding disclosure, which makes early-CFC-era NPE dockets like this one a useful baseline for that later transparency push. On the merits, the case is a textbook high-volume assertion pattern rather than a litigated dispute: Cedar Lane filed this suit in a rolling multi-district wave (D. Del., W.D. Tex., S.D. Tex., S.D.N.Y., D.N.J. — dozens of defendants, repeatedly dismissing voluntarily within months, e.g., Castle Global (D. Del. 1:20-cv-00570, dismissed 8/31/2020), Caterpillar (S.D. Tex. 4:20-cv-02169, dismissed 7/20/2020), and Panasonic i-PRO (S.D. Tex. 4:20-cv-01392, dismissed on settlement 8/17/2020)). This case follows that arc: the docket I could retrieve terminates in the summer of 2020, no claim construction opinion, summary judgment ruling, trial, or Federal Circuit appeal exists for it, and a third-party litigation database lists the matter as "Closed" (exparte.ai) — but I could not retrieve the actual dismissal entry or settlement papers from PACER, so the precise termination date and terms are unverified. What is verified is that Cedar Lane re-sued the parent, TCL Corporation, in W.D. Tex. before Judge Alan D. Albright (6:21-cv-00408) on April 26, 2021, and voluntarily dismissed that case on May 28, 2021 (Patexia) — the classic re-file-and-dismiss churn used to reset negotiating leverage. On PTAB linkage: Cedar Lane's portfolio was targeted by Unified Patents, which filed IPR2020-00006 against Cedar Lane's US 7,173,177, instituted 3/18/2020 (RPX) — but that patent is not among the five asserted here, and I found no IPR petition against the '527, '147, '805, '774, or '790 tied to this case. That absence is itself notable: the '527's means-plus-function claim structure made it vulnerable to § 112 and prior-art attack, yet the case resolved (apparently) before any validity challenge was joined, which is exactly the economic logic of the PAE model — quick, low-value settlements in volume, with no precedent generated.

I'll research this case systematically, starting with the docket and early filings.

Bottom line up front

This is a short-lived NPE campaign case, not a litigated merits case. Cedar Lane filed a five-patent complaint against TCL Communication in D. Del. on 2020-06-22, obtained an extension of TCL's answer deadline to 2020-10-13, and — on every public record I can retrieve — the case generated no Markman order, no summary-judgment opinion, no trial, no verdict, and no appellate decision. Docket aggregators now list the case as closed. I was unable to verify the precise terminating docket entry and date (see "Evidentiary gaps" below); everything else in this memo is sourced.

Verified chronology

Note on the absence of an answer/counterclaim record: Because the only substantive deadline reset was to 2020-10-13, and no answer, motion to dismiss, motion to transfer, or motion to stay appears in any public index, the most probable resolution is an early consensual termination (voluntary dismissal, likely without prejudice, coincident with a license/settlement) rather than an adjudication. That inference is consistent with Cedar Lane's documented campaign behavior (below), but it is an inference — I did not retrieve the dismissal notice or order itself.

Why there is essentially no motion practice to report

Cedar Lane Technologies (founded 2019 in British Columbia by Greg Benoit; portfolio acquired largely from Intellectual Ventures) is the archetypal high-volume, fast-settlement NPE:

• Lex Machina's 2022 patent-litigation report ranked Cedar Lane the #1 plaintiff by number of patent suits filed in 2021; Chinese IP-protection bulletins tracking the campaign put the total at 270 suits (mid-2022) rising to ~325 — against Huawei, Xiaomi, TCL, Apple, MediaTek, Disney, Comcast, LG, and dozens of others.
• Reported resolution statistics: ~80% settled, median case life ~77–90 days — i.e., the campaign is structurally designed to end before Markman. (gdoip.com analysis, 2022-07-04; Shenzhen IP Protection Center warning, 2023-02-16, both citing Lex Machina.)
• Cedar Lane's suits were usually filed with local Delaware counsel (Warner/Bayard, P.A.) plus Rabicoff Law LLC as lead; Rabicoff handled roughly 58 of the campaign's cases.

None of this is a substitute for the docket, but it explains the total absence of the pre-trial, Markman, trial, and post-trial events your outline asks about: those stages were never reached.

Follow-on TCL litigation (the only TCL-specific development that is fully documented)

Cedar Lane re-filed against the parent entity rather than the U.S. operating subsidiary:

• 2021-04-26: Cedar Lane Technologies Inc. v. TCL Corporation, W.D. Tex. No. 6:21-cv-00408, assigned to Judge Alan D. Albright (Isaac Rabicoff appearing; Rule 7 disclosure; AO-120 filed).
• 2021-05-07: TCL Corporation served (answer due 2021-05-28).
• 2021-05-28: D.I. 8 Notice of Voluntary Dismissal by Cedar Lane; PTO report sent 2021-06-01. (Patexia docket)

This ~32-day file-to-dismissal cycle is the campaign's signature and is strong circumstantial evidence that the D. Del. case also ended by voluntary dismissal/settlement.

One metadata caveat worth flagging: the Korean KOTRA overseas-IP dispute database entry for 1:20-cv-00836 lists eight patents (adding US 7,292,261, 8,165,867, 8,537,242) — inconsistent with the court's own AO-120 in D.I. 3, which lists five. The authoritative case metadata (five patents) controls for this case; the extra three likely reflect a different Cedar Lane–TCL filing or aggregator bleed-through. (KOTRA record)

Parallel PTAB activity

There is no IPR/PGR on the five patents in this case attributable to TCL that I could locate. What exists in the record is third-party (Unified Patents) and portfolio-wide:

• October 2019: Unified Patents filed an IPR against a Cedar Lane patent and prevailed — the only Cedar Lane patent invalidated through PTAB as of 2022 reporting. (gdoip.com, 2022-07-04) — I could not confirm the IPR number or confirm whether the target was one of the five patents here; Cedar Lane's most-asserted patents have been 6,972,790 ("Host interface for imaging arrays," asserted in ~167 cases) and 8,537,242, which makes the '790 a plausible but unverified target. Treat the patent identity as an open question requiring PTAB docket confirmation.
• 2021-04-20: Unified ran a PATROLL prior-art crowdsourcing contest on U.S. 8,165,867 (a Cedar Lane patent asserted against TCL Communication, D-Link, Disney, Dish, Comcast, LG, iHeartMedia, ViacomCBS, SiriusXM) — a $3,000 award, indicating pre-IPR scouting rather than a filed petition against the patents-in-suit here.

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

Let me pull the CourtListener docket and parties pages for this case.

Bottom line

I could not verify any counsel of record for TCL Communication, Inc. in D. Del. No. 1:20-cv-00836 from the sources I was able to reach. Per the operating rule against inventing attorneys, I am not going to name anyone as TCL's counsel without a docket-sourced basis. Here is exactly what the record I could access shows, and why the gap exists.

What the accessible docket shows (through mid‑2020)

The free docket mirrors (Justia, UniCourt, CourtListener's "Plaintiff(s) v. Defendant(s)" miscellaneous docket where the complaint was originally e-filed) capture this case only up to roughly August 21, 2020, and contain no defense-side appearance, answer, or motion:

Sources: https://dockets.justia.com/docket/delaware/dedce/1:2020cv00836/72499; https://unicourt.com/case/pc-db5-cedar-lane-technologies-inc-v-tcl-communication-inc-[552896](/patent/552896)

Reasons the defense roster is not verifiable from public/free sources

1. Free mirrors are stale. Justia's docket page explicitly states "This docket was last retrieved on June 22, 2020"; UniCourt's last update is 08/21/2020. Any D.I. 9+ (appearance, motion to dismiss, stay, or stipulation of dismissal) is behind PACER/CM‑ECF and was not captured.
2. The case appears to be closed. A third-party litigation database indexes 1:20-cv-00836‑CFC with status "Closed" (https://ai-lab-cl-prod.azurewebsites.net/case/dct/ded/1:20-cv-00836/cedar-lane-tech-inc-v-tcl-communication-inc), and the case number appears as a closed "related case" in later Cedar Lane Delaware filings (e.g., 1:23-cv-00376‑RGA per lexdana.ai/lawsuits/188123). Cedar Lane's campaign was overwhelmingly resolved by voluntary dismissal/settlement rather than litigated judgment (see Mondaq/Unified Patents reporting on the campaign: https://www.mondaq.com/unitedstates/patent/[998106](/patent/998106)). It is entirely plausible — though I cannot confirm it — that TCL was dismissed before ever filing an appearance, which would mean there is no counsel of record for TCL at all.
3. No opinion, Law360, or Reuters piece tying this docket to a defense firm surfaced. Unlike Cedar Lane's cases that produced substantive rulings (e.g., the N.D. Cal. Blackmagic Design matter and the show-cause order reported at the Mondaq link above), this Delaware TCL docket produced no indexed decision.

What I deliberately did not do

• I did not import counsel from the earlier TCL matters I saw in search results. In Godo Kaisha IP Bridge 1 v. TCL Communication Technology Holdings Ltd., D. Del. 1:15-cv-00634, the Ropes & Gray / Young Conaway Stargatt & Taylor names that appear (James R. Batchelder, Andrew T. Radsch, Rebecca R. Carrizosa, Steven Pepe, Kevin J. Post, Alexander E. Middleton, Elena C. Norman, Anne Shea Gaza, Samantha G. Wilson) are captioned as "Attorneys for Plaintiff" — not for TCL. Likewise, the Ropes & Gray/TCL names in IPR2021-00906 (Cradlepoint et al.) are a different proceeding and do not establish an appearance in 1:20-cv-00836.
• I did not treat the D.I. 8 consent motion as a defense filing; it was docketed by plaintiff's counsel.

Plaintiff's counsel (for contrast, confirmed)

• Raeann Warner — Bayard, P.A., Wilmington, DE — lead/filing attorney for Cedar Lane (signature on D.I. 1, 4, 8); a frequent Delaware local counsel in Cedar Lane's NPE campaign (also appears in 1:20-cv-00634, Cedar Lane v. Enplug).

How to close the gap (recommended verification path)

1. Pull the full PACER docket for 1:20-cv-00836-CFC (post-August 2020 entries) — look for a Notice of Appearance, Rule 7.1 disclosure, motion to dismiss, and the dismissal order. A RECAP/CourtListener "Parties" page for this docket ID would show "Represented by" blocks if any attorney appeared.
2. If entries show a stipulation/notice of voluntary dismissal with defense signatures, the signature block will name defense counsel and firm.
3. If the docket instead shows dismissal before any appearance, the correct answer is: no counsel of record for TCL existed — the case ended without an appearance.

Confidence statement: High confidence on the docket contents through 07/16/2020 (multiple independent mirrors agree). Zero verified basis for naming any TCL attorney; treat any name you see elsewhere as unconfirmed until checked against the PACER docket for this specific case number.
