Cedar Lane Technologies Inc. v. Lenovo Inc.

I'll research this case before drafting. Let me start with several parallel searches.

Good initial picture. Now let me dig into the '242 patent's prosecution/assignment history, PTAB challenges, the earlier W.D. Tex. Lenovo suit, and Cedar Lane's campaign data.

Case Overview: Cedar Lane Technologies Inc. v. Lenovo (United States) Inc., No. 1:22-cv-00051-RGA (D. Del.)

The parties. Cedar Lane Technologies Inc. is a Canadian patent-assertion entity (NPE/PAE) — a British Columbia corporation with a listed principal place of business at 560 Baker Street, Suite 1, Nelson, BC, formed on April 29, 2019, with attorney Greg Benoit as director (RPX, "In a Matter of Months, Former IV Portfolio Bounces Off One NPE to Land in New Cedar Lane Complaints," Nov. 9, 2019; Cedar Lane complaint, Cedar Lane v. Alps Alpine N.A., W.D. Wash. No. 2:23-cv-00001). It does not make or sell products; Stanford's NPE Litigation Database classifies it as an "acquired patents" asserter (Stanford NPE DB), and RPX reported that its portfolio was assembled largely from former Intellectual Ventures assets routed through AVInnov LLC. Per IAM, Cedar Lane was the single most prolific patent plaintiff in the U.S. in 2022 and reported a roughly 96% settlement rate among terminated cases (IAM, "Examining the practice of Cedar Lane Technologies – America's top-filing NPE," Mar. 20, 2023 — headline/summary available at IAM). The defendant named on the docket is Lenovo (United States) Inc., the U.S. subsidiary of Chinese technology manufacturer Lenovo Group Limited (the case caption in our metadata uses "Lenovo Inc."; the docket and every filing use "Lenovo (United States), Inc."). Lenovo is an operating company — PCs, tablets, smartphones, servers and peripherals.

The technology and the asserted patent. Our case metadata identifies U.S. Patent No. 8,537,242, "Host interface for imaging arrays" as the patent at issue, and that is the right focal point: the '242 (issued Sept. 17, 2013; application filed Oct. 27, 2005 as a divisional; earliest priority Jan. 21, 2000; named inventor Mark Suska; prosecution counsel McAndrews Held & Malloy) claims the interface between a CMOS/CCD image sensor and a host processor. In one line: a method of receiving image data from an imaging array, buffering it in a FIFO, incrementing a FIFO counter, comparing the count to a FIFO limit, and generating an interrupt to the processor when the threshold is met so the data can be transferred — i.e., the high-water-mark/flow-control logic that lets a sensor stream data asynchronously to a microprocessor (see the patent abstract and claim-1 analysis reproduced in Patsnap's litigation record for the '242 and the Ex Parte complaint analysis of the parallel W.D. Wash. case). The claim is drafted at a level of generality that reads on essentially any device pairing an image sensor with a processor, which is why Cedar Lane asserted this family against webcams, security cameras, drones, printers, phones, tablets and even rental-car telematics. Importantly, the complaint in this case did not assert the '242 alone — the D. Del. filing on Jan. 13, 2022 named nine patents: 10,346,105; 6,473,527; 6,516,147; 6,566,805; 6,972,774; 6,972,790; 7,292,261; 8,165,867; and 8,537,242 (KOTRA IP dispute record, citing Korean IP Protection Agency). The accused instrumentalities were Lenovo's smartphone and tablet lines — although I flag that this product identification comes from a Chinese-language industry newsletter (IP Weekly), not from a source I could confirm against the complaint's Exhibit claim charts.

Procedural posture and venue. Filed January 13, 2022 in the District of Delaware and assigned on January 19, 2022 to Judge Richard G. Andrews, as one of four related complaints filed the same day (Nos. 1:22-cv-00050, -051, -054, -058) (DocketBird docket sheet). Lenovo was served January 20, 2022; the parties twice stipulated to extend the response deadline, first to March 28 and then to April 27, 2022. The case never reached the merits: on April 21, 2022 — six days before the extended answer deadline — Cedar Lane filed a Notice of Voluntary Dismissal, which Judge Andrews so-ordered the same day, terminating the case roughly 98 days after filing. There is no answer, no motion to dismiss, no scheduling order, no claim construction, and no substantive ruling. Because no answer or summary-judgment motion had been served, a unilateral Rule 41(a)(1)(A)(i) notice would operate without prejudice — but note the docket shows no stipulated dismissal or license document, so the settlement terms are not public and I cannot confirm whether a license was taken. Delaware mattered here for the usual reasons: it is Cedar Lane's preferred East Coast venue (local counsel David

I'll research this case systematically across dockets, PTAB, and legal press.

Initial docket shows a 2022-04-21 voluntary dismissal — but the asserted patent in the metadata is the '242, so I need to check whether a later Lenovo case carried that patent and look for PTAB activity.

The Delaware case appears to have closed quickly. I need to confirm the dismissal terms and check for PTAB challenges to the '242 and any follow-on Lenovo suit.

Bottom line

This case never became a real litigation. Cedar Lane filed a nine-patent, 18-exhibit complaint against Lenovo (United States) Inc. in D. Del. on 2022-01-13; Lenovo was served on 2022-01-20; Lenovo obtained two answer extensions and never filed an answer, counterclaim, or motion; and Cedar Lane voluntarily dismissed the case on 2022-04-21 — 98 days after filing and six days before Lenovo's extended response deadline. There was no Rule 12 motion, no transfer or stay motion, no Markman, no discovery, no IPR, no trial, no judgment, and no appeal. The case is closed; the only public "outcome" is a plaintiff-side voluntary dismissal, which (for the reasons below) the docket indicates was without prejudice.

Chronology

That is the entire docket: ten entries, no substantive motion practice.

Analysis by category requested

1. Pleadings. Complaint only. No answer, no affirmative defenses, no counterclaims (no declaratory-judgment counterclaims of non-infringance/invalidity were ever pleaded by Lenovo). The complaint was filed together with 18 exhibits — i.e., element-by-element claim charts across a large patent set — and an AO 120 report naming U.S. Patent Nos. 10,346,105; 6,473,527; 6,516,147; 6,566,805; 6,972,774 (the captured docket text truncates the list). The Korean government IP-dispute database (KOTRA), reporting on this exact case number, lists nine asserted patents: 10,346,105; 6,473,527; 6,516,147; 6,566,805; 6,972,774; 6,972,790; 7,292,261; 8,165,867; and 8,537,242 (KOTRA record). Caveat: I could not retrieve the full AO 120 or the complaint text itself, so the '242's inclusion rests on the KOTRA record plus the case metadata you supplied — not on a first-hand read of D.I. 1. Flag for verification.

2. Pre-trial motions of substance. None. No motion to dismiss, no § 1404(a) transfer motion (notable, since Lenovo (US) is a N.D. Cal./Morrisville, NC-anchored entity and D. Del. posture was purely plaintiff's choice), no motion to stay pending IPR, no summary-judgment motion, no Rule 12(c) motion. The only filings after service were the two stipulated extensions (D.I. 6, 8).

3. Claim construction / Markman. Did not occur. No scheduling order, no § 282 disclosures, no Joint Claim Construction Statement. The case terminated roughly three months before any Markman track would have begun.

4. Discovery milestones. None of strategic significance — no Rule 26(f) conference, no ESI order, no infringement/invalidity contentions, no depositions, no expert reports.

5. Trial, verdict, post-trial motions. None. No trial setting, no verdict, no JMOL/Rule 59 motion, no § 285 fee motion.

6. Final disposition / present posture. Closed — voluntary dismissal, 2022-04-21, with the Court's order terminating the case. Key point on prejudice: the docket text for D.I. 10 reads simply "Granting [9] Notice of Voluntary Dismissal" and — unlike contemporaneous orders in the companion cases (Snap, D.I. 7: "Voluntary Dismissal With Prejudice," 2022-01-25; Epix, D.I. 13: "Stipulation of Dismissal With Prejudice," 2022-03-16) — contains no "with prejudice" language. Combined with the fact that Lenovo had not yet answered, Cedar Lane was in a position to dismiss as of right, without prejudice, under Fed. R. Civ. P. 41(a)(1)(A)(i). My assessment: the Lenovo dismissal was without prejudice, leaving Cedar Lane free to re-assert (the '242 has a long assertion history against dozens of other defendants, e.g., Avis, Voxx, Magic Leap, Yi, Video Network Security, Qualcomm). No settlement agreement, consent judgment, license, or Rule 41(a)(1)(A)(ii) joint stipulation appears on the docket. No appeal (and none available — a plaintiff-side voluntary dismissal is not a reviewable adverse judgment).

7. Parallel PTAB proceedings. I found no IPR or PGR on U.S. Pat. No. 8,537,242 — no Lenovo-filed petition and no third-party petition — in my searches of PTAB materials. Given the case's three-month lifespan, no IPR could realistically have been filed, instituted, or used as a stay vehicle here. This is a negative finding, not a confirmed absence; it should be verified directly against the PTAB Patent Trial and Appeal Board Endpoint / PTAB docket and USPTO Patent Center for the '242. (Note: Cedar Lane's wider portfolio has drawn PTAB challenges in other matters, but I could not source any '242 proceeding and will not assert one.)

Strategic read

• This was a volume-licensing campaign, not a merits case. Cedar Lane (a Canadian NPE; plaintiff-side counsel of record in D. Del. was David W. deBruin, with Isaac Rabicoff/Rabicoff Law and later Napoli Shkolnik running parallel W.D. Tex. and D.N.J. filings) opened 2021–2023 with dozens of near-identical complaints, then dismissed the overwhelming majority within weeks to months. Lenovo fits that pattern precisely: two extension stipulations, then a walk-away before any responsive pleading.
• Defendant's leverage was procedural, not adjudicative. By stalling past the answer deadline via stipulation while evaluating the claim charts, Lenovo preserved full Rule 12(b)(6) and IPR options and never had to commit to a defense — a posture that makes an early, cheap exit rational for the plaintiff too. No public record shows whether money or a license changed hands.
• Entity note: the named defendant is the U.S. subsidiary, Lenovo (United States) Inc. (the prompt caption's "Lenovo Inc." is a shorthand); **Len

Let me pull the actual docket page and complaint signature block for this case.

Counsel of Record for Plaintiff Cedar Lane Technologies Inc.

Cedar Lane Technologies Inc. v. Lenovo (United States) Inc., No. 1:22-cv-00051-RGA (D. Del.) — assigned to Judge Richard G. Andrews; § 271 patent case filed 1/13/2022 over U.S. Patent Nos. 10,346,105; 6,473,527; 6,516,147; 6,566,805; 6,972,774; 6,972,790; 7,292,261; 8,165,867; and 8,537,242 (the '242 being the patent carried in the case metadata).

What the docket actually shows

• D.I. 1 (Jan. 13, 2022) — Complaint for patent infringement with jury demand, filed by Cedar Lane; the CM/ECF filing-user attribution is "(deBruin, David)", and the same-day D.I. 4 Rule 7.1 disclosure statement ("No Parents or Affiliates Listed") was filed for Cedar Lane through the same counsel. (Docket text as mirrored on CourtListener/Patexia/DocketBird; receipt no. ADEDC-3781038.)
• D.I. 7 (Jan. 26, 2022) — Summons returned executed; Lenovo (United States) Inc. served 1/20/2022.
• D.I. 6, 8 (Jan. 24 & Mar. 14, 2022) — Stipulated extensions of Lenovo's response deadline (to 3/28/2022, then 4/27/2022), both entered by Judge Andrews. Notably, these stipulations were filed by Lenovo's counsel, not by Cedar Lane.
• D.I. 9–10 (Apr. 21, 2022) — Cedar Lane's Notice of Voluntary Dismissal as to Lenovo (United States), Inc., so ordered the same day; case terminated. Patent/Trademark report updated to list only 10,346,105; 6,473,527; 6,516,147; 6,566,805; 6,972,774.
• Total docket: 10 entries. There is no motion for pro hac vice admission, no entry of appearance, and no notice of change of counsel for Cedar Lane anywhere in this file.

Explicit gaps / caveats

• No non-Delaware (e.g., Texas-based) co-counsel appears in this case. Because Lenovo had not yet answered and no scheduling order issued before the April 21, 2022 dismissal, Cedar Lane never needed to move out-of-state trial counsel into the case pro hac vice — so any "national" or "lead trial counsel" who may have worked behind the scenes on the '242 campaign (Cedar Lane filed heavily in W.D. Tex., including Cedar Lane v. Lenovo Group Ltd., No. 6:21-cv-00021 (W.D. Tex.)) is not of record here and I will not name one without a docket entry. The complaint signature block itself was not retrievable in this session (CourtListener/Justia PDF link not accessible); the filer attribution plus contemporaneous reporting (LawStreet Media: "Cedar Lane Technologies is represented by Gawthrop Greenwood PC") supports deBruin as the sole counsel of record.
• No in-house counsel for Cedar Lane (an NPE with no parent/affiliates disclosed under Rule 7.1) appears on the docket.
• Nothing in this file is sealed; the absence of additional appearances reflects the case's early voluntary dismissal, not sealing.
• For comparison on Cedar Lane's later Delaware filings (2023–2026, e.g., Cedar Lane v. TVL International, 1:23-cv-00376-RGA; Cedar Lane v. Speechify, 1:2026-cv-00031; Cedar Lane v. BTG Pactual, 1:26-cv-01178), the Delaware counsel of record shifted to Brian E. Lutness (Silverman, McDonald & Friedman, Wilmington) — indicating a change of Delaware counsel after this 2022 case, not during it.

Bottom line: for case No. 1:22-cv-00051-RGA, the sole plaintiff-side counsel of record is David W. deBruin of Gawthrop Greenwood, PC (Wilmington, Delaware), serving as lead and local counsel; no pro hac vice counsel or in-house attorney ever appeared before the case was voluntarily dismissed on April 21, 2022.

I'll research the docket and counsel of record for Lenovo in this case.

Key finding so far: the case was voluntarily dismissed in April 2022 after only two extension stipulations. Let me identify who filed those.

The docket text I've found doesn't yet show the filing attorney for D.I. 6/8. Let me dig for that attribution and Lenovo's Delaware counsel in this period.

Bottom line first

There is very little "counsel of record" to report in this case, because Lenovo never appeared in substance. The case was filed 1/13/2022 and Cedar Lane voluntarily dismissed it on 4/21/2022 — before any answer, motion to dismiss, notice of appearance, or pro hac vice motion was filed by the defense. The only two defense-side filings on the docket are extension stipulations. Critically, the free docket text available for those two entries does not carry the filer/signature attribution, so I cannot confirm from a primary source who signed them. Below I separate what is documented from what is a well-supported inference.

Docket facts (documented)

Sources: DocketBird docket sheet, https://www.docketbird.com/court-cases/Cedar-Lane-Technologies-Inc-v-Lenovo-United-States-Inc/ded-1:2022-cv-00051 ; Patexia docket (documents tab), https://services.patexia.com/lawsuits/Cedar-Lane-Technologies-Inc-v-Lenovo--United-States--Inc-id-[160591](/patent/160591)/documents

Note two caption corrections to the case metadata: the actual named defendant was Lenovo (United States) Inc. (not "Lenovo Inc."), and the complaint asserted nine patents (10,346,105; 6,473,527; 6,516,147; 6,566,805; 6,972,774; 6,972,790; 7,292,261; 8,165,867; and 8,537,242), per the Korean IPO case record and the Rule 3 report at D.I. 3. There is also a separate, earlier Cedar Lane suit against the parent, Cedar Lane Techs. v. Lenovo Group Ltd., No. 6:21-cv-00021 (W.D. Tex.).

Counsel identification

Confirmed by primary record in this case: none. No notice of appearance, no pro hac vice motion, no Rule 7.1 disclosure, and no answer was ever filed by Lenovo in 1:22-cv-00051, so no attorney's name appears in the case record I could verify. The signature blocks of D.I. 6 and D.I. 8 are only visible in the PDFs on PACER/CM-ECF; the free aggregator docket text omits the "(Smith, Rodger)"-style filer tag that D. Del. dockets normally carry. This is exactly the kind of gap I won't paper over.

Best-supported inference (not confirmed):

Evidence for the Morris Nichols Lenovo relationship: signature blocks in LiTL LLC v. Lenovo (United States), Inc., D. Del. No. 1:20-cv-00689 (filed Feb. 3, 2023), https://www.docketalarm.com/cases/PTAB/IPR2024-00457/MICROSOFT_CORPORATION/docs/01-30-2024-Petitioner/Exhibit-1025-1025___Stipulation_of_Dismissal,_LiTL_LLC_v_Lenovo_United_States_Inc,_N.pdf ; InterDigital Tech. Corp. v. Lenovo Holding Co., D. Del. No. 1:19-cv-01590, D.I. 235 (9/23/2022), https://www.archive.org/download/gov.uscourts.ded.69848/gov.uscourts.ded.69848.235.0.pdf ; Lenovo v. InterDigital, No. 1:20-cv-00493, D.I. 39 (PHV motion for Sidley's Richard A. Cederoth, signed by Blumenfeld/Smith/Clark), https://www.docketalarm.com/cases/Delaware_District_Court/1--20-cv-00493/Lenovo_%28United_States%29_Inc._et_al_v._InterDigital_Technology_Corporation_et_al/docs/39.pdf ; and the Digital Cache docket, https://dockets.justia.com/docket/delaware/dedce/1:2022cv00225/78096 (Rodger Smith filing for Lenovo before Judge Andrews in March 2022).

Caveats on that inference: (1) The Digital Cache and LiTL appearances are probative but not dispositive — Lenovo used different local firms in different matters in 2022 (e.g., Kelly Lynne Freund and Michelle Morgan appeared for Lenovo in Genesis FS Card Services v. Lenovo (United States) Inc., No. 1:22-cv-01385 (D. Del.), on 11/14/2022, https://dockets.justia.com/docket/delaware/dedce/1:2022cv01385/80474 — I could not verify their firm). (2) No pro hac vice admission appears in this case, so no national/lead trial counsel — e.g., Sidley Austin's Richard A. Cederoth, who was Lenovo's outside PHV counsel in Lenovo v. InterDigital — is of record here. (3) Lenovo also used PHV counsel in LiTL (Martin R. Bader, Lai L. Yip, Michael J. Hopkins, admitted 8/26/2020), but I could not confirm their firms or that any of them touched this matter; do not treat those names as counsel here.

In-house counsel: none disclosed. No Rule 7.1 disclosure statement or corporate disclosure was filed by Lenovo (none was required before dismissal), and no in-house attorney signed anything on this docket.

Recommended verification (single step)

Pull D.I. 6 and D.I. 8 from PACER for No. 1:22-cv-00051-RGA and read the signature blocks; alternatively pull the CM-ECF "Notice of Electronic Filing" recipients for those entries, which will list every attorney and firm that appeared. That will convert the inference above into a confirmed record. Given the case was dismissed 4/21/2022 and terminated, no later appearances exist.

What is not in the record (stated explicitly)

• No sealed filings: the case produced no sealing motions and no protective order. The absence of counsel materials is due to dismissal, not sealing.
• No answer, no counterclaims, no invalidity contentions, no IPR petitions by Lenovo tied to this docket that I located.
• No court opinion issued in this case; Judge Andrews's only substantive act was the 4/21/2022 dismissal order.
