Let me verify the earlier Amlogic suit, the accused products, and any PTAB proceedings.

Case Overview

Parties. Cedar Lane Technologies Inc. is a Canadian entity with a principal place of business in Nelson, British Columbia — a fact it pleaded in its parallel complaints ("a corporation organized and existing under the laws of Canada that maintains its principal place of business at 560 Baker Street, Suite 1, Nelson, BC V1L 4H9," e.g., Cedar Lane Techs. v. Alps Alpine N. Am., No. 2:23-cv-00001 (W.D. Wash.), D.I. 1 ¶ 2). It is a non-practicing patent assertion entity: the Stanford NPE Litigation Database classifies Cedar Lane under the "acquired patents" asserter category, and it has no products of its own; one third-party litigation-tracking blog tags its portfolio as an "IV selloff," though I could not independently verify the original assignee chain. Cedar Lane ran one of the highest-volume assertion campaigns of 2022–2023 (Lexology's retail patent reports repeatedly list it among "frequent filers"), staffed principally by Isaac Rabicoff (Rabicoff Law LLC) in W.D. Tex. and by John C. Phillips Jr. and Megan C. Haney of Phillips, McLaughlin & Hall PA in Delaware. Amlogic is a fabless system-on-chip designer whose chips sit inside smart TVs, set-top boxes, and AIoT/smart-vision devices; its U.S. operating arm is Amlogic, Inc. (San Jose, CA). Two naming discrepancies matter: the case metadata caption reads "Amlogic Co. Ltd.," but the Delaware docket named Amlogic, Inc., and Cedar Lane's earlier, related suit named Amlogic Shanghai Co., Ltd. Notably, no defense counsel appears of record in the Delaware case — Amlogic apparently never answered or appeared.

Asserted patents and accused technology. The complaint (D.I. 1, filed 10/31/2023) and the AO-120 form (D.I. 3) list two patents, not one: U.S. Patent No. 6,972,790 and No. 8,537,242, both titled "Host interface for imaging arrays." The '790 patent (filed Dec. 21, 2000; issued Dec. 6, 2005; inventor Mark Suska; prosecuted by McAndrews Held & Malloy) claims an interface — preferably on the same die as the sensor — that buffers imaging-array data in a FIFO or addressable memory and, based on the quantity buffered, generates an interrupt or bus-request signal to a host processor, decoupling the sensor's fixed clock rate from the processor's asynchronous reads. The '242 patent (issued Sept. 17, 2013; a divisional filed Oct. 27, 2005) claims methods of that data flow: receiving image data, storing it in a FIFO, updating a FIFO counter, comparing the count to a FIFO limit, and generating an interrupt (claim 1) or a bus-request signal to a bus-arbitration unit (claim 8). In substance, Cedar Lane alleged that Amlogic's SoCs implement this sensor-to-host FIFO/handshake path — the complaint relies on claim charts in Exhibits 3 and 4 (the latter aimed at inducement of downstream OEMs through Amlogic documentation and reference designs). Caveat: the product-level charts were filed as exhibits I could not retrieve in full, so the specific accused Amlogic part numbers are not verified here. Two datings are economically decisive: Patsnap's record shows an estimated expiry of Aug. 1, 2023 for the '790 (i.e., it had already lapsed when the Delaware suit was filed) and Jan. 22, 2025 for the '242 (roughly fourteen months of remaining term at filing).

Procedural posture and significance. Cedar Lane filed in the District of Delaware — a favored venue for PAEs post-TC Heartland given its patent-specialized bench, registration-based venue hooks, and local-counsel infrastructure — and the case was assigned to Judge Richard G. Andrews (D.I. 6, Nov. 1, 2023), the same judge who handled Cedar Lane's January 2022 Delaware wave. Amlogic was served Nov. 22, 2023 (D.I. 7); Cedar Lane itself moved to extend the answer deadline (D.I. 8), which was so-ordered Dec. 11, 2023, resetting the answer to Feb. 12, 2024. On April 17, 2024, Cedar Lane filed a Rule 41(a)(1)(A)(i) notice dismissing with prejudice, each side bearing its own costs and fees — a self-effectuating dismissal that operates as res judicata against Amlogic, Inc. on these claims. The case lasted 169 days, produced no answer, no Markman, no summary-judgment ruling, and no merits adjudication of validity or infringement; the settlement/license terms, if any, are not public, so any characterization of the dismissal as a paid license would be speculation. Three features make it worth noting. First, it is a re-filing: Cedar Lane had sued Amlogic Shanghai on the same two patents in W.D. Tex. before Judge Albright (Cedar Lane v. Amlogic Shanghai Co., Ltd., No. 6:22-cv-01140, filed Oct. 31, 2022), let it sit unserved/undefended for a year, drew an order to show cause on Oct. 24, 2023, dismissed without prejudice on Oct. 26, 2023, and re-filed against the U.S. affiliate in Delaware five days later. Second, the target selection is notable: Cedar Lane's roughly 52-case assertion record on the '790 patent is dominated by camera, security-surveillance, and end-user defendants (Security Camera Warehouse, Provision-ISR, RaySharp, Longse, Zenitel, Videotec, Speco, Leica Camera, ZKTeco, Socionext, STMicroelectronics, Ricoh, Lexmark, Xerox, Hertz/Enterprise/Avis/Sixt, Qualcomm, Snap, Voxx), so pressing the silicon supplier rather than its OEM customers is the supply-chain-leverage variant of the model. Third, the terminal economics explain the short life: with the '790 already expired and the '242 facing a 2025 cliff, the recoverable past-damages window (six years under § 286) and the absence of any forward injunctive value created strong incentives for a cheap, fast exit. On IPR linkage, my searches located no PTAB proceeding against either patent, and Patsnap records "no validity challenges" for the '790 — consistent with an untested portfolio, but I would characterize that as "none found," not as an exhaustive PTAB verification.

Cedar Lane Technologies Inc. v. Amlogic — Key Legal Developments and Outcome

Case: Cedar Lane Technologies Inc. v. Amlogic, Inc., No. 1:23-cv-01242 (D. Del.), Judge Richard G. Andrews
Patents asserted: U.S. Patent Nos. 6,972,790 and 8,537,242, both titled "Host interface for imaging arrays"
Filed: 2023‑10‑31 (complaint stamped 10/31/2023; the metadata filing date is 2023‑10‑30)
Disposition: Voluntary dismissal with prejudice, 2024‑04‑17, roughly five and a half months after filing — before any answer, counterclaim, motion practice, Markman, or discovery

Bottom line up front: This was not a litigated case in any substantive sense. It was a short-lived NPE assertion that produced zero merits rulings. The entire docket consists of a complaint, service, one extension of the answer deadline, and a notice of dismissal. There is no answer, no counterclaim, no motion to dismiss/transfer/stay, no claim construction, no discovery order, no trial, and no appeal. The strategic story is in the timing — a re-file against the U.S. affiliate after Cedar Lane abandoned its earlier Texas suit against the Shanghai entity, on patents that were expiring or nearly expired — not in any court ruling.

1. Filing and initial pleadings

The complaint (D.I. 1, filed 2023‑10‑31) pled infringement of both the '790 and '242 patents, with exhibits (Exs. 1–4) and a civil cover sheet. Notably, the public complaint did not identify the specific asserted claims, referring instead to "Exemplary '790 Patent Claims" and "Exemplary '242 Patent Claims" in an exhibit. Representative independent claims are claim 1 of the '790 (interface with FIFO buffer, signal generator, and rate-controlled transfer) and claims 1 and 8 of the '242 (method claims culminating, respectively, in an interrupt signal and a bus request signal to a bus arbitration unit — i.e., a DMA-like mechanism). See complaint analysis at ai‑lab‑cl case page.

No answer or counterclaims were ever filed. Amlogic's response deadline was extended once, to 2024‑02‑12, and the case was dismissed before any responsive pleading appeared. Consequently there are no invalidity counterclaims, no non-infringement counterclaims, and no declaratory judgment claims on this docket — an important point, because it means Amlogic obtained no adjudicated clearing judgment; it obtained only a dismissal with prejudice of Cedar Lane's claims.

2. Pre-trial motions of substance — none

There was no motion to dismiss, no § 1404(a) transfer motion, no motion to stay pending IPR, and no summary judgment motion. The only motion filed was the 2023‑12‑11 unopposed extension (D.I. 8). By the time any such motion would have been briefed (spring 2024), the case was over.

Docket quirk worth flagging: the extension motion at D.I. 8 is docketed as "filed by Cedar Lane Technologies Inc." — i.e., by the plaintiff, not the defendant whose deadline was extended. This is either a filing-attribution error in the CM/ECF entry or a joint stipulation uploaded under plaintiff's filer credentials. The order reset "Amlogic, Inc. answer due 2/12/2024," so the substantive effect is clear regardless.

3. Claim construction (Markman) — never reached

No scheduling order, no Joint Claim Construction Statement, no Markman briefing, no Markman hearing, and no claim construction order. The case terminated well before the typical D. Del. Markman stage (which in Judge Andrews's cases with a 2023 filing would have fallen in late 2024 or 2025).

4. Discovery milestones — none

No Rule 26(f) conference, no discovery plan, no protective order, no interrogatories, no document production, no depositions, and no expert reports appear in the record. The case was dismissed roughly five months after filing, before the discovery period would ordinarily open.

5. Trial, verdict, post-trial motions — none

No trial, no verdict, no JMOL, no new-trial motion, no fee motion under § 285, and no bill of costs. The dismissal expressly provided that "[e]ach party shall bear its own costs, expenses, and attorneys' fees" — so the fee-shifting question was contractually resolved in the dismissal itself and never litigated.

6. Final disposition

On 2024‑04‑17, Cedar Lane filed a notice of dismissal stating:

"Plaintiff Cedar Lane Technologies Inc., pursuant to Rule 41(a)(1)(A)(i) of the Federal Rules of Civil Procedure, hereby provides notice that it dismisses with prejudice all claims by Plaintiff against Defendant Amlogic, Inc. Each party shall bear its own costs, expenses, and attorneys' fees."

(Quoted verbatim in the Patsnap case record.)

Practical effect: the dismissal is with prejudice as to Cedar Lane's claims against Amlogic, Inc., so Cedar Lane cannot re-assert the '790 and '242 patents against that entity. It is not a merits judgment — no invalidity or non-infringement holding exists, and the dismissal would not bind Cedar Lane against other defendants or necessarily against Amlogic affiliates.

No appeal. The case is closed; there is no Federal Circuit docket.

Technical note on the rule cited: Rule 41(a)(1)(A)(i) is the unilateral notice-of-dismissal mechanism, which by its terms produces a dismissal without prejudice; a dismissal with prejudice by stipulation is normally effected under Rule 41(a)(1)(A)(ii). Cedar Lane used the (A)(i) vehicle but expressly stated "with prejudice." Courts generally honor the plaintiff's stated intent, so the practical effect here is a with-prejudice dismissal. This is a drafting irregularity in the notice, not a substantive dispute on this d

Counsel of Record for Plaintiff Cedar Lane Technologies Inc. — Cedar Lane Techs. Inc. v. Amlogic, Inc., No. 1:23-cv-01242 (D. Del.)

Docket status caveat up front: This was a short-lived case (D.I. 1 filed 10/31/2023; dismissed with prejudice 4/17/2024 by notice under Rule 41(a)(1)(A)(i), each party bearing its own fees and costs), and the public docket contains only a handful of entries (the Justia mirror was last refreshed 12/11/2023, at D.I. 8). I found no sealed filings and no pro hac vice motions on the public record — but because the docket is thin and partly paywalled, my confidence is high on the two Delaware counsel and only moderate on the extent of national counsel's involvement (see the Rabicoff note below).


1. John C. Phillips, Jr. — Delaware counsel of record (CM/ECF "Lead Attorney" designation)

  • Firm / office: Phillips, McLaughlin & Hall, P.A. (formerly Phillips, Goldman, McLaughlin & Hall), 1200 N. Broom Street, Wilmington, DE 19806 — (302) 655-4200; jcp@pmhdelaw.com. Delaware bar No. 110.
  • Role: The Delaware lawyer who filed and signed the plaintiff's papers — e.g., D.I. 8, the unopposed motion for extension of time to answer (filed 12/11/2023) is docketed as filed by Cedar Lane and entered under "Phillips, John." Docket mirrors list him as plaintiff's "LEAD ATTORNEY / ATTORNEY TO BE NOTICED."
  • Experience note: A fixture of the Delaware patent bar; routinely serves as local/lead Delaware counsel in ANDA and § 271 cases — e.g., Sunoco Partners Mktg. & Terminals L.P. v. Powder Springs Logistics, LLC, No. 17-cv-1390-LPS (D. Del.); Astellas Pharma Inc. v. Lupin Ltd., No. 23-819-JFB-CJB; Galderma Labs. L.P. v. Lupin Inc., No. 21-cv-1710-SB; and more recently Route 92 Medical, Inc. v. Balt USA, LLC (D. Del.) and CHM Industries, Inc. v. Current Lighting Solutions, LLC (D. Del.).

2. Megan C. Haney — Delaware local counsel

  • Firm / office: Phillips, McLaughlin & Hall, P.A., 1200 N. Broom Street, Wilmington, DE 19806 — mch@pmhdelaw.com. Delaware bar No. 5016.
  • Role: Second Delaware counsel of record for Cedar Lane; Justia's party listing for this case shows the plaintiff "Represented By: John C. Phillips, Jr." and "Megan C. Haney," and Patsnap's case record likewise lists the pair as the recorded plaintiff's counsel. Consistent with the firm's standard two-lawyer Delaware appearance in NPE suits (see Patent Armory Inc. v. Reddit, Inc., No. 23-cv-813 (D. Del.), where both are listed for plaintiff).
  • Experience note: Patent/ANDA litigator at the same firm, typically appearing alongside Phillips as local counsel (e.g., Galderma Labs. L.P. v. Lupin Inc.; Astellas v. Lupin; Get Out Ahead, LLC v. Wire Industries; CHM Industries v. Current Lighting).

3. Isaac P. Rabicoff (Rabicoff Law LLC, Alexandria, VA) — reported national/lead counsel; appearance not confirmed on this docket

  • Firm / office: Rabicoff Law LLC, 5680 King Centre Dr., Suite 645, Alexandria, VA 22315.
  • Status in this case — flagged as uncertain: A complaint-level analysis of D.I. 1 describes plaintiff's counsel as "Phillips, McLaughlin & Hall, P.A.; Rabicoff Law LLC," and Rabicoff is Cedar Lane's near-constant national counsel across its campaign (he filed and signed the parallel predecessor suit against Amlogic Shanghai Co., Ltd., No. 6:22-cv-01140 (W.D. Tex.), including its October 2023 voluntary dismissal). However, I could not confirm a notice of appearance, pro hac vice motion, or signature by Rabicoff on the D. Del. docket in 1:23-cv-01242 — the only docketed filer shown in the public mirrors is Phillips. If he participated, he did so behind the Delaware appearance without seeking PHV admission, which is consistent with his documented practice of often not moving for pro hac vice status.
  • Experience note (well documented, mixed): Prolific filer of Cedar Lane's patent suits (hundreds of defendants, largely W.D. Tex. and N.D. Cal.); sanctioned $1,000 under Rule 11 and referred to the N.D. Cal. Standing Committee on Professional Conduct in Cedar Lane Techs. Inc. v. Blackmagic Design Inc., No. 20-cv-1302 (N.D. Cal. Nov. 19, 2020) (Judge Chhabria), and later publicly reprimanded by the State Bar of California (2022) in connection with that conduct. Any assessment of plaintiff-side strategy in this case should account for that history.

4. In-house counsel — none of record

Cedar Lane is a Canadian NPE holding acquired Intellectual Ventures-origin patents; no in-house attorney appeared for plaintiff on this docket.


Practical notes for the case file

  • Caption variance: the case is captioned against "Amlogic Co. Ltd." in the metadata, but the docket and complaint name Amlogic, Inc. (a Delaware corporation, which is the venue hook alleged). The earlier W.D. Tex. suit was against Amlogic Shanghai Co., Ltd. Confirm which entity was served before relying on the caption for preclusion or license-scope analysis.
  • Two patents asserted, one in the metadata: the complaint asserted both the '242 patent and its parent, U.S. Patent No. 6,972,790 ("Host interface for imaging arrays"); the case metadata lists only the '242.
  • No merits adjudication: there was never an answer, motion to dismiss, or Markman — the case ended by unilateral notice of dismissal with prejudice, so there are no claim-construction or invalidity rulings to cite, and no PTAB IPR activity on the '242 located in my search.
