Cedar Lane Technologies Inc. v. Phytech US, Inc.

I'll research this case and its context before writing the overview.

Case Overview

Parties. Cedar Lane Technologies Inc. is a Canadian patent-holding company — a non-practicing entity in the Stanford NPE Litigation Database's "acquired patents" category, headed by president Greg Benoit, which buys portfolios and monetizes them through high-volume, fast-settling infringement suits (IAM interviewed Benoit in March 2023 on Cedar Lane's practice as "America's top-filing NPE," citing a roughly 96% settlement rate among its terminated cases). Its Delaware counsel of record here was David W. deBruin. Defendant Phytech US, Inc. is the U.S. sales arm of Phytech Ltd., an Israeli agtech firm whose commercial offering is plant-based irrigation management: stem-diameter (dendrometer) and fruit-size sensors, soil-moisture probes and weather data, feeding a "plant status"/stress-alert software platform sold to growers on a per-season, hardware-retained service model. Phytech is a small operating company, not a litigant with a patent portfolio of its own; the docket reflects no answer, counterclaim, or IPR activity. One naming caution: the Unified Patents portal titles this case "Cedar Lane Technologies Inc v. Phytech Ltd," while the Delaware docket names "Phytech US, Inc."; it is a different defendant from Phytec America LLC, the German embedded-imaging vendor Cedar Lane separately sued in W.D. Wash. (No. 3:22-cv-05134).

Patents and accused technology. The complaint reported two patents to the USPTO: U.S. Patent No. 6,972,790 and U.S. Patent No. 8,537,242, both titled "Host interface for imaging arrays" (inventor Mark Suska; '790 issued Dec. 6, 2005 from a Dec. 21, 2000 application with Jan. 21, 2000 priority; '242 issued Sept. 17, 2013 as a divisional of the '790 application and terminal-disclaimed over it). Technically, the '790 claims an interface — preferably integrated on the same die as a CMOS image sensor — that buffers pixel data in a FIFO/addressable memory, generates an interrupt or bus-request signal to the host "in response to the quantity of data in the memory," and lets the processor pull data at its own rate, eliminating "glue logic" between a sensor's video-style output and a processor's address-based bus; the '242 claims the same disclosure through a divisional. (Your case metadata lists only the '790; the docket's AO-120 report and the Patexia/Unified docket entries show both patents, so treat '242 as also asserted unless the complaint says otherwise.) I could not retrieve the Phytech complaint or its claim-chart exhibits, so the specific accused products and asserted claims are unverified; given the claims are image-sensor interface apparatus claims, the accused technology would necessarily be a camera/image-sensor-bearing Phytech device or system, but that is inference, not a sourced fact.

Posture, venue, and significance. Filed January 13, 2022 in the District of Delaware and assigned to Judge Richard G. Andrews (D. Del. No. 1:22-cv-00054-RGA), it was one of a same-day cluster of Cedar Lane complaints before him (with Nos. 1:22-cv-00050 (EPIX), -00051 (Lenovo), and -00058), part of the wave that pushed Cedar Lane past 150 defendants by late January 2022. Service was effected January 20; when no answer appeared by the February 10 deadline, Judge Andrews issued an oral order requiring a status letter, and Cedar Lane instead filed a notice of voluntary dismissal on February 14, which the court so ordered February 15, 2022 — a 33-day case. Because no answer had been filed, the dismissal was procedurally a Rule 41(a)(1)(A)(i) dismissal (presumptively without prejudice); the docket does not state terms, and no public record of a license, covenant, or payment is available, so the reason for the precipitous dismissal is unknown. Delaware mattered here as Cedar Lane's secondary forum — the NPE's stated preference was W.D. Tex., and Delaware offered a familiar patent bench, Judge Andrews's individual practice requirements, and consolidation of the parallel filings — while Phytech's small-agtech profile fits the classic campaign economics: a low-cost complaint against a company for which defense costs dwarf any settlement. The '790 is a high-volume asset (vendor trackers record roughly 52 suits asserting it, against camera, security, semiconductor and — notably — rental-car and enterprise defendants), and Cedar Lane's other patents have drawn PTAB scrutiny (e.g., Unified Patents, LLC v. Cedar Lane, where the Board held the independent claim of U.S. 7,173,177 unpatentable on Feb. 12, 2021); by contrast, I found no PTAB challenge to the '790/'242 family in available sources (Patsnap records "validity challenges: none"), so this case's significance lies in the campaign pattern rather than in any contested ruling — it produced no opinion, no claim construction, and no validity decision.

Sourcing caveat. Docket events, party names, judge, and dates are corroborated by the Unified Patents litigation portal, DocketBird, and Patexia docket records. Party business descriptions come from Phytech's own marketing materials and IAM's March 2023 profile of Cedar Lane. The complaint PDF and exhibits were not retrievable, so accused-product and asserted-claim specifics remain unverified; patent-expiry data (est. Aug. 1, 2023; RPX lists the '790 as expired) and litigation-count figures are third-party vendor estimates. I found no Law360, Reuters, or court-opinion coverage of this specific case.

I'll research this case across docket sources, PTAB records, and legal news.

Now let me check PTAB proceedings on the two asserted patents and the broader Cedar Lane campaign.

Let me verify PTAB activity and the dismissal terms, plus the parallel Phytec America case.

Bottom line

This case never left the pleading stage. It was a two-page, 33-day existence: complaint filed 2022-01-13, defendant served 2022-01-20, no answer ever filed, and a plaintiff's notice of voluntary dismissal filed 2022-02-14 and so-ordered 2022-02-15. There is no Markman, no discovery, no dispositive motion practice, no trial, and no appeal. Any litigation analysis of this docket is therefore really an analysis of Cedar Lane's mass-assertion campaign and of why this particular defendant exited the campaign within days — not of adjudicated merits.

Category-by-category: what happened, and what did not

Filing & initial pleadings. Complaint only (D.I. 1, 2022-01-13). No answer, no counterclaims, no Rule 12(b) motion, no third-party practice. Cedar Lane's D. Del. filings in this period were captioned against "Phytech US, Inc." and pleaded direct infringement plus induced infringement by end users, with claim charts attached as exhibits — the same template it used in Cedar Lane v. Snap, 1:22-cv-00058 (D. Del.) and the W.D. Tex. cases. Plaintiff's Delaware counsel was David W. deBruin (Gawthrop Greenwood); the campaign's Texas/federal-court filings were handled by Isaac Rabicoff (Rabicoff Law LLC), later joined by Napoli Shkolnik.

Pre-trial motions of substance. None. No motion to dismiss for improper venue or failure to state a claim, no § 1404(a) transfer motion, no motion to stay pending IPR, no summary judgment motion. The only filings after the complaint were the related-case disclosure letter (D.I. 7) and the dismissal papers.

Claim construction. Never reached. No scheduling order, no § 282 disclosures, no Markman briefing, no claim construction hearing or order.

Discovery. None. No Rule 26(f) conference, no ESI order, no discovery disputes.

Trial / verdict / post-trial motions. None. No JMOL, new trial, or § 285 fee motion. Because the case ended by notice of dismissal before an answer, no fee-shifting or exceptional-case record was created.

Final disposition. Voluntary dismissal, so ordered 2022-02-15 by Judge Andrews (D.I. 10), with the Patent/Trademark Report docketed the same day (D.I. 11). Caveat on prejudice: the free docket text for D.I. 10 reads simply "SO ORDERED Granting [9] Notice of Voluntary Dismissal," whereas the contemporaneous order in the companion Snap case expressly reads "With Prejudice" (Cedar Lane v. Snap, 1:22-cv-00058, D.I. 7, 2022-01-25). That contrast suggests the Phytech dismissal was without prejudice (or at least did not specify prejudice), but the text of D.I. 9 is not in the public free record, so I'd verify against PACER before relying on it. There was no appeal — nothing appealable existed.

Parallel PTAB proceedings. For the two asserted patents, I found no IPR or PGR. Third-party databases record "validity challenges: none recorded" for both US 6,972,790 and US 8,537,242 (Patsnap patent/litigation record; same for the STMicroelectronics case record). Accordingly, no PTAB proceeding had any effect on this litigation — there was no stay motion and no Fintiv/§ 315 issues.

The only Cedar Lane PTAB matter I could confirm is on a different patent: Unified Patents, LLC v. Cedar Lane Technologies Inc., IPR2020-00006 on U.S. 7,173,177 (playlist/UI patent), instituted 2020-03-18 and decided 2021-02-12 with claims held unpatentable (Unified Patents; RPX). That decision is relevant to Cedar Lane's overall portfolio credibility in 2022 but has no claim-preclusive or estoppel effect on the '790/'242 family. Negative finding caveat: my PTAB search was not exhaustive (no direct PTAB Endpoint/PATR query), so treat "no IPR" as a strong-but-unconfirmed negative.

Strategic reading of the record

1. The dismissal looks reactive, not negotiated. The sequence is unusually stark: answer due 2022-02-10 → no appearance or answer → Judge Andrews' sua sponte oral order of 2022-02-11 requiring a status letter within three days → notice of dismissal filed 2022-02-14. A plaintiff that intended to pursue the case would ordinarily seek an extension or move for default; Cedar Lane instead exited. Whether that reflects service on the wrong affiliate, a quick low-value license, or a decision to re-file elsewhere is not established by any source I found — the docket does not say.

2. Identity confusion is a plausible but unproven explanation. "Phytech US, Inc." appears to be the U.S. arm of Israeli ag-tech/plant-sensing firm Phytech Ltd. (Unified Patents captions this very case as Cedar Lane v. Phytech Ltd), whereas Cedar Lane separately sued the unrelated German-origin imaging/embedded-vision company Phytec America LLC in W.D. Wash., 3:22-cv-05134, on the same '790 patent (per Stanford NPE database, patent 6,972,790, which lists both). Whether the Delaware defendant was simply the wrong target is my inference from the parallel case and the 33-day collapse — flag as unconfirmed.

3. This docket is one cell in a very large campaign. Cedar Lane asserted '790/'242 against roughly 200+ defendants across D. Del., W.D. Tex., E.D. Va., W.D. Wash., W.D. Pa., and elsewhere. Within the same January 2022 Delaware batch: Cedar Lane v. Metro-Goldwyn-Mayer, 1:22-cv-00014 (dismissed 2022-01-12), Cedar Lane v. Snap, 1:22-cv-00058 (dismissed with prejudice 2022-01-25,

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

Counsel of Record for Plaintiff Cedar Lane Technologies Inc. — 1:22-cv-00054-RGA

Bottom line: Only one attorney ever appeared of record for the plaintiff in this case. The docket is just 11 entries long (complaint 1/13/2022 → dismissal 2/15/2022), and every plaintiff-side filing was made by a single Delaware attorney. There were no pro hac vice motions, no additional notices of appearance, and no other counsel entries before the case closed, so there is no "lead / of counsel / in-house" multi-lawyer structure to report here.

Attorney of record

Docket proof of the appearance

• D.I. 6 (1/26/2022) — Summons Returned Executed, filed by deBruin on behalf of Cedar Lane.
• D.I. 7 (2/10/2022) — Letter to Judge Andrews "from David W. deBruin, regarding disclosure of related cases" (the response to the Court's related-case/litigation-funding scrutiny of the Cedar Lane batch).
• D.I. 9 (2/14/2022) — Notice of Voluntary Dismissal "by Cedar Lane Technologies Inc. as to Phytech US, Inc. (deBruin, David)."
• D.I. 10 (2/15/2022) — Order granting D.I. 9; case terminated.
• Docket sources: DocketBird docket sheet; Patexia document list; Unified Patents litigation portal.

Defendant's counsel (for completeness — no appearance was ever filed)

Phytech US, Inc. never answered (answer was due 2/10/2022) and never entered an appearance on the docket before dismissal. That is why Judge Andrews issued the 2/11/2022 oral order requiring a status letter and why Cedar Lane dismissed the next business day. I cannot identify defense counsel — none is of record.

Sourcing caveats

• Complaint signature block not directly reviewed. I was unable to open the D.I. 1 PDF for this particular case. In parallel Cedar Lane complaints the signature block is the Gawthrop Greenwood address for deBruin, and the docket's filing attorney is deBruin, so the conclusion is well grounded — but if the D.I. 1 caption lists any additional non-Delaware filer, that person still never made an appearance and would not be counsel of record. D. Del. Local Rule 83.5(d) requires Delaware counsel to be the CM/ECF filer for all papers, which is exactly how this docket reads.
• Nothing in this case is sealed; the record is simply thin because the case was dismissed 33 days after filing.
• One metadata discrepancy worth flagging for the case profile: the D.I. 11 Patent/Trademark Report and the original D.I. 3 report list two patents — U.S. Patent Nos. 6,972,790 and 8,537,242 — while the case metadata supplied lists only the '790 patent. The complaint asserted both (consistent with the other January 2022 Cedar Lane filings, e.g., 1:22-cv-00050 and -00051). See the D.I. 11 docket text ("Report to the Commissioner of Patents and Trademarks for Patent/Trademark Number(s) 6,972,790; 8,537,242").
• No parallel PTAB/IPR activity against the '790 or '242 patents by Phytech was located; the patents were part of Cedar Lane's acquired portfolio (originally tied to Intellectual Ventures-related assets per IPWatchdog's Jan. 20, 2022 round-up), and this defendant resolved by walk-away dismissal rather than an IPR.

I'll verify the defendant's appearance history against docket sources before concluding.

Let me check for any additional docket entries or related appearances, and whether Phytech entities appeared through counsel in any parallel Cedar Lane suit.

One more check: whether Phytech was named in any other patent suit (which would reveal retained counsel), and whether any firm lists Phytech as a patent-litigation client.

Bottom line

No attorney ever appeared for the defendant in this case — there is no counsel of record to identify. Phytech US, Inc. was served on January 20, 2022, never answered (answer due February 10, 2022), never filed a notice of appearance, a pro hac vice motion, a Rule 12 motion, a corporate disclosure statement, or any other paper, and the case was dismissed on Cedar Lane's notice three business days after Judge Andrews prompted the plaintiff about the missing answer. The docket is only 11 entries long, and every single filing was made by the plaintiff or the court.

Docket proof of the absence

Complete docket, 1:22-cv-00054-RGA (Jan. 13 – Feb. 15, 2022), with filer attribution:

Sources: Unified Patents litigation portal, 1:22-cv-00054 (full docket text including the 2/11 oral order); DocketBird docket sheet; Patexia document list (document-by-document listing; no defense filings appear). Three independent docket aggregators return identical entry lists — there is no "gap" in which an appearance could be hiding.

Nothing is sealed in this case; the record is thin because it closed in 33 days, not because anything was filed under seal. There were no protective orders, no redactions, and no ex parte filings that could conceal an appearance.

What I checked and did not find

• No notice of appearance. Under D. Del. practice, an out-of-state defendant's first paper is typically a Notice of Appearance by Delaware counsel plus a pro hac vice motion. Neither exists here.
• No answer, counterclaim, or Rule 12(b) motion. The court's own 2/11/2022 oral order is affirmative evidence of this: "An answer was due to be filed on 2/10/2022 (see D.I. 6), and to date none has been filed."
• No corporate disclosure statement / Rule 7.1 filing by Phytech. Only Cedar Lane's D.I. 4 disclosure exists — notable because a subsidiary of an Israeli parent would have had to identify Phytech Ltd. under Rule 7.1(a)(2).
• No stipulation or extension. Unlike the companion case Cedar Lane v. EPIX, No. 1:22-cv-00050-RGA, where the defendant obtained a stipulated extension (D.I. 7, so ordered 1/28/2022, resetting the answer to 3/12/2022), nothing analogous was filed for Phytech. That contrast is meaningful: an engaged defendant's counsel was actively managing deadlines in the same batch, before the same judge, in the same week.
• No defense-side appellate or PTAB activity attributable to Phytech, and no parallel litigation in which Phytech's litigation counsel is named. PlainSite's entity profile for Phytech Ltd. records no litigation; my searches of D. Del., W.D. Wash. (the Phytec America case, 3:22-cv-05134), and general docket aggregators surfaced no other suit in which Phytech appeared through counsel.
• No firm website or Law360/Reuters report listing Phytech as a patent-litigation client. None found; absence of evidence, not proof of absence, but combined with the docket it is unsurprising.

Useful contrast: who did appear for other defendants in the same Cedar Lane batch

This is worth stating because it shows the negative finding is case-specific rather than an artifact of thin coverage of Cedar Lane's January 2022 wave:

So the same defense-side patent bar was in fact entering appearances against Cedar Lane in Delaware and elsewhere in this period; Phytech simply never retained and caused an appearance to be filed before Cedar Lane walked away. (I have not independently verified the firms of McNabnay/Wyatt/Anderson from firm websites in this search — treat firm affiliation as unconfirmed; their roles and pro hac vice status are docket-sourced.)

Caveats and how to close the gap definitively

1. Counsel may have existed without appearing. It is entirely possible — indeed likely, given the speed of the dismissal — that Phytech's insurer or Israeli parent retained counsel who communicated with Cedar Lane's counsel off-docket (a demand-response letter, a tolling or standstill agreement, or license discussions), producing the 2/14 dismissal. Nothing in the public record identifies any such attorney, and I will not name one. The dismissal notice itself (D.I. 9) is filed by plaintiff's counsel only.
2. Procedure required no appearance. Because no answer or Rule 12 motion was served, Cedar Lane could dismiss as of right under Rule 41(a)(1)(A)(i); a defendant need not appear to be dismissed out. The absence of defense counsel is therefore legally unremarkable, not evidence of default or sanction.
3. Caption/service nuance that may explain the non-appearance. The complaint names Phytech US, Inc. (a Delaware-formed entity with a California registered agent, C T Corporation System, per California SOS records), and service was effected domestically in 7 days. Had the intended target been the Israeli parent Phytech Ltd. — as Unified Patents' portal caption suggests — service would have run through the Hague Convention and months, not a week. Either way, the record shows no appearance.
4. To verify to a certainty, pull the PACER docket report (D. Del., filed 1/13/2022, closed 2/15/2022) — the "Attorneys" pane and party/termination screen will show an empty defense-side attorney list. Given the three aggregators agree and the case is closed, PACER is unlikely to add anything.
5. Practical takeaway for any case analysis: because no defense counsel appeared, there is no defense-side privilege log, no joint-defense or common-interest arrangement on this docket, no removal or transfer briefing, and no basis to infer Phytech's litigation strategy from the record. Any narrative attributing a strategy to Phytech's counsel would be unsourced.
