Summary

Cedar Lane '790-family case; the '790/'242 image-processing pair accused against camera products (e.g., Wyze Labs).

Case overview & background

Plain-language overview of the case: parties, accused product, patents at issue, and why the suit matters.

I'll research this case thoroughly before drafting the overview.

Let me dig into the dismissal, the '867 patent, Wyze's profile, and any IPR activity.

Case Overview — Cedar Lane Technologies Inc. v. Wyze Labs, Inc., No. 1:21-cv-01704-RGA (D. Del.)

The parties. Cedar Lane Technologies Inc. is not an operating company. It is a Canadian corporation with a stated principal place of business in Nelson, British Columbia, formed in 2019 and characterized in the Stanford NPE Litigation Database as an "acquired patents" asserter, with no products, R&D, or manufacturing of its own (Stanford NPE Database; complaint in related case, Cedar Lane v. Alps Alpine, W.D. Wash. No. 2:23-cv-00001). Its patents trace to Intellectual Ventures LLC, and its enforcement campaign — launched in May 2019 and run primarily through Isaac Rabicoff of Rabicoff Law LLC, with local Delaware counsel — had surpassed 150 defendants by the time this suit was filed (RPX, Defendant Count In Cedar Lane Technologies's Campaign Ticks Past 150, Jan. 31, 2022). Cedar Lane was reportedly the single most frequent patent plaintiff in the U.S. in 2021 by case count (Lex Machina 2022 report, as summarized in Chinese IP-risk bulletins). The defendant, Wyze Labs, Inc., is a genuine operating company: a privately held, Kirkland, Washington consumer-electronics maker founded in 2017 by former Amazon executives (Yun Zhang, Dave Crosby, Dongsheng Song) that built its business on aggressively underpriced smart-home cameras — the original $20 Wyze Cam — sold direct-to-consumer and monetized through its Cam Plus/Cam Unlimited subscription (CB Insights; company profile). Wyze has raised roughly $145–150 million in venture funding; third-party revenue estimates vary widely (from ~$60M to ~$130M annually) and should not be treated as reliable.

The accused technology and the patents. The complaint (D.I. 1, filed Dec. 2, 2021) accused Wyze in two distinct technology lanes. First, Wyze cameras were alleged to infringe U.S. Patent Nos. 6,972,790 and 8,537,242, both titled "Host interface for imaging arrays" and both naming Mark Suska, with the '790 patent issuing Dec. 6, 2005 on a Dec. 21, 2000 application (originally assigned to Psion Teklogix Systems Inc.) and the '242 patent issuing Sept. 17, 2013 as a divisional. In one sentence each: the '790 patent claims an interface — preferably on the same die as the image sensor — that buffers imaging-array data in a FIFO or addressable memory and signals the host processor (interrupt or bus request) based on how much data has accumulated, decoupling the sensor's fixed clock rate from the processor's; the '242 patent claims the corresponding method — storing image data in a FIFO, maintaining a FIFO counter, comparing it to a FIFO limit, and generating an interrupt to trigger the processor transfer (see the complaint analysis of the parallel Alps Alpine suit). Second, Wyze's support for the Google Assistant platform was alleged to infringe U.S. Patent No. 8,165,867, "Methods for translating a device command" (issued Apr. 24, 2012; Sept. 15, 2000 priority), which claims a method of using one electronic device to control a second, non-co-located device in real time by capturing a human-understandable command, manipulating it, and transmitting it to a remote computer system — i.e., the cloud voice-assistant architecture (RPX, supra; Law Street Media on the parallel Sonos suit). Note a metadata discrepancy: the case report to the Patent Office (D.I. 3 and D.I. 15) lists all three patents — 6,972,790, 8,165,867, and 8,537,242 — so the "patents at issue" field for this case (two patents) appears to understate the complaint by one; the '867 patent was pleaded as a separate count.

Procedural posture and why it matters. This case never became a litigation. It was filed in the District of Delaware (not Cedar Lane's usual W.D. Tex./Judge Albright venue) and assigned to Judge Richard G. Andrews. Service on Wyze was effected Dec. 8, 2021 but then withdrawn over a defect, prompting Judge Andrews to issue an oral order on Jan. 7, 2022 directing plaintiff to explain the missing answer (D.I. 6–8, 10); Wyze waived service on Jan. 7, 2022 with an answer due Mar. 8, 2022 (D.I. 9); Cedar Lane then filed an unopposed motion to stay all deadlines through Apr. 7, 2022 (D.I. 11–12), and on Mar. 22, 2022 filed a notice of voluntary dismissal, which the court entered with prejudice the same day (D.I. 13–14, "Civil Case Terminated"), with the AO-120 report following on Mar. 23, 2022 (D.I. 15) (full docket). Wyze never answered, no motion to dismiss or transfer was decided, there was no claim construction, and no IPR was filed against the '790 or '242 patents that I could locate — though Unified Patents did run a PATROLL crowdsourcing contest on the '867 patent from Jan. 20 to Mar. 1, 2021, awarding $3,000 for prior art in April 2021 (Unified Patents). The ~3.5-month life span, the unopposed stay, and the with-prejudice dismissal are the classic signature of a quick nuisance-value settlement; no settlement or license document is public, so the specific terms are unverified. The case is notable for three reasons: it illustrates Cedar Lane's 2021–22 diversification beyond W.D. Tex. into Delaware, where it filed a cluster of near-identical complaints against consumer-electronics and app companies (e.g., Cedar Lane v. Snap, 1:22-cv-00058-RGA, dismissed with prejudice Jan. 25, 2022) before Judge Andrews; it is a clean data point on a high-volume PAE campaign built entirely on harvested IV patents where the asserted imaging-interface patents carried a database-estimated expiration of Aug. 1, 2023, capping the damages tail and reinforcing the incentive to settle cheaply (see Patsnap/Patsnap litigation summaries); and it sits at the intersection of the smart-home camera market, where the same two imaging patents were asserted against camera makers (Arlo, Basler, Lorex, Vantage) and the '867 patent against voice-assistant implementers, making Wyze's Google-Assistant integration as much the target as its camera hardware.

Sourcing caveats. Docket entries and dates above are corroborated by the Patexia and UniCourt docket reproductions; I did not independently pull PACER images of D.I. 1 or D.I. 13. Wyze's litigation counsel of record does not appear in the retrieved docket (the case closed before any defense appearance is reflected), so I have not named one. Cedar Lane's aggregate filing counts (150+ defendants, ~270 suits, '790 asserted in ~220+ district court cases) come from RPX and third-party patent databases and vary by source and snapshot date; treat them as order-of-magnitude. The named-patent count for this case conflicts with the docket as noted above.

Key legal developments & outcome

Major rulings, motions, claim construction, settlements, and the present posture or final disposition.

I'll research this case across multiple sources. Let me start with several searches.

The case appears to have resolved quickly via voluntary dismissal. Let me verify the full docket and check for related/refiled actions and PTAB proceedings.

Now let me check for any refiled Wyze action, and PTAB proceedings on these patents.

Cedar Lane Technologies Inc. v. Wyze Labs, Inc., No. 1:21-cv-01704-RGA (D. Del.) — Litigation Chronology and Outcome

Bottom line: This was a short-lived, settlement-driven NPE case. It lasted roughly 110 days from filing to a voluntary dismissal with prejudice (2022-03-22), never reaching an answer, counterclaims, Rule 12 practice, Markman, or discovery. There is no trial, no verdict, no judgment on the merits, and no appeal. It is one of the >150 matters in Cedar Lane's Intellectual Ventures-derived campaign, resolved in the ordinary course of that campaign's "file-and-settle" model.


1. Filing and initial pleadings

Date Event Docket
2021-12-02 Complaint for patent infringement filed with jury demand; assigned to Judge Richard G. Andrews (RGA). Accused products: Wyze cameras, and smart-home products supporting Google Assistant (per contemporaneous reporting). D.I. 1
2021-12-02 Rule 7.1 disclosure (no parent/affiliate); Magistrate consent/referral forms; § 290 report to the PTO listing 6,972,790; 8,165,867; 8,537,242 D.I. 2–4
2021-12-02 Summons issued D.I. 5
2021-12-17 "Summons returned executed" — plaintiff reported service on Wyze 2021-12-08, answer due 2021-12-29 D.I. 6

Note on the patents at issue: the case metadata lists only the '790 and '242 image-processing pair, but the complaint and the D.I. 3/15 § 290 reports list three patents — '790, '242, and U.S. Patent No. 8,165,867 (remote device control, the patent asserted against Wyze for Google Assistant functionality). The '790/'242 pair are parent/divisional ("Host interface for imaging arrays"), priority ~January 2000, acquired from Intellectual Ventures. (Patexia docket; Mondaq/RPX, 2022-01-31)

2. Service irregularities and the docket's first (and only) contentious moment

  • 2022-01-07 — Judge Andrews issued an oral order noting no answer had been filed by the 2021-12-29 deadline and directing plaintiff to file a status letter within three days (D.I. 7).
  • 2022-01-10 — Cedar Lane filed a status report and motion to withdraw the affidavit of service (D.I. 8) — i.e., plaintiff effectively conceded its December service return was defective and abandoned it. Simultaneously it filed a waiver of service sent to Wyze on 2022-01-07, resetting the answer deadline to 2022-03-08 (D.I. 9).
  • 2022-01-11 — Order granting the motion to withdraw (D.I. 10).

This service-withdrawal pattern recurs across Cedar Lane's Delaware filings in this period and is a signature of the campaign's volume-based filing practice rather than any merits dispute.

3. Pre-trial motions of substance

None. There was no Rule 12(b) motion to dismiss, no § 1404(a) transfer motion, no motion to stay pending IPR, and no summary judgment motion. No answer and no counterclaims were ever filed by Wyze — the case was terminated before the responsive pleading deadline. The only motions on the docket are the service-related motion (D.I. 8) and an unopposed stay (D.I. 11).

4. Claim construction / discovery / trial

The case never reached any of these stages:

  • Markman: none — no scheduling order, no joint claim construction statement, no Markman hearing.
  • Discovery: no Rule 26(f) conference, no discovery order, no produced documents, no depositions. No strategically significant discovery event exists.
  • Trial/verdict/post-trial: none. No JMOL, new-trial, or § 285 fee motion.

5. The decisive event: stay, then dismissal with prejudice

  • 2022-03-08 — Cedar Lane filed an unopposed motion to stay all deadlines through 2022-04-07 (D.I. 11), granted the same day (D.I. 12). In this campaign, an unopposed stay requested by the plaintiff immediately before a responsive deadline is the standard tell of a settlement/license being papered.
  • 2022-03-22 — Notice of voluntary dismissal (D.I. 13); same-day order granting dismissal with prejudice, civil case terminated (D.I. 14).
  • 2022-03-23 — § 290 patent/trademark report to the Commissioner transmitting the dismissal order (D.I. 15).

Terms of the resolution are not public. Because the dismissal was with prejudice and followed an unopposed stay, the reasonable inference is a paid settlement/license, but no filing discloses an amount, and no consent judgment was entered. For calibration only (not Wyze-specific), Cedar Lane's counsel in a parallel 2022 matter described an "opening demand of 95K" and a desire for portfolio-wide licensing. (The Logic, 2022)

6. Final disposition / present posture

Closed. Termination date 2022-03-22, dismissed with prejudice, no judgment on validity, enforceability, or infringement, and no prevailing-party determination. There is nothing pending in this docket and no Federal Circuit appeal.

No refiled Wyze action located. I searched Cedar Lane's case lists (Stanford NPE database, Patsnap litigation index, Patexia related-case tables) and found no second Cedar Lane suit against Wyze Labs; Wyze appears only as a past target in retrospective reporting. I could not exhaustively confirm this, so treat "no refiling" as a reasonably supported but not airtight negative.

7. Parallel PTAB proceedings

I could not verify any IPR/PGR on the '790 or '242 patents, and none is reflected in this docket — no stay motion, no PTAB-related status report, and no Federal Circuit PTAB appeal. Two caveats, flagged as unverified because my search budget was exhausted before I could run targeted PTAB docket queries (PTAB P-TACTS / Unified Patents portal):

  1. A Chinese-language campaign analysis reports that the only successful invalidation against Cedar Lane's portfolio was an IPR filed by Unified Patents, LLC in October 2019, and does not identify the patent as '790 or '242. On that record, the '790/'242 pair has not been cancelled at the PTAB. (gdoip.com, 2022-07-04)
  2. Both asserted imaging patents are old and expiring/expired (priority ~Jan. 2000; '790 estimated expiry 2023-08-01 per that same source), which materially reduces both the value of the license and the incentive for any defendant to file an IPR. This is a plausible reason no PTAB petition appears in this case — but that inference is my analysis, not a documented fact.

Because no IPR was instituted or even, so far as I can find, petitioned on these two patents during the case's four-month life, PTAB proceedings had no effect on this litigation.


Analytical takeaway

This case is analytically thin on the merits and thick on portfolio strategy. Its value to a litigant-side reader is as a data point on Cedar Lane's Delaware practice in late 2021–early 2022:

  • Venue choice: filed in D. Del. before Judge Andrews rather than W.D. Tex. before Judge Albright (where Cedar Lane filed contemporaneous '790/'242 suits against Qualcomm, Avis, Lorex, etc.), consistent with a defendant-by-defendant venue calculus.
  • Speed: ~110 days filing-to-dismissal; ~74 days from waiver of service. This matches reported ~90-day average dispositions across the campaign and explains why no Cedar Lane case produced claim construction worth citing.
  • Precedential value: none. The dismissal with prejudice means there is no district court or Federal Circuit authority on the '790/'242 claims from this case; any invalidity or non-infringement analysis must come from the handful of matters that went further (and the 2019 Unified Patents IPR on a different Cedar Lane patent).
  • Why it dried up: Cedar Lane's filing volume collapsed in 2023 amid Chief Judge Connolly's third-party-litigation-funding disclosure requirements and the approach of patent expiry — relevant context if you are assessing whether Wyze (or similarly situated defendants) faces renewed exposure. Given the '790's ~2023 expiry and the finality of the with-preferential dismissal, renewed assertion against Wyze on these two patents appears foreclosed.

Sourcing note: the chronology above is drawn from the PACER-derived dockets reproduced by Patexia and UniCourt and cross-checked against RPX/Mondaq campaign coverage. Docket entry numbers and dates are reliable; the substance of the settlement, the precise claim charts (Exhibits 1–6 to D.I. 1), and the PTAB status are not documented in the sources I could reach, and I have marked them accordingly rather than inferring specifics.

Plaintiff representatives

Counsel of record for the plaintiff(s): attorneys, firms, and roles (lead counsel, of counsel, local counsel).

I'll research the counsel of record for Cedar Lane Technologies in this case.

Now let me verify deBruin's firm and whether other counsel (e.g., Rabicoff) appeared.

Let me pull the actual docket via CourtListener and confirm deBruin's firm at the time.

Counsel of Record — Plaintiff Cedar Lane Technologies Inc.

Bottom line: Only one attorney ever appeared for the plaintiff on this docket. Cedar Lane filed pro se through its Delaware counsel, David W. deBruin, then voluntarily dismissed the case with prejudice roughly 3½ months later — before any defendant appearance or answer (D.I. 13–14, Mar. 22, 2022). There is no plaintiff in-house counsel of record (Cedar Lane is a British Columbia NPE whose sole director is Gregory Benoit, a non-lawyer patent monetization consultant).

Plaintiff's counsel

Attorney Role Firm / Office Notes
David W. deBruin (Del. Bar No. 4846) Lead and only counsel of record; also functioned as local counsel Gawthrop Greenwood, PC, 3711 Kennett Pike, Suite 100, Wilmington, DE 19807 · (302) 777-5353 · ddebruin@gawthrop.com Wilmington patent litigator who served as Cedar Lane's standing Delaware counsel across the campaign's D. Del. filings. Signed every plaintiff-side filing here, including the complaint (D.I. 1), the Rule 7.1 disclosure (D.I. 4), the status report/motion to withdraw the affidavit of service (D.I. 8), the unopposed motion to stay (D.I. 11), and the notice of voluntary dismissal (D.I. 13), all under the Gawthrop Greenwood signature block.

Firm-change caveat: deBruin's Gawthrop Greenwood affiliation is confirmed for this case by contemporaneous signature blocks in the Cedar Lane Delaware filings (e.g., Cedar Lane v. Fantasia Trading, No. 1:21-cv-01428-RGA, D.I. 7 & 11; Cedar Lane v. Snap, 1:22-cv-00058). Law360's attorney profile now lists him at Napoli Shkolnik (Wilmington, DE) in connection with later Cedar Lane matters (e.g., Cedar Lane v. Openeye US, filed Nov. 17, 2022) — i.e., he appears to have moved firms after this case closed in March 2022. I have not independently verified the exact date of the move.

Counsel who did not appear here (important negative finding)

  • Isaac Rabicoff (Rabicoff Law LLC, Alexandria, VA; formerly Chicago) was Cedar Lane's de facto national lead counsel in this campaign — he filed the Waco/Texas complaints and appeared in the D. Del. cases in which he was admitted pro hac vice (e.g., Cedar Lane v. Livexlive Media, D. Del., where he is listed as "Pro Hac Vice admission pending"). I found no notice of appearance by Rabicoff in No. 1:21-cv-01704, and the available docket text reflects only deBruin as plaintiff's attorney. Given the case died at the pleading stage, that is unsurprising. Flagging this as apparent absence from the record as mirrored on UniCourt/Patexia/Justia, not a certified PACER negative.
  • No defendant counsel for Wyze Labs appears on the docket — consistent with dismissal before an answer was due.

Experience notes and a caveat you should carry forward

  • deBruin's practice is high-volume Delaware patent docket work; this Wyze case is one of dozens of Cedar Lane D. Del. matters in which he was the sole signatory. His relevance to the substance of this case is essentially procedural only — no substantive advocacy appears on this docket.
  • Rabicoff — while not of record here — is the architect of the Cedar Lane campaign and carries a documented disciplinary history that bears on any assessment of Cedar Lane's litigation conduct: Judge Vince Chhabria sanctioned him $1,000 under Rule 11 and referred him to the N.D. Cal. Standing Committee on Professional Conduct in Cedar Lane Techs. Inc. v. Blackmagic Design Inc., No. 20-cv-01302-VC (N.D. Cal. Nov. 19, 2020), for frivolous Rule 15 arguments, misleading statements, and failing to appear; the Standing Committee's Jan. 24, 2022 report resolved the referral with a $9,193 pro hac vice fee payment undertaking. That history is in the public record and, per press reporting, arose from the same Cedar Lane campaign.

Sourcing / verification status

The docket detail above is drawn from third-party mirrors (UniCourt case page for 1:21-cv-01704; Patexia document list; Justia dockets for related Cedar Lane cases), not a direct PACER pull, and I did not retrieve the complaint's signature block itself — deBruin's authorship is inferred from the filer tag on D.I. 1 and his signature on the later filings. No sealed filings or sealed appearances are indicated. If you need a certified counsel list, a PACER docket report for 1:21-cv-01704 (D. Del., closed 3/22/2022) will resolve it in one step.

Defendant representatives

Counsel of record for the defendant(s): attorneys, firms, and roles (lead counsel, of counsel, local counsel).

I'll research the counsel of record for Wyze Labs in this case using web searches.

Let me verify the docket directly, since the Patexia summary suggests no answer was ever filed.

The docket summary suggests no defense appearance was ever entered. Let me confirm against CourtListener/RECAP and check whether the waiver-of-service filing names defense counsel.

Headline finding: there is no counsel of record for Wyze Labs in this case

This is not a case where filings are sealed or counsel simply hasn't appeared yet. No attorney ever entered an appearance for Wyze Labs in D. Del. C.A. No. 1:21-cv-01704-RGA, and the case closed before any responsive pleading was filed. I could not identify a single defense attorney of record, and I am declining to name anyone as such rather than infer from related litigation.

Docket basis (the full 15-entry docket)

The docket is unusually short and every substantive filing was made by plaintiff's counsel:

D.I. Date Filing Filed by
1 12/02/2021 Complaint for patent infringement (jury demand); asserts 6,972,790; 8,165,867; 8,537,242 deBruin (pltf)

Sources: Patexia docket for 1:21-cv-01704 (https://services.patexia.com/lawsuits/Cedar-Lane-Technologies-Inc-v-Wyze-Labs-Inc-id-[159815](/patent/159815)/documents); UniCourt mirror of the PACER docket (https://unicourt.com/case/pc-db5-cedar-lane-technologies-inc-v-wyze-labs-inc-[1089751](/patent/1089751)).

Key inferences from that record:

  • No D.I. numbered entry is a notice of appearance, answer, Rule 12 motion, or corporate disclosure by Wyze. In D. Del. practice, an appearance would appear as its own docket entry, and Wyze's Rule 7.1/3.1 disclosures would have generated a docket line. There is none.
  • Wyze waived formal service rather than appearing (D.I. 9). A waiver of service under Fed. R. Civ. P. 4(d) is filed by the plaintiff and requires no appearance by defendant's counsel. That waiver form (Ex. to D.I. 9) is the one document in the record that would likely bear a defense attorney's signature, and its signatory is not reflected in any docket text or secondary source I could access. That is the specific gap in this research — I could not retrieve the imaged PDF of D.I. 9.
  • The case resolved by pre-answer negotiated dismissal. The March 8 unopposed stay (~30 days) followed by a with-prejudice dismissal two weeks later is the classic signature of the Cedar Lane settlement script — the same pattern as the campaign-wide ~96% settlement rate reported by IAM (https://www.iam-media.com/court/us-district-court-for-district-of-delaware) and the $95K opening demand described by Cedar Lane's own counsel in The Logic (https://thelogic.co/news/b-c-firm-sues-torontos-ecobee-in-texas-court-thats-become-a-go-to-for-ip-litigation/). Wyze's counsel, if any, would have been engaged only in settlement correspondence, off-docket.

Corollary worth noting for the case file

The absence of any defense appearance is itself a point of contrast with Wyze's other patent matters, where it litigates hard:

  • Sensormatic Electronics v. Wyze Labs (D. Del. 1:19-cv-01543-CFC-SRF) — Wyze fought to a "complete victory" per Cooley LLP's own announcement (https://www.cooley.com), and Wyze petitioned for IPR (IPR2020-01490 on U.S. Pat. 8,610,772), serving invalidity contentions in April 2020.
  • Hepworth v. Wyze Labs (W.D. Wash. 2:22-cv-00752) — Eric J. Weiss and Mallory Gitt Webster of Perkins Coie (Seattle) entered appearances (D.I. 7, 06/21/2022) (https://www.courtlistener.com/docket/63353561/hepworth-v-wyze-labs-inc/).
  • Wheeler v. Wyze Labs (W.D. Wash. 2:26-cv-01319) — Steven Rich appeared for Wyze (D.I. 8, 05/12/2026).
  • Multimodal LLC v. Wyze Labs (D. Del. 1:23-cv-00763) and Be Labs v. Wyze Labs (D. Del. 1:23-cv-00553) — again no defendant counsel of record, both resolved by early voluntary dismissal.

So the "no appearance" outcome here is a recurring feature of Wyze's NPE docket, not an anomaly.

What I would do to close the gap

  1. Pull the imaged PDF of D.I. 9 (waiver of service) in PACER — the Rule 4(d) form typically identifies the signatory attorney and firm, even without a formal appearance. This is the only realistic path to naming a defense attorney for this specific case.
  2. Check the Sensormatic matter's later docket for whether Cooley/Perkins Coie were on a standing engagement for Wyze patent defense in 2021–22, and cross-reference Cedar Lane's settlement correspondence in produced licensing files (Cedar Lane's demand letters and email chains have surfaced in other defendants' filings).

Bottom line for the litigation history section: record it as "no appearance by defendant; waiver of service (D.I. 9) followed by voluntary dismissal with prejudice (D.I. 13–14) on March 22, 2022, before any responsive pleading" — and attribute no counsel rather than crediting any firm.
