Cedar Lane Technologies Inc. v. Vantage Robotics, Inc.

I'll research this case across multiple sources before drafting.

Excellent — key finding already: there appear to be two Delaware suits against Vantage. Let me dig deeper.

Case Overview & Background

The parties and the two-suit pattern. Plaintiff Cedar Lane Technologies Inc. is a Canadian (British Columbia) patent monetization entity incorporated on April 29, 2019, with attorney/licensing executive Greg Benoit as director and a registered address corresponding to IP licensing firm Pigott & Co.; its asserted patents passed to it from Intellectual Ventures through the Delaware intermediary Steephill Technologies LLC. Stanford's NPE Litigation Database classifies Cedar Lane's assertions as "Acquired patents," and it is routinely described as one of the most prolific filers in the country — IAM reported it as the top-filing NPE of 2022, with a roughly 96% settlement rate among terminated cases (Stanford NPE DB; IAM, Mar. 20, 2023; Seyfarth "NPE Showcase"). Defendant Vantage Robotics is a small but strategically significant Silicon Valley drone maker (San Leandro, CA), whose products — Snap (the first drone to obtain an FAA waiver for commercial flight over people), Vesper, and Trace — are NDAA‑compliant, DoD Blue UAS-cleared ISR platforms sold to the Army, Navy, Marines, Air Force, Coast Guard, FBI and NASA, and which competed in the Army's Short Range Reconnaissance program (company overview; SBIR profile). Notably, this was Cedar Lane's second Delaware suit against the same company: it first sued Vantage Robotics, LLC in Cedar Lane Techs. v. Vantage Robotics, LLC, No. 1:22-cv-01406 (D. Del., filed Oct. 26, 2022), then voluntarily dismissed that case on March 22, 2023 (D.I. 10–11) and re-filed four days later against Vantage Robotics, Inc. as No. 1:23-cv-00336 — a dismiss-and-refile-against-the-correct-entity maneuver that preserved continuity of filing before the patents ran out.

The asserted patents. The complaint's Rule 3 Report to the Commissioner lists two patents, not one: U.S. Patent No. 6,972,790 ("Host interface for imaging arrays," issued Dec. 6, 2005; inventor Mark Suska; priority Jan. 21, 2000) and U.S. Patent No. 8,537,242 (same title, issued Sept. 17, 2013, a continuation-style method patent) (D.I. 3). Technically, the family claims a hardware interface block between an image sensor's imaging array and a host processor: a FIFO/addressable memory buffering pixel data clocked in at the sensor's rate, a counter and comparator that trip an interrupt or bus-request signal when the buffer reaches a threshold, and circuitry that then drains the data out at the processor's rate — the classic "sensor runs faster than the CPU can read" problem, with the interface preferably integrated on the sensor die. The '790 apparatus claim is representative: memory + signal generator responsive to data quantity + control circuit; the '242 method claim recites receiving image data, storing in FIFO, updating a FIFO counter, comparing to a FIFO limit, and generating an interrupt (see the Ex Parte complaint analysis). In practice Cedar Lane asserted this family against camera, surveillance, and imaging-pipeline defendants broadly — GoPro, Hasselblad, Arashi Vision/Insta360, onsemi, Amazon, STMicroelectronics and dozens of security-camera vendors (IPWatchdog roundups; Stanford '790 case list). One caveat worth flagging: the complaint did not name specific accused products on its face — it incorporated claim-chart exhibits by reference — so the precise Vantage product(s) charted (most plausibly the camera/gimbal imaging pipeline in Snap/Vesper) is something I could not verify from public filings.

Procedural posture and venue. Filed March 26, 2023 in the District of Delaware, assigned to Judge Richard G. Andrews with related case 1:23-cv-00337 (D.I. 1, 6); Vantage was served March 29, 2023, and its answer deadline was extended to June 5, 2023 by unopposed motion (D.I. 8, So Ordered Apr. 19, 2023). On May 17, 2023, Paul J. Napoli wrote to Judge Andrews regarding dissociation of Napoli Shkolnik LLC from plaintiff's counsel (D.I. 9), leaving David W. deBruin to prosecute. The case terminated October 31, 2023, when Cedar Lane filed a Rule 41(a)(1)(A)(i) notice voluntarily dismissing all claims, each side bearing its own costs; the reported notice text specifies dismissal with prejudice (PatSnap case record) — I could not independently pull the notice itself from PACER to confirm that "with prejudice" wording, and note the earlier '1406 dismissal was reported as without prejudice, so the refiling sequence matters. Delaware was a deliberate choice: Cedar Lane opened a large D. Del. batch in late October 2022 (1:22-cv-01402 et seq.) even though W.D. Tex. was its 2022 venue of preference, and Vantage (a Delaware-formed entity) was clearly amenable to suit there — Delaware offering a knowledgeable patent bench, a fast § 101 docket, and, for a defendant, the prospect of fee-shifting and transfer pressure.

Why this case is notable despite its short life. Three things. First, timing against patent expiry: the '790 patent's estimated expiry was August 1, 2023 (20 years from the January 2000 priority date, subject to any PTA), meaning it lapsed roughly five months after filing and two months before the dismissal — so the case was, from the outset, a last-window damages play whose value decayed weekly, which helps explain both the rapid, pre-answer dismiss-and-refile against the correct corporate entity and the eventual walk-away. Second, target selection and asymmetry: an NPE with a documented ~96% settlement rate pressed a 20-year-old IV-derived sensor-interface patent on a ~30–40 person defense-tech supplier during a period when that supplier was scaling into Army SRR and CHS-6 programs, $20M+ in DoD R&D funding, and a 2025 corporate investment from ideaForge — a classic low-cost, high-leverage nuisance-value posture against a company whose real exposure was procurement distraction rather than a plausible damages award. Third, the absence of any merits testing: no answer, no claim construction, no § 101 ruling, and — in the sources reviewed — no IPR or PGR ever filed against either the '790 or '242 patent, so the family's validity and scope remain entirely untested even though it was asserted against dozens of defendants. Contrast Unified Patents' successful IPR against a different Cedar Lane IV patent (U.S. 7,173,177, held unpatentable Feb. 12, 2021), which illustrates that targeted PTAB challenges can break pieces of this portfolio while district-court defendants like Vantage simply bought their way out (Unified Patents). The net result: a 219-day case with a substantively thin public record, closed with (reportedly) prejudice, and no precedent on a patent family that remains part of the drone/imaging FTO landscape.

Sourcing note: Docket entries above are drawn from the Justia/Patexia docket transcriptions of D. Del. 1:23-cv-00336 and 1:22-cv-01406 and from PatSnap's case records; I did not have live PACER access, and the case-metadata line listing only the '790 patent is incomplete relative to D.I. 3, which lists both '790 and '242. The identity of the specific accused Vantage product and the exact notice-of-dismissal language are the two facts I'd want PACER to confirm before relying on them in a filing.

I'll research this case systematically, starting with the docket and the asserted patent.

The case appears short-lived. Let me pull the full docket and verify the dismissal terms, which two sources describe inconsistently.

Two Vantage cases exist (a 2022 LLC case and the 2023 Inc. case at issue). Let me pin down the docket for the 2023 case, especially whether an answer/counterclaims were filed and the exact dismissal.

Cedar Lane Techs. Inc. v. Vantage Robotics, Inc., No. 1:23-cv-00336 (D. Del.)

Bottom line: This was a short, thin, early-exit case. It ran 219 days (2023-03-26 → 2023-10-31) and terminated by Cedar Lane's own Rule 41(a)(1)(A)(i) notice of dismissal with prejudice, each side bearing its own costs and fees. There was no answer or counterclaim on the public record, no Rule 12 motion, no transfer or stay motion, no Markman, no summary judgment, no discovery dispute of note, no trial, no JMOL/new-trial/fee motion, no appeal, and no PTAB proceeding on the asserted patents. Everything below is ordered chronologically, with the analytical gaps flagged.

---

1. Filing and initial pleadings (2023-03-26)

• 2023-03-26 — Complaint (D.I. 1) filed in D. Del. with jury demand; filing fee $402. Attachments: four exhibits (Ex. 1 = the '790 patent; Ex. 2 = the '242 patent; Exs. 3–4 supporting), Appearance of Counsel, Civil Cover Sheet. Cause of action: 35 U.S.C. § 271.
• Patents asserted: the case metadata lists only U.S. Patent No. 6,972,790 ("Host interface for imaging arrays," issued 2005-12-06). In fact two patents were pleaded: the '790 and U.S. Patent No. 8,537,242 (a divisional of the '790, issued 2013-09-17), per D.I. 3 (Report to Commissioner of Patents listing "6,972,790; 8,537,242") and the complaint's own recitation of "Patents-in-Suit." Both are Cedar Lane acquisitions (Stanford NPE database categorizes Cedar Lane as asserting "Acquired patents").
• D.I. 2 magistrate-consent/referral forms; D.I. 3 Patent/Trademark Report; D.I. 4 Rule 7.1 disclosure (no parents or affiliates); D.I. 5 summons issued 2023-03-27.
• Theory of infringement (from the complaint, as analyzed in secondary sources and parallel Cedar Lane complaints): direct infringement plus induced infringement (product literature/website materials instructing end users) and post-service willfulness based on "actual knowledge of infringement" acquired on service, with a § 285 exceptional-case and fee prayer. Notably, the complaint did not plead claim charts as filed exhibits — it incorporated by reference "Exemplary '790/'242 Patent Claims" charts. Representative claim 1 of the '790 requires (a) a memory storing imaging-array data and clocking signals at a rate set by the clocking signals; (b) a signal generator generating a signal to the processor system "in response to the quantity of data in the memory"; and (c) a circuit controlling transfer out of the memory at a rate determined by the processor system. That "in response to the quantity of data" limitation is the natural infringement fault line (buffer-count/high-water-mark trigger vs. end-of-line/end-of-frame signals) — but it was never litigated or construed here.
• 2023-03-29 — case assigned to Judge Richard G. Andrews (initials "RGA" required on all filings); docket notes associated cases 1:23-cv-00336-UNA and 1:23-cv-00337-UNA, i.e., this was part of a multi-defendant filing wave in Delaware.
• 2023-04-10 — D.I. 6, 7 summons returned executed: Vantage served 2023-03-29; answer due 2023-04-19.
• 2023-04-19 — D.I. 8 Cedar Lane's unopposed motion to extend Vantage's response deadline; SO ORDERED the same day, resetting answer/response to 2023-06-05. This is the last substantive pre-dismissal docket entry that reflects engagement by the defense.
• Answer / counterclaims: I found no answer, amended answer, or counterclaim in any retrievable docket record. Two independent litigation databases (PatSnap, Patexia) record the termination date and mechanism but list no answer or counterclaim event. I could not retrieve PACER/CourtListener images after 2023-05-17 (the Justia docket snapshot is "last retrieved on May 17, 2023"), so I cannot affirmatively exclude filings in the 2023-05-17 → 2023-10-31 window. However, Cedar Lane's reliance on Rule 41(a)(1)(A)(i) — available only before service of an answer or a summary-judgment motion — is itself strong record evidence that no answer was served. Treat "no answer/counterclaims" as well-supported but not visually verified against the imaged docket.

2. Counsel change with strategic significance (2023-05-17)

• 2023-05-17 — D.I. 9: letter to Judge Andrews from Paul J. Napoli, Esq. regarding dissociation of Napoli Shkolnik LLC from plaintiff's counsel. Cedar Lane's Delaware filings were handled by David W. deBruin (local counsel), while the campaign's national counsel was a Rabicoff Law LLC / Napoli Shkolnik pairing. The Napoli Shkolnik withdrawal roughly five weeks before the extended answer deadline is consistent with the case being re-routed or wound down rather than pressed; the public record does not state a reason, and I will not speculate further than that.

3. Pre-trial motions of substance — none

• No Rule 12(b)(6) motion, no motion to dismiss for improper venue or want of jurisdiction, no § 1404(a) transfer motion, no motion to stay pending IPR, no motion for judgment on the pleadings, no summary-judgment motion, and no discovery motions appear on the record. The only motions were the unopposed extension (D.I. 8) and the ultimate dismissal.
• Strategic read: For a well-funded NPE campaign facing an accused drone/robotics maker, the absence of a transfer motion, an IPR stay motion, or an early § 101 challenge is the most informative negative fact in the docket. It suggests the case never reached the point where Vantage's counsel had to commit to a defensive strategy — consistent with a quick, low-friction resolution.

4. 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 '790 and '242 claims were never construed by any court. The key disputed phrase ("in response to the quantity of data in the memory") therefore remains unadjudicated — a genuine open risk for anyone else in the imaging-interface space.

5. Discovery milestones — none of record

• No Rule 26(f) report, no protective order, no ESI order, no contention interrogatories, no expert reports, no fact- or expert-deposition disputes. The case terminated before the discovery period opened in any documented way, which is why the public record contains no infringement contentions, no invalidity contentions, and no damages theory.

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

No trial, no verdict, no JMOL, no Rule 59 motion, no Rule 54(d)/§ 285 fee motion. No merits determination of any kind — no non-infringement judgment, no invalidity judgment, no unenforceability holding.

7. Final disposition (2023-10-31)

• 2023-10-31 — Notice of voluntary dismissal under Fed. R. Civ. P. 41(a)(1)(A)(i). The recorded operative text, quoted verbatim from the docket:

  "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 Vantage Robotics, Inc. Each party shall bear its own costs, expenses, and attorneys' fees."

  The case was terminated the same day (D. Del. "Case Terminated"). Duration: 219 days. Presiding judge: Chief Judge Richard G. Andrews.

• Why with prejudice: a Rule 41(a)(1)(A)(i) dismissal is without prejudice by default, so the affirmative "with prejudice" recital is a deliberate term. Coupled with the mutual cost/fee waiver, this is the signature of a **negotiated, no-payment-or-nominal-payment walk-

I'll research plaintiff-side counsel of record from the docket and firm sources.

Counsel of record for Plaintiff Cedar Lane Technologies Inc. — D. Del. 1:23-cv-00336

Bottom line: The docket on this case is effectively a one-lawyer docket. Every plaintiff-side filing retrievable from the record is signed by David Walter deBruin, then of Napoli Shkolnik LLC's Wilmington, Delaware office — he is the only attorney recorded as counsel of record for Cedar Lane in this case. The Cedar Lane campaign's national filer, Isaac Phillip Rabicoff (Rabicoff Law LLC), is the attorney who ran Cedar Lane's cases nationally and was named on contemporaneous Cedar Lane complaints in other districts, but I found no appearance, pro hac vice motion, or signature by Rabicoff in this docket — so he should be described as campaign counsel, not counsel of record here. Paul J. Napoli appears only through the 5/17/2023 dissociation letter (D.I. 9), which is a firm-withdrawal communication, not an appearance on Vantage's behalf (the prior section correctly flags that this entry is frequently misread in aggregator summaries).

Table of plaintiff-side counsel

No in-house counsel for Cedar Lane appears on this docket. Cedar Lane has no legal department in the ordinary sense — its principal is licensing executive/attorney Greg Benoit (per the earlier background section), and its enforcement is entirely outsourced to outside counsel.

One-line experience notes (patent litigation)

• David W. deBruin — A Delaware-licensed NPE/patent plaintiffs' lawyer who has served as local counsel or counsel of record in dozens of Delaware patent suits for monetization plaintiffs, including Cedar Lane (multiple Delaware defendants, e.g., Cedar Lane v. Openeye, v. Opticon, v. Turing Video, v. Hubbell, v. TVL International), BE Labs v. Belkin, Rothschild Broadcast Distribution Systems v. Blackboard (1:21-cv-00627, Rule 41(a)(1)(A)(i) dismissal with prejudice), Cassiopeia IP v. Barco, Tranquility IP v. Kontron, InvesTrex v. News Corp., and Adaptive Headlamp Technologies v. Hyundai. His firm affiliation moved over the relevant period — Gawthrop Greenwood PC (through ~2021, ddebruin@gawthrop.com), The deBruin Firm LLC, then Napoli Shkolnik LLC (2022–2023), which is the affiliation on this filing.
• Isaac P. Rabicoff — The volume filer behind Cedar Lane's national campaign; IAM/the Seyfarth NPE Showcase identified him as filing sixteen Cedar Lane complaints in a single week in W.D. Tex. in September 2022, and Chinese IP-center analysis reported Rabicoff Law LLC handling 58 Cedar Lane suits. Relevant caution for any diligence file: in Cedar Lane Techs. v. Blackmagic Design Inc., No. 20-cv-01302 (N.D. Cal.), Judge Vince Chhabria sanctioned Cedar Lane and Rabicoff — Rabicoff $1,000 under Rule 11 and the court's inherent authority, with a referral to the N.D. Cal. Standing Committee on Professional Conduct for filing patent suits without pro hac vice admission (Nov. 19, 2020 order; subsequent committee report at No. 20-mc-80206).
• Paul J. Napoli — Managing partner of Napoli Shkolnik PLLC, a mass-tort/plaintiffs' firm; his appearance in this record is limited to the dissociation letter and he has no identifiable role as an advocate in the patent case.

Sourcing caveats and contradictions to flag

1. Firm attribution for deBruin is date-sensitive and sources conflict. PatSnap records "David W. deBruin" with "Firm: Not recorded" for this case; Law360 and PatSnap's records for sibling Cedar Lane Delaware cases list Napoli Shkolnik LLC; older records list Gawthrop Greenwood or The deBruin Firm LLC. I use Napoli Shkolnik LLC (Wilmington) as the affiliation at filing because the December 1, 2022 Cedar Lane v. Lexmark complaint — same campaign, same patents, same judge — carries his Napoli Shkolnik signature block, and D.I. 9 (5/17/2023) concerns Napoli Shkolnik's dissociation. What I could not verify: whether deBruin personally moved firms between the 5/17/2023 letter and the 10/31/2023 dismissal, and thus which firm name appears on the dismissal signature block.
2. The docket is truncated. The Justia snapshot for 1:23-cv-00336 was "last retrieved on May 17, 2023," so anything filed between late May and October 31, 2023 (including the dismissal notice and its signature block) is not visible in free sources. A pro hac vice motion by Rabicoff, had one been filed, would likely fall in that window. I cannot affirmatively exclude it — but no PHV motion appears in any retrieved entry, including the Patexia and PatSnap transcriptions, and the earlier "no defense appearance" section's reasoning (Rule 41(a)(1)(A)(i) availability) does not bear on Rabicoff either way.
3. Attachment numbering conflicts between mirrors. Justia lists D.I. 1's attachments as "#5 Appearance of Counsel, #6 Civil Cover Sheet," while CourtListener's entry lists "#5 Civil Cover Sheet, #6 Appearance of Counsel" and adds the Rule 7.1 statement and Patent/Trademark Report as attachments. The "Appearance of Counsel" attachment is the document that would definitively name every appearing attorney; I could not open it. That is the single highest-value PACER pull for this task.
4. Nothing is sealed. No sealing order or sealed document appears in any retrieved record for this case; the null result on counsel is a function of docket truncation, not confidentiality.

Recommended verification step: pull the PACER docket sheet for 1:23-cv-00336 (all entries, including D.I. 10+) plus D.I. 1 attachments 5/6 ("Appearance of Counsel") and the 10/31/2023 dismissal notice, and check the signature blocks and any pro hac vice orders nunc pro tunc. If the Appearance of Counsel lists only deBruin, the correct statement for a diligence file is: sole counsel of record — David W. deBruin (Napoli Shkolnik LLC, Wilmington, DE); campaign counsel Isaac P. Rabicoff (Rabicoff Law LLC) did not appear.

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

Let me pull the full docket and check whether defense counsel ever appeared.

Bottom line: no defendant's counsel of record can be identified — Vantage Robotics appears never to have appeared in this case

I searched the aggregator dockets (Justia, CourtListener, Patexia, PatSnap, ExParte/PACER-derived), the Stanford NPE database entry, and news/firm sources. I found no attorney listed as counsel of record for Vantage Robotics, Inc. in D. Del. 1:23-cv-00336. I am not going to name anyone speculatively.

What the docket shows

Sources: Justia docket (https://dockets.justia.com/docket/delaware/dedce/1:2023cv00336/81866, last retrieved 5/17/2023); Patexia case summary (terminated 10/31/2023, "Dismissed – Voluntarily," https://services.patexia.com/lawsuits/Cedar-Lane-Technologies-Inc-v-Vantage-Robotics-Inc-id-[187893](/patent/187893)); PatSnap litigation record quoting the Rule 41(a)(1)(A)(i) dismissal verbatim (https://www.patsnap.com/resources/blog/litigation/cedar-lane-technologies-v-vantage-robotics-patent-litigation-patsnap/); Stanford NPE Database (https://npe.law.stanford.edu/case/[270324](/patent/270324)).

Why I conclude there was no defense appearance

1. Every substantive filing in the accessible docket is plaintiff-side. The 4/19/2023 extension was an unopposed motion filed by plaintiff's counsel David W. deBruin — the standard Cedar Lane practice of papering over a defendant that has not retained Delaware counsel. A represented defendant would typically have filed its own extension or a Rule 12 motion, or at minimum a notice of appearance under D. Del. Local Rule 83.5(d) (local counsel requirement).
2. Aggregator "counsel of record" fields are blank on the defense side. PatSnap's party table lists David W. deBruin for Cedar Lane and no attorney for Vantage Robotics; the ExParte PACER-derived case page for 1:23-cv-00336 likewise surfaces no defendant attorney.
3. No firm, court opinion, or Law360/Reuters item links any attorney to defending Vantage in this matter. Vantage (San Leandro, CA) is a small defense-tech UAS maker; earlier public materials list corporate/IP advisors (e.g., Orrick for corporate, Knobbe Martens for IP) in a 2017 pitch deck, but that is corporate/prosecution context, decades-old-adjacent and not a litigation appearance — I would not treat it as counsel of record here.
4. The case ended by unilateral notice of dismissal with prejudice rather than by answer, motion, or stipulation signed by defense counsel — consistent with a defendant that never appeared and a plaintiff that resolved/settled outside the litigation.

Important sourcing caveat

Free dockets for this case are incomplete: the Justia snapshot stops at 5/17/2023, and the case lived another five-plus months. It is therefore possible a notice of appearance, waiver of service, or Rule 12 motion was filed between late May and October 2023 and is not reflected in free sources. To confirm the null result definitively, pull the full PACER docket sheet (D. Del. 1:23-cv-00336, D.I. 10 onward, including the 10/31/2023 notice of dismissal and any accompanying signature blocks) or a CourtListener RECAP docket. I could not access PACER directly. No filing in this case is known to be sealed.

Corroborating pattern (same defendant, adjacent cases)

• Cedar Lane Techs. v. Vantage Robotics, LLC, 1:22-cv-01406 (D. Del., filed 10/26/2022) — same patents; terminated in 147 days; public docket also shows only plaintiff-side activity (deBruin).
• Iron Bird LLC v. Vantage Robotics LLC, 1:25-cv-00213 (D. Del., filed 2/20/2025) — PACER-derived listing records "No Defendant Attorneys" (https://ai-lab.exparte.com/case/dct/ded/1:25-cv-00213/iron-bird-llc-v-vantage-robotics-llc).

That three-case pattern supports the inference that Vantage has typically resolved these NPE suits without entering an appearance — but each of those dockets carries the same incompleteness caveat.

For completeness: plaintiff's side (not asked, but relevant to the "unopposed" filings)

• David W. deBruin — Delaware counsel for Cedar Lane; filed the complaint, the extension motion, and the dismissal notice (D. Del. bar; frequent local counsel in Cedar Lane's Delaware NPE campaign).
• Paul J. Napoli (Napoli Shkolnik LLC) — D.I. 9 letter re: dissociation of Napoli Shkolnik from plaintiff's counsel (5/17/2023), i.e., plaintiff's own prior counsel withdrew/was dissociated; this is not a defense-side entry and is sometimes misread as such in aggregator summaries.

Recommendation: treat "defendant's counsel of record" as none identified / none appeared unless the full PACER docket (docs. 10+) shows otherwise. Given the Rule 41(a)(1)(A)(i) dismissal with each side bearing its own fees, the practical answer for a diligence file is that Vantage was, on the available record, unrepresented in the litigation.
