Cedar Lane Technologies Inc. v. Flyability SA

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

Case Overview: Cedar Lane Technologies Inc. v. Flyability SA, No. 1:22-cv-02881 (D. Colo.)

Parties and posture. Cedar Lane Technologies Inc. is a Canadian-incorporated, non-practicing entity formed in 2019 by attorney Greg Benoit; it does not make or sell products and instead monetizes a large acquired patent portfolio (reportedly ~190+ US patents, the large majority acquired), and by 2022 it had filed several hundred infringement suits in US district courts — data compiled by China's Shenzhen IP Protection Center from Lex Machina describes Cedar Lane as the most prolific patent plaintiff in the US in 2021 (source: sziprs.org.cn risk advisory, Oct. 2022). Its near-exclusive outside counsel is Isaac Philip Rabicoff of Rabicoff Law LLC, who filed and appeared in this case (Dkt. 2). The defendant, Flyability, is a Swiss operating company founded in 2014 as an EPFL Lausanne spin-off that makes collision-tolerant indoor inspection drones (the Elios platform) for confined-space industrial inspection in energy, mining, nuclear, and wastewater; it is a well-funded, award-winning commercializer of its own patented robotics technology, not a patent plaintiff (Flyability company page). Cedar Lane filed the complaint on November 3, 2022, alleging infringement under 35 U.S.C. § 271 with a jury demand; the case was assigned to Magistrate Judge Kristen L. Mix in the District of Colorado (Dkt. 1, 5). Cedar Lane filed a notice of voluntary dismissal on November 25, 2022 (Dkt. 11), and on November 30, 2022 Judge Mix dismissed the case without prejudice and vacated the February 2, 2023 scheduling conference (Dkt. 12–13). Total life of the case: 27 days, with no answer, no motion practice, and no substantive ruling. Note a caption discrepancy worth flagging: the D. Colo. docket names the defendant "Flyability Inc.," while the case metadata (and Unified Patents' listing) uses "Flyability SA"; the relationship between the two entities is not documented in the public docket. Caveat: the complaint itself is not available through free sources, so the specific venue and infringement allegations are unverified.

Accused technology and patent. The sole patent in suit here is U.S. Patent No. 8,537,242, "Host interface for imaging arrays" (issued Sept. 17, 2013; application filed Oct. 27, 2005; inventor Mark Suska; prosecution by McAndrews Held & Malloy). The '242 is a divisional in the same family as Cedar Lane's frequently asserted '790 patent, and claims, in essence, an on-chip interface between an image sensor array and a host processor: a buffer that stores imaging-array data at the sensor's clock rate and control logic that issues a signal (an interrupt or bus request) to the processor in response to the quantity of data in the memory, with subsequent transfer clocked at the processor's rate — the FIFO/buffer-plus-ready-signal architecture that bridges a streaming sensor to an addressed bus (patent abstract and claim synopsis as reproduced in Cedar Lane's parallel complaints, e.g., Cedar Lane v. Alps Alpine, W.D. Wash. No. 2:23-cv-00001, Dkt. 1 and third-party complaint analyses at Ex Parte AI Lab). In practice Cedar Lane asserted the '242 against camera-equipped consumer and industrial hardware; the accused instrumentalities in the Flyability case were presumably Flyability's Elios drones with their visual (4K/thermal) payloads. That inference is consistent with Cedar Lane's contemporaneous filings against other drone and imaging-hardware makers (e.g., Cedar Lane v. Vantage Robotics, D. Del. No. 1:22-cv-01406, filed Oct. 26, 2022), but the specific accused product and the asserted claims in this case are set out only in the complaint's exhibits, which are not publicly accessible — Cedar Lane's parallel complaints in this campaign plead "one or more claims" and refer the reader to an external claim chart rather than identifying claims in the body, a pattern that drew criticism in later cases. Note also that the '242's term is near or past expiry: commercial databases list an estimated expiry around August 1, 2023 (derived from the 2000-era priority chain plus adjustment), meaning any recovery window would be narrow and largely retrospective under 35 U.S.C. § 286.

Why it is notable. Three reasons. First, as a litigation-pattern data point: this is a textbook high-volume NPE "nuisance" suit — filed pro se-adjacent in a low-attention venue, never answered, and dismissed without prejudice in under four weeks. Reporting on Cedar Lane's campaign notes that none of its cases has reached trial and that the model is calibrated to produce many modest settlements (see the NPE Showcase profile; Lex Machina data cited by the Shenzhen IP Protection Center puts the median closure at ~77 days, overwhelmingly by settlement). A dismissal without prejudice is consistent with either a confidential settlement/license or a purely tactical retreat, but the docket does not disclose which — no settlement or license document is public. Second, the venue choice matters: D. Colo. is not a habitual Cedar Lane forum (its campaign was concentrated in W.D. Tex. before Judge Albright and in D. Del.), and the plausible reason is that Flyability maintains a US office in Denver alongside Lausanne, Shanghai, and Singapore (Flyability company page), which would support a "regular and established place of business" theory under § 1400(b) — a notable detail because NPEs, lacking a defendant's consent, must satisfy TC Heartland and § 1400(b) to sue a foreign manufacturer in a chosen district. (I have not verified the complaint's venue paragraph, so this is inference, not record fact.) Third, counsel/credibility context: the case sits within a campaign whose lead attorney was sanctioned in 2020 in Cedar Lane v. Blackmagic Design, No. 20-cv-01302-VC (N.D. Cal.), where Judge Vince Chhabria found filings "objectively frivolous" and made in bad faith, fined Rabicoff $1,000, and referred him to the district's Standing Committee on Professional Conduct (sanctions order). On IPR linkage: I found no IPR, PGR, or CBM challenging the '242 that I can confirm from a primary source, and no PTAB proceeding tied to this case; the '242 appears on Unified Patents' patent-specific page only as a litigation-tracking entry, not as a Unified challenge target. The validity defense that a defendant would likely raise (the "in response to the quantity of data in the memory" causal limitation versus end-of-frame or timer-driven transfer) therefore went untested here.

Verification notes. Grounded in the D. Colo. docket (Dkts. 1–13) as mirrored by Justia and UniCourt; Cedar Lane's parallel complaints for patent and claim substance; Flyability's corporate disclosures; and secondary reporting on Cedar Lane's campaign. Not independently verified: the complaint's text and exhibits (paywalled on PACER), the Flyability Inc./SA entity relationship, whether any payment or license accompanied dismissal, and the '242's exact expiration date.

I'll research this case systematically, starting with the docket and case-specific records.

The docket shows an extremely short-lived case. Let me dig into the patent itself and any PTAB proceedings.

Now let me check for PTAB proceedings on the '242 patent and whether Cedar Lane refiled against Flyability elsewhere.

Bottom line

This case never got past the pleading stage. Cedar Lane Technologies Inc. v. Flyability Inc., No. 1:22-cv-02881 (D. Colo.), was filed 2022-11-03 and voluntarily dismissed without prejudice 27 days later, on 2022-11-30. There was no answer, no counterclaim, no motion practice of any kind, no Markman, no discovery, no trial, and no appeal. It is a "file-and-dismiss" case — a single-patent demand letter in docket clothing — not a litigated dispute.

Stage-by-stage answers

Filing & initial pleadings. Complaint filed 2022-11-03, asserting U.S. Patent No. 8,537,242 ("Host interface for imaging arrays," issued 2013-09-17). The '242 is a divisional of U.S. Patent No. 6,972,790 and claims a method of transferring image data from an imaging array to a host processor via a FIFO buffer, a FIFO counter, a comparison against a FIFO limit, and generation of an interrupt signal (see Elec. Compl. ¶ 21-type allegations in Cedar Lane's parallel complaints; e.g., analysis at https://ai-lab.exparte.com/case/dct/wawd/2:23-cv-00001/doc/analysis/1). Cedar Lane pleaded it is "assignee of all right, title and interest" in the '242 — it is an acquired-patent NPE (Stanford NPE Litigation Database classifies Cedar Lane as category "1 – Acquired patents": https://npe.law.stanford.edu/party/cedar-lane-technologies-inc).

Answer / counterclaims: none. No defendant appearance, no Rule 12 response, no counterclaims for invalidity or non-infringement. The docket reflects no return of service and no answer deadline ever set by appearance — a strong indication the case was dismissed before service was completed, though the docket does not state this expressly.

Pre-trial motions of substance: none. No motion to dismiss, no § 1404/§ 1406 transfer motion, no motion to stay pending IPR, no summary judgment motion.

Claim construction: none. No Markman order, no joint claim construction statement, no Indefiniteness/Alice ruling. The case was closed before the Rule 26(f) conference deadline of 2023-01-26.

Discovery: none. No Rule 26(f) report, no initial disclosures, no protective order, no ESI or damages discovery. The most that occurred was the court's scheduling order (Dkt. 10).

Trial / verdict / post-trial motions: none. No JMOL, new trial, or fee motion under § 285. No judgment on the merits was ever entered.

Final disposition. Voluntary dismissal without prejudice under Fed. R. Civ. P. 41(a)(1)(A)(i) — available as of right because Flyability had not yet served an answer or a summary judgment motion. The dismissal is not a merits adjudication: it carries no preclusive effect, no validity finding, and no infringement finding. Cedar Lane retained the right to refile, and no public record shows any payment, license, or covenant.

Appeal: none. No notice of appeal, no Federal Circuit activity.

Parallel PTAB proceedings. My searches identified no IPR, PGR, or CBM involving U.S. 8,537,242 — either against Cedar Lane or by any other petitioner. One commercial patent record (Patsnap) lists the '242 as having "no validity challenges recorded" (https://www.patsnap.com/resources/blog/litigation/cedar-lane-technologies-v-enterprise-holdings-patent-dismissal-patsnap/). Caveat: I was unable to complete an exhaustive PTAB docket query (PTAB Center

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

Let me verify the firm details and check for any additional plaintiff counsel.

Counsel of Record for Plaintiff Cedar Lane Technologies Inc.

Bottom line: the docket discloses exactly one attorney for the plaintiff — Isaac Philip Rabicoff of Rabicoff Law LLC (Chicago) — who signed every plaintiff-side filing (Dkt. 1, 2, 3, 4, 8, 11). No local counsel, no of-counsel, no in-house lawyer, and no other firm appeared for Cedar Lane in this case. No pro hac vice motion was ever filed, and the case was dismissed on the 22nd day.

1. Isaac Philip Rabicoff — sole/lead counsel of record

Notable adverse/disciplinary history (relevant to assessing him as counsel, all publicly sourced):

• Sanctioned and referred, N.D. Cal. (Nov. 19, 2020): In Cedar Lane Techs. Inc. v. Blackmagic Design Inc., No. 20-cv-01302-VC, Judge Vince Chhabria sanctioned Rabicoff $1,000 under Rule 11 and the court's inherent authority, denied his pro hac vice motion, and referred him to the district's Standing Committee on Professional Conduct as a "serial filer" who repeatedly filed patent suits without seeking PHV admission. Order, Dkt. 61 (reproducing the order and the Committee report).
• Standing Committee resolution (Feb. 4, 2022): The Committee's final report required him to pay $9,193 in unpaid PHV fees for 29 N.D. Cal. cases and to seek admission contemporaneously with future complaints.
• Virginia State Bar public reprimand (Nov. 19, 2020), VSB Case No. 22-042-125771, for misrepresentations about his role as "of counsel"/lead counsel and the timing of a hearing; he self-reported the California sanction to the Illinois ARDC in May 2022.

Gaps and caveats you should know about

• No local counsel in D. Colo. D.C.COLO.LAttyR 2 requires membership in the court's bar or PHV admission. The docket contains no motion for pro hac vice admission and no Notice of Entry of Appearance by any Colorado attorney — consistent with this being one of the short-lived filings in which the case resolved (voluntary dismissal 11/25/2022; dismissal without prejudice 11/30/2022, Dkt. 12) before admission was ever perfected. I could not confirm from any source that Mr. Rabicoff is admitted to the D. Colo. bar, so I am not asserting it.
• No defendant-side appearances exist on the docket; Flyability never answered or appeared. (Note the caption discrepancy: PACER/Justia/UniCourt list the defendant as "Flyability Inc.", while your metadata says Flyability SA — I am using the metadata name, but the docket as filed names "Flyability Inc.")
• No sealed filings. The docket contains no sealing orders and no sealed documents; the entire record (13 entries) is public.
• No Law360 or Reuters Legal coverage found for this specific case, and no court opinion issued. The substantive record is Dkt. 1 (complaint with Exs. 1–4) and Dkt. 11–12 (dismissal). Reporting on Rabicoff's practice generally (the Law.com piece above) is the only press coverage I located that touches this matter indirectly.
• Nothing in the pleadings names in-house counsel for Cedar Lane; Cedar Lane (a Canadian NPE) has historically litigated through outside counsel only.

I'll research the docket and any appearances by defendant's counsel.

Counsel of Record — Defendant Flyability

Bottom line: no attorney ever entered an appearance for the defendant in this case. Unlike every other section of this case file, this one has a negative answer, and the negative is well grounded in the docket rather than merely unsourced.

Attorney table

The complete docket (Dkts. 1–13) contains exactly one attorney entry for one party: Isaac Philip Rabicoff, Rabicoff Law LLC (Chicago), who entered his appearance for plaintiff Cedar Lane on the day of filing (Dkt. 2, Nov. 3, 2022) and signed every plaintiff-side filing thereafter (Dkts. 1, 3, 4, 8, 11). Justia's party block shows "Represented By: Isaac Philip Rabicoff" for Cedar Lane only, and UniCourt's "Attorney/Law Firm Details" panel lists a single Plaintiff Attorney and no defendant-side counsel (UniCourt). Patexia's document index for the case (23-cv-02881, id 183152) likewise itemizes no defense filing of any kind (Patexia).

Docket evidence supporting the negative

• No answer and no Rule 12 motion. The case was assigned to Magistrate Judge Kristen L. Mix on Nov. 3, 2022 (Dkt. 5); the summons issued the same day (Dkt. 6); Cedar Lane filed its AO 120 report Nov. 4 and the PTO report went out Nov. 8 (Dkts. 8–9). The next entry after that is Judge Mix's own scheduling order (Dkt. 10, Nov. 17) — no defense pleading intervenes.
• No return of service appears on the docket. The docket shows a summons issued (Dkt. 6) but no executed-return entry before dismissal, and no clerk's entry of default. So there is no record that Flyability was ever served, which is itself the most likely reason no counsel appeared.
• No pro hac vice motions. In D. Colo., out-of-state counsel for a foreign corporate defendant would ordinarily require a pro hac vice motion alongside local counsel under D.C.COLO.LCivR 83.3 — the absence of any such motion confirms no defense-side engagement was formalized.
• No Rule 7.1 corporate disclosure from Flyability. The only disclosure statement on the docket is the plaintiff's (Dkt. 3) — the filing that would have identified the Flyability Inc./SA parent-subsidiary relationship flagged in the case overview as an unresolved caption discrepancy.
• The case ended on plaintiff's initiative. Cedar Lane filed its notice of voluntary dismissal on Nov. 25, 2022 (Dkt. 11) — 22 days after filing, without any docket activity by the defendant — and Judge Mix dismissed without prejudice on Nov. 30, 2022, vacating the Feb. 2, 2023 scheduling conference (Dkts. 12–13).

Who would have appeared (inference, not record)

Because there is no record of defense counsel, anything about Flyability's litigation counsel is speculation. Two data points, both clearly labeled as unverified:

1. Flyability is a Swiss company (Flyability SA, Lausanne) sued under the "Flyability Inc." caption, so any defense engagement would most likely have run through US litigation counsel admitted in D. Colo. with a local firm for the pro hac vice sponsorship. Nothing in the public record identifies which firm Flyability retains.
2. Third-party org-chart aggregators list a "Deputy General Counsel" at Flyability (RocketReach management listing). This is not a court appearance, is not a reliable source, and should not be cited as counsel of record. I found no court filing, firm press release, Law360 or Reuters Legal report identifying any inside or outside counsel for Flyability in this matter.

Cross-reference and verification notes

• This section is consistent with — and reinforces — the case overview's characterization of a 27-day "no answer, no motion practice, no substantive ruling" case. The absence of any defense appearance is the sharpest single data point for the nuisance-suit reading: the dismissal came before Flyability's response deadline machinery was even engaged by service.
• Contrast with Cedar Lane's parallel filings, where the plaintiff's local counsel differed by forum — e.g., David W. deBruin filed the D. Del. complaints (including the near-simultaneous Cedar Lane v. Vantage Robotics, No. 1:22-cv-01406, filed Oct. 26, 2022) — underscoring that the D. Colo. case was Rabicoff-only, with no second chair and no defense-side counterpart.
• Not verified: whether Flyability engaged counsel informally, whether a demand/settlement letter preceded dismissal, and whether any tolling or license agreement accompanied it. No such document is public, and the docket would not reflect it.
• Search coverage: Justia docket mirror, UniCourt, Patexia document index, and general web/Law360-adjacent searches for "1:22-cv-02881" combined with "counsel," "appearance," or "Flyability." All returned only the plaintiff's counsel. PACER itself is paywalled; I did not pull the native docket, but the three independent mirrors agree on the 13-entry docket and its single attorney entry.
