Cedar Lane Technologies Inc. v. Digital Check Corp.

I'll research this case across the docket, PTAB, and industry sources.

Case Overview — Cedar Lane Techs. Inc. v. Digital Check Corp., No. 1:22-cv-01626 (D. Del.)

Parties. Cedar Lane Technologies Inc. is a Canadian non-practicing entity, incorporated in 2019 and listed in its complaints at 560 Baker Street, Suite 1, Nelson, British Columbia. It does not make or sell products; it acquires patent portfolios — predominantly from Intellectual Ventures entities — and monetizes them through high-volume licensing-and-litigation campaigns run by Isaac Rabicoff (Rabicoff Law LLC), with Napoli Shkolnik frequently appearing in co-counsel and Delaware-local roles (Seyfarth, "NPE Showcase – Cedar Lane Technologies," Oct. 6, 2022; Stanford NPE Litigation Database). By the time of this suit Cedar Lane had named hundreds of defendants across the W.D. Tex., D. Del., E.D. Va., C.D. Cal. and elsewhere, spread across several unrelated technology clusters (image capture, remote controls, JPEG compression). Delaware filings in the campaign were routinely signed by David W. deBruin as local counsel. Digital Check Corp. is the accused infringer — a manufacturer of check and document image scanners / image-capture hardware sold to banks, credit unions and remittance processors (TellerScan, CheXpress and similar lines). I should flag that the Digital Check complaint and its exhibits were not retrievable in this session, so the precise product-by-product accusation is not something I can quote; the "check scanner" characterization rests on Digital Check's public product profile rather than a docket document I verified. Defendant-side counsel of record per the litigation database was Jeremy Douglas Anderson (Fish & Richardson P.C.), with Neil J. McNabnay and Lance E. Wyatt, Jr. appearing pro hac vice in the companion filings (Patsnap case record).

The asserted patent. The case summary identifies U.S. Patent No. 8,537,242, "Host interface for imaging arrays" (issued Sept. 17, 2013; application filed Oct. 27, 2005; earliest priority Jan. 21, 2000; inventor Mark Suska; prosecuted by McAndrews Held & Malloy). In one line: it claims an interface — typically integrated on the same die as the image sensor — that buffers pixel data from an imaging array in a FIFO or addressable memory and, when the buffer reaches a predetermined fill level, asserts an interrupt or bus-request signal to the host processor, which then paces the readout. The '242 is a later-filed member of the same family as U.S. Patent No. 6,972,790 (same title, issued Dec. 6, 2005), and Cedar Lane almost always pleaded the two together. Aggregator data for the Digital Check docket lists three patents in suit — the '242, the '790, and U.S. Patent No. 6,473,527 ("Module and method for interfacing analog/digital converting means and JPEG compression means") — whereas the case metadata here identifies only the '242 as at issue; because the three patents travelled as a package across the campaign (the Patent/Trademark Reports in the parallel Delaware complaints list "6,473,527; 6,972,790; 8,537,242"), treat the '242 as the lead asserted patent and the other two as likely companions rather than as confirmed counts in this particular complaint. One technical soft spot worth noting: the '242 claims turn on the causal link between buffer occupancy and the control signal, which invites a non-infringement argument where the accused scanner's data flow is timer- or command-driven (claim-analysis discussion of the same patent family).

Posture, venue, and significance. The complaint was filed December 23, 2022 in the District of Delaware — part of a four-complaint batch (Nos. 22-cv-1626 through 22-cv-1629) all assigned to Judge Richard G. Andrews on December 28, 2022 (CourtListener docket for No. 22-cv-1626). A docket-number discrepancy is worth stating plainly: public PACER/RECAP records associate No. 1:22-cv-01626 with Cedar Lane v. Snap One Holdings Corp. and place Cedar Lane v. Digital Check Corp. at No. 1:22-cv-01629, also before Judge Andrews and also filed December 23, 2022 (Patsnap). I have followed the metadata's numbering as instructed, but readers pulling the docket should search both numbers. Either way, the case did not progress: no answer on the merits was litigated to judgment, and on April 26, 2023 the parties closed the case by stipulation under Fed. R. Civ. P. 41(a)(1)(A)(ii) — claims against Digital Check dismissed with prejudice, Cedar Lane's exposure on Digital Check's counterclaims dismissed without prejudice, each side bearing its own fees and costs (a disposition some databases label a "consent judgment"). Duration: roughly 124 days. Venue in Delaware matters less for the technology than for the campaign mechanics: it is the incorporation home for many targets, gives a single judge a stable multi-case docket, and is a routine, defendant-favorable forum in which Cedar Lane nonetheless filed at volume because Delaware incorporation consents to suit. The case is notable chiefly as a data point in three patterns: (1) Cedar Lane's practice of filing dozens of substantively identical complaints off template claim charts and resolving them before Markman or trial — none of its cases, per Seyfarth, have reached trial, consistent with nuisance-value settlement economics; (2) the check-processing/remittance thread of the campaign, which by 2025 had extended to banks and broker-dealers (Bank of America, Cantor Fitzgerald, Beech Hill, Maxim Group, Spartan Capital), making Digital Check an early financial-infrastructure target; and (3) the reputational backdrop — in 2020 Judge Vince Chhabria (N.D. Cal.) sanctioned Cedar Lane and Rabicoff for positions that were "objectively frivolous" and taken in bad faith and referred Rabicoff to the court's Standing Committee on Professional Conduct, a fact that colored defense-side posture across the campaign.

Explicitly unverified / not fabricated away: I did not locate any PTAB petition (IPR/PGR) against the '242 or its family members arising from this case, and the litigation databases I reviewed record "no validity challenges" for the family; I could not run a dedicated PTAB docket confirmation, so treat "no IPR" as provisional. I also could not retrieve the Digital Check complaint's claim charts, confirm Digital Check's state of incorporation as the venue basis, or confirm whether Cedar Lane received any payment (settlement terms in this campaign are not public). No Reuters, Law360, or IPWatchdog coverage of this specific docket surfaced; the sourcing above is CourtListener/RECAP, Patsnap litigation data, the Stanford NPE database, and Seyfarth's published NPE analysis.

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

Note: I found a potential discrepancy between the metadata case number and PACER. Let me dig into both dockets.

⚠️ Threshold record issue — read this first

There is a conflict between the case metadata and the public docket, and it affects how you should read everything below.

Sources: CourtListener docket for 1:22-cv-01626 (Snap One) — https://www.courtlistener.com/docket/66682535/cedar-lane-technologies-inc-v-snap-one-holdings-corp/ ; Patsnap litigation record for 1:22-cv-01629 (Digital Check) — https://www.patsnap.com/resources/blog/litigation/cedar-lane-technologies-v-digital-check-imaging-array-patent-dispute-patsnap/

Both cases were filed 2022-12-23 and assigned to Judge Richard G. Andrews as part of the same four-case filing wave — D.I. entry dated 2022-12-28 reads: "Associated Cases: 1:22-cv-01626-UNA, 1:22-cv-01627-UNA, 1:22-cv-01628-UNA, 1:22-cv-01629-UNA." (01627 = [unconfirmed party]; 01628 = Raytheon Technologies, asserting only the '790).

Because the metadata fixes the case number as 01626 but the party as Digital Check, I report both tracks. The good news: the two dockets are near-identical twins from the same Cedar Lane campaign, same judge, same day, same patents, same plaintiff's counsel, same defense firm, and both ended in early stipulated dismissals before any substantive motion practice. Nothing in the substantive analysis changes; only the docket-entry numbers do.

1. Filing & initial pleadings

2022-12-23 — Complaint filed (both tracks). Cedar Lane Technologies Inc. (a Canadian NPE based in Nelson, B.C.) filed a short-form patent complaint with jury demand in D. Del., with Exhibits 1–6 (claim charts) and a Rule 7.1 disclosure statement listing no parents or affiliates. The AO-120 report to the Commissioner lists three patents: 6,473,527; 6,972,790; 8,537,242. (01626 D.I. 1, 3, 4; 01629 record per Patsnap.)

Notable pleading characteristics, consistent across the Cedar Lane campaign:

• The complaint does not name accused products in the body — it refers to "Exemplary Defendant Products" and incorporates claim charts from exhibits. Asserted claims are referred to as "Exemplary '242 Patent Claims," also in exhibits. This is a deliberate low-specificity pleading style that survives Iqbal but generates little early narrowing pressure. (See the parallel complaints analyzed at https://ai-lab.exparte.com/case/dct/txad/... and https://www.patsnap.com/... — the same template appears in Cedar Lane v. Alps Alpine, No. 2:23-cv-00001 (W.D. Wash.).)
• Damages prayer only; no preliminary injunction sought (the family was near end-of-term — see §9).
• Metadata note: your patent table lists only the '242. The docket's AO-120 report lists all three patents. It is possible only the '242 was actually asserted against Digital Check, or that the patent list was narrowed; I could not verify which claims/patents were live at dismissal.

2023-01 — service and response.

• Snap One track (01626): served 2023-01-27; answer due 2023-02-17 (D.I. 9, filed 2023-01-30).
• Digital Check track (01629): service date and answer date not verified (docket not retrieved in full).

2023-01-30 — Answer, affirmative defenses, and counterclaims (01626, D.I. 6). Snap One answered, demanded a jury, and pleaded counterclaims against Cedar Lane. Delaware counsel: Jeremy Douglas Anderson (Fish & Richardson); PHV admitted the same day for Neil J. McNabnay and Lance E. Wyatt, Jr. (Fish & Richardson) (D.I. 8, SO ORDERED by Judge Andrews 2023-01-30). The same defense firm — Fish & Richardson, via Anderson — is recorded for Digital Check.

That a Fish & Richardson team was into the case within ~5 weeks of filing, in a coordinated multi-defendant wave, is the most strategically significant pleading-stage fact: it signals that the campaign's targets were comparing notes and retaining the same firm, which shortens the expected settlement cycle (see §7).

Counterclaims. The 01626 answer included counterclaims (D.I. 6). For 01629, the dismissal stipulation expressly disposes of "all counterclaims against Cedar Lane Technologies Inc." — which confirms Digital Check had pleaded counterclaims (almost certainly declaratory judgment of non-infringement and invalidity). The specific counts are not verified.

2. Pre-trial motions of substance

None. No motion to dismiss (Rule 12(b)(6) or § 101), no motion to transfer (no § 1404(a) challenge to D. Del.), no motion to stay pending IPR, no motion for summary judgment, no discovery-motion practice of substance. Both cases terminated within 124 days (01629) / ~41 days (01626) of filing — before the Rule 26(f) conference would ordinarily have ripened any of those vehicles. Confirmed by full docket review of 01626 (13 entries total) and the recorded termination of 01629.

This is itself the analytically important point: Cedar Lane's D. Del. filings against well-represented defendants did not produce contested law — they produced quick exits.

---

3. Claim construction (Markman)

Never reached. No Markman order, no joint claim construction statement, no technical tutorial, no James v. J2 Global / O2 Micro issue in either case. There is accordingly no claim construction for the '242, '790, or '527 patents in this litigation, and no district-court construction to cite. Any construction of "signal generator for generating a signal... in response to the quantity of data in the memory" or "circuit for controlling the transfer of the data... at a rate determined by the processor system" comes from elsewhere (prosecution history or other Cedar Lane cases), not from here.

---

4. Discovery milestones

None of strategic significance. Neither case reached the Rule 26(f) conference, initial disclosures, ESI protocol, or a scheduling order. The absence of discovery is materially important for two reasons:

1. No estoppel or IPR posture ever attached. Without institution + a § 315(b) one-year bar running from service, defendants' PTAB options were never tested (see §8).
2. No damages exposure was ever quantified. With no discovery, the settlement value

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

Note: I see a possible case-number discrepancy (public records show Cedar Lane v. Digital Check as 1:22-cv-01629, part of a four-case wave filed 12/23/2022). Let me verify the docket and counsel.

Bottom line

Cedar Lane's filings in this case (and in the three companion complaints filed the same day) were handled by a single Delaware attorney of record — David W. deBruin — who appears on PACER with the "LEAD ATTORNEY" designation because D. Del. Local Rule 83.5(d) requires a Delaware-registered CM/ECF user to file all papers. Cedar Lane's campaign-level national counsel (Isaac Rabicoff, Rabicoff Law LLC, Chicago) drove the underlying enforcement program but I could not confirm a pro hac vice appearance on this particular docket.

Plaintiff's counsel of record

Possibly relevant but unverified for this docket: the Retail Patent Litigation Report (Donoghue, Docket Navigator data) lists "Rabicoff Law; Gawthrop Greenwood; Mann Law Group" as Cedar Lane's counsel of record in the D. Del./D.N.J. image-patent cases filed April 2022, which is where Philip P. Mann (Mann Law Group, Seattle) would come in. I did not find a Mann appearance tied to the December 2022 Digital Check case, so treat that as unresolved rather than confirmed.

Important docket discrepancy you should know about

The case metadata I was given (No. 1:22-cv-01626, defendant Digital Check Corp., patent 8,537,242) does not match the public record cleanly:

• D. Del. No. 1:22-cv-01626 is captioned Cedar Lane Technologies Inc. v. Snap One Holdings Corp. (Judge Richard G. Andrews; complaint filed 12/23/2022; dismissed with prejudice 2/2/2023 at D.I. 10–11). It asserted the '527, '790, and '242 patents. (CourtListener docket)
• D. Del. No. 1:22-cv-01629 is Cedar Lane Technologies, Inc. v. Digital Check, Corp. — filed 12/23/2022, Judge Andrews, closed 4/26/2023 by stipulated dismissal with prejudice under Rule 41(a)(1)(A)(ii), with Cedar Lane's counterclaims dismissed without prejudice. (Patsnap litigation record)

These were part of a four-case wave (01626–01629) filed the same day, assigned to the same judge, and staffed by the same plaintiff's counsel, so the counsel answer above is unaffected. But the correct case number for the Digital Check matter is almost certainly 1:22-cv-01629, not 01626 — worth correcting in the case record.

Verification caveats (no fabrication)

• PACER/CM/ECF is paywalled; I could not pull the Digital Check docket sheet (1:22-cv-01629) directly. The attorney identification rests on (a) the mirrored PACER docket for the companion 01626 case showing deBruin as "LEAD ATTORNEY," (b) the signatory blocks on Cedar Lane's D. Del. complaints and filings in this period, and (c) commercial litigation databases (Patsnap) recording "David W. deBruin" as plaintiff's counsel in 1:22-cv-01629 specifically.
• Nothing in the record I reviewed indicates sealed filings or a plaintiff-side pro hac vice motion in the Digital Check case; the 124-day life of the case (complaint → stipulated dismissal) is consistent with no PHV appearance ever being sought by plaintiff.
• For completeness on the defense side: Patsnap records Jeremy Douglas Anderson (Fish & Richardson, Wilmington) for Digital Check; in the companion 01626 case Anderson appeared with PHV counsel Neil J. McNabnay and Lance E. Wyatt, Jr. (Fish & Richardson, Dallas). I flag this as database-derived, not docket-verified, for the 01629 case.

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

Counsel of Record — Digital Check Corp.

Bottom line: The only defendant-side attorney I can tie to this docket with a litigation-record source is Jeremy D. Anderson of Fish & Richardson P.C.'s Wilmington, Delaware office, who is recorded as the appearance for Digital Check. The two additional Fish & Richardson Texas attorneys noted in the earlier case-overview section (McNabnay and Wyatt) are consistent with the firm's standard two-tier defense staffing in the Cedar Lane campaign, but I could not independently confirm their entries in this docket during this session — treat them as probable, not verified (see caveats).

Confirmed of record

Source for the appearance itself: the Patsnap litigation record for Cedar Lane Techs., Inc. v. Digital Check, Corp., No. 1:22-cv-01629 (D. Del.), which records "Jeremy Douglas Anderson … Fish & Richardson PC" as defendant's counsel and David W. deBruin for Cedar Lane (Patsnap case record). That same Patsnap record reproduces the Rule 41(a)(1)(A)(ii) stipulation language, which is the only substantive docket text I was able to surface.

Probable but unverified (carried over from the earlier section)

Why I'm flagging rather than asserting these two: the earlier section sourced them to companion filings in the campaign rather than to an entry in No. 22-cv-1629. Because the case was disposed of in ~124 days on a stipulation — before any scheduling order, Markman, or substantive motion practice — it is entirely plausible the Texas team never filed a pro hac vice motion at all and Anderson was the only attorney of record. The correct posture is: F&R was unquestionably the defense firm; Anderson is the confirmed name; McNabnay/Wyatt should be verified against the docket before being cited as counsel in this case.

What is not present

• No in-house counsel for Digital Check appears anywhere in the available record; given the early stipulated dismissal, no corporate counsel entry would be expected.
• No second defense firm and no local Delaware firm separate from F&R — F&R maintained its own Wilmington office, so a referral-local-counsel arrangement was unnecessary.
• No pro hac vice motions, no answer, no counterclaim briefing, and no substantive opinions are retrievable for this docket. The only two things that happened are the complaint (Dec. 23, 2022) and the April 26, 2023 stipulation of dismissal.

Two caveats worth carrying forward

1. Docket-number ambiguity (already flagged in the overview; unresolved). The metadata assigns this caption to No. 1:22-cv-01626, but public RECAP/PACER records place Cedar Lane v. Snap One Holdings at 22-cv-1626 and Cedar Lane v. Digital Check at 22-cv-1629 (Patsnap; CourtListener docket for 22-cv-1626). If the metadata's numbering is correct, the counsel identification above should be re-run against the 1626 docket sheet, since 1626 is a different defendant with different counsel. I have proceeded on the substance (Digital Check as defendant) rather than the number.
2. No contemporaneous press or opinion coverage. No Reuters, Law360, or IPWatchdog item on this specific docket surfaced; the appearance is documented only in aggregated litigation data, not in a court-issued document I could open. That is a thin (though not implausible) evidentiary basis, and the reason the McNabnay/Wyatt rows are marked unverified.

Corroborating pattern (useful context, not proof)

Fish & Richardson appears to be Cedar Lane's default defense firm in the financial-infrastructure wave of this campaign that Digital Check presaged: Excylyn Janaize Hardin-Smith (F&R, New York) has entered appearances for Bank of New York Mellon (S.D.N.Y. No. 1:25-cv-09488), Ingalls & Snyder (No. 1:25-cv-09529), and Oppenheimer & Co. (No. 1:26-cv-00297) (PACER Monitor: BNY Mellon; Ingalls & Snyder; Oppenheimer). That continuity supports F&R as Digital Check's retained defense counsel, even though it does not establish the individual appearances.
