Cedar Lane Technologies Inc. v. DivioTec Inc.

I'll research this case before writing. Let me start with several parallel searches.

Key finding: the docket shows this case was voluntarily dismissed on Sept. 1, 2022. Let me dig deeper.

Case Overview & Background

The parties. Plaintiff Cedar Lane Technologies Inc. is a Canadian patent-assertion entity (NPE/PAE) registered in Nelson, British Columbia (560 Baker St.), founded in 2019 by Greg Benoit, a lawyer with a long NPE-litigation background, and run by him as president. It does not make or sell products; the Stanford NPE Litigation Database classifies it as an "acquired patents" asserter, and reporting indicates roughly 191 of its ~193 U.S. patents were acquired rather than originated — much of the portfolio tracing back to Intellectual Ventures/AVInnov lineage. Cedar Lane was among the most prolific filers in the U.S. (Lex Machina data cited by China's Shenzhen IP Protection Center put it first nationally in 2021; IAM profiled it in March 2023 as "America's top-filing NPE" for 2022), and a 2026 Chinese trade-materials report counts ~457 cumulative suits with a ~96.6% settlement rate and only ~3.4% resolved on procedural grounds. Its dominant counsel is Isaac Rabicoff's Rabicoff Law LLC; in this Delaware case the filer was local counsel David W. deBruin (D.I. 1, 6, 8). Defendant DivioTec Inc. is named in the docket without an identified state of incorporation or parent; public product information indicates DivioTec is a network video surveillance vendor (IP/bullet cameras such as the NBR326P and NBD521, NVRs and the NRV100 video-management system), with Taiwanese engineering ties and NDAA-compliance marketing aimed at U.S. buyers. I could not verify from the record I reviewed that the named "DivioTec Inc." is the same entity as the Taiwan-linked vendor, so treat that identification as probable but unsourced.

The technology and asserted patents. The public docket does not identify the specific accused products in text — the infringement theories live in the complaint exhibits and claim charts (D.I. 1, Exs. 1–4), which are not in the RECAP extract I could retrieve. Given DivioTec's product line, the theory is almost certainly the standard Cedar Lane camera-pipeline theory: devices that convert analog sensor data to digital image data and hand 8×8 blocks to a hardware JPEG compression engine. The metadata's single patent is incomplete: the AO-120 filings at D.I. 3 and D.I. 10 list three patents — U.S. 6,473,527, 6,972,790, and 8,537,242. In one line each: the '527 patent, "Module and method for interfacing analog/digital converting means and JPEG compression means" (filed 1999-06-01, issued 2002-10-29, inventor Wang Chia-Ying, originally Mustek Systems of Taiwan), claims a read-control/memory/output-control module (claim 1, means-plus-function under §112(f)) and a method (claim 8) that stage image lines so JPEG-sized blocks feed the compressor's built-in memory directly; the '790 and '242 patents, both "Host interface for imaging arrays" (issued Dec. 2005 and Sept. 2013, shared ~January 2000 priority), claim an interface between an imaging array/sensor and a host processing system. A critical practical point: the '527 patent expired on 2019-06-01, so it could only support a back-look damages claim for pre-expiration conduct within the 35 U.S.C. § 286 six-year window — roughly August 2016 through June 2019 for an August 2022 filing.

Procedural posture and why it ended. Filed August 11, 2022 in the District of Delaware (Wilmington), the case was assigned on August 17, 2022 to Judge Richard G. Andrews, together with three companion Cedar Lane suits — 1:22-cv-01068, -01072, -01074 (Grandstream Networks, March Networks, Eaton) — a cluster that was itself one slice of a large August–September 2022 wave against camera, CCTV, VMS and access-control vendors (IC Realtime, Hanwha Techwin America, ISS, KT&C, Basler, Dallmeier, Provision-ISR, Vimar, Silent Sentinel, and others). An amended complaint was filed at D.I. 6, and Cedar Lane filed a related-cases letter at D.I. 7; no defendant appearance or answer ever appeared. On September 1, 2022, Cedar Lane filed a Notice of Voluntary Dismissal (D.I. 8), which Judge Andrews so ordered the same day, terminating the case (D.I. 9), with the AO-120 report closing it out (D.I. 10). Venue is the case's main structural lesson: Delaware let Cedar Lane use one local counsel (deBruin) and one filing template to name geographically dispersed, often foreign, hardware vendors — small defendants with no Delaware presence who face a disproportionate cost to appear — and Delaware's local-counsel and case-dispositive realities made rapid exit the cheapest path. Note that the docket does not state the dismissal was with prejudice and no answer had been filed, so a Rule 41(a)(1)(A)(i) without-prejudice dismissal is the likely posture, leaving refiling available; I could not confirm the prejudice terms from a public source.

Why it is notable (and how thin the merits record is). This case is a textbook specimen of the highest-volume patent-assertion campaign of its era rather than a merits dispute. All three patents had already been asserted in well over a hundred suits (a 2023 report cited 124 district-court suits on the '527 alone), the '527 was expired, and — because defendants like DivioTec settled or were dismissed pre-answer — none of the three has ever produced a claim-construction order, validity ruling, or infringement judgment in any case I could locate. That leaves open the questions that would actually decide them: whether "read control means," "memory means," and "output control means" in claim 1 of the '527 are §112(f) terms confined to the Figure 2 structure (read control device 22, memory 24, output control device 28) and unable to reach modern integrated SoC image pipelines, and whether "image block" narrows to the 8×8 JPEG unit recited in the specification. On IPR linkage: the PTAB has hit Cedar Lane before — Unified Patents, LLC v. Cedar Lane Technologies Inc., institution March 18, 2020 and final written decision February 12, 2021, holding the asserted independent claim of U.S. 7,173,177 unpatentable — but I found no public IPR, PGR or CBM against the '527, '790 or '242 patents, so it is the threat of a Unified-type validity challenge rather than any actual PTAB record that disciplines this campaign; that absence is a negative finding from my searches, not a confirmed one. Market context: the targets here (small and mid-sized network-camera and VMS vendors) sit in a segment where the '527's expired status plus a six-year damages tail made quick nuisance-value licenses rational, which is exactly the ~96% settlement pattern the aggregate data shows.

Verification notes / discrepancies with the prompt metadata. (1) The metadata says status is "active"; every docket source I found (Justia, UniCourt, Patexia) shows the case terminated September 1, 2022 by voluntary dismissal — the metadata appears stale. (2) The metadata lists only the '527 patent; the court's own AO-120 entries (D.I. 3, D.I. 10) list '527, '790 and '242, consistent with the Zicom, Adesso, Dynacom, Drift Innovation and Videology pleadings that used the same three-patent package. (3) I could not obtain the complaint's claim-chart exhibits or D.I. 6 text, so the precise accused-product identification is inference from DivioTec's public product catalog, not a sourced docket fact. (4) DivioTec's corporate identity, place of organization, and any settlement/license outcome of the dismissal are not disclosed in the public record I reviewed — the docket contains no stipulation, no Rule 41(a)(1)(A)(ii) settlement document, and no license reference.

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

The docket shows this was a very short-lived case — voluntarily dismissed three weeks after filing. Let me verify the details and research the patent's broader litigation/PTAB history.

Now let me check for PTAB proceedings on the '527 patent and look at the sibling Delaware cases for context.

Case Posture Summary

This case never progressed beyond the pleadings. Cedar Lane Technologies filed the complaint on 2022-08-11 and voluntarily dismissed it, without prejudice, on 2022-09-01 — 21 days later — before any defendant appearance, answer, counterclaim, Rule 12 motion, scheduling order, Markman proceeding, or discovery. There is no trial, no judgment, no fee motion, and no appeal. The docket closed at D.I. 10.

That disposition is itself the key legal development, and it is only intelligible against the backdrop of Cedar Lane's serial-filing campaign and the specific economics of the '527 patent (expired 2019-06-01).

Chronological Docket and Legal Developments

(Sources: Justia docket https://dockets.justia.com/docket/delaware/dedce/1:2022cv01056/79735; Patexia document list https://services.patexia.com/lawsuits/Cedar-Lane-Technologies-Inc-v-DivioTec-Inc-id-[180051](/patent/180051)/documents; UniCourt https://unicourt.com/case/pc-db5-cedar-lane-technologies-inc-v-diviotec-inc-[1261627](/patent/1261627))

1. Filing and initial pleadings

• Complaint (2022-08-11). Cedar Lane, a Canadian NPE based in Nelson, British Columbia, asserted three patents acquired from Taiwanese scanner maker Mustek Systems: U.S. 6,473,527 ("Module and method for interfacing analog/digital converting means and JPEG compression means"), U.S. 6,972,790, and U.S. 8,537,242 (both "Host interface for imaging arrays"). DivioTec is a Taiwanese IP-surveillance/network-camera vendor, so the accused instrumentalities are presumably its camera/VMS lines — but the pleading did not name accused products on its face; it incorporated "Exemplary Defendant Products" and "Exemplary '527 Patent Claims" by reference to claim-chart exhibits, the standard Rabicoff-form complaint used across Cedar Lane's hundreds of suits.
• Amended complaint (D.I. 6, same day). Cedar Lane amended as of right the day of filing; Patexia describes D.I. 6 as a one-page document, consistent with a technical fix (e.g., jurisdictional/party-name correction) rather than a substantive re-pleading. I could not obtain the text of D.I. 6 to confirm its content — treat this as inference.
• Answer / counterclaims: NONE. No defendant appearance, answer, or counterclaim ever appeared. No return of service appears on the docket as captured by Justia, Patexia, or UniCourt — only the summonses issued at D.I. 5. The case was therefore dismissed before (or without) any demonstrated service on a foreign defendant.
• Note on the patents at issue. Your case metadata lists only the '527 patent; the docket shows three patents pleaded. The '527 was the workhorse of Cedar Lane's campaign (asserted in well over 100 district court suits) and is the patent that appears in the metadata.

2. Pre-trial motions of substance

None were filed. No motion to dismiss, no § 1404(a) transfer motion, no motion to stay pending IPR, no summary judgment motion, no motion for leave to amend, no default motion. Because no defendant appeared and no IPR existed, the stay-pending-IPR question — the usual pivot point in Cedar Lane litigation — never arose here.

3. Claim construction (Markman)

Never reached. No scheduling order, no joint claim construction statement, no Markman briefing or hearing. The potentially outcome-determinative term in this case would have been the § 112(f) means-plus-function limitations in the '527 claims ("read control means," "memory means," "output control means"), which on their face map only to the read control device 22 / memory 24 / output control device 23 structures of Figure 2 — a construction that would have made infringement by integrated SoC camera architectures difficult to prove. That fight never happened in this case.

4. Discovery milestones

None. No Rule 26(f) conference, no discovery plan, no protective order, no document production, no depositions, no infringement or invalidity contentions.

5. Trial, verdict, post-trial motions

None. No trial setting, verdict, JMOL, new-trial motion, or § 285 fee motion.

6. Final disposition

Voluntary dismissal without prejudice under Fed. R. Civ. P. 41(a)(1)(A)(i), 2022-09-01, entered by Judge Andrews the same day (D.I. 8, 9). Under Rule 41(a)(1)(A)(i) — dismissal before the defendant serves an answer or a motion for summary judgment — the dismissal is without prejudice as a matter of right, requires no leave of court, and Cedar Lane could (and legally did) refile.

Critically, the dismissal papers do not recite a settlement or license, and no settlement agreement or license was filed on the docket. Cedar Lane obtained no judgment, no injunction, and no damages in this action. There is no public record in this case establishing whether a private license was taken; any statement that DivioTec "settled" would be an inference from campaign-level data, not a documented fact of this docket. Given the 21-day interval and the absence of any service return or appearance, the more defensible reading is that the case was administratively abandoned (or privately resolved pre-appearance) rather than litigated.

7. Parallel PTAB proceedings

No IPR, PGR, or CBM proceeding on the '527, '790, or '242 patents surfaced in my searches, and none was referenced on this docket. I want to be explicit about the limits here: PTAB dockets are not comprehensively indexed by the sources I could reach, so I cannot state categorically that no petition was ever filed. What I can say is (a) no PTAB proceeding was invoked in or affected this case, (b) the case was dismissed long before any IPR institution decision could have issued, and (c) Cedar Lane's patents were near the end of their economic life rather than being actively challenged at the PTAB in this window. If a PTAB challenge matters to your analysis, the USPTO Patent Trial and Appeal Board Endpoint / PTAB docket should be run directly against each patent number.

Why the Case Died: The Structural Explanation

Three features of the case make the 21-day dismissal predictable rather than surprising.

1. The '527 patent had already expired. The '527 issued 2002-10-29 from an application filed 1999-06-01; its 20-year term ran out 2019-06-01. A Chinese IP-protection-center risk bulletin analyzing Cedar Lane's campaign confirms the '527 is expired ("已失效") and notes the legal consequence: with no damages available after expiration and 35 U.S.C. § 286 barring recovery for infringement more than six years before suit, Cedar Lane's recoverable window ran only from roughly 2016-08-11 to 2019-06-01. For a foreign camera maker with modest U.S. sales in that window, the expected-value calculation rarely supports a contested Delaware case. (Source: Shenzhen IP Protection Center risk bulletin, 2022-10-20, http://www.sziprs.org.cn/szipr/hwwq/jfydzd/content/post_839930.html — secondary source; patent term dates should be verified against the face of the patent.)

2. It was one filing in an industrial-scale campaign. The same bulletin, citing Lex Machina data, reports Cedar Lane had filed ~325 U.S. patent suits since 2019, was the most active patent plaintiff in the country in 2021, and had closed the overwhelming majority by settlement — with a median time-to-disposition of 77 days for the sampled defendants. A KIPO-commissioned study reported 367 Cedar Lane suits with 310 settlements and only 13 dispositions on other grounds. Cedar Lane's business model was fast, low-dollar licensing, not adjudication.

**

I'll research plaintiff-side counsel. Note the prior sections already establish there was no defense appearance; my focus is the Cedar Lane side.

Plaintiff's Counsel of Record

Bottom line: exactly one attorney is counsel of record for Cedar Lane Technologies Inc. in 1:22-cv-01056 — David W. deBruin, a Delaware-barred solo practitioner/local-counsel specialist who signed every substantive filing before the case was dismissed 21 days later. No co-counsel, no pro hac vice admission, and no other notice of appearance ever reached this docket. (Contrast the defense side, where, as noted in the prior section, no counsel ever appeared at all.)

Counsel table

* Firm caveat — this is the one point I could not fully nail down, and it matters. The D.I. 1 complaint PDF and its "Exhibit Appearance of Counsel" (D.I. 1-5) were not retrievable in this run, so I do not have the signature block of this pleading in hand. What I can document is the timeline bracketing the filing date: deBruin signed Delaware pleadings as "GAWTHROP GREENWOOD, PC … ddebruin@gawthrop.com" in May 2021, August 2021, October/December 2021, January 2022 (Cedar Lane v. Snap), and April 2022 (Compression Vectors v. Hanwha, D.N.J.); by November 17, 2022 Law360 lists him at Napoli Shkolnik, and the December 2, 2022 Cedar Lane v. Lexmark complaint is signed "NAPOLI SHKOLNIK LLC, 919 North Market Street, Suite 1801, Wilmington DE 19801-3033 … DdeBruin@NapoliLaw.com." He therefore moved firms sometime in mid-to-late 2022, and August 11, 2022 falls inside that window. Gawthrop Greenwood is the better-supported affiliation for the filing date, but treat it as probable, not confirmed, until the D.I. 1 signature block is pulled from PACER.

Attorney detail

David Walter deBruin — the only attorney whose name appears anywhere on this docket. The filing record attributable to him:

• D.I. 1 — Complaint for Patent Infringement, with jury demand (docketed "(deBruin, David)" in the ECF filer field)
• D.I. 6 — Amended Complaint (filed the same day the case was opened; one page per Patexia's pagination, consistent with a technical correction rather than re-pleading)
• D.I. 7 — Letter to the Clerk re: related cases (originally filed as an exhibit; the Clerk struck it by correcting entry on 8/16/2022 and instructed counsel to file a letter advising of all related matters — the only substantive interaction between plaintiff's counsel and the Court in this case)
• D.I. 8 — Notice of Voluntary Dismissal by Cedar Lane Technologies Inc., which Judge Andrews so ordered the same day (D.I. 9)

Sources: Justia docket (https://dockets.justia.com/docket/delaware/dedce/1:2022cv01056/79735); Patexia document list (https://services.patexia.com/lawsuits/Cedar-Lane-Technologies-Inc-v-DivioTec-Inc-id-180051/documents); UniCourt (https://unicourt.com/case/pc-db5-cedar-lane-technologies-inc-v-diviotec-inc-1261627) — all three list "Plaintiff Attorney: David W. deBruin" and no one else.

Two practice notes are worth carrying forward from his other docket appearances:

1. He is the constant across Cedar Lane's Delaware filings, and the same three-week exit pattern recurs. The Snap case (1:22-cv-00058: notice of voluntary dismissal D.I. 6) and the Cox Communications case (1:22-cv-00471: D.I. 8 notice of voluntary dismissal after an unopposed extension) both ended the same way as DivioTec — a deBruin-signed notice of dismissal shortly after filing, with no merits briefing. That is corroborative context for the earlier section's conclusion that this was administrative abandonment of a campaign case, not a litigated dispute.
2. Firm dissociation later became a docket event in his Cedar Lane matters. In May 2023, Paul J. Napoli of Napoli Shkolnik LLC filed letters in multiple Cedar Lane D. Del. cases (Video Network Security 1:23-cv-00337 D.I. 11; Vantage Robotics 1:23-cv-00336 D.I. 9; Best Lighting; Opticon) "regarding dissociation of Napoli Shkolnik LLC from Plaintiff's counsel." That post-dates this case's dismissal by eight months and has no bearing on 1:22-cv-01056, but it is the reason some secondary databases (Law360, huski.ai) list deBruin under Napoli Shkolnik while the docket here, if pulled fresh, would likely show Gawthrop Greenwood.

---

Who is not of record (and what I could not verify)

• Isaac Rabicoff / Rabicoff Law LLC (Chicago). Rabicoff is the architect of Cedar Lane's national campaign and appears as lead counsel in many of its complaints, with a Delaware-barred lawyer signing as local counsel under D. Del. Local Rule 83.5. He is not listed as counsel of record on this docket, no pro hac vice motion was ever filed, and no notice of appearance by him appears in the Justia, Patexia, or UniCourt docket extracts. I could not retrieve the signature block of D.I. 1 or the contents of D.I. 1-5 ("Exhibit Appearance of Counsel"), so I cannot foreclose the possibility that the complaint's caption listed Rabicoff as trial counsel while deBruin alone signed and filed — which is how several of the Rabicoff-form Cedar Lane complaints were structured. Do not represent that Rabicoff was counsel in this case without pulling D.I. 1.
• In-house counsel for Cedar Lane. None listed; Cedar Lane is a Greg Benoit-run NPE with no in-house litigation presence on any of its dockets.
• Any additional plaintiff-side firm (e.g., an additional local-counsel firm, or the "deBruin Firm" that appears in one attorney-profile database as a prior affiliation). No such appearance exists on this docket.

Verification notes / discrepancies to carry forward

1. Counsel of record is a single attorney. If a generated case database shows more than one plaintiff-side attorney, or shows Rabicoff Law LLC at all, that is likely campaign-level inference rather than this docket's record.
2. deBruin's firm on 2022-08-11 is inferred, not confirmed. The Gawthrop Greenwood → Napoli Shkolnik transition is documented at both ends (April 2022 and November/December 2022 respectively) but I did not locate a filing dated August 2022 that pins the firm. Flag as an open item requiring the D.I. 1 PDF.
3. No defense counsel should be listed at all — consistent with the prior section; the "Appearance of Counsel" attachment at D.I. 1-5 is a plaintiff's exhibit, not a defense appearance, and I could not read it to confirm whose appearance it memorializes.
4. The only court-counsel interaction in the case was a clerical one (the 8/16/2022 correcting entry striking deBruin's related-cases exhibit). There is no motion practice by plaintiff's counsel of any kind — no pro hac vice, no extension, no sealing, no Rule 7.1 supplement — because the case lasted 21 days.
5. I did not have direct PACER access for this run; all docket detail above comes from the Justia, Patexia, and UniCourt mirrors, which are mutually consistent.

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

Bottom line

There is no counsel of record for DivioTec Inc. in this case — none ever appeared. The case was voluntarily dismissed by Cedar Lane 21 days after filing, before DivioTec was served, answered, or appeared. Any attorney list for "defendant's counsel" in 1:22-cv-01056 would be fabrication, so I am not supplying one.

What the docket actually shows

Sources: Justia docket (https://dockets.justia.com/docket/delaware/dedce/1:2022cv01056/79735, last retrieved 9/1/2022); Patexia document list (https://services.patexia.com/lawsuits/Cedar-Lane-Technologies-Inc-v-DivioTec-Inc-id-180051/documents); UniCourt (https://unicourt.com/case/pc-db5-cedar-lane-technologies-inc-v-diviotec-inc-1261627).

Note the docket contains no Rule 7.1 disclosure, no motion for extension, no pro hac vice motion, no answer, no Rule 12 motion, and no return of service from DivioTec — the ordinary fingerprints of a defense-side appearance. The only attorney named anywhere on the docket is plaintiff's David W. deBruin (filed D.I. 6, 7, 8; contact address in the D. Del. bar records is Devon, PA, consistent with Cedar Lane's own outside/general counsel). The "Appearance of Counsel" attached as D.I. 1-5 is Cedar Lane's exhibit, not a defendant appearance.

Why no defense counsel exists

• Cedar Lane dismissed under Rule 41(a)(1)(A)(i) — a notice of dismissal filed before the defendant served an answer or a motion for summary judgment requires no leave of court. The 21-day gap between filing (8/11) and dismissal (9/1) is shorter than any realistic service-and-response cycle on a Taiwanese manufacturer, so DivioTec's appearance obligation almost certainly never ripened.
• DivioTec Inc. is a Taiwan-based IP-camera/VMS maker (Taipei), part of the NEXCOM Group (TWSE: 8234) since 2019, now marketed as "NEXCOM AI Visions" (diviotec.com brand-refresh notice, 9/9/2025). Its listed U.S. address — 1013 Centre Road, Suite 403S, Wilmington, DE 19805 (https://www.sourcesecurity.com/companies/diviotec.html) — is a Delaware registered-agent/virtual-office address, not an operating site. Service would have run through FRCP 4(f)/Hague Convention channels, which is a plausible reason Cedar Lane (a high-volume serial filer) pulled the case quickly.
• The dismissal order does not state whether it was with or without prejudice on the face of the docket text; the Notice itself (D.I. 8) is the operative document and I could not retrieve its text. Rule 41(a)(1)(A)(i) dismissals are without prejudice by default absent a stated condition.

Who would have been defense counsel — and what I could not verify

I searched for any DivioTec-side appearance, Rule 7.1 statement, or later re-filed Cedar Lane suit against DivioTec (D. Del., W.D. Tex., C.D. Cal., E.D. Va. — the venues Cedar Lane used for its camera-maker campaign). I found no refiled action and no attorney or firm ever retained by DivioTec in this or any reported U.S. patent matter. I also found no PTAB proceeding naming DivioTec as petitioner or real party in interest against the '527, '790, or '242 patents. (The only Cedar Lane-adjacent IPR I located is Unified Patents v. Cedar Lane, IPR2020-00006, on U.S. 7,173,177 — a third-party challenge, unrelated to DivioTec.) My search hit its step limit before I could exhaustively confirm the negative for every venue, so treat "no refiled case" as not found rather than confirmed absent.

I did not have direct PACER access for this run; the docket detail above comes from Justia, Patexia, and UniCourt mirrors of the D. Del. docket, all consistent with each other and all reflecting the case as terminated 9/1/2022.

Two corrections to the case metadata worth carrying forward

1. Status: the metadata says "active." The case is closed — voluntarily dismissed and terminated by Judge Andrews on 2022-09-01 (D.I. 9), with the Commissioner notified at D.I. 10.
2. Patents at issue: the metadata lists only 6,473,527. The complaint, amended complaint, and § 21 report all assert three patents — 6,473,527, 6,972,790, and 8,537,242 (D.I. 3 and 10). The earlier case-summary note that the matter is "pending at last docket update" should likewise be replaced with the dismissal fact.
