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 writing the overview.

Key docket found. Now let me research the parties, patent ownership history, and any IPR activity.

Now let me verify the patent's status, ownership chain, Coolpad's background, and any IPR history.

Case Overview — Cedar Lane Technologies Inc. v. Coolpad Technologies Inc., No. 1:19-cv-01648 (D. Del.)

The parties. Cedar Lane Technologies Inc. is a Canadian corporation with its principal place of business at 560 Baker Street, Suite 1, Nelson, British Columbia — a small resort town in the B.C. interior that serves as the entity's only listed address (Compl. ¶1, RPX litigation document). It is a classic non-practicing entity: Stanford's NPE Litigation Database categorizes it solely under "acquired patents" (NPE Database profile), and a Chinese (Shenzhen) IP Protection Center risk advisory describes Cedar Lane as "a typical NPE," registered in Canada in 2019, founded by Greg Benoit, an attorney with NPE-litigation experience, holding roughly 193 U.S. patents (191 acquired) of which about 22 remained in force as of late 2022, and having filed over 325 federal patent suits — including against Huawei, MediaTek, Apple and TCL — making it, by that report's Lex Machina-derived count, the most prolific patent plaintiff in the country in 2021 (SZIPRS advisory, Oct. 20, 2022). In this particular case Cedar Lane was represented by George Pazuniak of the Pazuniak Law Office rather than its usual high-volume counsel, Isaac Rabicoff of Rabicoff Law LLC — a distinction worth noting, because Rabicoff's filing practices were separately the subject of a judicial misconduct referral in Cedar Lane v. Blackmagic Design (N.D. Cal. 2020) (referral order reproduced in later N.D. Nev. filing). The defendant, Coolpad Technologies Inc., is a Delaware corporation (registered office c/o Paracorp Inc., Camden, DE) with its U.S. operating address at 10188 Telesis Ct., San Diego, California (Compl. ¶2) — the American arm of Coolpad Group Limited (HKEX: 2369), a Cayman-incorporated, Hong Kong-listed Chinese handset maker based in Shenzhen. Coolpad is an operating company, not a patent plaintiff here: its 2018 annual report describes the United States as having become the group's "core business region," with carrier-channel sales through T-Mobile/MetroPCS dominating, even as group turnover collapsed from HK$7.97bn (2016) to HK$1.28bn (2018) (Coolpad 2018 Annual Report). Cedar Lane sued a financially shrinking, carrier-dependent defendant — a familiar NPE target profile.

The accused technology and the patents. The complaint does not accuse a discrete product line so much as a device family: it refers throughout to the "Exemplary Coolpad Products," and names "at least Coolpad's Illumina" as an accused handset in the '527 count (Compl. ¶21), with infringement pleaded by incorporation of claim charts attached as Exhibits 7–11. The asserted technology is the image-capture data path in a smartphone camera — specifically how pixel data moves from a CMOS imaging array to a mobile applications processor. Cedar Lane's opening salvo was broad: six patents in one complaint (Compl. ¶7), namely U.S. Patent No. 6,473,527 ("Module and method for interfacing analog/digital converting means and JPEG compression means," issued Oct. 29, 2002) — a buffer that feeds A/D-converted image lines to a JPEG codec in the block sizes the codec requires; U.S. Patent No. 6,972,790 ("Host interface for imaging arrays," issued Dec. 6, 2005, filed Dec. 21, 2000) — the case's focus patent, claiming an on-die interface with a FIFO-style memory that stores sensor data at the sensor clock rate, a signal generator that interrupts the host when enough data has accumulated, and a transfer circuit that then reads data out at the processor's rate (asserted claim 1; see the Exhibit 8 chart referenced in Compl. ¶¶37–38); U.S. Patent No. 8,537,242 — the '790 patent's divisional, claiming the same FIFO/counter/interrupt scheme as a method; and three "Virtual reality camera" patents (Nos. 7,292,261; 8,031,223; 7,733,368) covering multi-sensor panoramic/VR camera architectures. The '790 is the patent the case is remembered for, and the one that anchors the existing case summary. Two of the six are, or became, time-limited assets: the '527 patent's term ran from a June 1, 1999 filing and lapsed around June 2019 (just before suit), and the '790 patent's 20-year term from its December 21, 2000 filing would have run to about December 2020 absent patent term adjustment — which I have not verified, but which means the '790 is now almost certainly expired.

Procedural posture and why it matters. Filed September 4, 2019 and assigned to then-District Judge Leonard P. Stark (D. Del.) on September 11, 2019; Coolpad was served September 6, 2019. What followed was pure clock-management: five successive stipulated extensions of Coolpad's answer deadline (to Oct. 27, Nov. 26, Dec. 27, 2019, then Jan. 6 and Jan. 31, 2020), each so ordered by Judge Stark, and then — on January 20, 2020, before any answer, motion to dismiss, or claim construction — Cedar Lane filed a Notice of Voluntary Dismissal as to all defendants (D.I. 10), and the case closed the same day (Justia docket; Unified Patents portal). The docket excerpt I could retrieve does not state whether dismissal was with or without prejudice. Venue choice was not incidental: Delaware is where Coolpad Technologies Inc. is incorporated, so Section 1400(b) venue was unimpeachable post-TC Heartland irrespective of where the accused phones were designed or sold — the reason Delaware became the default forum for NPE suits against Delaware-incorporated U.S. subsidiaries, and why Cedar Lane filed a wave of D. Del. cases in 2019–2022 (e.g., Cedar Lane v. Snap, 1:22-cv-00058-RGA; v. MGM, 1:22-cv-00014-RGA; v. Fantasia Trading, 1:21-cv-01428). The case is notable in three respects. First, it is a textbook illustration of the modern mass-assertion lifecycle: a six-patent complaint with claim charts but no product-specific factual development, four months of stipulated extensions, and a voluntary dismissal that produces no merits ruling, no Markman, and no public record on validity — the cost imposition on the defendant being the point. Second, its outcome is consistent with the broader pattern documented in the Shenzhen advisory, which found Cedar Lane's China-targeted cases resolving almost entirely by settlement, with a median time-to-close of 77 days. Third, and of most analytical interest: I was unable to locate any IPR, PGR, or ex parte reexamination challenging the '790 patent in the sources I searched — so unlike the Parallel-Bio/Unified-style campaigns where defendants pool resources at the PTAB, Coolpad apparently neither petitioned nor joined a petition before the dismissal, leaving the '790's validity untested either in court or at the Board (this is a negative finding from a non-exhaustive search of PTAB dockets and Unified Patents' litigation portal, and should be re-verified against PTAB E2E). The practical consequence is that the '790 exits the scene with a district-court assertion history spanning dozens of defendants and no adjudicated validity or construction ruling to constrain later assertions — while its term winds down.

Sourcing caveats: Party identities, addresses, patents, accused product ("Illumina"), asserted claims, exhibits, and all docket dates above are drawn from the complaint and D. Del. docket as reproduced at the cited Justia/Unified/RPX links and are reliable. Judge assignment (Stark) is from the docket. Founder identity, patent-count and filing-volume statistics come from a Chinese government-affiliated advisory citing Lex Machina — a secondary source I would characterize as indicative rather than authoritative, and the claim that Cedar Lane acquired its portfolio from Intellectual Ventures appears in a Korean IP-office filing and is not something I could independently confirm. The '790 patent's inventor of record is Mark Suska (Canada), per the same Chinese report; I did not verify the assignment chain to Cedar Lane. Coolpad Illumina specifics (carrier, launch date, unit volumes) are not sourced here — the complaint names the device but says nothing about it, and I found no reliable sales data; treat any such detail as unverified.

Key legal developments & outcome

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

I'll research this case systematically, starting with the docket and any reported decisions.

Let me pull the docket details and check for any later Coolpad suits and PTAB activity on the '790 patent.

The 2019 D. Del. case appears to have been dismissed early. Let me verify the complaint contents, check for any later Coolpad suit, and look for PTAB challenges to the '790 patent.

Bottom line

This is a very short, low-substance case. Cedar Lane Techs. Inc. v. Coolpad Techs. Inc., No. 1:19-cv-01648 (D. Del.) was filed 2019-09-04, served 2019-09-06, and voluntarily dismissed by Cedar Lane on 2020-01-20 — before Coolpad ever answered. The docket is 10 entries long and consists of the complaint, the patent report, the summons/service, five stipulated extensions of Coolpad's response deadline, and the notice of dismissal. There is no answer, no counterclaims, no motion practice, no Markman, no discovery, no trial, and no appeal. Everything in the "pre-trial motions / Markman / trial / post-trial" categories you asked about is simply absent, and I'd flag that as the key finding rather than inventing stages.

Chronological developments

1. 2019-09-04 — Complaint filed (D.I. 1).
Cedar Lane Technologies Inc. (a Canadian NPE formed in 2019, principal place of business Nelson, BC) sued Coolpad Technologies Inc. in D. Del., jury demand, § 271 infringement. Filed by George Pazuniak (Delaware counsel), with 12 exhibits and a Patent/Trademark Report (D.I. 3) listing five patents: 6,473,527; 6,972,790; 8,537,242; 7,292,261; 8,031,223. Judge Leonard P. Stark assigned (2019-09-11). No magistrate referral proceeded.

'790 specifics as pleaded. The '790 ("Host interface for imaging arrays," issued 2005-12-06, filed 2000-12-21, inventor Mark Suska, originally Psion Teklogix Systems) was Count 2. Cedar Lane pleaded direct, induced and contributory infringement of "at least exemplary claim 1" by the "Exemplary Coolpad Products," and expressly incorporated the Exhibit 8 claim chart (Compl. ¶¶ 30–39: "Exhibit 8 includes charts comparing the Exemplary '790 Patent Claims to the Exemplary Coolpad Products"). The pleading is the boilerplate form Cedar Lane used across its campaign — no product-by-product technical allegations beyond the chart.

Sourcing caveat: the same complaint text I retrieved also contains a Count 6 labeled the "'368 Patent" (claim 21), which does not match the five patent numbers in the D.I. 3 Patent Report. Either the report or the exhibit/count numbering in the RPX copy is off by one; I could not reconcile this from the free sources, and it does not affect the '790 count.

2. 2019-09-06 — Service; answer due 2019-09-27. (D.I. 4, filed 2019-09-07.)

3. 2019-09-24 → 2020-01-02 — Five successive stipulated extensions of Coolpad's response deadline, each so-ordered by Judge Stark, pushing the deadline from 2019-10-27 → 2019-11-26 → 2019-12-27 → 2020-01-06 → 2020-01-31 (D.I. 5, 6, 7, 8, 9). This pattern — repeated consent extensions with the plaintiff filing the stipulations — is the classic pre-settlement posture in Cedar Lane's docket. No responsive pleading, motion to dismiss, transfer motion, or stay motion was ever filed, so there are no substantive pre-trial rulings to report.

4. 2020-01-20 — Notice of Voluntary Dismissal as to all defendants (D.I. 10); case closed same day. Because Coolpad had not yet served an answer or motion for summary judgment, Cedar Lane could dismiss unilaterally under Rule 41(a)(1)(A)(i) without a court order. The docket does not recite "with prejudice" on its face, and no dismissal order, settlement agreement, or license was filed — terms are undisclosed. Cedar Lane's later conduct in parallel Coolpad-type cases (numerous dismissals within days of service) is consistent with a quick, undisclosed resolution, but I have no source confirming any payment or license in this case.

5. Nothing thereafter. No appeal, no reopened judgment, no fee motion, no Rule 54/damages proceedings. Present posture: terminated (closed 2020-01-20).

Parallel PTAB proceedings

  • No IPR or PGR by Coolpad, and no PTAB proceeding appears anywhere on this docket. Coolpad never appeared, so no petition, stay motion, or estoppel issue arose.
  • I was unable to confirm any IPR/PGR petition against U.S. Patent 6,972,790 in the sources I could reach in this session; my PTAB-specific query was cut off before results returned. I would not assert either that IPRs exist or that none exist without pulling the Patent Trial and Appeal Board's end-to-end review docket for the '790 patent and checking Unified Patents' PTAB database. This is the one item in your list I'd mark as unverified.
  • What is observable is the absence of PTAB deterrence: because Cedar Lane dismissed within ~4.5 months and before an answer, no defendant-side invalidity challenge had a chance to mature in this case. Cedar Lane's model across its campaign was to dismiss early, which structurally suppressed PTAB estoppel and IPR exposure on the '790 and '242 patents.

Why the historical record is thin, and what the real "outcome" is

  • The '790 patent was a mass-assertion asset, not a litigated one. Third-party tracking cited in a 2023 Shenzhen IP Protection Center risk alert lists 226 district-court suits for the '790 patent and 217 for its divisional '242, with an estimated expiration of 2023-08-01 (secondary source; treat the case counts as approximate). Cedar Lane filed 300+ patent suits, was the most frequent patent plaintiff in the U.S. in 2021, and its suits against Shenzhen-based defendants reportedly closed in a median of 77 days, nearly all by settlement. Coolpad fits that template exactly.
  • Subsequent assertions of the same patent (for context on how the '790 was actually used, not part of this case): W.D. Tex./N.D. Tex./D. Del. campaigns against Xerox, OpenEye, Hertz, Avis, Enterprise, SIXT, Vector Security, Brickcom, Grandstream, Voxx, EPIX, Phytech, Excelitas, Alps Alpine, Moxa, and others — see e.g. the Lexology Retail Patent Litigation Reports (Nov. 2022, Feb. 2023, May 2022) and the Alps Alpine complaint, https://storage.courtlistener.com/recap/gov.uscourts.wawd.[317813](/patent/317813)/gov.uscourts.wawd.317813.1.0.pdf. Those cases, in D. Del. and elsewhere, were overwhelmingly dismissed within days to weeks of service (e.g., Cedar Lane v. Phytech, 1:22-cv-00054, dismissed 2022-02-15; Cedar Lane v. Excelitas, 1:22-cv-00011, dismissed 2022-03-29).
  • Enforcement value is now largely spent. With the '790 patent's term expiring 2023-08-01 (per the Shenzhen alert), any remaining exposure is limited to pre-expiration conduct plus the § 286 six-year damages lookback. As of today (2026-11-07) the patent is expired, so no new infringement suits on it can be maintained prospectively.

What to say if a client asks "what happened in Coolpad?"

Nothing happened on the merits. Cedar Lane bought a 2000-vintage CMOS image-sensor interface patent, filed a five-patent, twelve-exhibit boilerplate complaint against a Chinese handset maker's U.S. subsidiary in Delaware in September 2019, granted Coolpad five consent extensions, and walked away with a Rule 41(a)(1) dismissal on 2020-01-20 before Coolpad filed anything. There is no claim construction, no invalidity ruling, no damages figure, and no precedent from this case. Any analysis of the '790 patent's strength has to come from the other Cedar Lane suits or from PTAB; this docket supplies no legal signal at all.

Primary sources used: Justia docket (https://dockets.justia.com/docket/delaware/dedce/1:2019cv01648/69929); Unified Patents docket mirror (https://portal.unifiedpatents.com/litigation/Delaware%20District%20Court/case/1:19-cv-01648); UniCourt docket page; RPX Insight copy of the complaint (https://insight.rpxcorp.com/litigation_documents/13480723); Lexology retail patent litigation reports; Shenzhen IP Protection Center risk alert (Chinese-language, secondary, for portfolio/expiration data). Unverified: any PTAB petition against the '790 patent; the existence or amount of any settlement consideration; the identity of the sixth patent counted in the complaint text.

I'll research this case's docket and counsel records.

Counsel of Record for Plaintiff Cedar Lane Technologies Inc.

Case identified: Cedar Lane Technologies Inc. v. Coolpad Technologies Inc., No. 1:19-cv-01648-LPS (D. Del., filed Sept. 4, 2019; Judge Leonard P. Stark). The complaint asserted five patents (6,473,527; 6,972,790; 8,537,242; 7,292,261; 8,031,223), with the '790 count pleaded in Count 2 and supported by Exhibit 8 — matching the case summary. The case was voluntarily dismissed as to all defendants on Jan. 20, 2020 (D.I. 10).

The single attorney of record

Name Role Firm / Office Note
George Pazuniak (Del. Bar No. 478) Lead counsel and sole attorney of record — signed the complaint, the summons return, all extension stipulations, and the notice of voluntary dismissal O'Kelly & O'Rourke, LLC (formerly O'Kelly, Ernst & Joyce, LLC), 824 N. Market Street, Suite 1001A, Wilmington, DE 19801; direct line listed as (302) 478‑4230 / (207) 359‑8576; gp@del-iplaw.com Delaware patent litigator for 35+ years; Delaware bar since 1976; admitted to the D. Del., Third Circuit, Federal Circuit and Supreme Court; states he has argued 10+ appeals before the Federal Circuit. Frequent Delaware counsel for patent-asserting plaintiffs — e.g., lead trial counsel for Stragent, LLC in Stragent v. BMW / Mercedes-Benz / Volvo (E.D. Tex.) and its related PTAB IPRs; also DDC Technology, LLC v. Mattel and Success LLC v. comma.ai in D. Del.

Important qualifications

  1. No other plaintiff-side counsel appeared. The docket as retrieved (Justia docket for 1:19‑cv‑01648; Unified Patents' Delaware docket portal; UniCourt) lists only George Pazuniak as plaintiff's attorney. No pro hac vice motion, no appearance by additional local or national counsel, and no in-house counsel entry appears on this docket — consistent with the case closing roughly four and a half months after filing, before any Rule 26(f) conference or scheduling order. Compare Cedar Lane's later D. Del. waves (2022–2023), where local-counsel appearances were made by David W. deBruin (Gawthrop Greenwood / deBruin Law, Wilmington & Hockessin, DE) and Raeann Warner (Warner & Scheuerman) — neither appears in the Coolpad matter.

  2. Firm affiliation caveat. Mr. Pazuniak has practiced under more than one shingle in this period (filings in 2019–2023 variously show "O'Kelly & O'Rourke, LLC," "O'Kelly, Ernst & Joyce, LLC," and "Pazuniak Law Office LLC"). I could not retrieve the actual signature block of the Coolpad complaint (D.I. 1) itself; the firm attribution above reflects his affiliation as documented in contemporaneous D. Del. filings and his PTAB pro hac vice declarations, and should be verified against the complaint's signature page on PACER before being cited as a direct quote.

  3. Defendant side. The retrieved docket shows no appearance, answer, or motion by Coolpad before the voluntary dismissal; the extensions of Coolpad's response deadline were obtained by stipulation filed by plaintiff's counsel. I did not find any Coolpad counsel of record for this case.

  4. No sealed material is implicated in this counsel question — the docket entries bearing on counsel (D.I. 1, 4–10) are public.

Sources

If you need certainty on the signature-block firm name and any "of counsel" designations, the next step is a PACER pull of D.I. 1 and the docket's attorney-appearance filter for 1:19-cv-01648.

Defendant representatives

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

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

Bottom line

No attorney ever entered an appearance for Coolpad in this case, and there is therefore no defense counsel of record to identify. The action is Cedar Lane Technologies Inc. v. Coolpad Technologies Inc., No. 1:19‑cv‑01648‑LPS (D. Del.), filed Sept. 4, 2019 (asserting the '790 patent among five patents: '527, '790, '242, '261, '223). Coolpad was served Sept. 6, 2019, but never answered or moved — every response deadline was extended by stipulated order, and Cedar Lane voluntarily dismissed the case on Jan. 20, 2020, before any defense filing. I will not invent names to fill the gap.

Docket evidence for the absence of defense counsel

Docket entry Date Significance
D.I. 1 (Complaint, 12 exhibits incl. Ex. 8 '790 chart) 9/4/2019 Filed by George Pazuniak for Cedar Lane
D.I. 3 (Patent/Trademark Report) 9/4/2019 Lists 6,473,527; 6,972,790; 8,537,242; 7,292,261; 8,031,223
D.I. 4 (Summons returned executed) 9/7/2019 Coolpad served 9/6/2019; answer due 9/27/2019
D.I. 5, 6, 7, 8, 9 (stipulations to extend) 9/24/2019 – 12/31/2019 Each docketed as "filed by Cedar Lane Technologies Inc." — no defense signature block appears in the docket text; the last extension pushed the response date to 1/31/2020
D.I. 10 (Notice of Voluntary Dismissal as to All Defendants) 1/20/2020 Filed by Pazuniak; "CASE CLOSED" entered same day

There is no Rule 7.1 disclosure statement, no notice of appearance, no motion for pro hac vice, no answer, and no motion to dismiss anywhere on the docket. Because dismissal came by notice under Rule 41(a)(1)(A)(i) before Coolpad answered, it was without prejudice as a matter of law — relevant to any later refiling analysis.

Caveat on completeness: the public docket snapshots I could reach (Justia, UniCourt, Unified Patents) are derived from PACER pulls, the most recent being the final Jan. 20, 2020 docket. If Coolpad's counsel appeared only in a sealed filing or an appearance that never made it into those mirrors, I could not see it; nothing in the record suggests one exists, and the pattern of plaintiff-filed stipulations is consistent with counsel negotiating informally without entering an appearance.

Who Coolpad actually uses for patent defense (context — not of record here)

If the practical question is "who do I call for Coolpad," the answer from Coolpad's other patent litigation in this period is Perkins Coie LLP, San Diego office:

  • Thomas N. Millikan — lead counsel / registered practitioner for Coolpad Technologies, Inc. in Coolpad Techs., Inc. v. Bell Northern Research LLC, IPR2019‑01319 and IPR2019‑01320 (Perkins Coie, 11452 El Camino Real, Suite 300, San Diego; Reg. No. 72,316). Routinely Coolpad's PTAB lead.
  • Bing Ai (Reg. No. 43,312) and Yun (Louise) Lu (Reg. No. 72,766) — Perkins Coie San Diego, PTAB counsel on the same Coolpad petitions.
  • James Young Hurt — then Perkins Coie, admitted pro hac vice as backup counsel in IPR2019‑01319 and the attorney who appeared for Coolpad Technologies, Inc. and Yulong Computer Communications at the Jan. 8, 2020 deposition in Bell Northern Research, LLC v. Coolpad Techs., Inc., No. 3:18‑cv‑01783‑CAB‑BLM (S.D. Cal.).
  • On the S.D. Cal. district-court side, notices of appearance for Coolpad/Yulong were filed by Joseph Patrick Reid, John P. Schnurer, and Thomas Nathan Millikan (all Perkins Coie) on 9/14/2018 (D.I. 14–16 in 3:18‑cv‑01783).

These names are offered solely as Coolpad's known patent-litigation counsel of that era; none is counsel of record in D. Del. No. 19‑1648.

Plaintiff's counsel (for completeness)

  • George Pazuniak — plaintiff's Delaware/local counsel of record for Cedar Lane in this case; every filing on the docket carries his signature. He is a well-known Delaware patent litigator (Pazuniak Law Office LLC, Wilmington).
  • Cedar Lane's later campaigns (2022–2023) used different counsel — Isaac Rabicoff (Rabicoff Law LLC) as national counsel and David deBruin / John Phillips as Delaware counsel in the 2023 D. Del. wave — but those appearances postdate and do not touch this case.

Status notes

  1. I found no refiling of Cedar Lane against Coolpad in D. Del. after the 2020 dismissal; the '790 patent's later Cedar Lane assertions (52 cases on record per Patsnap/PAI data) list other defendants (Amlogic, Leica, ZKTeco, Speco, etc.). Treat that as a negative search result rather than a certified absence.
  2. No PTAB petition by Coolpad against the '790 patent appears in my results — Coolpad's IPR activity I could verify was against Bell Northern Research's '554 and '889 patents.
