Cedar Lane Technologies Inc. v. Acer Inc.

I'll research this case thoroughly before drafting.

Case overview

Parties. Cedar Lane Technologies Inc. is a classic non-practicing entity: a British Columbia company incorporated in 2019 (April 29, 2019, per the Shenzhen IP Protection Center's risk alert), founded by Canadian lawyer Greg Benoit, with no products and a portfolio assembled almost entirely by acquisition — most of it carved out of Intellectual Ventures/AVInnov assets. By the time Lex Machina tallied 2021 filings, Cedar Lane was the single most prolific patent plaintiff in the United States, and by 2022 Chinese IP-protection authorities counted roughly 270–325 suits filed, with the vast majority in the Western District of Texas and essentially all prosecuted by Isaac Rabicoff of Chicago's Rabicoff Law LLC (see LexBlog's "NPE Showcase: Cedar Lane Technologies," Oct. 4, 2022; Shenzhen IP Protection Center risk warning, Oct. 20, 2022). Acer Inc. is the Taiwanese parent of the Acer group — a global OEM of notebooks, desktops, monitors, projectors, tablets and related peripherals. Notably, Cedar Lane named the Taiwanese parent, not Acer America Corp., a service/venue choice worth flagging.

Accused technology and asserted patents. The December 13, 2019 complaint (Dkt. 1, with 18 exhibits, i.e., patents plus element-by-element claim charts) pleads direct, induced and contributory infringement against "Exemplary Acer Products" identified in the claim charts, with the inducement/contributory theories framed around Acer selling products and components "to their customers for use in end-user products" (complaint text reproduced at RPX Insight, litigation document 13616488). The patents implicated are a cluster of Polaroid- and Mustek-origin image-capture patents that Cedar Lane acquired and asserted across OEM defendants: U.S. 6,473,527, "Module and method for interfacing analog/digital converting means and JPEG compression means" (Mustek Systems; an interface module that line-buffers A/D image data and feeds JPEG-sized blocks straight to a compression engine, avoiding an extra frame buffer); U.S. 7,292,261, "Virtual reality camera" (capturing successive images, displaying an overlapping portion of the prior image so the user can align the next frame, then stitching a panoramic composite); and U.S. 8,537,242 (and its sibling 6,972,790), "Host interface for imaging arrays" (an interface that buffers imaging-array data and paces transfer to a host processor). A Korean government trade database (KOTRA) summarizing the same docket additionally lists RE44,087 (the reissue of the virtual-reality-camera patent), and 6,972,774 (inserting multiple images into a composite area) — see the KOTRA litigation entry for 1:19-cv-01207. Finnegan's AR/VR litigation update on Cedar Lane v. Corel, 1:20-cv-00352 (W.D. Tex. 2020), describes the same '261/'368/'223/RE44,087 family as panoramic/AR-VR capture patents.

Important correction on the '147 patent

The case metadata assigns U.S. 6,516,147 to this case. Document-level sources do not support that link, and I'd recommend treating it as a record-keeping artifact. The '147 patent — "Scene recognition method and system using brightness and ranging mapping," filed Dec. 19, 2000, issued Apr. 2, 2003, originally Polaroid Corporation (inventor George D. Whiteside), claiming automatic flash/ambient exposure control by comparing a scene brightness map against an infrared range map to identify the subject (see FreePatentsOnline's full text) — appears in Cedar Lane

I'll research this case systematically across dockets, PTAB records, and legal press.

Important discrepancy emerging: the 2019 Acer complaint may not have asserted the '147. Let me pull the actual docket and check.

Let me find the actual complaint exhibits and any later docket activity, plus check PTAB challenges.

Analyst Note — Cedar Lane Techs. Inc. v. Acer Inc., No. 1:19-cv-01207 (W.D. Tex.)

Read this first: the record I can verify is short and ends early. The publicly mirrored docket for this case terminates in February 2020, and I could not retrieve a PACER pull showing the dismissal entry. There is also a probable error in the case metadata regarding the patent. Below I separate (A) what is documented, (B) what is strongly inferable from Cedar Lane's verified campaign pattern, and (C) what remains unsourced and should be confirmed on PACER before publication.

A. Documented chronology

2019-12-13 — Complaint filed (Dkt. 1).
Cedar Lane Technologies Inc. (Canadian NPE, incorporated 2019-04-29 in British Columbia; principal Greg Benoit) sued Acer Inc. in W.D. Tex., Austin Division, assigned to Judge Lee Yeakel. Counsel for plaintiff: Isaac Rabicoff (Rabicoff Law LLC). The complaint carried 18 exhibits plus civil cover sheet — consistent with Cedar Lane's standard practice of attaching the asserted patent plus an infringement claim chart per patent, i.e., roughly nine patents asserted. Filed with a jury demand and a Rule 7.1 corporate disclosure (Dkt. 3); summons issued the same day (Dkt. 7); statutory notice of the patent action sent to the USPTO under 35 U.S.C. § 290 (Dkt. 6).
Source: https://unicourt.com/case/pc-db5-cedar-lane-technologies-inc-v-acer-inc-[280284](/patent/280284)

2020-01-24 — Acer appears and moves for extension (Dkt. 8).
Acer, represented by Eric H. Findlay (Findlay Craft, Tyler, Tex.), filed an unopposed motion to extend its time to answer, move, or otherwise respond.

2020-01-27 — Extension granted (Dkt. 9).
Judge Yeakel ordered Acer's response due 2020-03-16.

2020-02-11 — Last verified docket snapshot.
UniCourt's mirror (last updated 2020-02-11) lists the case as "Pending." No answer, counterclaims, scheduling order, or motion practice appears in any source I retrieved.

No verified activity after 2020-02-11. I found no reported Markman order, summary-judgment ruling, trial, verdict, appeal, or dismissal order for 1:19-cv-01207 in CourtListener, Justia, DocketBird, Patexia, RPX, IPWatchdog's Patent Filings Roundups, or press coverage. This absence is itself consistent with the campaign's documented pattern (see B).

---

B. The patent-identification problem — please correct the metadata

The case summary's linkage of the '147 patent (U.S. 6,516,147, "Scene recognition method and system using brightness and ranging mapping," filed 2000-12-19, issued 2003-02-04) to this case is not supported by the source that actually catalogs the Acer complaint's patents-in-suit.

The Korea IP Protection Agency's litigation database entry for 1:19-cv-01207 records the asserted patents as US RE44,087; 6,473,527; 6,972,774; 7,292,261; and 8,537,242 — the imaging-array/remote-control/panorama cluster — not the '147. That entry also notes Cedar Lane filed a same-day companion suit against ZTE (USA) Inc. asserting the same patents.
Source: https://dream.kotra.or.kr/dream/cms/link/actionLinkBoardDetail.do?SITE_NO=2&MENU_ID=4060&CONTENTS_NO=1&pTmplateCd=NT2319&pDataId=22000000000011838914

The '147 is, separately and verifiably, a Cedar Lane staple — just in other cases:

• TCL Communication, D. Del. 1:20-cv-00836 (filed 2020-06-22) — asserted patents include 6,473,527; 6,516,147; 6,566,805; 6,972,774; 6,972,790.
• Huawei, W.D. Tex. 2:20-cv-00234 — includes 6,516,147.
• ASUSTeK, W.D. Tex. 6:21-cv-01342 (filed 2021) — includes 6,516,147 (per IPWatchdog's filing round-up).
• Lenovo (US), D. Del. 1:22-cv-00051 (filed 2022-01-13; voluntarily dismissed 2022-04-21) — includes 6,516,147.

Recommendation: relabel the patent-at-issue field as "unconfirmed / likely RE44,087, 6,473,527, 6,972,774, 7,292,261, 8,537,242," and treat the '147 as a probable false-positive from the patent's broader family-litigation index.

---

C. Procedural stages that were never reached (as far as the record shows)

---

D. Final disposition — present posture

Most likely disposition: early voluntary dismissal following a nuisance-value settlement, but the specific order is unverified. Two independent data points support this:

1. IAM (2023-03-29) reported that Cedar Lane "has obtained a 96% settlement rate among its terminated cases," with an average case life around 90 days. Source: https://www.iam-media.com/court/us-district-court-for-western-district-of-texas?page=8
2. Cedar Lane's own filings in parallel cases show the identical script — serial agreed extensions of the answer deadline followed by a Notice of Voluntary Dismissal without prejudice (e.g., ASUSTeK, 6:21-cv-01342, Dkt. 13, 2022-06-21, after four agreed extensions; Johnson Controls, 2:25-cv-00815, dismissed 2025-10-17; Lenovo, 1:22-cv-00051, dismissed 2022-04-21).

In this case the extension pattern had already begun (Dkt. 8–9), and the docket goes quiet thereafter. A settled-and-dismissed outcome is the base case; a Rule 41(a) dismissal is the likely vehicle.

Action item: pull the PACER docket sheet for 1:19-cv-01207 (W.D. Tex.) and read every entry after Dkt. 9. The specific entry to look for is a notice/stipulation of dismissal and the accompanying order; that will pin the disposition date and whether dismissal was with or without prejudice. If the case instead shows a Rule 12 motion or a transfer motion by Findlay Craft, this memo's "never reached" conclusions need revision.

---

E. Parallel PTAB proceedings

• No IPR, PGR, or CBM on U.S. 6,516,147 was identified in my searches — unsurprising, since the '147 does not appear to have been asserted against Acer here, and Cedar Lane's asserted claims generally expired or neared expiry (the '147's term ran from a 2000 filing).
• The one documented PTAB/reexam attack on the Cedar Lane portfolio was brought by Unified Patents, LLC in October 2019 against a single Cedar Lane patent, and it succeeded. I could not confirm which patent number that was, so I am not attributing it to any patent here. Source (secondary, Chinese-language enforcement alert): https://gdoip.com/friction/158.html
• Effect on this litigation: none identifiable. No stay motion, no IPR-driven claim narrowing, and no adverse validity ruling appears in the Acer docket.

---

F. Context worth flagging in any write-up

• Counsel risk was a live issue. In 2020, Judge Vince Chhabria (N.D. Cal.) sanctioned Cedar Lane and Rabicoff for "positions in his filings that were objectively frivolous … and did so in bad faith," noted Rabicoff was "a serial filer of patent lawsuits in the Northern District of California [but] is not admitted to practice in this district," and referred him to that district's Standing Committee on Professional Conduct. Source: Seyfarth Shaw NPE Showcase, https://www.jdsupra.com/legalnews/npe-showcase-cedar-lane-technologies-1171526/
• Forum economics. This 2019 suit predates the migration of Cedar Lane's Waco-volume docket to Judge Alan Albright; in 2021–22 Cedar Lane's filings concentrated before Albright, with roughly 23% of all U.S. patent cases that year. Source: IAM, supra.
• Scale. Cedar Lane is the top patent plaintiff by filing volume in multiple years (Lex Machina 2022 report; Patexia's 2025 report credits it with 409 cases and 109 patents). Acer is one of hundreds of defendants, which is why no merits ruling exists.

---

Sourcing caveats

• Party names, court, case number, and filing date are taken from the docket mirror and are reliable.
• The patents-in-suit for this specific case are the weakest link in the current summary; the KOTRA record contradicts the '147 attribution and should be reconciled against the complaint's own Exhibit 1–18 list (available via PACER Dkt. 1).
• Dismissal date, prejudice status, and any settlement terms are unknown — I found no source for them and have not guessed.
• The Unified Patents October 2019 PTAB challenge is documented only in secondary reporting and its target patent is unspecified.

I'll research the counsel of record for Cedar Lane Technologies in this case.

Let me pull the actual docket sheet and confirm the patents asserted.

Important finding: the complaint's counts don't match the '147 patent. Let me verify the complaint signature block and counsel details.

Bottom line

Only one attorney has appeared for Cedar Lane Technologies in this case: Isaac Phillip Rabicoff of Rabicoff Law LLC — and he appeared as both filer and sole counsel of record. He is a well-known patent monetization/"serial filer" attorney whose practice is essentially a Cedar Lane captive docket.

A threshold caveat first, because it affects the whole analysis: the retrieved docket excerpt does not corroborate the '147 patent link in the case metadata, and the complaint's own text points elsewhere (see §5).

---

1. Verified counsel of record for Plaintiff Cedar Lane Technologies Inc.

One-line experience note: Rabicoff is the architect of Cedar Lane's mass-assertion campaign — the firm has appeared for Cedar Lane in dozens of suits (a 2023 Shenzhen IP Protection Center analysis counted 58 Cedar Lane cases handled by Rabicoff Law LLC), and Cedar Lane itself was the most frequent patent plaintiff in the U.S. in 2021, with 300+ total filings. He also represents other NPEs (e.g., Payvox LLC in NFC cases against Mastercard, Samsung, Motorola).

---

2. Docket support, entry by entry

From the UniCourt mirror of the W.D. Tex. docket (case assigned to Judge Lee Yeakel, San Antonio/Austin docket, 1:19-cv-01207):

• 12/13/2019 — D.E. 1: COMPLAINT for patent infringement, filing fee $400, receipt 0542-12963634, filed by Cedar Lane, with 18 exhibits plus a civil cover sheet; signature block is Rabicoff.
• 12/13/2019 — D.E. 2: "NOTICE of Attorney Appearance by Isaac Rabicoff on behalf of Cedar Lane Technologies Inc."
• 12/13/2019 — D.E. 3: Rule 7.1 Disclosure Statement by Cedar Lane (Rabicoff).
• 12/13/2019 — D.E. 4: Request for Issuance of Summons (Rabicoff).
• 12/13/2019 — D.E. 5: JS-44 Civil Cover Sheet (Rabicoff).
• 12/13/2019 — D.E. 6–7: Report on Patent to USPTO; Summons issued as to Acer Inc.
• 1/24/2020 — D.E. 8: Acer's unopposed motion for extension of time (by Eric H. Findlay of Findlay Craft P.C., Tyler, TX — the defense-side analog to note for context, styled as Acer's counsel, not Cedar Lane's).
• 1/27/2020 — D.E. 9: Order granting extension; Acer answer due 3/16/2020.

UniCourt's party-attorney summary for the case lists exactly one Plaintiff Attorney: Isaac Rabicoff, and one Defendant Attorney (Findlay).

---

3. What is explicitly absent — stated, not inferred

• No local counsel appeared. Unlike many W.D. Tex. patent cases, the docket excerpt shows no separate Texas-local firm for Cedar Lane. Rabicoff appears to have proceeded as a sole practitioner of record.
• No pro hac vice motion appears in the retrieved entries. (This matters: Rabicoff's later N.D. Cal. and S.D.N.Y. filings are routinely accompanied by PHV motions — e.g., S.D.N.Y. D.E. 6 in Cedar Lane v. Ingalls & Snyder, 1:25-cv-09529 — indicating he is not generally barred in those districts. Nothing in the W.D. Tex. excerpt shows a comparable motion, which suggests he relied on a general W.D. Tex. admission, but I cannot confirm that from the record I retrieved.)
• No in-house counsel for Cedar Lane appeared; Cedar Lane is a Canadian NPE (principal place of business per the complaint: 560 Baker Street, Suite 1, Nelson, BC V1L 4H9, Canada) with no in-house litigation staff on the docket.
• No other Rabicoff Law attorneys (e.g., no second signatory) appear in the retrieved entries.
• Docket coverage is incomplete. The public excerpt I retrieved ends at D.E. 9 (1/27/2020), with the case status shown as "Pending – Other Pending." Any post-February-2020 substitution of counsel, addition of local counsel, or transfer would not be captured here.

---

4. Attorney profile — Isaac Phillip Rabicoff

• Firm: Rabicoff Law LLC (f/k/a Rabicoff & Rabicoff, P.C.), a two-office boutique; the Alexandria, VA address appears on 2021 W.D. Tex. filings (Cedar Lane v. Pantum, No. 6:21-cv-00424-ADA, D.E. signed 11/8/2021), while current dockets list Chicago, IL.
• Role at Cedar Lane: Outside litigation counsel of record in the overwhelming majority of Cedar Lane's U.S. suits across W.D. Tex., D. Del., E.D. Tex., D.N.J., S.D.N.Y., E.D.N.Y., C.D. Cal., and W.D. Wash.
• Notable/relevant experience:
  • Cedar Lane's '527/'790/'242 and '261/'774/'87 imaging-array and JPEG-interface families (the same families at issue here) — filed in well over 100 cases, characteristically resolved by voluntary dismissal or consent judgment within 40–160 days, i.e., a high-volume, fast-settlement licensing model rather than contested litigation.
  • Other NPE clients include Payvox LLC (NFC/contactless payment patents against Mastercard, Samsung, Motorola, Nokia, HMD, Sony, Visa).
  • Adverse reputation point worth flagging: In 2020, Judge Vince Chhabria (N.D. Cal.) sanctioned Cedar Lane and Rabicoff, finding filings "objectively frivolous" and made in bad faith, and referred Rabicoff to the district's Standing Committee on Professional Conduct; the order noted he "is a serial filer of patent lawsuits in the Northern District of California [but] is not admitted to practice in this district." Source: secondary — Law Street Media "NPE Showcase – Cedar Lane Technologies" (Oct. 4, 2022), summarizing the sanction order. I did not retrieve the underlying N.D. Cal. order or its citation, so treat the specific quote and date as needing primary-source confirmation.

---

5. Correction needed to the case metadata (patent identification)

This is a substantive flag rather than a counsel issue, but it should be fixed in the case file:

The '147 patent (U.S. 6,516,147) does not appear to be asserted in this case. The complaint as retrieved asserts five different patents:

• U.S. 6,473,527 ("Module and method for interfacing analog/digital converting means and JPEG compression means")
• U.S. 8,537,242 ("Host interface for imaging arrays")
• U.S. 7,292,261
• U.S. 6,972,774
• U.S. RE44,087

Sources: the Acer complaint text itself (RPX Insight litigation document 13616488 — Counts 1–5 and the prayer for relief enumerate the '527, '242, '261, '774, and '87 patents against "Exemplary Acer Products"); and the Korea IP Protection Agency's KOTRA dispute database entry for 1:19-cv-01207, which lists the asserted rights as USRE44087 | US6473527 | US6972774 | US7292261 | US8537242 — a match on four of five. Note that the standardized Delaware AO-120 filings for the sibling Cedar Lane cases list "6,473,527; 6,972,790; 8,537,242," i.e., a slightly different three-patent mix, reflecting Cedar Lane's practice of recombining families case by case.

Recommendation: treat 6,516,147 as unconfirmed and probably an artifact of the family-litigation record. Verify with the D.E. 1 complaint's "Patents-in-Suit" paragraph and the D.E. 6 Report on Patent (Form AO-120), which is filed with the USPTO and would list the patents definitively. I was unable to retrieve D.E. 6 itself.

---

6. Confidence and verification gaps

To close the gaps, pull a current PACER docket report for 1:19-cv-01207 (W.D. Tex.), plus D.E. 1 and D.E. 6, and confirm via the docket's "Attorneys" tab whether any notice of substitution, local-counsel appearance, or pro hac vice order was entered after January 2020.

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

Found a strong lead — Eric H. Findlay filed the extension motion for Acer. Let me dig into the full docket and his firm.

Now let me pull the full docket to see all counsel appearances.

Bottom line

Only one attorney is confirmed on the docket as counsel of record for Acer Inc. in No. 1:19-cv-01207: Eric H. Findlay of Findlay Craft, P.C. (Tyler, Texas). He is the sole attorney whose name appears on any Acer filing in the docket data I can retrieve, and he appears to have acted in the local-counsel role that Findlay Craft routinely fills in Texas patent cases. I found no record of national/lead counsel, pro hac vice sponsors, or Acer in-house counsel appearing in this specific case.

Confirmed counsel of record — Defendant Acer Inc.

Docket grounding for Findlay:

• Dkt. #8, Unopposed MOTION for Extension of Time to File Answer re #1 Complaint (filed Jan. 24, 2020), signed by "(Findlay, Eric)" and docketed as a motion "by Acer Inc." — https://unicourt.com/case/pc-db5-cedar-lane-technologies-inc-v-acer-inc-280284
• Dkt. #9, Order granting #8, Acer's answer due March 16, 2020, signed by Judge Lee Yeakel (entered Jan. 27, 2020).
• The same aggregator's party/attorney table lists the "Defendant Attorney" as Eric H. Findlay and the sole plaintiff attorney as Isaac Rabicoff (Rabicoff Law LLC), confirming Findlay was the only defense-side name of record in the captured docket.

Firm sources: https://www.findlaycraft.com/ · https://profiles.superlawyers.com/texas/tyler/lawyer/eric-h-findlay/a1dcdeb8-f3c4-430c-944e-9396095be74a.html · https://thenationaltriallawyers.org/members/eric-findlay/ (bio describing him as doing more than "local counsel" in Texas patent matters)

What I could not confirm — treat as open, not as fact

1. No later appearances are verified. The docket snapshot I can access ends with the January 27, 2020 extension order. I could not retrieve Dkt. #10 onward, so I cannot rule out that national counsel (or Acer in-house counsel) later appeared by notice or pro hac vice motion. Nothing in the record I retrieved supports naming any additional attorney, so I have not named one. To close this gap, pull the full PACER docket for 1:19-cv-01207 (W.D. Tex., Austin Division) and check for notices of appearance, pro hac vice motions, and any Rule 7 disclosure statement filed by Acer.
2. No answer or dismissal entry verified. I found no docket entry for Acer's answer (which was due 3/16/2020) or a dismissal. A trade-press report (Mondaq, Oct. 26, 2020) states that "[t]he oldest open case in this campaign, filed against Acer in December 2019, is actually stayed pending dismissal in light of a settlement" — https://www.mondaq.com/unitedstates/patent/[998106](/patent/998106). That is a secondary source; I could not verify the stay or dismissal order on the docket. If a dismissal with prejudice was entered, the practical significance of the counsel roster is largely historical.
3. No evidence of a lead/national firm. I specifically checked whether Alston & Bird or TechKnowledge Law Group (firms that have represented Acer in other litigations, e.g., the Philips C.D. Cal. matter) appeared here; I found no such appearance in this case and am not attributing them to it.

Flag on the case metadata: the patent list looks wrong

This bears on the accuracy of the file: the Korean IP Protection Agency's litigation database entry for exactly this case number (1:19-cv-01207, Cedar Lane v. Acer, W.D. Tex., filed 2019-12-13) lists the asserted patents as US RE44,087; 6,473,527; 6,972,774; 7,292,261; and 8,537,242 — five patents, matching the eighteen exhibits attached to the complaint (Dkt. #1). U.S. Patent No. 6,516,147 does not appear in that list. Source: https://dream.kotra.or.kr/dream/cms/link/actionBoardDetail.do?SITE_NO=2&MENU_ID=4060&CONTENTS_NO=1&pTmplateCd=NT2319&pDataId=22000000000011838914&pUntyDsetId=GD0231&gbn=Out

Cedar Lane did assert 6,473,527 against later Acer-adjacent defendants and elsewhere, which may explain how a cross-reference to this campaign got attached to the '147 record. Recommendation: before relying on "patents at issue: 6,516,147" for this case, confirm against the complaint (Dkt. #1) itself; the metadata's own note that the link is "probable but not confirmed" is, in my view, likely wrong rather than merely unconfirmed.
