Case Overview — Avago Technologies General IP (Singapore) Pte. Ltd. v. Acer Inc., No. 3:15-cv-05427-EMC (N.D. Cal.)

Parties and procedural posture. Plaintiff Avago Technologies General IP (Singapore) Pte. Ltd. is the Singapore-incorporated patent-holding subsidiary of Avago Technologies Ltd., the semiconductor company spun out of Agilent/HP in 2005 (and, after the 2016 Broadcom acquisition, the predecessor of Broadcom Inc.). It is best characterized as an operating company's IP-holding and licensing arm rather than a classic litigation-only PAE: it does not itself make products, but it holds and monetizes a portfolio derived from real R&D operations — here, the former LSI Logic/Agere/Lucent portfolio that Avago acquired with LSI Corporation in 2014 (the '087 patent's inventor, Kwok Kit Chau, was an LSI Logic engineer). Defendants were Acer Inc. (Taipei, Taiwan) and its U.S. distribution subsidiary Acer America Corp. The complaint was filed November 25, 2015 and docketed in the San Jose division before Magistrate Judge Laurel Beeler as No. 5:15-cv-05427, then reassigned as a related case to Judge Edward M. Chen in the San Francisco division (Courtroom 5, 17th Floor) as No. 3:15-cv-05427-EMC, alongside Avago's other portfolio suits (LSI Corp. v. Funai Elec. Co., No. 3:15-cv-04307-EMC, and Avago v. ASUSTeK Computer, No. 3:15-cv-04525-EMC). Avago was represented by Kilpatrick Townsend & Stockton (David E. Sipiora, Kristopher L. Reed, Matthew C. Holohan, Robert J. Artuz); Acer by TechKnowledge Law Group (Craig Kaufman). See docket sheet, https://dockets.justia.com/docket/california/candce/5:2015cv05427/[293234](/patent/293234); Dkt. 24 (Jan. 22, 2016 stipulation).

The patent and the accused technology. Only one patent was asserted here: U.S. Patent No. 5,870,087, "MPEG Decoder System and Method Having a Unified Memory for Transport Decode and System Controller Functions" (filed Nov. 13, 1996; issued Feb. 9, 1999). In one line: it claims an MPEG-2 decoder architecture in which a single memory is shared by three otherwise separate blocks — the transport logic that demultiplexes the encoded stream, the MPEG video decoder, and the system controller that runs the device — instead of dedicating separate buffers to each function. Claim 1 (the only independent claim at issue in the PTAB) recites a channel receiver, transport logic, a system controller, an MPEG decoder, and "a memory coupled to the MPEG decoder" storing code and data usable by all three. The theory in this wave of cases was that commodity MPEG-2 video decoder/system-on-chip silicon (supplied by third parties such as MediaTek or Realtek) embedded in Acer notebooks, tablets and displays practiced that unified-memory architecture, making the OEM a direct and indirect infringer. Caveat on sourcing: the Acer complaint itself (Dkt. 1) is not reproduced in the public databases I could access, so I could not verify the specific accused Acer model numbers; the analogous ASUS complaint in the same campaign accused, e.g., model GS751JM on the '087 patent, and the parallel letter rogatory in the ASUS case sought MediaTek component discovery, but I have not confirmed Acer's specific accused SKUs. The docket's cause-of-action field showing "15 U.S.C. § 1126" is a CM/ECF docketing artifact, not the real theory.

Outcome and why the case matters. The case never reached the merits. The parties stipulated on January 22, 2016 to a First Amended Complaint schedule (Dkt. 24), the case was referred to mediation on January 5, 2016 (Dkt. 21), and on February 9, 2016 the parties disclosed that they had "executed a Settlement and Patent License Agreement … effective January 1, 2016 that the parties believe will resolve this matter," projecting dismissal by March 18, 2016 (Dkt. 28). Judge Chen signed an order of dismissal on March 15, 2016 (Dkt. 30). No claim construction, infringement or validity ruling issued, and the license terms are confidential. Its significance is contextual: it is a clean specimen of the 2015–2017 Avago/LSI consumer-electronics licensing campaign — sue a global OEM in Avago's home Northern District of California forum, then convert the suit into a portfolio license within weeks. Venue mattered: Avago's parallel ASUS case had been filed in E.D. Tex. in February 2015 and transferred to N.D. Cal. in September 2015, and this case was filed directly in N.D. Cal. (Avago's San Jose headquarters), reflecting the period's forum dynamics just before TC Heartland. The case is also directly linked to the PTAB wave over the same patent: ASUSTeK/ASUS filed IPR2016-00646 on the '087 patent on February 22, 2016 — one month after Acer's FAC stipulation — which was instituted on August 22, 2016 on claims 1, 5, 7–11 and 16, and the institution decision expressly identified this Acer case as a co-pending district-court proceeding asserting the '087 patent (https://www.docketalarm.com/cases/PTAB/IPR2016-00646/.../Decision_Granting_Institution.pdf). That IPR was terminated on May 16, 2017 after settlement, per Unified Patents' docket (https://portal.unifiedpatents.com/ptab/case/IPR2016-00646), so the patent's validity was never adjudicated against Acer either. Additional petitions followed (Sony's IPR2017-00520, noticed January 20, 2017; another filed July 18, 2017 as IPR2017-01816), and the '087 patent was later redeployed by Broadcom against Sony (C.D. Cal. 2016, PlayStation 4) and Amazon — illustrating how a single 1990s LSI Logic MPEG decoder patent became a recurring portfolio-licensing lever across three corporate owners. I have not independently verified the Final Written Decision outcomes of the later Sony/other petitions, so I do not assert them here.

Key legal developments & outcome

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

Avago Techs. Gen. IP (Singapore) Pte. Ltd. v. Acer Inc., No. 3:15-cv-05427-EMC (N.D. Cal.)

Bottom line: This was an extremely short-lived case — roughly 3½ months from complaint to dismissal. It was one offshoot of Avago/LSI's late-2015 campaign asserting the '087 MPEG-decoder patent against PC/consumer-electronics OEMs, and it was resolved by a private patent-license agreement before any defendant even answered, before any claim construction, and before the PTAB instituted the parallel IPR. There is no Markman ruling, no summary-judgment ruling, no trial, no verdict, and no appeal in this docket.

1. Filing and initial pleadings

  • 2015-11-25 — Complaint filed. Avago Technologies General IP (Singapore) Pte. Ltd. sued Acer Inc. and Acer America Corp. in N.D. Cal. (San Francisco), Case No. 3:15-cv-05427, assigned to Judge Edward M. Chen (Magistrate Judge Laurel Beeler also listed). Nature of suit: patent; jury demand by plaintiff. Sole patent at issue on the case record: U.S. Patent No. 5,870,087, "MPEG Decoder System and Method Having a Unified Memory for Transport Decode and System Controller Functions" (inventor Kwok Kit Chau; issued 1999-02-09; originally an LSI/Lucent-lineage asset acquired by Avago in the 2014 LSI acquisition). Docket: https://dockets.justia.com/docket/california/candce/5:2015cv05427/293234
  • The complaint was part of a coordinated wave: Avago asserted the same '087 patent against ASUSTeK (No. 3:15-cv-04525, originally filed in E.D. Tex. as 2:15-cv-00239 and transferred to N.D. Cal.; later 3:16-cv-00451), and, after the Broadcom acquisition, against Sony (Broadcom Corp. v. Sony Corp., 8:16-cv-01052, C.D. Cal.), Amazon, and others. Avago's own mandatory notices in the PTAB confirm the Acer filing date and case number. (See Avago's 37 C.F.R. § 42.8 notices in IPR2017-00520: https://ptacts.uspto.gov/ptacts/public-informations/petitions/[1478054](/patent/1478054)/download-documents?artifactId=fJ7_qLUK4BrF2Xe-a6b0ddPrFeWqitjRR09J56PxVikExGS3ajtXsVU)
  • No answer and no counterclaims were ever filed in this docket. As of the 2015-12-08 administrative stipulation, "Defendants in Case No. 15-cv-05427-EMC have not yet appeared." (Stipulation filed in the related LSI/Avago actions: https://cases.justia.com/federal/district-courts/california/candce/3:2015cv04307/[291325/103](https://assignmentcenter.uspto.gov/search/patent/reelFrameDetail?reelFrame=291325-0103)/0.pdf)
  • 2015-12-10 — Dkt. 13: Stipulated order resetting the CMC from 2016-01-14 to 2016-01-05 (joint CMC with the related Avago/LSI cases).
  • 2015-12-23 — Dkt. 14/15: Stipulated order on Acer's response date and the CMC — granted in part; CMC left at 2016-01-05.
  • 2015-12-30 — Dkt. 18: Stipulation to allow all counsel to appear by telephone at the 2016-01-05 CMC — denied.
  • 2016-01-05 — Dkt. 20/21: The parties filed a stipulation selecting mediation, which the Court signed as an order referring the case to mediation. This is the first docket signal that the parties were on a settlement track rather than a litigation track.
  • 2016-01-20/22 — Dkt. 23/24: Stipulation and order permitting Avago to file a First Amended Complaint by 2016-02-16, with Acer's answer/response due 2016-03-16; Acer consented and accepted electronic service. No FAC appears on the available docket before the case was dismissed, so no amended pleading became operative. (https://docs.justia.com/cases/federal/district-courts/california/candce/3:2015cv05427/293234/24)

2. Pre-trial motions of substance

None. There was no Rule 12(b) motion to dismiss, no § 1404(a) transfer motion, no motion to stay pending IPR, and no summary-judgment motion in this docket. (The transfer fight in this wave occurred in the ASUSTeK case, which was transferred from E.D. Tex. to N.D. Cal.; Acer was sued directly in N.D. Cal., so no transfer motion was needed.)

3. Claim construction (Markman)

Never reached. The case was dismissed months before any Joint Claim Construction Statement was due. For context only, claim construction on the '087 patent claims ("unified memory," "circuit" limitations, etc.) proceeded in the ASUSTeK and Broadcom v. Sony matters — e.g., the C.D. Cal. claim construction order at D.I. 150 in 8:16-cv-01052 is cited as an exhibit in later PTAB petitions. Nothing about that construction is attributable to, or binding in, the Acer case.

4. Discovery milestones

None of strategic significance. No infringement contentions, no document production orders, no discovery motions appear on the docket. The parties' mediation referral (2016-01-05) preceded any contention or discovery deadlines.

5. Trial, verdict, post-trial motions

None. No trial date was ever set; no JMOL, new-trial, or fee motion was filed.

6. Final disposition

  • 2016-02-09/11 — Dkt. 26/28: Stipulation and order extending all deadlines sixty days, reciting that the parties had executed a Settlement and Patent License Agreement effective 2016-01-01, that they believed it "will resolve this matter," and that they anticipated "seeking dismissal of this action under the terms of the Agreement on or before March 18, 2016." The CMC was reset to 2016-04-21 and the Rule 26(f) report deadline to 2016-04-14. (https://cases.justia.com/federal/district-courts/california/candce/3:2015cv05427/293234/28/0.pdf)
  • 2016-03-15 — Dkt. 30: ORDER OF DISMISSAL, Judge Edward M. Chen. This is the terminal docket entry; the case is closed. The publicly available docket text of Dkt. 30 does not, in the versions I could access, recite whether dismissal was with or without prejudice or whether the Court retained jurisdiction to enforce the settlement; given the recitation in Dkt. 28, it was plainly a dismissal pursuant to the parties' Settlement and Patent License Agreement, entered three days ahead of the parties' stated 2016-03-18 target.
  • No appeal. Avago did not appeal (there was nothing to appeal), and the Federal Circuit has no Acer-side '087 appeal.

Present posture: Closed since 2016-03-15. Acer/Acer America are out of the '087 dispute as licensees under the 2016-01-01 agreement.

7. Parallel PTAB proceedings on the '087 patent, and their effect here

Plaintiff representatives

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

Bottom line

The plaintiff's side in Avago Techs. Gen. IP (Singapore) Pte. Ltd. v. Acer Inc., No. 3:15-cv-05427-EMC (N.D. Cal.) was handled by a single firm — Kilpatrick Townsend & Stockton LLP — with a Denver-based patent litigation team and a San Francisco attorney serving as the local/California-facing counsel. Four attorneys signed the plaintiff's filings of record. I found no in-house Avago/Broadcom attorney appearing on the docket, and no pro hac vice motions (consistent with all four being California-barred). The case was short-lived: the parties signed a settlement and patent license agreement effective January 1, 2016, and the case was dismissed on March 15, 2016 (Dkt. 30), so the appearance record is thin — roughly 30 docket entries total.

Plaintiff's counsel of record

Attorney Role Firm / office Note on experience
David E. Sipiora (Cal. SBN 124951) Lead counsel of record; the signature attorney on every plaintiff filing in this case Kilpatrick Townsend & Stockton LLP, 1400 Wewatta St., Suite 600, Denver, CO Kilpatrick Townsend partner and the lead Avago-side attorney across the co-pending N.D. Cal. Avago/LSI patent campaign involving the '087 patent (e.g., Avago v. ASUSTeK, No. 3:15-cv-04525); signed as "Attorneys for Plaintiff Avago" on Dkts. 23, 24, 28.
Kristopher L. Reed (Cal. SBN 235518) Core team member on the district-court filings; named "Lead Counsel" for Avago as Patent Owner in the parallel PTAB proceeding on the same patent Kilpatrick Townsend & Stockton LLP, Denver, CO Listed on the plaintiff's signature blocks here (Dkts. 24, 28) and designated lead counsel for Avago in ASUSTeK v. Avago, IPR2016-00646 (U.S. Pat. No. 5,870,087) — the IPR attacking the same patent at issue against Acer.
Matthew C. Holohan (Cal. SBN 239040) Team member / of-record counsel on the plaintiff's filings Kilpatrick Townsend & Stockton LLP, Denver, CO Listed in the plaintiff's signature block (Dkts. 24, 28). I could not independently verify his individual case history beyond his appearance here; treat his specific experience as unsourced.
Robert J. Artuz (Cal. SBN 227789) Local / California counsel of record (San Francisco office address used for service and California practice) Kilpatrick Townsend & Stockton LLP, Two Embarcadero Center, 8th Floor, San Francisco, CA Listed in the plaintiff's signature block (Dkts. 24, 28) as the San Francisco-office contact for Avago. Individual case history not independently verified.

Sourcing

Caveats / what is not established

  • No PACER docket sheet was directly retrieved. The above is reconstructed from the Justia/RECAP document images and docket index; the docket is small (complaint, stipulations, dismissal), so the risk of a missing counsel entry is low but not zero. If a sealed or unindexed appearance exists, I did not see it — and I found no sealing order in the available record.
  • No in-house counsel appears of record. Avago's in-house legal department (then part of Avago/Broadcom) did not file an appearance in this case in anything I could locate; the settlement and license were negotiated by the parties, but no in-house signature appears on the docketed papers.
  • No pro hac vice admissions. All four listed attorneys carry California bar numbers, including the Denver-based ones, so no PHV applications were needed — which is also why the appearance list is so short.
  • Individual bios for Holohan and Artuz were not confirmed through firm pages or reported decisions; I have deliberately not characterized their prior matters.
  • For context only (not plaintiff's counsel): Acer was represented by Craig Kaufman of TechKnowledge Law Group LLP (Dkt. 28), and the same '087 patent was later challenged at the PTAB by ASUSTeK (IPR2016-00646), Sony (IPR2017-00520), and Amazon (IPR2017-00963/-00964/-01816), with Kilpatrick Townsend continuing as Avago's Patent Owner counsel.

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 appearances for this case.

Good initial leads. Let me pull the docket detail and confirm Acer's counsel.

Now let me pin down the specific appearances filed in this docket.

Counsel of Record for Defendants — Avago Techs. Gen. IP (Singapore) Pte. Ltd. v. Acer Inc., No. 3:15-cv-05427-EMC (N.D. Cal.)

Bottom line up front: The defendants are Acer Inc. and Acer America Corp. (together, "Acer"), and they were represented throughout by TechKnowledge Law Group LLP, a boutique IP-litigation firm that serves as Acer's outside patent litigation counsel. Craig R. Kaufman is the attorney confirmed of record in this docket. The firm's Acer team in this period also included Michael C. ("Chaocha") Ting, Kaiwen ("Kai") Tseng, and Hsiang ("James") H. Lin, though I could not retrieve this case's docket sheet in full and therefore cannot confirm which of them formally entered an appearance here (see caveats below).

Confirmed of record

Attorney Role Firm / office Note
Craig R. Kaufman (Cal. Bar No. 159458) Lead counsel / outside trial counsel; the only defense attorney whose signature I can confirm on a filing in this docket TechKnowledge Law Group LLP — 100 Marine Parkway, Suite 200, Redwood Shores (Redwood City), CA 94065 (the firm used a San Francisco, 1521 Diamond St. address earlier, and a Cupertino address by the 2020s) Longtime outside patent counsel to Acer. Signed both Acer stipulations here: the Jan. 20, 2016 stipulation re first amended complaint (Dkt. 23, so ordered Dkt. 24) and the Feb. 9, 2016 stipulation extending all deadlines pending settlement (Dkt. 28). Also represented Acer in the Federal Circuit (No. 2015-1125), Koninklijke Philips v. Acer (D. Del., later N.D. Cal. No. 4:18-cv-01885), the Optical Disk Drive antitrust MDL (N.D. Cal. No. 3:10-md-02143), and more recently Atlas Global Techs. v. Acer (E.D. Tex. 2023) and Acer's 2025 SEP suits against PACCAR.

Cir. No. 2015-1125 (July 17, 2015) listing "CRAIG R. KAUFMAN, TechKnowledge Law Group LLP, Redwood City, CA, for defendants-appellees Acer, Inc., Acer America Corporation" (https://cases.justia.com/federal/appellate-courts/cafc/15-1125/15-1125-2015-07-17.pdf).

Attorneys on the TechKnowledge Acer team — appearance in this docket not verified

Attorney Role Firm / office Note
Michael C. ("Chaocha") Ting Co-counsel (appeared alongside Kaufman for Acer in the Federal Circuit) TechKnowledge Law Group LLP, Redwood City/Redwood Shores, CA Listed by the Federal Circuit as additional Acer counsel in No. 2015-1125; the firm's later Acer dockets (e.g., Mimzi LLC v. Acer, D. Del. 1:19-cv-00272) record that he left TechKnowledge around November 2019. His notice of appearance in 15-cv-05427 is plausible but unverified.
Kaiwen ("Kai") Tseng (Cal. Bar No. 193756) Co-counsel / pro hac vice appearances on Acer's behalf in various districts TechKnowledge Law Group LLP, Redwood Shores → Cupertino, CA Recurring Acer representative in patent cases (Philips v. Acer No. 4:18-cv-01885; NTT v. Acer, W.D. Tex.; Atlas Global v. Acer, E.D. Tex. 2023; Acer v. PACCAR, E.D. Tex. 2025). Signed Acer pleadings alongside Kaufman and Lin.
Hsiang ("James") H. Lin (Cal. Bar No. 241472) Co-counsel TechKnowledge Law Group LLP, Redwood Shores, CA Signed Acer filings with Kaufman/Tseng in the Philips v. Acer and Optical Disk Drive matters; part of the same Acer account team.

Important procedural context and caveats

  • No answer, no Markman, no trial. The parties executed a Settlement and Patent License Agreement effective January 1, 2016. On Feb. 9, 2016 they stipulated to extend all deadlines by 60 days and told Judge Chen they "anticipate[d] seeking dismissal of this action under the terms of the Agreement on or before March 18, 2016" (Dkt. 28; further CMC reset to April 21, 2016). Because the case resolved within roughly four months of filing, the defense-side appearance record is thin — no substantive motion practice by Acer appears in the materials I could retrieve.
  • Appearances were late. A Dec. 8, 2015 joint stipulation in the companion Avago cases states that "Defendants in Case No. 15-cv-05427-EMC have not yet appeared" (https://cases.justia.com/federal/district-courts/california/candce/3:2015cv04307/[291325/103](https://assignmentcenter.uspto.gov/search/patent/reelFrameDetail?reelFrame=291325-0103)/0.pdf). So no defense attorney was of record during the first two weeks after the Nov. 25, 2015 filing.
  • Caveat on completeness. I was not able to pull the full PACER/CourtListener docket sheet (No. 293234) or the notices of appearance and pro hac vice orders. I therefore cannot confirm whether Tseng, Lin, or Ting filed formal appearances in this case, and I cannot rule out that an Acer in-house lawyer was listed on a corporate disclosure statement or Rule 26(f) report. Nothing I found indicates any filing in this case was sealed; the sealing activity I identified was in the later Philips v. Acer matter, not here.
  • No local counsel identified. TechKnowledge (Redwood Shores) is itself a Bay Area firm, so Acer apparently proceeded without separate N.D. Cal. local counsel.
  • For completeness, plaintiff Avago was represented by Kilpatrick Townsend & Stockton LLP — David E. Sipiora, Kristopher L. Reed, and Matthew C. Holohan (Denver, CO; 415 telephone prefix) — as shown on the same stipulations.

If you need the exact appearance docket entries, the next step would be a direct PACER pull of D.I. 1–30 in 3:15-cv-05427-EMC; I'd rather flag that gap than guess at filing numbers.
