Summary

N.D. Cal. action before Judge William H. Orrick by XR Communications/Vivato against Ruckus. The complaint attached exhibits for the '296, '728, and '231 patents; the court entered a final judgment of indefiniteness as to the '231 patent claims, which was later given collateral-estoppel effect.

XR Communications (Vivato) v. Ruckus Wireless, N.D. Cal. No. 3:18-cv-01992 (WHO)

Bottom line: The case never reached trial. It ended on a stipulated final judgment of invalidity entered 2021-10-15, after Judge Orrick granted summary-style relief through claim construction: the term "search receiver logic" in the '231 patent was held to be a means-plus-function term with no corresponding structure in the specification, rendering claims 1–9 and 12 indefinite. The Federal Circuit affirmed on 2023-05-18, rehearing en banc was denied 2023-07-24, and that judgment was then used offensively as collateral estoppel to knock out the same '231 claims against ten other Wi-Fi vendors in the C.D. Cal. litigation.

1. Filing and initial pleadings

  • 2018-04-02 — Complaint filed in N.D. Cal. asserting three patents against Ruckus Wireless: U.S. Patent Nos. 7,062,296 ('296), 7,729,728 ('728) and 6,611,231 ('231), with the patents attached as Exhibits A–C. Case assigned to Judge William H. Orrick, III (Magistrate Judge Donna M. Ryu). See docket index at https://unicourt.com/case/pc-db1-xr-communications-llc-v-ruckus-wireless-inc-[717078](/patent/717078).
  • 2018-04-25 — Ruckus answer and affirmative defenses, with a jury demand, and a corporate-interest disclosure identifying ARRIS International plc and ARRIS US Holdings as parents (Ruckus was by then an ARRIS subsidiary). Id.
  • 2018-05-08 / 2018-05-30 — Companion case related and consolidated for pretrial purposes. XR's parallel suit against Arris Solutions, Inc., N.D. Cal. No. 3:18-cv-02736 (originally before Judge Jeffrey S. White), was found related and reassigned to Judge Orrick. The two cases thereafter moved together and were appealed together (Fed. Cir. Nos. 22-1125 and 22-1141).
  • Pleadings were amended at least twice: the docket reflects an answer directed to a Second Amended Complaint (Dkt. 96), which is consistent with XR narrowing the case as PTAB decisions came down (see below). I could not independently verify the filing date of the SAC from the sources retrieved — treat that detail as unconfirmed.

2. Parallel PTAB proceedings (this is the main driver of the litigation's shape)

XR's three patents drew nine IPR petitions in early-to-mid 2018, filed by Aruba, Cisco, and a Ruckus/ARRIS/Netgear/Belkin group. XR's own mandatory notices catalog them: https://ptacts.uspto.gov/ptacts/public-informations/petitions/[1511735](/patent/1511735)/download-documents.

Strategic effect: The Ruckus IPR against the '231 patent was denied institution, which meant no PTAB estoppel shield and no § 315 stay leverage for Ruckus on that patent — the '231 infringement case therefore had to be litigated in district court. Conversely, XR's '296 claims were wiped out at the Board in October 2019, which is the

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

I'll research the counsel of record for XR Communications/Vivato in this case.

Let me pull the specific docket sheet for this case.

Counsel of Record for Plaintiff XR Communications, LLC d/b/a Vivato Technologies

Short answer: Plaintiff was represented throughout by a single firm — Russ August & Kabat LLP (RAK), Los Angeles — appearing directly in N.D. Cal. (no separate local-counsel firm, no in-house counsel appearing). The team was led by Marc A. Fenster and Reza Mirzaie, who filed the complaint and handled the case through claim construction, final judgment, and the Federal Circuit appeal.

Attorney roster (3:18-cv-01992-WHO)

Attorney Role Firm / Office Note on patent-litigation experience

Fenster (CA SBN 181067) Lead counsel / trial counsel, partner Russ August & Kabat, 12424 Wilshire Blvd., 12th Fl., Los Angeles, CA 90025 Co-chair of RAK's plaintiff-side patent litigation practice; argued this case's appeal at the Federal Circuit (XR Commc'ns v.

E-filed Dkt. 1 (Complaint, with Exs. A–C = the '296, '728, '231 patents), Dkt. 5–7, and Dkt. 137–138; his declaration (Dkt. 176-1) supplied the intrinsic-record exhibits for the Markman briefing decided at Dkt. 191. Second-chaired Core Wireless v. Apple (N.D. Cal. 2016) and Core Wireless v. LG; Realtime Data v. Riverbed.
Philip X.

James N. Pickens (CA SBN 307474) Associate Russ August & Kabat (Los Angeles) Signed the notice of appeal in this case; also on the Federal Circuit briefs in 22-1125/22-1141.
Kent N. Shum Attorney (partner) Russ August & Kabat (Los Angeles) Listed as plaintiff's counsel on the PACER-derived docket for this case; visible on the related Vivato matters (e.g., signing plaintiff filings in XR Commc'ns v. Ruckus Wireless, C.D. Cal. No. 2:17-cv-02961, and XR Commc'ns v. D-Link, C.D. Cal. No. 8:17-cv-00596).
Brian D. Ledahl (CA SBN 186579) Appellate counsel only — not on the district-court record Russ August & Kabat (Los Angeles) Appears in the Federal Circuit appearance line for 22-1125/22-1141; do not treat him as district-court counsel of record here.

Verification / sourcing notes

  • The plaintiff-side roster above matches the PACER-derived docket aggregations (UniCourt docket for 3:18-cv-01992 lists plaintiff attorneys as Fenster, Conkle, Pickens, Shum, Chan, Wang, Mirzaie) and the signature blocks on filed documents in this case (Complaint Dkt. 1; Notice of Appeal, Nov. 2, 2021, listing Fenster, Mirzaie, Wang, Conkle, Chan, Pickens as "Attorneys for Plaintiff XR Communications, LLC dba Vivato Technologies").
  • Caution on aggregated dockets: UniCourt's party-attorney list for this case mixes both sides. Richard L. Seabolt (Duane Morris, San Francisco) and Korula T. Cherian are defense counsel — Seabolt filed Dkt. 133/134 substituting in for Audra Thompson as Ruckus's counsel of record, and Cherian signed Ruckus's venue/transfer papers in the earlier C.D. Cal. action. Similarly Matthew S. Yungwirth, Alice E. Snedeker, Amadou Diaw, Don Livornese, and Ronald Wielkopolski are Ruckus/Arris-side (Duane Morris). None represent the plaintiff.
  • Local counsel: none of record. RAK is a Los Angeles firm whose attorneys are California-barred, so no pro hac vice admission or N.D. Cal. local-counsel firm was required; RAK appeared directly before Judge Orrick.
  • In-house counsel: none appeared on the docket. XR Communications/Vivato is a licensing entity with no in-house litigation appearance in this case.
  • Sealed material: the docket contains sealing motions and redacted filings (e.g., the parties' joint claim-construction materials and damages-related briefing), but nothing suggesting a concealed appearance; counsel of record is fully reflected in the public docket.

Procedural anchors for the representation

  • Dkt. 1 (Apr. 2, 2018): Complaint filed by Reza Mirzaie, attaching the '296, '728, and '231 patents.
  • Dkt. 191 (Sept. 1, 2021): Claim Construction Order construing "search receiver logic" as § 112 ¶ 6 means-plus-function with no adequate corresponding structure — 2021 WL 3918136.
  • Dkt. 193–194 (Oct. 15, 2021): Stipulation of Final Judgment and Judgment of invalidity/indefiniteness.
  • Nov. 2, 2021: Notice of Appeal signed by the RAK team; appeals docketed as Fed. Cir. 22-1125 (Arris) and 22-1141 (Ruckus).
  • May 18, 2023: Fed. Cir. affirmed (nonprecedential, XR Commc'ns, LLC v. Arris Solutions, Inc.); panel rehearing/rehearing en banc denied July 24, 2023 — the affirmance that later supplied the collateral-estoppel footing for the indefiniteness judgment on the '231 patent.

Caveat: I could not pull the ECF docket directly from PACER (paywalled); the docket entries and signature blocks above are drawn from PACER-derived aggregators (UniCourt, RPX Insight document images) and reproduced court opinions. If you need the formal ECF "Attorney to be Noticed" list with each attorney's add date, that requires a PACER docket-report pull.

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

I'll research the docket and related sources for defense counsel of record.

I have a lead: Duane Morris as defense firm. Let me verify individual attorneys, roles, and docket appearances.

Let me pull the actual docket and verify each attorney's appearance, plus check for later substitutions.

Counsel of record for the defendant — XR Communications v. Ruckus Wireless, N.D. Cal. No. 3:18-cv-01992 (WHO)

Bottom line: Ruckus Wireless, Inc. was represented throughout by Duane Morris LLP, in a split staffing model typical of that firm's Ruckus practice: an Atlanta-based patent trial team as lead, with a San Francisco partner serving as N.D. Cal. local counsel, and Duane Morris's Washington, D.C. office handling the parallel PTAB work. No other firm appears for Ruckus on the district court docket. Because the case resolved by stipulated judgment after claim construction rather than trial, "lead trial counsel" below describes role, not an actual trial appearance.

Attorneys appearing of record for Ruckus Wireless, Inc.

Attorney Role Firm / office Notes
Matthew S. Yungwirth Lead counsel (defense) Duane Morris LLP — Atlanta, GA (1075 Peachtree St. NE) Duane Morris partner and Ruckus's long-time outside patent counsel; lead counsel for Ruckus in Chrimar Systems v. Ruckus Wireless, N.D. Cal. No. 3:16-cv-00186, and in the related Chrimar IPRs (IPR2017-00718/-00719/-00720/-00790); argued/appeared for Ruckus and Netgear as appellees in the Chrimar Federal Circuit appeal; listed as Ruckus's Duane Morris counsel on the Fed. Cir. appeal in this case (No. 22-1141). Admitted pro hac vice in N.D. Cal.
Richard L. Seabolt Local counsel of record (N.D. Cal.) Duane Morris LLP — San Francisco (One Market Plaza, Spear Tower, Suite 2200); CA SBN 67469 Long-time Duane Morris litigator and the firm's standard Northern District local counsel for Cisco, Sonus and other tech clients (e.g., EON Corp. IP Holdings v. Sensus, Affinity Labs v. Nike). Entered his appearance on 2018-04-24 (Dkt. 133) and filed the substitution that withdrew Audra Thompson as counsel of record (Dkt. 134). Caveat: public bar-association reporting indicates Seabolt was appointed to the Alameda County Superior Court in 2018 (he had been a Duane Morris partner since 2006), so he very likely withdrew after appointment; I could not retrieve the post-2020 docket to confirm the withdrawal date or his successor as local counsel.
Alice E. Snedeker Associate / case team; carried the appeal Duane Morris LLP — Atlanta, GA Appears in the docket-derived defendant-attorney list for 3:18-cv-01992 and is identified as Duane Morris counsel for Ruckus on the Federal Circuit appeal (Nos. 22-1125/22-1141).
Audra Lynn Thompson Of record for Ruckus, later withdrawn Duane Morris LLP (per docket-derived listing) Withdrawn by the substitution at Dkt. 134 (Seabolt). In the parallel C.D. Cal. litigation she appears as counsel tied to ARRIS, which is consistent with her being ARRIS/CommScope-side counsel rather than a Duane Morris associate — I could not verify this affiliation directly, so treat it as an inference.
Amadou K. Diaw Of record (role not specified in retrievable entries) Listed as a defendant-side attorney on the 3:18-cv-01992 docket roll (firm affiliation not independently confirmed) Name appears in the consolidated defendant-attorney list for this case; I found no separate filing or firm biography confirming his role. Flagged as unverified.
Don Francis Livornese Defense attorney in the pre-transfer C.D. Cal. phase Firm affiliation not verified Appears as defendants' counsel for XR v. Ruckus (C.D. Cal. No. CV 17-02961) at the 2017-10-02 C.D. Cal. hearing before Judge Guilford, i.e., before the case was transferred to N.D. Cal. in March 2018. Included in the N.D. Cal. defendant-attorney roll as well.
Korula T. Cherian Defense attorney in the pre-transfer C.D. Cal. phase (venue/transfer motion practice) Firm affiliation not verified Filed Ruckus's motion to dismiss or transfer for improper venue in C.D. Cal. (Dkt. 24 line of filings, Oct. 2017) and related venue-discovery papers — the motion that produced Judge Guilford's March 20, 2018 transfer order to N.D. Cal.
Ronald R. Wielkopolski Listed as a defendant-side attorney on the case roll Firm affiliation not verified No filing or firm biography located confirming role; flagged as unverified.

Related counsel worth separating out (same firm, different forum)

  • John Baird (Duane Morris) — lead counsel on the IPR petitions filed 2018-05-03 by Ruckus, ARRIS Solutions, ARRIS Enterprises, Netgear and Belkin against the '231, '296 and '728 patents (IPR2018-01016/-01017/-01018). These were PTAB appearances, not district court appearances of record in 3:18-cv-01992. See XR's mandatory notices identifying Baird as petitioners' lead counsel: https://ptacts.uspto.gov/pt
