XR Communications, LLC d/b/a Vivato Technologies v. NETGEAR, Inc.

I'll research this case thoroughly before drafting the overview.

Let me dig deeper into the docket, the IPR, and the patents.

Case Overview — XR Communications, LLC d/b/a Vivato Technologies v. NETGEAR, Inc., No. 2:21-cv-04942 (C.D. Cal.)

Parties and what they do. XR Communications, LLC is a Delaware LLC with its principal place of business in Venice, California, and does business as "Vivato Technologies." Its complaints describe a lineage from Vivato, Inc., a 2000-vintage, $80M+ venture-backed Wi-Fi/beamforming startup whose engineering roster allegedly included Siavash Alamouti, Ken Biba, Vahid Tarokh and others, and which claims 400+ deployments of beamforming phased-array base stations before pivoting to patent monetization (complaint ¶¶10–16, XR v. Cisco, W.D. Tex. No. 6:21-cv-00623). In practice XR is treated by defense-side and litigation-tracking sources as a non-practicing patent assertion entity holding a legacy Vivato portfolio of 17+ patents; RPX/Mondaq describe it as "of uncertain management" that "claims now to be doing business as 'Vivato'" (Mondaq, Aug. 2021). It is represented by Russ, August & Kabat (Reza Mirzaie, Marc Fenster, Philip Wang, Minna Chan, James Pickens, Christian Conkle). NETGEAR, Inc. is the publicly traded consumer/SMB networking vendor whose Orbi, Nighthawk and ProSAFE access points and routers are the accused instrumentalities.

The accused technology. The theory is standard-driven, not product-specific. XR alleges that NETGEAR's Wi-Fi access points and routers implementing MU-MIMO under IEEE 802.11ac infringe because the AP assigns clients to 802.11ac "group IDs"/user positions and computes steering from "VHT Compressed Beamforming Feedback" frames — i.e., that the standardized beamforming/beam-steering machinery reads on claims written years earlier to proprietary smart-antenna control. XR pleads both direct and induced infringement (installation/use per NETGEAR's documentation) and willfulness based on notice at filing. The campaign's assertion grid covers "access points, routers, and controllers" and, for NETGEAR specifically, product sets featuring "Smart WiFi," "Auto-Radio Management," or "automatic channel allocation" (Mondaq).

Patents asserted. RPX records three patents-in-suit in this docket (RPX Insight); the PTO § 290 filing for the companion NETGEAR docket (8:21-cv-01064) lists the same three (AO 120):

• U.S. 10,594,376 — "Directed Wireless Communication" (issued Mar. 17, 2020; App. No. 15/486,245 filed Apr. 12, 2017 as a Track

I'll research this case systematically, starting with the docket and PTAB proceedings.

Initial findings are significant — this case was consolidated into a 2017 lead case. Let me dig deeper.

Let me pin down the district court docket specifics and the dismissal of NETGEAR.

XR Communications v. NETGEAR, 2:21-cv-04942 (C.D. Cal.) — Litigation Timeline and Outcome

Threshold point on the case's structure

Case No. 2:21-cv-04942 had an unusually short independent life: it was filed June 16, 2021 and administratively closed 12 days later on June 28, 2021, when Judge David O. Carter consolidated it into the long-running 2017 lead case, XR Communications, LLC v. D-Link Systems, Inc., No. 8:17-cv-00596-DOC-JDEx. Every substantive development affecting NETGEAR after that date occurred in the lead case, in the PTAB, or in the Federal Circuit — not in 2:21-cv-04942 itself. Any analysis of the "outcome" of 2:21-cv-04942 that stops at its own docket will be misleading.

A second wrinkle worth flagging: the docket and PTAB records list a companion NETGEAR complaint filed the same day, XR Communications v. NETGEAR, No. 8:21-cv-01064-DOC-JDEx (filed 2021-06-16 in the Santa Ana/Southern Division, originally assigned to Judge James V. Selna), which was consolidated into 8:17-cv-00596 by the same June 28, 2021 order. The two NETGEAR suits were pleaded on the same campaign patents; the record I reviewed does not explain why XR split them across two divisions, so I treat that as an open question rather than assume a purpose.

---

1. Filing and initial pleadings

Patents asserted. The campaign complaints against NETGEAR pleaded three patents: the '728 patent (7,729,728), the '376 patent (10,594,376), and the '939 patent (8,289,939) — all directed to MU-MIMO/beamforming and asserted against Wi-Fi 6 (802.11ax) and 802.11ac access points and routers (long product lists including Nighthawk RAX/RXE series, Orbi RBK/RBS, and WAX access points). Your case metadata lists only the '376; the '376 was the patent that drove the PTAB proceedings discussed below.

Answer and counterclaims. No answer or counterclaim by NETGEAR appears on the 2:21-cv-04942 docket. NETGEAR's response deadline (2021-07-13) post-dated the June 28 closure, so any responsive pleading would have been filed in the lead case 8:17-cv-00596. I was unable to verify a NETGEAR answer/counterclaim in the lead case from the sources retrieved; the lead-case docket shows amended answers and counterclaims by co-defendant Aruba Networks LLC (2022), but I will not attribute a NETGEAR pleading I could not confirm. Treat the answer/counterclaim element as unverified rather than absent.

---

2. Pre-trial motions of substance

a) Consolidation (granted, 2021-06-28). The single most consequential "motion" in this case was the related-case/consolidation maneuver. By rolling the 2021 NETGEAR suits into the 2017 D-Link lead case before NETGEAR answered, XR ensured that NETGEAR's case would be governed by a claim construction record and a stay posture already being built in a five-year-old consolidated action before Judge Carter.

b) Stay pending IPR (granted). Following the Board's October 20, 2022 institution decision in IPR2022-00613, the district court in 8:17-cv-00596 stayed the consolidated proceedings. This is stated in XR's own PTAB filing ("In light of the Board's decision to institute inter partes review of the '376 patent, the district court in XR Communications, LLC v. D-Link Systems, No. 8:17-cv-00596 (C.D. Cal.) stayed its proceedings"). I could not retrieve the stay order's docket number or exact date; the statement establishes the fact of the stay and its October 2022 trigger, not its precise date.

c) Summary judgment / collateral estoppel (granted in part as to other patents). In the lead case, Judge Carter granted-in-part D-Link's collateral-estoppel motion holding claims 3–5 and 12 of the '728 patent barred because they were materially the same as claims 5–7 of parent '296 patent, which the PTAB had cancelled. XR Commc'ns, LLC v. D-Link Sys., Inc., No. 8:17-cv-00596, ECF No. 313 (C.D. Cal. Apr. 18, 2022). XR argued the differing burdens (preponderance at the PTAB vs. clear and convincing in court); the court accepted the argument as to some claims only. This did not touch the '376.

d) No motion to dismiss or transfer of substance on the merits in 2:21-cv-04942 is reflected on the docket I reviewed — the case was closed before Rule 12 practice could develop.

3. Claim construction (Markman)

The Markman work occurred in the consolidated lead case, not in 2:21-cv-04942:

• Special Master Report and Recommendation on Claim Construction, XR Commc'ns LLC v. D-Link Sys., No. 8:17-cv-00596-DOC-JDE, Dkt. 280 (Jan. 27, 2022).
• Order Adopting Special Master's Report and Recommendations re Claim Construction, Dkt. 312 (Apr. 18, 2022).
• Parallel construction of the same family in W.D. Tex.: Markman hearing 2022-09-01 and Claim Construction Order, XR Commc'ns LLC v. Cisco Sys., No. 6:21-cv-00623-ADA, Dkt. 56 (Sept. 30, 2022).

Caveat I want to be explicit about: I could not verify from the retrieved record whether the Special Master's January 2022 R&R expressly construed terms of the '376 patent (as opposed to the '728/'939/'231 patents then being litigated), nor the specific constructions adopted. The '376 was asserted in the 2021 complaints and entered the consolidated case in mid-2021, but the R&R's subject matter is not established by the sources I have. Any description of a "Markman outcome for the '376" in this case would be reconstruction, not verified fact. What is verified is the procedural fact of the R&R and adoption, and the subsequent stay.

Lessons from the related constructions are nonetheless strategically relevant: in the N.D. Cal. Arris case the court construed "search receiver logic" in the '231 patent as a means-plus-function term lacking adequate disclosed structure, rendering claims indefinite — a construction XR lost and could not distinguish.

---

4. Discovery milestones of strategic significance

Discovery in the consolidated case had already been underway since 2017 (the lead case carries the "DISCOVERY" and "PROTORD" flags and a protective order). The milestones that actually mattered to NETGEAR were:

• 2021-12-20 — XR's preliminary infringement contentions in the campaign (as reflected in parallel W.D. Tex. cases), pinning the '376 case to the 802.11ax/ac sounding protocol and "steering matrix"/beamforming limitations.
• 2022-01-30 — Deposition of petitioners' expert Dr. Zhi Ding in the IPR track, which became a key exhibit in the '376 IPR record.
• The N.D. Cal./C.D. Cal. indefiniteness record on the '231 (Arris) which, via collateral estoppel, ended part of the consolidated case.
• Fact discovery on the '376 against NETGEAR was effectively never completed, because the case was stayed in October 2022 and settled in September

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

Let me pull the actual docket and confirm counsel appearances.

Bottom line

Counsel of record for XR Communications, LLC d/b/a Vivato Technologies in No. 2:21-cv-04942 were exclusively lawyers from Russ August & Kabat (RAK), Los Angeles — a single-firm team, with RAK simultaneously acting as lead counsel and local counsel (it is C.D. Cal.–based). Note an important structural fact: this docket no longer has any "current" counsel of record. On 6/28/2021 Judge Carter entered an order consolidating LA CV 21-04942 into the low-numbered lead case, SA CV 17-00596-DOC (JDEx), administratively closed 21-04942, and directed that "[a]ny party/counsel not listed on the low numbered case shall file a Notice of Appearance in that case" (Dkt. 21). So the operative appearances after June 2021 are in 8:17-cv-00596.

Plaintiff's counsel

Related team members in the consolidated lead case (not shown as 21-04942 counsel): Brian D. Ledahl (RAK, CA SBN 186579) is identified in the Federal Circuit's May 18, 2023 opinion as part of Vivato's appellate team, and RAK's signature blocks in the consolidated proceedings also list Neil A. Rubin, Paul A. Kroeger, Amy E. Hayden, Shani Williams, Kristopher R. Davis, Kent N. Shum, Jonathan Ma, and Matthew D. Aichele (RAK's Washington, DC office).

Not counsel: Kai Hansen signed Vivato's PTAB powers of attorney as "Manager, XR Communications, LLC" — a client representative, not an attorney of record. I found no in-house attorney appearing for XR on this docket.

Sourcing and caveats

• Docket entries confirming the above: Dkt. 1 (Complaint, filed 6/16/2021, signed by Reza Mirzaie — "Attorney Reza Mirzaie added to party XR Communications, LLC"); Dkt. 18 (Amended Notice of Related Cases, signed Mirzaie); Dkt. 19 (6/23/2021 transfer order to Judge Carter/Judge Early); Dkt. 20 (6/25/2021 proof of service, signed Mirzaie); Dkt. 21 (6/28/2021 consolidation order). Docket text via UniCourt and Justia's C.D. Cal. docket index: https://unicourt.com/case/pc-db5-xr-communications-llc-v-netgear-inc-[935436](/patent/935436) and https://insight.rpxcorp.com/litigation/cacdce-[823692](/patent/823692)-xr-communications-v-netgear (RPX shows the case filed 6/16/2021, closed 6/28/2021, 13 days in litigation).
• Caveat on role labels: The six-name plaintiff roster (Fenster, Mirzaie, Wang, Chan, Pickens, Conkle) comes from the aggregated docket/attorney listing for 21-04942. I could verify Mirzaie's signature on the complaint and multiple filings directly; I could not independently pull a separate Notice of Appearance for Fenster, Chan, Wang, Pickens, or Conkle in this short-lived docket. Treat their "of record" status as reliable but their precise role characterization (lead vs. supporting) as my inference from RAK's filings in the related Vivato matters and the Federal Circuit opinion. Nothing on this docket appears sealed; the case was simply closed by consolidation before any substantive motion practice.
• Where the case actually proceeded: Lead case 8:17-cv-00596-DOC (JDEx) (XR Communications v. D-Link Systems, Inc., et al., including NETGEAR). Public trackers disagree on its termination date (RPX/Justia variants show closure 4/18/2022 vs. 5/16/2024), so I would not state a termination date as fact without a PACER pull.
• Parallel PTAB: NETGEAR's challenge to the '376 patent was IPR2023-00136 (NETGEAR, Inc. and Aruba Networks LLC v. XR Communications), which the Board joined to IPR2022-00613 (Samsung) by institution/joinder decision on May 22, 2023. Vivato's PTAB papers in that proceeding list Mirzaie (lead) and Wang (backup) at RAK, Los Angeles — a useful cross-check that RAK remained Vivato's '376 counsel after the district case was consolidated: https://ptacts.uspto.gov/ptacts/public-informations/petitions/[1550534](/patent/1550534)/download-documents?artifactId=24In7TWuPTXAOcirMUc721QXW5pHpNRwsqeerTsabjgY_5vxrBzjlZ4
• Appellate confirmation: XR Communications, LLC v. D-Link Systems, Inc., Nos. 2022-1785, -1787, -1789, -1790, -1791, -1792 (Fed. Cir. May 18, 2023) (nonprecedential), listing "MARC A. FENSTER, Russ August & Kabat, Los Angeles, CA, for plaintiff-appellant. Also represented by MINNA CHAN, BRIAN DAVID LEDAHL, REZA MIRZAIE, JAMES PICKENS." https://cases.justia.com/federal/appellate-courts/cafc/22-1785/22-1785-2023-05-18.pdf

One substantive correction to the existing case summary worth flagging: the 2021 complaint did not assert only the '376 patent — it pleaded three patents, U.S. Pat. Nos. 7,729,728, 10,594,376, and 8,289,939 (RPX lists 3 patents-in-suit for 21-04942; the '376 is the patent later targeted by NETGEAR's IPR2023-00136 and the one referenced in Vivato's IPR2022-00613 mandatory notices).

I'll research the counsel of record for NETGEAR in this case.

Key finding already: this case was administratively closed and consolidated into a lead case. Let me dig into the consolidated docket and NETGEAR's appearances.

The 21-4942 docket was consolidated into a lead case before NETGEAR answered. Let me trace NETGEAR's actual appearances in the consolidated litigation and its IPR counsel.

Bottom line

There is no counsel of record for NETGEAR in Case No. 2:21-cv-04942. No defense appearance was ever filed on this docket. The case was served on NETGEAR on June 22, 2021, but six days later the Court administratively closed it and folded it into a long-pending consolidated action before any answer or appearance was due.

That is the single most important finding, and it flows directly from the docket:

• Doc. #20 (6/25/2021) — Proof of service on NETGEAR via CT Corporation System; answer due 7/13/2021.
• Doc. #21 (6/28/2021) — Minute Order in Chambers by Judge David O. Carter re Consolidation: all future filings to be made only under the low-numbered case, SA CV 17-00596-DOC (JDEx); "Case LA CV 21-04942-DOC (JDEx) is hereby administratively closed. No further filings shall be filed in this case. Any party / counsel not listed on the low numbered case shall file a Notice of Appearance in that case." (Made JS-6. Case Terminated.)

So NETGEAR's answer deadline never matured on this docket, and any counsel it retained were directed to appear in the 2017 lead case instead. The only attorneys listed on the 21-4942 docket are plaintiff-side (Russ August & Kabat: Marc A. Fenster, Reza Mirzaie, Minna Y. Chan, Philip X. Wang, Christian W. Conkle, James N. Pickens).

Metadata caveat: your case header lists this matter as "active." The docket indicates it was administratively closed and JS-6 terminated on 6/28/2021, with the live dispute continuing under 8:17-cv-00596-DOC (JDEx). UniCourt and RPX both record the case as closed (RPX: "Closed: 06/28/2021"). Worth reconciling in the case record.

Known counsel for NETGEAR in the related proceedings

Because there is no appearance here, the most reliable identification of NETGEAR's actual representatives comes from its Petitioner Power of Attorney in IPR2023-00136 (U.S. Pat. No. 10,594,376 — the same patent at issue here; filed Nov. 17–18, 2022; instituted; terminated Oct. 3, 2023 as settled). That document is signed, filed with the USPTO, and names the practitioners expressly.

Notably, no local (C.D. Cal.) counsel appears on the NETGEAR power of attorney — expected, since the POA covers only PTO practice.

---

What I could not verify — and will not guess at

• NETGEAR's district-court counsel of record in the consolidated lead case, 8:17-cv-00596-DOC (JDEx). NETGEAR is named as a defendant in that consolidated action (alongside D-Link, Belkin, Aruba, Ruckus, Ubiquiti, ASUS, Cisco, and Extreme Networks). I was unable to retrieve the defense-side attorney listings for that docket from the sources available. The Federal Circuit's Rule 36-style affirmance in XR Commc'ns v. D-Link Sys., Nos. 22-1785 et al. (Fed. Cir. May 18, 2023), identifies appellate counsel only for the appellees — Jonathan K. Waldrop and Marcus Barber (Kasowitz Benson Torres) for ASUS/Asustek, Sarah E. Piepmeier and Ryan Brodie Hawkins (Perkins Coie) for Cisco, and Daniel W. Richards and Andrew N. Thomases (Ropes & Gray) for Extreme Networks. NETGEAR is listed as a "Defendant," not a "Defendants-Appellee," so no NETGEAR counsel appears in that opinion.
• Counsel in the earlier 2017 action, XR Communications v. NETGEAR, No. 2:17-cv-02959 (C.D. Cal.). Confirmed to exist (it appears as a related case in XR's amended notice of related cases, Doc. #18), but I did not retrieve its docket or appearances.
• Whether Duane Morris also served as NETGEAR's district-court counsel. Plausible and common practice, but unconfirmed by any source I reviewed. Do not treat the IPR counsel list as a district-court appearance list.

---

Suggested verification steps

1. PACER, 2:21-cv-04942 — confirm the docket contains no defense appearance (should show Docs. 1–21 only, terminating 6/28/2021).
2. PACER, 8:17-cv-00596-DOC (JDEx) — pull the "Notice of Appearance" and "Attorneys" party listings for NETGEAR, Inc.; this is where the operative defense counsel of record will be.
3. IPR2023-00136 — docket and POA confirm the Duane Morris team above; the July 2023 pro hac vice papers (Paper 43) and withdrawal motion (Paper 36) may reveal additional NETGEAR-side counsel.
4. Settlement trail — XR and NETGEAR's joint motion to terminate IPR2023-00136 and to keep the "NETGEAR Agreement" confidential (Papers 49–50, Sept. 29, 2023) may identify settlement counsel.
