Case Overview: XR Communications, LLC v. Aruba Networks, Inc., No. 2:17-cv-02945-AG (JCGx) (C.D. Cal.)

The parties. Plaintiff XR Communications, LLC, which litigates under the trade name Vivato Technologies, is a Delaware LLC with its principal place of business in Venice, California. It is not an operating company in any meaningful commercial sense: it is the patent-holding residue of Vivato, Inc., an $80M+ venture-backed Wi-Fi infrastructure startup founded in 2000 whose engineers included Siavash Alamouti, Ken Biba and Vahid Tarokh and which sold beamforming phased-array "packet steering" base stations before winding down. XR Communications pleads Vivato's operating history in its complaints (see, e.g., Compl. ¶¶ 11–15 in the related actions, describing "over 400 deployments globally"), but Stanford's NPE Litigation Database classifies XR Communications in the "failed startup" asserter category — i.e., a patent monetization vehicle built on a defunct operating company's portfolio. Defendant Aruba Networks, Inc. is the enterprise WLAN/access-point business that Hewlett Packard Enterprise acquired in 2015 — a genuine operating company and one of the largest enterprise Wi-Fi vendors in the market. Aruba answered and counterclaimed for invalidity (see Dkt. 29, pro hac vice admission of David A. Garr for "Counter Claimant Aruba Networks, Inc.").

The accused technology. The case is, in substance, a standards-implementation case. XR Communications accused Aruba's 802.11ac ("Wi-Fi 5") Wave 2 access points — the Aruba 300, 310, 320, 330 and 360 Series and the AP-303H Series (e.g., AP-304/305, AP-314/315, AP-324/325, AP-334/335, AP-365/367) — alleging that implementing multi-user MIMO beamforming under IEEE 802.11ac-2013 necessarily practices the claims. The mapping relies on standard mechanics: Group ID Management frames and VHT-SIG-A1 Group ID fields to associate a client with a "beam downlink," and VHT Compressed Beamforming feedback frames as the "uplink transmission" from which the AP decides whether to move the client to a different beam. The complaint identifies the Qualcomm QCA9990 radio in the AP-325 as the transceiver (RPX records 32 accused products across the case). Notably, XR sued the AP OEMs rather than Qualcomm, the chipset supplier whose radios implement the standard's beamforming — a pattern that spread the defense cost across the industry rather than concentrating it.

The patents. Three patents,

Bottom line

Plaintiff XR Communications, LLC d/b/a Vivato Technologies was represented in this case exclusively by the Los Angeles patent boutique Russ, August & Kabat ("RAK"). The docket for 2:17-cv-02945 shows four RAK attorneys actually appearing/filing on Plaintiff's behalf — Reza Mirzaie (the workhorse of record), Marc A. Fenster (lead counsel across the consolidated Vivato campaign and on appeal), Kent N. Shum, and Christian W. Conkle — plus James N. Pickens, who appeared and then formally withdrew in January 2018 (Dkt. 33). No in-house counsel and no second outside firm appeared in this docket. I could not verify a signed appearance by Philip X. Wang or Minna Y. Chan in this case specifically (they appear on RAK signature blocks in the consolidated/later Vivato matters).

Attorney detail

Marc A. Fenster — Founding/managing partner of RAK; first-listed counsel on the firm's signature blocks for XR Communications/Vivato throughout the ten-case C.D. Cal. campaign and the appeals. He is the attorney credited on the Federal Circuit's 2023 nonprecedential decision affirming invalidity of claims 1–9 and 12 of the '231 patent on collateral-estoppel grounds in the consolidated C.D. Cal. cases — XR Communications, LLC v. D-Link Systems, Inc., Nos. 2022-1785 et al. (Fed. Cir. May 18, 2023) ("MARC A. FENSTER, Russ August & Kabat, Los Angeles, CA, for plaintiff-appellant") — an appeal in which Aruba was a named defendant-appellee. Caveat: I found no paper in the 2:17-cv-02945 docket signed by Fenster; his status as lead counsel is established at the campaign/appellate level rather than by a local appearance here.

Reza Mirzaie — The attorney whose name appears on nearly every Plaintiff filing in this docket, from the original Complaint (4/19/2017) through the First Amended Complaint (Dkt. 22) and the sealed Local Rule 7.1-1 interested-parties papers (Dkts. 15–18) that the Court permitted to be filed under seal. He also handled service (Dkt. 13) and remained Plaintiff's counsel of record in the consolidated Vivato matters and on the 2023 Federal Circuit appeal (listed in the opinion's counsel line). He is the most accurate answer to "who is counsel of record" for this case.

Kent N. Shum (CA SBN 259189) — RAK associate/partner who filed Plaintiff's answer to Aruba's counterclaim (Dkt. 25, 7/31/2017) and who appears on RAK's XR Communications signature blocks in the parallel C.D. Cal. actions. His docket footprint here is narrow — one substantive filing.

Christian W. Conkle — RAK attorney who handled the case-management papers in this docket: the August 2017 stipulation continuing the scheduling conference (Dkt. 28) and the Joint Rule 26(f) Discovery Plan (Dkt. 31) submitted on behalf of Vivato. Also appears on RAK's later Vivato filings (e.g., E.D. Tex. 2023–2025).

James N. Pickens (CA SBN 307474) — Appeared for XR Communications and then filed the G-123 Notice of Appearance or Withdrawal of Counsel on January 22, 2018, expressly stating he was "no longer counsel of record" (Dkt. 33). He later resurfaced on RAK's XR Communications filings, including the 2023 Federal Circuit appeal (listed in the opinion's counsel line) and the 2023–2025 E.D. Tex. cases, so the withdrawal appears to have been a firm-departure/return event rather than a permanent exit from the representation. I have not verified the reason.

Not confirmed as counsel of record in this docket (name only): Philip X. Wang (CA SBN 262239) and Minna Y. Chan (CA SBN 305941) appear on RAK's consolidated-case and later-case signature blocks for XR Communications but do not appear on any 2:17-cv-02945 filing I could locate. Treat them as campaign counsel, not record counsel here.

Procedural context that affects "counsel of record"

• The case was consolidated for all pretrial purposes into lead case SACV 17-0596-AG (JCGx) by minute order of October 2, 2017 (Dkt. 32), and then stayed and administratively closed as to all consolidated defendants pending IPR outcomes (Dkt. 34, May 22, 2018, JS-6; implementing the April 10, 2018 stay order at Dkt. 153 in the lead case). A closing Report on the Determination of an Action (Dkt. 35) followed.
• Because of the stay, the operative roster of Plaintiff's counsel is frozen as of early-to-mid 2018. After the stay, filings in the consolidated proceeding generally went to the lead case number, not 2:17-cv-02945.
• Sealed material: Plaintiff's Local Rule 7.1-1 Certification and Notice of Interested Parties and the supporting Mirzaie declaration were filed under seal (Dkts. 15–18), so the ownership/funding disclosures behind those filings are not public. That sealing does not, however, obscure the identity of counsel.
• No in-house counsel for XR Communications/Vivato appears on this docket, consistent with Vivato being a non-practicing patent owner.
• Defense-side cross-reference (for docket verification, not asked): Aruba was represented by Mark Y. Chen (local counsel) with David A. Garr admitted pro hac vice (Dkt. 27, granted at Dkt. 29), and Robert Haslam of Covington & Burling appeared for Aruba at later consolidated depositions.

Let me examine the docket entries and additional Covington counsel.

Counsel of Record — Defendant Aruba Networks, Inc.

XR Communications, LLC v. Aruba Networks, Inc., No. 2:17-cv-02945-AG (JCGx) (C.D. Cal., filed Apr. 19, 2017)

Sourcing caveat up front: I was not able to open the raw PACER docket sheet directly. The docket reconstruction below rests on the Patexia and RPX docket mirrors of No. 2:17-cv-02945, CourtListener RECAP documents from the consolidated lead case, and Aruba's PTAB filings in the parallel IPRs (which identify Aruba's litigation team and are signed by the same lead counsel). Entry numbers and dates are given so each item can be verified on PACER. The case is a short docket — 35 entries — and was administratively closed on May 22, 2018.

Counsel who appeared of record in 2:17-cv-02945

That is the complete set of Aruba appearances reflected in the No. 2:17-cv-02945 docket as mirrored; both were entered on behalf of Aruba as defendant and counterclaimant (Aruba pleaded counterclaims, per the "Counter Claimant Aruba Networks, Inc." designation in the Doc. 29 order).

Attorneys on the Aruba team whose district-court appearance is not confirmed in this docket

Procedural context that limits "counsel of record" here

• Consolidation (Doc. 32, Oct. 2, 2017): Judge Andrew J. Guilford consolidated this case and nine companion XR Communications actions into lead case 8:17-cv-00596-AG (JCGx) for all purposes except trial. From that point, filings and appearances ran in the lead case, which is why post-2017 Aruba-side activity (including the 2022 depositions) shows Covington attorneys who never separately appeared in No. 2:17-cv-02945.
• Stay and administrative closure (Doc. 34, May 22, 2018): the Court stayed and administratively closed the consolidated cases pending termination of the IPRs Aruba and other defendants had filed. Doc. 35 (July 31, 2019) is the closing report on the patent action. This is the "stayed" status in the case metadata.
• Appellate phase: Aruba Networks, Inc. and Aruba Networks LLC appear as defendants/appellees in the Federal Circuit appeals from the consolidated litigation, XR Communications, LLC v. D-Link Systems, Inc., Nos. 2022-1785 et al. (Fed. Cir. May 18, 2023) (affirming indefiniteness invalidity of claims 1–9 and 12 of the '231 patent on collateral-estoppel grounds). I could not confirm from the opinion text which firm signed for Aruba on appeal — the reported counsel line I retrieved did not list Aruba's appellate counsel, so I am not attributing appellate representation to Covington or any other firm without verification.

What I could not verify

• Whether a formal substitution or withdrawal of Garr/Chen was ever docketed after the stay (no such entry appears in the mirrored docket).
• Whether Aruba later appeared through HPE's legal department or a different firm for the appellate stage.
• Any sealed filings naming counsel — the concerning entries here (PHV application attachments, stipulations) appear on the public docket, so this is a low-risk gap, but PACER should be checked for any restricted documents.

Bottom line: the two counsel of record for Aruba in this case are David A. Garr (Covington & Burling, Washington, DC) as lead counsel, admitted pro hac vice, and Mark Y. Chen (Covington & Burling, Los Angeles) as local counsel — with Jay I. Alexander functioning as PTAB back-up counsel and Robert Haslam and Kee Young Lee working the matter in the consolidated lead case.
