XR Communications, LLC d/b/a Vivato Technologies v. Aruba Networks, LLC

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

Let me dig deeper into the '376 patent, the Aruba-specific allegations, and the IPR linkage.

Now let me verify the accused products and the fate of the consolidated lead case.

Case Overview & Background

The parties. Plaintiff XR Communications, LLC, doing business as Vivato Technologies, is a Delaware LLC with its principal place of business in Venice, California [Compl. ¶10, XR Communications v. Cisco Systems, No. 6:21-cv-00623-ADA (W.D. Tex.)]. It is a patent-holding entity, not an operating company: it does not make or sell products, and it acquired the former Vivato Inc. patent portfolio through a chain of transactions that ran from Vivato's 2005 wind-down, through Wayout Wireless/Vivato Networks and an Aequitas Capital foreclosure auction, to XR Communications in December 2009 RPX, "Stays Lifted, Wireless Networking Campaign Roars To Life," June 2021. XR's complaints nonetheless lean heavily on the predecessor's history — "founded in 2000 as an $80+ million venture-backed company," "over 400 deployments globally," a portfolio of "over 17 issued patents" — a framing defendants attacked as an attempt "to extract a fee from Defendants for technologies that it neither practices nor commercializes" [Joint Rule 26(f) Report at 4–6, XR Commc'ns v. D-Link Sys., No. 8:17-cv-00596 (C.D. Cal.)]. Defendant Aruba Networks, LLC is a networking/enterprise Wi-Fi company and a wholly owned subsidiary of Hewlett Packard Enterprise Company, which Aruba identified as its corporate parent in its Rule 7.1 disclosure filed September 2, 2021 [Dkt. 243, No. 2:21-cv-04912]. Aruba makes access points, controllers, and the ArubaOS/Aruba Central management stack.

The accused technology. XR accuses Aruba's Wi-Fi access points and routers that implement multi-user MIMO (MU-MIMO) — including devices compliant with IEEE 802.11ax / Wi-Fi 6 — of infringement, and pleads induced infringement through Aruba's manuals and documentation instructing customers in beamforming/MU-MIMO operation [RPX, July 2021, supra]. This mirrors the theory XR ran against Aruba in the 2017 wave, where the accused lineup included the 300/310/320/330/360 Series and the AP-303H, with the Aruba AP-325 used as the exemplary product and claim elements mapped onto 802.11ac features like Group ID Management frames and VHT Compressed Beamforming feedback [Compl., XR Commc'ns v. Aruba Networks, No. 2:17-cv-02945 (C.D. Cal. Apr. 19, 2017)]. The single asserted patent here is U.S. Patent No. 10,594,376 B2, "Directed Wireless Communication" (issued March 17, 2020, from Application 15/486,245, claiming priority to a November 4, 2002 provisional): in one line, a multi-beam "directed signal" system that communicates with client devices through an antenna assembly and updates the spatial distribution of its beams based on feedback received from those client devices — i.e., adaptive beamforming/beam steering in 802.11 networks [IPR2023-00136, Paper 6 (institution decision) at § I.D; IPR2022-00613 Patent Owner Response at § II.A]. The '376 is one of a seven-member family that also includes the '296 and '728 patents from the 2017 campaign.

Procedural posture and why it matters. XR filed this case on June 16, 2021 in C.D. Cal. as part of a coordinated wave of roughly a dozen-plus new suits — many against other defendants in W.D. Tex. before Judge Alan D. Albright, but this one, along with D-Link, Belkin, Netgear, and Ubiquiti, in the Central District — alleging a 35 U.S.C. § 271 cause of action and demanding a jury [Dkt. 1; RPX, June 2021 & Aug. 2021]. Assigned initially to Judge John F. Walter and Magistrate Judge Steve Kim, the case was transferred on June 23, 2021 to Judge David O. Carter and Magistrate Judge John D. Early under General Order 21-01 as related to the 2017 lead case [Dkt. 15], and on June 28, 2021 Judge Carter consolidated it into lead case SA CV 17-00596-DOC (JDEx) and administratively closed the 2:21-cv-04912 docket: "No further filings shall be filed in this case" [Dkt. 16]. That is a material caveat to the case's listed "active" status — the standalone docket is closed and everything moved to the 2017 consolidated action, which was itself terminated May 16, 2024 [DocketAlarm, No. 8:17-cv-00596]. Venue mattered because C.D. Cal. was where XR itself resides and where Judge Carter was already managing the multi-defendant Wi-Fi campaign; consolidation let Aruba ride the existing Markman record, including Special Master David Keyzer's claim construction reports [Dkts. 280, 312, 332, 366]. The case is notable chiefly for its IPR linkage and settlement dynamics: Aruba, Netgear, Samsung, Google, and Cisco petitioned for review of claims 1–34 of the '376 in IPR2022-00613 (filed March 3, 2022), which the Board instituted on October 20, 2022; Netgear and Aruba then filed a substantively identical petition, IPR2023-00136 (Nov. 18, 2022), which was instituted and joined on May 22, 2023 [IPR2023-00136, Paper 6]. Institution triggered a district-court stay (Oct. 26, 2022, Dkt. 548 in No. 8:17-cv-00596), and Belkin/Netgear/Ubiquiti had already dropped claims 22–31 of the '376 in July 2022 [Dkt. 378]. Aruba then settled out of the IPR: the Board terminated Aruba, Samsung, Google, and eero on July 6, 2023, noting the parties had jointly moved to dismiss "the pending District Court litigation between them involving the '376 patent" [IPR2022-00613, Paper 34]. XR settled with Cisco and then Netgear, and on October 3, 2023 — roughly three weeks before the statutory final-written-decision deadline — the Board terminated IPR2022-00613 entirely without ever reaching the merits [IPR2022-00613, Paper 52], a maneuver Ubiquiti later attacked as XR "orchestrat[ing] the termination of the IPR2022-00613 proceeding just before the Board was set to issue a final written decision" [Ubiquiti motion, IPR2024-00148]. The practical result for this case is that the '376's validity was never adjudicated on the merits by the PTAB, and Aruba exited both forums through settlement rather than judgment — against the backdrop of a campaign that was otherwise collapsing, as shown by the Federal Circuit's May 18, 2023 affirmance (nonprecedential) of the indefiniteness invalidity of claims 1–9 and 12 of U.S. Patent 6,611,231 in XR Communications v. D-Link Systems, Nos. 2022-1785 et al.

Sourcing caveats. (1) The complaint in 2:21-cv-04912 (Dkt. 1, with Exhibits A–C) is not reproduced in the free sources I could reach, so the exact Aruba product list asserted against the '376 in the 2021 complaint is inferred from RPX's campaign reporting and from XR's parallel '376 contentions — treat the specific model numbers as the 2017-case lineup rather than confirmed '376 allegations. (2) I did not locate the specific dismissal order terminating Aruba's '376 claims in the consolidated action; the PTAB's July 6, 2023 order is the best evidence that those claims were dismissed as part of the mid-2023 settlement. (3) The outcome of Ubiquiti's IPR2024-00148 petition/motion to reopen IPR2022-00613 is not verified here. (4) Damages figures for this case are not public.

I'll research this case systematically, starting with the docket and core filings.

Key finding already: the Aruba case was consolidated into a 2017 lead case within days. Let me trace the lead case and the IPRs.

Let me dig into the lead case docket, Aruba's participation, and the '376 IPR outcomes.

Bottom line

Plaintiff XR Communications, LLC d/b/a Vivato Technologies was represented exclusively by Russ August & Kabat (RAK), Los Angeles — the same firm that ran the entire Vivato wireless-networking campaign (2017–2023). No in-house counsel and no separate "local counsel" firm ever appeared; RAK's L.A. office served that function in C.D. Cal. Every name below is tied to the docket or to filings in the consolidated lead case or the parallel PTAB/Federal Circuit proceedings; I did not recover a full PACER attorney-appearance report for this short-lived docket, so role characterizations of the non-signing attorneys are inferred from firm filings and related cases (flagged where so).

Counsel of record

Procedural caveats you should carry forward

• This docket is administratively closed. On June 28, 2021, Judge David O. Carter ordered 2:21‑cv‑04912 consolidated into the low-numbered lead case 8:17‑cv‑00596‑DOC (JDEx) and administratively closed it (Dkt. 16; case transferred from Judge Walter to Judge Carter at Dkt. 15). The order directed that "any party/counsel not listed on the low numbered case shall file a Notice of Appearance in that case." So "counsel of record" for the Aruba '376 case after 6/29/2021 is technically the appearance list in 8:17‑cv‑00596, which is the same RAK team.
• Attorney list sourcing. The six-name list matches the docket-derived attorney roster for 2:21‑cv‑04912 (Justia/UniCourt docket mirrors) and the RAK signature block used across the 2021 XR complaints. I could not pull a live PACER docket sheet for this case, so I have not verified pro hac vice orders or any withdrawal notices specific to this docket; nothing in the public record suggests any appeared.
• Nothing sealed on the plaintiff's side affected counsel identification; the only sealing activity in this campaign concerned XR's Rule 7.1 interested-parties disclosure (litigation-funding related), filed under seal in the 2017 Aruba case (2:17‑cv‑02945, Dkts. 15–18).

Relevant context for the experience notes

• The '376 patent (10,594,376) asserted here was also challenged in IPR2022‑00613 (Samsung/Google/Cisco, instituted Oct. 20, 2022) and IPR2023‑00136 (NETGEAR + Aruba, joined May 22, 2023) — Mirzaie/Wang were XR's PTAB team throughout, and Aruba/Netgear identified 2:21‑cv‑04912 as a related matter in their mandatory notices.
• RAK's XR work ended adversely in part: the Fed. Cir. affirmed invalidity of the '231 patent claims on collateral estoppel in XR Communications v. D-Link, No. 2022‑1785 (May 18, 2023), with Fenster arguing and Chan, Ledahl, Mirzaie and Pickens on the brief.

Key sources: Dkt. 1 (complaint, Mirzaie signature), Dkt. 14 (amended notice of related cases), Dkt. 15 (transfer order), Dkt. 16 (consolidation/administrative closure); Justia docket 2:2021cv04912; Unified Patents litigation portal entry for 2:21‑cv‑04912; IPR2023‑00136 institution/joinder decision and IPR2022‑00376 & IPR2022‑00613 mandatory notices (RAK power of attorney, Jan. 25, 2023; updated notices, May 4, 2023); XR Communications, LLC v. D-Link Systems, Inc., Nos. 2022‑1785 et al. (Fed. Cir. May 18, 2023) (counsel listing).

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

Let me verify firm affiliations and offices for the Aruba counsel identified on the docket.

Bottom line

The docket in 2:21-cv-04912 itself is only 16 entries long and ends on June 28, 2021, when Judge Carter consolidated the case into the earlier lead action and administratively closed it: "LA CV 21-04912-DOC (JDEx) shall be consolidated with SA CV 17-00596-DOC (JDEx). All future filings shall be filed only under the low number case… Any party / counsel not listed on the low numbered case shall file a Notice of Appearance in that case." (Dkt. 16, 6/28/2021; JS-6 terminated.) Aruba was not even served until August 12, 2021 (proof of service, lead-case Dkt. 238) — i.e., after the consolidation — so no appearance by Aruba's counsel appears on the 2:21-cv-04912 docket sheet itself. All of Aruba's counsel activity is recorded in the lead case, SACV17-00596-DOC (JDEx), where Aruba's Answer was expressly filed as its response to the 2:21-cv-04912 complaint (Dkt. 242, 9/2/2021: "Answer to Complaint in Case No. 2:21-cv-04912-DOC-JDE, Dkt. 1").

Aruba is represented by Covington & Burling LLP, the same firm (and largely the same team) that defended Aruba in the 2017 wave (XR Commc'ns v. Aruba Networks, 2:17-cv-02945) and that serves as Aruba's PTAB counsel (IPR2018-00701, -00725, -00726).

Counsel of record for Aruba Networks, LLC

Caveats and non-Aruba counsel to avoid confusion

• Sarah E. Piepmeier (Perkins Coie) appears in the docket text as "added to party Aruba Networks LLC" at Dkt. 252, but that is an artifact of her filing the joint Rule 12(c) motion on behalf of all defendants (Dkt. 252–253) — she is Cisco's counsel, not Aruba's. Same for Kasowitz (ASUS), Ropes & Gray (Extreme), Duane Morris (Netgear/Belkin) and Dykema/Fox (Ubiquiti) — they filed jointly with Aruba on claim construction and the '728 judgment-on-the-pleadings motion.
• No in-house counsel for Aruba or Hewlett Packard Enterprise appears on the docket. Aruba's corporate disclosure identifies HPE as its corporate parent (Dkt. 243).
• No sealed or withheld appearance issue: the counsel list above is drawn from public docket entries; nothing about Aruba's representation was sealed. The sealed material in this case relates to damages, expert reports and the patent-purchase/inequitable-conduct discovery, not to counsel identity.
• Federal Circuit appeal (Nos. 2022-1785, -1787, -1789, -1790, -1791, -1792, decided May 18, 2023) lists ASUS, Cisco and Extreme's appellate counsel by name in the opinion; I could not confirm from the sources I retrieved which Covington attorney signed Aruba's appellee brief — treat that as unsourced.
• The lead case was stayed on October 26, 2022 pending the '376 IPR (Dkt. 548), so Aruba's appearances have not been updated since then in the materials available.
