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

Case Overview — Ruckus Wireless, Inc. v. XR Communications, LLC (IPR2018-01018), and the underlying Wi‑Fi infringement campaign

Parties. The patent owner, XR Communications, LLC d/b/a Vivato Technologies ("XR/Vivato"), is a Delaware LLC with its principal place of business in Venice, California, and is, functionally, a patent-holding/licensing entity: it is "the sole owner by assignment of all right, title, and interest" in the patents it asserts, and it does not appear to make or sell accused products (its own complaints describe Vivato, Inc. — the 2000-vintage, $80M+ venture-backed smart-antenna Wi‑Fi infrastructure start-up whose inventions list Siavash Alamouti, Ken Biba, William Crilly, James Brennan, Edward Casas and Vahid Tarokh — in the past tense, as a source of "over 17 issued patents" now held by XR; see XR's complaints, e.g., E.D. Tex. No. 2:23‑cv‑00202, Dkt. 1 ¶¶10–16). Defendants in the parallel litigations have been blunter, telling the court that XR is "adopting the name of Vivato, Inc., a failed wireless technology company" and seeking to "resurrect" its "patent holdings by broadening claims drafted nearly two decades ago to cover Defendants' present-day technologies" (Defendants' Opening Claim Construction Brief, Ex. 1013 in IPR2018‑00762). On the other side, Ruckus Wireless, Inc. is a Wi‑Fi infrastructure vendor (enterprise access points and controllers); at the relevant time it was a subsidiary of ARRIS (its Rule 7.1 disclosure in the N.D. Cal. action identifies ARRIS International plc and ARRIS US Holdings as parents, No. 3:18‑cv‑01992‑WHO, Dkt. 136), and Ruckus's parallel PTAB filings were captioned with "ARRIS SOLUTIONS,

Key Legal Developments & Outcome — XR Communications v. Ruckus Wireless (the litigation underlying IPR2018‑01018)

Framing note. IPR2018‑01018 has no “complaint/answer/verdict” of its own; it is the PTAB track of a much larger, consolidated district‑court campaign over the ’728 patent family (U.S. 7,062,296 / 7,729,728 / 6,611,231). The chronology below runs the district‑court case that birthed the ’728 petition (XR Commc’ns v. Ruckus Wireless, C.D. Cal. No. 2:17‑cv‑02961‑AG‑JCG → N.D. Cal. No. 3:18‑cv‑01992‑WHO), its companion Arris case (N.D. Cal. No. 3:18‑cv‑02736‑WHO), and the six parallel IPRs that decided the patents. It does not re‑cover party/counsel background already summarized above.

1. Filing and initial pleadings (2017)

No counterclaims of substance were ever reached on the merits — the ’296/’728 claims evaporated in the PTAB and the ’231 claims died on indefiniteness, so all remaining claims/counterclaims were disposed of by dismissal/judgment rather than trial.

---

2. Pre‑trial motions of substance

a) Venue / transfer (the decisive early fight).

• 2017‑07‑14: Ruckus renews its motion to dismiss for improper venue or transfer to N.D. Cal. (Dkt. 27), supported by the Rabinovitsj declaration; hearing reset to 2017‑10‑16.
• 2017‑08‑02/03: XR’s ex parte application for venue discovery is granted in part (Dkt. 31) — venue discovery “strictly limited to the venue issues.” Ruckus then moves to limit discovery under In re Cray (Dkt. 73, filed 2017‑10‑30), and XR’s motion to compel venue discovery (Dkt. 85) is denied on 2018‑01‑22 (Dkt. 93). XR’s attempt to quash the deposition of its own counsel Kent Shum fails on 2017‑12‑07 (Dkt. 83).
• 2018‑03‑30 — Judge Guilford GRANTS Ruckus’s motion and TRANSFERS all of Vivato’s claims against Ruckus to the Northern District of California (Dkt. 123, 17 pp.), terminating the C.D. Cal. case. This is the single most consequential pre‑trial ruling: it removed the case from Judge Guilford’s consolidated MDL‑style structure and put it before Judge William H. Orrick III in N.D. Cal. (No. 3:18‑cv‑01992‑WHO, filed 2018‑04‑02; reassigned to Orrick 2018‑04‑20, Dkt. 131).

b) Consolidation in C.D. Cal. (for context). On 2017‑10‑02 Judge Guilford consolidated ten XR suits (including Ruckus) into lead case 8:17‑cv‑00596‑AG‑(JCGx) “for all purposes except trial,” set a 5‑day jury trial for 2019‑03‑19, and ordered private ADR (Dkt. 51; see also Dkt. 40, Oct. 2, 2017 minutes). Those dates were overtaken by the transfers and the IPRs; no trial in any XR case ever occurred on these patents.

c) Stay pending IPR. The N.D. Cal. docket shows a multi‑year gap between the 2018 pleadings and the 2021 claim‑construction ruling, consistent with the case being held while the six IPRs ran. Caveat: I could not open the specific stay order in 3:18‑cv‑01992, so I am flagging the stay as strongly implied by the docket timeline and by the fact that claim construction did not occur until after the 2019 PTAB decisions — not as a document I verified.

d) Summary judgment / judgment on the pleadings. There was no traditional SJ motion on infringement or damages. Instead, the ’231 indefiniteness ruling was converted into judgment by stipulation (see §4), and the ’296/’728 claims were disposed of by PTAB cancellation. The collateral‑estoppel cascade came later, in the other XR cases: on 2022‑01‑04 Judge Carter entered the order (Dkt. 274 in lead case 8:17‑cv‑00596‑DOC‑JDE) granting judgment on the pleadings that all ’231 claims were invalid based on the N.D. Cal. indefiniteness judgment; final judgments followed on 2022‑04‑15 in Cisco (2:17‑cv‑02951, Dkt. 42) and

I'll research the counsel of record for the petitioner/plaintiff, Ruckus Wireless, in this PTAB proceeding.

Important framing note

IPR2018‑01018 is not a district‑court infringement action — it is an inter partes review before the PTAB, so there is no PACER docket and no "plaintiff" in the Rule 3/7 sense. The party that filed and prosecuted the proceeding is the petitioner, Ruckus Wireless, Inc. (captioned "Ruckus Wireless, Inc. et al."), which is the functional equivalent of the plaintiff here. The corresponding infringement suit ran separately in the Central District of California (XR Communications, LLC d/b/a Vivato Techs. v. Ruckus Wireless, Inc., No. 2:17‑cv‑02961‑AG‑JCG), later in N.D. Cal. (No. 3:18‑cv‑01992‑WHO). Everything below relates to the PTAB representation unless noted.

PTAB filings are public (PTAB E2E/P-TACTS), so nothing here is sealed — but note the caveat on the specific document I could and could not view, below.

Counsel of record for the petitioner (Ruckus Wireless)

1. John M. Baird — lead counsel

• Firm: Duane Morris LLP, Washington, D.C. (505 9th Street NW, Suite 1000)
• Registration: Reg. No. 57,585
• Sourcing: Listed as lead counsel on the § 42.10(b) Power of Attorney filed in the companion petitions brought by the same petitioner group — Ruckus Wireless, Inc., ARRIS Solutions, Inc., Belkin International, Inc. and Netgear, Inc., Case IPR2018‑01016 ('231 patent), dated Aug. 6, 2018 — and in the parallel '296‑patent petition in the same campaign. (POA, IPR2018‑01016)
• Note: Duane Morris was the outside firm of record for the Ruckus/ARRIS side across this IPR wave; the Hera Wireless petitions from the same period were even captioned "Ruckus Wireless, Inc., et al. c/o Duane Morris LLP" (IPR2018‑01419/‑01420/‑01421).

2. Carol Ansley — back‑up counsel; in‑house (ARRIS)

• Firm/office: ARRIS, 3871 Lakefield Drive, Suwanee, Georgia (in‑house patent counsel; Ruckus was an ARRIS subsidiary following the 2016 Brocade/ARRIS transaction)
• Registration: Reg. No. 76,331
• Sourcing: Listed as back‑up counsel on the same IPR2018‑01016 POA and on the POA for the related Ruckus/ARRIS '296 petition.
• Note: A recurring in‑house representative for the ARRIS/Ruckus side in PTAB proceedings in 2018–2020, including IPR2018‑01739.

3. Duane Morris attorneys appearing for Ruckus/ARRIS in the related IPR family (not individually confirmed on the ‑01018 docket)

• Matthew S. Yungwirth — partner, Duane Morris, Atlanta, GA; appeared for Ruckus Wireless and Netgear in Juniper Networks v. Chrimar Systems, IPR2016‑01391, and has handled numerous PTAB matters. (deposition transcript appearances)
• Christopher J. Tyson — Duane Morris, Washington, D.C. (Reg. No. 63,850); listed lead counsel for Ruckus/ARRIS in IPR2018‑01739 and named petitioner counsel in the Hera Wireless IPRs.
• Patrick D. McPherson — Duane Morris, Washington, D.C.; Duane Morris's lead appellate contact for ARRIS in the ChanBond § 315(b) appeals (Fed. Cir. Nos. 2018‑2426 et seq.).

---

Sourcing caveat (please read before relying on this)

• I was able to confirm the Duane Morris / John Baird + Carol Ansley team from the § 42.10(b) powers of attorney filed in the companion petitions of the same petitioner group filed within weeks of IPR2018‑01018 (IPR2018‑01016 for the '231 patent, and the parallel '296 petition). This is strong circumstantial evidence for ‑01018, but I did not directly retrieve the ‑01018 POA (Paper 2, "Petitioners Power of Attorney," filed May 3, 2018) or the caption page of the ‑01018 Petition (Paper 1), nor did I open the Final Written Decision (Paper 39, Nov. 12, 2019), each of which lists counsel of record on its face.
• To verify on the record, pull from PTAB E2E / P‑TACTS: Paper 1 (Petition, cover page and signature block), Paper 2 (Power of Attorney), and Paper 39 (Final Written Decision, Nov. 12, 2019), docket page: Docket Alarm – IPR2018‑01018 and Patexia document list.
• I found no evidence of separate "local counsel" in the PTAB proceeding — that concept does not apply at the Board. If you also want Ruckus's counsel in the C.D. Cal. / N.D. Cal. infringement suits (where Ruckus was the defendant, and where XR Communications is the plaintiff), that is a separate team and I have not verified it here; the plaintiff-side counsel visible in the docket data are XR/Vivato's counsel (Marc Fenster, Reza Mirzaie, Kent Shum, Philip Wang, Christian Conkle, Minna Chan — Russ August & Kabat), not Ruckus's.

Case outcome context

The Board instituted (Paper 12) and, per the Final Written Decision of Nov. 12, 2019 (Paper 39), held claims 1, 7, and 16 of U.S. 7,729,728 unpatentable. The cancellation of all asserted '728 claims was later cited in the C.D. Cal. cases (e.g., XR Communications v. Cisco, No. 2:17‑cv‑02951, Dkt. 42, Apr. 15, 2022) as the basis for dismissing the '728 claims and counterclaims.

I'll research the counsel of record for XR Communications in this IPR and any related district court litigation.

Initial results point to Noroozi PC. Let me verify against the actual IPR2018-01018 filings and check for any counsel changes.

Noroozi PC appears to be patent owner's counsel in the 2018 IPR series. Let me confirm specifically for IPR2018-01018 and check for later substitution.

Short answer

This is a PTAB inter partes review, not a district-court infringement action, so the "defendant" is formally the Patent Owner/Respondent — XR Communications, LLC d/b/a Vivato Technologies. Its counsel of record in IPR2018-01018 was the boutique IP firm Noroozi PC (Santa Monica, CA / Sugar Land, TX). There is no "local counsel" role at the PTAB, and no in-house attorney appeared on the docket.

Counsel of record for XR Communications / Vivato (Patent Owner)

Sourcing and how I verified it

• Docket (IPR2018-01018): filed 2018‑05‑03; terminated 2018‑11‑12, 2019; Paper 39 = Termination/Final Written Decision (Nov. 12, 2019); panel of APJs Barbara Parvis, James Mayberry, Terrence McMillin — docketalarm and Patexia document list.
• Counsel designation: XR/Vivato's Mandatory Notices under 37 C.F.R. § 42.8, filed May 24, 2018 in the companion Ruckus IPR (the notice's related-matters table expressly lists XR Communications, LLC d/b/a Vivato Technologies, Case IPR2018‑01018, May 3, 2018) — PTAB filing copy.
• PHV admission in 1018 itself: Mot. for Admission Pro Hac Vice of Kayvan Noroozi (Paper 5, May 24, 2018); Order granting (Paper 11, Oct. 3, 2018) — corroborates the Noroozi PC team in this specific case.

Caveats worth flagging

1. The § 42.8 designation I could retrieve was filed in the companion matter IPR2018‑01016, not 1018; the counsel listing is identical across the parallel Ruckus IPRs (1016/1017/1018), and the 1018 docket shows the corresponding Noroozi PHV motion and order, so I treat the designations as the same. I could not open the signature block of Paper 39 directly to re-confirm end-of-case counsel; no motion to withdraw or substitute counsel appears on the 1018 docket, so Noroozi PC appears to have remained counsel through the Final Written Decision.
2. Firm transition, later matters: By 2019–2021 Vivato was represented instead by Russ August & Kabat (Reza Mirzaie, Philip X. Wang, Christian Conkle, Kent N. Shum) in the C.D. Cal. / W.D. Tex. / N.D. Cal. cases and in later IPRs (e.g., IPR2022‑00367, where Wang was designated lead counsel). That change is documented for those later matters but does not appear on the 1018 docket, so it post-dates this IPR.
3. No in-house counsel for XR/Vivato appears on the PTAB docket.
4. Bios: I did not find firm-published biographies adequate to characterize the individual attorneys' broader case histories beyond this Vivato/Ruckus IPR family; I have not attributed any specific past cases to them that I could not verify in a filing. The "notable experience" line for each is therefore limited to what the docket itself establishes (Vivato's lead/back-up team in the coordinated 2018 Ruckus IPRs on the '728 family).
5. If what you actually need is district-court defense counsel in the co-pending litigation, note the posture: in XR Communications v. Ruckus Wireless, No. 3:18‑cv‑01992‑WHO (N.D. Cal.), XR/Vivato was the plaintiff and Ruckus/Arris were defendants (claim construction order, Dkt. 191, Sept. 1, 2021; aff'd, XR Commc'ns v. Arris Solutions, No. 22‑1125 (Fed. Cir. 2023)). XR's counsel there was Russ August & Kabat (Reza Mirzaie filed the supporting declaration). I have not verified Ruckus/Arris's defense counsel in that case.
