Unified Patents v. Dynamic Mesh Networks Inc.

Unified Patents has initiated an Inter Partes Review (IPR) against Dynamic Mesh Networks Inc. (d/b/a MeshDynamics) challenging U.S. Patent No. 11,368,537. Unified Patents operates as a member-based organization dedicated to deterring frivolous patent litigation, primarily by challenging patents held by Non-Practicing Entities (NPEs) through IPRs at the Patent Trial and Appeal Board (PTAB). Dynamic Mesh Networks Inc. appears to be a patent owner and asserter in the wireless networking space, having engaged in patent infringement lawsuits against major technology companies such as Cisco Systems, Inc.. The company’s focus on patent monetization in high-tech sectors, particularly wireless mesh networking, positions it as a potential NPE or patent assertion entity that Unified Patents typically targets.

The patent at issue, US 11,368,537, broadly describes a "High performance wireless network". This patent focuses on wireless mesh networks that utilize multiple data communication nodes organized in a tree-like structure, communicating with an access server. Key technical features include self-configuration, automatic load balancing to avoid data congestion, failover capabilities if a node becomes inoperable, support for software upgrades, and the ability to handle both isochronous and asynchronous application requirements within the same network. While the specific accused products in this IPR are not detailed, Dynamic Mesh Networks Inc. has previously asserted related patents against Cisco's mesh networking equipment and solutions, including access points, control systems, wireless controllers, SD-WAN solutions, and VoIP collaboration products.

This IPR (IPR2025-01303) is being heard by the Patent Trial and Appeal Board (PTAB). The procedural posture, as per the case metadata, indicates the petition was "Instituted." However, a specific USPTO status update from March 3, 2026, for "Dynamic Mesh Networks, Inc. d/b/a MeshDynamics, IPR2025-01303" notes a "Decision vacating decision granting institution, and denying institution – Paper 14 (Squires March 3, 2026)". This indicates that while the petition may have initially been granted institution, that decision was subsequently vacated, and institution was ultimately denied, which contradicts the provided prompt's status. The PTAB is a crucial venue for challenging patent validity, and recent trends show an increased focus on director review and discretionary denials, making the outcome of such proceedings highly scrutinized. This case is notable due to Unified Patents' ongoing efforts to mitigate patent assertion risks from NPEs in critical technology sectors like wireless networking, and the dynamic nature of institution decisions at the PTAB, particularly with increased director-level involvement in reviewing institution grants.

I'll research this thoroughly. Note the case is an IPR at the PTAB, but the task asks about the patent infringement litigation — which points to the parallel district court case(s) involving Dynamic Mesh Networks. Let me search both tracks.

I've found critical discrepancies. Let me verify the parties and gather the litigation timeline in detail.

⚠️ Threshold Correction Before the Timeline

Two points must be flagged up front, because they materially affect the requested chronology:

1. Party discrepancy (metadata vs. primary sources). The case metadata lists the petitioner/plaintiff as "Unified Patents." Every primary source I located — the PTAB's own Paper 14, the public PAIR/PTAB docket, and the petition itself — identifies the petitioner in IPR2025‑01303 as Cisco Systems, Inc., not Unified Patents. The caption on the March 3, 2026 Director Review order reads: "CISCO SYSTEMS, INC., Petitioner, v. DYNAMIC MESH NETWORKS, INC. D/B/A MESHDYNAMICS, Patent Owner." (PTAB Paper 14). Per the operating rules I default to the metadata for party names, but the contradiction is stark and I flag it explicitly: treat Cisco, not Unified Patents, as the real party adverse to Dynamic Mesh based on the docket. (It is possible the metadata conflated this file with a separate Unified Patents filing, but I found no Unified Patents proceeding captioned with this number.)

2. Status correction. The prior summary's hint that institution "may have been" granted but then denied is now confirmed. The Board issued a Notice granting institution (Paper 11), but the Patent Owner statutorily disclaimed the entire '537 patent before that Notice entered; on Director Review, the Director vacated the institution determination and denied institution — Paper 14, March 3, 2026 (Director John A. Squires). So IPR2025‑01303 is not "instituted" as a live trial; it was terminated at the institution stage. The metadata's "Pending – Instituted" is inaccurate.

The "Litigation" — Clarification

IPR2025‑01303 is an administrative PTAB proceeding, not a district‑court infringement action. The parallel district‑court patent infringement litigation is Dynamic Mesh Networks, Inc. d/b/a MeshDynamics v. Cisco Systems, Inc. (E.D. Tex.) together with Cisco's mirror‑image declaratory‑judgment action (N.D. Cal.). The chronology below covers that litigation, with the PTAB proceedings addressed in the last section (as the task requests).

Patents in suit (the "Patents‑in‑Suit" across the campaign): U.S. 11,368,537 (’537, "High performance wireless network"); 7,420,952 (’952); 7,885,243 (’243); 7,894,385 (’385); 8,520,691 (’691); 8,477,762 (’762); 8,514,852 (’852); 9,049,000 (’000). All trace to inventor/founder Francis daCosta of MeshDynamics.

Chronology of Key Developments

1. Filing & initial pleadings

I'll research the petitioner/plaintiff-side counsel. First, note the critical framing issue flagged in the prior sections: the metadata names "Unified Patents" as petitioner, but primary sources identify Cisco Systems, Inc. as the petitioner in IPR2025-01303. Let me verify counsel for both possibilities and for the related district court litigation.

I have strong primary-source data. Let me run a few more targeted searches to (a) confirm whether Unified Patents actually filed this IPR, (b) pin down the Desmarais LLP petitioner team, and (c) nail down the district-court plaintiff's (MeshDynamics') counsel roster and firms.

Counsel of Record — Plaintiff/Petitioner Side

⚠️ Framing correction (carry-over from the prior sections)

This task asks for "plaintiff" counsel in "this patent infringement case." Two things must be flagged before naming anyone:

1. IPR2025‑01303 is not an infringement case — it is a PTAB inter partes review. There is no "plaintiff"; the party on the offensive is the petitioner. The patent‑owner counterpart (Dynamic Mesh Networks) was covered in the prior "Defendant representatives" section.
2. Metadata vs. primary sources. The metadata names Unified Patents as the plaintiff/petitioner. Every primary source — the petition's mandatory notices, the Board's institution/director‑review papers — identifies the petitioner as Cisco Systems, Inc. No searched source shows Unified Patents appearing in IPR2025‑01303. Per operating rules I default to the metadata for the party name, but I flag that no Unified Patents counsel can be identified for this docket because Unified Patents does not appear to be a party to it.

I therefore give you (A) petitioner‑side counsel in the IPR, (B) the absence of any Unified Patents appearance, (C) the actual plaintiff‑side counsel in the parallel district‑court infringement suits (Dynamic Mesh Networks), and (D) Cisco's own district‑court roster for completeness.

A. Petitioner ("plaintiff‑side") counsel in IPR2025‑01303 — Desmarais LLP

The petitioner's power of attorney appoints practitioners at Customer No. 132,593, all at Desmarais LLP, 230 Park Ave, New York, NY 10169 (Tel. 212‑351‑3400). The Board's Paper 14 caption lists only Cho and Thorne for petitioner; the fuller team appears in the petitions' mandatory notices (37 C.F.R. § 42.8(b)(3)) for the related IPRs against the same patent family (e.g., the ’243 petition at Petition No. 1558230).

Service email for the matter: Cisco-DynamicMesh-IPR@desmaraisllp.com

Sources: PTAB Paper 14 (Director Review order) ("FOR PETITIONER: Taeg Sang Cho Ryan Thorne DESMARAIS LLP"); petition mandatory notices, Petition No. 1558230.

Note: I could not independently pull up a firm bio sheet for each Desmarais attorney before hitting my research limit, so the "relevant experience" line is limited to what the docket itself shows (that they are the standing Cisco trial team on this MeshDynamics campaign). I have not fabricated case histories.

B. "Unified Patents" — no counsel found

Because the metadata lists Unified Patents as the plaintiff and the task asks for its counsel, I searched specifically for "Unified Patents" "Dynamic Mesh Networks" IPR2025-01303. The only result was the same Cisco‑captioned Paper 14. I found no Unified Patents appearance, power of attorney, or counsel of record in this proceeding. Unified Patents is a frequent IPR filer, but on the record before me it is not a party here. If the metadata is correct that Unified Patents is involved, the counsel would not appear on the visible IPR2025‑01303 docket — I cannot name them without a source, and I will not invent them.

---

C. Plaintiff‑side counsel in the actual district‑court infringement suits — Dynamic Mesh Networks (MeshDynamics)

In the parallel infringement litigation, the plaintiff is Dynamic Mesh Networks, Inc. d/b/a MeshDynamics, which asserted the ’537 and related daCosta patents against Cisco in the E.D. Tex. (Nos. 2:25‑cv‑00472, ‑00606, ‑00781, ‑00783) and faced Cisco's mirror‑image DJ action in N.D. Cal. (3:25‑cv‑06441). Plaintiff's counsel:

Sources: PACER Monitor docket, 2:25‑cv‑00783; Justia docket, 2:25‑cv‑00781; Justia docket, N.D. Cal. 3:25‑cv‑06441; PTAB service notice (Ainsworth signature).

Caveat on firm locations: I verified the Tyler, TX address for Wilson, Robertson & Vandeventer from the filing signature block. I did not verify Daignault Iyer LLP's office location from a primary source before reaching my limit — I am not asserting one.

D. Cisco's district‑court roster (the party adverse to the plaintiff above)

For completeness, on the Cisco side in the district‑court matters (Cisco as DJ plaintiff in N.D. Cal. 3:25‑cv‑06441 and defendant in the EDTX cases), the appearances include Michael R. Rhodes, Tamir Packin, Emily Nicole Weber, and Lindsey Miller (all Desmarais LLP), with Melissa Richards Smith (Gillam & Smith, LLP) appearing on the EDTX dockets. (Justia/PACER Monitor dockets cited above.)

Bottom line

• If "plaintiff" = the IPR petitioner: the operative counsel of record are Taeg Sang Cho (lead) and Ryan Thorne (back‑up), Desmarais LLP, New York — representing Cisco Systems, Inc., the real petitioner. There is no Unified Patents counsel on this docket.
• If "plaintiff" = the patent‑infringement plaintiff: that is Dynamic Mesh Networks (MeshDynamics), represented by Jennifer Parker Ainsworth (Wilson, Robertson & Vandeventer, Tyler, TX) plus the Daignault Iyer LLP team (Samay, Bernard, Hadi, Lepore, Phillips, Meroueh, Charkow) appearing pro hac vice.
• Material discrepancy to reconcile: the case metadata's identification of Unified Patents as the plaintiff/petitioner conflicts with the primary record, which shows Cisco Systems, Inc. as petitioner throughout IPR2025‑01303.

If you can tell me which "plaintiff" you intend — the IPR petitioner or the E.D. Tex. infringement plaintiff — I can drill deeper into that roster (bar admissions, prior Federal Circuit/PTAB track record, firm bios) and into any sealed or later‑appearing counsel.

I'll research counsel of record for the defendant/patent owner side, checking both the PTAB docket and the parallel district court tracks.

Now let me pin down the specific counsel for the defendant/patent-owner side across each venue.

Let me verify the E.D. Tex. dockets and the specific Dynamic Mesh appearances in each case.
