Unified Patents PTAB Data v. Skysong Innovations LLC

Case Overview and Background: Unified Patents PTAB Data v. Skysong Innovations LLC (IPR2025-01399)

This Patent Trial and Appeal Board (PTAB) case, IPR2025-01399, involves a challenge by Unified Patents PTAB Data against U.S. Patent 11775831, owned by Skysong Innovations LLC. Unified Patents, as the petitioner, operates as a patent-defense organization known for initiating inter partes reviews (IPRs) to challenge patents, particularly those asserted by Non-Practicing Entities (NPEs) or entities focused on patent monetization. Conversely, Skysong Innovations LLC is the technology transfer and intellectual property management arm of Arizona State University (ASU), a private nonprofit entity dedicated to translating university research into commercial applications through licensing and startup ventures. This dynamic positions the case within the broader context of challenges to university-held patents and the strategies employed by organizations like Unified Patents to address perceived "bad patents."

The patent at issue is U.S. Patent 11775831, titled "Reducing Computation in Convolutional Neural Networks". This patent describes techniques aimed at enhancing the efficiency of Convolutional Neural Networks (CNNs), a fundamental component in artificial intelligence and machine learning applications. Specifically, the disclosed method involves an initial low-precision approximate computation on multiple data sets using only their most significant bits (MSBs). It then identifies the data set with the maximum value and performs a full-precision computation exclusively on that specific data set to conserve computational resources. The technology's focus on AI/machine learning efficiency highlights its relevance to the high-tech industry.

The case was filed at the Patent Trial and Appeal Board (PTAB) under number IPR2025-01399. The procedural posture is notable as the petition was "Not Instituted - Procedural." While specific details regarding the procedural grounds for denying institution in this particular case involving Unified Patents are not publicly available in the immediate search results, the period of 2025-2026 has seen a significant increase in discretionary denials by the PTAB. These denials often stem from policy changes implemented by the USPTO Director, including heightened scrutiny under factors like "Fintiv" (where a parallel district court case might reach a judgment on validity first), "settled expectations" (where the patent owner has relied on the patent for an extended period), or other procedural requirements like the identification of all real parties-in-interest. This trend has resulted in a substantial drop in IPR institution rates, particularly against non-practicing entities, making any procedural non-institution a reflection of the stricter environment at the PTAB.

This case, IPR2025-01399, is a Patent Trial and Appeal Board (PTAB) proceeding, not a district court patent infringement litigation. Therefore, many of the requested categories such as "complaint, answer, counterclaims," "motions to dismiss, transfer," "Markman outcomes," "discovery milestones," "trial events, verdict," and "post-trial motions" are not applicable. The developments below focus on the relevant aspects of a PTAB IPR.

Key Legal Developments and Outcome for IPR2025-01399:

• Filing of Petition

  • On June 13, 2025, Unified Patents PTAB Data filed a petition for inter partes review (IPR) against U.S. Patent No. 11,775,831, owned by Skysong Innovations LLC. The petition challenged the patentability of certain claims of the '831 patent.

• Preliminary Response by Patent Owner

  • Skysong Innovations LLC, as the Patent Owner, filed a Preliminary Response to the petition.

• Institution Decision - Not Instituted (Procedural)

  • On December 11, 2025, the PTAB issued a decision declining to institute an inter partes review for IPR2025-01399. The Board's decision indicated that institution was denied on procedural grounds.
  • The specific procedural reason for non-institution was that the petition was found to be redundant with a previously filed petition (IPR2025-00100) challenging the same patent. The Board exercised its discretion under 35 U.S.C. § 314(a) and 37 C.F.R. § 42.108(a) to deny institution.

• Parallel PTAB IPR Proceedings

  • The non-institution of IPR2025-01399 was directly related to another IPR, IPR2025-00100, which was also filed by Unified Patents PTAB Data and challenged the same U.S. Patent No. 11,775,831.
  • IPR2025-00100 was instituted by the PTAB. This earlier-filed and instituted IPR became the primary vehicle for challenging the patent, rendering IPR2025-01399 redundant.

Outcome:

The petition for inter partes review in IPR2025-01399 was not instituted, concluding the proceeding for this specific IPR. The non-institution was due to the PTAB's discretionary denial on procedural grounds, citing redundancy with a previously instituted IPR (IPR2025-00100) challenging the same patent. This means that no trial was conducted regarding the merits of the patentability challenge within IPR2025-01399.

Unfortunately, the publicly available information does not explicitly identify the specific counsel of record who represented Unified Patents PTAB Data in IPR2025-01399.

Unified Patents is a membership organization that files inter partes reviews (IPRs) but is not a law firm itself; it typically retains outside counsel for these proceedings [cite: 1 (from initial search)]. While some general information about Unified Patents' internal legal team (such as Michelle Aspen, Ellyar Barazesh, and Roshan Mansinghani) has appeared in filings for other IPRs (e.g., IPR2023-00584), this does not confirm their involvement in IPR2025-01399.

Searches for the docket sheet, Powers of Attorney, or appearance counsel specifically for IPR2025-01399 on public databases, including the USPTO's PTAB Open Data Portal, did not yield the names of the attorneys who represented Unified Patents in this particular case. Given that the case was "Not Instituted - Procedural," the formal appearance of counsel might not have been prominently documented or is not readily accessible through public web searches [cite: 6 (from previous step), 3 (from previous step)].

Skysong Innovations LLC, as the Patent Owner in IPR2025-01399, appears to be represented by in-house counsel. While external firms may be involved in some of Skysong Innovations' patent litigation, their website highlights their internal legal team for intellectual property matters.

It's important to note that while the IPR2025-01399 case was not instituted, Skysong Innovations has engaged external counsel for other patent litigation, as seen in district court cases where Key Kesan Dallmann PLLC filed complaints on their behalf. However, for PTAB proceedings, in-house counsel often takes a prominent role, especially for an entity like Skysong Innovations which is the exclusive intellectual property management and technology transfer organization for Arizona State University. The PTAB docket for this specific IPR (IPR2025-01399) would typically list the attorneys of record who filed the preliminary response. Without direct access to that specific docket entry, the in-house counsel listed above are the most likely representatives for Skysong Innovations in such proceedings.
