Unified Patents v. Comet Ml Inc

Unified Patents initiated an Inter Partes Review (IPR) against Comet ML Inc. concerning US Patent 11650968, which ultimately concluded in a settlement.

Unified Patents is a member-based organization dedicated to promoting innovation by mitigating the impact of non-practicing entity (NPE) patent assertions and challenging what it considers to be poor quality patents across various technology sectors, including through administrative patent review proceedings like IPRs. They operate independently of their members and aim to deter frivolous litigation by increasing the cost and risk for NPEs asserting invalid patents. Comet ML Inc. is a technology company specializing in an enterprise machine learning development platform. Their platform provides tools for data scientists and engineers to track, manage, optimize, and deploy machine learning models, offering capabilities such as ML experiment management, model production monitoring, and LLM observability for generative AI applications.

The patent at issue, US 11650968, is titled "Method and system for managing machine learning experiments." This IPR was filed at the Patent Trial and Appeal Board (PTAB), a specialized administrative court within the U.S. Patent and Trademark Office (USPTO), under case number IPR2025-01063. The PTAB provides a faster and often less costly forum for challenging the validity of patents compared to traditional district court litigation, making it a crucial venue for entities like Unified Patents in their efforts to clear the patent landscape of potentially invalid patents.

The case is notable given Unified Patents' active role in combating patent assertions by NPEs and its focus on improving patent quality. The involvement of Comet ML Inc. highlights the ongoing scrutiny and challenges in the rapidly evolving and economically significant field of artificial intelligence and machine learning, where the underlying technologies are foundational to many modern enterprise solutions. The settlement of the IPR indicates a resolution between the parties regarding the patentability of the challenged claims.

Despite extensive searching, specific public docket information detailing the legal developments and outcome for IPR2025-01063, Unified Patents v. Comet Ml Inc., regarding U.S. Patent 11650968, could not be located. While the case is noted as having "settled," the precise dates for key milestones such as the petition filing, institution decision, and settlement are not readily available through public web searches of court dockets, PTAB databases, or legal news outlets.

It is important to distinguish this patent IPR from a prominent trademark infringement case, Comet ML Inc. v. Perplexity AI Inc., No. 25-cv-4088 (N.D. Cal.), which commenced around May 2025 and involved a preliminary injunction and subsequent settlement by August 2025, with a trial originally set for February 2026. This trademark case pertains to the use of the "Comet" mark for AI-powered browsers and software, not patent 11650968.

Without specific docket entries for IPR2025-01063, a detailed chronological account of the IPR's progression, including filing dates, institution decisions, or specific settlement terms, cannot be provided. Unified Patents is an organization known for filing numerous inter partes review petitions, many of which result in procedural terminations, including settlements. However, specific details for this particular IPR remain unconfirmed in publicly accessible records.

The IPR case IPR2025-01063, filed by Unified Patents against Comet Ml Inc. regarding US patent 11650968, concluded in a settlement. Publicly available information, such as the Unified Patents portal, lists the case with a "Settlement" status. However, specific details about the counsel of record for Unified Patents in this particular IPR are not readily available through general web searches of PTAB dockets or Unified Patents' own public case lists, which often focus on outcomes and general statistics rather than detailed attorney listings for individual settled IPRs.

Unified Patents frequently works with external law firms for its IPRs, and also utilizes in-house counsel. For instance, in a different ex parte reexamination proceeding, Unified Patents was represented by Nick Apel and Eric Buresh of Erise IP, and by in-house counsel Jessica L.A. Marks and Michelle Aspen. However, without direct access to the docket for IPR2025-01063 or specific announcements related to this settlement, it is not possible to definitively identify the counsel of record for Unified Patents in this specific case.

Therefore, at this time, the counsel of record representing Unified Patents in IPR2025-01063 cannot be precisely identified from publicly available information.

The IPR case IPR2025-01063 between Unified Patents and Comet Ml Inc. concerning US Patent 11650968 concluded in a settlement. While specific counsel information for this particular IPR is not readily available through general web searches of PTAB dockets or Unified Patents' public case lists, a broader search for Comet ML Inc.'s legal representation in patent-related matters, particularly those involving AI and machine learning, yields some relevant information.

In a separate trademark infringement lawsuit, Comet ML Inc. v. Perplexity AI Inc., filed May 12, 2025, in the U.S. District Court for the Northern District of California, Comet ML Inc. is represented by:

• Eleanor M. Lackman (Lead Counsel)

  • Firm: Mitchell Silberberg & Knupp LLP
  • Office Location: New York, NY (based on typical firm practice, though specific office for this case is not detailed in the snippet)
  • Note: Lackman is also listed as co-chair of MSK's Trademark and Copyright practice, suggesting expertise in intellectual property litigation.

• Marissa B. Lewis (Counsel)

  • Firm: Mitchell Silberberg & Knupp LLP
  • Office Location: Not specified in the provided information.

It is important to note that representation in a trademark infringement case does not automatically confirm their involvement in a settled IPR. However, it indicates a likely relationship between Comet ML Inc. and Mitchell Silberberg & Knupp LLP for intellectual property matters. Without direct access to the sealed docket for IPR2025-01063, definitive identification of counsel of record for Comet Ml Inc. in that specific IPR remains elusive. PTAB settlement agreements are filed with the USPTO but can be treated as business confidential information at the request of a party.
