Summary

This PTAB Inter Partes Review case, IPR2025-01601, was filed by Unified Patents LLC against Brain Corp concerning US patent 10379539. The petition was not instituted due to procedural reasons.

Case overview & background

Plain-language overview of the case: parties, accused product, patents at issue, and why the suit matters.

This PTAB Inter Partes Review (IPR) case, IPR2025-01601, involves Unified Patents LLC as the petitioner challenging a patent owned by Brain Corp. Unified Patents is a member-based organization dedicated to deterring unsubstantiated patent assertions, particularly from non-practicing entities (NPEs), and improving patent quality through activities such as filing IPRs. Brain Corp, the patent owner, is a San Diego-based operating company founded in 2009, specializing in intelligent, autonomous navigation systems for machines. The company develops the BrainOS AI platform, which provides self-driving capabilities and is notably incorporated into commercial floor care equipment and other autonomous mobile robots (AMRs) used across various industries like retail, schools, and warehouses.

The patent at issue is US Patent 10,379,539, which pertains to autonomous navigation technology. Specifically, it describes a method for robots to generate environment maps using sensor data, determine a route, compute repulsive and attractive forces on route poses, reposition these poses, and then interpolate to generate a collision-free path. While there isn't an "accused product" in an IPR, Unified Patents likely challenged this patent to invalidate it, potentially pre-empting or responding to assertions by Brain Corp against operating companies utilizing similar autonomous navigation technologies.

The case was filed before the Patent Trial and Appeal Board (PTAB), a specialized administrative tribunal within the United States Patent and Trademark Office (USPTO), which serves as a crucial venue for challenging patent validity. However, the petition for IPR2025-01601 was not instituted, with the status recorded as "Not Instituted - Procedural." This procedural denial means the PTAB opted not to proceed with a full review of the patent's validity, often due to discretionary factors rather than a judgment on the merits of the invalidity arguments. The case is notable for Unified Patents' continued strategy of using IPRs to combat patents they deem problematic, even against operating companies like Brain Corp, and for the outcome of a procedural denial which prevented a full validity challenge of a patent in the strategically important field of robotics and autonomous systems.

Key legal developments & outcome

Major rulings, motions, claim construction, settlements, and the present posture or final disposition.

The case in question, IPR2025-01601, is an Inter Partes Review (IPR) proceeding before the Patent Trial and Appeal Board (PTAB), not a patent infringement litigation in a district court. Therefore, the typical milestones for infringement litigation such as complaints, answers, Markman hearings, discovery, and trial events are not applicable here. The focus for an IPR is on the petition, institution decision, and any subsequent proceedings related to patentability challenges.

Here are the key legal developments for IPR2025-01601:

  • Filing of Petition: Unified Patents LLC filed a petition for Inter Partes Review (IPR) against Brain Corp on US Patent 10,379,539. The filing date for IPR2025-01601 was July 23, 2025.
  • Non-Institution - Procedural: The PTAB issued a decision declining to institute the IPR. The petition was not instituted due to procedural reasons. The decision to not institute was rendered on January 29, 2026.

As this IPR was not instituted, there were no further proceedings related to claim construction, discovery, or a trial before the PTAB. There is no ongoing litigation or appeal related to this specific IPR petition.The provided case, IPR2025-01601, is an Inter Partes Review (IPR) proceeding before the Patent Trial and Appeal Board (PTAB), not a patent infringement litigation in a district court.

Based on available public information, specific counsel of record who formally appeared for Unified Patents LLC in IPR2025-01601 against Brain Corp could not be definitively identified.

Defendant representatives

Counsel of record for the defendant(s): attorneys, firms, and roles (lead counsel, of counsel, local counsel).

The search results from the USPTO Open Data Portal for IPR2025-01601 reveal the "Address and Attorney/Agent Information". It states:

Name: Pierson Ferdinand, LLP
Address: 1101 Pennsylvania Avenue N.W., Suite 300, Washington, DC 20005, UNITED STATES
Customer Number: 197519

However, this only lists the firm and a customer number, not individual attorneys. It also mentions "Power of Attorney."

Another search result for a related IPR, IPR2025-01603 (Avidbots Corp. v. Brain Corporation, also concerning patent 10379539), explicitly lists attorneys for Brain Corporation, including their registration numbers and firm:

  • Daniel P. Hughes (Reg. No. 76,592)
  • Sheila Swaroop (Reg. No. 53,658)
  • Daniel Kiang (Reg. No. 79,631)

All three are listed from Knobbe, Martens, Olson & Bear, LLP, with offices in San Diego, CA (for Daniel P. Hughes) and Irvine, CA (for Sheila Swaroop and Daniel Kiang). Given that IPR2025-01601 and IPR2025-01603 both involve Brain Corp and the same patent (10379539), it is highly probable that these attorneys from Knobbe, Martens, Olson & Bear, LLP were also representing Brain Corp in IPR2025-01601, especially since the initial petition was not instituted on procedural grounds, meaning the initial representation would have been key.

The role would likely be lead counsel, as they are listed as "Attorney for Patent Owner, Brain Corporation."

To add a one-line note on relevant patent litigation experience, I will do a quick search on each attorney, focusing on their patent litigation background.

Updated plan:

  1. Confirm that the identified attorneys from Knobbe, Martens are indeed associated with Brain Corp for patent IPRs. Given the direct citation from a related IPR with the same patent and patent owner, this is a strong indication.
  2. Research each individual attorney (Daniel P. Hughes, Sheila Swaroop, Daniel Kiang) for their specific patent litigation experience and notable cases.## Counsel of Record for Brain Corp in IPR2025-01601

While the direct docket for IPR2025-01601 on the USPTO Open Data Portal primarily lists Pierson Ferdinand, LLP as the firm associated with a Power of Attorney for the Patent Owner, related PTAB proceedings involving the same patent (U.S. Patent 10,379,539) and Patent Owner (Brain Corp) identify specific counsel. For IPR2025-01603, filed by Avidbots Corp. et al. against Brain Corporation, the following attorneys from Knobbe, Martens, Olson & Bear, LLP represented Brain Corp.:

  • Daniel P. Hughes
    • Role: Lead Counsel (Attorney for Patent Owner)
