Summary

This is an Inter Partes Review (IPR) challenging US patent 10697398, which has been instituted and is currently pending.

Case overview & background

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

This Inter Partes Review (IPR) challenges the validity of U.S. Patent No. 10,697,398. The Petitioners are Harbor Freight Tools USA, Inc., Generac Power Systems, Inc., and MWE Investments, LLC. The Patent Owner is Champion Power Equipment, Inc.. All parties appear to be operating companies involved in equipment or tools. Champion Power Equipment, Inc. is known for manufacturing generators, inverters, log splitters, and other power equipment. Harbor Freight Tools USA, Inc. is a retailer of tools and equipment, while Generac Power Systems, Inc. manufactures power generation products. MWE Investments, LLC's specific business in relation to this patent is not immediately clear from the IPR filing, but given the co-petitioners, it likely relates to similar industries.

The asserted patent, U.S. Patent No. 10,697,398, is titled "Power system with remote control." A quick technical sketch suggests the patent covers aspects of power systems that can be operated or controlled remotely. The specific accused products or services that led to this IPR are not detailed in the IPR filing itself, as IPRs focus on patentability. However, the involvement of these particular Petitioners suggests the patent owner, Champion Power Equipment, Inc., may have asserted this patent in district court litigation against products offered by Harbor Freight and Generac, likely relating to generators or power equipment with remote start or control features.

This IPR, IPR2025-01271, is currently pending before the Patent Trial and Appeal Board (PTAB) and has been instituted. The PTAB is an administrative body within the U.S. Patent and Trademark Office (USPTO) that conducts trials regarding the patentability of claims in an issued patent. The institution of an IPR signifies that the PTAB has determined there is a reasonable likelihood that at least one of the challenged claims is unpatentable. While the prompt states the status as "Instituted," the specific Board members or division are not typically listed in the initial IPR overview but would be found in the institution decision. The PTAB venue is significant as it provides an alternative forum to district courts for challenging patent validity, often seen as a more cost-effective and faster route for accused infringers. The case is notable as it involves multiple operating companies challenging a competitor's patent, suggesting active competition and potential infringement disputes in the power equipment industry.

III. Effect of IPR on Litigation

The institution of IPR2025-01271, challenging US Patent 10,697,398, provides the petitioners (Harbor Freight, Generac, and MWE Investments) with an administrative avenue to challenge the validity of the patent outside of district court. While the IPR is pending, it is common for parties in parallel district court litigations to file motions to stay the infringement proceedings. No specific docket entries regarding motions to stay pending the outcome of IPR2025-01271 have been found in the provided search results for the district court cases as of the current date. However, such motions are a likely strategic development.

Plaintiff representatives

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

Unfortunately, I cannot directly access PACER or proprietary legal databases. Therefore, I cannot definitively identify the counsel of record and their specific roles (lead counsel, of counsel, local counsel, in-house) for IPR2025-01271 at this time. Filings like the Petition for Inter Partes Review or subsequent docket entries would typically contain this information. Without direct access to these documents, it's impossible to provide the requested details about the attorneys, their firms, office locations, or specific patent litigation experience.

Therefore, I must explicitly state that the counsel information is not available through open web searches for this specific IPR.
