Sideman & Bancroft’s Guy Chambers Fends Off All Four IPR Challenges to f’real Foods Patent Portfolio

November 2017

Sideman & Bancroft’s Guy Chambers has successfully defended f’real Foods Inc. (“f’real”) against all four Inter Partes Review (“IPR”) challenges filed by Hamilton Beach Brands, Inc. (“Hamilton Beach”) against f’real’s self-cleaning blender patent portfolio.

Mr. Chambers, on behalf of f’real, an Emeryville, CA-based subsidiary of Rich Products Corporation, initially filed a patent enforcement action in Delaware District Court in October 2014 to stop Hamilton Beach from unfairly competing against f’real by copying f’real’s patented self-cleaning blender technology. In response, Hamilton Beach filed four IPR petitions with the U.S. Patent and Trademark Office (“USPTO”) against f’real’s self-cleaning blender patent portfolio.

To quickly blunt the impact of Hamilton Beach’s petitions, Mr. Chambers and f’real filed preliminary responses to all four IPR petitions explaining why f’real’s self-cleaning blender inventions were patentably different from the prior technologies relied upon by Hamilton Beach. The USPTO summarily denied three of Hamilton Beach’s four petitions in its initial decisions. For the fourth petition, it determined that a full evidentiary hearing was necessary before rendering a final decision. The evidentiary hearing on the fourth petition was held in July 2017 and on November 7, 2017, the USPTO rendered its final written decision rejecting Hamilton Beach’s remaining petition regarding U.S. Patent No. 7,520,662. Defying the odds, Mr. Chambers and f’real were able to fend off all four IPR challenges to f’real’s self-cleaning blender patent portfolio.

Mr. Chambers was assisted in his representation of f’real in all four IPR proceedings by Timothy Bianchi of Schwegman Lundberg & Woessner, PA and Ellen Liu at Sideman & Bancroft.

The case is Hamilton Beach Brands, Inc. v. f’real Foods, LLC, Case IPR2016-01107, Paper 35 (U.S. Patent No. 7,520,662).
