Kenyon successfully represented Photocure at the district court level in connection with Photocure's application for a patent term extension. Photocure applied for the extension on the basis of FDA approval of its Metvixia drug product, which is used to treat a precursor to skin cancer. The PTO denied the request for extension. Judge Liam O'Grady of the US District Court of the Eastern District of Virginia adopted Photocure's interpretation of the statute, granted summary judgment in Photocure's favor, and ordered the PTO to grant a patent term extension to Photocure. Case number 1:08-cv-00718-LO-JFA (2009).
