Nathaniel Luke Dilger

Nathaniel Luke Dilger is a Partner at One LLP, focusing his practice on intellectual property disputes, particularly patent infringement and trade secret misappropriation claims. With a background in mechanical engineering, he handles a wide array of technologies including semiconductor fabrication, internet-related technologies, opto-electronic devices, GSM mobile phone technologies, and biomedical devices. His practice also extends to the prosecution of patents before the U.S. Patent and Trademark Office (USPTO).

Based on tracked appearances, Mr. Dilger primarily represents plaintiffs in patent litigation, having appeared in three such cases and none on the defendant side. His broader career experience, however, shows a history of representing both plaintiffs and defendants in intellectual property litigation, including significant defense work in some cases.

A notable recent engagement includes representing FaceTec, Inc. as plaintiff in FaceTec, Inc. v. Jumio Corporation et al., concerning biometric liveness detection technology. In this matter, the U.S. Patent Trial and Appeal Board (PTAB) recently upheld the patentability of all four challenged claims relating to FaceTec's 3D liveness technology in inter partes reviews (IPRs) initiated by Jumio. Mr. Dilger also secured a complete victory for Polara Engineering in a patent infringement lawsuit regarding accessible pedestrian crosswalk systems, where a federal jury awarded full royalty damages. Additionally, he successfully defended a major international media company in a high-stakes litigation involving alleged piracy, resulting in a jury verdict that awarded minimal damages against his client, a win recognized as one of the Top Ten Defense Verdicts of 2008.

Mr. Dilger is experienced in post-grant proceedings, having handled numerous IPRs before the PTAB and argued one of the first IPR decisions before the Federal Circuit, which affirmed the patentability of his client's patent. He also co-authored an article on the effectiveness of the IPR process in Los Angeles Lawyer Magazine. He is admitted to the State Bars of California (1998) and Ohio, and practices before the U.S. Courts of Appeals for the Federal and Ninth Circuits, as well as multiple U.S. District Courts. He earned his J.D., cum laude, from Ohio State University College of Law in 1997.
