Why it matters

The Federal Circuit reversed a jury verdict in International Medical Devices, Inc. v. Cornell, holding that cosmetic penile implant designs alleged as trade secrets were not protectable under California law because they had been disclosed in publicly available patents. The court found the designs "generally known" and therefore ineligible for trade secret status. A fourth alleged secret—a list of surgical instruments sent via email without confidentiality markings—also failed protection due to insufficient secrecy measures. The panel reversed findings of trade secret misappropriation, breach of contract under the parties' nondisclosure agreement, and improper inventorship claims related to two Penuma patents. The court affirmed $1 million in statutory damages for trademark counterfeiting.

The case involved Dr. James Elist, a Beverly Hills urologist and Penuma developer, and his company International Medical Devices suing Joshua Cornell over alleged misappropriation of penile implant technology. The Federal Circuit applied California's Uniform Trade Secrets Act, emphasizing that patent disclosures irrevocably place information into the public domain. Oral arguments occurred March 5, 2026, before Judges Dyk, Taranto, and Reyna, with the decision issued approximately April 30, 2026.

The decision reinforces a critical boundary in IP strategy: inventors cannot pursue trade secret protection for information already disclosed through patent applications. For medtech and other patent-heavy industries, the ruling clarifies that public disclosures forfeit any claim to confidentiality, regardless of subsequent efforts to restrict access. Firms should audit whether dual protection strategies—pursuing both patents and trade secrets on the same subject matter—create vulnerabilities in litigation.
