Patently Enabled June 2025 – Experimental Use and Preserving Patent Rights

The purpose of this monthly series Patently Enabled is to share simplified patent-related information to assist non-patent practitioners in making the best decisions when considering their intellectual property rights.

In the June edition of Patently Enabled, Day Pitney Associate Emily Ferriter Russo and Partner George Chaclas discuss the experimental use exception to the On Sale Bar under U.S. patent law. They explain how sales or public uses of an invention that occur before a patent application is filed can sometimes avoid invalidating the patent—if those activities were conducted for experimental purposes.

For any patent-related comments, questions or other inquiries, please contact patent attorneys Emily Ferriter Russo or George Chaclas.
