In August 2021, the United States Federal Circuit Court of Appeals held in Omni Medsci vs. Apple Inc. that a university IP policy and employment agreement providing that patents developed by an employee “shall be the property of” the university does not present an automatic assignment of future patent rights, and therefore is not sufficient to effectuate the assignment of legal title to the university. This case is a reminder that proper assignment language in a contract must be utilized to effectuate the desired transfer of intellectual property, and without it, you may not own what you think you own.
