Panel: Judges Taranto, Chen, and Stoll, with Judge Taranto writing the opinion You should read this case if: you have a dispute about whether an employment contract assigned ownership of an invention Consider this scenario: an employment contract requires an employee to assign to the employer the entire right to any IP that the employee conceives, develops or creates during the term of employment. Does that provision give the employer co-ownership rights in an invention admittedly conceived after employment ends if the former employee based the invention at least in part on ideas allegedly developed during employment? The Federal Circuit said no in this week’s case of the week, interpreting an employment agreement like the above under California law.
