EPO adopts stricter requirements for recording assignments
The European Patent Office has adopted stricter requirements for recording the assignment of European patents and patent applications.
Whereas previously assignments signed by only the assignor were acceptable provided the request to record the assignment was filed by the assignee, the European Patent Office will now require all assignments to be signed by both the assignor and the assignee.
Assignments prepared by Adamson Jones will always ask for the signatures of both the assignor and the assignee. However, this change may be relevant in cases where the parties have prepared the assignment themselves, and hence we would recommend that parties seek our advice before executing any assignments of European patents or patent applications to ensure that they will be accepted by the European Patent Office.
