Patents

Is it necessary to inform the Japan Patent Office (JPO) when a company has succeeded to one or more patent application(s) and/or patent right(s) due to a company split or a merger? If yes, what is the procedure for doing that? Also, what document(s) is/are required?

The procedure if an application is pending at the JPO differs from the procedure if a patent has been registered, as is similar to when a patent application or patent rights has/have been transferred, as explained in the answer to question No. 8. Moreover, the procedure to be followed differs, depending on whether a company has been involved in a company split or in a merger. For more information about this matter, please contact us here.
