You can use this document to transfer the rights to your patent application to your company, or another entity or person, well before the patent application is approved.
You can also use a Patent Application Assignment to change the name on a pending patent.
The owner of a patent may transfer, give or sell to another person the owner's interest in the patent.
This type of agreement/gift is called an assignment, and the person who receives the owner's interest is called an assignee.
Further, if your client would like to enforce the patent rights, any change of ownership first must be recorded at the JPO.
We recommend an assignment be recorded at your earliest convenience, since sometimes the original assignment document executed between the parties is insufficient to file with the JPO and we need to obtain a newly signed assignment for recordation purpose.
There is no set time frame for recordation of an assignment.
However, if during prosecution the applicant wishes to file an appeal, a Power of Attorney must be submitted and in order to submit the power of attorney it is necessary to record the assignment.
For issued patents, the JPO will issue a Notification of Completion of Patent Registration when a transfer of the patent right has been registered at the JPO.
Such a confirmation document will not be issued for patent applications. If an assignment document has been filed with the JPO, anyone will be able to gain access to the information by obtaining the file history through the JPO website or the file wrapper from the JPO database.
