First, confirm whether the patent right is valid.
Second, search for patentee information.
Third, confirm whether the patent has been licensed and whether the license is still valid. If the patent rights involved have been licensed to a third party and the license is still valid, the transfer may affect the interests of the transferee.
Fourth, whether the patent has gone through or is going through the invalidation procedure.
Fifth, whether the patent has been preserved or pledged.
Sixth, confirm the deadline for paying the annual fee. If the annual fee deadline is approaching or needs to be paid during the transfer process, customers need to be reminded to clearly identify the party responsible for maintaining the validity of the patent rights to avoid late payment fees or rights invalidation due to overdue annual fees.
Sometimes the legal status updates on the Intellectual Property Office website are slightly lagging behind. You can check the time and type of notices sent by the Intellectual Property Office to help determine the current stage or status of the case. If the Intellectual Property Office issues a "Notice of Acceptance of Invalidation" to a third party that is not an agency or the patentee, then the patent is being requested to be invalidated by the third party.
The above is a brief introduction to the role of the patent process administrator in the agency change process.
