Can our company ask the other party to issue an intellectual property invoice when purchasing a patent?
What is it used for? I haven't experienced this process. There are two suggestions. 1 is to pay the patent fee for next year, so that you can have a new invoice, which can be used to prove the validity of the patent. Make a patent register. It was originally 20 yuan from Qian Qi. Now I don't know if there will be a charge, but it can also be used to prove the validity of your patent.
