If the patentee is himself (company), the patented product does not need special approval for listing, but the patented product must be correctly marked (or not marked); If the patentee is someone else (company), but has obtained permission from others, it is necessary to file a license contract with the State Information Bureau. When transferring the patent right, we should not only pay attention to signing the patent right transfer contract, but also pay attention to changing the description items, because the latter shall prevail after the patent right is changed. In addition, if the patented products are to be exported abroad, they need to apply for corresponding licenses.
