1. The Patent Cooperation Treaty
The Patent Cooperation Treaty (PCT) is an international patent law treaty, which provides a unified procedure for filing patent applications to protect inventions in each of its contracting parties. The PCT does not provide for the grant of an "international patent", and the grant of patent is a prerogative of the Japan Patent Office.
