Documents and materials required for application: (1) Application documents: including specification, claims, drawings of specification, abstract and drawings of abstract; (2) Application information: Chinese and English names, addresses and postal codes of the applicant and inventor, country of application, contact person, etc. ; (3) priority information (4) power of attorney; Second, the way of Patent Cooperation Treaty (PCT): PCT is the English abbreviation of Patent Cooperation Treaty, which is an international treaty related to patent application. According to the provisions of the PCT, the applicant can submit an international application through the PCT channel and designate to apply for a patent in almost all countries in the world, that is, to file a PCT international application in China National Intellectual Property Administration, China within 12 months from the filing date (priority date) of the earlier application in China, and to file an entry application in the US Intellectual Property Office within 30 months from the priority date. It can be seen that every country has different regulations on patent protection, and patent protection between countries is more severe.
