Second, the US patent application channels and processes There are three ways to apply for a patent in the United States: 1. Apply for a patent directly to the United States (confidential examination needs to be conducted in China Patent Office in advance, and you can apply for a patent directly to the United States after the confidential examination is passed); 2. Apply for a patent in the United States through the Paris Convention (the priority is only 12 months); 3. Apply for a patent in the United States through the PCT Patent Cooperation Treaty (priority can reach 30 months). U.S. Patent Application Process (1) After the U.S. patent application is submitted, it will take about two months to get the acceptance notice. After obtaining the application, there will be a review result in about one and a half years, including patent authorization and patent rejection. The applicant usually has two chances to reply to the notice of rejection issued by the US Patent Office, and the exception may be three or four times. The first refutation notice is called "the first OA" and the last notice is called "the last OA". U.S. Patent Application Process (2) If OA still fails in the end, the official will issue a constructive reply notice, that is, a "defensive response". This kind of notice does not need to be defended, and its function is similar to the notice of rejection in China. At this time, we can ask for further review (RCE), which is different from defense. When RCE is put forward, we can modify this idea. American patent application process (3) Finally, once the application is approved, the applicant must pay the license fee before receiving the patent certificate about 3 ~ 4 months after the approval date; Failing to pay the license fee within the time limit shall be deemed as giving up the application.
