According to the examination process for invention patents, invention patent applications must first be made public within 18 months from the date of application, and then the applicant must submit a request for substantive examination within 3 years from the date of application. After substantive examination, the patent right can be granted only if the patent administration department of the State Council finds no inconsistency with the provisions of the Patent Law or the Implementing Rules of the Patent Law. In the patent application process, the editor mentioned that the application time is different for different patent types. So what about the time it takes for different patent applications? 1. Design patent application (6 months to 8 months) To apply for a design patent, you need to prepare six-sided appearance views of the product, fill in the "Design Patent Application Form" together with a brief description of the design, and submit it to the National Knowledge Infrastructure Submit application documents to the Property Rights Office. After submitting the application, you can get the "Patent Acceptance Notice" in about a week; the Intellectual Property Office will issue the "Notice of Grant of Design Patent Rights" and "Notice of Registration Procedures" in about six months; pay the patent registration fee and annual fee. After that, the certificate will be issued in about two months. Therefore, design patent applications generally take 6 months to one year, but the specific time depends on the review status of the patent office. 2. Utility model patent (10 months to 1 year) Both utility model patents and invention patents need to write a request, claims, instructions and other patent application documents and submit them to the patent office. Among them, the invention patent application process is the most complicated. The Patent Law stipulates that invention patents are subject to substantive examination only after the application description is disclosed. Submitting an early disclosure statement is to enter substantive examination as soon as possible and shorten the patent application cycle. Therefore, if you need to shorten the application period, it is best to submit two documents, the "Request for Advance Disclosure Statement" and the "Request for Substantive Examination" at the same time when applying for an invention patent.
