Writing cycle: the first draft can be completed in four weeks.
The processing period of invention patents is about 1-2.5 years, including the substantive examination stage. Compared with the preliminary examination, it has more contents, stricter requirements and longer time. Higher standards have been set in terms of novelty, creativity and practicality, openness of instructions, and whether the writing of claims meets the requirements. If you need to shorten the time, you can choose the priority audit service.
