The cycle for granting an invention patent is generally two to three years because it has to go through two stages: preliminary examination and substantive examination.
The way to speed up the examination is usually to require early disclosure and to request substantive examination and pay substantive examination fees at the same time as the application. If the invention has significant benefits to the country, you can also request early review and pay a 1,400 yuan fee to expedite the review, but the speed may not be much faster.
Whether an invention can pass examination and shorten the examination time is affected by many factors. The first is the invention itself. If it has high novelty and creativity, it is easier to obtain authorization. The second is the writing quality of the application documents. If it is well written, properly protected and does not require too many modifications, it will be easier to obtain authorization. The third is process control. Since there are many time constraints in the patent application process, each level must be completed in the shortest time, and problems such as rejection due to missed time must be avoided. Process control is very important. of. Finally, it is luck. If the examiner goes out for further study or takes maternity leave, it is normal for an application to take 4-5 years.
Among the invention patents I have represented, the fastest one was authorized 11.5 months after application, and some were authorized in 1 and a half years. Good luck!
