Revision of patent text

After the application for a patent for invention is submitted, it may be amended voluntarily at the same time as the request for substantive examination is made or within 3 months after entering the substantive examination stage, but such amendment cannot exceed the scope of the original submitted documents, otherwise the Patent Office will not accept it.

If you have submitted a patent application in China, you can submit a pct application to pct Office of China Patent Office within 12 months from the date of application, which can be in Chinese or English.

In addition, official fees such as pct application fee need to be submitted, which is about 6.5438+0.2 million yuan. If approved, the personal request fee will be reduced to about 4,000 yuan.

After the pct application is accepted, it enters the first phase of pct, that is, the international phase, which is mainly a legal process without substantive examination and authorization procedures.

After the international publication of pct and before the deadline (usually 30 months from the date of patent application in China), the applicant can enter the second phase of pct, that is, the national phase, according to the requirements of the applicant. Applicants can choose the country or region they need to enter, because in order to obtain patent protection abroad, they must enter the country for patent application and examination to obtain patent authorization. The laws and fees in different countries are different, but they are usually much more expensive than those in China, and involve a lot of translation costs, so you should be prepared.
