What is an invalid patent?

Declaration of invalidation of utility model: ① Before you apply, any country in the world has applied for a similar patent; Before you apply, the technology has entered the market, that is, the products made with this technology have already circulated in the market.

Generally, there are two kinds of invalid situations.

As long as there is no problem with the utility model patent application, if the technology can be realized, the patent office will issue a certificate. You can find a patent office to do a substantive search (the official fee is 2500, and the agency fee is almost 3500)

If it is invalid, you will not enjoy the exclusive right of the patent from beginning to end. This is an invalid patent.

All fees previously applied for are non-refundable.
