What is an invention patent?

You can apply for a patent for utility model for things that are made of small things around you and are convenient to use. Applying for a new patent in China can be said to be 100% guaranteed authorization, because "utility model patent" will not be searched before authorization, which means that people in the patent office will not search your patent and guarantee that there is no similar application before. They will only look at whether your patent is innovative or not, so long as there is a little innovation, even "micro-innovation" can be authorized.

As for the "invention patent", the invention patent has passed a series of rigorous examination, especially the examination of novelty, creativity and practicality, including product invention and method invention. Because determining uniqueness before authorization is a strict search, it will take a long time and be difficult in general authorization. So "invention patent" can be understood as an idea that others have not applied for before. You should make sure that you have never applied. Therefore, before applying for a patent for invention, you'd better search for the patent and make a preliminary decision.

If it is a better idea, you can also consider applying for an invention patent and using a new patent at the same time, which is safer.
