How to avoid being cheated when applying for a patent?

1. Distinguish patent categories, and don't apply blindly. According to the Patent Law promulgated by the state, it can be divided into invention patents, utility model patents and appearance patents. For example, the technical scheme that can apply for a patent for invention is required to apply for a patent for utility model. There are also applications for invention patents with plans to improve the shape and appearance. 2, mistakenly believe that a patent certificate is an effective patent right < P >. In China, China National Intellectual Property Administration's requirements for creative examination of utility models are lower than that of inventions, but there is no substantive examination of design patents. Even if someone has applied for a very similar patent on the same technical scheme before you apply, your application may still be approved. If no one raises an objection, your patent right will remain. Once someone declares your patent invalid, your patent will be almost 1% invalid, which means that you have not obtained a valid patent right.
