Of course, there are some high-quality patented technologies that have not been discovered by others. Therefore, in order to obtain high-quality patents, it is necessary to proceed from the essence and see how the patented technology expands. For some patented technologies, they are actually useless patents, so we should screen them well. You can know the details of patent technical specifications and claims through the search platform. Finally, there are three kinds of patented technologies in China, namely invention patents, utility model patents and design patents. Most of them know that invention patents are of high quality and value, which can be used as a way to identify patents. Of course, invention patents are not necessarily high-value patents, and some of them are low-quality patents, so it is the most standard to consider patent technology comprehensively.
