Is there a word limit for the statement in the patent opinion statement?

No, the opinions stated in the patent opinion statement are all written according to your own opinions, and there is no word limit until you are satisfied. Patents are generally documents issued by government agencies or regional organizations representing several countries according to their applications. This kind of document records the contents of the invention and creation, and in a certain period of time, it has produced such a legal state that the patented invention and creation can only be implemented by others with the permission of the patentee. In China, there are three kinds of patents: inventions, utility models and designs.
