1. What is the priority of patent right? The so-called prior right to use the patent right means that the actor has manufactured the same product before the patent application date, used the same method or made necessary preparations for manufacturing and using the product, and continues to manufacture and use it only within the original scope. According to the provisions of the patent law, his behavior is not regarded as infringement.
Second, the conditions for the defense of the prior right to use the patent right
Lawyers can represent patent cases, but patent cases, especially infringement disputes, require higher professional knowledge, and most lawyers are legal professionals who don't understand technical problems, so they often can't get to the point in defense.
