I understand that patent right is an "exclusive right". The patentee may prohibit anyone other than himself and his licensors from producing, selling or promising to sell the products covered by his patent right or using the methods covered by his patent right.
If you want to have the above rights, you must apply for a patent. Only when you apply for a patent can you use the patent right. Of course, if you apply, you don't have to authorize it. If you authorize it, you don't have to have the scope of protection you want, because patent examination is subject to legal examination.
Patents have many commercial uses, the most common of which is 1. You can prohibit your competitors from producing, selling or promising to sell products within the scope of patent protection, or prohibit your competitors from using patented processes. 2. By signing an "implementation license contract", some people are allowed to produce, sell or promise to sell products within the scope of patent protection in designated areas, or they are allowed to use methods protected by patent rights, so as to obtain a "license fee" and finally achieve the purpose of obtaining economic benefits. 3, the patent as intangible assets, production and operation in cooperation with others, or as a technology share. 4. Pledged loans as intangible assets. 5. Protect the patent right through tort litigation, and then obtain economic benefits. 6, by applying for some defensive patents, prevent yourself from becoming the defendant of patent infringement litigation.
All I can think of is the above functions, for reference only.
