Can the patentee implement it by himself?

Yes, the implementation of the patent right is the use of the patented invention. The implementation of patent rights has a wide range of meanings, including manufacturing, selling, using and importing patented products, and storing related patented products for sale or use or using patented methods. The exclusive right to use includes three aspects: the patentee implements his own patent; The patentee licenses others to exploit his patent and collects royalties; The patentee forbids others to exploit his patent. After obtaining a patent, the patentee has the exclusive right to exploit the patent. Implementing a patent is not only the right of the patentee, but also the obligation of the patentee. If the patent right is granted for 3 years, the patent itself and others are not allowed to exploit the patent, and the Patent Office will issue a compulsory license according to the application of others.
