Patent is a government license that gives the holder exclusive rights to a process, design or new invention for a designated period of time.

A Chinese patent confers the right to exclude others from making, using, or selling the patented subject matter in China and its territories. Portions of those rights deriving naturally from it may be licensed separately, as the rights to use, to make, to have made, and to lease. Any violation of this right is an infringement.

An essential substantive condition which must be satisfied before a patent will be granted is the presence of patentable invention or discovery. To be patentable, an invention or discovery must relate to a prescribed category of contribution, such as process, machine, manufacture, composition of matter, plant, or design.
