Extended data:

In our country, patent has two meanings:

1, the use of spoken language only refers to "exclusive possession". For example, "This is just my patent".

2. There are three confusing meanings in intellectual property rights, including:

First, the patent right refers to the patent right enjoyed by the patentee, that is, the state grants the patentee or his successor the exclusive right to use his invention and creation within a certain period of time, and the emphasis here is on rights. Patent right is an exclusive right with exclusivity. If a non-patentee wants to use the patented technology of others, he must obtain the authorization or permission of the patentee according to law.

Second, it refers to inventions protected by the patent law, that is, patented technology, which is a proprietary technology recognized by the state and protected according to law on the basis of publicity.

The "patent" here refers to the technology or scheme protected by national laws. The so-called proprietary technology is the technology with exclusive rights, which is a bigger concept, including patented technology and technical secrets. Some professional technologies that do not belong to patents and technical secrets are meaningful only in some technical service contracts).

A patent is an invention protected by legal norms. It is an invention that submits a patent application to the national examination and approval authority, and after passing the examination according to law, it grants the patent applicant the exclusive right to enjoy the invention within the time specified by the state, and needs to pay an annual fee regularly to maintain the protection state.

Third, it refers to the patent certificate issued by the Patent Office to confirm that the applicant enjoys the patent right for his invention-creation, or refers to the patent document that records the content of the invention-creation, and refers to the specific material document.
