Patent classification
1, valid patent
Generally speaking, a valid patent refers to a patent that is still in a valid state after the patent application is authorized. In order to make the patent in a valid state, the patent right is still within the legal protection period, and the patentee also needs to pay the annual fee according to the regulations.
2. Invalid patent
After an application for a patent is authorized, it is called an invalid patent because it exceeds the statutory protection period, or because the patentee fails to pay the annual patent fee in time, or any individual or unit requests to declare the patent invalid, and it is determined by the Patent Reexamination Board and declared invalid. Invalid patents are no longer binding on the use of the technology involved.
The legal meaning of patent
A patent is an invention protected by legal norms. It is an invention-creation that applies to the national examination and approval authority for a patent and is granted the exclusive right to invent within a specified time after passing the examination according to law.
Patent right is an exclusive right with exclusivity. If a non-patentee wants to use the patented technology of others, he must obtain the consent or permission of the patentee according to law.
The patent right granted by a country according to its patent law is only valid within the jurisdiction of that country and is not binding on other countries. Foreign countries do not undertake the obligation to protect their patent rights. If an invention is patented only in China, then the patentee only enjoys exclusive rights or exclusive rights in China.
The legal protection of patent right has timeliness. The term of invention patent right in China is 20 years, and the term of utility model patent right and design patent right is 10 years, counting from the date of application.
The word "patent" comes from Latin "Litterae patentes", which means open letters or open documents, and is a proof used by medieval monarchs to grant certain privileges. There is no unified definition of the concept of "patent", and one of them is accepted by people and widely used in patent teaching materials in China: patent is the abbreviation of patent right.
It is a document issued by a patent agency according to an invention application. Such documents describe the content of the invention and create a legal state, that is, the patented invention can only be used (including manufacturing, use, sales and import, etc.). ) In general, the protection of patents is limited by time and region. China's patent law divides patents into three categories, namely invention, utility model and design.
The two basic characteristics of patent are "monopoly" and "openness", and the exchange of "openness" for "monopoly" is the most basic core of patent system, which represents two sides of rights and obligations respectively.
"Proprietary" refers to the exclusive right granted by law to a technology inventor for a period of time; "Openness" means that the technical inventor makes his technology public in exchange for the exclusive right granted by law, so that the public can obtain the relevant information of patented technology through normal channels.
