According to Article 5 of the Patent Law, "no patent right shall be granted for inventions that violate laws, social morality or harm public interests". No patent right shall be granted to inventions and creations obtained or utilized in violation of laws and administrative regulations and completed by relying on genetic resources. "and the provisions of Article 25 of this Law:" No patent right shall be granted for the following items: (1) scientific discovery; (2) rules and methods of intellectual activities; (3) Methods of diagnosis and treatment of diseases; (4) Species of animals and plants; (5) substances obtained by nuclear transformation; (six) the design of the pattern, color or the combination of the two. The production method of the products listed in Item (4) of the preceding paragraph may be granted a patent right in accordance with the provisions of this Law. The definition of "PatentRight", referred to as "patent" for short, is the exclusive right to exploit a specific invention within a certain period of time, which is a kind of intellectual property. China promulgated the Patent Law on 1984, and the detailed rules for its implementation on 1985, which made specific provisions on related matters. The word patent comes from Latin Litteraepatentes, which means open letters or open documents. It is a certificate used by medieval monarchs to issue certain privileges, and later refers to the exclusive right certificate signed by the British king himself. Patents are the largest source of technical information in the world. According to empirical statistical analysis, patents contain 90%-95% of the global scientific and technological information. The nature of natural patent right is mainly reflected in three aspects: exclusivity, timeliness and regionality. The exclusivity of patent right is also called exclusivity or exclusivity. The patentee enjoys exclusive or exclusive rights to the patent he owns, and no one may use it without his permission or under special circumstances stipulated by law, otherwise it will constitute infringement. This is one of the most important legal features of patent rights (intellectual property rights). The temporality of patent right means that the protection of the patentee by law is not infinite, but limited. After this period, it will no longer be protected, and the patent right will immediately become the wealth of mankind and anyone can use it. The regionality of patent right means that any patent right can only be produced in a certain area and protected by law. This is another important legal feature different from tangible property. According to this feature, the patent right obtained according to the laws of a country is only protected by law in that country, but not in other countries, unless there is a bilateral patent (intellectual property) protection agreement between the two countries, or * * * participates in an international convention on patent protection (intellectual property). According to the above provisions, the cases and matters in which the patent right is not granted mainly include: 1. Inventions and creations that violate the law should be strictly limited to "laws enacted by the National People's Congress and its Standing Committee". An invention that violates the law means that the purpose of the invention itself is contrary to the law. Such as counterfeit money equipment, can not be granted a patent right. If the purpose is not illegal and the illegal use violates the law, it is not an invention that violates the law. Such as poison used for medical purpose. 2. Inventions and creations that violate social morality, such as designs with obscene pictures. 3. Inventions and creations that hinder public interests * * * 4. Inventions and creations that obtain or use genetic resources in violation of laws and administrative regulations and rely on the genetic resources refer to any material that contains genetic functional units and has actual or potential value and is taken from people, animals, plants or tiny objects. This requires that inventions that rely on this genetic resource should be legally obtained and used, and the source should be stated when applying for a patent. 5. Scientific discovery is the discovery and understanding of the unknown things that exist objectively in nature. 6. Rules and methods of intellectual activities such as speed algorithm and competition rules. 7. Diagnosis and treatment methods of diseases, such as MRI diagnosis, acupuncture and massage therapy. 8. Animal and plant varieties can be protected through the Regulations on New Plant Varieties. The method of producing various animals and plants can be patented. In addition, micro-products and their production methods can also be granted patents. 9. 10 materials obtained by nuclear transformation, and designs that mainly mark the patterns and colors of plane printed matter or their combination, such as bottle stickers. Mainly protected by trademark law and copyright law.
