Regionality: According to the principle of patent independence stipulated in the Paris Convention, the regionality of patent right means that the patent right granted by a country according to its own patent law is only valid within its jurisdiction and is not binding on other countries. Foreign countries do not undertake the obligation to protect their patents, but only obtain the patent right for an invention in China, so the patentee only enjoys the patent right or exclusive right in China. If someone produces, uses or sells the invention in other countries and regions, it is not an infringement. It is very meaningful to understand the regional characteristics of patent rights. In this way, if units or individuals in China develop inventions with international market prospects, they should not only apply for domestic patents in time, but also seize the opportunity to apply for patents in other countries and regions with good market prospects, otherwise foreign markets will not be protected. Timeliness: the so-called temporality refers to all the exclusive rights granted by the patentee to his invention and creation, which are only valid within the time stipulated by law. After the expiration of the time limit, the patentee no longer enjoys the exclusive right to manufacture, use, sell, promise to sell and import his invention and creation. At this point, inventions protected by law have become public wealth of society, and any unit or individual can use them free of charge.
Duration: The patent laws of all countries clearly stipulate that the protection period of invention patents generally ranges from 10-20 years from the date of application; The term of utility model and design patent is 5- 10 years in most countries, while the term of protection of invention patent, utility model patent and design patent in China is 20 years from the date of filing, 10 years and 10 years respectively.
Invisibility: Patent right is intangible, and many people often regard this feature of patent right as the object of protection-the technology protected by patent right, in fact, invisibility is the patent right itself. Otherwise, as far as a trademark is concerned, its object is a pattern, which is obviously not intangible.
