What are the common problems in patent trading? With the strengthening of China's awareness of protection, more and more small and medium-sized enterprises realize that the competition in the market is actually the competition of scientific and technological innovation of enterprises and the competition of intellectual property rights. Although the importance of intellectual property rights is recognized, many small and medium-sized enterprises are confused about the achievements made in purchasing patented technology. Because they don't understand the value of patents, they don't know how to explore technology through patents. So what are the common problems in patent trading? What are the common problems in patent trading? 1, select the appropriate agency and patent value appraisal company. If an enterprise wants to buy a patent, it can buy it through a professional intellectual property agency and entrust a patent value evaluation company to stop the pre-evaluation. Because these companies have rich experience in judging the content and value of patents. Moreover, these companies are operating with records and have good volatility. 2. Think about the ineffectiveness and volatility of the patent itself. Before signing the contract, you must verify the latest legal form of the patent. Patents usually have an invalid period, and the legal form of patents can change with time. When signing a patent purchase contract, it is necessary to evaluate the fluctuation of patent rights, otherwise there will be the risk of being effectively destroyed in the future. 3. It depends on whether the patent is a central patent or a core patent. In a complex sense, the core patent is absolutely different from the central patent, and its research and improvement are based on the central patent. The value of the two is quite different. The core patent and the central patent can constitute an interspersed license, which unilaterally uses the other party's patent without suing the other party for patent infringement. It depends on the scope of patent protection. The scope of patent protection refers to the scope of creation and invention touched by the legal effect of patent right. The scope of protection for the creation or application of a new patent right shall be subject to the content of its rights and interests, and the rights and interests may be explained by using the specification and attached drawings. The scope of protection of the patent right of design shall be subject to the patented product of design shown in pictures or photographs. The legal documents that determine the scope of patent protection are claims, statements, photographs or pictures of designs. 5, the introduction of patents need to choose a suitable introduction method for enterprises. There are many ways to sell patents. Such as exclusive license, exclusive license, general license, complete sale, etc. Each contract type has different efficiency and characteristics, and enterprises should make appropriate choices according to its actual use and industry characteristics. For example, an enterprise needs a patent license when the demand for patent purchase is high, and it must be an exclusive license for more than five years, and it must be authorized in the last three years.
