How many ways are there in patent trading mode?

First, there are several ways of patent trading mode? 1, contract patent transaction Any patent transaction will be determined in the form of a contract. Contract patent trading refers to the way that the patent transferor and transferee independently conduct patent trading without going through the patent trading intermediary in accordance with the contract requirements set by the laws and regulations related to the contract. This type mainly includes patent technology transfer agreement, patent technology contracting agreement, patent technology consulting agreement, patent technology service agreement and patent technology shareholding agreement. Contract patent transaction is generally applicable to the case that the subject of patent transaction is simple and clear, but the subject of patent transaction is complex. 2. Auction-style patent transaction auction is a way of price competition with many bidders. As long as each bidder meets the purchasing power and corresponding conditions, he can participate in the auction, and after winning the highest price, he will have the opportunity to obtain the auction target. The process is relatively open and transparent, which helps to maximize the value of the auction target. 3. Bidding patent transactions Bidding patent transactions are mainly divided into two forms: open bidding and invitation bidding. Its basic process is that, according to the entrustment of the patent supply and demand sides and the requirements of relevant laws and regulations, bidding activities are organized by bidding trading institutions. Second, what is the particularity of patent trading? Patent transaction has the characteristics of tangible property and service transaction, and has a strong policy tendency. Moreover, with the trading of technical guidance, technical secrets and related equipment, and due to the characteristics of patents and other factors, patent trading contains the following remarkable particularities. 1, the particularity of the trading subject The patent trading subject is the right subject to be determined first in the process of patent trading, which mainly involves the qualification of the trading subject, that is, whether the subject has the qualification of trading rights. If the subject of patent trading is unqualified, or its subject qualification is flawed, it may directly lead to the invalidation of patent trading behavior. 2. Particularity of the transaction object The characteristics of the patent itself fundamentally determine the particularity of the patent transaction object. In addition to invisibility and legal monopoly, there are the following obvious contradictory features: (1) the contradiction between the permanence of patent transaction object information and the temporal and spatial validity of its legal effect. As a kind of knowledge information, patent technology can't be completely produced without historical connection, and it is "sustainable". However, the law limits the legal effect of patent right in time and space; (2) The contradiction between the certainty of the transaction object and the relative uncertainty of the protection scope of the object's own rights. The subject of patent transaction is based on a clear transaction object. However, due to the practical difficulties in defining the scope of patent protection, the scope of patent protection involving transactions is relatively uncertain; (3) the contradiction between the specificity of the transaction object cost maintenance and the total transaction cost that the transaction subject strives to be low. To sum up, the economic value of patents is very high today when scientific and technological innovation is advocated. Patent trading has also become a common activity in the patent application market. At present, contract transaction is the main way to buy and sell patents. In addition, bidding, auction and electronic bidding are all modes of patent trading. The subject and object of patent transaction have certain particularity.
