Abstract: Provided is a patent transaction prediction method, comprising the following steps: obtaining to-be-predicted patent data(S1); constructing a prediction model, which is executed by a computer to predict a transaction probability of to-be-predicted patent data(S2); and displaying the transaction probability in a data attribute of the to-be-predicted patent data(S3). According to the method, the probability of patent transactions is displayed in the attribute of the patent data, improving the probability of patent transaction. Also provided are a patent transaction prediction system and a patent transaction platform, which also have the above-mentioned advantages.
