In the embodiment shown in FIG. 1 , the patent retrieval system 100 includes a database 110 and a server 120 , the server 120 accesses (or communicates with) the database 110 , and the server 120 can communicate with one or more user devices 900 . Wherein, the user device 900 may be, for example, a computer, a tablet computer, a mobile device, etc., but not limited thereto, and the user device 900 may have a display portion (such as a display screen). In this way, the server 120 can display various data or instructions for the user to watch through the display part of the user device 900. In a specific embodiment, the server 120 communicates with the user device 900 through a network (such as a wired network or a wireless network, etc.). In a specific embodiment, the patent retrieval system 100 of the present invention includes one or more processors, and the patent retrieval system 100 implements the database 110 and/or the server 120 in a cooperative manner of hardware and software. In a specific embodiment, the user device 900 may include one or more processors, and the user device 900 transmits, receives, and processes various data or instructions in a cooperative manner of hardware and software.

In a specific embodiment, the server 120 may include an internal processing device 122 and a communication device 124, the internal processing device 122 is connected to the communication device 124 and the database 110, the database 110 is connected to the communication device 124, and the server 120 can communicate with the communication device 124 The user device 900 is connected by communication. Wherein, the server 120 receives various data or instructions from the user device 900 through the communication device 124, and the server 120 transmits various data or instructions to the user device 900 through the communication device 124. In addition, the server 120 processes various data or instructions through an internal processing device 122 . Preferably, the server 120 includes one or more processors, and the server 120 implements the internal processing device 122 and/or the communication device 124 in a cooperative manner of hardware and software.

In the embodiment shown in FIG. 1 , the database 110 stores a plurality of first patent document data (which may be referred to as a first patent document data group). Preferably, the plurality of first patent document data may include patent documents of different countries or different fields, and it is not limited thereto. The server 120 can receive the first retrieval condition instruction provided by the user, and can further retrieve a plurality of second patent document data from the plurality of first patent document data according to the first retrieval condition instruction ( may be referred to as the second patent document data group). Wherein, the first retrieval condition command indicates the first retrieval condition, and the server 120 retrieves the plurality of second patent document data from the plurality of first patent document data based on the first retrieval condition. A second patent file data. Then, the server 120 can transmit the search result (ie, the plurality of second patent document data) to the user device 900, and the search result can be displayed for the user to watch through the display part of the user device 900. The user can read one or more pieces of patent document data among the plurality of second patent document data (this may be referred to as one or more pieces of selected patent document data), and give selection instructions corresponding to the one or more pieces of selected patent document data. Wherein, the selection instructions respectively indicate that the corresponding selected patent document data are related patents (namely patents required by the user) or non-related patents (namely patents not required by the user). In one embodiment, selection instructions associated with selecting patent document data may be associated with relevant tag data or non-related tag data. Among them, the relevant tag data indicates that the selected patent document data is a patent that the user needs or that the user thinks is relevant, while the non-related tag data indicates that the selected patent document data is a patent that the user does not need or that the user thinks is irrelevant.

The server 120 can obtain keyword data from the one or more pieces of selected patent document data according to the one or more pieces of selected patent document data and their respective corresponding selection instructions. And the server 120 can at least generate the second retrieval condition instruction according to the first retrieval condition instruction and the obtained keyword data.
