Referring to fig. 1, a system architecture diagram of an embodiment of a patent retrieval system according to the present invention is illustrated. In the embodiment shown in FIG. 1, the patent search system 100 comprises a database 110 and a server 120, wherein the server 120 accesses (or is communicatively coupled to) the database 110, and wherein the server 120 is communicatively coupled to one or more user devices 900. The user device 900 may be, for example, a computer, a tablet computer, a mobile device, etc., but is not limited thereto, and the user device 900 may have a display portion (for example, a display screen). Thus, the server 120 can display various data or instructions to the user for viewing through the display portion of the user device 900. In one embodiment, server 120 is communicatively coupled to user device 900 via a network (e.g., a wired network or a wireless network, etc.). In one 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 hardware and software co-operation. In one embodiment, the user device 900 may include one or more processors and the user device 900 may operate in conjunction with hardware and software to transmit, receive, and process various data or instructions.

In one embodiment, the server 120 may include an internal processing device 122 and a communication device 124, the internal processing device 122 is communicatively connected to the communication device 124 and the database 110, the database 110 is communicatively connected to the communication device 124, and the server 120 may be communicatively connected to the user device 900 through the communication device 124. Wherein the server 120 receives various data or instructions from the user device 900 via the communication device 124, and the server 120 transmits various data or instructions to the user device 900 via the communication device 124. In addition, the server 120 processes various data or instructions via 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 hardware and software co-operation.

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, but is not limited thereto. The server 120 may receive a first search condition instruction provided by a user, and may further search (retrieve) a plurality of second patent document data (may be referred to as a second patent document data group) from the plurality of first patent document data according to the first search condition instruction. The first search condition instruction indicates a first search condition, and the server 120 searches the plurality of second patent document data from the plurality of first patent document data based on the plurality of second patent document data satisfying the first search condition. Then, the server 120 may transmit the search result (i.e., the plurality of second patent document data) to the user device 900, and the display portion of the user device 900 may display the search result for the user to view. The user can read one or more patent document data (which may be referred to as one or more selected patent document data) in the plurality of second patent document data, and respectively give the one or more selected patent document data corresponding selection instructions. The selection instructions respectively indicate that the corresponding selected patent document data is related patent (i.e. patent required by the user) or non-related patent (i.e. patent not required by the user). In one embodiment, the selection instruction associated with selecting patent document data may be associated with related tag data or non-related tag data. Wherein, the related label data indicates that the patent document data is selected as the patent required by the user or the patent deemed to be related by the user, and the non-related label data indicates that the patent document data is selected as the patent not required by the user or the patent deemed to be irrelevant by the user.

The server 120 may obtain keyword data from the one or more selected patent document data according to the one or more selected patent document data and the corresponding selection instruction. And the server 120 may generate a second search conditional instruction based at least on the first search conditional instruction and the obtained keyword data. Wherein the second search conditional instruction includes the obtained keyword data. Then, the server 120 may retrieve a plurality of third patent document data (may be referred to as a third patent document data group) from the plurality of first patent document data according to the second retrieval condition instruction. Preferably, the second search condition instruction indicates a second search condition, and the server 120 searches the plurality of third patent document data from the plurality of first patent document data based on the plurality of third patent document data satisfying the second search condition. Preferably, the second search condition includes the first search condition. In one embodiment, the keyword data in the second search conditional instruction is used to search a plurality of patent document data having the keyword data from a plurality of first patent document data (herein, the patent document data having the keyword data refers to the same word as the keyword is described in the patent document). In one embodiment, the key data in the second fetch conditional instruction is used to retrieve a plurality of patent document data from the plurality of first patent document data that does not have the key data.

In one embodiment, the first search conditional instruction includes initial keyword data provided by a user, and the server 120 searches a plurality of second patent document data from a plurality of first patent document data according to the first search conditional instruction. Wherein, the plurality of second patent document data all have initial key word data. In one embodiment, the first search conditional instruction includes initial keyword data provided by a user, and the server 120 searches a plurality of second patent document data and a plurality of fourth patent document data (which may be referred to as a fourth patent document data group) from a plurality of first patent document data according to the first search conditional instruction. Wherein each of the plurality of second patent document data includes title (title) data, abstract (abstract) data, description (description) data, and claim (claim) data, and one of the title data, the abstract data, and the claim data corresponding to each of the plurality of second patent document data has the initial keyword data. The plurality of fourth patent document data all have the initial keyword data. That is, if one of the invention name data, abstract data, and claim data of the patent document data has the initial keyword data, the server 120 lists it as the second patent document data. If the patent document data has the initial keyword data, but the patent document data does not have the initial keyword data, the invention name data, the abstract data, and the claim data, the server 120 classifies the patent document data as the fourth patent document data. It should be appreciated that, since the probability that each second patent document data is a related patent (i.e. a patent required by the user) is high, when the search result of the first search condition instruction (i.e. the plurality of second patent document data and the plurality of fourth patent document data) is displayed for the user to watch, the server 120 may display the plurality of second patent document data in a more obvious place, for example, the plurality of second patent document data may be arranged in the front stage and the plurality of fourth patent document data may be arranged in the rear stage, but not limited to this display manner. Preferably, different search results can be provided for the user to watch and select according to different conditions. In one embodiment, when the user wants to check, the server can provide the plurality of second patent document data for the user to view and check according to the first search condition instruction. When the user wants to check the whole, the server can provide a plurality of second patent document data and a plurality of fourth patent document data for the user to watch and check according to the first search condition instruction.

In one embodiment, the server 120 receives a first selection command provided by a user, where the first selection command is associated with a first selected patent document data of the plurality of second patent document data.

Then, the server 120 may generate a second search conditional instruction according to at least the first search conditional instruction and the first keyword data, and the second search conditional instruction includes the first keyword data. The server 120 retrieves a plurality of third patent document data from the plurality of first patent document data according to the second retrieval condition instruction. In one embodiment, the first selection command is associated with the relevant tag data (e.g., the first selection command may have relevant tag data), and each of the plurality of third patent document data retrieved by the server 120 has first keyword data. In one embodiment, before the server 120 retrieves the plurality of third patent document data, the server 120 may provide the second search conditional instruction to the user for viewing and confirmation, and the user may determine whether to keep each keyword in the second search conditional instruction. Thus, when the server 120 obtains a plurality of keyword data according to the selected patent document and the corresponding selection instruction, the user can further confirm which keywords are suitable for being used as keywords in the search conditional instruction, and then search is performed in the next round. For example, the user may provide a deletion instruction to the server 120 before the server 120 retrieves the plurality of third patent document data, and the server 120 may delete the first keyword data from the second retrieval condition instruction according to the deletion instruction.

In one embodiment, the server 120 receives a first selection instruction provided by a user, the first selection instruction is associated with a first selected patent document data of the plurality of second patent document data, and the first selection instruction is associated with the relevant tag data.

In one embodiment, if all selected patent document data associated with the associated tag data has particular keyword data, the server 120 of the patent retrieval system 100 may list the particular keyword data as keyword data suggested for use in the scaling (i.e., combined with the logical operator "and"). If all the selected patent document data associated with the non-relevant tag data has the specific keyword data, and all the selected patent document data associated with the relevant tag data does not have the specific keyword data, the server 120 may list the specific keyword data as the keyword data suggested for exclusion (i.e. combined with the logical operator "not").

The aforementioned keywords may be keywords (key word) or keywords (key phrase). In addition, the first search conditional instruction may include a keyword and/or a patent country and/or a patent classification number, but is not limited thereto. It should be appreciated that the patent search system 100 of the present invention can gradually reduce the number of target patent groups through one or more rounds of search in assisting the user in searching. For example, the user may associate one or more selection instructions (each selection instruction may include related tag data or non-related tag data) with one or more selected patent document data in the search results, respectively, and generate, by the server, a search condition instruction (second search condition instruction) and a corresponding search result (second search result) of the next round according to the one or more selection instructions and the corresponding one or more selected patent document data. Then, the user may repeat the foregoing process for the second search result to obtain the third search result, and may repeat the foregoing process for the third search result to obtain the fourth search result, and so on. Until the user considers that the total number of the current target patent document data can meet the requirement of the user.
