In one embodiment, the patent classification code data item in the second search criterion instruction is used to retrieve, from the plurality of first patent document data item, the patent document data items containing the patent classification code data item (that is, the patent document data items that contain the same patent classification code data item as in the second search criterion instruction). It should be understood that the patent classification code data item contains codes or numbers of certain patent classification system, which may be the International Patent Classification (IPC) system, Cooperative Patent Classification (CPC) system or United States Patent Classification (UPC) system, but is not limited thereto. Preferably, the patent classification code data item is a data item that has a hierarchical structure (that is, the patent classification system shown in this data item adopts a hierarchical structure to classify patent documents). Preferably, a patent document data item may include a plurality of patent classification code data items; for example, a patent document data item may include one or more main patent classification code data items and one or more secondary patent classification code data items. In different embodiments, a patent classification code data item may at least include a first-level patent classification code data item, a second-level patent classification code data item, a third-level patent classification code data item, and a fourth-level patent classification code data item. In different embodiments, a patent classification code data item may at least include a first-level patent classification code data item, a second-level patent classification code data item, a third-level patent classification code data item, a fourth-level patent classification code data item, and a fifth-level patent classification code data item.

In one embodiment, first, the server sequentially sums up the percentages corresponding to the respective patent classification code data items in the classification ranking data item 720 until the total percentage of the top N patent classification code data items is greater than the predetermined percentage data item 730. Next, the server retrieves the plurality of second patent document data items from the plurality of first patent document data items based on the first search criterion instruction and the top N patent classification code data items, wherein the plurality of second patent document data items 740 all meet the first search criterion, and each of the plurality of second patent document data items 740 contains one of the top N patent classification code data items. Moreover, the plurality of fourth patent document data items 710 include the plurality of second patent document data items 740. It should be understood that, since a patent document data item containing one of the top N patent classification code data items is more likely to be a patent that the user needs, the search system according to this invention can provide the user with a plurality of second patent document data items that will better meet the user's needs for the user to select therefrom. In this way, the patent document data items that the user needs can be retrieved more efficiently. In one embodiment, the plurality of second patent document data items 740 include a plurality of fifth patent document data items, a plurality of sixth patent document data items, and a plurality of seventh patent document data items. Also, each of the plurality of fifth patent document data items contains (or is associated with) a fifth patent classification code data item 722; each of the plurality of sixth patent document data items contains (or is associated with) a sixth patent classification code data item 724; and each of the plurality of seventh patent document data items contains (or is associated with) a seventh patent classification code data item 726. Specifically, the fifth patent classification code data item 722 ranks first in the classification ranking data item 720; the sixth patent classification code data item 724 ranks second in the classification ranking data item 720; and the seventh patent classification code data item 726 ranks third in the classification ranking data item 720. In addition, at least one of the plurality of second patent document data items 740 contains the fifth patent classification code data item 722; at least one of the plurality of second patent document data items 740 contains the sixth patent classification code data item 724; and at least one of the plurality of second patent document data items 740 contains the seventh patent classification code data item 726.
It should be understood that the patent search system according to this invention can assist the user to gradually narrow down the number of patents in a target patent group through one or more rounds of search during the search process. For example, the user can make selections for the search results of the first round, so that the server can generate the search criterion instruction of the next round (second search criterion instruction) and the corresponding search results (second search results) based on the one or more selection instructions and the corresponding one or more selected patent document data items. Thereafter, for the second search results, the user can repeat the foregoing process to obtain third search results, and repeat the foregoing process for the third search results to obtain fourth search results, and so on, until the user believes that the total number of target patent document data items has satisfied the user's needs.
In one embodiment, after the server of the patent search system according to this invention retrieves a plurality of third patent document data items from the plurality of first patent document data items based on the second search criterion instruction, the server can receive a third selection instruction provided by the user. The third selection instruction is associated with a third selected patent document data item in the plurality of third patent document data items, and is also associated with a third related-tag data item. Next, the server can obtain an eighth patent classification code data item from the third selected patent document data item based on the third selection instruction. And the server can generate a third search criterion instruction based on at least the first search criterion instruction provided by the user and the eighth patent classification code data item, wherein the third search criterion instruction includes the eighth patent classification code data item. Specifically, the first patent classification code data item indicates a first patent classification code, and the eighth patent classification code data item indicates an eighth patent classification code, which belongs to a further detailed classification under the first patent classification code in a hierarchy (for example, if the first patent classification code is a third-level patent classification code, then the eighth patent classification code can be a fourth-level patent classification code or a fifth-level patent classification code related to the first patent classification code.)
Then, the server can retrieve a plurality of eighth patent document data items from the plurality of first patent document data items in the database based on the third search criterion instruction, wherein at least one of the plurality of eighth patent document data items contains the eighth patent classification code data item. Preferably, the third search criterion instruction indicates a third search criterion, and the server retrieves the plurality of eighth patent document data items from the plurality of first patent document data items based on the condition that the plurality of eighth patent document data items all meet the third search criterion. It should be understood that by using the hierarchical characteristics of patent classification codes to gradually retrieve patents under a more detailed classification, the patent search system of the invention can effectively assist users in narrowing down the number of retrieved patents and/or obtaining more precise search results.
