Patent retrieval method and system

Abstract

The patent retrieval method comprises the following steps: receiving a patent application number input by a user; Searching whether a patent database has a patent or a patent application matched withthe patent application number input by the user or not; If the search result is that no patent or patent application matched with the patent application number input by the user exists in the patent database, searching whether a patent application number exists in the patent database or not and only one patent or patent application with different numbers exists in the patent application number input by the user; and outputting matched patents or patent applications if the search result is that there are only one patent or patent applications with different numbers in the patent application number and the patent application number input by the user in the patent database. Therefore, under the condition that the patent application number input by the user is wrong, a certain space still exists for further screening patents or patent applications required by the user, and the operability is high. The invention further provides a patent retrieval system.

Description

technical field [0001] The invention relates to the field of retrieval, in particular to a patent retrieval method and system. Background technique [0002] With the improvement of the intellectual property legal system and the strengthening of law enforcement, enterprises' awareness of intellectual property protection has also been continuously improved. The investigation of patent distribution and the retrieval of patent-related information have become an important task in the development process of enterprises; and many enterprises have established or are establishing internal patent databases to guide product development and production. [0003] Currently there is a patent retrieval method that manually enters the patent application number on the retrieval interface of the patent retrieval system for query. However, once the user enters the wrong patent application number, the patent search system will not provide any search information, and the operability is relativel...
