Abstract: A method for classifying patent documents may include the steps of identifying original patent documents in a patent pool identified according to a search and/or selection input of a user, determining the first patent documents classified in the classification generated by the user, among the original patent documents in the patent pool; outputting an indication for accuracy related to the automatic classification; and performing the automatic classification for second patent document which are not yet classified, among the patent documents in the patent pool.

Abstract: A method for classifying patent documents may include the steps of learning patent documents stored in a patent database by machine learning technology, establishing a first classification standard based on similarity between the patent documents, and generating a basic classification model of classifying the patent documents based on the first classification standard; generating a patent pool including a plurality of patent documents based on a search and/or selection input of the user; receiving the classification input of the user and classifying the plurality of patent documents included in the patent pool according to the classification input; predicting a second classification standard classifying the plurality of patent documents by the user based on the similarity between the classified patent documents; and classifying remaining patent documents which are not yet classified in the patent pool based on the basic classification model and the second classification standard.

Abstract: A method for outputting a drawing reference number description regarding a patent drawing reference number according to an embodiment of the present disclosure may include recognizing a size of a patent drawing and a position of a drawing reference number included in the patent drawing and acquiring a relative position coordinate of the drawing reference number in the patent drawing; setting a relative position coordinate of the drawing reference number description corresponding to the drawing reference number based on the acquired relative position coordinate; and outputting the drawing reference number description on the set relative position coordinate, thereby outputting such that the drawing reference number description corresponds to the drawing reference number.

Abstract: Provided is a method for automatically creating a user-customized document, and the method includes: receiving an automatic document creation target from a user, wherein the automatic document creation object comprises a plurality of data items and a plurality of tags matching the plurality of data items is defined; receiving, from the user, a template file in which a format of the user-customized document is set, wherein the template file comprises at least one tag; and generating the user-customized document by replacing each tag in the template file with a data item matching a corresponding tag in the automatic document creation target.
