Oriented to patent data fields, taking the characteristics of patent document and the requirement of patent analysis into account, this paper puts forward an improved method of patent data approximately duplicate attributes and records detecting based on RFMA algorithm and PCM algorithm, which is IRPU algorithm. Then IRPU algorithm is applied in patent data to detect inventor attribute and whole record. Experimental comparison with the previous work indicates that the proposed method is fit for patent data field and the identification accuracy is higher.
