Abstract: A method, system and program for facilitating consideration of clearance of a target sequence. The method comprises retrieving a predefined patent document library data structure having fields for claim identifiers, a matching criterion for a comparison, translated claim statements, matching procedures, sequence identifiers, logical relationships between claim statements and machine readable comparison instructions; retrieving a sequence database indexed by sequence identifier, comparing the target sequence with each of the claims in the retrieved patent document library data structure, using a corresponding machine readable comparison instructions and a sequence which is obtained from the retrieved sequence database corresponding to a sequence identified in the claim and determining whether each of claims in the retrieved patent document library data structure matches the target sequence based upon a result of the comparison.
