System and method for searching patents using DNA fragment number

A system for searching patent documents using a DNA fragment number, comprising:

• a DNA fragment sequence database which stores information about DNA fragment sequences;
• a patent sequence database which stores information about patent DNA fragment sequences included in patent documents;
• a patent database which stores information about the patent documents;
• an interface which receives a DNA fragment number from at least one client as a first search term;
• a sequence extracting unit which extracts a DNA fragment sequence corresponding to the DNA fragment number from the DNA fragment sequence database in response to the DNA fragment number;
• a matching sequence search unit which searches for patent DNA fragment sequences having at least a portion matching the extracted DNA fragment sequence in the patent sequence database;
• a patent number extracting unit which searches for patent numbers of patent documents including the found patent DNA fragment sequences from the patent sequence database;
• and
• a patent search unit which searches for patent documents from the patent database in response to the extracted patent numbers.
