The Ocean Tomo PatentRatings¨ System uses a patented (USP 6,556,992 and other US and foreign patents pending) method to calculate the relative quality of all patents issued by the USPTO since 1976 on the basis of more than 50 independent and objective factors. The IPQ® score represents a numerical measure of patent quality and value with a median score of 100 for US issued patents. The PatentRatings® System recalculates IPQ¨ scores on a monthly basis.
