PatentHunter is a software program that helps patent attorneys, businesses and inventors search, download and manage United States and foreign patents. Unlike commercial providers who can charge $3 to $5 per patent, downloading patents with PatentHunter is FREE because PatentHunter searches patents and downloads complete patent images from the USPTO and EPO websites.
