My Guide to Downloading PDF Patents has been updated with the following information:
IV. Patent Searching Resources.
a. Patent Search Software. Via Indian patent firm Parker & Parker. Stand alone program. Free. Allows you to search patents from the USPTO Issued and Published Patents, and EUROPEAN Patents Database…by entering one word in any of the field of software you can search in all three places. Pretty nice program.
b. ClassClarify. A software tool designed to aid researchers in using the USPTO’s Manual of Classification, the tool examiners use to categorize patents. ClassClarify graphically represents the manual and the relationships amongst the classes, it’s like a road map through the vast landscape of prior art. Use it to understand how examiners and industry analysts research prior art, and to perfect your searching skills.
