Locate Defensive Publications?

TOPIC: A defensive publication, or defensive disclosure, is an intellectual property strategy used to prevent another party from obtaining a patent on a product, apparatus or method. The strategy consists in disclosing an enabling description and/or drawing of the product, apparatus or method so that it enters the public domain and becomes prior art. Therefore, the defensive publication of, perhaps otherwise patentable information, may work to defeat the novelty of a subsequent patent application.

You can search for Defensive Publicaitons in the following databases: CLAIMS®/U.S. Patents (File 340, 341, 942), U.S. Patents Fulltext (File 652, 654, PATFULL), Derwent World Patents Index® (File 351, 352 in Japan) and INPADOC/Family and Legal Status (File 345).

Note: To find all defensive publications in a database:

• In CLAIMS and U.S. Patents Fulltext, search Document Type (DT=) followed by DEFENSIVE (e.g., S DT=DEFENSIVE).
• In Derwent databases search the Patent Country prefix (PC=), enter the U.S. country code, a space, then the kind code H (e.g., S PC=US H).
• In INPADOC search the Patent Country prefix (PC=), enter the U.S. country code, a space, then the kind code I4, (e.g. S PC=US I4).
