Teleflex Inc. These guidelines are intended to be used by Office personnel in conjunction with the guidance in the Manual of Patent Examining Procedure when applying the law of obviousness under 35 U.S.C. 103. Members of the public are invited to provide comments on the 2010 KSR Guidelines Update. The Office is especially interested in receiving suggestions of recent decisional law in the field of obviousness that would have particular value as teaching tools.
