35 U.S.C. §103

35 U.S.C. § 103 sets forth the "obviousness" requirement as a condition for patentability, which states that an invention must be non-obvious. In practical terms, this generally means that if a patent examiner can find all elements of an invention described in two or more printed publications and these publications relate to the same field of endeavor, then a 103 rejection will be issued by the USPTO.
