A prima facie obviousness rejection combining multiple disclosures requires a reason to modify or combine the prior art to achieve the claimed invention with a reasonable expectation of success.  In Ex parte Liu (Appeal No. 2018-001645), the Patent Trial and Appeal Board (“Board”) reversed the Examiner’s obviousness rejections because the Board found teachings in the prior art references to be inconsistent such that there would not have been a reason to modify or combine the prior art in the manner as set forth in Appellant’s claims.
