            Appeal No. 2000-0354                                                                       
            Application No. 08/682,471                                                                 


            at the references cited, in particular Kikinis (US# 5502838)                               
            which shows using temperature as a condition for reducing power.”                          
            Since the examiner has never cited this reference in the answer                            
            and has made no formal statement of rejection regarding it, we                             
            will not consider its teachings and suggestions.  “Where a                                 
            reference is relied on to support a rejection, whether or not in                           
            a minor capacity, that reference should be positively included in                          
            the statement of the rejection.”  Manual of Patenting Examining                            
            Procedure (MPEP) § 706.02(j).  This portion relies upon In re                              
            Hoch, 428 F.2d 1341, 1342 n.3, 166 USPQ 406, 407 n.3 (CCPA 1970).                          
                  We are constrained to reverse the outstanding rejection of                           
            claims 2-20 because there is no evidence before us of the feature                          
            of exceeding a threshold among the references relied upon by the                           
            examiner in formulating the rejection.  Essentially, we conclude                           
            the examiner has not set forth a prima facie case of obviousness                           
            as to these claims.  We reach this conclusion buttressed by the                            
            reasoning provided by recent cases from our reviewing court.                               
            “[T]he Board cannot simply reach  conclusions based on its own                             
            understanding or experience - or on its assessment of what would                           
            be basic knowledge or common sense.  Rather, the Board must point                          
            to some concrete evidence in the record in support of these                                
            findings.”  In re Zurko, 258 F.3d 1379, 1386, 59 USPQ2d 1693,                              

                                                  7
