              Appeal No. 2006-0180                                                                 Παγε 3                                       
              Application No. 10/369,343                                                                                                        


                                                       OPINION                                                                                  
                     In reaching our decision in this appeal, we have given careful consideration to                                            
              the appellant's specification and claims, to the applied prior art references, and to the                                         
              respective positions articulated by the appellant and the examiner.  As a consequence                                             
              of our review, we make the determinations which follow.                                                                           
                                                  Claim Interpretation                                                                          
                     A central issue in dispute in this appeal is whether the operating room having an                                          
              operating table is positively recited in independent claims 1 and 2.  The preamble of                                             
              each of these claims recites apparatus "for use in an operating room with a structural                                            
              ceiling and having an operating table located therein" (emphasis added).  If we stopped                                           
              reading the claim at this point, we might infer that the operating room is not positively                                         
              recited as part of the invention but, rather, is the intended environment of use for the                                          
              claimed apparatus.  Claims 1 and 2 go on, however, to recite "a set of primary rails                                              
              connected to the operating room [or to the ceiling of the operating room]."                                                       
                     The preamble of a claim does not limit the scope of the claim when it merely                                               
              states a purpose or intended use of the invention; however, terms appearing in a                                                  
              preamble may be deemed limitations of a claim when they give meaning to the claim                                                 
              and properly define the invention.  See In re Paulsen, 30 F.3d 1475, 1479, 31 USPQ2d                                              
              1671, 1673 (Fed. Cir. 1994).  Although no litmus test exists as to what effect should be                                          
              accorded to words contained in a preamble, review of a patent application in its entirety
