                   Appeal 2006-2045                                                                                                
                   Application 10/284,357                                                                                          

                   “reasonable to presume” that these limitations would be met by the fabric                                       
                   disclosed by Taylor since Taylor uses similar materials as claimed with                                         
                   similar production steps (Answer 4).                                                                            
                          With regard to the rejection of claims 29 and 35-38, the Examiner                                        
                   recognizes that Taylor fails to teach using fire resistant materials in the                                     
                   woven fabric (Answer 5).3  Accordingly, the Examiner applies Goad for the                                       
                   teaching that medical fabrics, such as those disclosed by Taylor, must meet                                     
                   or exceed current fire standards, and this objective may be achieved by                                         
                   treating the fabrics with flame retardants to impart flame resistance (id.).                                    
                   From these findings, the Examiner concludes that it would have been                                             
                   obvious to one of ordinary skill in this art to apply a flame retardant, as                                     
                   taught by Goad, to the reusable medical fabric disclosed by Taylor (id.).                                       
                          Appellants argue that only the Examiner, not Taylor, identifies a so-                                    
                   called dpf (denier per filament) ratio from Example 1 of Taylor (Br. 10).                                       
                   Appellants argue that there is no basis provided by the Examiner or Taylor                                      
                   that such ratio is universally applicable to other deniers (Br. 11).  Appellants                                
                   refer to the Adams Declaration which concludes that the number of                                               
                   filaments of warp and weft yarns within respective denier ranges of 50-150                                      
                   and 100-300 in Taylor cannot be determined (Br. 10).  Appellants argue that                                     
                   Taylor does not give any indication as to which parameters are critical and                                     
                   thus no direction is given as to which of many choices is likely to be                                          
                   successful (Br. 13).  Appellants assert that the Examiner has only established                                  
                   an “obvious to try” standard (Br. 12-13).                                                                       

                                                                                                                                  
                   3 We note that Taylor does teach that the preferred fabric has a burn rate retardant finish                     
                   applied thereto to provide a required property (col. 7, ll. 15-22).                                             
                                                                4
