             Application 08/202,536                                                                               

                          In many cases it is desirable to apply an                                               
                    electroless deposition solution to a surface which                                            
                    is not amenable to immersion in a plating bath, e.g.                                          
                    because the substrate is not stable in aqueous                                                
                    solutions, because the substrate is large or fixed                                            
                    in place in a way that prohibits immersion in a                                               
                    solution or because it is desirable to restrict the                                           
                    application of plating solution to the region of a                                            
                    catalytic image.  In such cases it would be useful                                            
                    to employ a highly viscous electroless plating                                                
                    solution that would be substantially immobilized                                              
                    when applied to a substrate, i.e. would not run from                                          
                    the localized area of application.  A common belief                                           
                    in the field of electroless plating solution is that                                          
                    plating baths must be well agitated to allow                                                  
                    sufficient mass transfer of metal to a catalytic                                              
                    surface and liberation of hydrogen from the plating                                           
                    surface.  For instance, if hydrogen, which is                                                 
                    liberated during the reduction of ionic metal to                                              
                    deposited metal, is not removed from the surface,                                             
                    the transfer of ionic species to the surface is                                               
                    impeded.  Such a belief has not doubt inhibited the                                           
                    development of highly viscous plating media.                                                  
                    One reading the majority's opinion "affirming" the                                            
             examiner's adverse decision rejecting claims 10-18 and 25-27                                         
             under 35 U.S.C. § 103 would reasonably expect to find a                                              
             discussion regarding this critical finding by the examiner.                                          
             However, the majority has chosen not to decide this issue.  I                                        
             believe this constitutes procedural error on the part of the                                         
             majority.                                                                                            
                    Appellants' have invested a significant amount of                                             
             resources, both financially and timewise, in order for this
