Appeal No. 96-0044
Application 08/014,136
to allow release of the metal layer from the plastic film (1-85% by weight to dry weight of
coating composition). The additive as defined by appellants in their specification includes
so-called release resins composed of fluorine-containing and/or fluorine-modified
polymers, silicone resins, silicone oils, polysiloxane and also conventional release agents
and lubricants, such as, for example, fatty acids and their metal salts, alkylamines, fatty
acid esters, fatty acid amides and sulfonates.
Kampf describes a coating composition comprising 10-100% by weight of an
intrinsically electrically conductive polymer, 0-90% by weight of a binder, a solvent and an
lubricant additive. The secondary references, the Textbook of Polymer Science and
Polymer Processes, describe known lubricants useful in plastics. It is the examiner’s
position that it would have been obvious to employ the lubricants of the secondary
references as the lubricant in Kampf. The examiner alleges that Kampf clearly teaches
percentages of lubricant additives which overlap with the instantly claimed percentages
(Answer, page 7, lines 7-9). However, the examiner fails to point out, and we fail to find,
where in Kampf this teaching can be found. Accordingly, we find no basis in fact for the
examiner’s allegation.
