beneficial properties (Brief, pages 2-3). A copy of
illustrative claim 15 is reproduced below:
15. The method of modifying elastic properties of
extruded net containing elastomeric strands, comprising:
providing extruded net having extruded strands, at least
some of which are elastomeric strands;
selecting end use performance criteria for desired final
elastic properties for the elastomeric material making up the
elastomeric strands in the net;
determining, based on hysteresis performance data, the
stretch conditions necessary to achieve the desired final
properties, and
stretching the elastomeric stands under the determined
conditions to achieve the desired final properties in the
elastomeric strands.
The examiner has relied upon Himelreich, Jr.
(Himelreich),
U.S. Patent No. 4,469,738, issued on Sep. 4, 1984, as evidence
of obviousness. Accordingly, the claims on appeal stand
rejected under 35 U.S.C. § 103 as unpatentable over Himelreich
