operations implies that the polythiophene with conjugated
polymer backbone has to withstand temperatures up to 200EC
during heat setting and stretching without prohibitive
coloration and without losing its conductivity” (page 3 of
principal brief, second paragraph).
Appealed claims 1-12 stand rejected under 35 U.S.C. 103
as being unpatentable over Tanabe in view of Jonas.
Upon careful consideration of the opposing arguments
