Appeal No. 2004-1099
Application No. 09/868,911
‘811, with regard to both Lenander and JP ‘118, is that all of the
references teach ultrasonic processing of polymeric materials. We
disagree for the following reasons.
JP ‘118 is directed to the ultrasonic sealing of two
superposed polymeric films (¶ [0010] and [0011]; see also Figure
1). This reference teaches that the connection part of the
sealed film is rapidly cooled by blowing compressed air either
simultaneously with or immediately after the connection of the film
by the ultrasonic waves (page 1, claims 1 and 2). JP ‘118 teaches
that the natural cooling and solidification of the connection part
causes the connection part to become fragile and easily ruptured
(¶ [0002] and [0003]). The inventor of JP ‘118 has found that
if the film part which is melted by ultrasonic energy is rapidly
cooled, it becomes amorphous and there is no deterioration of
mechanical strength (¶ [0006]). Because the ultrasonic welding
part of the film is rapidly cooled, “fragility is not generated,
and remarkably good welding strength can be obtained.”
¶ [0016][sic]. The result of the teaching of JP ‘118 is that
“where repeated bending stress is present, the connection part
does not rupture.” Id.
Therefore we determine that the teachings of JP ‘118 are
directly contrary to the expressed desires of JP ‘881 and Lenander,
