problem of short compressor life, but have failed to do so;
(5) Texas Instruments attempted to improve compressor life by
utilizing multiple individual springs with carefully
controlled angular orientation, but these showed no
substantial improvement; and
(6) Hughes Aircraft Company (the real party in interest in
this application) in the two years following the use of the4
double helix spring in their coolers has sold approximately
600 linear coolers compared to selling less than 50 linear
coolers in the two years prior to the use of the double helix
spring in their coolers. In addition, Pruitt states that the
improvement shown by his invention when compared to the prior
art "is a dramatic and completely unexpected magnitude of
improvement" and that the improvement in wear and life of the
linear compressor is "significant and startling."
