achieved that goal. More importantly, though, appellants
discuss Mathews in the specification and at least imply that
Mathews' arc lamp is operated in a vertical orientation. (See
specification, page 2, lines 17-25, and page 6, lines 15-30.)
Therefore, we find that Mathews is directed to a vertically
aligned arc lamp.
Appellants further argue that de Vrijer discloses a
horizontally aligned lamp tube which is elongated to improve
the headlight beam when light is reflected from a conventional
reflector, whereas Mathews is for use with an optical fiber
and
therefore does not have the same problems associated with the
reflector. Thus, appellants assert that there is no reason to
apply the shape of de Vrijer's arc lamp with Mathews' lamp.
We agree with appellants that de Vrijer does not suggest
a reason to use an elongated arc tube in the vertically
aligned lamp of Mathews, as the problems solved by de Vrijer
