as recited in independent claims 1, 2, and 6. The motivation for
the combination is found in the nature of the fit problem to be
solved in the APA and the teaching of a solution to the problem
in Arai. The motivation to recess the gate landing and the gate
flash protrusion is also found in Arai's general teaching of this
feature and the teaching that the techniques can be used with any
injection molded product, include CRT products. An express
suggestion is not required to support an obviousness conclusion.

person of ordinary skill in the art's knowledge that it would
have been desirable to incorporate a recessed gate landing as
taught in Arai to eliminate the need for grinding in the APA;
this is the only motivation that relies on a finding of level of
skill in the art outside of what is shown in the references.
As to dependent claim 3, both the APA and Arai discuss

incorporation of a recessed gate flash protrusion as taught by
Arai into the APA would be oriented toward the CRT as in the APA,
