why these two references are adequate to show that the art
regularly
increased the radiation intensity in the latter stages of
polymerization. Regardless, the examiner must provide
evidence which shows that it would have been prima facie
obvious to one of ordinary skill in the art, when carrying out
the Martens process, to increase the radiation intensity in
the manner recited in appellants’ claim 1. As discussed
above, the Yada and Bartissol process differ from the Martens
process in that they are aqueous systems, polymerize different
monomer mixtures than those used by Martens, and make
different products than the pressure sensitive adhesive made
by Martens. The examiner has not explained why, regardless of
these differences, the use of more intense light in a latter
stage of the Yada and Bartissol processes would have fairly
suggested, to one of ordinary skill in the art, use in the
Martens process of a second irradiation stage wherein the
light intensity is greater than 20 mW/cm2. Moreover, the
