THE REJECTION
Claims 1 and 3 stand rejected under 35 U.S.C. § 103 as being
unpatentable over Verschueren in view of Thornton.
OPINION
We reverse the aforementioned rejection. We need to address
the sole independent claim, i.e., claim 1.
Verschueren discloses a high-pressure discharge lamp
(col. 1, line 6) comprising a discharge vessel (3) which is

strong green and yellow emissions, strong violet emission, and
short and long wavelength ultraviolet emissions (col. 1,
