Appeal No. 2003-0090 Page 2
Application No. 09/006,379
THE CLAIMED SUBJECT MATTER
As claims 21-25, 27-34, and 56 are grouped together (Brief at 5), we focus on the only
independent claim, claim 21. Claim 21 reads as follows:
21. An article in the form of a free-standing film comprising:
(a) a base comprising a polymer layer having a major surface; and
(b) an anti-reflective stack optically coupled to said major surface of said base
that reduces the reflectivity of said base at said major surface over a wavelength range of
interest,
said stack comprising alternating layers of (i) high index polymer; and (ii) low index
polymer.
THE EVIDENCE
As evidence of unpatentability, the Examiner relies upon the following prior art
reference:
Schrenk et al. (Schrenk) 5,103,337 Apr. 7, 1992
THE REJECTION
Claims 21-25, 27-34, and 56 stand rejected under 35 U.S.C. § 102(b) as anticipated by or,
in the alternative, under 35 U.S.C. § 103(a) as obvious over Schrenk. We affirm substantially for
the reasons given in the Answer. We add the following primarily for emphasis.
