Appeal 2006-2690
Application 10/101,242
According to Appellants, the invention is directed to a glass article
comprising a first surface having a light scattering surface portion formed of
particles arranged in a pattern, and a second surface spaced from the first
surface, where the particles are deposited onto a float glass ribbon in a float
chamber to incorporate at least a portion of the particles into the ribbon to
form the light scattering surface (Br. 2). Independent claim 34 is illustrative
of the invention and is reproduced below:
