Appeal 2007-0916
Application 10/051,486
fifth colored granules having a different coloration or shade than the second
colored granules."25
Claim 26: "the first colored granules form a shadow line adjacent the
leading edge of the tab across substantially the entire width of the tab."26
Claim 27: "the first colored granules comprise darker granules than
the second colored granules."27
Claim 33: "fifth colored granules adhere to the outer surface of each
of the tabs separated from the first and sixth colored granules by the second
colored granules, the fifth colored granules hav[ing] a different coloration or
shade than the second colored granules and form[ing] a fourth shadow line
adjacent the headlap section."28
Claim 43: "granules of the first color or shade are applied to portions
of the base material corresponding to the tab and spaced from the leading
edge of the tab and separated from the granules applied to the leading edge
of the tab by the granules of the second color."29
For the purposes of this decision, we may accept the differences
Owens Corning urges as differences from the prior art with a few caveats.
Owens Corning does not contend that its inventors invented overlays, tabs,
headlaps, the use of more than one color of granules, or the method of laying
down more than one color of granule. Instead, each stated difference
appears to relate to the positioning of a shadow line or colored granules.
