Appeal No. 1998-2297
Application 08/353,622
Thomas discloses “an acidic microemulsion that can be
sprayed onto the surface to be cleaned, and wiped off without
usual rinsing, and still will leave the cleaned surface bright
and shiny” (col. 1, lines 11-14).
The appellant’s claim 1 recites that a pad having thereon
an abrasive, acidic composition is affixed to a portable,
power tool which is rotated at high speed until the glass
surface is clean. During patent prosecution, claims are to be
given their broadest reasonable interpretation consistent with
the specification, as the claim language would have been read
by one of ordinary skill in the art in view of the
specification and prior art. See In re Zletz, 893 F.2d 319,
321, 13 USPQ2d 1320, 1322 (Fed. Cir. 1989); In re Sneed, 710
F.2d 1544, 1548, 218 USPQ 385, 388 (Fed. Cir. 1983); In re
Herz, 537 F.2d 549, 551, 190 USPQ 461, 463 (CCPA 1976); In re
Okuzawa, 537 F.2d 545, 548, 190 USPQ 464, 466 (CCPA 1976); In
re Kroekel, 504 F.2d 1143, 1146, 183 USPQ 610, 612 (CCPA
1974); In re Moore, 439 F.2d 1232, 1235, 169 USPQ 236, 238-39
