Appeal No. 2006-0547
Application No. 10/276,568
anticipates the subject of a claim when the reference discloses every feature of the
claimed invention, either explicitly or inherently (see Hazani v. Int'l Trade Comm'n,
126 F.3d 1473, 1477, 44 USPQ2d 1358, 1361 (Fed. Cir. 1997) and RCA Corp. v.
Applied Digital Data Systems, Inc., 730 F.2d 1440, 1444, 221 USPQ 385, 388 (Fed.
Cir. 1984)); however, the law of anticipation does not require that the reference teach
what the appellants are claiming, but only that the claims on appeal "read on"
something disclosed in the reference (see Kalman v. Kimberly-Clark Corp., 713 F.2d
at 772, 218 USPQ at 789).
We must point out, however, that anticipation under 35 U.S.C. § 102 is
established only when a single prior art reference discloses, either expressly or under
the principles of inherency, each and every element of a claimed invention. See RCA
Corp. v. Applied Digital Data Systems, Inc., 730 F.2d 1440, 1444, 221 USPQ 385,
388 (Fed. Cir.); cert. dismissed, 468 U.S. 1228 (1984).
Appellant argues that in accordance with the invention, the polysilicon resistor
has a linear voltage drop along its length and is formed so as to provide signal
transmission between the high pressure side and the low pressure side. (Brief at page
5.) Appellant argues that the reference belongs to the same art and teaches some
features which are similar to the features of the present invention, but that Robb does
not disclose a power component in which, through a polysilicon resistor, a signal is
transmitted from the high pressure side to the low pressure side. (Brief at page 6.)
