Appeal No. 1996-3324
Application No. 08/132,969
as part of dependent claim 4, which relates the output
voltages of each of the claimed converters to the value of D .
1
In our opinion, this equation on its face supports the
implication that the inputs of the claimed second and third
D/A converters are dependent in some fashion on the value of
D . For all of the above reasons, the Examiner’s 35 U.S.C. §
1
112, first paragraph rejection of independent claim 1 and
claims 2-7 dependent thereon
is sustained.
The rejection of claims 1-4 as anticipated
by the Data Converter Reference Manual.
We note that anticipation is established only when a
single prior art reference discloses, expressly or under the
principles of inherency, each and every element of a claimed
invention as well as disclosing structure which is capable of
performing the recited functional limitations. RCA Corp. v.
