Appeal No. 2000-0380
Application No. 08/816,648
uncoded binary data on a magnetic recording medium to enhance timing recovery.
Independent claim 25 is reproduced as follows:
25. A method for storing input groups of uncoded binary data on a
magnetic recording medium to enhance timing recovery, each said group
comprising a sequence of uncoded binary data, wherein the method
comprises the steps of:
encoding each input group using an m/n rate block coded sequence and
impressing a predetermined bit pattern thereon to provide corresponding
output groups of encoded binary data; and
storing the output groups on the magnetic recording medium.
The sole reference relied on by the Examiner is as follows:
Knudson 5,521,945 May 28, 1996
Claims 25 through 28 and 44 through 47 stand rejected under 35 U.S.C. § 102 as
being anticipated by Knudson.
Rather than repeat the arguments of Appellants and the Examiner, we make
1
reference to the briefs and the answer for the details thereof.
OPINION
After a careful review of the evidence before us, we do not agree with the Examiner
that claims 25 through 28 and 44 through 47 are anticipated by Knudson.
It is axiomatic that anticipation of a claim under §102 can be found only if the prior
1Appellants filed an appeal brief on May 3, 1999. Appellants filed a reply brief on July 7, 1999.
The Examiner mailed an office communication on July 22, 1999 stating that the reply brief had been entered
and considered.
