`Motion to Amend
`
`Microsoft does not contest that Substitute Claims 35-
`41 are patentable over Perlman, the Combination of
`Perlman and Yohe, Santos, and the Combination of DRP
`and Mattis.
`
`Only 2 Grounds of Review are at issue for the Motion to
`Amend
`– Anticipation by Yohe of Claims 1, 3, 6, 7, 10, 22-23
`– Anticipation by DRP of Claims 6, 7, 9, 11, 12, 14

`Motion to Amend
`
`Microsoft is improperly attempting to introduce
`New Grounds of Rejection.
`– Claims 1, 3, 10, and 22-23 are not subject to any
`Ground of Review involving DRP.
`– Microsoft has waived challenge to this subject matter
`in view of DRP.
`– Substitute Claims 35, 36, 38, and 40-41 are amended
`versions of Claims 1, 3, 10, and 22-23, respectively.
`
`DRP is irrelevant to Substitute Claims 35, 36, 38, and 40-41

`inherently includes at least one comparison of the
`particular digest to one of multiple digests in the

`additional Digital Digests, until a match is found.

`With regard to Yohe:
`– In the READ operation, the remote client 12 does
`not send a request, but instead sends the
`identifier.
`– In the DIRECTORY operation, the remote client
`sends a request for a signature for the directory,
`not the directory itself.
`– Further, there is no searching for a directory
`signature in the remote client, because only one
`directory signature is present.

`
`• Claim 41 is merely amended to make it consistent with the
`Amendment to claim 40, from which it depends.
`– The claim is responsive and supported by the original
`specification
`– Further, in combination with claim 40, it is certainly more
`narrow than original claim 22. Thus, there has been no enlarged
`claim scope.
`– Claim 41 is patentable of Yohe for the reason explained above
`with reference to Claim 40
