Appeal No. 2001-2351
Application No. 08/772,443
as a buffer, and at page 2, line 27 to page 3, line 7, appellants
disclose that their invention relates to non-cached disk read
operations and apparatus. The written description can provide
guidance as to the intended meaning of the claims, thereby
dictating the manner in which the claims are to be construed,
even if the guidance is not provided in explicit definitional
format. SciMed Life Systems v. Advanced Cardiovascular Systems,
242 F.3d 1337, 1344, 58 USPQ2d 1059, 1065 (Fed. Cir. 2001).
Accordingly, appellants’ claimed buffer is not met by Parks’
cache memory, and the buffer of the claims is not broad enough to
encompass a cache memory.
Although we will not sustain the rejection of claims 1, 4,
9, 20 and 31, we agree with the examiner that transfer of data
from the bus to the host without requiring transfer of the data
using the data buffer is taught by Parks. Assuming for purposes
of argument only that local memory 324 of Parks is a buffer,
Parks transfers data from bus 326 to the host 303 without
requiring transfer of the data using data buffer 324 because on
readout, the data from SCSI devices 306 proceeds through
processors 328 or 330, bus 326, snooping bus bridge 320, and bus
306 without using buffer 324.
