`
`DETAILED ACTION
`
`1.
`
`Claims 1-26 are presented for examination.
`
`Specification
`
`2.
`
`The abstract is objected to because it uses language which can be implied “A method
`
`i_s
`
`disclosed”.
`
`Claim Rejections - 35 USC § 103
`
`3.
`
`The following is a quotation of35 U.S.C. 103(a) which forms the basis for all obviousness
`
`rejections set forth in this Office action:
`
`(a) A patent may not be obtained though the invention is not identically disclosed or described as set forth in
`section 102 of this title, if the differences between the subject matter sought to be patented and the prior art are
`such that the subject matter as a whole would have been obvious at the time the invention was made to a person
`having ordinary skill in the art to which said subject matter pertains Patentability shall not be negativecl by the
`manner in which the invention was made
`
`This application currently names joint inventors.
`
`In considering patentability of the claims
`
`under 35 USC. 103(21), the examiner presumes that the subject matter of the various claims was
`
`commonly owned at the time any inventions covered therein were made absent any evidence to
`
`the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor
`
`and invention dates of each claim that was not commonly owned at the time a later invention was
`
`made in order for the examiner to consider the applicability of 35 USC. l03© and potential 35
`
`USC. 102(f) or (g) prior art under 35 USC. 103(a).

`
`Claims 1-7 are rejected under 35 U.S.C. 103(a) as being unpatentable over Rostoker et al.
`
`(5,708,659).
`
`As per claims 1-7, Rostoker et al. substantially disclose the claimed method. In particular,
`
`Rostoker et al. disclose a method for hashing in a packet network switching system, waerein a
`
`decoder parses a bistream, separating out the sync, header information, allocations, and scale
`
`factors, performs CRC check, and removes ancillary data (see column 35, lines 8-11, ). See also
`
`Pig’s 30, 46, and 47 for more details. It is noted that Rostoker et al. do not explicitly disclose to
`
`compare the CRC code to at least one entry within a cache and in the event of a match to further
`
`process as recited in lines 16—23 of claim 1. However, it would have been obvious to a person of
`
`ordinary skill in the art at the time the invention was made to implement the claimed invention by
`
`incorporating the above limitation in Rostoker et al.’s method because one of ordinary skill in the
`
`art is well aware of the many ways that the CRC check can be used, to provide better performance
`
`in network devices.
`
`Allowable Subject Matter ’
`
`5.
`
`Claims 8-26 are allowable over the prior art of record.
