`
`Compression such as Content Dependent Data Compression,” assigned to
`
`Realtime Data LLC and issued to James J. Fallon (January, 9, 2007). Claims
`
`1-5, 8, 9, 11, 17, 20-23, 27, 39, 43, 69-73, 79, 81, 82, 84-90, 96, and 98

`
`STATEMENT OF THE CASE
`
`The ‘506 patent describes “data compression and decompression
`
`using content independent and content dependent data compression and
`
`decompression”(col.6, Il. 21-23).
`
`Claim | on appealreads as follows:
`
`1. A method for compressing data, comprising thestepsof:
`analyzing a data block of an input data stream to identify one or more
`data types of the data block, the input data stream comprising a plurality of
`disparate data types;
`performing content dependent data compression;if a data type of the
`data block is identified;
`performing data compression with a single data compression encoder,
`if the data type of the data block is not identified.

`
`Claim 20 is rejected under 35 U.S.C. 103(a) as being unpatentable over Sebastian in
`
`view of Franazek or Reynar.
`
`This rejection is adopted essentially as proposed by 3PR in 3PR Request.
`
`Regarding claim 20, Sebastian discloses a method as discussed above with regard to
`
`claim 1 but does not specifically disclose counting the size of the data block.
`
`However, Franazek teaches a system thatis related to the one described by Sebastian,
`
`including data compression, and teaches counting the size of the data block (column 5,lines 19-
`
`38). Reynar also teaches a system that is related to the one described by Sebastian, including data
`
`compression, and teaches counting thesize of the data block(i.e., the length of the documentor
`
`documentportion; column 14, lines 66-67; column15, lines 1-13).
`
`Regarding claim 20, it would have been obviousto a person of ordinary skill in the art to
`
`countthe size of the data block as taught by Franazek and Reynar in the method disclosed by
`
`Sebastian in order to advantageously comparethe sizes of the block before and after compression
`
`and determinethe efficiency of the compression.

`Claims 27 and 39 are rejected under35 U.S.C. 103(a) as being unpatentable over
`
`Sebastian in view of CCITT V.42 bis or Reynar.
`
`These rejections are adopted essentially as proposed by 3PR in 3PR Request.
`
`Regarding claim 27, Sebastian discloses a method as discussed above with regard to.
`
`claim 1 but doesnotspecifically disclose that the data compression further comprises providing a
`
`compressed data block from the single compression encoder so long as the compression ratio of
`
`the compressed data block exceeds a compression threshold. Similarly, regarding claim 39,
`
`Sebastian discloses a method as discussed above with regard to claim 1 but does not specifically

`
`disclose providing a compression threshold and outputting a compressed data block that exceeds
`
`the compression threshold.
`
`However, CCITT V.42 bis teaches a system thatis related to the one described by
`
`Sebastian, including data compression. CCITT V.42 bis teaches providing a compression
`
`threshold and outputting a compressed data block that exceeds the compression threshold atleast
`
`in the sense that CCITT V.42 bis teaches determining the effectiveness of the compression and
`
`only outputting compressed data if compression would beeffective (page 11, sections 7.8-7.8.2).
`
`Reynaralso teaches a system thatis related to the one described by Sebastian, including data
`
`compression, and teaches providing a compressed data block from a compression encoder so
`
`long as the compressionratio of the compressed data block exceeds a compression threshold
`
`~ (column 18, lines 9-21; column 23, lines 10-20).
`
`Regarding claims 27 and 39,it would have been obviousto a person of ordinary skill in
`the art to provide a compression threshold and output a compressed data block that exceeds the
`
`threshold as taught by CCITT V.42 bis or Reynar in the method disclosed by Sebastian in order
`
`to ensure that resources are used for compression only when compression would beeffective.
