`
`Patent 7,161,506 B2
`
`This proceeding arose from a third party request on behalfof Blue
`
`Coat Systems, Inc. for an inter partes reexamination of U. S. Patent
`
`7,161,506 B2 (the ‘506 patent), entitled “Systems and Methods for Data
`
`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
`
`presently stand rejected. Claims 6, 7, 16, 41, and 42 have been confinned.
`
`We have jurisdiction under 35 U.S.C. §§ 134(b) and 306.
`
`STATEMENT OF THE CASE
`
`The ‘506 patent describes “data compression and decompression
`
`using content independent and content dependent data compression and
`
`decompression” (col. 6, 11. 21-23).
`
`Claim 1 on appeal reads as follows:
`
`(App. Br. 44, Claims Appendix.)
`
`1. A method for compressing data, comprising the steps of:
`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.

`
`(e) the invention was described in (1) an application for patent, published under section 122(b), by another filed
`in the United States before the invention by the applicant for patent or (2) a patent granted on an application for
`patent by another filed in the United States before the invention by the applicant for patent, except that an
`international application filed under the treaty defined in section 351(a) shall have the effects for purposes of this

`
`Regarding claim 1, Sebastian discloses a method for compressing data, comprising the
`
`steps of:
`
`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 (i.e., using
`
`elements including filters lOa—z and filter selection system 22 in encoder 3; column 1, lines 50-
`
`52; column 2, lines 1-42; column 3, lines 66-67; column 4, lines 1-25);
`
`performing content dependent data compression, if a data type of the data block is
`
`identified (column 2, lines 33-42, column 5, lines 14-18; column 6, lines 22-40);
`
`performing data compression with a single data compression encoder, if a data type of the
`
`(column 2, lines 43-47; column 3, lines 37-41).
`
`data block is not identified (i.e., Sebastian discloses a generic compression system; column 1,
`
`lines 55-60; column 4, lines 9-20).
`
`Regarding claims 2-4, Sebastian discloses appending a data compression type descriptor
`
`to a compressed data block and outputting the compressed data block with the appended data
`
`compression type descriptor (column 3, lines 31-36; column 5, lines 14-18).
`
`Regarding claim 5, Sebastian discloses that the performing content dependent data
`
`compression further comprises enabling at least one encoder associated to the data type to
`
`compress the data block (column 1, lines 55-57; column 2, lines 33-42).
`
`Regarding claim 8, Sebastian discloses that the performing content dependent data
`
`compression further comprises compressing the data block with cascaded encoders that are
`
`associated to the data type (column 17, lines 15-28; column 19, lines 31-48).
`
`Regarding claim 9, Sebastian discloses that the content dependent compression is lossless
