Reexamination Control No. 90/005,742
Patent 5,253,341
1 consideration. The examiner correctly notes that Filepp teaches a windowing environment in
2 column 8, line 64 to column 9, line 57, which explains that Figures 3a and 3b show the
3 information being displayed in a windowing format at the client machine (RS 400). 3d Action at
4 83, para. 17. Dr. Koopman's criticism that these displays appear at the client machine rather than
5 at the server (2d Koopman Decl. at 171, para. 362) incorrectly construes the claim as requiring a
6 window display at the server.
7 The § 103(a) rejection of claim 14 for obviousness over Filepp in view of Row is
8 affirmed.
9 (5) Claim 11 – obvious over Filepp in view of Giltner?
10 Claim 11 differs from claims 9 and 10 by not including UNIX, RISC, or CISC limitations
11 and instead specifying that the compressed response received from the remote server "is
12 compressed utilizing at least two compression techniques."
13 Filepp’s compressed response received from the server includes a compression descriptor
14 segment containing the information needed for the decompression of objects compressed in
15 interactive network 10, such as Huffman coding, and more particularly includes parameters to be
16 used by a decompression routine residing at the reception system 400. Filepp, col. 15, ll. 35-41.
17 Giltner discloses a system which compresses data for transmission over a conventional
18 telecommunications network and performs decompression at a remote station. Giltner, col. 1, ll.
19 6-13. As explained in the abstract, on which the examiner relies, the system can be used with
20 text data or other types of data, serial or parallel, such as color television data. The system is
21 useful when the number of possible data units (e.g., words in the English language) is very large.
