Reexamination Control No. 90/005,742
Patent 5,253,341
1 technique of Differential (DFF) Image Compression (DIC) described by John Bridges in Dr.
2 Dobb's Journal #173 February 1991, page 38, et seq. (the Bridges reference) may utilized as part
3 of the decompression module. Id. at col. 7, ll. 34-40. Improved (maximum) compression be
4 obtained by combining the DIC methodology for DFF frames with a high compression ratio
5 methodology for reference frames, such as the FRACTAL technique. Id. at col. 8, ll. 13-18.
6 Alternatively, a combination of compression technologies may be used “to communicate a
7 reasonable quality video single animated sequence over a lower bandwidth channel such as the
8 standard DDS phone lines, in real time, where the data rate is effectively 1600 bytes per second
9 or above.” Id. at col. 8, ll. 18-23.
10 F. The rejected claims
11 Claims under reexamination are given their broadest reasonable interpretation consistent
12 with the patent disclosure. In re American Academy of Science Tech Center, 367 F.3d 1359,
13 1364, 70 USPQ2d 1827, 1830 (Fed. Cir. 2004).
14 The rejected claims include ten independent claims, viz., claims 9-11, 14, 93, and 100-04.
15 As already noted, claims 9-11 and 14 specify that the response received by the remote query and
16 data retrieval means from the remote host is compressed. The remaining independent claims
17 specify that the response may be compressed or non-compressed. Claim 9 reads:
18 9. Apparatus for querying and downloading data from a remote server
19 comprising:
20
21 end user means for formulating a query via a data input means and
22 inputting said query to remote query and data retrieval means;
