Reexamination Control No. 90/005,742
Patent 5,253,341
1 The§ 112 rejection is based on testimony by Dr. Koopman concerning a Bridges article
2 that is cited in the '341 patent for its disclosure of differential compression and is also relied on
3 by the examiner in a § 103(a) rejection of claims 94 and 97 (i.e., for obviousness over Cohen in
4 view of Bridges and Punj). 2d Action at 21, para. 43; 3d Action at 92, para. 28; Final Action at
5 248, para. 28. The pertinent part of the '341 patent reads:
6 Furthermore, in order to accommodate efficient compression and
7 decompression of animated sequences (as in feature film video), a
8 technique of Differential (DFF) Image Compression (DIC), as described
9 in an article by John Bridges in Dr. Dobb's Journal #173 February 1991,
10 page 38, et seq may utilized as part of the decompression module.

12 '341 patent, col. 7, ll. 34-40.48 The '341 patent explains that Bridge's differential compression
13 techniques can be used for communications over a high band-width channel (e.g., CATV), col. 7,
14 l. 53 to col. 8, l. 12, or over a standard DDS telephone line. Id. at col. 8, ll. 13-23.
15 Cohen (described in more detail below in the discussion of the rejection) discloses a
16 system which employs telephone lines or a fiber optic cable network to send movies from a
17 central location to a subscriber site. Cohen, col. 4, ll. 41-46; claims 2 and 3. The § 103(a)
18 rejection characterizes Bridges as "disclos[ing] a system for compressing upon transmission to
19 allow for realtime display of the transmitted video." 2d Action at 22, para. 46; 3d Action at 93,
20 para. 31; Final Action at 248, para. 31. In his first declaration, Dr. Koopman disagreed with the
21
22 examiner’s characterization of Bridges for the following reasons, which the examiner now cites
23 as the basis for the § 112 non-enablement rejection:
