The Invention
1. As depicted in Figure 1, Appellants invented a network transceiver
(100) operable in either an industry-compliant mode or in a custom
mode. The transceiver (100) includes an encoder (120), a decoder
(125) and a mode controller (130) to control the operating modes of
the transceiver. (Specification 11-12.)
2. The controller (130) comprises an encoder portion (135) and a
decoder portion (140). The encoder portion (135) being able to direct
the encoder (120) to encode received data in either the industry
compliant mode or the custom mode. (Id. 13.)
3. When the detector senses received data to be in a custom mode, the
decoder portion (1) directs the encoder portion to direct the encoder to
encode the data in custom mode, and (2) directs the decoder to decode
the received custom data. (Id.)
The Prior Art Relied Upon
4. As depicted in Figure 1, Herve teaches a dual-mode ISDN/STN
visiophone terminal including an audio section (7) and a video section
(1). Each of the videophone sections is connected to a respective
CODEC segment (13, 24, 6, and 25) to encode or decode received
data according to the ISDN or STN mode of operation that the
management system (18) selected via a switch (28). (Col. 3, ll. 19-65;
col. 4, ll. 12-23.)
ANALYSIS
We begin our analysis by noting that independent claims 1, 9, 18 and
26 require a controller comprising an encoder portion and a decoder portion
wherein the decoder portion directs the encoder portion to direct an encoder
