Appeal No. 1998-2045 Application 08/402,374 view that in order for several different references to be cited as conventional features of a transistor, the transistors of the several references should all have similar operating ranges, device sizes and device materials. In other words, a conventional feature of a transistor operating under one condition would not necessarily be a conventional feature of a different transistor operating under different conditions. Of particular concern to us is the difference in the range of voltages in which Morozumi, Asars and Togashi are designed to operate and the differences in the semiconductor channel materials. Morozumi describes a liquid crystal device operating at about 10 volts [column 8, lines 26-43; column 11, line 48]. Asars describes a liquid crystal device operating at about 80 volts [column 5, lines 10-12]. Togashi describes a liquid crystal device operating at about 40 volts [page 3, line 113]. Thus, the first thing we note is that the liquid crystal devices of Morozumi, Asars and Togashi are designed to operate at substantially different voltage levels. Morozumi, like the claimed invention, has a channel 13Page: Previous 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 NextLast modified: November 3, 2007
