Reexamination Control No. 90/006,696
1 that purpose. Aszodi at 1127, Abstract. One of these materials is 8CB
2 (a.k.a. K24), one of the liquid crystal materials recited in Claim 11; the other
3 is 80CB (a.k.a. M24), which is not recited in the claim.
4 2. Figure 1, id. at 1128, is a graph showing that the clearing point
5 (i.e., nematic-isotropic transition) temperature of the mixture is a linear
6 function of the proportions of M24 (80CB) and K24 (8CB). The left end
7 point of the graph represents 100 mole percent of 8OCB (M24) and shows a
8 transition temperature of about 80 ºC. The right end point represents 100
9 mole percent of 8CB (K24) and shows a transition temperature of about
10 40 ºC. Thus, neither end point represents a mixture.
11 3. The caption under Figure 1 explains that the small circle on the
12 line representing the nematic-isotropic transition temperature corresponds to
13 a specific example of a mixture containing 60 mole percent 8CB (i.e., K24)
14 and 40 mole percent of 8OCB (i.e., M24). Id.
15 4. Figure 2 (at 1128) demonstrates that the liquid crystal material
16 appears to be dark when it is in the isotropic phase (i.e., its temperature is at
17 or exceeds the nematic-isotropic transition temperature).
18 5. Aszodi describes an experiment in which the M24/K24 mixture is
19 used for thermal mapping of “a chip . . . from a commonly manufactured
20 LED with an octagonal active area.” See sentence bridging pages 1128 and
21 1131 (page 1129 consists of Figure 5; page 1130 is blank). Figure 4 (id.
22 at 1131) illustrates the structure of the LED. Aszodi does not characterize
23 this LED as being a failed or defective device.
24 6. Figure 5 (at 1129), which is nearly illegible in the photocopy of
25 record, depicts a photomicrograph obtained during the experiment. The
26 caption under this figure reads:
