1 C. FINDINGS OF FACT
2 The following findings of fact are believed to be supported by a
3 preponderance of the evidence. Additional findings of fact as necessary
4 appear in the Analysis portion of the opinion.
5 1. Appellants’ Specification
6 The Appellants’ invention relates generally to methods for high
7 throughput screening of lubricating oil additives and lubricating oil
8 compositions containing such additives. Specification at 1:5-6.
9 Appellants define “high throughput” as meaning that a relatively large
10 number of different lubricating oil additive compositions or lubricating oil
11 compositions can be rapidly prepared and analyzed. Specification at 5:19-
12 6:1.
13 The compositions can be analyzed for storage stability such as, e.g.,
14 sedimentation data, color data, and viscosity data. Specification at 20:13-16.
15 One test for measuring storage stability includes determining how
16 much light can pass through or be scattered by a sample of the lubricating oil
17 additive composition or lubricating oil composition. Specification at 22:1-3.
18 Alternatively, a viscosity test may be used to determine storage
19 stability. Specification at 24:20-21.
20 The base oil of the lubricating oil compositions of the invention may
21 be any natural or synthetic lubricating base oil. Specification at 11:16-18.
22 The lubricating oil additive compositions of the invention include at
23 least one lubricating oil additive that can be any presently known or later-
24 discovered additive used in formulating lubricating oil compositions.
25 Specification at 6:18-21.
