C. FINDINGS OF FACT
The following findings of fact are supported by a preponderance of
the evidence. Additional findings of fact as necessary appear in the Analysis
portion of the opinion.
1. Colclough 579
Colclough 579 discloses lubricant compositions, especially
automobile crankcase lubricants, containing low or zero amounts of
phosphorous. Colclough 579 at 2:3-4.
The disclosed lubricant compositions contain small amounts of
phosphorous, i.e., less than 0.05 weight percent, preferably less than 0.01
weight percent, more preferably less than 0.005 weight percent, but more
preferably the lubricating compositions are substantially free of phosphorus.
Colclough 579 at 4:32-34.
Colclough 579 provides examples of the invention as well as
comparative examples. Colclough 579 at 6:55-7:21.
Colclough 579 explains that the results reported in these examples
show that the lubricants of the invention provide excellent antioxidant, anti-
wear, and bearing corrosion inhibition with substantial absence of
phosphorous. Colclough 579 at 7:22-24.
2. Colclough 580
Colclough 580 discloses lubricant compositions, especially
automobile crankcase lubricants, containing low or zero amounts of
phosphorous. Colclough 580 at 2:3-4.
The disclosed lubricant compositions contain small amounts of
phosphorus, i.e., less than 0.01 weight percent, preferably less than 0.005
