rate is important to the selected end use, a composition without
metal drier should be cured at elevated temperature.” Brief,
p. 4, para. 2. We disagree. We find nothing in the referenced

understood the phrase as suggesting an elevated temperature, they
have not provided any evidence which supports that position.

Answer, p. 4. Accordingly, the examiner concludes that

were] used in the known method of making end-blocked
