Appeal 1997-1635 Application 08/319,667 benzenesulfonic acid or p-toluenesulfonic acid for sulfuric acid in Actual Example 21. The use of either benzenesulfonic acid or p-toluenesulfonic acid in place of sulfuric acid in Actual Example 21 would amount to nothing more than a use of a known material for its intended purpose in a known environment to accomplish an entirely expected result. The bottom line is that Japan either anticipates or renders obvious the subject matter of claim 1. 3. Rebuttal evidence Applicants assert that if one "digs" into their specification, one will discover a showing of unexpected results. Manifestly, evidence of unexpected results is relevant in an obviousness inquiry. The examiner was not impressed. Explaining his lack of conviction with respect to applicants' showing, the examiner observes that "[t]here is no comparison between the addition of the two compounds [, i.e., the organic sulfonic acid and the amine,] 'one after the other' and/or 'jointly' as argued [by applicants] (Examiner's Answer, page 6). It is true, as the examiner held, that generally the closest prior art must be compared (id.).
