Appeal No. 1999-2406 Application No. 08/825,256 Accordingly, we cannot uphold the examiner's rejection under 35 U.S.C. § 112, first paragraph, of claims 1 through 4, 10, 11, 20, and 21 as violating the written description requirement. Concerning the rejection under 35 U.S.C. § 112, first paragraph, of all the appealed claims as failing to comply with the enablement requirement, we agree with the appellants (appeal brief, pages 12-13; reply brief, pages 2-5) that one skilled in the relevant art would not be subject to any undue experimentation to make and/or use the claimed invention.2 Here, the specification contains explicit direction or guidance on how "to minimize the effects of surface tension" or "to cancel out surface tension of the solution." (E.g., page 5, lines 19-24; page 7, line 10 to page 11, line 23.) This direction or guidance is accompanied by actual working examples and drawings to further enlighten one skilled in the relevant art. 2 The question of whether making and using the invention would have required "undue experimentation" depends on several underlying factual inquiries including: (1) the quantity of experimentation necessary; (2) the amount of direction or guidance presented; (3) the presence or absence of working examples; (4) the nature of the invention; (5) the state of the prior art; (6) the relative skill of those in the art; (7) the predictability or unpredictability of the art; and (8) the breadth of the claims.
