Appeal No. 2004-2317 Page 20 Application No. 09/771,938 plant produced by growing a seed of the corn variety I015036 has an SSR profile which is the same as that shown in Table 6. Therefore, it is unclear to this panel why the examiner believes that such a disclosure fails to provide adequate written descriptive support for the claimed invention.14 Accordingly, we are not persuaded by the examiner’s argument. Regarding the isozyme typing profile, the examiner finds (Answer, page 18), “Table 7 provides names of loci where isozyme markers reside, for three different corn plants, and a numerical value that represents the numbers of alleles at isozyme loci types. The nucleotide sequences that make up these loci are not described.” In response, appellant points out (Brief, page 26), the isozyme “markers are well known and isozyme analysis in general [is] very well known having been used for decades.” In this regard, we remind the examiner that the inquiry into whether the description requirement is met must be determined on a case-by-case basis and is a question of fact. In re Wertheim, 541 F.2d 257, 262, 191 USPQ 90, 96 (CCPA 1976). A description as filed is presumed to be adequate; unless or until sufficient evidence or reasoning to the contrary has been presented by the examiner to rebut the presumption. See e.g., In re Marzocchi, 439 F.2d 220, 224, 169 USPQ 367, 370 (CCPA 1971). The examiner, therefore, must have a reasonable basis to challenge the adequacy of the written description. Accordingly, it is the examiner who has the initial burden of establishing by a preponderance of evidence that a person 14 We are not persuaded by the examiner’s assertion (Answer, page 28) “that the [commercially available] service used to detect SSR markers is currently available is not a guarantee that it will remain so for the life of a patent issuing from the application.” Cf.
