Appeal No. 1997-2510 Application No. 07/868,539 We note the examiner’s reference to In re Zletz, 893 F.2d 319, 13 USPQ2d 1320 (Fed. Cir. 1989). According to the examiner (Answer, page 5) Zletz stands for the proposition that “there is no reason to read into the claim(s) limitations of the specification….” We agree with the examiner (id.) that an “essential purpose of patent … examination is to fashion claims that are precise, clear, correct, and unambiguous. Only in this way can uncertainties of claim scope be removed, as much as possible, during the administrative process.” Zletz, 893 F.2d at 321-22, 13 USPQ2d at 1322. We note that claim language must be analyzed “not in a vacuum, but always in light of the teachings of the prior art and of the particular application disclosure as it would be interpreted by one possessing the ordinary skill in the pertinent art.” In re Moore, 439 F.2d 1232, 1235, 169 USPQ 236, 238 (CCPA 1971). Claims 1 and 6: According to the examiner (Answer, page 4) “claims 1 and 6 are unclear as to what is meant to be included or excluded by recitation of ‘whose sequence corresponds to a sequence of DNA recognized by a viral specific transcription factor’….” The examiner reasons (id.): The DNA is one single strand of DNA even where it is argued that the DNA in claim 1 is indicated as joined by traditional 5’ to 3’ phosphodiester bonds. Joining results in a single piece of DNA …. Thus, the claim is indefinite as there are no multiple fragments, but only one fragment and the metes and bounds of the first and second regions coincide and include the X1 to X4 [region].” 13Page: Previous 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 NextLast modified: November 3, 2007
