Appeal No. 1997-2510 Application No. 07/868,539 the specification. See, e.g., 1 Donald S. Chisum, Chisum on Patents Section 3.02 [1] & n.12 (rel. Dec. 1996) ("The line between interpreting claim language in light of the specification and reading a limitation from the specification into the claim is a fine one."). However, in our opinion, by reference to Figure 4, appellant is merely providing exemplary sequences that “correspond to a sequence of DNA recognized by a viral-specific transcription factor” (see Specification, page 7, description of Figure 4). Therefore, in our opinion, when the claims are read in light of the specification, a person of ordinary skill in the art would reasonably understand what is intended by the phrase “corresponds to a sequence of DNA recognized by a viral-specific transcription factor”. Claim 7: According to the examiner (Answer, bridging paragraph, pages 4-5): In claim 7 … the “one region” (second to last line) is indefinite as to the end where X1 is covalently attached is the 3’ end of X1 … attached to the … 3’ end of the “one region” (is it the first region or the second region that is referred to as the ‘one region’? Similarly, the [sic] it is not clear as to whether the “and X4 is covalently attached refers to the 5’ end of X4; attached to the 5’ end of the “other region”.

In response, appellant argues (Brief, page 26) that “[t]he claim refers to two regions of DNA which are joined by a linker in the 5’ to 3’ direction.
