Interference No. 103,352 explanatory and must be discussed with particularity by a witness. 37 CFR 1.671(f); Rebstock v. Flouret, 191 USPQ 342, 345 (Bd. Pat. Int. 1975). Since only the inventors testified as to exhibits KX 3-5, we find that those exhibits do not constitute sufficient circumstantial evidence of an independent nature to satisfy the corroboration rule. With regard to the analytical report from Robertson Laboratory (KX-6), it too has not been discussed with particularity by a witness other than inventor Khokhar (KR-16). Although non-inventor Oeckinghaus did testify for the purpose of authentication, she did not discuss any of the circumstances surrounding the entries made in the report. Thus, the analytical report also does not constitute sufficient circumstantial evidence of an independent nature to corroborate synthesis of a compound within the scope of the count. Moreover, an elemental analysis alone is generally not definitive with regard to identification of a specific compound. Cf. Berges v. Gottstein, 618 F.2d at 774, 205 USPQ at 694.
