Appeal No. 94-2232 Application 07/888,367 supervision and direction of Kroger.” Id. at 371. The Board stated at 371-372: If this were all the evidence in this case, then we would be constrained to agree that Kroger et al are the inventors and that Knaster is not a coinventor. The difference in Kroger was that the record included additional evidence which showed that (1) Knaster refused to sign a declaration that he was not a coinventor, and (2) Knaster wrote a letter to the PTO declaring himself to be a coinventor of the invention claimed. In this case, we have only an examiner’s speculation that Lee must be a coinventor of the subject matter claimed in this application because of the repeated use of the pronoun “we” in the later published papers which Lee co-authored and coinventor Raikhel’s reference to “Dr. Lee” in her declaration (Supplemental Examiner’s Answer, pp.2-4). However, the examiner may recall that the PTO was expressly cautioned against just this type of speculation in In re Katz, 687 F.2d at 455-56, 215 USPQ at 18 (emphasis added): 19Page: Previous 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 NextLast modified: November 3, 2007
