Appeal No. 1999-0197 Application 08/054,970 Absent a fact-based explanation from the examiner why the experimentation required to practice the methods set forth in the use claims on appeal would be undue rather than routine, we conclude that the examiner has not established a prima facie case of lack of enablement. The examiner’s rejection is reversed. Other Issues 1. p75-TNF-R. As explained above, the present invention involves two distinct tumor necrosis factor receptors, i.e., p55–TNF-R and p75-TNF-R. The vast majority of the disclosure in this application is directed to the p55 receptor. The most illuminating discussion of the p75 receptor in the specification appears at page 29 where appellants state: Although reference is made throughout to the p55-TNF-R, it is evident from what is known of the p75-TNF-R, that it functions similarly. Therefore the present invention encompasses modulation of the signal transduction and/or cleavage in both known TNF receptors. Some of the claims on appeal contain an embodiment directed to the p75-TNF-R. For example, claim 34 first references a molecule which binds to the portion of TNF-R which includes certain amino acids of human p55-TNF-R or “the corresponding amino acids of the human p75-TNF-R.” It does not appear from the record that the examiner has paid attention to this alternative embodiment. Upon return of the application, the examiner should review all of the claims pending and ensure that the subject matter of each claim has been fully examined.
