ON PETITION FOR REHEARING
PER CURIAM.
The Patent Office petitions for rehearing or, in the alternative, vacation of our decision and remand "for consideration of the pertinent technical authorities."
The issue on which our decision of May 13, 1971, rests is obviousness under 35 U.S.C. § 103. (58 CCPA 1192, 441 F.2d 664, 169 USPQ 602.) That issue turned on whether appellant obtained unexpected results, particularly in reduction of the heat produced during operation of the motor. On the question of the expectedness of heat reduction, the prior art relied on by the Patent Office shed little if any light. In struggling with the question of the predictability of heat reduction by the structure claimed by appellant, and finding no help in the art of record, we referred to a textbook outside the record in which we found certain matter leading us to conclude in favor of unpredictability and hence unobviousness.
The Patent Office brief in support of its petition contests the validity of our reasoning and cites other parts of the textbook we relied on together with several additional authorities not of record in this application, on the basis of which it strongly urges that reduction of heat would have been entirely predictable to one of ordinary skill in the relevant art.
We do not consider that we should pass on the validity of the technical arguments in the solicitor's brief, based on these newly cited authorities, until (1) the examining branch of the Patent Office has done so and (2) appellant has been afforded an opportunity to consider these authorities and reply to their application against him. The case is not an appropriate one for a rehearing because the Patent Office now wishes to rely on several references not of record.
As to the Patent Office request for remand, we note it wishes to consider "pertinent technical authorities," not now of record, first cited in its brief on the petition. As we have often pointed out, we pass only on rejections actually made and do not decree the issuance of patents. After our decision in an ex parte patent case, the Patent Office can always reopen prosecution and cite new references, in which limited sense our mandates amount to remands. However, in the unusual circumstances of this case we will explicitly answer the petition by remanding the case to permit inclusion in the record of further evidence, by either the Patent Office or the applicant, on the issue of obviousness.
Remanded.
