In Re Stepan Co.
The principal issue here is whether the Board of Patent Appeals and Interferences (“Board”), in affirming an examiner’s ruling on reexamination that a patent was invalid as obvious, relied on a new ground of rejection, i.e., a rejection that the examiner had not explicitly made. If the Board
I. Background
The appellant Stepan Company (“Step-an”) is the assignee of U.S. Patent No. 6,359,022 (“'022 patent”). The patent covers polyol-based resin blends and the methods of using them to create closed-cell polyurethane and polyisocyanurate-based foam. Such foams are used, for example, to make thermal insulation boards for the walls of homes and buildings.
On reexamination, the examiner ruled that all the claims of the '022 patent were invalid as anticipated under
In relying on Singh as
Stepan timely appealed the Board’s decision to this court. We have jurisdiction pursuant to
II. Legal Standard
Whether the Board relied on a new ground of rejection is a legal question that we review de novo.
See In re Pacer Tech.,
In a series of opinions, both this court and our predecessor court, the United States Court of Customs
&
Patent Appeals (“Patent Court”), have recognized that if the appellant has not had a full and fair opportunity to litigate the Board’s actual basis of rejection, the administrative validity proceedings before the United States Patent and Trademark Office (“PTO”) should be allowed to continue.
See In re Kumar,
The rationale of those decisions is that unless the appellant was able to address the merits of the various bases of the Board’s decision, the administrative proceedings before the PTO should be allowed to continue. As the governing regulation states, “[s]hould the Board have knowledge of any grounds not involved in the appeal for rejecting any pending claim, it may ... [issue] a new ground of rejection.”
III. Discussion
On appeal, Stepan argues that the Board sustained the examiner’s obviousness rejection under a wholly different basis than that relied upon by the examiner, which constitutes a new ground of rejection. It contends that the Board’s determination that Singh is
The PTO responds that the Board’s decision is not a new ground of rejection because the thrust of the rejection was the same, i.e., obviousness. It argues that Stepan had a fair opportunity to be heard because it did in fact present argument and evidence, which was considered by the Board, to antedate Singh as a
Stepan is correct. By making and relying on new fact findings regarding an issue the examiner did not raise, i.e., the sufficiency of Stepan’s Declaration to swear behind the Singh reference as
The PTO’s alternative rationale is that Stepan waived its administrative due process rights by failing to exhaust all administrative remedies — namely—by failing request a rehearing.

The PTO reasons that
We disagree for two reasons. First, the PTO’s regulatory interpretation is due no deference in view of the agency’s statutory obligation under the Administrative Procedure Act (“APA”) to provide prior notice to the applicant of all “matters of fact and law asserted” prior to an appeal hearing before the Board.
Second, the PTO’s argument that Step-an was obligated to request rehearing under
IV. Conclusion
Notice does not focus on the applicant’s arguments divorced from the examiner’s rejections of record that are actually appealed to the Board. Instead, it focuses on the “adverse decisions of examiners” during prosecution which form the basis of the Board’s scope of review.
