Opinion

RICH, Circuit Judge.

Kenneth A. Barton and Michael J. Miller appeal from a judgment of the Board of Patent Appeals and Interferences (Board) entered against Barton et al. in a three-party interference as to the subject matter in claims 1-4, 7, and 15-22 of the Barton et al. application designated as corresponding to a single count of the interference. Because we find that the Board abused its discretion, we reverse and remand.

Background

The Board declared a three-party interference on November 7, 1996, between the following two pending patent applications, whose owners were deemed junior parties, and an issued patent, whose owner was deemed the senior party, listed as follows:

(1) Serial No. 07/827,906, entitled “Improved Expression of Genes in Plants,” filed by Kenneth A. Barton and Michael Miller, assigned to Agracetus (Barton et al.);
(2) Serial No. 08/434,105, entitled “Synthetic Plant Genes and Method for Preparation,” filed by David A. Fischhoff and Frederick J. Perlak, assigned to Monsanto Company (Fischhoff et al.);
(3) U.S. Patent No. 5,380,831, entitled “Synthetic Insecticidal Crystal Protein Gene,” filed by Michael J. Adang, Thomas A. Rocheleau, Donald J. Merlo, and Elizabeth E. Murray and assigned to Mycogen Plant Science, Inc. (Adang et al.).

The subject matter of the interference relates to introducing into plants genes that encode bacterial proteins from B. thuringien-sis that are selectively toxic to insects so that the plant cells produce the bacterial insect toxin and are protected from insects that feed on them. More specifically, the count relates to designing modified genes from B. thuringiensis to be more highly expressed in plant host cells. The Board assigned only a single count in the interference, which reads as follows:

A method of designing a synthetic Bacillus thuringiensis gene to be more highly expressed in plants, comprising the steps of:
a) analyzing the coding sequence of a gene derived from a Bacillus thuringien-sis which encodes an insecticidal protein toxin, and modifying a portion of said coding sequence to yield a modified sequence which contains a greater number of codons preferred by the intended plant host than did said coding sequence, or
b) analyzing the coding sequence of a gene derived from a Bacillus thuringien-sis which encodes an insecticidal protein *1142 toxin, and modifying a portion of said coding sequence to yield a modified sequence which contains a greater number of codons preferred by the intended plant host than did said coding sequence and fewer plant polyadenylation signals than said coding sequence.

The Board stated that all pending claims 1-4, 7, and 15-22 of the Barton et al. application were assigned to the count, claims 3, 5, 39-43 of the Fischhoff et al. application were assigned to the count, and all claims 1-14 of the Adang et al. patent were assigned to the count.

Shortly after the Board’s declaration of the interference, Monsanto bought Agracetus, the owner of the Barton et al. application, and filed a notification of ownership of the entire right, title, and interest in both the Barton et al. and the Fischhoff et al. applications only two weeks after the interference had been declared. Monsanto stated in its notification that good cause existed for continuing the interference between all three parties pursuant to 37 C.F.R. § 1.602(a) because the precise content of the count in an interference is subject to change following preliminary motions, which were not yet due, and the inherent legal uncertainties involved in priority determinations in biotechnology concerning the possible application of a simultaneous conception and reduction to practice rule made it impossible for Monsanto to choose the best application with which to defend the interference.

Adang et al. countered that Monsanto had not shown good cause to continue the interference with both the Fischhoff et al. and Barton et al. applications because the interests of Fischhoff et al. and Barton et al. were no longer adverse to each other, and Monsanto had all available information to make an informed decision of priority between the two commonly owned applications. In response, Monsanto stated that a public interest exists in deciding all of the issues among parties in interest relating to a single patentable invention in a single inter partes proceeding before the Board.

The Board found that Monsanto had not shown good cause why the interference should be continued with both of the commonly owned applications, and issued a show cause order why judgment should not be entered against Monsanto. Monsanto again argued that the count was indefinite, rendering it impossible for Monsanto to make a rational election between the two commonly owned applications. Monsanto asked that the imposition of the requirement that it, as the common assignee, elect between the applications be postponed until after the decisions on the preliminary motions resolving the issue of the content of the count.

The Board held that Monsanto had not shown good cause to continue the three-party interference because it had not shown that the count needed to be modified or that there were separately patentable inventions involved in either application. Based on this order, Monsanto elected to proceed with Fischhoff et al. and entry of judgment against Barton et al. was deferred until the final hearing of the interference. Monsanto petitioned the Commissioner for review of the order under 37 C.F.R. § 1.644(a)(1) and (3), asserting the same arguments of indefiniteness of the count and its uncertainty concerning the applicable legal standard for a priority determination in biotechnology eases.

Adang et al. responded that “[ejven if the count is indefinite (which it is not), there is only one invention involved in this interference and the parties — including Monsanto— know perfectly well what it is.” Also, Adang et al. responded that “[t]he burden of determining what law applies rests on Monsanto. The simultaneous conception and reduction to practice ‘rule’ is a well known concept in interference law.” Adang et al. asserted that the possibility that the content of the count will change through preliminary motions is not of the ilk of the rare circumstances for continuing the three party interference because “[ojriginal counts are often changed as the result of decisions on preliminary motions, but the changes almost always result in counts that embrace the same basic invention.”

On petition to the Commissioner, Chief *1143 Administrative Patent Judge Stoner 1 found that even if “Monsanto is correct that the count is indefinite, that supposed indefiniteness does not amount to the requisite ‘good cause.’ ... Monsanto need only compare the inventions in its own applications to decide which is prior.” Barton v. Fischhoff v. Adang,
