Interference No. 104,241 al.'s burden) with the requirements for what constitutes a constructive reduction to practice. Suffice it to say that Cupps et al. are the senior party in this interference because their benefit application serves as a constructive reduction to practice of the subject matter defined by the count. See Kawai v. Metlesics, 480 F.2d at 886, 178 USPQ at 163. Accordingly, for all the above reasons, the motion under 37 C.F.R. § 1.633(g) is DENIED. Because Jeon et al.'s motion has been denied, we must now determine whether or not the order to show cause was properly issued by the APJ. THE ORDER TO SHOW CAUSE As the party with the burden of persuasion under 37 C.F.R. § 1.608(b), Jeon et al. had the burden to establish that they were prima facie entitled to judgment relative to Cupps et al. In order to establish they were prima facie entitled to judgment, Jeon et al. was required to prove at least so much of their case as would entitle them to an award of priority assuming that Cupps et al. relied solely on their filing date and were not to rebut any of Jeon et al.'s case.
