Petitioner Must Show Actual Injury to Establish Standing to Appeal PTAB Final Written Decision

Jan 17, 2017

Reading Time : 2 min

Phigenix, the party seeking judicial review, bears the burden to establish standing.  To prove standing, Phigenix must establish that (1) it suffered an injury in fact, (2) the injury is fairly traceable to challenged conduct of ImmunoGen, and (3) the injury is likely to be redressed by a favorable judicial outcome. First, the Federal Circuit addressed threshold issues of the burden of production, evidence to meet that burden, and when the evidence must be produced in cases where the appellant seeks review of final agency actions and its standing is challenged. The appellant’s burden of production is the same as a plaintiff moving for summary judgment in district court. An appellant is permitted to supplement the administrative record with arguments, affidavits or other evidence to demonstrate its standing, if the appellant’s standing is not self-evident (i.e., the appellant is not “an object of the action (or forgone action) at issue.”). Sierra Club v. EPA, 292 F.3d 895, 900 (D.C. Cir. 2002) (quoting Lujan v. Defs. Of Wildlife, 504 U.S. 555, 561-62 (1992)). Finally, if there is no evidence on the record to support standing, the appellant must provide evidence establishing its standing at the earliest possible opportunity because standing involves threshold questions over the court’s authority to hear the dispute.  

The Federal Circuit held that Phigenix did not have standing to appeal the PTAB decision in federal court because it failed to establish that it suffered an injury. Phigenix asserted that although it does not face the risk of infringing the ’856 patent, it has suffered actual economic injury because the ’856 patent increases competition between Phigenix and ImmunoGen for licensing revenue. The Federal Circuit held that the documents and declarations Phigenix relied on to support its claim are insufficient to show injury in fact because they are merely a conclusory statement about a hypothetical licensing injury and do not establish that Phigenix ever licensed the ’534 patent to anyone, let alone to entities that obtained licenses to ImmunoGen’s ’856 patent. Phigenix’s remaining arguments that it suffered an injury based on the estoppel effect of the PTAB’s decision and the violation of its procedural right to seek an appeal under 35 U.S.C. § 141 (c) were also denied. Thus, Phigenix’s appeal of the PTAB’s decision was dismissed.

The Federal Circuit recently addressed whether the PTO must conduct notice‑and‑comment rulemaking before issuing instructions that guide how the Board should exercise discretion at the institution stage of IPRs. The court held that no such rulemaking is required. Instructions to the Board regarding its use of the Director’s delegated discretionary authority not to institute review are merely general statements of policy exempt from notice-and-comment rulemaking.

The District Court for the District of Delaware recently invalidated claims directed to a panoramic objective lens for lack of enablement, holding the claims impermissibly recited a single element in means‑plus‑function form. Under § 112, ¶ 6, “[a]n element in a claim for a combination may be expressed as a means or step for performing a specified function….” By its plain terms, the statute permits means‑plus‑function claiming only in the context of a “combination.” In other words, a claim may not consist solely of a single means‑plus‑function element. Claims drafted as a single means are invalid for lack of enablement as a matter of law.
