Chief Judge Sleet denies motion to exempt trial attorney from prosecution bar

Chief Judge Sleet recently denied a plaintiff’s request to modify a protective order to exempt its lead trial attorney from a prosecution bar. In re Bear Creek Technologies Inc. (‘722 Patent Litigation), MDL No. 12-2344 (GMS) (D. Del. July 25, 2012). The Court explained that “where a separate court [here, the Eastern District of Virginia] has already found that a party met its burden with respect to the need for a prosecution bar on reexamination proceedings, as Verizon has done here, the burden shifts to the other party to prove an exemption on a counsel-by-counsel basis[.]” Id. at 3 (citing In re Deutsche Bank Trust Co. Ams., 605 F.3d 1373 (Fed. Cir. 2010) (alteration added)). Proving that an exemption is needed “requires demonstrating that: (1) counsel’s representation of the client in matters before the PTO does not and is not likely to implicate competitive decision-making related to the subject matter of the litigation so as to give rise to a risk of inadvertent use of confidential information learned in litigation; and (2) the potential injury to the moving party from restrictions imposed on its choice of litigation and prosecution counsel outweighs the potential injury to the opposing party caused by such inadvertent use[.]” Id. at 4.

The Court denied the plaintiff’s motion, explaining that the plaintiff failed to satisfy its burden of showing “(1) that [its lead trial attorney’s] involvement in the … Reexamination will not implicate competitive decision-making[]; and (2) even if [he] would not be involved in such decision-making, that the potential injury to [the plaintiff] in precluding its choice of counsel outweighs the potential injury to Verizon that would result from inadvertent confidential disclosure(s)[.]” The Court noted that, as the Federal Circuit has held, “strategically amending or surrendering claim scope during prosecution can implicate competitive decision-making necessitating a denial of an exemption request.” Id. at 5 n.6. Further, the Court noted that as a result of discovery under the protective order, the plaintiff’s lead trial attorney already had developed “in-depth knowledge of Verizon’s highly confidential information on nearly all aspects of its voice telecommunications network …” Id. at 5 n.7 (internal quotation marks omitted). On balance, the Court found that exempting the plaintiff’s lead trial attorney from the prosecution bar was unwarranted in light of the knowledge he already had gained through the litigation, coupled with the significant harm Verizon would incur through any inadvertent disclosure. Id. at 6 n.7.
