Vectura Limited v. Glaxosmithkline LLC

United States District Court, D. Delaware

April 1, 2019

VECTURA LIMITED, Plaintiff,
v.
GLAXOSMITHKLINE, LLC and GLAXO GROUP LIMITED, Defendants.

          MEMORANDUM ORDER

         Currently pending before the Court is Defendants' Motion to Strike various portions of Dr. Zhou's Declaration. (D.I. 230). I have reviewed the parties'briefing. (D.I. 231, 247, 251). The parties supplemented their briefing to address a late-filed report by Dr. Zhou. (D.I. 271. 274).

         I. BACKGROUND

         Plaintiff asserts claim 3 of U.S. Patent No. 8, 303, 991 ("the 991 patent") and claim 3 of U.S. Patent No. 8, 435, 567 ("the '567 patent") (collectively, "the Asserted Claims"). (D.I. 1). The patents-in-suit "relate to pharmaceutical compositions for inhalation and methods of making them." (D.I. 82 at 1). The asserted claims are dependent claims which cover only composite active particles made of an active ingredient and an additive material that includes magnesium stearate. (D.I. 195 at 9). The claims require that the additive material promotes dispersion of the active material for inhalation, and in the case of the '567 patent, delays dissolution of the active material. (See D.I. 169 at 2).

         On August 10, 2018, the parties made various motions for summary judgment. (D.I. 120, 122, 126). On October 1, 2018, I issued my claim construction opinion, and subsequently, the claim construction order. (D.I. 167; D.I. 169). The parties had exchanged expert reports prior to the opinion, and my constructions of the claim terms differed from that of either party. I then permitted supplemental expert discovery between the parties and amended summary judgment briefing. (D.I. 176). The parties have exchanged supplemental expert discovery and amended their previous summary judgment briefing.

         During the amended summary judgment briefing, Plaintiff attached a declaration from its infringement expert, Dr. Zhou, to its opposition brief to Defendants' motion for summary judgment of noninfringement. (D.I. 211). Defendants have filed a motion to strike portions of that declaration as untimely new opinion. (D.I. 230). On March 22, 2019, Plaintiff then filed a sur-reply report from Dr. Zhou. Defendants then filed a letter requesting that the new report be addressed with Dr. Zhou's declaration. (D.I. 271).

         II. LEGAL STANDARD

         Federal Rule of Civil Procedure 37(c)(1) provides that "[i]f a party fails to provide information ... as required by Rule 26(a) or (e), the party is not allowed to use that information .. . to supply evidence on a motion, at a hearing, or at trial, unless the failure was substantially justified or is harmless." To determine whether a failure to disclose was harmless, courts in the Third Circuit consider the Pennypack factors: (1) the prejudice or surprise to the party against whom the evidence is offered; (2) the possibility of curing the prejudice; (3) the potential disruption of an orderly and efficient trial; (4) the presence of bad faith or willfulness in failing to disclose the evidence; and (5) the importance of the information withheld. Konstantopoulos v. Westvaco Corp., 112 F.3d 710, 719 (3d Cir. 1997) (citing Meyers v. Pennypack Woods Home Ownership Ass 'n, 559 F.2d 894, 904-05 (3d Cir. 1977)). "[T]he exclusion of critical evidence is an 'extreme' sanction, not normally to be imposed absent a showing of willful deception or 'flagrant disregard' of a court order by the proponent of the evidence." Id. The determination of whether to exclude evidence is within the discretion of the district court. Id.

         III. DISCUSSION

         Defendants move to strike the last sentence of paragraph 14 and paragraphs 15 and 22-27 from Dr. Zhou's Declaration. Defendants assert that Dr. Zhou's declaration introduces new expert opinions and contradicts his prior testimony. (D.I. 231 at 6). More specifically, Defendants assert that the declaration offers new opinions that should have been disclosed in Dr. Zhou's supplemental expert report as the new opinions are supported by evidence that was available to Dr. Zhou at the time of his opening supplemental report. (Id.). Plaintiff asserts that Dr. Zhou's declaration does not offer new opinions. (D.I. 247 at 7). In the alternative, Plaintiff argues that to the extent any new opinions were offered, the Pennypack factors weigh against exclusion of those opinions. (Id. at 11).

         First, I do not understand the last sentence of paragraph 14 of Dr. Zhou's declaration to offer an improper new opinion. Rather, in paragraph 14, Dr. Zhou reiterates his opinions from his supplemental report "and elaborated on how he had reached that opinion by providing greater detail. . . . [S]uch an elaboration on his prior [report] is appropriate" and should not be stricken. Dow Chem. Co. v. Nova Chems. Corp. (Canada), 2010 WL 2044931, at *2 (D. Del. May 20, 2010).

         Second, as Defendants do not move to strike paragraphs 16-21, which expand on paragraph 15, 1 determine that paragraph 15 is not prejudicial to Defendants even if it embodies new opinions. Thus, the first three Pennypack factors weigh against exclusion. The fourth Pennypack factor also weighs against exclusion as there has been no allegation that Plaintiff acted in bad faith. Finally, I determine that the opinions in paragraph 15 are important rebuttal evidence, and thus, the fifth Pennypack factor weighs against exclusion. Therefore, paragraph 15 will not be struck.

         Third, paragraphs 22-27 provide new rebuttal opinions from Dr. Zhou that Defendants argue he should have disclosed in his supplemental report because the information he relied upon was available at that time. (D.I. 231 at 9). As these opinions go beyond mere elaboration, they are untimely opinions under Rule 26.

         The first Pennypack factor weighs in favor of exclusion. These new opinions were first disclosed when they were filed concurrently with Plaintiffs opposition brief to Defendants' motion for summary judgment. Moreover, to the extent the opinions contradict previous deposition testimony of Dr. Zhou, the surprise to Defendants may be greater than the average untimely disclosure of expert opinion.

         However, the second Pennypack factor weighs against exclusion. In considering Defendants' motion for summary judgment of noninfringement, I did not rely on the opinions that Defendants had moved to strike.[1] (Hr'g Trans, at 99:2-7.) Therefore, there was no prejudice to Defendants in consideration of the summary judgment motions. There is enough time before trial for ...
