Expert Opinion on Reasonable Royalty Excluded As Unreliable Because It Was Based on a Litigation Verdict and Did Not Account for Litigation-Related Economic Circumstances

In an ANDA litigation, the District of Delaware recently denied the defendants’ motion to compel the production of correspondence between the plaintiffs’ testifying expert and a third-party analyst who had performed experiments and provided data used by the testifying expert. The court found that the scope of material sought by the motion was overbroad and disproportionate to the needs of the case.

In an ANDA litigation, the District of Delaware recently denied the plaintiffs’ motion to strike portions of the defendants’ expert reports and related deposition testimony. Although the defendants’ invalidity contentions did not state the specific theories of invalidity upon which the expert opined, the court found that none of the Pennypack factors supported excluding that expert testimony.

The Western District of Texas recently vacated a preliminary injunction after the USPTO issued a non-final rejection in a reexamination proceeding of all claims of the asserted patent directed to magnetic data cables. Although not final, the rejection was based on a substantial question of validity that made vulnerable the counter-plaintiff’s likelihood of success on the merits.

A Northern District of Florida court denied a motion to disqualify plaintiffs’ outside counsel based on an alleged violation of a prosecution bar because, although the issue was “not free of doubt,” the court did not find a “clear violation” of the protective order. In reaching its decision, the court explained that disqualification is a “high bar” requiring compelling reasons and that motions to disqualify based on violating a prosecution bar, therefore, should only be granted “if the violation was clear.” Here, the court found it was unclear whether outside counsel prosecuted patents “related to” the asserted patent, in violation of the order, because the scope of “related to” was not clearly defined.
