Delaware Court of Chancery Interprets New Section 144 and Applies Heightened Presumption of Director Independence
On June 15, 2026, the Delaware Court of Chancery issued an Opinion interpreting Section 144 of the Delaware General Corporation Law (the DGCL), the landmark statutory measure adopted last year to provide safe harbors for certain conflicted transactions and address director independence, among other reforms.1 The Opinion arose in a common context in Delaware stockholder litigation: claims over director and management compensation. In the decision, Vice Chancellor Lori W. Will applied, for the first time, the statute’s heightened presumption of independence for directors of public companies determined by the board to be independent under the relevant NYSE or Nasdaq listing standards to dismiss derivative claims on demand futility grounds.

U.S. Supreme Court Addresses Liability for Patent Infringement by Generic Pharmaceuticals
In a unanimous opinion by Justice Ketanji Brown Jackson, the U.S. Supreme Court held that Amarin, the developer of Vascepa® (reference listed drug), failed to plausibly allege that Hikma actively induced infringement of Amarin’s method of use patents based on Hikma’s statements and materials related to its generic version of Vascepa®, reversing the decision by the U.S. Court of Appeals for the Federal Circuit (Federal Circuit). Although much of the import of this decision will not be fully understood until lower courts interpret this ruling, the Supreme Court provided guidance regarding one of the requirements for alleging a claim for induced patent infringement—one must plausibly allege that the defendant actively encouraged infringing use, not merely whether others could plausibly read statements by the defendant as instructions to infringe.
