Representative Matters

  • Obtained dismissal of a breach of contract action against a human resources software company in the Eastern District of Pennsylvania. The Plaintiff claimed breach of a settlement agreement through a clumsy attempt at a poison-pill clause. We carefully and clearly argued the plain language of the agreement could not support Plaintiff's theory. The Court agreed and dismissed the action. The Third Circuit Court of Appeals summarily affirmed the District Court.

  • Obtained a favorable settlement in patent infringement lawsuit on behalf of an inventor in the Eastern District of Texas after a successful result in a claim construction hearing. The team successfully argued against the defendant's attempts to force means-plus-function language into a process patent claim. The claim construction ruling made a determination of infringement much more likely, leading to the favorable settlement. Edit
  • Obtained dismissal of trademark infringement action against a manufacturing company in the Northern District of Illinois after previously defeating a motion for temporary restraining order. The Plaintiff asserted trademark infringement through metatags to direct online shopping search results. We successfully argued to the Court that the Plaintiff's allegations were based on speculation and contained no factual support. Edit
  • Following a one-week jury trial, we obtained a favorable settlement for our client during jury deliberations on a claim involving common law investor fraud. Edit
