Narrative Opinion Summary
This case involves Medeva Pharma Ltd.'s lawsuit against American Home Products, Inc. and its subsidiary, American Cyanamid Company, alleging infringement of U.S. Patent No. 6,048,700. The patent, crucial for the production of a pertussis vaccine, was issued on April 21, 2000, and the suit was filed the following day under U.S. patent laws. Medeva sought to file a First Supplemental Complaint to address ongoing infringement, which the defendants did not oppose, effectively waiving their right to respond. The court, exercising discretion under Federal Rule of Civil Procedure 15, granted the motion, emphasizing that it would not cause undue prejudice or delay. The defendants' original answer remains applicable to the new complaint. Additionally, a declaratory judgment action filed by the defendants in New York was dismissed, prompting the withdrawal of their motion to dismiss this Delaware case. The court’s decision adhered to principles ensuring a fair opportunity for Medeva to substantiate its claims, as there was no indication of bad faith or dilatory motives.
