Syllabus

<p>Patents—Suit fob infringement—Supplemental Bill Covering New Infringements.</p> <p>Where the defendant, pending a suit for infringement of a patent, begins the use of another alleged infringing device, separate and distinct from that complained of in the bill, although such fact does not render the suit defective, within the meaning of equity rule 57, but constitutes ground for an independent suit, the court may nevertheless, in the interest of saving delay and expense by the needless duplication of proofs, permit the question of the second infringement to be brought into the case by á supplemental bill.</p>
