Syllabus

<p>1. Patents — Suit foe Infringement — Effect of Change of Ownership.</p> <p>A court of equity, which has acquired jurisdiction of a suit by the owner of a patent to enjoin its infringement and to recover damages for past infringement, does not lose such jurisdiction because, pending the suit, the patent is assigned to another, who is brought in by a supplemental bill under equity rule 57, and may proceed, not only to grant an injunction, but to award damages to both the original complainant and his assignee for infringement proved during the time of their respective ownership.</p> <p>2. Same — Infringement—Boottree.</p> <p>The Leadam patent, No. 621,423, for a boottree, was not anticipated, discloses invention, and is entitled to a fairly liberal construction; also held infringed.</p>
