¶11. Patents — Action for Infringement — Persons Entitled to Site.
¶2In Rev. St. § 4919 [TJ. S. Comp. St. 1901, p. 3394], which provides that “damages for the infringement of any patent may be recovered by action on the case in the name of the party interested, either as patentee, assignee or grantee,” the. word “assignee” is used in a limited sense, as meaning an assignee of patent rights, and does not cover a mere assignee of a claim for infringement; and that section having designated the persons who may sue for infringement the right cannot be extended to another by a state statute.
¶3At Law. Action for infringement of patent. On demurrer to declaration.
¶4Maynadier & Rockwell, for plaintiff.
¶5John C. Edwards and Nathan Heard, for defendants.
¶7From the declaration it appears that after the expiration of letters patent No. 260,063 the patentee, Streat, assigned to the plaintiff all his claims for infringement by the defendants. The plaintiff sues in his own name, alleging infringement by the defendants during a period within the life of the patent.
¶8The first ground of demurrer is “that it does not appear from said declaration that the plaintiff has any such title to or interest in the letters patent • … as entitled him to bring this action, and for that it does not from said declaration appear that the plaintiff has any right, title, or interest in the said letters patent which entitled him to bring this action in his own name.”
¶9Section 4919 of the Revised Statutes of the United States [U. S. Comp. St. 1901, p. 3394] provides: “Damages for the infringement of any patent may be recovered by action on the case, in the name of the party interested, either as patentee, assignee, or grantee,” etc.
¶10• The plaintiff relies upon section 914 of the Revised Statutes of the United States [U. S. Comp. St. 1901, p. 684], and also upon section 4, c. 173, of the Revised Laws of Massachusetts, as follows: “The assignee of a nonnegotiable legal chose in action which has been assigned in writing may maintain an action thereon in his own name, but subject to all defenses and rights of counterclaim, recoupment or set-off to which the defendant would have been entitled had the case been brought in the name of the assignee.” But this provision of the Massachusetts statutes, if applied to this action, would be inconsistent With the express provisions of section 4919, in which the word “assignee” is' used in a limited sense to indicate an assignee of patent rights, and does not cover a mere assignee of a nonnegotiable legal chose in action. Waterman v. Mackenzie, 138 U. S. 255, 11 Sup. Ct. 334, 34 L. Ed. 923; Moore v. Marsh, 7 Wall. 515, 19 L. Ed. 37; Gayler v. Wilder, 10 How. 477, 13 L. Ed. 504; Hayward v. Andrews (C. C.) 12 Fed. 786; Robinson on Patents, vol. 3, p. 122, § 937.
¶11Whenever Congress has legislated upon any matter of practice, and *573has prescribed a definite rule for the government of its courts, it is to that extent exclusive of the Legislature of the state upon the same matter. Allnut v. Lancaster (C. C.) 76 Fed. 131. As the plaintiff in this case is neither a patentee, an assignee of patent rights, nor a grantee, he is not within the provisions of section 4919, which is the only statutory authority applicable.
¶12As this ground of demurrer is decisive, it is unnecessary to consider other grounds. Demurrer sustained.
