This appeal involves the question of venue in a Declaratory Judgment suit attacking the validity of a patent owned by the defendant-appellant.
The appellant, defendant below, is a Delaware corporation with its principal office at Ambler, Pennsylvania. It is licensed to do business in the State of Michigan and had appointed a registered agent in the State of Michigan to accept service of process. It has commercialized a chemical weed-killer made in accordance with Jones Patent No. 2,390,941 for Methods and Compositions for Killing Weeds. The appellee, plaintiff below, is a Michigan corporation and is engaged in the manufacture and sale of a weed-killer compound, which appellant claims to be an infringement. Under date of April 26, 1916, appellant’s counsel mailed a letter from Philadelphia, Pennsylvania, to the appellee at Midland, Michigan, giving them notice of its ownership of the Jones patent and the appellee’s infringement thereof and calling upon the appellee to cease the acts of in *958 fringement. Following an exchange of letters, the appellee on May 28, 1946 filed this action against appellant in the United States District Court for the Eastern District of Michigan seeking a declaratory judgment that Patent No. 2,390,941 was invalid, that no valid claim thereof was infringed by appellee or its customers, and that the court enjoin the appellant from annoying or intimidating the appellee or its customers and from bringing suit against the appellee or its customers by reason of said patent. The complaint alleged that an actual controversy existed between the parties concerning the validity of the patent, and that the patent was invalid for several reasons therein stated. It also alleged diversity of citizenship between the parties, that the amount of the controversy exceeded $3,000 and that the appellant was threatening appellee’s customers with infringement suits, which were unfounded but which threatened to create irreparable damage to the appellee. The appellant moved to dismiss the action on the ground that the venue was improper. On June 10, 1946, the appellant filed a civil action against the appellee in the U. S. District Court for the Southern District of New York charging infringement by the appellee of the Jones patent and praying for an injunction against further Infringement and an accounting for profits and damages. On June 22, 1946, the ap-pellee moved in the present suit that the appellant be enjoined from prosecuting the New York suit and that it file a consent to a stay of proceedings in that case. On July 11, 1946, the District Judge entered an order denying appellant’s motion to dismiss the action, and also entered a second order enjoining the appellant from prosecuting the New York action pending final disposition of this case and directing it to sign and forward to New York within two days a consent to a stay of proceedings in that case. The present appeal is from both orders.
The order overruling appellant’s motion to dismiss the action for improper venue is interlocutory and not an appeal-able order if considered alone. But this Court has jurisdiction of the appeal from the interlocutory injunction by virtue of § 227, Title 28 U.S.C.A. On such an appeal the reviewing court has the power to also review the order refusing to dismiss the complaint. Deckert v. Independence Shares Corporation,
The parties agree that a suit for declaratory judgment involving the validity and infringement of a patent is one ari^jng under the patent laws, thus conferring jurisdiction on the District Court under § 24(7) of the Judicial Code. § 41(7), Title 28 U.S.C.A. The rule appears well settled. E. W. Bliss Co. v. Cold Metal Process Company, 6 Cir.,
The Federal Declaratory Judgment Act, § 400, Title 28 U.S.C.A., is merely a procedural statute which provides an additional remedy for use in those controversies of which the district courts already have jurisdiction. Venue, as well as jurisdiction, must be found in some other statute. Appellant claims that. venue in the present case is controlled by § 48 of the Judicial Code, § 109, Title 28 U.S.C.A., which provides: “In suits brought for the infringement of letters patent the district courts of the United States shall have jurisdiction, in law or in equity, in the district of which the defendant is an inhabitant, or in any district in which the defendant * * * shall have committed acts of infringement and have a regular and established place of business.”
Section 48 is the exclusive provision controlling venue in patent infringement suits. Stonite Products Company v. Melvin Lloyd Company,
However, we agree with the appellee that the present action is not a suit “brought for the infringement of letters patent” as provided by Section 48. Although the validity of a patent is -involved, the action is not one brought by the owner of the patent, nor one brought for the infringement of the patent. On the contrary, the action is a declaratory judgment suit, specifically provided for by a separate statutory provision, and was brought to have the patent declared invalid instead of seeking damages for any infringement. The plain wording of the statute does not bring the present action within its scope. Its purpose was to protect an alleged infringer from being brought into a foreign court. General Electric Company v. Marvel Company, supra,
Under Section 51 of the Judicial Code, with certain exceptions not material here, “* * * no civil suit shall be brought in any district court against any person by any original process or proceeding in any other district than that whereof he is an inhabitant; but where the jurisdiction is founded only on the fact that the action is between citizens of different States, suit shall be brought only in the district of the residence of either the plaintiff or the defendant.” The last quoted provision permitting suit in the district of the residence of either the plaintiff or the defendant is restricted to cases where jurisdiction is founded on diversity of citizenship alone. Where jurisdiction also exists for other reasons, the provision is not applicable and the action must be brought in the district of which the defendant is an inhabitant. Macon Grocery Company v. Atlantic Coast Line,
Appellee contends that although the appellant is not an inhabitant of the Eastern District of Michigan, yet it waived venue under § 51 by registering its agent for service of process in Michigan; that although this Court held in Blaw-Knox Company v. Lederle, supra, that the venue under § 48 was not waived under the rule
*960
in the Neirbo case by such registration, yet such registration does constitute a waiver under that rule when § 51 is involved. Section 51 was the section involved in the Neirbo case. But § 51, as pointed out above, contains two separate provisions, one dealing with venue generally, and the other dealing exclusively with venue in diversity of citizenship cases. The Neirbo case was a diversity of citizenship case; the present case is not. Some of the language in the opinion in the Neirbo case might indicate the announcement of a rule applicable to all suits in the U. S. District Courts. It was so construed in Crosley Corporation v. Westinghouse Electric & Mfg. Co., supra, 3 Cir.,
The orders of the District Court granting the interlocutory injunction and denying appellant’s motion to dismiss the action are reversed, and the action is remanded to the district court for further proceedings in accordance with these rulings. This disposition of the case makes it unnecessary to pass upon appellant’s petition for a Writ of Prohibition.
