113 F. 285 | 7th Cir. | 1902
after stating the facts, delivered the opinion of the court.
The only question presented is whether Dooley is a necessary party to the suit. This question in turn depends upon the further question whether the contract constituted an assignment by Dooley of his title to the patent, or was merely an exclusive license. An assignment or grant conveys (i) the whole patent, comprising the exclusive right to make, use, and vend the invention throughout the United States; or (2) an undivided part or share of that exclusive right; or (3) the exclusive right under the patent within and throughout a specified part of the United States. “A transfer of either of these three kinds of interest is an assignment, properly speaking, and vests in the assignee a title in so much of the patent itself, with a right to sue infringers; in the second case, jointly with the assignor; in the first and third cases, in the name of the assignee alone. Any assignment or transfer short cf one of these is a mere license, giving the licensee no title in the patent, and no right to sue at law in his own name for infringement.” Waterman v. McKenzie, 138 U. S. 252, 255, 11 Sup. Ct. 334, 34 L. Ed. 923. See, also, Gayler v. Wilder, 10 How. 477, 13 L. Ed. 504; Pope Mfg. Co. v. Gormully & Jeffery Mfg. Co., 144 U. S. 248, 249, 12 Sup. Ct. 641, 36 L. Ed. 419. In the construction of this instrument, seeking to ascertain the intention of the parties to it, we must be governed by the familiar canons of interpretation. We must gather that intention from within the four corners of the instrument, giving to the language employed its usual signification, and, if possible, reconcile discrepancies and avoid repugnancy, having regard also to the ancient rule that general words in one clause may be restricted by the particular words in a subsequent clause. The preamble of the contract recites that Dooley has invented certain improvements, and .contemplates making still others in the particular mechanism stated, and that the company is desirous of acquiring “the exclusive right to make, use, and sell to others to be used and sold” planters embodying the patented improvements and those as yet unpatented; and thereupon Dooley conveys to the company, “its assigns and legal representatives, the exclusive right to manufacture, use, and sell, and to- sell to others to be used and sold, said improvements as patented, which are made, but not patented, and other improvements which may be made and patented, by said party of the first part, throughout the United States and territories thereof, to the full extent of the term for which said patents are or may be granted, on the conditions hereinafter named, at its factory in Moline, Illinois, or at such other place or places as it may elect.” There is here no obscurity, ambiguity, or defect
The decree is reversed, and the cause is remanded, with direction to the court below to overrule the demurrer.
