Opinion

NORDBYE, Chief Judge.

This suit was commenced on July 8, 1954. Plaintiff alleged that the G. E. Mack Company, a partnership, and the individual defendants comprising that partnership, were marketing a trouser hanger known as the “Topper” hanger, which infringed plaintiff’s patent No. 2,-171,693 issued on September 5, 1939. By stipulation, Fortner & Perrin, Inc., manufacturer of the Topper hanger, was granted leave to intervene and became a party to the action. Plaintiff alleges infringement of Claims 1 and 2 of his patent, which reads:

“1. A trouser hanger including, a shank arranged at its upper end to be supportingly connected with a suitable support, a pair of arms formed of resilient material extending oppositely outwardly and somewhat upwardly from the lower portion of said shank, the free ends of said respective arms being bent into respective U-shaped elements disposed in parallel, substantially vertical planes generally normal to said arms and adapted for upward insertion of the vertical portions thereof in the ends of the cuffs of a pair of trousers.
“2. A trousers hanger constructed of resilient wire and including, a shank arranged at its upper end to be supportingly connected with a suitable support, and a pair of arms extending oppositely outwardly and somewhat upwardly from the lower portion of said shank, the free ends of said respective arms being bent into respective U-shaped cuff-engaging elements disposed in parallel, substantially vertical planes generally normal to said arms and the respective legs of each of said U-shaped elements projecting upwardly for insertion in the corresponding ends of respective cuffs of a pair of trousers.”

From September 5, 1939, the date of his patent, until December 13, 1949, a period of some ten years, plaintiff failed to promote the sale or manufacture of his hanger. On December 13, 1949, he granted an exclusive license to manufacture and market the hanger to one William H. Lynch, a resident of the State of New York. Lynch experimented with various designs made according to the Glendenning patent and made some wire hangers, but he did little, if anything, to promote the sale of the hanger. It appears that about one year after the execution of the license agreement to Lynch, the latter took on a full-time position as an automobile dealer and apparently abandoned any attempt to carry out the terms of this license agreement. At least, Glendenning never received any royalties from Lynch. The parties have stipulated that neither Glendenning nor Lynch ever sold the wire hanger depicted in plaintiff’s patent during its entire life. On October 20, 1955, plaintiff notified Lynch that the license agreement was; cancelled due to Lynch’s failure to manufacture and market the hanger. A similar notice of cancellation had been sent to Lynch on January 25, 1954, but Lynch never received this letter due to a change of address.

In 1945 one R. A. Kelsey, a resident of California, filed an application for a patent on a garment hanger. The predecessor of Fortner & Perrin, Inc., began to manufacture the allegedly infringing hanger under what they believed to' be a validly pending Kelsey patent. The patent was granted to Kelsey on May 10, 1949, as patent No. 2,470,079. There is some question as to whether or not the Topper hanger purportedly manufactured undér the Kelsey patent conforms to the specifications of that patent in that the arms of the Topper hanger as manufactured slope upward. Neither the specifications of the Kelsey patent nor the sketch accompanying it discloses upward sloping arms.

[667] Fortner & Perrin, after a somewhat indifferent beginning, were able by persistent promotion methods to successfully manufacture and sell the Topper hanger to the trade throughout the Nation.

The Glendenning patent was cited as a reference by the Patent Office when the Kelsey patent was issued. It was on January 4, 1950, that Lynch notified Fortner & Perrin that its hanger infringed the Glendenning patent. When Lynch was informed by Fortner & Perrin that it was manufacturing its hanger under the Kelsey patent, Lynch took no further action and did not notify Glendenning of his letter or Fortner & Perrin’s reply. Plaintiff was unaware of the Topper hanger until September, 1953.

Both the Glendenning and the Topper hanger are designed to hang trousers by engaging them under the cuffs and both hangers utilize the same principles in achieving the desired results; that is, a hanger which will support a pair of trousers easily and reliably, and which will tend to preclude the possibility of the trousers being disengaged from the hangers. Likewise, both hangers will tend to retain the crease in the trousers when hung.

It is recognized, of course, that the patent granted to Kelsey does not insure against infringement of prior patents, Keystone Mfg. Co. v. Adams, 1894, 151 U.S. 139, 14 S.Ct. 295, 38 L. Ed. 103, but the fact that Fortner & Perrin assumed to, and did, manufacture the Topper hanger during the entire period of the existence of the Glendenning patent is an element that becomes of some significance in determining the scope of the claims of the Glendenning patent in view of the fact that the latter patent may be characterized as a paper patent.
