Opinion

FINDINGS OF FACT AND CONCLUSIONS OF LAW

LYNCH, District Judge.

I. FINDINGS OF FACT

The Parties and Jurisdiction

1. This is a patent infringement action filed April 8, 1964, seeking an injunction and damages for infringement of three patents, all of which are directed to the provision of a slot in a flange of admittedly old bobbins or winding forms for accommodating the beginning or lead-in wire of the winding on such bobbins or winding forms. Defendant contends that the three patents in suit are invalid but, if valid, Defendant admits *216 that the single form of slot used in the bobbins which it manufactures renders these bobbins an infringement (or contributory infringement) of all three patents.

2. Plaintiff, Amerline Corporation (hereinafter referred to as “Amerline”), formerly American Molded Products Company, was a corporation of the State of Illinois having its principal place of business in Chicago, Illinois. After commencement of this action, it assigned all its assets and liabilities to C-R Plastics Corporation, an Illinois corporation which, by change of name, became Amer-line Corporation and also has its principal place of business in Chicago, Illinois. The latter Amerline Corporation has been substituted for the former Amerline Corporation as one of the Plaintiffs.

3. Plaintiff, Minneapolis-Honeywell Regulator Company (hereinafter referred to as “Honeywell”), is now, by change of name, Honeywell Inc., and is a corporation of the State of Delaware, having its principal place of business in Minneapolis, Minnesota.

4. Defendant, Cosmo Plastics Company (hereinafter referred to as “Cos-mo”), is a partnership having its principal place of business in Cleveland, Ohio.

5. The Court has jurisdiction of the parties and the subject matter [Amended Complaint and Answer].

6. In addition to the instant litigation which initially included Magnecraft Electric Company as a Defendant, Plaintiffs, on April 8, 1964, filed two additional suits in this District agáinst customers of Defendant, all involving the same three patents: Civil Action No. 64 C 618, Amerline Corporation and Minneapolis-Honeywell Regulator Company v. Electro Counter & Motor Co.; Civil Action No. 64 C 619, Amerline Corporation and Minneapolis-Honeywell Regulator Company v. Comar Electric Co. On November 30, 1964, the Complaint in the instant suit was dismissed without prejudice as to Defendant’s customer, Magnecraft Electric Company, and on November 30, 1964, the suits against the other two customers of Defendant, Civil Actions Nos. 64 C 618 and 64 C 619, were dismissed without prejudice.

Ownership of Patents and the Right to Sue

7. Patent No. 3,083,930 (PX 1A), assigned to Honeywell, issued in the name of Byron 0. Brekke April 2, 1963, on an application filed August 13, 1959, and is entitled “Winding Form”. Patent No. 3,117,294 (PX 3A), assigned to Amerline, issued in the names of Peter C. Muszynski and Arthur G. Weyrich January 7, 1964, on an application filed September 8, 1959, and is entitled “Bobbin with Insulated Lead-In Means”. Patent No. 3,131,371 (PX 2A), assigned to Honeywell, issued in the names of Byron O. Brekke and Roy C. Johnston April 28, 1964, on an application filed March 9, 1959, and is entitled “Winding Form Having Means for Protecting Electrical Coil Leads” [PX 1A, 2A, 3A].

8. Amerline has an exclusive license under both Honeywell patents, under which license Amerline pays a royalty on its production to Honeywell; and Honeywell has a free, non-exclusive license under the Amerline patent. Amerline has the right to sue under all three patents in suit.

Disclosures of the Patents in Suit

9. All three patents in suit and the claims thereof are primarily concerned with the provision of a slot in the flange of a winding form or bobbin adapted to be molded from plastic materials having insulating properties and comprising a hollow core or tube, on which an electrical coil is wound, and flanges at each end of the tube and, in some cases, intermediate the ends of the tube,, to define one or more winding zones or spaces in which the turns of a single coil or a plurality of coils may be confined and retained in place during and after the winding operation. Such winding forms are commonly termed “bobbins”.

10. The Brekke patent discloses bobbins having either of two slot forms, one (Figs. 1-5) being a diagonal slot running completely through the flange from the winding zone to the outer surface of the *217 flange and from the tube of the bobbin to the peripheral edge of the flange, and the other (Fig. 6) running diagonally into the flange from the winding zone and extending from the tube through the peripheral edge of the flange, but not passing through the outer surface of the flange so that the outer surface is “continuous”. This patent also discloses a terminal lug mounted on each slotted flange adjacent the slot therein for connection too a lead wire emerging from the slot. Plaintiffs characterized this patent as directed to a diagonal slot extending all the way through the bobbin flange.

11. The Brekke et al. and Muszynski et al. patents disclose substantially identical bobbins having substantially identical slots, and the bobbins of both of these patents have terminal lugs mounted on each slotted flange and substantially identically located in the two patents relative to the flange slots. In both of these patents, the flange slots include a portion which extends into the flange from the winding space along the inner surface of the flange from the bobbin tube out to the peripheral edge of the flange. This slot portion is intersected at right angles by a second slot portion which extends parallel to the flange between the inner and outer surfaces thereof, without penetrating through the outer flange surface, so that the slots appear L-shaped when viewing their configurations where they open out through the peripheral edges of the flanges. Plaintiffs inaccurately characterized the Brekke et al. patent as directed to a diagonal slot which does not extend all the way through the bobbin flange (no such slot form being disclosed therein) and the Muszynski et al. patent as directed to an L-shaped slot in the bobbin flange.

The Patent Claims in Suit

12. The specific claims in suit are claims 4 and 5 of Brekke patent No. 3,083,930, claims 1-4 (all claims) of Muszynski et al. patent No. 3,117,294, and claims 1, 2 and 3 (all claims) of Brekke et al. patent No. 3,131,371.

13. The broadest of the claims in suit are claims 4 and 5 of the Brekke patent. These claims read on bobbins having a flange that is slotted in either of the two diagonal slot forms disclosed in this patent, i.e., whether or not running completely through the flange from the winding zone to the outer surface of the flange. These claims are broad énough to read also on bobbins having the L-shaped slots disclosed in both of the other two patents in suit and present in all of the accused bobbins of Defendant.

14. The next broadest claims are the three claims of the Brekke et al. patent. These claims read on bobbins having the diagonal slot not passing completely through the flange (Fig. 6 of the Brekke patent), and also on bobbins having the L-shaped slot.
