the renewal copyright.[1] In the state action the present plaintiffs sought, inter alia, a declaratory judgment with respect to the rights of the parties in Superman. After a trial the official referee rendered an opinion as well as detailed findings of fact and conclusions of law. An interlocutory judgment was entered on April 12, 1948 and notices of appeal were filed by both parties. Settlement negotiations then ensued which resulted in a stipulation of settlement and the entry of a final consent judgment of May 21st, 1948. No appeals were taken, and no question has been raised as to the validity of the judgment. There is no doubt that the judgment of the state court is binding in this subsequent federal action. See Vernitron Corp. v. Benjamin, 440 F.2d 105, 108 (2d Cir.), cert. denied, 402 U.S. 987, 91 S.Ct. 1664, 29 L.Ed.2d 154 (1971).
It is equally clear that a consent judgment does have res judicata effect, Stuyvesant Insurance Co. v. Dean Construction Co., 254 F.Supp. 102, 110 (S.D.N.Y.1966), aff’d sub nom. Stuyvesant Ins. Co. v. Kelly, 382 F.2d 991 (2d Cir. 1967); 1B J. Moore, supra, ¶ 0.409 [5]; see United States v. Swift & Co., 286 U.S. 106, 115, 52 S.Ct. 460, 76 L.Ed. 999 (1932).
The only issue before us is whether the state judgment actually determined whether the copyright renewal rights to Superman were vested in the defendants here. While it is true that the term “renewal copyright rights” was not mentioned in the state court judgment, we are persuaded that the state court action finally determined that Detective, predecessor in interest to National, owned all rights to Superman without limitation.
The injunction in the 1948 decree, which enjoined the plaintiffs from publishing Superman, is not limited to the copyright period or what remained thereof but is perpetual. The plaintiffs were represented by counsel in the state court and there is no limiting language in the judgment which would support the present contention that renewal rights were preserved. On the contrary, a reading of the judgment and the findings inescapably leads to the conclusion that the decree settled for once and for all that the defendants had all right and title to Superman for all time.
Appellants argue that the agreements did not convey the renewal rights because, as a rule, a general transfer of an original copyright without mention of renewal rights does not convey the latter without proof of a contrary intention. Edward B. Marks Music Corp. v. Charles K. Harris Music Publishing Co., 255 F.2d 518, 521 (2d Cir.), cert. denied, 358 U.S. 831, 79 S.Ct. 51, 3 L.Ed.2d 69 (1958). The ready answer to this argument is that the state court action determined that the agreements conveyed all of the plaintiffs’ rights in Superman to the defendants and not just the original copyright term. Under the doctrine of res judicata we are not free collaterally to re-examine the agreements to determine whether or not the construction placed upon them was warranted. Restatement of Judgments § 48, comment a; 1B Moore, supra, ¶ 0.405 [1], at 629.
We also should point out that in Venus Music Corp. v. Mills Music, Inc., 261 F.2d 577 (2d Cir. 1958) this court held that general words of assignment can include renewal rights if the parties had so intended. Accord, cases cited in Annot., 2 A.L.R.3d 1403, 1415–16 (1965). That intent is to be determined by the trier of the facts. Here the March 1938 agreement between the parties did not simply purport to convey a copyright; in fact, the term is not mentioned in that agreement. Rather, the sale of the Superman strip conveyed the “exclusive
- ↑ The parties on this appeal have used the terms “res judicata” and “collateral estoppel” interchangeably. The distinction depends upon whether or not the former judgment was rendered on the same cause of action (res judicata) or on a different cause of action (collateral estoppel). 1B J, Moore, Federal Practice ¶ 0.441 [2] (2d ed. 1974); Restatement of Judgments § 68, comment a (1942). Since we hold that the state judgment action determined that the defendants owned all of the rights to the Superman strip without reservation, the doctrine of res judicata is properly applicable.
