Defendant, in its brief on appeal, argues that, if the patent is invalid, the agreement is void as in restraint of trade, and that therefore we must inquire into the validity of the patent. This contention was not made in the court below; but we do not reject it on that account, since Muncie Gear Co. v. Outboard Co.,
In Sola Electric Co. v. Jefferson Electric Co.,
In the instant case, too, the covenant is express. But here we find it in an agreement, containing no price-fixing clause, which was made by one not a licensee or assignor. That the defendant is not a licensee or assignor may strengthen its defensive position, for reasons we shall note later. It is suggested, however, that the Sola doctrine is inapplicable to an agreement which unreasonably restrains competition but does not fix prices. We cannot agree. True, the court in the Sola case [
The agreement here is one by which defendant agreed with plaintiff, a competitor, to cease making and selling, throughout the United States and for thirteen years, a commodity which both parties had theretofore been making and selling. If, disregarding the patent, the effect of the agreement would be unreasonably to restrain competition, 1b then only the validity of the patent can rescue the agreement from the jaws of the anti-trust laws. Accordingly defendant’s covenant acknowledging the patent’s validity constitutes, in effect, an undertaking that, if sued by plaintiff for enforcement of that agreement, defendant will not assert the defense that the agreement is illegal. Such a raising-by-one’s-boot’s-straps undertaking, of course, cannot be enforced. 2
In the Sola case, the court said that, in its earlier decisions concerning the estoppel of a patent licensee to contest the .patent’s validity, the rule of estoppel ha«d been applied without discussion, and suggested that, absent a Sherman Act situation, the question may be one of state law. 3 This would seem to mean that such ar^ *785 agreement as that before us is illegal, unless the patent is valid, if, regarding the agreement as one relating to an unpatented commodity, it would be illegal according to State law. By the common law of most jurisdictions, an agreement restricting competition is illegal unless it is “ancillary” to the sale of a business or the like. 3a In the instant case, the agreement is not thus “ancillary.” Accordingly, even if it does not violate the Sherman Act, it may, under the Sola doctrine, be unenforceable, unless the patent is valid.
The agreement here perhaps confronts another difficulty. In most of the cases, decided before Sola, which sustained an estoppel, whether implied or based on an express covenant, the estoppel ran against either an assignor of the patent or a licensee thereunder, and those decisions seemed to have relied on analogies of conveyances or leases of land. 4 But as here the defendant is neither an assignor nor a licensee, the patent-estoppel cases, even as they stood in pre-Sola days, may not be protective of the agreement, and, even assuming- that the Sola doctrine is limited to price-fixing agreements, the agreement here may be illegal under the common-law rule as to contracts, not “ancillary,” in restraint of trade.
In Pope Mfg. Co. v. Gormully,
In United Lens Corp. v. Doray Lamp Co., 7 Cir.,
On one theory or another, it may be that the agreement here cannot bar an inquiry into the validity of the patent. Yet, as this issue was not raised in the trial court, there was no adequate opportunity to present evidence as to whether (a) the agreement does or does not violate the antitrust laws and is legal under State law; or (b) the facts are such that, if violative of neither the anti-trust laws nor any other federal law nor the State law, the agreement does or does not come within the doctrine of the Pope Mfg. case; or (c) if plaintiff fails as to (a) and (b), the patent is or is not valid; or (d) if the patent is invalid and if the agreement is not illegal but comes within the Pope Mfg. Co. doctrine, still plaintiff is entitled to damages at law. Accordingly, we shall not now pass on the question of the patent’s validity or that of recovery on the contract, but, “to the end that injustice may not be done,” we shall now remand the case to the trial court with directions to vacate the decree and to hear evidence of the kind we have just described. 12
The case, however, has been fully heard, here and below, on the issue of infringement and breach of agreement, and it will save time if we now decide that issue, assuming for the moment that the patent is valid or, if not, that the agreement is not illegal. The trial court correctly held for plaintiff on that issue of infringement. So crowded is this field that, in the light of the prior art now appearing in the record, the claims must be markedly narrowed, for they disclose a combination, at best not startlingly ingenious, of elements by no means novel in the art. (For that reason, our decision as to the scope of the claims can be of little interest to anyone except the parties to the suit, and we need not enlarge on the details of the claims or those of defendant’s device.) However, no matter how narrowly the claims are construed, the defendant may not avoid infringement and breach of its agreement by an absurdly literal interpretation of words which, in ordinary usage, have a broad meaning. Consequently “cord loops” must be interpreted to include wire loops, since “cord” ordinarily includes wire as we speak of “picture cord”. Moreover, while, with respect to such a patent as this, the doctrine of equivalence must be most cautiously employed, it is not, even here, so completely without efficacy that defendant can, as it has tried to do, escape infringement and the obligations of its agreement, by adopting contrivances, which any mechanic skilled in the art would recognize at a glance to be obvious substitutes for those disclosed in the claims. Defendant’s wires are straight throughout the major portion of their length and are therefore “substantially straight.” In the patent, the cords or cord loops pass through the “eyes” of the wires, while, in the defendant’s device, “hog rings” pass through the “eyes.” These differentiated means used by the defendant are of a kind well-known in the art to be almost the precise equivalent of those in the patent. Defendant plainly infringed and violated its agreement (which, for the purposes of this discussion and for the time being, we assume to be valid).
There was no error in the refusal of the trial court to compel plaintiff to elect as between its two causes of action. The *788 two were not inconsistent. The elements of damage for breach of the contract (if valid) and for infringement of, the patent (if valid) may well be different; to the extent that they may overlap, the trial court’s order was fully protective of defendant.
Reversed and remanded, with directions in accordance with the foregoing opinion.
Notes
Also pertinent are eases holding that a court should sua sponte raise the question of the illegality of an agreement where the illegality is serious (especially where an important public interest is involved), and that the defense of illegality cannot ordinarily be waived. See, e. g., Oscanyan v. Winchester Repeating Arms Co.,
See, also, B. B. Chemical Co. v. Ellis,
In United States v. Socony Vacuum Oil Co.,

See the opinion of the Circuit Court in that case, C.C.N.D.Ill.,
The Circuit Court had indicated that there may have been overreaching by the plaintiff in inducing the defendant to sign the agreement, but concluded its opinion with the statement that “it ought not to be enforced in a court of equity, even if tiie defendant fully understood and comprehended the force and import of every paragraph of it.”
The Supreme Court, referring to the evidence as over-reaching, said (144 U.S. at pages 237, 238,
On the same day the court, in infringement suits brought under several of the patents included in the agreement but under which defendant was not licensed, held some of those patents invalid. See
On this point, the court said, in part (pages 234, 235 of 144 U.S., page 636 of
There is -the additional fact that the agreement provided that plaintiff might, on defendant’s breach, sue out an injunction against him without notice. But, while the court adverted to that provision as unfair, it did not ground its decision on that unfairness, probably because defendant had been given notice of plaintiff’s injunction suit.
In that case the agreement not to contest validity covered both the patent in suit and other patents under which defendant was not licensed. The defendant was licensed under the patent in suit but only as to cex-tain machines; the court held that, although the agreement could not be enforced as to the other patents, it would be enforced as to the patent in suit even as to machines not included in the license.
The parties to the agreement called it a “license,” but, as the court noted, in fact it was not; for the defendant, in consideration of licenses under another patent, agreed not to contest the validity of, and not to infringe, the patent in suit, under which defendant was granted no license.
That case was decided before the Seventh Circuit was reversed in the Sola case, and the court made no reference to the anti-trust laws.
The court, in the Pope Mfg. case, left open the possibility of recovery of damages at law for the breach of the agreement.
