delivered the opinion of the Court.
The United States brought this civil action to prevent and restrain violations of the Sherman Act1 by appellant, *595Timken Roller Bearing Co., an Ohio corporation. The complaint charged that appellant, in violation of §§ 1 and 3 of the Act,2 combined, conspired and acted with British Timken, Ltd. (British Timken), and Societe Anonyme Frangaise Timken (French Timken) to restrain interstate and foreign commerce by eliminating competition in the manufacture and sale of antifriction bearings in the markets of the world. After a trial of more than a month the District Court made detailed findings of fact which may be summarized as follows:
As early as 1909 appellant and British Timken’s predecessor had made comprehensive agreements providing for a territorial division of the world markets for antifriction bearings. These arrangements were somewhat modified and extended in 1920, 1924 and 1925. Again in 1927 the agreements were substantially renewed in connection with a transaction by which appellant and one Dewar, an English businessman, cooperated in purchasing all the stock of British Timken. Later some British Timken stock was sold to the public with the result that appellant now holds about 30% of the outstanding shares while Dewar owns about 24%.3 In 1928 appellant and Dewar organized French Timken and since that date have together owned all the stock in the French company. Beginning in that year, appellant, British Timken and French Timken have continuously kept operative “business agreements” regulating the manufacture and sale of antifriction bearings by the three companies and providing for the use by the British and French corporations of the trademark “Timken.”4 Under these agreements *596the contracting parties have (1) allocated trade territories among themselves; (2) fixed prices on products of one sold in the territory of the others; (3) cooperated to protect each other’s markets and to eliminate outside competition; and (4) participated in cartels to restrict imports to, and exports from, the United States.
On these findings, the District Court concluded that appellant had violated the Sherman Act as charged, and entered a comprehensive decree designed to bar future violations. 83 F. Supp. 284. The case is before us on appellant’s direct appeal under 15 U. S. C. § 29.
Although appellant has indiscriminately challenged the District Court’s judgment and decree in over 200 separate assignments of error, the real grounds relied on for reversal are only a few in number.5 In the first place, appellant contends that most of the District Court’s material findings of fact are without evidential support, that they “ignore or fail properly to evaluate” evidence supporting appellant’s position, and that it was error for the court to refuse to make additional findings. For the most part, this shotgun approach is actually only a dispute as to the proper inferences to be drawn from the evidence in the record; 6 in effect, it is an invitation for *597us to try the case de novo. This Court must decline such an invitation just as it does when the Government makes the same request. United States v. Yellow Cab Co., 338 U. S. 338. In the present case, the trial judge after a patient hearing carefully analyzed the evidence in an opinion prepared with obvious care.7 Appellant’s lengthy brief has failed to establish that there was error in making any crucial, or even important, ultimate or subsidiary finding. Since we cannot say the findings are “clearly erroneous,” we accept them. Fed. Rules Civ. Proc., 52 (a).
Appellant next contends that the restraints of trade so clearly revealed by the District Court’s findings can be justified as “reasonable,” and therefore not in violation of the Sherman Act, because they are “ancillary” to allegedly “legal main transactions,” namely, (1) a “joint venture” between appellant and Dewar, and (2) an exercise of appellant’s right to license the trademark “Timken.”
We cannot accept the “joint venture” contention. That the trade restraints were merely incidental to an otherwise legitimate “joint venture” is, to say the least, doubtful. The District Court found that the dominant purpose of the restrictive agreements into which appellant, British Timken and French Timken entered was to avoid all competition either among themselves or with *598others. Regardless of this, however, appellant’s argument must be rejected. Our prior decisions plainly establish that agreements providing for an aggregation of trade restraints such as those existing in this case are illegal under the Act. Kiefer-Stewart Co. v. Seagram & Sons, 340 U. S. 211, 213; United States v. Socony-Vacuum Oil Co., 310 U. S. 150, 223-224 and note 59; United States v. National Lead Co., 63 F. Supp. 513, affirmed, 332 U. S. 319; United States v. American Tobacco Co., 221 U. S. 106, 180—184; Associated Press v. United States, 326 U. S. 1, 15. See also United States v. Aluminum Co. of America, 148 F. 2d 416, 439-445. The fact that there is common ownership or control of the contracting corporations does not liberate them from the impact of the antitrust laws. E. g., Keifer-Stewart Co. v. Seagram & Sons, supra at 215. Nor do we find any support in reason or authority for the proposition that agreements between legally separate persons and companies to suppress competition among themselves and others can be justified by labeling the project a “joint venture.” Perhaps every agreement and combination to restrain trade could be so labeled.
Nor can the restraints of trade be justified as reasonable steps taken to implement a valid trademark licensing system, even if we assume with appellant that it is the owner of the trademark “Timken” in the trade areas allocated to the British and French corporations. Appellant’s premise that the trade restraints are only incidental to the trademark contracts is refuted by the District Court’s finding that the “trade mark provisions [in the agreements] were subsidiary and secondary to the central purpose of allocating trade territories.” Furthermore, while a trademark merely affords protection to a name, the agreements in the present case went far beyond protection of the name “Timken” and provided for control of the manufacture and sale of antifriction bearings *599whether carrying the mark or not. A trademark cannot be legally used as a device for Sherman Act violation. Indeed, the Trade Mark Act of 1946 itself penalizes use of a mark “to violate the antitrust laws of the United States.”8
We also reject the suggestion that the Sherman Act should not be enforced in this case because what appellant has done is reasonable in view of current foreign trade conditions. The argument in this regard seems to be that tariffs, quota restrictions and the like are now such that the export and import of antifriction bearings can no longer be expected as a practical matter; that appellant cannot successfully sell its American-made goods abroad; and that the only way it can profit from business in England, France and other countries is through the ownership of stock in companies organized and manufacturing there. This position ignores the fact that the provisions in the Sherman Act against restraints of foreign trade are based on the assumption, and reflect the policy, that export and import trade in commodities is both possible and desirable. Those provisions of the Act are wholly inconsistent with appellant’s argument that American business must be left free to participate in international cartels, that free foreign commerce in goods must be sacrificed in order to foster export of American dollars for investment in foreign factories which sell abroad. Acceptance of appellant’s view would make the Sherman Act a dead letter insofar as it prohibits contracts and conspiracies in restraint of foreign trade. If such a drastic change is to be made in the statute, Congress is the one to do it.
*600Finally, appellant attacks the District Court’s decree as being too broad in scope. The decree enjoins continuation or repetition of the conduct found illegal. This is clearly correct. Ethyl Gasoline Corp. v. United States, 309 U. S. 436, 461. It also contains certain other restraining provisions which were within the court’s discretion because “relief, to be effective, must go beyond the narrow limits of the proven violation.” United States v. United States Gypsum, Co., 340 U. S. 76, 90. The most vigorous objection, however, is made to those portions of the decree relating to divestiture of appellant’s stockholdings and other financial interests in British and French Timken.
Mr. Justice Douglas, Mr. Justice Minton and I believe that the decree properly ordered divestiture. Our views on this point are as follows: Appellant’s interests in the British and French companies were obtained as part of a plan to promote the illegal trade restraints. If not severed, the intercompany relationships will provide in the future, as they have in the past, the temptation and means to engage in the prohibited conduct. These considerations alone should be enough to support the divestiture order. United States v. Paramount Pictures, Inc., 334 U. S. 131, 152-153; United States v. National Lead Co., 332 U. S. 319, 363. But there are other considerations as well. The decree should not be overturned unless we can say that the District Court abused its discretion. Absent divestiture, it is difficult to see where other parts of the decree forbidding trade restraints would add much to what the Sherman Act by itself already prohibits.9 And obviously the most effec*601tive way to suppress further Sherman Act violations is to end the intercorporate relationship which has been the core of the conspiracy. For these reasons, Mr. Justice Douglas, Mr. Justice Minton and I cannot say that the District Court abused its discretion in ordering divestiture.10
Nevertheless, a majority of this Court, for reasons set forth in other opinions filed in this case, believe that divestiture should not have been ordered by the District Court. Therefore, it becomes necessary to strike from the decree §§ VIII, IYB, and the phrase “or B” in § IYC. As so modified, the judgment of the District Court is affirmed.
It is so ordered.
Mr. Justice Burton and Mr. Justice Clark took no part in the consideration or decision of this case.26 Stat. 209,15 U. S. C. §§ 1-4.
These sections declare illegal all contracts, combinations or conspiracies in restraint of trade or commerce among the states and territories or with foreign nations.
Dewar died while the appeal in this case was pending. See note 10, infra.
The most recent of these agreements, which was to have governed the conduct of the parties until 1965, is dated November 28, 1938.
Appellant originally attacked the decision below in 206 assignments of error, including 69 alleged errors in the District Court’s findings of fact, 26 in its conclusions of law, and 62 based on the court’s refusal to make new and additional findings. (Later appellant abandoned 5 of the assignments.) These assignments are unduly repetitious, some are frivolous, and the excessive number obscures the actual grounds on which appellant relies for reversal. As the Government pointed out in its motion to dismiss the appeal, our prior cases justify dismissal in such situations. See Local 167 v. United States, 291 U. S. 293, 296; Phillips & Colby Construction Co. v. Seymour, 91 U. S. 646, 648. We do not take that action, however, since appellant in its brief opposing the Government’s motion has sufficiently spelled out the few real objections it raises here.
This is well illustrated by the following portion of the “Summary of Argument” which appears in the appellant’s brief: “The evidence *597relied upon by the district court as demonstrating conduct of an intentional restraint of trade by the three Timken companies from 1928 on is just as reconcilable with the conduct of a legal joint adventure as with the conduct of a combination for the purpose of suppressing competition and controlling world trade in tapered roller bearings, and therefore the district court’s decision to the contrary is clearly erroneous.” Brief for Appellant, pp. 78-79.
Appellant claims the District Court’s findings of fact and conclusions of law failed to comply with Rule 52 (a) of the Federal Rules of Civil Procedure. We think that the opinion below meets all the requirements of the Rule.
60 Stat. 427, 439, §33 (b) (7), 15 U. S. C. §§ 1051, 1115 (b) (7). The reason for the penalty provision was that “trade-marks have been misused. . . . have been used in connection with cartel agreements.” 92 Cong. Rec. 7872.
We would reject the argument that divestiture is unwise in light of current foreign trade conditions for substantially the same reasons we rejected it in connection with appellant’s contention that there was no violation of the Sherman Act.
Dewar died while this appeal was pending. Were it not for the present litigation, appellant, under the contracts between it and Dewar, would be entitled to purchase Dewar’s interest in British Timken (which would give appellant a 54% stock interest in that corporation); appellant also has a right of first refusal as to Dewar’s 50% stock interest in French Timken (which, if exercised, would give appellant 100% ownership of that company). Appellant moved in the District Court to reopen the record to admit evidence of these changed circumstances caused by Dewar’s death and for a reconsideration of the divestiture provisions of the decree. The District Court denied the motion. Mr. Justice Douglas, Mr. Justice Minton and I would hold that this ruling was within its discretion.
