Standard Oil Co. v. United States (1911)

Another landmark among the Court Cases That Changed Business Law is Standard Oil Co. v. United States. At the time, Standard Oil controlled a massive share of the oil industry in the United States.

The government accused the company of monopolistic practices that violated the Sherman Antitrust Act. The Supreme Court ruled that Standard Oil must be broken into several smaller companies to restore competition in the market.

This case became a cornerstone of antitrust law and set a precedent for regulating monopolies. It demonstrated that governments can intervene when companies gain excessive control over an industry.
