The Sherman Act prohibits restraints of trade; Clayton Act Sec 2 targets monopolization and attempts to monopolize.
Clayton Act Sec 2 addresses price discrimination.
DOJ enforces; FTC enforces many antitrust rules alongside DOJ.
Price fixing is a classic per se illegal restraint under the Sherman Act.
Requires both market power and intentional maintenance of that power.
Identifying the relevant product and geographic market is essential to assess power.
Courts can issue injunctions and damages; treble damages may apply.
This is a classic trick. The law focuses on physical attributes, not consumer perception or branding.
This is a fundamental distinction. The Sherman Act carries criminal penalties (felonies). The Clayton Act is primarily a civil statute. While the House version wanted criminal penalties, the Senate version (which passed) removed them.
This is the core of the "Chicago School" shift. It is the most important philosophical point for an undergraduate law student to understand.
Section 4G(3) excludes proprietorships and partnerships; 4C is for "natural persons"
Section 8(a)(2)(A) provides a "Safe Harbor." Even if the corporations are large, if the competitive sales of either corporation are below the adjusted threshold ($5,440,200 for 2026), the interlock is legal.
Under 2026 rules, a filing is required if the deal is > $133.9M AND the "Size of Person" test is met ($267.8M and $26.8M). TechGiant ($1B) and StartupInc ($30M) both exceed those respective limits.
Section 4D specifically states that in parens patriae price-fixing cases, damages may be proved in the aggregate by "statistical or sampling methods" without the necessity of separately proving individual claims.
