In US Philips Corp. v. International Trade Commission, is patent tying per se unlawful?

• A. No, patent to patent tying is not unlawful per se.
• B. Yes, tying is per se unlawful.
• C. Only if essential patents are included.
• D. Only if licensee cannot license essential patents separately.

Answer: (A)

The main idea here is that tying arrangements involving patents aren’t automatically illegal. In US Philips Corp. v. International Trade Commission, the Supreme Court rejected treating patent-to-patent tying as a per se violation. Instead, such ties are evaluated under the rule of reason. This means you weigh procompetitive justifications—like encouraging efficient licensing of a portfolio of patents, reducing transactions costs, and avoiding royalty stacking—against any anti-competitive effects, such as foreclosing licensors or keeping rivals out of the market. Because a patent tying arrangement can sometimes promote innovation and licensing efficiency, it isn’t automatically unlawful simply because two patents are tied together. Only if the tying arrangement demonstrably harms competition on balance would it raise antitrust concern under the rule of reason.
