What did Texas Instruments v. Hyundai Electronics Industries say about tying and patent misuse?

• A. No per se patent misuse defense here.
• B. There is per se patent misuse due to tying.
• C. Patent misuse exists only with antitrust violations.
• D. Misuse defenses require proof of market power.

Answer: (A)

Patent misuse isn't triggered by tying alone. In Texas Instruments v. Hyundai Electronics Industries, the court explained that tying a patented item to a second product does not automatically constitute patent misuse on a per se basis. Patent misuse requires showing that the patentee used the patent to obtain rights beyond what the patent grants or to restrain the use of the invention in a way that extends the patent monopoly. The tying arrangement in this case did not, by itself, cross that line, so it did not create a per se patent misuse defense. In practice, you assess misuse by looking at whether the licensing terms extend beyond the patent’s lawful scope or improperly restrain use, not merely by the presence of a tie.
