23 Intel Corp. entered into cross license with Hewlett-Packard Company (HP) by which each party received a nonexclusive licenseto make, use, and sell any product covered by any of the licensed patents of the other party. Cyrix and ULSI, Intel competitors, thereafter contracted with HP to make for them microprocessors of their design. When Intel sued Cyrix and ULSI for infringement of Intel’s patents, they alleged their products were licensed because the products were made and sold by an authorized licensee. The courts agreed. The best explanation for courts’ decisions is:
(A) patent exhaustion
(B) patent infringement
(C) patent invalidity
(D) patent nondisclosure
