Locked in a bitter legal dispute, Apple and Qualcomm are due to meet in multiple courts around the world this week. First up is a hearing Monday before the U.S. International Trade Commission, which has the power to ban products from being imported into the U.S.

Why it matters: These two giant tech companies are both used to getting their way. Apple is trying its best to get by without Qualcomm's chips, but may not be able to avoid its patents. Meanwhile, Qualcomm has lost a good chunk of business, with Apple going to Intel for modem chips.

Why it's a big deal: Because it's an interesting test for U.S. and Chinese antitrust authorities, both of which have become reluctant to approve global semiconductor mergers.
