NEW YORK (AP) — The Latest on federal judge's ruling against Qualcomm (all times local):

10:40 a.m.

A federal judge has ruled that Qualcomm unlawfully squeezed out rivals in the cellphone chip market and charged excessive royalties.

U.S. District Judge Lucy Koh in San Jose, California, is siding with the Federal Trade Commission in the antitrust case.

She ruled Tuesday that Qualcomm must renegotiate licensing deals with customers. The San Diego company must license its patents to rival chip makers at fair prices and can't sign exclusive supply agreements with smartphone makers like Apple that block competitors from access to that market.

Under the FTC decision affirmed by Koh, Qualcomm Inc. must submit to monitoring for the next seven years to make sure it follows the order.

Qualcomm says it will appeal.

The chipmaker's stock is down 11% in morning trading.
