Surrendering a potentially lucrative asset to win government approval for their merger, Chevron Corp. and Unocal Corp. on Friday gave up a group of controversial Unocal gasoline-formula patents that could have driven up California gasoline costs by $500 million a year.

State officials, the FTC and Unocal's rivals had accused El Segundo-based Unocal of hoodwinking the Air Resources Board into adopting clean-air fuel specifications that dovetailed with formulas Unocal was secretly patenting.

Unocal always argued that it didn't do anything wrong and that the financial impact of its patents wasn't nearly so great.
