Microsoft was considered the winner in a split decision in the earlier case.

Onyx Pharmaceuticals (ONXX), after rejecting several takeover attempts from Amgen (AMGN), has accepted a sweetened bid from the biotech giant. The Amgen bid is valued at $10.4 billion, or $125 a share. That's up about $5 a share from the original offer. Onyx is being sought for its pipeline of drugs to treat cancer.
