REDMOND, Wash. - A U.S. District Court judge in Los Angeles has ruled that Microsoft Corp. will have to pay Alcatel-Lucent more than $500 million for infringing on two patents.

One patent covers how software users fill out forms. The other is related to the use of a stylus on a tablet computer.

Judge Marilyn L. Huff on Thursday denied Microsoft’s request for reconsideration of a jury’s decision and the amount of damages the jury awarded Alcatel.
