Microsoft and Google financials could surface at trial

However, in an order on Monday, Robart rejected that request. The public will not be able to view the documents describing patent deals or company sales during trial, Robart ruled, but testimony will be in open court.

If a witness discloses pertinent terms, rates or payments, such information will necessarily be made public, the judge wrote.

Additionally, any documents the judge relies on for his final opinion will be disclosed, Robart wrote on Monday.

Before trial began on Tuesday, Robart said in court that he wanted to take the most expansive interpretation of the public's right to know. Several outside companies besides Microsoft and Motorola, like Research in Motion Inc, have also asked him to keep secret their royalty deals.

Robart said he would consider a request to refer to those third party companies by code names, known only to the lawyers and the judge.
