Google has just been ordered to pay $5M for infringing patent 5,893,120 (hereafter "Patent 120"). This patent covers a very simple data structure and the algorithms for manipulating it.

On Tuesday Yahoo and its lawyers from McDermott Will & Emery won a jury verdict that Yahoo does not infringe Bedrock's patent, which involves code for removing expired records while the operating system performs other operations. On April 15, a separate Tyler jury reached a contrary conclusion in Bedrock's case against Google, finding that Google infringed the same patent and awarding Bedrock $5 million in damages. ... Yahoo's four co-defendants all settled the weekend before the trial started; the docket indicates that both Amazon and SoftLayer agreed to licensing deals as well as confidential settlements.
