IPNews® - Sony Corp.’s PlayStation 3 and at least one of its Blu-ray players infringes four of TV Interactive’s patents, according to an expert witness’s testimony in front of a San Francisco jury last Wednesday. 

TV Interactive filed a lawsuit against Sony alleging that the company’s PlayStation 3 and BDP-S500 Blu-ray disc player infringe on patents owned by TV Interactive that cover technologies that allow discs to be played automatically, rather than requiring the user to press a play button.  Sony argued against the allegations, saying that TV Interactive knew about Sony’s infringing technology since at least 1996, but chose not to do anything about it.
