The U.S. Supreme Court on Monday <A HREF="http://news.zdnet.com/2100-9595_22-5991952.html?tag=zdnn.alert">rejected an appeal</A> by digital media manufacturers who were battling a patent infringement lawsuit filed by flash data storage card maker SanDisk. The court denied manufacturers a petition--filed by Ritek, Memorex and Pretec Electronics--to reverse July's federal appeals court ruling that reinstated SanDisk's infringement suit. The appeals court overturned a decision by a federal judge in California, who had granted motions to dismiss the case at different times in 2003 and 2004. At issue are flash memory devices used in products such as digital cameras, personal digital assistants and MP3 players.
