MIPS (MIPS +6.7%) rallies after receiving an upgrade to Buy from Benchmark's Gary Mobley, who thinks the present royalty value of MIPS' patent portfolio is $3.40/share, or nearly half its current stock price. Mobley adds a court could find "some portion of MIPS' competition" is violating its IP. It was reported last month that MIPS has hired Goldman to find a buyer, and a later report claimed AMD is among the interested parties.
