Rodime Plc, a London Stock Exchange-listed former disk drive manufacturer, found its share price leaping by 500% before lunch yesterday, as rumors circulated that an unnamed internet company is to reverse into it as a shell company. Rodime has not traded since the collapse of its disk business more than two years ago, but owns a number of disk-related technology patents, and has made a living suing the likes of Seagate Technology Inc since. The two-man Edinburgh, UK outfit had a market capitalization of 3.2m pounds ($5.1m) at close of business Friday, based on a share price of 1.25 pence. At close of business yesterday, the share price stood at 3.75 pence, a rise of 200% on the day, after 15 million shares had changed hand, giving a market cap of 9.5m pounds ($15.5m).
