Shorts are dangerous. Wipe them out with a serious initial dividend later this year. Maybe after the next big upfrong cash payment.
The big boyz with big short positions have to pay those dividend. Big one time payments will shake them to their bone. You end up with a much better price for the stock and the chance to raise funds via an offering. If settlements continue every month or so it would allow Rambus to continue to grow the cash position.
I've been in stocks in similar positions that used the dividend tactic and it worked well.
