btw, if we had development agreements .....which i don't know if we do have any...

..i'm sure they'd be subject to NDAs, therefore, your answer would have to be in two parts,

1. how long if under a development agreement,

2. how long if not,

good luck

ps we licensed a manufacturer WITHOUT litigation about 2 years ago, don't remember exactly when....hmmmmm

pss web cast 3/14/11 edig stated we would let partners "bear out that work" or something to that effect, right???
