Thanks for posting, I agree with all points, but I'd like to add that I think it's better to be proactive than reactive.
Yes, we are owners of the patents and *should* benefit, but I don't want to wait for 'negative' things you reference to happen (Billy diverting funds to himself)
It's much more difficult and time-consuming to claw back ill-gotten gains than to prevent them from being 'ill-gotten' in the first place!
While your brother wouldn't be the one to take our case, I'd be interested on his take on the situation and any advice he may have for our group as we seek to defend our rights.
