Bulldog, odds are that each accused "infringer" will want separate litigation. Since there is a penalty of treble damages for "willful" infringement, they won't want to be all lumped into one legal action.
I'm pretty sure that each defendant will want to mount their own defense, since circumstances in each case will be or at lease will try to be made to seem different. Also, some if not all of the suits may be filed in different states or even countries.
Also, as each case comes to trial, the follow on defendants will be watching the strategies used and how successful they are.
All on MHO, of course!
