Thanks for asking... happy to bring you up to date.
Homegrown NEVER settled - in fact we are still in the case along with most of the other companies that chose to fight.
Our cost to fight went down years ago to almost nothing. Everyone always wanted to know why wasn't mainstream involved; well, as soon as Acacia sued mainstream, we were able to pretty much kick back and watch them spend their time and money to deal with Acacia. Since our Defense Group had already laid down our groundwork we got to watch while they played catch up.
A while back, Acacia tried to let us all off the hook with a sweetheart walkaway deal and we did not take it. Remember, if we invalidate the patents in the end then everyone gets off the hook. If we get out on just "non-violation" then those that chose to settle will still continue to pay and Acacia is free to keep going after people. I think I recall also that Acacia tried to invalidate parts of the patents themselves in an effort to preserve what little is left to protect that the Judge has already given them a hard time about. Members of the Defense Group had a good laugh about that ridiculous strategy.
Don't know when we go back to court but I can say that it is not looking good so far for those patent pirates. Maybe they can go get a job in Somalia when this is all said and done.
The people who settled have to keep paying for a bunch more years. People that just didn't respond I still would say, imo, that you shouldn't admit that since it is an inappropriate action under the circumstances because it was a legal notice - even if it did seem, like it did to us at first, to be a preposterous joke.
Well, I guess it still is a joke but we are still waiting for the Judge to deliver the final punchline in the case.
