Judging from this post as well as previous posts, I am confident that you are not missing anything. We must hope that the company and attorneys also realize this and negotiates accordingly. From a complete novice-- it seems critical to know which infringers are left in the mix if the changes are made and which are not so one could make a decision based on potential future income. If one or two biggies are left in, it may make sense to make the changes.
