<584 – Adverse Markman overcome. NEC/Toshiba requests overcome – New Claim 29, new claims don't suffer from adverse markman in TX. A recent (?) Fish and Richardson (F & R) request denied.>
It is preferable that claim 29 overcome the adverse markman. The alternative is a worthless patent with no ability to sue for past or future infringement. It was more than just ARM that was let off the hook when the appeal failed. I suspect you are correct in that Barco may not have enough 584 infringement to make it worth the effort.
