Hey sus girl
from what I understand, they have had several prior art submissions from webmasters .. just as RawAlex mentioned so this should get interesting very soon.
actually a lawsuit wouldn't have been necessary to overturn a patent. It's a normal proceeding to have a patent re-evaluated and their office research crew can do the deed. The rub here is that lawsuits have evidently already been filed. If the lawyers had requested the re-evaluation before that time it would have been much better cost wise - then leave more legal fees for smacking acacia upside the head in court for damages etc
I suppose time will tell
