I cannot speak for other companies, do not follow them or care about them. Yes Doni has, the only IPR was with Google. The other companies received stays of their cases waiting for the results of the Google IPR. There will now not be one. So they can either file their own IPR or begin settlement talks knowing that Google settled for an unspecific amount. It is by no means a forgone conclusion what they will do. Chill out yourself.
