Nope..... Att and wbsi are previous partner using celsafety, THEN WBSI dropped out of the scene and att used drivemode which is similar to websafety. So technically they are infringing patent.
Websafety's assigned patent was filed in 2009. As an experienced patent filer, the date of filing NOT the date of issuance controls. Thus, Websafety's patent claims are secured as of 2009. And since they have one year to file from conception, their claims could be secured since 2008, if the idea was born in 2008.
THEREFORE, AT&T's DriveMode software that was started in and around 2011 infringes Websafety's patent.
