marketable title to the Vitesse Patents, including without limitation all
rights, title, and interest in the Vitesse Patents to sue for infringement

assigns harmless from (i) any third party
claims against Purchaser, its Affiliates and their respective
officers, directors, employees, distributors, agents, successors and assigns arising
