There is zero mechanism under patent law to enforce what you are referring to. Patent law is about selling items not consuming them so they could prevent me from selling a clone of office but they cannot prevent me from installing office as far as contract law that would be between two parties so if I obtained a copy of office somewhere and I did not have a contract with Microsoft nothing I would not be violating a contract with Microsoft copyright is the only mechanism they use to stop unauthorized distribution of their software
