If its your property, you should legally speaking tell any OTHER company to rightly fuck off about restrictions on your property.
Intellectual property rights (copyright, patent, trademark) should NOT have any ground in restricting property rights of things directly owned. Instead, we see shit like Iphones where they use the term "SELL", and then continual and ongoing restrictions by the FORMER OWNER.
If a company wants to maintain control, they should RENT it, with an explicit, simple to read rental agreement.
