What if the purchased equipment does not have the patent of the other party?

Apply for a patent after purchasing the equipment and find other protection measures.

1. Apply for a patent after purchasing the equipment: I think the equipment is innovative and has commercial value, so I can apply for patent protection by myself.

2. Find other protection measures: Even if the equipment is not patented, I can still protect my rights and interests in other ways. For example, I can sign a confidentiality agreement with the supplier to ensure that the technical details and business secrets of the equipment will not be leaked.
