Does the phrase "purchased patent right" conform to the definition of assets? Why?

Meet the definition of assets. Assets refer to resources formed, owned or controlled by an enterprise through past transactions or events, which are expected to bring economic benefits to the enterprise.

The word "purchase" means that the enterprise already has its ownership. Patent right belongs to intangible assets and is a kind of resource. The "patent right" is expected to bring economic benefits to enterprises, otherwise it will not be "purchased".
