Is patent transfer a patent change? What's the difference between them?

Patent transfer means that the transferor is the patentee, and the ownership or holding right of the patent is transferred to the transferee, who pays the agreed price. Patent transfer includes the transfer of patent right and patent application right.

Patent change can be some information change of the patentee, but when we carry out the patent change procedure, we are often called changing the patentee.

And the focus of the two is different. Patent transfer is a way of trading patents, or directly giving patented technology to others. However, patent changes are different. It may be just some details of patent changes, or it may be just a transfer transaction. Generally speaking, patent transfer is equivalent to patent change, but patent change is not equivalent to patent transfer.

This depends on the specific content and cannot be generalized, so this concept will be ambiguous.
