A more thorough explanation:

Definition: A motion to correct inventorship is a request made in a patent interference proceeding to add one or more unnamed coinventors to the patent application. This motion will be granted unless there is evidence to suggest that the proposed inventor(s) did not contribute to the invention.

Example: Let's say that John and Jane filed a patent application for a new type of solar panel. However, they later discovered that their colleague, Bob, had also contributed to the invention. In this case, John and Jane could file a motion to correct inventorship to add Bob to the patent application as a coinventor.

Explanation: The example illustrates how a motion to correct inventorship can be used to add a previously unnamed coinventor to a patent application. In this case, John and Jane realized that Bob had contributed to the invention and wanted to ensure that he received credit for his work. By filing a motion to correct inventorship, they could add Bob to the patent application as a coinventor.
