Which of the following is true regarding the initiation of derivation proceedings?

The initiation of derivation proceedings necessitates that the party claiming derivation must present substantial evidence demonstrating that they are the true inventor and that the respondent derived their claimed invention from the true inventor. This process is critical as derivation proceedings are designed to resolve disputes over who is the rightful inventor of a claimed invention, particularly in situations where multiple parties have filed patent applications for similar inventions.

Substantial evidence may include documentation, witness testimony, or other relevant materials that convincingly establish the timeline and circumstances under which the inventions were made. This requirement is firmly established in the rules governing such proceedings, as it helps to ensure that only legitimate claims are raised in the patent system, thereby promoting fairness and integrity in the determination of inventorship.

While it is important to note that the other options mention necessary considerations, they do not accurately describe the core requirement for initiating a derivation proceeding.
