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

The initiation of derivation proceedings requires a demonstration of substantial evidence of derivation. This means that a party must indicate that another party has claimed ownership of an invention that the first party has actually invented. The evidence must satisfactorily show that the first party's invention was derived from the second party's work. The focus here is on the connection and the circumstantial evidence that could support claims of derivation, which is a key aspect in proving that the accused party obtained the information or concept from the original inventor without proper authorization.

While the other options may touch upon excellent practices or considerations in the context of derivation proceedings, they do not encapsulate the core requirement as clearly as the necessity for substantial evidence of derivation. This requirement ensures that the allegations are robust and merit the procedural steps involved in a derivation proceeding. It's important to note that simply alleging or claiming derivation without substantial evidence would not suffice to initiate the legal process.
