Is corroboration of evidence necessary when the testimony regarding lack of authorization is provided by the inventor?

In the context of patent proceedings, particularly when assessing issues of inventorship and authorization, corroboration of evidence is critical in ensuring the credibility of the testimony provided. When an inventor testifies about a lack of authorization, having independent evidence to support that testimony strengthens the case.

Independent corroboration serves multiple purposes: it adds reliability to the claim made by the inventor, demonstrates that the claim is not simply a unilateral assertion without backing, and aids in fulfilling the burden of proof, which may vary depending on the specific legal standards in place during patent disputes. For instance, corroboration can include documentation, witness statements, or other physical evidence that substantiate the inventor's assertions.

Without this corroboration, the testimony may be viewed as less credible, potentially undermining the case's overall strength. Thus, utilizing a robust corroboration strategy is vital in patent law proceedings to reinforce the credibility of the inventor's claims regarding authorization. This understanding underscores why independent evidence is necessary in this scenario.
