What statement must a 1.130(a) affidavit include?

A 1.130(a) affidavit must include an unequivocal statement that the inventor invented the subject matter. This requirement is essential because the purpose of the affidavit is to establish the inventor's entitlement to the claimed invention based on their original contributions. By providing an unequivocal declaration, the inventor affirms their role in the conception and reduction to practice of the invention, which is crucial for the integrity of the patent application process.

This type of affidavit is particularly relevant when addressing issues of inventorship or when asserting that the inventor has not abandoned their rights to the claimed invention. It serves as a formal acknowledgment of the inventor's contribution, thereby helping to clarify any potential disputes regarding who should be recognized as the rightful inventor.

Understanding this context enhances the significance of having a clear and direct statement about the inventor's role in the creation of the invention, which is not met by the other options provided. The other choices do not address the key requirement of demonstrating the inventor's direct involvement with the subject matter at hand.
