A 1.130(a) affidavit must demonstrate which of the following?

A 1.130(a) affidavit is primarily concerned with overcoming rejections based on the insufficient disclosure of the claimed invention, especially in the context of intervening prior art that may have arisen since the original filing. To effectively overcome such rejections, the affidavit must demonstrate enabling disclosure of the subject matter to establish that the applicant had provided sufficient detail for a person of ordinary skill in the relevant field to make and use the invention.

Enabling disclosure refers to the requirement that the patent application must provide enough information regarding how to make and use the claimed invention without undue experimentation. This is a fundamental principle of patent law, ensuring that patents do not grant monopolies on inventions that are not fully disclosed or are not sufficiently accessible for others to replicate.

The other options do not accurately capture the primary purpose of a 1.130(a) affidavit. While it’s important to consider relevance of prior art, show a relationship to the applicant, or disclose a similar invention, none of these elements are necessary to fulfill the requirements of a 1.130(a) affidavit. The emphasis remains on enabling disclosure as the essential factor the affidavit must demonstrate.
