Which requirement is true regarding a 1.130(b) affidavit?

A 1.130(b) affidavit serves to provide evidence of prior art that is relevant to the claims being made in a patent application. Specifically, this type of affidavit must establish not only the date of the prior disclosure but also its content to substantiate that the applicant is indeed relying on an earlier public disclosure to overcome an obstacle that may arise during the patent examination process.

By providing both the date and details of the prior public disclosure, the affidavit helps to establish that the claim being presented is not novel due to the prior art, which is critical in resolving any rejections related to novelty or obviousness. This requirement ensures that the examiner has sufficient information to assess the validity of the claims in light of existing public knowledge, making the affidavit a key document in the application process when claiming priority to earlier disclosures.

The other options each refer to aspects that either do not represent requirements of a 1.130(b) affidavit or misinterpret the content necessary for an effective submission.
