The relevance of the content remains important, but the key point is that the application must be published to be admissible as prior art. If it has not been published, it does not meet the criteria under § 102(a) because it has not been disclosed to the public in any form.

The last choice misrepresents the role of withdrawal; it is the publication that determines prior art eligibility, not whether an application is explicitly withdrawn. Therefore, the publication of an abandoned application is the critical
