Terminal disclaimers are statements that are specifically used to overcome double patenting rejections in the patent prosecution process. When two or more patents are granted for the same invention or if a later patent’s claims are not patentably distinct from an earlier patent, the United States Patent and Trademark Office (USPTO) may reject the later patent application on the grounds of double patenting.

To address this issue, an applicant can file a terminal disclaimer, which is a legal document that essentially states that the term of the later patent will be limited to expiring at the same time as the earlier patent. This serves to prevent the applicant from extending their exclusive rights through the later patent in a way that could unjustly extend the patent term beyond the original patent's expiration. As a result, terminal disclaimers play a crucial role in maintaining the balance between protecting inventors' rights while also ensuring that the public can access the underlying inventions once the patent terms have expired.

The other options do not pertain to the purpose of terminal disclaimers. They do not relate to the management of patent terms or addressing rejections based on overlapping patent claims. Instead, terminal disclaimers are focused specifically on resolving issues of double patenting, which is pivotal in patent law.
