What is the maximum number of items that can be included in a request for supplemental examination?

In the context of supplemental examination, the maximum number of items that can be included in a request is indeed 12. Supplemental examination allows a patent owner to request the United States Patent and Trademark Office (USPTO) to consider, reconsider, or correct information believed to be relevant to the patent. This is particularly aimed at addressing potential issues related to patent validity.

The rules state that a request for supplemental examination must identify all items of information that the requester wants the USPTO to consider. The limitation of including 12 items in such requests serves to focus the examination process. By capping the number of items, the USPTO can manage its review process more efficiently while still allowing patent owners the opportunity to have multiple pieces of information reviewed for relevancy.

While other options suggest different maximum numbers, only the figure of 12 aligns with the established regulations regarding supplemental examination. This specificity is important for patent owners to understand as they navigate through the supplemental examination process.
