What is the purpose of limiting prior art submissions during reexamination?

The limitation on prior art submissions during reexamination proceedings serves a specific purpose. As stated in MPEP 2204:

“The purpose of this rule is to prevent harassment of the patent owner due to frequent submissions of prior art citations during reexamination proceedings.”

This rule helps maintain the integrity of the reexamination process by preventing potential abuse through excessive or unnecessary prior art submissions, which could unfairly burden the patent owner or delay the proceedings.
