Source: FAQ (MPEP-Based)BlueIron Update: 2024-09-10

This page is an FAQ based on guidance from the Manual of Patent Examining Procedure. It is provided as guidance, with links to the ground truth sources. This is information only: it is not legal advice.

While MPEP 706.07(e) discusses the withdrawal of final rejections to apply new grounds of rejection, it refers to MPEP § 1207.03 for a detailed discussion of what constitutes a new ground of rejection. The manual states:

“See MPEP § 1207.03 for a discussion of what may constitute a new ground of rejection.”

Generally, a new ground of rejection may include:

  • Citing a new reference that was not previously relied upon
  • Relying on a different portion of a previously cited reference
  • Changing the statutory basis of the rejection
  • Presenting a new factual finding or reasoning to support a rejection

It’s important to note that determining whether a rejection constitutes a new ground can be complex and depends on the specific circumstances of each case. Patent examiners and applicants should carefully review MPEP § 1207.03 for a comprehensive understanding of this topic.
