A ground for dismissal based on defects in the form or content of the summons. The defects include failure to name the correct court or parties or to state a proper time for appearance. Actual notice to the defendant does not cure such formal deficiencies.
Isla Ireland filed suit in federal court against Insight Consulting. Her attorney issued a summons that misnamed the defendant as Insight Consultants and listed an appearance deadline already expired. Insight Consulting moved to dismiss under Rule 12(b)(4). The court granted the motion because the summons failed to satisfy the formal naming and deadline requirements on its face.
Ivan Ivanov sued Integrity Partners in the District of State A. The summons obtained from the clerk named the District of State B instead. Integrity Partners moved to dismiss. The motion succeeded because the summons did not name the court in which the action was actually pending.

Defects in the form or content of the summons itself trigger the motion. These include misnaming the court or parties and stating an impossible appearance deadline. The rule focuses on the document's facial compliance rather than the method of delivery.
Supporting sources
No. Actual notice does not excuse formal defects that render process insufficient. Courts require compliance with the specific requirements for the summons even when the defendant learns of the suit through other means.
Supporting sources
Insufficient process addresses defects in the summons document itself. Insufficient service of process concerns the manner or method of delivering the papers. The two defenses are raised under separate subdivisions of Rule 12(b).
Supporting sources
No. A defendant must consolidate all available Rule 12(b)(2) through (5) defenses in the first pre-answer motion. Omitting the defense waives it for later motions even if the second motion is filed before an answer.
