The Verdict & Legal Analysis
Litigation Timeline & Procedural History
| May 22, 2024 | Complaint filed by Patent Armory, Inc. |
| June 18, 2025 | Court notes no service or action taken |
| June 20, 2025 | Show cause order issued (14-day deadline) |
| August 7, 2025 | Case closed — dismissed without prejudice |
Outcome
The case was dismissed without prejudice — meaning no merits ruling on patent validity, infringement, or damages was ever reached. No injunctive relief was granted or denied. No damages were assessed. The dismissal was entirely procedural.
Verdict Cause Analysis
Under FRCP 4(m), plaintiffs must serve defendants within 90 days of filing a complaint. Armory’s apparent failure to serve Ledo Pizza for over 13 months far exceeded this threshold by any standard.
FRCP 41(b) additionally authorizes involuntary dismissal for failure to prosecute — a doctrine that courts invoke when plaintiffs demonstrate prolonged inaction. Combined with Maryland’s Local Rule 103.8, which reinforces these procedural obligations at the district level, the court had clear and compounding grounds to dismiss.
No record of a response to the show cause order appears in the available case data, suggesting Armory either could not demonstrate good cause or chose not to contest dismissal — potentially indicative of a strategic decision to abandon this particular target or refile under revised circumstances.
