Litigation Timeline & Procedural History

📊 Key Dates:

• Filed: February 1, 2024
• Closed: July 7, 2025
• Duration: 522 days (~17 months)

The case proceeded through the Ohio Northern District Court under Chief Judge Donald C. Nugent (MDL3093). The 17-month duration reflects a moderate timeline for patent litigation at the district court level—neither expedited nor unusually prolonged.

The procedural record (accessible via PACER) culminated in ECF #38, the Stipulation of Dismissal filed by both parties. The settlement occurred before any substantive rulings on claim construction or patent validity.

💡 Key Insight: Settlement before claim construction often indicates both parties identified significant litigation risks—either to patent validity or infringement findings—making negotiated resolution economically preferable.

The Verdict & Legal Analysis

Outcome

The court’s order states: “The parties have informed the Court they have resolved all issues between them and reached a stipulated settlement… this case is dismissed with prejudice; each party to bear its own costs.”

Dismissed with prejudice means Golden Rule cannot refile these specific infringement claims against R.P. Lumber for the accused products. Settlement terms remain confidential, as is typical in patent infringement settlements.

Verdict Cause Analysis

This infringement action terminated through negotiated resolution rather than judicial determination. Without disclosed terms, practitioners may consider several possibilities:

• Licensing agreement – R.P. Lumber may have secured rights to continue selling accused products
• Design-around commitment – Defendant may have agreed to modify products
• Financial settlement – Undisclosed damages or royalty arrangements
• Mutual release – Both parties agreed to walk away without admission

The absence of willful infringement findings or prior art challenges in the public record suggests both parties recognized litigation uncertainties. Track litigation trends with Patsnap Eureka IP for comparable settlement patterns.
