Litepanels v. Godox: LED Lighting Patent Dispute Ends in Default Judgment

Introduction

In a patent infringement dispute that illuminates the complexities of pursuing both domestic distributors and foreign manufacturers, Litepanels, Ltd. secured a partial default judgment against Chinese lighting manufacturer Shenzhen Godox Photo Equipment Co., Ltd. while simultaneously resolving claims against U.S.-based defendants through confidential settlement. Filed in the Southern District of Ohio in August 2022, Case No. 2:22-cv-03143 — consolidated with Case No. 2:22-cv-3235 — centered on three patents covering LED-based photographic lighting technology and a sprawling product lineup of over 100 accused Godox devices.

The case’s outcome reflects a pattern increasingly common in LED patent litigation: domestic resellers settle quietly while the foreign OEM defaults, leaving indirect infringement claims unresolved. For patent attorneys, IP professionals, and R&D teams operating in the professional photography lighting sector, this case offers critical lessons in assertion strategy, default judgment limitations, and freedom-to-operate risk.

Case Overview

The Parties

The Patents at Issue

Litepanels’ infringement assertions focused on three foundational United States patents related to LED-based photographic and cinematographic lighting systems:

• • US7,972,022 B2 — LED-based photographic lighting with adjustable characteristics
• • US7,318,652 B2 — Integrated LED light panel systems for film and video production
• • US7,510,290 B2 — Methods and apparatus for controlling LED light output

Litigation Timeline & Procedural History

The case was filed on August 16, 2022, in the U.S. District Court for the Southern District of Ohio, spanning 1,291 days before final closure on February 27, 2026 — a litigation duration of approximately 3.5 years. Ohio venue selection was strategically logical given the presence of domestic defendants Midwest Photo Exchange and MPEX Distribution in the region.

The two related actions (2:22-cv-03143 and 2:22-cv-3235) were consolidated, streamlining proceedings involving the overlapping defendant and product sets. A critical procedural turning point arrived in April 2025, when the Court granted Litepanels’ motion for default judgment against Godox on direct infringement claims following Godox’s failure to appear or defend.

However, the Court simultaneously denied the motion as to indirect infringement (including induced and contributory infringement claims), ordering Litepanels to show cause why those claims should not be dismissed for failure to adequately plead them. Litepanels did not respond to the show cause order, resulting in the dismissal of indirect infringement claims without prejudice. The non-defaulting defendants — Midwest Photo and MPEX — jointly stipulated to dismissal with prejudice of all claims against them pursuant to Federal Rule of Civil Procedure 41(a)(1)(A)(ii), reflecting a negotiated settlement whose financial terms were not disclosed in the record.

The Verdict & Legal Analysis

Outcome

The consolidated litigation concluded with a bifurcated resolution:

• Default judgment entered against Godox on direct patent infringement claims (April 2025)
• Indirect infringement claims against Godox dismissed without prejudice (February 2026) after Litepanels failed to respond to the Court’s show cause order
• Claims against Midwest Photo and MPEX dismissed with prejudice pursuant to a confidential settlement agreement

No specific damages award amount was disclosed in the public record. The Court notably declined to retain jurisdiction to enforce the settlement agreement between Litepanels and the non-defaulting defendants — a significant procedural choice that shifts any future enforcement disputes to separate breach-of-contract proceedings.

Verdict Cause Analysis

The case hinged on direct and indirect infringement of three LED lighting patents. The Court’s differentiation between direct and indirect claims against the defaulting Godox defendant reveals an important doctrinal boundary: even in default judgment posture, courts scrutinize whether complaints adequately plead the elements of induced or contributory infringement — including knowledge of the patent, specific intent to cause infringement, and the existence of direct infringement by a third party.

Litepanels’ failure to substantively respond to the show cause order regarding indirect infringement was a significant strategic misstep. Whether the decision reflected a litigation resource calculation, a settlement-focused pivot, or an acknowledgment of pleading weakness, the result was the dismissal of potentially valuable claims without prejudice — preserving theoretical refiling rights but forfeiting immediate relief.

Legal Significance

This case reinforces that default judgment in patent cases is not automatic or unconditional. Courts independently assess whether the pleadings support each cause of action, even when defendants are absent. The distinction between direct and indirect infringement claims at the default judgment stage is instructive for patent litigants structuring complaints against supply chain defendants.

Additionally, the court’s refusal to retain jurisdiction over the settlement is a reminder that drafting enforceable settlement agreements in patent cases requires careful attention to dispute resolution mechanisms independent of the underlying litigation court.
