ExacTac Picture Hanging Tool: Multi-Defendant Patent Verdict Against E-commerce Sellers

Case Overview

The Parties

Patents at Issue

This case involved two U.S. patents covering the ExacTac Picture Hanging Tool, a consumer device designed for precise picture mounting:

• • U.S. Patent No. 10,441,098 B2 — directed to a picture hanging tool invention with specific structural and functional claim elements designed to simplify level, precise picture mounting.
• • U.S. Patent No. 10,047,903 B2 — a related patent in the same technology family, covering earlier claim iterations of the ExacTac hanging tool system.

Litigation Timeline & Procedural History

The case, filed on August 15, 2022, in the Central District of California, involved a multi-defendant “Schedule A” complaint targeting numerous overseas e-commerce sellers. The litigation concluded on February 3, 2025, taking approximately 2 years and 6 months to resolve through default judgments.

The case proceeded through a series of individual defendant motions rather than a unified trial. The court adjudicated at least seven separate default judgment motions, each addressing a distinct defendant’s liability and damages amount, consistent with the typical trajectory of such multi-defendant actions where overseas sellers often fail to appear or respond.

The Verdict & Legal Analysis

Outcome

The court granted all seven pending default judgment motions, entering judgment in favor of Plaintiffs against the following defendants with individualized damages awards totaling nearly $9,631:

Verdict Cause Analysis

The verdict cause is classified as “Other Action,” consistent with default judgment proceedings where defendants failed to appear, contest liability, or challenge the asserted patents. In default judgment scenarios, courts typically accept well-pleaded allegations of infringement as admitted, limiting substantive legal analysis of claim validity or construction on the merits.

Legal Significance

Several legally significant features emerge from this case:

• • Pro Se Enforcement Viability: Bruno’s success as a pro se litigant in a multi-patent, multi-defendant action signals that the Schedule A framework—while complex—is accessible to individual inventors willing to invest the procedural effort.
• • Damages Proportionality: The granular, defendant-specific damages amounts suggest the court engaged in individualized damages analysis for each motion rather than applying a uniform formula. Patent practitioners should note that even in default proceedings, documentation of defendant-specific sales data matters to the damages calculation.
• • Schedule A Litigation Mechanics: The case reinforces that coordinated multi-defendant e-commerce enforcement remains viable in the Central District of California, with courts willing to adjudicate staggered default motions across a large defendant pool.
