Case Overview
When an appellate patent case closes not on the merits but on procedural grounds, the outcome carries its own distinct warning for IP litigants. In *Imprenta Services, Inc. and Mike Sanchez v. Nicholas Patrick Karll and Eco Packaging Solutions* (Case No. 23-2157), the U.S. Court of Appeals for the Federal Circuit dismissed the appeal on March 7, 2024, after just 232 days — not because the underlying patent infringement claims were adjudicated, but because the appellant failed to prosecute the case in accordance with appellate rules.
At the center of this metal child-resistant container patent infringement dispute was U.S. Patent No. US10513375B2, a packaging technology with direct commercial relevance in regulated consumer product markets. The case serves as a critical reminder that even technically sound patent assertions can be neutralized by procedural missteps — a lesson with broad implications for patent attorneys, IP professionals, and R&D teams navigating enforcement strategy.
The Parties
⚖️ Plaintiffs
Plaintiffs pursuing patent infringement claims, with Imprenta Services operating as the primary corporate plaintiff. The inclusion of inventor or co-owner Mike Sanchez suggests a co-ownership or licensing arrangement tied to the asserted patent.
🛡️ Defendants
Defendants representing both an individual and a corporate entity. Eco Packaging Solutions, as the business entity, was likely the commercial actor whose product activity formed the basis of the infringement allegations.
The Patent at Issue
This case involved U.S. Patent No. US10513375B2, a packaging technology with direct commercial relevance in regulated consumer product markets. The claims of US10513375B2 cover a metal container designed to resist opening by children while remaining accessible to adults.

The Verdict & Legal Analysis
Outcome
The Federal Circuit **ordered the notice of appeal dismissed for failure to prosecute** in accordance with the court’s rules. No damages were awarded, no injunctive relief was entered, and the merits of the patent infringement claims — including validity, claim scope, and infringement — were never reached on appeal. The dismissal is a procedural termination, not a ruling on whether US10513375B2 was infringed or valid.
Key Legal Issues
The Federal Circuit’s dismissal for **failure to prosecute** indicates the appellant did not fulfill mandatory procedural obligations — such as filing opening briefs, appendices, or other required submissions within prescribed deadlines. The case closed in under eight months, a notably short appellate lifespan, reflecting not efficiency but abandonment. The outcome underscores that initiating an appeal without the infrastructure to complete it carries significant strategic risk.
For practitioners, the case reinforces the Federal Circuit’s adherence to Federal Circuit Rule 47.4 governing appearances and Rule 31 governing brief deadlines. The court has minimal tolerance for non-prosecution.
