Case Overview
The Parties
⚖️ Plaintiff
Individual inventor holding U.S. Patent No. 8,317,244, a patent directed to counterweight cantilever technology.
🛡️ Defendant
One of North America’s most recognized specialized heavy rigging and transportation companies.
The Patent at Issue
This case involved **U.S. Patent No. 8,317,244**, covering a Moveable Counterweight Cantilever System (MOCCS) used in heavy crane and rigging operations:
- • US 8,317,244 B1 — Moveable Counterweight Cantilever System (MOCCS) for crane operations

The Verdict & Legal Analysis
Outcome
Judge Robart issued **Judgment by Court** granting Barnhart’s motion for summary judgment and simultaneously denying Schuyleman’s cross-motion for summary judgment. The court dismissed the action **with prejudice** — a terminal outcome foreclosing any refiling of the same claims.
Key Legal Issues
The most strategically significant element of this outcome is that Barnhart succeeded **on its invalidity counterclaim** at the summary judgment stage. This indicates the patent’s claims likely faced substantial prior art challenges, failing to meet statutory requirements under 35 U.S.C. §§ 102 or 103.
