HOLDING

Manville won a patent infringement case against Paramount Systems over a lighting pole assembly design with special 'iris' guide arms. The court confirmed the patent was valid and that Paramount copied it, awarding damages to Manville. However, the court reversed personal liability against two individual company officers, meaning they couldn't be held personally responsible even though their company infringed. This matters to subcontractors because it shows patent disputes can result in major damages, but individual employees and managers may have some protection from personal liability.

KEY FINDINGS

Patent infringement can result in significant damages awards against your company—protect your designs and review competitor products carefully before copying
