Litigation & Dispute Resolution

Successful companies aggressively enforce and defend their IP rights in the global market. IP litigation, however, can be extremely complex and the stakes are usually high. Our legal skills and technical, scientific, and industry experience give you the advantage in any dispute. We understand the inherent risks of litigation, whether to a product line, a business unit, or an entire business. We work with you to understand your desired outcomes and develop a litigation strategy that advances your business goals.

IP disputes involve complex scientific and technical information. COJK attorneys — many of whom have technical degrees - are skilled at presenting extraordinarily complex, technical cases to a judge or jury in an understandable way. We utilize technical experts to your advantage and explore all available options to challenge validity or develop original infringement claims.

We handle all types of IP matters and disputes, including cases that involve patents, trademarks, trade dress, trade secrets, copyrights, and license agreements and contracts. We have represented clients ranging from entrepreneurs to multinational corporations, across a diverse array of industries.
