Protecting Creative Ideas Since 1958

For over 60 years, Head, Johnson, Kachigian and Wilkinson, PC has been the premier name in Intellectual Property law in Oklahoma. Established in 1958, this firm has a storied history of helping inventors, artists, and businesses protect their creations. Unlike general practice firms, we are 100% dedicated to IP law. We have grown from a small local practice into a major firm securing and enforcing rights for clients across the United States and internationally. When you work with us, you are leveraging decades of institutional knowledge and a track record of success.

Technical Expertise

Our attorneys are not just legal experts; they are technical specialists. With backgrounds in mechanical, electrical, chemical, and biotechnological fields, we speak the language of your invention. We understand that a patent is worthless if it doesn’t accurately describe the innovation.

• Patents: We handle the entire lifecycle of a patent, from the initial novelty search to drafting the application and fighting for its issuance before the USPTO.
• Trademarks: Your brand is your reputation. We conduct clearance searches and register trademarks to ensure your brand is uniquely yours.
• Litigation: If someone steals your idea or accuses you of infringement, our trial lawyers are ready. We have extensive experience litigating IP disputes in federal courts.
• Entertainment and Franchising: We advise on the unique IP needs of the entertainment industry and help businesses expand through franchising.

Our office is located at 7134 S Yale Ave, within the Executive Center II building. This location at the intersection of 71st and Yale places us in one of Tulsa’s busiest commercial corridors, offering easy access for clients.
