Patent 9220959 was granted and assigned to Cobra Golf on December, 2015 by the United States Patent and Trademark Office.
The invention relates to golf club heads with improved mass distribution provided by novel cellular features. Because a club head can have very low mass density in certain parts, the club head can have much more mass in other parts, while keeping the overall club head mass equal to the mass of prior art club heads. A club head can be provided with optimized MOI and CG. The novel cellular structures of invention provide extensible functionality in the form of pockets, recesses, and windows and provide materials with excellent strength and restitution properties.
