SCUF Granted Another Key Gaming Controller Patent By USPTO

Four years after filing, SCUF gets utility patent for anti-friction rings, taking total to 150 granted & pending patents

ATLANTA, November 1, 2019Scuf Gaming®, innovator and creator of high-performance gaming controllers, through its patent subsidiary, Ironburg Inventions, has protected another key feature of gaming controllers with the recently issued US patent (#10,441,881).

This latest patent protects anti-friction rings in the thumbstick control area. The anti-friction rings have been designed to be customizable and removable, provide reduced friction between the controller and the thumbsticks, and enable the user to swap the thumbstick size, shape and design. Replaceable anti-friction rings are a necessary feature for esports professionals and competitive gamers due to performance advantages the rings offer.

With this new patent, Scuf Gaming now has 96 granted patents and designs, with an additional 54 pending patent applications.

“In 2011, we redefined the way gamers use their controllers by inventing the back control functions, adjustable hair triggers, and trigger stops. Since then, SCUF has been focused on improving several other key functional areas of the controller.” said Duncan Ironmonger, CEO and Founder of Scuf Gaming. “One such area is the thumbstick control region which is essential to peak performance and accuracy. By inventing the replaceable anti-friction rings, SCUF has created a solution to ensure thumbsticks can be swapped out and locked, while providing a low level of friction between the thumbsticks and the controller body. With this patent we are delighted to protect our innovation and investment for another key area of the controller.”
