Spinal Resources Inc. received a Notice of Allowability from the United States Patent and Trademark Office, expanding the usage of its Bezier Parametric Curve Spinal Rod System. The patented system, US Patent No. 12,251,133, comprises a spinal rod system with different regions separated by a gradual transition region, wherein the curve and the length of the first and second segments and the transition region are customizable to a specific patient anatomy. 

The allowed claims specifically cover SRI’s innovative spinal fixation rod, which integrates multiple constant-diameter segments with smooth, tapered transitions across the rod’s entire perimeter. The design covered by these claims provides targeted strength and flexibility, critically avoiding the stress points associated with traditional sharp-stepped designs.

The patent’s focus on a constant-slope transition ensures a gradual and predictable stiffness profile, a key differentiator for biomechanical performance and long-term implant success.
