RH Peterson Co. was issued U.S. Patent D857,453 by the U.S. Patent and Trademark Office for its revolutionary Diamond Sear cooking grids. The grids’ unique trapezoid-shaped design delivers more heat to the surface of the grill, retaining juices in the food and ultimately providing superior cooking results.

Available in various types and sizes, the Diamond Sear grids are featured on Fire Magic and American Outdoor Grill (AOG) models. The tops of each individual bar of the Fire Magic grids measure 0.33 inches wide throughout and, in total, cover up to 50% of the grill’s cooking area. The AOG cooking grids are slightly smaller at 0.28-0.29 inches wide and cover 40-45% of the surface of the AOG.

Introduced in 2018, the Diamond Sear cooking grids were designed by RH Peterson employees David Keck, David McCullough, Boris Gorelik, and Jon Bridgwater. “Another first for Peterson, continuing the spirit, dedication and craftsmanship of our founders Bob Peterson and Harold Keck,” says president Leslie Bortz. “Our trapezoidal Diamond Sear cooking grids represent another step in Fire Magic’s 80-year history of developing innovative outdoor grilling products that uniquely meet consumers’ needs.”
