ALEXANDRIA, Va., Aug. 12 -- United States Patent no. 12,704,411, issued on Aug. 11, was assigned to X-RITE Inc. (Grand Rapids, Mich.).

"Delta E formula match prediction" was invented by Robert Willis (Greensboro, N.C.) and Thomas Michaels (Grand Rapids, Mich.).

According to the abstract* released by the U.S. Patent & Trademark Office: "A method of determining a color formula for a target color begins with generating a plurality of candidate color formulas to reproduce the target color. For each candidate formula, a predicted delta E indicating a difference from a predicted color for the candidate formula from the target color is determined. Also for each candidate formula, a confidence value in the predicted delta E is generated by summin...
