his "Hutson toothbrush" was filed on January 13, 1950, and U.S. Design Patent No. 160,604 was granted on October 24 the same year.

In 1958, he was granted a utility patent for a "mouthbrush" having fine, soft, flat-ended nylon bristles, and a similar appearance to the 1950 design. He claimed in his application that the brush was less abrasive to tooth enamel, more effective at massaging the gums, and better at picking up tooth powder than other brushes available at the time, which featured coarse, angle-cut bristles.
