The patent application was filed by Mac Trailer Manufacturing, Inc. for a dump body with access door. It was filed on April 24, 2018 before being approved on Dec. 14, 2021.
Though patents are required for inventions and products, the granting of a patent is not a guarantee for success. Dennis Crouch, co-director of the Center for Intellectual Property & Entrepreneurship, said roughly 50 percent of patents expire prematurely due to costs.
There were three patents granted for Alliance inventors in December.
