CINCINNATI -- The University of Cincinnati is suing Crayola after it says the toy maker used patented light-source technologies to come up with some of the items in its Glow product line.

The complaint filed Monday in U.S. District Court by Ohio Attorney General Mike DeWine states Crayola used inventions created by UC’s optical-physics researchers in several of its products, according to an article in the Columbus Dispatch. The toys include the Glow Board, Glow Dome and Glow Book.

Crayola was asked to stop using the technology and pay the University of Cincinnati damages for “willfully” undermining the school’s patent, according to the Dispatch report.

“To protect our faculty who pursue useful research, and the taxpayers who support them, the university will take action to defend the rightful ownership of our intellectual property,” the school said in a statement.

The Dispatch reports one of the inventors listed on UC's patent application is in charge of the university’s Novel Devices Laboratory. The lab is known for its work in reflective displays, according to the lab's website.

The lab says it has partnered with numerous U.S., European and Asian companies in "pushing new technologies to market" since 2006.

Crayola Glow toys allow users to draw with glowing markers on reusable surfaces.

Neither lawyers for the university nor representatives for Crayola were available for comment.
