The Minnesota Inventors Congress, which draws inventors from around the country for its annual events, is seeking exhibitors for the 2014 “Invention Expo”—which will be held in the Twin Cities for the first time.

The Minnesota Inventors Congress began in 1958, and Twin Cities Business examined its history in a 2011 feature story. The event has attracted thousands of independent inventors and is the oldest of its kind in the nation. After a 56-year run in its home community of Redwood Falls, the event moved to the Twin Cities this year.

The event will be held at the Minneapolis Convention Center on May 2 and 3, and it will include booth displays for inventions, as well as workshops designed to teach inventors and attendees how to successfully develop and market their products. Exhibitors may also compete for various awards, and 30 inventors will have the opportunity to pitch their products before “national product scouts.”

The cost for exhibiting, if paid by April 4, is $595, or $695 thereafter. Learn more about the registration process here.

“The annual Invention Expo connects exhibiting inventors with the best resources to help them get their products to market—from experts on intellectual property and patents, to authorities on funding, manufacturing, and licensing, and new customers for market testing and word-of-mouth promotion,” Doug Reuter a past exhibitor, said in a statement. “Exhibiting at Invention Expo is one of the most valuable commitments that inventors can make.”
