INPEX (Invention and New Product Exposition) is America's largest invention trade show, organized by InventHelp. The annual show is held each June in Pittsburgh, Pennsylvania.
INPEX provides a forum for inventors to exhibit their inventions and pitch their ideas with companies interested in licensing, marketing or manufacturing their new products.
This trade show also hosts contests for domestic and international inventors (45 different categories), as well as seminars and workshops for both inventors and business attendees within the George Foreman Inventors University.
The annual sponsor and producer of INPEX, InventHelp, also helps inventors to protect their ideas, and if necessary, obtain a patent prior to their participation in the show.
Inventions at INPEX range from simple products to highly technical devices that can be displayed as models or prototypes or as a finished product for the mass market.
