Patent and Trademark

Patent Office

The former U.S. Patent Office, a Greek Revival building that was begun in 1836

The building that received the applications for patent and trademark protection for the revolutionary 2Fold® Folding door system was quite a bit newer than this one. After 18 months of design, testing and software development . . . “the world’s thinnest Folding door system,” was ready to unveil 2Fold™ to the world. Thanks to all who helped along the way to make It all possible.
