Industry-defining inventions of Granger-seated firms — the tested negative

SEARCH RUN WHOLE, NOVEMBER 2026 · NO FIRM PATENT FOUND

The Businesses leg banks the frame: no plant of scale has ever been seated in the designated place, and its making layer is four names — Triangle Truss, Big C Lumber, Drive & Shine, and Anchor Construction — plus a taproom-scale brewery. The answer is a clean negative, firm by firm. Big C Lumber (headquarters 50860 Princess Way) designs and manufactures trusses, wall panels and millwork at real scale, but the record reached holds no Big C patent: what the search returned was a trademark application for the BIG C LUMBER name and a home-plan copyright lawsuit, Design Basics v. Big C (N.D. Ind. 3:16-cv-53, opinion 22 July 2019) — litigation about plans, not invention. Drive & Shine (headquarters 16915 Cleveland Road, founded 1997, owner Haji Tehrani) states in its own recruiting copy that "we design and manufacture most of the equipment that we use in our buildings" — the strongest inventive claim any Granger firm makes for itself — and no patent, and no assignee record under the firm or its owner's name, was found behind it; the car-wash patents the search returned belong to other companies in other states. The equipment claim therefore prints as unpatented: designed and built, on its own telling, but never carried into the patent record. Anchor Construction LLC (7121 Grape Road, founded 2006, design-build work in more than forty states) returned no patent under its name; the "anchor construction" patents the index offers are boat anchors and ground anchors by unrelated inventors. Triangle Truss, which manufactured roof trusses on the present Big C site from 1972 to 1976, holds no patent in the record reached either; truss manufacture was already a mature national industry when it arrived, and nothing in the county histories or the trade file credits the Granger shop with changing it.
