Invention claims, tested: no "invented here" — but the patent record seats inventors on this ground by the page

1983–2026 · priority tested in the record that decides priority

The claim test, and its result: The pattern is the hometown priority claim — the starter, the forward pass, the device a town says was invented within its limits. None stands. No Granger inventor is celebrated for a first, no device carries this ground's name, and no priority dispute in the patent or sporting record names this place. The region's famous claims of the type live at their own addresses — the 1913 forward-pass game is Notre Dame's story, told in South Bend's build — and none of them touches the prairie. As a claim, the pattern is a tested negative.

What the patent record shows instead, at full size: Search the patent record by inventor residence, though, and the ground appears constantly — as a home address. Michael J. Pugia of Granger stands as inventor on a run of Bayer diagnostics patents through the 1990s (a creatinine-determination system, a molybdate-dye protein assay, a competitive apo-peroxidase assay, an ascorbate-resistant peroxide test — the dry-chemistry art behind the era's urine test strips), assigned to Miles and Bayer, firms seated elsewhere. John R. Erichsen of Adams Road, Granger, is a co-inventor on a sliding roadway sign. Edwin E. Ksieżopolski of Granger invented an edge seal for Lifetime Industries. Donald I. Ansbaugh of Granger patented a link-and-flight assembly for blast-treatment machinery in 1983. Thomas P. Benson of Granger co-invented a time-domain NMR analysis method for Ascensia Diabetes Care. Chester T. Chmiel of Kent Drive, Granger, co-invented an adhesive-tape composition for Bridgestone/Firestone; Colin Richard Bayliss of Granger, a die-casting method for T&N Technology. The pattern across forty years is consistent and is the true story the failed claim was standing in front of: Granger is where inventors live, not where invention is claimed. A high-income professional suburb beside a research university and a diagnostics industry produces exactly this — residence lines on other firms' patents, and no founding myth of its own. (The search carries a hazard worth printing: "Granger" is also a surname, and the patent indexes are full of unrelated Granger inventors elsewhere; residence in Granger, Indiana 46530 is the only test applied above.)
