SolarWindow Technologies, Inc. (WNDW): R&D Expense

Annual figures by period end, from SEC filings.

Restated years: each year's figure is from the latest filing that reports it. The company later restated the year ended 2022-08-31 (for example after a spin-off or a discontinued operation), while the year before it was last reported on the old basis. Changes across those points are marked n/c (not comparable), and growth rates are not computed across them.
