It’s not patents, it’s trademarks. Kleenex is the best example: Overuse of it as a generic term leads the company to call it “Kleenex brand”. Lego has fought this for years, with the boxes promoting calling them “Lego bricks”, lest all building bricks become generic “Legos”.
Patents expire after 17 years regardless of usage, trademarks can last forever.
