I understand that it was the Stoeger company that trademarked the name "9mm Luger" in America after WWI. Most countries call it the 9mm Parabellum (from the Latin: "Sic pacem, parabellum." "If you want peace, prepare for war."). I saw some results of testing various 9mm Parabellum loads by H.P. White laboratories after WWII. The current Winchester 9mm NATO load sometimes seen in stores is about the same as the German WWI/WWII rounds. The 9mm Parabellum is now 110 years old!
