Lucasfilm filed a lawsuit last week against New York Jedi and Lightsaber Academy, which teach classes on how to engage in Jedi battles, alleging that the businesses’ use of the words “Jedi” and “lightsaber” along with a logo of the Jedi Order are in violation of intellectual property laws.
The difference between this lawsuit and the one against Axanar is that Disney apparently sent multiple cease-and-desist letters. Paramount and CBS didn't do that with the Star Trek fans at Axanar.
