For eight years the arts collective Newmindspace had been staging free lightsaber battles, and in December they set a world record with 9,951 "combatants" simultaneously participating in San Francisco, Los Angeles, San Diego and Seattle. But then in January they received a letter from the copyright attorneys for the Star Wars franchise. "We immediately stopped using the words 'lightsaber,' 'Jedi,' 'Sith' and 'The Force,' " the group's co-founder told the technology blog of the San Jose Mercury News, saying they've still been "aggressively pursued" for the last three months. '''In March we received further communication stating 'The Light Battle Tour' and 'light sword' were still too close to their trademarks, and we moved to settle the dispute to avoid legal action." Their new solution involves referring to the weapons as "catblades", and they've re-branded their upcoming series of events (which begins on April 30 in San Jose) as the "Cats in Space Tour".
