In other words, VALVE can copy DOTA at will, but what has been copyrighted by Blizzard in DOTA cannot be copied. That's why Blue Cat became an uncle, Brewmaster became a lemur, vanity became a mouth but no eyes (DOTA has eyes but no mouth), Nei Lu Bianchi Hashshashin became a Knicks Hashshashin, and the Q of the Moon Festival was renamed the call of stars instead of the fall of stars.
In terms of names. The court acknowledged that the copyright of "Ancient Defense" belongs to fist. However, VALVE cunningly exploited loopholes in the law, claiming that its DOTA is a new word, not an abbreviation. So, Bilong lost his temper and scolded three streets in Icefrog on the Internet ... because the copyright law only protects the full name and abbreviation of your registered name, and does not include the provision that if someone uses your abbreviation to make new words, he will ask for copyright. So the court approved VALVE to use the word DOTA and gave it copyright. However, Dota can only be written as DOTA, or DOTA. It doesn't mean anything, shorthand or anything. DotA or infringement.
