The judge in the case gave the jury a directed order to basically find in favor of the Winghouse, which they did. The argument from the Winghouse was that they can't be stealing a trademark from Hooters because the clothes are functional and functional clothes can't be protected that way. In case you're wondering, the function has something to do with boners.
Hooters tried to appeal the decision and lost once again, proving the legal system will not stand for anyone trying to hold an illegal monopoly on reducing their wait staff to boobies that can serve drinks.
Honorable Mention: McJob
In 2001, Merriam-Webster added "McJob" to their dictionary, defining it as "a low-paying job that requires little skill and provides little opportunity for advancement." The CEO of McDonald's rattled off a bitchy letter, oblivious to the fact people had been using McJob to mean exactly what the dictionary said it meant for well over a decade.
When simply whining like children didn't work, it was later stated in a veiled, sad threat that McJOBS is trademarked and is the name of the program McDonald's uses to train mentally and physically disabled employees. So they were apparently preparing a claim that the dictionary violated the trademark by including the term, demonstrating McDonalds' complete lack of understanding of what a dictionary is.
For once, the McDonald's legal team showed some restraint and the lawsuit at the heart of their veiled threats never came to pass. Instead, McDonald's has gone on a publicity campaign to try to convince the whole world to stop acting like jobs at McDonald's aren't awesome.
They've also started a petition again the Oxford-English Dictionary, hoping to convince it to remove McJob and its similar definition ("an unstimulating low-paid job with few prospects").
McDonald's claims that definition is false and has evidence that 90 percent of its employees believe they receive valuable training that will be of benefit for the future, not mentioning how many of them believe that because they have resigned themselves to working at McDonald's for the rest of their lives.
