Remarkable trademark attempts

Just because it’s Friday: 5 remarkable trademark attempts:

1. Twitter lost the word “tweet” to a third-party developer, as it was too late filing a trademark application.
2. The New England Patriots football team were not able to register “19-0”, after a crushing 19-0 Super Bowl victory. The application was refused.
3. US wholesale chain Walmart tried to claim the smiley face. Again, denied. Of course. We all know Forrest Gump invented it.
4. Harley Davidson tried to trademark the sound of its motorcycle engine.
5. Boise State University trademarked its blue football field. In response, other schools started dyeing their pitches in other ridiculous colours.

Have a nice weekend!
