… just look at how the tennis star Lleyton Hewitt has trademarked his… salute. Yes, I'm not kidding: apparently you should be aware that next time you hit a smash, your exultant routine doesn't incloude anything that vaguely resembles the Australian player way to rejoice.
When it rains, it pours: it appears that the celebration gesture, which by the way dates back to the Vikings when no stupid patent law was even to be imagined, was actually already trademarked by Niclas Kroon, another tennis player who accidentally forgot to renew the registration. Hewitt agents noticed the brainfart and quickly filed a new record, with an action that closely resembles a Viking foray.
History repeating itself, apparently.
