I still don't really get how this effects weck? What can he really do with that trademark?
If the trademark is granted, it just means weck can't sell tshirts or skateboards with the word "weckingball"on it. He can have the instagram name. It doesn't really change anything. People have made twitter handles and instagram handles and sold them back to trademark owners.
Here's instagram's trade mark policy:
"What if an account is using my registered trademark as it's username?
Trademark violations may involve using a company or business name, logo or other trademark-protected materials in a manner that may mislead or confuse others with regard to its brand or business affiliation.
What is not a violation?
Using another's trademark in a way that has nothing to do with the product or service for which the trademark was granted is not a violation of Instagram's trademark policy. Note that Instagram usernames are provided on a first-come, first-served basis and may not be reserved."
So basically if you have a registered trademark as your Instagram handle first, it's yours just don't pretend you are the actual company. If everyone knows that Kalis owns the weckingball trademark then Weck just being Weck is not a violation.
It's so cold outside and I must be really bored, because I looked into this and I already said I don't care. It's all pretty dumb.
