Cool, bro. I'm Portuguese though. So you missed that.
My story with Wolves is very well known around the forumers. Feel free to research it if you want.
The thing you don't seem to grasp is that Intellectual Property rights are exclusive. The club has a few of them registered (want me to find the registrations?) and, as such, benefit from the exclusivity. The concept of exclusivity includes the right to defend themselves from infringement. Be it from a grandmother knitting beanies at home and selling them to supplement a pension, a one-guy company selling pins near the stadium or a major business profiting (largely) from counterfeiting goods. So long as they are making money off rights, the owners of trademarks have cause to pursue. What is both illegal and immoral is people making money off other people's jobs and work.
Probably, "Football/Casual trends" are not protected whatsoever. So Wolves have nothing to "better watch out". Please clarify what you mean by the expression "football/casual trend", and we may discuss this further.
Just because "nobody died" does not mean the club should not protect itself against these type of actions. It's their right to pursue the people and, let me tell you, they're being awfully nice by starting with cease n' desist letters. While a common practice, they could skip this step and directly sue everyone. Like I said, there are legal provisions which state that actions of infringement, if let to play out over a long period (normally between 5 to 10 years) can then constitute exceptions to the exclusive right. In turn, this dilutes the protection granted by the trademark registrations and decreases the value of said registrations. Ultimately, if the exclusive right is never enforced, it may be cancelled due to becoming generic. While unusual, it is a real danger.
Know what happens when a trademark is cancelled due to being generic? Anyone can use it. Me, you, the club, any other club, company or entity that operates in the market. It is serious. Very serious.
We can continue this, if you want.
Don't worry, it doesn't affect me. I have nothing to prove to anyone regarding my support of Wolves.
