Nah. I'm gonna continue to call that shit velcro, even if it's not by Velcro. It's up to the other companies not on infringe on trademark, and on Velcro to protect it. None of it is on me. Ya'll victims of your own success, I don't feel so bad.
It's generally one of the primary grounds for cancellation of a trademark. E.g., in the US:
Lanham Act sec. 14 (15 USC § 1064(c)) said:
A petition to cancel a registration of a mark, stating the grounds relied upon, may, upon payment of the prescribed fee, be filed as follows: . . . at any time if the registered mark becomes the generic name for the goods or services, or a portion thereof, for which it is registered. . .
I'm actually a little surprised that Jet Ski and Rollerblade were ever granted in the first place given that they are effectively combinations of common words that serve as a descriptor of the product. I can at least feel some degree of sympathy for Velcro but I just want to point and laugh at those two.
I was helping someone repair something that the velcro came off of recently by using some old scrap. I asked them to hand me a piece and they gave me the wrong side so I asked for the other one. They got confused and so I had to explain that each side of velcro is different and that's how they grab each other. I used the term "hook and loop" during this and they thought I was making it up.
In what kind of world do those people mad at this in the comment section live in?
I think some have started to forget how to consume media or just plain got to wrong idea to begin with by getting their world news out of comedians and YouTubers, so in their eyes this is as serious a public announcement as they get.
That said, a poor attempt at a viral video isn't going to stop anyone from calling non-Velcro things as Velcro. But then again, consumers are under zero obligation to give an crap anyhow. Its not our job to protect their trademark. Maybe they can actually do something against retailers who use the wrong terminology, policing that would be a bitch though.
