The Fine Bros from Youtube are now attempting to copyright "reaction videos" (something that has existed before they joined youtube) and are claiming that other reaction videos are infringing on their intellectual property

This is more like Sony trying to monopolize the use of the word 'speakers'.

It's actually very much like my COM2US example, which is why I included it. When they began enforcing that trademark, it caused quite a stir in developer circles. A large number of tower defense games followed the format "_____ : Tower Defense." It was the name that had been given to a genre of games, and it was being used as a descriptor.

99% of trademark enforcement is just about being a bully. You send a very formal and scary sounding letter and you hope that the recipient complies. Lawsuits cost a ton of money. Whenever you make a legal demand, regardless of the merits, your hope is that the other party simply rolls over and complies. But you don't have to. I've received a few absurd legal threats in my time, and you know what I do with them? I give them the contact information of my attorneys and I never hear from them again. Most people are clueless when it comes to IP law, and very few are foolish enough to make a go of intimidating an expert in the field.

'Geared' isn't the commonly used word to describe a type of video or game.

"Gear" is in the top 5000 most commonly used words. It might not seem common in this context, but consider it in the context of SEO. More than one developer friend has told me what a mistake it was to use such a common name. My aim was to provide insight into the reasons why someone would trademark their brand, regardless of how common the word is. The assumption in this thread is that the fine bros are abusing the system. At present, that assumption is unfounded. Everything they have done so far is standard practice (with the exception, maybe, of creating one of the worst marketing videos ever to sell the idea). Until they abuse their trademark, there is nothing to be outraged about.
