The USPTO may have a differing opinion.

Just because a word is a common dictionary word doesn't mean it can't be trademarked with limited use. For example, you can't launch a new computer and name it Apples. However you can launch a new type of lipstick called Apples (assuming it's not trademarked in that context already).

If the original trademark owner can show that there's the potential for confusion among consumers, that the products are competitive, Infinit may very well prevail. Dropbox's lawyers didn't do a great job at due diligence here.

I like how Infinit responded.
