Just as no one is suggesting Rust the game and Rust the programming language are violating each others mark...this Trine doesn't violate other "Trine" marks. Trademark is protection for a specific mark in a specific industry, and not the exclusive right to use a word for any purpose.
Made up words are sometimes more strongly defensible... Thus "Google" would not be usable legally in the US for any product. But "googol" might be for products that don't overlap with products made by Google. But, Trine is not a made up word.
