Trademark question
Location: Washington
I'm developing a video game and looking into trademarking its name in the U.S. I'll use completely fake names because I don't want to identify either property.
My proposed mark is essentially “BRAND NAME” two words with a space.
I found an active registration where the beginning of the mark is essentially “BRANDNAME” the same two words combined without a space followed by several additional words forming a much longer title, something like “BRANDNAME Of the Forgotten Kingdom”
The existing registration is a stylized/design mark rather than a standard-character word mark and covers tabletop/RPG/card/board-game products in Class 028.
I'm looking to register “BRAND NAME” as a standard-character mark for a downloadable PC/video game in Class 009.
I understand different classes don't automatically eliminate likelihood-of-confusion issues. I'm wondering how much weight is generally given to:
• the existing mark having several additional words
• BRANDNAME vs. BRAND NAME
• their mark being stylized rather than standard characters
• tabletop games vs. downloadable video-game software
Would an existing registration like this commonly present a likelihood-of-confusion problem, or are these differences potentially meaningful?
I'm planning to consult a trademark attorney before filing; I'm mainly interested in understanding how these factors are generally evaluated.
