That berries n' cream is so good - sublet to other manufacturers
Wish all my throws were G2 berries n cream
. Kidding... Sort of...
There seem to be implied gentleman's agreements not to bite each other's company-specific colourways too badly (let's face it, clear with some sort of blue splash is an example of something any company could have!) but you can't actually trademark a colourway.
That said, if a company wanted to do "berries n' cream" it'd probably be considered good form to chat with Jake. And definitely if they wanted to use that name.
