I wrote a book which I released in April, 2015. I've just discovered there's a pen/paper fantasy game similar to dungeons and dragons with the same name that was a kickstarter back in May 2014, which was last updated April 2015 (there was about a year gap between updates.)
My question is, although I didn't know it existed as my internet searches yielded nothing, I can find no listing of trademark or copyright or anything of the like, could I potentially be infringing copyright?
They are similar is two regards other than the same name, that is the logo is slightly similar, and both are in the fantasy genre, although the settings, worlds, character, etc... are all wildly different.
Not sure if I'm allowed to post links but can do so for someone to check if needed.
