In mid-December of 2012, I received a notice from Amazon that they had suspended the sales of my e-book, Spots the Space Marine, in response to a complaint from Games Workshop that I was infringing on their trademark on the term "space marine." Looking up the relevant trademark information in the US, UK and European databases, I discovered that in no country did GW have a trademark on any class related to fiction. I discussed this with Amazon, which told me to talk with Games Workshop. Over a period extended by the frequent absences due to the holidays, I had that discussion and could not reach an agreement with GW.
