I was recently sent a cease-and-desist email from someone associated with CrossFit, Inc, demanding that I remove any references to the word "CrossFit" from my iPhone application's information on the Apple App Store. I complied with their request.
Firstly, is it true that I can't mention the word "CrossFit", which they have trademarked, in ANY way in my application's meta information? Including the title of the app, the description of the app and what it is for (especially, usage of the "CrossFit" trademark in a descriptive fashion, i.e., when describing the app as for "CrossFit style workouts"), or in the "meta" tags for the app (which are meant to help for people searching the store, I believe). They also demanded that I not use any "confusingly similar" words, like "CF", "CrossFitter", or "CrossFitness".
Secondly, there are still apps on the App Store that also make use of the "CrossFit" trademark. I have no idea if CrossFit Inc. is making similar demands from those other developers. What happens if they singled me out, and don't make similar demands of other people, who are ostensibly infringing on the trademark the same way I was?
One of the most dreadful examples is one app, whose title is "myWOD — All-in-One WOD Log for XF Workouts (NOT AFFILIATED WITH CrossFit Inc)". Clearly, they are trying to skirt around the trademark issue by saying they are not affiliated with CrossFit Inc in the title, but get search hits for "CrossFit" because it is present in the title.
