I was not aware of this at all. How did Backcountry get the trademark in the first place? It should definitely fail on the first challenge if backcountry is literally a subtype of ski and pre-existed. I know nothing about skis, and all the comments here and in the article made it sound like the furor was all over the generic adjective of 'backcountry' which I took to just be a synonym for 'rustic'.
