Trademarks are a rather tricky issue. Most times, companies won't care if the name is used for something else as long as it is for something that is completely unrelated and it doesn't harm the name and/or owner of the trademarked item. No one would ever confuse an Evolution X paintball item with an Evolution X Xbox item.
Besides, many other things are named Evolution X. I just did a Google search and found Evolution X vitamins, population calculators, car products, X-Men products, etc. The name "Evolution X" is somewhat common enough where many products can use the name. Who knows who was the original user of the name? Maybe they should sue the paintball company for stealing the name? The fact is that no one really cares if others in non-related fields use it as long as it doesn't give their own product a bad name.
