What are you talking about you are the one who brought trademarks in to try and prove that MS own the IP, I just countered your trademark links that only applied to videogames with links to the trademarks that cover everything else that the IP is used for.
As for why it's not on their website Mechwarrior the rights (including the trademark for Mechwarrior when used for a video game) to videogames bassed on the IP are owned by Microsoft so they only need to expressly mention MS as the product is a videogame. All other trademarks for the mechs, universe etc are covered by the "All other trade-marks are the property of their respective owners; ® or ™ as indicated" part.
And the board game (the souce of the IP) is currently being licenced to InMediaRes Productions subsidiary Catalyst Game Labs, http://www.catalystgamelabs.com/2008/06/27/catalyst-game-labs-bring-classic-battletech-shadowrun-and-mechwarrior-novels-back-to-bookstores/, http://www.catalystgamelabs.com/battletech/
"Classic BattleTech, BattleTech, BattleMech, ‘Mech, and MechWarrior are registered trademarks and/or trademarks of The Topps Company, Inc. in the United States and/or other countries."
Notice that it's not just the MechWarrior name that is owned by Topps.
Also I already pointed out that I was mistaken when I suggested they just call it Battletech it turns out MS own the videogame rights to everything to do with the Battletech IP not just Mechwarrior.
Anything else?
