|FASA Corporation]] published the first ''BattleTech'' game set in 1984, and throughout the '80s and '90s released a wide range of supplemental books and materials for the series. FASA ceased producing ''BattleTech'' in 2001 and sold the [[w:intellectual property|intellectual property]] (IP) to [[WizKids]]. [[ FanPro]] , who had previously held the license for German '' BattleTech' ' products, licensed the rights from WizKids and continued to release sourcebooks and supplements under the '' Classic Battletech'' moniker. IP holder WizKids was purchased by [[ Topps]] in 2003, and terminated as a brand in 2008; ever since, the IP to ' 'BattleTech'' ( and others) are held directly by Topps.
Between 2002 and 2008, the IP was split and a new BattleTech game line called '''[[MechWarrior: Dark Age]]'' ' was produced which employed the substantially different [[Clix]] rules . The original board game line was re-branded '''[[Classic BattleTech]]''', but the "Classic" prefix was dropped again from new products after the Dark Age line was discontinued in 2008. It remains in use to some extent, often to differentiate from the Clix game, and is now synonymous with the BattleTech board game.
In June 2007, FanPro's license ran out and [[Catalyst Game Labs]] (a subsidiary of [[InMediaRes]] Productions, LLC) acquired the license to Classic BattleTech in their stead. Catalyst also retained many of the staff members who previously worked for FanPro.<ref>[http://catalystgamelabs.com/2007/05/17/inmediares-productions-llc-forms-imprint-catalyst-game-labs Catalyst Game Labs » Blog Archive » INMEDIARES PRODUCTIONS, LLC, FORMS IMPRINT: CATALYST GAME LABS<!-- Bot generated title -->]</ref><br />
