[[FASA|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,
Topps holds the IP to ''BattleTech'' ( among others).
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 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 />
