Wildcat Intellectual Property Holdings filed suit Thursday against Wizards of the Coast for alleged patent infringements by Wizards’ Magic: The Gathering Online. The subject patent (#6,200,216) covers the implementation of trading card games online:

Wildcat brought a similar suit in July, 2011 against:

  • Sony Online Entertainment
  • Pokemon
  • 4Kids Entertainment
  • Nintendo of America
  • Chaotic USA Entertainment Group
  • Topps Company, Panini America
  • Sony Computer Entertainment America
  • Wizards of The Coast
  • Konami Digital Entertainment
  • Electronic Arts
  • Zynga

A quick web search indicates that the first suit is still active [PDF], though I note that the new one has moved from the Eastern District of Texas to the Northern District.
