During November of 2010, Archie Comic Publications filed suit against Ken Penders, a former independent contractor who had worked on the Sonic comics.  Sega had licensed Archie Comic Publications the rights to create Sonic comic books, among other things, in 1992.  Between 1993 and 2005, Ken Penders created content for these comic books, including scripts and artwork, as an independent contractor.   In 2009, Penders began registering copyrights for the work he had done for Archie Comics and sent Archie Comics a letter in 2010 alleging that they were infringing upon his copyrights.  Since Penders was threatening legal action, Archie Comics decided to bring suit against Penders seeking the cancellation of Penders' copyright registrations, declaratory judgment, and remedies for breach of contract and tortious interference.  Penders has since filed suit against Sega and Electronic Arts.
