Looks like the giant woke up. As previously reported, Spark Unlimited launched a lawsuit against Activision, alleging that Activisionfailed to pay promised royalties for the first title developed under that deal (the console edition of Call of Duty Finest Hour), and took Spark's proposals for a sequel and gave them to its own developers.. Now, Activision has filed a counter-suit against Spark, allegingfraud, breach of contract, trade secret misappropriation, trademark infringement, false designation of origin, and false advertising. In a lengthy statement of claim, Activision refutes virtually everything alleged by Spark, and paints an interesting alternative perspective of Spark's claims. Activision also argues that Spark's refusal to return Activision development kits, mixed with the fact that Spark is generating new content for Atari, may result in Atari unwittingly violating Activision's intellectual property. Ultimately, Activision has requested that damages be calculated through a full trial, which indicates a potentially lengthy (and potentially difficult for Spark to finance) legal battle between the two companies.
