IBM has counter claims against SCOX that can become active once Zombie SCOX is released from bankruptcy.
Theoretically, they already are active. The case was re-opened at the request of The SCO Group on June 14, 2013 (docket # 1115).
According to docket # 1179, IBM is still asserting the following counterclaims: Count I (breach of contract), Lanham Act (Count II), Count III (unfair competition), Count IV (intentional interference with prospective economic relations ), Count V (violation of the New York State Unfair and Deceptive Trade Practices Act), Count VI (breach of GPL), Count VII (promissory estoppel), and Count VIII (copyright infringement).
At present, IBM is asking for summary judgment on Count VIII (copyright infringement).
All that is needed now is for Hizzonor Judge Nuffer to get off his ass and make the case go forward.
