The EDS court case has cost Sky £7m in the three months ending 30 September 2007, according to the broadcaster's latest financial results.
The broadcaster expects to incur additional costs of around £16m during this financial year.
EDS, which provided services to the Group as part of its investment in CRM systems software and infrastructure, is being sued by Sky for allegedly misrepresenting its capabilities when bidding in 1999 for the £48m contract.
Sky is claiming £709m for lost benefits because of late delivery.
EDS has denied the claim and said that in its own third quarter financial results that contract signings for the quarter represented the best third quarter signings performance in five years.
