SAP SE has been hit with a lawsuit from a former joint venture partner claiming the German enterprise software giant stole trade secrets and copyrights to create its own competing product, and then coerced customers of its enterprise resource planning apps to purchase it.

According to the 35-page complaint filed Tuesday by enterprise data analytics and warehousing company Teradata Inc., the market for SAP’s competing HANA product generated $2 billion in revenue as of 2016. Teradata alleges SAP’s actions violated state and federal trade secret laws, infringed its copyrighted database software, and violated federal antitrust claims by unlawful tying the sale of the two SAP products and monopolizing the market for enterprise data analytics and warehousing services for customers using its core apps. Teradata is asking for treble damages on its antitrust claims.
