Islandia, New York-based CA amended its existing misappropriation of trade secret and unfair competition complaint against Rocket with the addition of copyright infringement claims and the $200m price tag.

According to CA, Newton, Massachusetts-based Rocket knowingly and intentionally stole from CA the source code and development environment used to create Rocket’s software tools for IBM’s DB2 database management software.

CA has accused Rocket of obtaining the source code by hiring programmers previously employed by CA or Platinum Technologies, which CA acquired in 1999, and deliberately using it to create the company’s own DB2 management technologies.

Rocket has not responded to CA’s allegations. The company runs a diverse product portfolio including business intelligence security, network and storage management, developer and mobile tools, and has expanded rapidly in the last 12 months via an acquisition spree.

In July 2006 the company acquired mainframe systems software specialist Mainstar before snapping up three database management products from Telcordia in September.

In April this year the company finally landed Seagull Software, the host integration and modernization vendor, four months after its initial bid. More recently the company acquired performance management firm CorVu for $20m in May.
