Microsoft has suspicions that an ex-employee retained strategic data after he left the firm for a position at rival Salesforce.com.
In an amended court motion, filed with a Washington State Superior Court on Thursday, Microsoft alleged that Matt Miszewski lied about retaining over 600MB of proprietary information after he left the company, according to reports.
"[The data] would be highly valuable to Microsoft's competitors, including Salesforce.com," Microsoft said in the motion, according to Computerworld, "both in terms of capitalizing on Microsoft's efforts to prepare these materials, as well as revealing in detail Microsoft's own competitive strategies."
Upon his resignation on 31 December Miszewski told Microsoft he had taken purely personal items with him, Microsoft said in the motion.
But under subsequent rules of discovery Miszewski produced 600MB data from his computer, comprising over 900 separate files running to a combined total of 25,000 pages, Microsoft said. Documents included playbooks and business plans for Microsoft's 2011 cloud computing products and services and government group strategies.
"Miszewski was — and is — uniquely and intimately familiar with some [of] Microsoft's most confidential sales, marketing and production information for its CRM and cloud computing solutions," Microsoft's complaint stated.
Microsoft, Salesforce.com and Sage all compete with one another in the CRM sector.
By accepting a job at Salesforce.com, Microsoft said Miszewski placed the Azure cloud platform and the Dynamics CRM product line in danger.
The revised motion is an attempt by Microsoft to transform a temporary restraining order from January into a longer term one, barring Miszewski from taking up his position as a senior vice president with Salesforce.com.
At Microsoft, Miszewski was a general manager of Worldwide Government. Prior to Microsoft he worked as the chief information officer for the state of Wisconsin.
