The breach-of-contract complaint, filed on Sept. 26 with the California Superior Court in San Mateo, alleges that former Siebel Vice President Brett Queener violated a confidentiality agreement.
The complaint claims that Queener participated in a meeting in which proprietary information about Siebel's products was disclosed two days before he left Siebel and after he had agreed to take a job with Salesforce.
Siebel also alleges that Queener, who left Siebel on July 9, helped Salesforce recruit other Siebel executives while still employed by Siebel.
"Queener has breached his obligations under the Proprietary Information Agreement by, among other things, while employed at Siebel Systems, engaging in activities that directly conflicted with his obligations to Siebel Systems, unlawfully inducing Siebel Systems' employees to leave their employment with Siebel Systems, and, on information and belief, unlawfully using and disclosing Siebel Systems' proprietary and confidential information," the complaint states.
Siebel is seeking more than $25,000 in damages and "injunctive relief," according to the complaint. Representatives of Siebel and Salesforce declined to comment on the case, as did Queener.
On Oct. 27, Queener's attorneys filed a motion seeking dismissal of the case, claiming Queener's innocence and calling Siebel's allegations "threadbare," "vague" and "deficient."
"Siebel has failed to identify a single document or piece of confidential information that it alleges Queener improperly used or disclosed to Salesforce.com," the motion states. "Siebel has also failed to identify a single employee that Queener improperly induced to leave Siebel."
A hearing on the case is scheduled for Monday.
