Indian engineering firm Larsen & Toubro, IT services firm Tech Mahindra diversified Spice Group are among the firms that have already announced their interest.
Other firms said to be interested include IBM, HP and CSC.
Satyam has a good reputation for service delivery, it has a large number of highly skilled workers and boasts an impressive list of customers.
But bidders could be limited as a result of the company's involvement in a $1bn accounting fraud. Former chairman B. Ramalinga Raju admitted he had falsely reported the company's results. This left the company short of cash and its customers short of confidence.
