Mobile payments firm Upaid has requested depositions from Satyam executives regarding last week's aborted attempt by Satyam to buy up companies related to its chairman, Ramalinga Raju. Upaid claims this was an attempt to siphon cash out of the business in advance of a US Federal Court jury trial scheduled for June 2009, in which Upaid is seeking up to $1 billion in damages for fraud, forgery and breach of contract by the Indian IT giant.
