AN IRISH technology firm which successfully sued United Overseas Bank (UOB) and another local firm for infringing its patent is now seeking up to $15 million in damages and lost profits.

Court documents show that in 1999 Main-Line Corporate Holdings invented a computerised system to identify, from a credit card number, the currency involved in a transaction. It then patented the technology in several countries, including Singapore.

Main-Line had hoped to use this technology to make money from foreign currency credit card transactions.
