The one-time glamour couple of the hedge-fund industry, Elena Ambrosiadou and Martin Coward, renew court hostilities on Tuesday in a bitter row over intellectual property.
Mr Coward is taking Ms Ambrosiadou's hedge fund, IKOS, to the High Court arguing that the highly complicated software that has proved so successful for the company belongs to him. The pair met at Cambridge University in the late 1970s, where Mr Coward was studying for a mathematics PhD, the research for which is said to have formed the basis of the "quant" trading model used by IKOS. This is one of about 60 ongoing court cases stemming from the couple's messy divorce. They co-founded IKOS in the early 1990s, but Mr Coward suddenly quit in 2009.
