In This Article:

(Bloomberg) -- A London-based investment firm accused a hedge fund of misusing trade secrets to set up its own lucrative fund, according to allegations at a UK trial.

Illiquidx Ltd. sued the hedge fund Altana Wealth Ltd. following a failed attempt to set up a joint venture in 2019. The relationship broke down within months and Altana allegedly used the confidential information shared during the short-lived partnership to set up a sanctions-compliant fund to invest in Venezuela’s sovereign debt, Illiquidx says in documents prepared for the trial that started this month.

The dispute, playing out in London’s High Court, shows just how much could be at stake for those trading in the debt of Venezuela’s defaulted notes. Having jumped in value last year, some holders are hoping that further gains will mint lucrative profits. The scale of the potential returns make such court cases worth fighting.

“You and I share twice the pie” without Illiquidx’s further involvement, Altana’s founder Lee Robinson is alleged to have told Brevent Advisory Ltd.’s director Steffen Kastner in an email, according to lawyers for Illiquidx. Robinson and Kastner, who introduced the two businesses, are also named as defendants in the case.

The email was sent in the context of Illiquidx walking away from the joint venture, Robinson countered during cross examination from Illiquidx’s lawyer during the trial.

Altana, Brevent, Robinson and Kastner denied all allegations and are contesting the claim. Illiquidx never provided information “beyond the general idea to invest in distressed Venezuelan debt,” and that was in part why the joint venture fell apart, Altana’s lawyers said.

“Nothing Illiquidx claims to have provided amounts to any sort of confidential ‘special insight’ or trade secret,” the lawyers said. “Indeed substantially all of the business opportunity and detail now relied on was trite” or public knowledge.

The trial is among a rising number of bitterly fought legal disputes around fiercely guarded business secrets in the financial industry. Courts in London have often hosted such cases as companies go to extreme lengths to protect against poaching and guarding valuable information.

The most prominent cases in the past year include rival quant funds trading accusations over a “special” trader with confidential information and BGC Group’s suit against an options broker over “extremely valuable” confidential knowledge about clients and trades.
