Hewlett Packard said on Monday it would continue legal proceedings to seek up to $4 billion in damages from British billionaire Mike Lynch’s estate in the UK.

The U.S. company had been seeking compensation over its acquisition of British tech firm Autonomy amid claims of fraud masterminded by its co-founder Mike Lynch to inflate the company’s value.

Lynch, who died in August when his yacht sank off the coast of Sicily, had denied any wrongdoings.

“It is HPE’s intention to follow the proceedings through to their conclusion,” the company said in an emailed statement to Reuters.
