SAN FRANCISCO — Kobre & Kim is moving forward with what could be a groundbreaking international lawsuit alleging systemic overcharging of patent renewal fees by a company called CPA Global, after securing a financing deal with Bentham IMF to defray the risks of a loss.

Michael Ng, an attorney at Kobre & Kim in San Francisco, will be the U.S. lead for the planned lawsuit. Ng said Friday the firm is completing its investigation and plans to file “in relatively short order” a collective action in Jersey, the British Channel island where CPA Global is based.
