Vonage: patent case could force bankruptcy

Vonage's SEC regulatory filing has warned of potential consequences of continued litigation

The ongoing patent-infringement battle between VoIP provider Vonage and US communications giant Verizon could result in Vonage facing bankruptcy, a filing to the US Securities and Exchange Commission yesterday warned.

The regulatory filing detailed other possible risks from the ongoing litigation that could materially affect the company's business, including a possible interruption of service which could affect results and impact on the continued viability of the company.
