Nortel (NT) sues Vonage (VG)

Vonage (NYSE: VG) must has 100 people in its general counsel's office. The company only has 1,600 people.

The comment may be fanciful, but the Vonage patent problems are not. Nortel (NYSE: NT) has now become one of a long list of companies to sue the VoIP company, which went public at $17. Vonage shares now trade for $2.

The Wall Street Journal writes (subscription required) that "the patents relate to technology that forms the basis of Internet-based voice service, as well as features such as 911 and 411 calling and click to call, according to Nortel spokesman Mohammed Nakhooda."

Investors in Vonage had hoped that the company's intellectual property problems were behind it. The company has already lost legal actions to several large U.S. telecom companies, including Verizon (NYSE: VZ).

And, Nortel needs to be careful. The Canadian company may be better off with a quick settlement than with a lengthy lawsuit. Vonage is already crippled by lost legal battles and negative cash-flow. On its last balance sheet, the company had $350 million in cash and investments and $275 million in long-term.debt. Payables were $332 million.

Nortel could win the suit and end up with nothing to show for it.
