Verizon’s lawsuit against Vonage is the VoIP version of showdown at Ok Corral!
The weary entrepreneurs have gone from fighting the regulatory morass to fighting the patent morass. The ability of Verizon et al to play the dimensions of uncertainty associated with patents makes one nostalgic for the ability of Verizon et al to play the dimensions of uncertainty associated with the regulatory pronouncements of the FCC. Anyone not attracting a patent lawsuit should feel a bit embarrassed. All the companies with some claim to success will get their turn before Verizon exhausts its legal budget.
Lost among the legal theories, predictions of Vonage’s demise, and the wishful claims Vonage’s troubles are unique is the fact that the future of the VoIP industry depends on challenging vague, generic, overly broad patents. The hope for low cost communications, cool applications, and connected devices has been lost in a patent system gone wild, where companies file patents, just as telemarketer dial for dollars.
The birth of the VoIP industry happens to coincide with the greenlight on “method patents” aka software patents. The framing of Verizon’s patents as “technology innovations” reflects a press release version of reality. Verizon’s patents address methods of communication between network elements.
They would have been unpatentable as little more than mathematical algorithms until lawsuits overruled the patent office’s distaste for method patents in 1999. Efforts to establish the quality of method patents represents a particular challenge, because applying companies pursue an application fatigue strategy. Companies make a long list of broad claims and await rejection. They use information in the rejection to refine the claims and repeat the process.
Method patents remain in dispute and Congress appears ready to pursue reform, but the VoIP industry seems unlikely to survive long enough to benefit from a cure. The need for a better means of vetting software patents motivated IBM, Microsoft, GE and others to assembled a public peer review process in conjunction with the patent office, but other priorities and a slow start mean the project does not offer a near term solution for
the VoIP industry.
Participants in the VoIP industry will need to quit cowering in the corner and initiate their own efforts to move the patent process back toward meritocracy. The three surviving patents Verizon claims Vonage infringes represent a good place to start. They look like the prototypical “garbage patent” clogging the system.
Five years of graduate engineering education, five years at Bell Labs, and five years working on VoIP startups should equip me to appreciate the innovation content of Verizon patents. In fact, as the Project Director for Vocaltec Communications, I was the senior technical person responsible for implementing Verizon’s first VoIP pilot in 1997. Reading and re-reading the patents leaves me at a loss as to their innovation content.
Extensive scrutiny of patent claims represents the only way forward. The Internet that sparked several million articles associated with Wikipedia can cope with due diligence on 2200 VoIP patents. AT&T successfully prosecuted 600 patent infringement cases between 1876 and the expiration of the telephone patent in 1891. This time around there is no patent on the basic innovation underlying VoIP.
Verizon can’t make the Internet go away with a patent lawsuit. Vonage’s poor showing in court does not prove patents on implementation issues and features will ultimately sink the VoIP industry. Verizon’s success reflect genius in applying for and defending patents, not genius in innovations protected by patents.
I don’t begrudge Verizon’s right to pursue all legal means to preserve the status quo, but three generic and ambiguous patents seem a thin reed for a $90 billion company. If patent disputes ultimately undermine the VoIP industry, it will owe to the self-inflicted wounds of inertia, not patents. The industry need not sit idle for the next 15 years waiting for patents to expire. Take a look and judge for yourself.
