UK court ruling gives guidance on tech patent rights

Britain's High Court ruled Wednesday that it can decide what mobile phone makers should pay to use patented technology that is essential to make mobile networks function.

In a case that helps clarify how patents are handled in the telecoms industry, Judge Colin Birss ruled that the court can determine what a fair, reasonable and non-discriminatory rate is for licensing agreements. Such rates cover the use of patented technologies that have become the standard on which global mobile phone networks are based.

The case involved Unwired Planet International, a U.S.-based patent holder, and China-based Huawei Technologies Co.

"This is a ground-breaking judgment," said Pat Treacy, a partner at the London law firm Bristows, which was not involved in the latter part of the litigation. "It gives guidance to companies about how they should set the terms of these licenses."

The decision is important because it clarifies the relationship between the companies that make mobile phones and those who own the patents for the technology that makes it possible for those handsets to communicate with each other.

Early in the development of mobile phones, the industry recognized it would have to adopt unified standards to promote widespread use of the technology. But this had the potential to give those who developed the preferred technology an extremely powerful position that could have choked off future development.

Standard-setting organizations tried to level the playing field by requiring patent owners to license their technology under what were called fair, reasonable and non-discriminatory terms, or FRAND.

But that raised the question of what FRAND terms would be, with patent holders and manufacturers choosing different definitions. Until now, the courts have offered little guidance but the decision offers a roadmap for how the two sides should work out licensing agreements.
