TAIPEI: HTC plans to appeal a US judge's ruling, which stated that the company infringed two of Apple's patents with its data-detection technology.

Asia's second largest smartphone manufacturer is planning to appeal against Internal Trade Commission (ITC) administrative law judge Carl Charneski's verdict.

If the ruling is upheld by an ITC panel, HTC could eventually face restrictions on exporting phones to the US market.

HTC is currently the world's largest manufacturer of phones using Android, the mobile operating system developed by Google.

The patents relate to the data-detection technology used in text and e-mail messages and a data-transmission system.

Recently, the US watchdog has resolved similar patent disputes, with a settlement reached with Apple last month after a complaint was made against Nokia.

Commenting on the ruling, Grace Lei, HTC's general counsel, said: "We are highly confident we have a strong case for the ITC appeals process and are fully prepared to defend ourselves using all means possible.

"We strongly believe we have alternate solutions in place for the issues raised by Apple."

According to figures released last week by Kantar Worldpanel, Android is now the leading smartphone operating system by new sales in eight major markets including Japan, the UK and US.

The study also found that around 75% of Android sales were to customers who did not previously own a smartphone. For Apple's iPhone, this total was 1.4%.
