Huawei wins telecoms patent case against ZTE
A court ruling in Germany has given the telecoms equipment firm an important win in its fight with rival over LTE mobile technology

The patents dispute between the mainland's two largest telecommunications equipment makers has heated up after Huawei Technologies won an injunction from a court in Germany against ZTE, which is now barred from selling its 4G-ready base stations in that market.

ZTE said it was "confident the product involved in the lawsuit doesn't infringe Huawei's patent rights", adding that the court's decision would not affect its business operations worldwide.
Huawei, which is privately held, brought lawsuits in Germany, France and Hungary against ZTE in April 2011, mainly for alleged infringements of its rights over a patent on "key derivation function", which represents a "standard-essential patent" for the 4G mobile technology called long term evolution (LTE).
ZTE filed a countersuit in mainland China later that month, alleging that Huawei had violated ZTE's 4G LTE patents and should pay unspecified compensation.
An intellectual property analyst, Florian Mueller, described Huawei's court victory as a "hole in one" against its rival.
In his online Foss Patents report, Mueller said the Mannheim court "ordered ZTE to cease and desist" from selling 4G LTE-mode base stations to telecommunications network operators. It can only sell 3G or 2G-mode base stations in Germany.
