Huawei claims lead in LTE patents
As Huawei continues to put pressure on rivals for LTE contracts, it is also claiming to lead its rivals in LTE patents.
The Chinese vendor said ETSI has confirmed its award of 147 LTE patents, which is claims cross several key LTE subsectors such as physical-layer air interface, radio resource management and connection management. In all, its patents represent 12 percent of the total existing 1,272 LTE patents assigned by ETSI as of August 2009, Huawei said.
Recently, using 60 LTE base stations from Huawei, T- Mobile Austria claims it has conducted the largest multi-user trial of LTE under real-life conditions. Last month, Vodafone Germany has announced it will conduct independent trials of the technology using equipment from Huawei starting this summer.

I'd like give a guideline in understanding recent claims for LTE patents:
1. Nationality of patents: most of Huawei's 147 patents are in China's national stage, which means Huawei's LTE patents IPR will be effective only for Chinese market. It is possible that Huawei can apply patent to USPTO claiming the Chinese patent applications for US market and to EPO for EU market. In this case, the patent filing dates will be the most important factor for claiming priority.
2. Number of patents: the total existing 1,272 LTE patents assigned by ETSI as of August 2009, do not represent all the LTE patents. For example, recent LTE patent analysis by TechIPm found that Motorola is now holding more that 100 LTE related patent applications which were not in the ETSI list.
3. Quality of patents: to have some market values, a LTE patent should be an essential patent, which means the content should describe the LTE standards. Recent LTE patent analysis by TechIPm showed that less than 50% of the LTE patents claimed by most LTE patents holders could be potential essential patent candidates.
