Chinese telecom device maker Huawei invested USD9.2 billion in research and development in 2015, accounting for 15% of the total annual income of the company.

The World Intellectual Property Organization says that by the end of 2015, Huawei had been a leading patent applier for two consecutive years, with 3,898 accumulated patent cooperation treaties. By December 31, 2015, Huawei had gained 50,377 patents around the world. Those patents are related to LTE, operating systems, and user interfaces, which are very important for the development of smartphones.

As a leading supplier and patent owner of information and communications technology solutions and smart devices, Huawei put great efforts in research and development. Its investments were mainly used to develop new technologies and products and improve mobile communication services. Over recent years, Huawei has enhanced its R&D investment and generated a large number of high-value patents.

Henry Liu, head of Huawei Device in Sri Lanka, said that with continuous innovation and development, Huawei keeps on improving new technologies, which is an important factor for Huawei's success in Sri Lanka and the world. They will continue to invest in R&D business and focus on providing high-quality services to customers.

WIPO tracks applications filed under the Patent Cooperation Treaty, an agreement that gives a filer patent protection in 148 countries with a single application.
