Abstract

Abstract: As one of the key technologies of the new generation of high mobile wireless communication, rateless codes have drawn attention of countries all over the world. From the patents, we investigated the development trend, the patent source and distribution, main organizations, research hotspots and core patents by using analysis tools including the PatSnap database, Innography and the Insights. The results show that the quantities of patent applications has generally increased since 2006. China, American and Korea ranked the top 3 of the number of patents. Top three organizations for patents applications were Qualcomm Incorporated, Thomson Licensing and Huawei Technologies Co., Ltd. The research hotspots mainly focus on arrangements for detecting or preventing errors in the information received(H04L1) and coding, decoding or code conversion, for error detection or error correction et al.(H03M13).
