To evaluate the IPR leadership in wireless communications, the US patents that are related to the key wireless standards are analyzed. The wireless patens are grouped by mobile wireless communications (4G LTE) related patents and fixed wireless communications (WLAN, WPAN, NFC) related patents. Patent disclosures in claims and detail description for each patent are analyzed as to whether the contents are within the scope of key standard specifications (3GPP, IEEE, ISO, NFC Forum). Top 20 patent holders for each group are then selected to rank the combined IPR shares. For details about the analysis, please refer “Wireless Patents for Standards & Applications 1Q 2015” (http://www.slideshare.net/alexglee/wireless-patents-for-standards-applications-1q-2015).
For the mobile wireless communications IPR, LG Electronics is the leader followed by Samsung Electronics, Qualcomm, Google, Ericsson, Nokia, Apple, InterDigital, BlackBerry and Panasonic. For the fixed wireless communications IPR, Sony is the leader followed by Intel, Marvell, Samsung Electronics, Qualcomm, Broadcom, Cisco, NXP, Philips and Texas Instruments. Combining the mobile and fixed wireless communications IPR, Samsung Electronics is the leader followed by LG Electronics, Qualcomm, Intel, Sony, Nokia, Google, Ericsson, Marvell and InterDigital.
The combined IPR shares for the top 20 IPR holder’s countries based on the location of headquarter show that the U.S. holds IPR leadership in patents for the key wireless standards.
