Smartphone Wireless Standards Essential Patents Competitive Index 2Q 2012

Standards essential patent candidates for three key Smartphone wireless technologies are researched: LTE, NFC, and Zigbee. To find the key IPR holders for NFC patents, a keyword search of the USPTO patent data base has been performed.


As to LTE, patent disclosures in claim and detail description for each LTE patent are compared to the final versions of the 3GPP Release 8 technical specifications (Release 10 for carrier aggregation specifications). As to NFC, patent disclosures in claim and detail description for each NFC patent are compared to the NFC Forum standard specifications (Activity, Digital, Protocol, LLCP (Logical Link Control Protocol), NDEF (Data Exchange Format), RF/Analog, RTD (Record Type Definition), and Tag Operation). As to Zigbee, patent disclosures in claim and detail description for each Zigbee patent are compared to the IEEE 802.15.4-2006 standard specifications.

To find the innovation leadership for Smartphone wireless technologies, a competitive index (C.I.) is devised by considering the IPR leadership in each key technology and IPR share (C.I. of 100 means the top for all three Smartphone wireless technologies): As of 2Q 2012, Samsung is the leader followed by Philips(+NXP), LG & Qualcomm, Nokia, Motorola(+Freescale), InterDigital, Sony, ETRI, and ZTE.
