Using the Innography, which is a business intelligent solution for IP management (, the patent portfolios for 4G (LTE and Mobile WiMAX) mobile technologies are analyzed. To find the key IPR (issued patents and published applications) holders and their patent portfolios, semantic method is used for the keyword searching of the global patent data bases (USPTO, EPO, JIPO, KIPO, CIPO, WPO etc.)

As of Oct. 15 2009, the key IPR holders and their IPR shares for LTE are as follows:

Qualcomm (561), Nokia (327), InterDigital (315), Samsung (240), Ericsson (231), LG (194), Motorola (130), Alcatel-Lucent (117), RIM (93), and Nortel (88).

Using the identified key IPR holders' patents, patent portfolios are compared with respect to portfolio quality measures (citations, number of patents, and technology coverage) and portfolio utilization measures (revenue, global families, and litigation information).

As for the LTE, Qualcomm, Ericsson, Nokia, Samsung, InterDigital, and Nortel form a leader group in portfolio management capability.
