Using the Innography, which is a business intelligent solution for IP management (http://www.innography.com/), the patent portfolios for NFC 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. 20 2009, the key IPR holders and their IPR shares for NFC are as follows:
Sony (229), Nokia (130), MS (76), Philips (67), Broadcom (65), Samsung (58), Motorola (57), NXP (43), First Data Co (22), Qualcomm (22), IBM (19), Vodafon (18), and Inside Contactless (17).
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 NFC, Sony, Nokia, and IBM form a leader group in portfolio management capability.
