InterDigital’s Smartphone LTE Patent Prosecution: Something Wrong or Strategy?

TechIPm’s research for patents that are directly related to LTE smartphone implementation in the current US market as of January 10, 2013 shows that 6 key market players - Apple, InterDigital, LG, Motorola, Nokia, Qualcomm, Samsung – dominate the IPR share (68 %) among the 24 IPR shareholders. The IPR share counts both issued patents and published applications in the USPTO.

In analyzing the patent prosecution status of the IPR shareholders, one interesting point is found: InterDigital’s rate of abandonment during the prosecution (abandoned due to failure to respond to an OA) is very high (34 %) compare to other dominant IPR shareholders (Apple 2 %, LG 1 %, Motorola 9 %, Nokia 3 %, Qualcomm 0 %, Samsung 5 %). Furthermore, InterDigital’s granting rate as issued patents is relatively low (31 %) compare to other dominant IPR shareholders (Apple 59 %, LG 84 %, Motorola 69 %, Nokia 70 %, Qualcomm 53 %, Samsung 65%).
