Didn't ZTE do an analysis of 4G LTE patents which put IDCC much higher than this?

From your link.

An essential patent is defined as patent that contain one or more claims that are infringed by the implementation of a specification for standardized technology. Thus, if a LTE product is implemented following the standard specifications, it should infringe some essential patents. To evaluate the essentiality of a LTE patent, patent disclosures in claim and detail description for each LTE patent are compared to the final versions of the 3GPP Release 8 technical specifications.

Total of 152 patents (15 issued patents and 137 published applications) are identified as the potential candidates for LTE RAN essential patent. The LTE IPR shareholders for essential patent candidates are Ericsson, ETRI, Freescale, Huawei, InterDigital, LG, Motorola, NEC, Nokia, Nortel, NSN, Qualcomm, RIM, Samsung, and TI. Among 15 LTE essential patent candidate shareholders, the top 5 IPR shareholders - InterDigital, LG, Nokia, Qualcomm, and Samsung - are appeared as the key member candidates for a successful LTE patent pool formation and operation.


Total of 84 patents are identified as the potential candidates for LTE baseband modem essential IPR and total of 68 patents are identified as the potential candidates for LTE protocol SW essential IPR. Leading in IPR share indicates governance in licensing and a high in profit expectation through licensing royalty. As to the essential IPR share in baseband modem products, Qualcomm is the leader followed by LG, Samsung, Nokia, and InterDigital as of December 31, 2010. As to the essential IPR share in protocol SW products, LG is the leader followed by Qualcomm, InterDigital, Nokia, and Samsung as of December 31, 2010.
