LTE Devices, Patent War, and Patent Pool

According to GSA (Global mobile Suppliers Association) there were 45 manufacturers for 161 LTE-enabled user devices as of July 2011:
LTE user devices are Modules, Tablets, Notebooks/netbooks, PC Cards, Smartphones, Routers, and USB dongles.

Among 45 manufacturers, only 9 manufacturers - Ericsson, Huawei, LG, Motorola, NEC, Qualcomm, RIM, Samsung, and ZTE - were LTE essential patents shareholders based on TechIPm's LTE patent analysis:

To find the key IPR holders for the LTE patents, a keyword search of the USPTO patent data base has been performed. For completeness, patent data in the lists of patents declared essential to 3GPP LTE appear at the ETSI IPR Online website is also included. More than 1,400 LTE related patents, issued and published applications in the US as of Aug. 31, 2011, are analyzed to find essential patent candidates for LTE RAN (Radio Access Network) standards. 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 184 patents 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, TI, and ZTE.

How about other 36 manufacturers? Are they free from patent lawsuit?

Recently, NGMN Board recommended that all stakeholders should participate in an effective LTE patent pool formation to avoid further delays in LTE licensing:;6/Regulation,_Standards,_Spectrum;31/NGMN_Board_Recommendation_on_LTE_Patent_Pool;2621?1&PHPSESSID=5fa3ddd96ac550ca5ac597f0a6b21909.

Who will be key players for the LTE patent pool?, Are there enough essential patents for the pool?
