TechIPm researched over 1700 patents related to the LTE standard issued by the USPTO as of June 2015. By comparing patent disclosures to 3GPP technical specifications, they identified 495 patents as potential LTE standard essential patents. LG Electronics accounted for 16% of these patents, followed by Samsung Electronics, Qualcomm, and others. The research also found that active patent monetization entities, including patent trolls, accounted for 28% of LTE standard essential patents, indicating increasing potential litigation risks.

LTE Standard Essential Patents 2Q 2015: LTE-Advanced Enhancements
TechIPm researched patents for the LTE standard regarding UE (cellular phones, smart phones, PDAs, mobile PCs,
etc.) and base station (eNBs, Femtocells, Relays) products, issued in the USPTO as of June 30, 2015. TechIPm’s
research identified more than 1700 patents that are related to the LTE standard.
To evaluate the essentiality of a patent for the LTE-Advanced standard and the key features of the LTE-Advanced
Enhancements standard, patent disclosures in claims and detail description for each identified LTE related patent
are compared to the final versions of the 3GPP Release 10 technical specifications for the LTE RAN (Radio
Access Network), Release 11 technical specifications for CoMP, Release 12 technical specifications for EPDCCH
and D2D (Device to Device) Communications. Total of 495 patents are selected as the potential candidates of the
LTE standard essential patents (SEPs) (its patent disclosure is related to LTE technical specifications overall).
Among 39 IPR holders, LG Electronics accounts for 16% of the IPR share followed by Samsung Electronics,
Qualcomm, Optis Cellular Technology, InterDigital, Ericsson, Google and Nokia.
TechIPm’s research also uncovered increasing IPR share of the LTE SEPs by the active monetization entities
(entities exploit LTE SEPs for monetization purpose actively) including the patent trolls. IPR share of the LTE
SEPs by the active monetization entities accounts for 28%, which implies the increasing potential litigation risks.
TechIPm’s research identified many LTE SEPs owned by the active monetization entities that are used for several
