TechIPm researched patent portfolios of smartphone LTE IPR holders that do not manufacture LTE Smartphones (potential NPEs) in the current US market. The research reveals that InterDigital, Ericsson, Texas Instruments, and ETRI hold the most threatening smartphone LTE patent portfolios to smartphone manufactures.
InterDigital is the most notorious NPE in mobile handset industry. InterDigital holds more than 20 issued patents including seven LTE standard-essential patent candidates as of January 15, 2013. InterDigital’s LTE patents are developed well strategically to cover key technologies that are essential for LTE smartphone implementation.
As can be seen in recent patent lawsuit against Samsung and more than 2000 patents acquisition by Unwired Planet, Ericsson can be a potent NPE for LTE smartphone manufactures in the US. Ericsson holds more than 30 issued patents including three LTE standard-essential patent candidates as of January 15, 2013. Most of Ericsson’s LTE patents are characterized by high forward citations. Ericsson actually used two LTE standard essential patents in recent ITC litigation against Samsung.
Even if Texas Instruments manufactures some chipsets related to LTE smartphones, Texas Instruments can be a potential NPE for LTE smartphone manufactures considering its aggressive patent exploiting strategy. Texas Instruments holds nearly 20 issued patents including four LTE standard-essential patent candidates as of January 15, 2013.
ETRI is a well-known non-profit research institute in S. Korea. In year 2010, ETRI sued 22 mobile phone manufactures over 3G mobile patents. ETRI holds nearly 20 issued patents including three LTE standard-essential patent candidates as of January 15, 2013.
