Apple's Smartphone LTE Patents Landscape

TechIPm’s research for the patent ownership change to Apple in USPTO shows that Apple holds 91 patents (48 issued patents, 43 published applications) directly related to LTE smartphone implementation in the current US market as of 3Q 2012. Among 91 patents, 77 patents are identified as patents for LTE baseband modem and 14 patents are identified as patents for LTE protocol SW.

Comparison of patent disclosures with 3GPP technical specifications shows that, among TS36 specifications, TS36.211 (physical channels and modulation) was the top followed by TS36.213 (physical layer procedures) and, among key technologies, Channel Estimation and MIMO were the top category that Apple’s LTE patents are distributed.
