Samsung v. Apple Smartphone LTE Patent Comparative Analysis

  1. 1. Samsung v. Apple Smartphone LTE Patent Comparative AnalysisTechIPm’s research for comparative analysis of Samsung’s and Apple’s patens directly related toLTE smartphone implementation in the current US market as of 3Q 2012 shows that Apple holdsLTE patent portfolio comparable to Samsung’s in patent numbers and qualities (which can beused in counter attack defense).Samsung holds 84 patents (44 issued patents, 40 published applications). Among 84 patents, 65patents are identified as patents for LTE baseband modem and 19 patents are identified aspatents for LTE protocol SW.Apple holds 91 patents (48 issued patents, 43 published applications). Among 91 patents, 77patents are identified as patents for LTE baseband modem and 14 patents are identified aspatents for LTE protocol SW.Comparison of patent disclosures with key LTE technologies shows that Samsung’s and Apple’sis distributed among all the key technology components for an implementation of the LTEbaseband modem. Samsung’s patent portfolio shows a relative competitiveness in coding andSC-FDMA. Apple’s patent portfolio shows a relative competitiveness in channel estimation,coding, and MIMO (Ref. Figure 1).As to the key technology components for an implementation of the LTE radio protocol, Apple’spatent portfolio shows a relative competitiveness in mobility technology and Samsung’s patentportfolio shows a relative competitiveness in scheduling technology (Ref. Figure 2).For more information, please contact Alex Lee at alexglee@techipm.com©2012 TechIPm, LLC All Rights Reservedhttp://www.techipm.com/
