LTE Standard Essential Patents Nokia v InterDigital Analysis 4Q 2013
- 1. Comparative Analysis of LTE Standard Essential Patents : Nokia v. InterDigital 4Q 2013 ©2013 TechIPm, LLC All Rights Reserved www.techipm.com
- 2. I. Methodology ©2013 TechIPm, LLC All Rights Reserved www.techipm.com
- 3. 1. Methodology 1. Search for LTE related patents. Search the current USPTO database for published and issued patents as of 4Q 2013 Search the ETSI database for LTE standard specifications 3GPP Release 10 technical specifications (LTE-Advanced) for LTE RAN (Radio Access Network): PHY: TS 36.211, 212, 213, 305 (Positioning Technology) L2/L3 Protocols: TS 36.321, 322, 323, 331, 304, 300 *LTE RAN products: LTE UE (cellular phones, smart phones, PDAs, mobile PCs, etc.) and base station (eNB) baseband modem and radio SW products ©2013 TechIPm, LLC All Rights Reserved www.techipm.com 3
- 4. 1. Methodology -2 2. Review the searched patents Categorize the identified patents through the evaluation process by technology in the standard specifications Key technology components for an implementation of the LTE baseband modem: OFDM/OFDMA (Frame & Slot Structure, Modulation), SC-FDMA (PUSCH, PUCCH), Channel Estimation (UL RS, DL RS, CQI), Cell Search & Connection (PRACH, DL SS), MIMO (Transmit Diversity, Spatial Multiplexing), Resource Management (Resource Allocation, Scheduling), Coding (Convolution, Turbo), Power Control, HARQ, Carrier Aggregation, and Positioning Technology. Key technology components for an implementation of the LTE radio protocol: Random Access, HARQ, Channel Prioritization, Scheduling (Dynamic, SPS), Protocol Format (PDUs, SDUs), Radio Link Control (ARQ), PDCP Process (SRB, DRB, ROHC), Security (Ciphering, Integrity), System Information, Connection Control, Mobility (Handover, Inter-RAT, Measurements), VoIP, and Carrier Aggregation. ©2013 TechIPm, LLC All Rights Reserved www.techipm.com 4
- 5. 1. Methodology -3 3. Evaluate the level of essentiality Essentiality Index (EI): E1 : Patent disclosure is weakly related to LTE technical specifications E2 : Patent disclosure is partially related to LTE technical specifications E3 : Patent disclosure is related to LTE technical specifications overall E4 : Patent disclosure is strongly related to LTE technical specifications *To be a potential essential patent candidate, EI should be E3 or E4. *Standard Essential Patent (SEP): A patent has one or more claims that cover completely some part of the standard specification. ©2013 TechIPm, LLC All Rights Reserved www.techipm.com 5
