To find the key IPR holders for the LTE patents, a keyword search of the USPTO patent data base has been performed. For completeness, patent data in the lists of patents declared essential to 3GPP LTE appear at the ETSI IPR Online website is also included. More than 1,400 LTE related patents, issued and published applications in the US as of Aug. 15, 2011, are analyzed to find essential patent candidates for LTE RAN (Radio Access Network) standards. To evaluate the essentiality of a LTE patent, patent disclosures in claim and detail description for each LTE patent are compared to the final versions of the 3GPP Release 8 technical specifications.
Total of 184 patents are identified as the potential candidates for LTE RAN essential patent. The LTE IPR shareholders for essential patent candidates are Ericsson, ETRI, Freescale, Huawei, InterDigital, LG, Motorola, NEC, Nokia, Nortel, NSN, Qualcomm, RIM, Samsung, TI, and ZTE.
Among the 184 essential patent candidates 53 patent candidates are issued (including in allowance status) as of Aug. 15, 2011: LG (25), Nokia (7), Nortel (6), Motorola (5), Samsung (3), InterDigital (2), TI (2), Ericsson (2), Qualcomm (1).
For details, please refer LTE Essential Patent Candidates Data:
LTE Essential Patent Candidates Data is the TechIPm's product based on LTE patents research for US market leader among LTE UE (cellular phones, smart phones, PDAs, mobile PCs, etc.) and base station (eNB) product manufactures. LTE Essential Patent Candidates Data provides assignee, patent number, related 3GPP TS36 specifications, and the key technology components for an implementation of the products.

LTE Patent Portfolio Evaluation Service
TechIPm, LLC (www.techipm.com) provides patent portfolio evaluation service for LTE commercial products.
Methodology
1. Search for LTE related patents.
l Search the current USPTO database for published and issued patents
l Search the ETSI database for LTE standard specifications
l 3GPP Release 8 technical specifications for the LTE RAN (Radio Access Network):
l PHY: TS 36.211, 212, 213
l L2/L3 Protocols: TS 36.321, 322, 323, 331, 304
l * LTE RAN products: LTE UE (cellular phones, smart phones, PDAs, mobile PCs, etc.) and base station (eNB) baseband modem and radio SW products
2. Review the searched patents for essential patent candidates.
l Review the patents in portfolio
l 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, and HARQ.
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, and Mobility (Handover, Inter-RAT, Measurements).
l 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.
3. Patent analysis.
l Comparative analysis among the patent portfolios (e.g. Nortel v. Motorola) by technology
l Interpretation for competitive intelligence
Deliverables
MS excel file for the patent essential patent candidates (patent number, standard specification section number, technology category, and essentiality level).
MS power point file for patent analysis.
