To eval　uate the quality of Samsung's LTE IPR for OFDM/MIMO standards, patent disclosures for each essential patent candidate are compared to the technical specifications for LTE OFDM/MIMO standards (TS36.211 V8.70). Total of 21 patent applications published in the United States before Aug. 1 2009 in the lists of patents declared essential to LTE appear at the ETSI IPR Onl　ine are used in the analysis.

As for the most described field of technical specification, Physical Uplink Control Channel (PUCCH; Section 5.4) was the top in Samsung's OFDM/MIMO essential patent candidates.

As a measure for the essentiality of the candidates, Essentiality Index (EI) is eval　uated:

EI : Criteria
E0 : Patent disclosure is nothing to do with LTE technical specifications
E1 : Patent disclosure is weakly related to LTE technical specifications
E2 : Patent disclosure is partially related to LTE technical specifications, but required further analysis
E3 : Patent disclosure is partially related to LTE technical specifications
E4 : Patent disclosure is related to LTE technical specifications overall
E5 : Patent disclosure is strongly related to LTE technical specifications

Only 23 % of the Samsung's OFDM/MIMO essential patent candidates are classified as E2 and E1.

77 % (ten E3, two E4, and two E5) of the Samsung's OFDM/MIMO essential patent candidates are classified as high value of EI for the essentiality.

To eval　uate the quality of Nokia's LTE IPR for OFDM/MIMO standards, patent disclosures for each essential patent candidate are compared to the technical specifications for LTE OFDM/MIMO standards (TS36.211 V8.70). Total of 29 patents issued and published in the United States before Aug. 1 2009 in the lists of patents declared essential to LTE appear at the ETSI IPR Onl　ine are used in the analysis.

As for the most described field of technical specification, Down Link OFDM/MIMO (Section 6.3) was the top in Nokia's OFDM/MIMO essential patent candidates.

As a measure for the essentiality of the candidates, Essentiality Index (EI) is eval　uated:

EI : Criteria
E0 : Patent disclosure is nothing to do with LTE technical specifications
E1 : Patent disclosure is weakly related to LTE technical specifications
E2 : Patent disclosure is partially related to LTE technical specifications, but required further analysis
E3 : Patent disclosure is partially related to LTE technical specifications
E4 : Patent disclosure is related to LTE technical specifications overall
E5 : Patent disclosure is strongly related to LTE technical specifications

41 % of the Nokia's OFDM/MIMO essential patent candidates are classified as E2 and E1.

59 % (fifteen E3 and two E4) of the Nokia's OFDM/MIMO essential patent candidates are classified as high value of EI for the essentiality.

In recent press interview for “LG's Successful LTE-CDMA Handover"‎, Dr. Scott Ahn, President & CEO of LG Mobile Communications, expressed that LG will lead the 4G innovations based on about 300 LTE-related patents and experiences in leading the LTE standardization.

LTE IPR analysis by TechIPm showed that LG's LTE patent portfolio is in high quality compare to other LTE IPR holders: Nearly 90 % of the LG's OFDM/MIMO essential patent candidates are classified as high value for the essentiality.
