To evaluate the quality of Motorola'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 10 patent applications published in the United States before Aug. 1 2009, out of 103 essential patent candidates indentified by a keyword search, 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 Motorola's OFDM/MIMO essential patent candidates.
As a measure for the essentiality of the candidates, Essentiality Index (EI) is evaluated:
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
70 % (four E3 and three E4) of the Motorola's OFDM/MIMO essential patent candidates are classified as high value of EI for the essentiality.
