  4. 4. Executive Summary<br />LTE patent portfolios are researched for US market leader among LTE UE <br />(cellular phones, smart phones, PDAs, mobile PCs, etc.) and base station <br />(eNB) product manufactures. <br />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. <br />Total of 1327 LTE patents, issued and published applications in the US as of Dec. 31 2010, are analyzed to find essential patent candidates for LTE RAN (Radio Access Network) standards. <br />To evaluate the essentiality of a LTE patent, patent disclosures in claim and <br />detail description for each LTE patent are compared to the final versions of the 3GPP Release 8 technical specifications.<br />

  12. 12. 2.1 Essentiality Analysis <br />An essential patent is defined as patent that contain one or more claims that <br />are infringed by the implementation of a specification for standardized technology. Thus, if a LTE product is implemented following the standard specifications, it should infringe some essential patents. To evaluate the essentiality of a LTE patent, patent disclosures in claim and <br />detail description for each LTE patent are compared to the final versions of the 3GPP Release 8 technical specifications for the LTE RAN (Radio Access Network): <br />PHY: TS 36.211, 212, 213<br />L2/L3 Protocols: TS 36.321, 322, 323, 331<br />Total of 152 patents are identified as the potential candidates for LTE essential patents for the LTE RAN.<br />

  53. 53. A2. Patent Portfolio Development Method<br />A typical way to develop the essential patent is to participate in the <br />standardization process and try to get IPRs for the standards in parallel <br />(strategic alignment between standardization and IPR). <br /> <br />Without the strategic alignment between standardization and IPR process, <br />however, there is an alternative way to develop the essential patent portfolio <br />through patent engineering process. The LTE patent engineering process <br />utilizes the existing patent portfolio. <br /> <br />The patent engineering process for LTE essential patent development is as <br />follows.<br /> <br />
