  • 4. Executive Summary
    LTE patent portfolios are researched for US market leader among LTE UE
    (cellular phones, smart phones, PDAs, mobile PCs, etc.) and base station
    (eNB) product manufactures.
    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.
    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.
    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.

  • 10. 1.2 LTE Patent Search Details
    • Search parameters for the ETSI IPR Online data base:
    • 11. Search keywords for the DELPHION’s USPTO patent data base
  • II. Patent Evaluation
  • 12. 2.1 Essentiality Analysis
    An essential patent is defined as patent that contain one or more claims that
    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
    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):
    PHY: TS 36.211, 212, 213
    L2/L3 Protocols: TS 36.321, 322, 323, 331
    Total of 152 patents are identified as the potential candidates for LTE essential patents for the LTE RAN.

  • 47. A1. Essential Patent Claim Drafting Strategy
    Analysis of claims for the essential candidates suggests several strategy factors in drafting essential patent applications:
     
    Strategy 1. Write the claim using several statutory claim types.
     
    <Case study>  
  • 48. A1. Essential Patent Claim Drafting Strategy -2
  • 49. A1. Essential Patent Claim Drafting Strategy -3
  • 50. A1. Essential Patent Claim Drafting Strategy -4
  • 51. A1. Essential Patent Claim Drafting Strategy -5
  • 52. Fig. A1 US20060285484
  • 53. A2. Patent Portfolio Development Method
    A typical way to develop the essential patent is to participate in the
    standardization process and try to get IPRs for the standards in parallel
    (strategic alignment between standardization and IPR).
     
    Without the strategic alignment between standardization and IPR process,
    however, there is an alternative way to develop the essential patent portfolio
    through patent engineering process. The LTE patent engineering process
    utilizes the existing patent portfolio.
     
    The patent engineering process for LTE essential patent development is as
    follows.
