    LTE Essential Patents Landscape 2009 Q2 LTE Essential Patents Landscape 2009 Q2 Presentation Transcript

    • 3GPP LTE Essential Patents Landscape 2Q. 2009
    • 1. 3GPP LTE Essential Patent Candidates by Assignee This report analyzes the lists of patents declared essential to 3GPP LTE appear at the ETSI IPR Online website. The declared essential patents include patent applications in pending and published as well as issued patents in the United States (USPTO) before May 1, 2009. Total of 579 declared essential patents are included in the analysis. By the status of the applications, the patents are further classified into the total of 140 issued patents, the total of 244 published applications, and the total of 195 pending applications. Fig. 1 shows the distribution of the declared essential patents (in this report, we call these as the potential candidates for the essential patents) among assignees. Key interpretation: the active contenders for essential patents IPR competition are Qualcomm, Interdigital, Nokia, Nortel, Texas Instruments (TI), Samsung, LG, ETRI, Sony, and Icoding. As of April 30, 2009, the Qualcomm is the leader followed by Interdigital.

    • 2. 3GPP LTE Essential Patent Candidates by Specification Technical specifications for the 3GPP LTE are classified as TS 36 series. Fig. 2 shows the distribution of the potential candidates for the essential patents among specifications. Key interpretation: the top 3 most declared specifications as the 3GPP LTE potential candidates for the essential patents are TS36.211 (physical channels and modulation), TS36.213 (physical layer procedures), and TS36.300 (overall description; Stage 6).

    • 3. 3GPP LTE Essential Patent Candidates by Assignee and Specification Fig. 3.1, 3.2, and 3.3 show the GPP LTE Essential Patent Candidates by Assignee and Specification for Issued patents, published applications, and pended applications respectively. Key interpretation: as for the total of 140 issued patents, Qualcomm (total of 44) and Nokia (total of 42) are the leader followed by Nortel (total of 22) as for the specifications, TS36.211 (total of 42) is the top followed by TS36.213 (total of 22) as for the total of 244 published applications, Interdigital (total of 106) is the leader followed by Qualcomm (total of 59) as for the specifications, TS36.211 (total of 85) is the top followed by TS36.300 (total of 68)
    • 3. 3GPP LTE Essential Patent Candidates by Assignee and Specification -2 as for the total of 195 applications in pending , Qualcomm (total of 104) is the leader followed by LG (total of 31) and Interdigital (total of 30) as for the specifications, TS36.211 (total of 59) is the top followed by TS36.213 (total of 50)

    • Fig. 3-2 GPP LTE essential patent candidates by assignee and specification: issued patents
    • Fig. 3-3 GPP LTE essential patent candidates by assignee and specification: published applications
    • Fig. 3-4 GPP LTE essential patent candidates by assignee and specification: applications in pending
    • 4. 3GPP LTE OFDM/MIMO Essential Patent Candidates Specification TS 36.211 and TS 36.211 are related with the OFDM/MIMO which is the most important technology for the communications between the user mobile device and the base station. This technology filed is also the most competitive for getting the essential patents among contenders. Fig. 4 compares the number of essential patent candidates declared as 3GPP LTE OFDM/MIMO related technology. There are total of 280 patents for the specification TS 36.211 + TS 36.213. Key interpretation: Qualcomm (total of 125) is the leader followed by Nortel (total of 42)
