LTE Devices, Patent War, and Patent Pool

According to GSA (Global mobile Suppliers Association) there were 45 manufacturers for 161 LTE-enabled user devices as of July 2011: http://www.gsacom.com/news/gsa_336.php4.
LTE user devices are Modules, Tablets, Notebooks/netbooks, PC Cards, Smartphones, Routers, and USB dongles.

Among 45 manufacturers, only 9 manufacturers - Ericsson, Huawei, LG, Motorola, NEC, Qualcomm, RIM, Samsung, and ZTE - were LTE essential patents shareholders based on TechIPm's LTE patent analysis:

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. More than 1,400 LTE related patents, issued and published applications in the US as of Aug. 31, 2011, 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. Total of 184 patents are identified as the potential candidates for LTE RAN essential patent. The LTE IPR shareholders for essential patent candidates are Ericsson, ETRI, Freescale, Huawei, InterDigital, LG, Motorola, NEC, Nokia, Nortel, NSN, Qualcomm, RIM, Samsung, TI, and ZTE.

How about other 36 manufacturers? Are they free from patent lawsuit?

Recently, NGMN Board recommended that all stakeholders should participate in an effective LTE patent pool formation to avoid further delays in LTE licensing: http://www.lteportal.com/MediaChannel/Articles/LTE__LTE-Advanced;6/Regulation,_Standards,_Spectrum;31/NGMN_Board_Recommendation_on_LTE_Patent_Pool;2621?1&PHPSESSID=5fa3ddd96ac550ca5ac597f0a6b21909.

Who will be key players for the LTE patent pool?, Are there enough essential patents for the pool?

Samsung's Mistake for InterDigital's Patents Acquisition

According to a S. Korea's news media, Seoul Economic Daily, Samsung finally decided that it will not participate in auction for InterDigital's patents: http://economy.hankooki.com/lpage/industry/201108/e20110819164352120250.htm.

After Apple's acquisition of Nortel's patents, Samsung had expressed that it is interested in bidding for InterDigital's patents:http://www.slashgear.com/samsung-may-bid-on-interdigital-patent-portfolio-according-to-source-03169241/.

Samsung told to the media that there will be more lost then benefit for buying the patents because of price bubble in InterDigital's patents. It may be true if Samsung do not consider its strong competitor- Apple.

According to TechIPm's analysis for LTE patents, some part of InterDigita's LTE patent portfolio have a relative competitiveness over Samsung's, and it may be a good tool to Apple to attack Samsung, if it acquires InterDigital's patents.

InterDigital Patent Acquisition Strategic Options

Following the recent big deal regarding Nortel's patents and Motorola's patents, InterDigital's patents are scheduled to be the next big acquisition deal.

As to the seller, it is a good opportunity considering the uncertainty of future money making power in emerging LTE licensing market: InterDigital's licensing power in LTE is expected to be weaker compare to the situations in 2G and 3G based on TechIPm's LTE essential patent analysis over the past 3 years.

As to the buyers, it is also a good opportunity not only to make up their current LTE patent portfolio but also to get additional cash flow source through the existing InterDigital's licensing agreement.

Qualcomm's LTE Patent Governance

Qualcomm have enjoyed the governance in patents on the Code Division Multiple Access (CDMA) technology it pioneered. As every 3G network uses CDMA technology, Qualcomm was able to license its patents in exchange for a royalty payment that's 4-5% of selling prices on 3G enabled phones.


Recently TechIPm LLC researched LTE patent portfolios for US market leader among LTE UE (cellular phones, smart phones, PDAs, mobile PCs, etc.) and base station (eNB) product manufactures. Total of 1250 LTE patents, issued and published applications in the US as of May 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.


Total of 72 patents are identified as the potential candidates for LTE baseband modem essential IPR and total of 62 patents are identified as the potential candidates for LTE protocol SW essential IPR. As for the essential IPR share in baseband modem products, Qualcomm (27 %) is the leader followed by Samsung (18%), LG (18%), InterDigital (7%), Nokia (7%), Motorola (6%), and TI (6%) and as for the essential IPR share in protocol SW products, LG (43 %) is the leader followed by InterDigital (19%), Qualcomm (18%), and Nokia (16%) as of May 31 2010.

The top 5 IPR shareholders - InterDigital, LG, Nokia, Qualcomm, and Samsung (total IPR share of 87%) - are appeared as the key member candidates for a successful LTE patent pool formation and operation.


Top 5 LTE essential IP shareholders’ patent portfolios, classified by the key technology components for an implementation of the LTE baseband modem, are compared to excess the innovation competitiveness. Qualcomm’s patent portfolio was distributed among all the key technology components for an implementation of the LTE baseband modem.


Among the total of 134 identified patents as the potential candidates for LTE RAN essential IP only 7 candidates are the issued patents. As the prosecution for the published applications is an ongoing process, it is necessary to watch for a possible IP landscape change. A complete LTE RAN essential IP landscape is expected in two to three years as the current prosecution process for the published and unpublished pending patent applications are finished for a complete set of issued patent data pool.
