LTE patent pool accounts for around 10% of LTE standard essential patents IPR share in the US

Google announced addition of its LTE patents acquired from Motorola Mobility to Via Licensing's LTE Patent Pool (Ref. http://www.usatoday.com/story/tech/2015/04/09/google-joins-wireless-patent-group/25478395/). Via Licensing's LTE Patent Pool Licensors are AT&T, China Mobile, Clear Wireless, Deutsche Telekom, DTVG Licensing, Google, Hewlett-Packard, KDDI, NTT DOCOMO, SK Telecom, Telecom Italia, Telefonica, ZTE. Before the joining of Google, ZTE was only the LTE smartphone manufacture among LTE Patent Pool Licensors.

In recent TechIPm, LLC’s 4G LTE standard essential patents research for the US market leader among 4G LTE UE (cellular phones, smart phones, PDAs, mobile PCs, etc.) and base station (eNB) product manufactures and innovators  (Ref. http://techipm-innovationfrontline.blogspot.com/2015/01/4g-lte-patents-for-standard_8.html), Google ranked 6th in IPR share for 4G LTE standard essential patent candidates as of 1Q 2014. By the addition of Google as its licensors, Via Licensing's LTE patent pool now accounts for around 10% of LTE standard essential patents IPR share in the US.

Essential Patent Information Portal: S.Korea's National Strategy for IT Leadership

The Korean Intellectual Property Office (KIPO) opened the essential patent information portal (http://www.epcenter.or.kr/) in order to support IPR (Intellectual Property Right) in standardization activity. Operation of the portal site is a part of S. Korea's national strategies to keep global leadership in information technology by implementing the strategic alliances in "R&D - Standardization - IPR".

The portal provides the essential patent DB in the global standardization organizations such as ISO, ITU, IEEE, ETSI, and 3GPP as well as the patent pools such as MPEG, IEEE 1394, ATSC, AVC/H.264, and VC-1.

The portal also provides mentoring services in essential patent development for S. Korean industries through the operation of essential patent expert pool.

LTE Patent Pool Shareholder Candidates

Total of 1238 LTE patents, issued and published applications in the US as of May 1 2010, are analyzed to find essential patent candidates for LTE RAN (PHY & Radio Protocols) standards. LTE PHY (physical layer) standards are described in 3GPP specifications TS36.211, TS36.212, and TS36.213. LTE radio protocols standards are described in 3GPP specifications TS36.321, TS36.322, TS36.323, and TS36.331.

LTE RAN (Radio Access Network) standards are essential for an implementation of mobile user equipments (cellular phones, smart phones, PDAs, PCs, etc.) and base station (eNB) products. 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. Total of 134 patents are identified as the potential candidates for LTE RAN essential patent.

The LTE IPR shareholders for essential patent are Ericsson, ETRI, Freescale, Huawei, InterDigital, LG, Motorola, NEC, Nokia, Nortel, Qualcomm, RIM, Samsung, and TI. Among 14 LTE essential patent candidates shareholders, LG is the leader (30%). 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.
