3 1 Executive Summary Emerging technologies such as 4G-LTE attract the lion s share of industry and media attention. However, 2G and 3G wireless networks remain highly relevant, currently supporting over 80% of all mobile phone activity. Trends suggest the use of 2G and 3G technologies will expand dramatically during the next three to five years as the world s two largest markets, India and China, open their doors wide to mobile phone usage. Ericsson, Nokia, Qualcomm and Alcatel-Lucent are among those who developed the building blocks of today s wireless world. They collectively control the majority of all patents in this space. Nokia, LG Electronics and Qualcomm alone own more than 43 percent of all seminal patents (i.e., determined to be strong based on a set of parameters). The playing field has evolved dramatically in recent years, causing these brands to slowly fade from the minds of consumers. However, they will continue to exert an influence on current market leaders such as Apple, Google and Samsung, who control today s mobile device ecosystem. 2G and 3G technology patents have been at the center of ongoing patent wars and they can be expected to fuel a significant escalation in activity during the next five years as top patent holders seek to monetize their portfolios. Leading patent holders have already launched initiatives against major competitors, with some having sold patent rights to various companies. It is highly likely, given the increasing pressure on these companies to generate revenue, that many will become more aggressive by entering into new agreements with patent privateers to monetize their assets. The result will likely be an increase in litigation and licensing. So, who stands to benefit in this evolving marketplace? Which companies control the largest number of patents and the largest number of seminal patents in the world of 2G and 3G technologies? Which companies are best positioned to leverage monetization efforts? These are some of the questions addressed in this report. We explore key 2G and 3G patent holders, providing details on the number and category of overall, standard-essential and seminal patents. The report delves into companies that control a large percentage of seminal and standard-essential patents. Nearly nine percent of seminal 2G and 3G patents are currently held by certain companies, and approximately five percent of all standard-essential patents are held by two companies - Innovative Sonic Ltd. and Vringo Infrastructure Inc. This report also reveals that these companies that hold key 2G and 3G patents have remarkably high patent monetization potential. irunway 2013 Confidential Page 3 of 26

4 2 Introduction 2.1 Overview of 2G & 3G Technology 2G was commercially launched in It introduced digital signaling via packet data in telecommunications, and provided reduced power consumption and noise levels. It also proposed better security methods with digital encryption techniques coupled with lower power usage. SMS, MMS and were a few packet-based services introduced by 2G. Although highly advanced markets have reached a stage where 2G networks are now being switched off, 2G technologies still account for over 80 percent of connections in China and 90 percent in India - the two largest mobile markets in the world. With successive technologies such as 2.5G, 2.75G and 3G, the era of ever-increasing data rate demands skyrocketed across the globe. While packet data was introduced in 2G, higher data rates and better data services were brought by 3G. Attractive services such as Mobile TV, Video on Demand, Video Conferencing, Location-Based Services and Global Positioning System (GPS) gradually grew into a necessity for a majority of mobile users. Statistics 1 suggest that, as of 2012, more than 500 operators across 185 countries have deployed 3G networks, pointing to the fact that mobile users in more than three-quarters of the world s markets have access to 3G services. 2.2 Technical Highlights of 2G & 3G The 2G Advantage Lower power consumption, better security and better bandwidth usage are the key advantages of 2G over its precedent technologies. 2G introduced digital encoding in telecommunications, resulting in better compression and multiplexing of voice data than its preceding analog encoding. The advantage: 2G supported a larger number of calls in the same radio bandwidth and ensured lower power consumption that improved battery life in mobile phones. Digital encryption methods introduced in 2G provided better security and privacy to mobile users. Short Message Service (SMS) and Multimedia Message Service (MMS) became the first form of packet-based services introduced in 2G, marking the beginning of data services on mobile phones /359/ irunway 2013 Confidential Page 4 of 26

5 The 3G Advantage 3G entered the market with the advantage of increased data rates available to mobile users for services such as Mobile TV, Location-Based Services, video calls and internet browsing on the move. It also provides variable data transfer speeds ranging from 128 kbps to 3 mbps depending on the speed with which the mobile device is moving within the network. Beyond mobile telephony, the higher speeds allowed 3G connections in PCs, gaming consoles, tablets and any other portable device that could benefit from a faster and higherquality internet connection. 3G also provides users with better security through user authentication capabilities when communicating with other wireless devices. 3G boasts of better power control methods for both uplink and downlink, with the network using a target Signal-to-Interference Ratio (SIR) to adjust its output power. It also improves spectrum utilization through shared channels in the radio interface, thus making it more effective than 2G networks. 2.3 Comparative Study of 2G, 3G & 4G-LTE 2G 3G 4G-LTE Services Introduced Data services such as text messaging (SMS), multimedia messaging (MMS), internet access & SIM cards.

Figure 2: Technology Evolution Tree of 2G & 3G U.S. Patent Filings (Source: irunway analysis based on patent data from USPTO) 3.3 Analysis of Seminal Patents The entire 2G and 3G portfolio was analyzed and ranked using irunway s portfolio analysis solution COMPASS SM. A list of seminal 2G and 3G patents was generated based on a combination of manual research and a proprietary algorithm for strength calculation. The seminal patent set constituted the top 5% of ranked patents. The strength of the patents was determined based on multiple parameters such as infringement detection, number of independent and dependent claims, technology activity rate, backward and forward references, age of the patent, etc. Table 3 illustrates the patent distribution for top seminal patent holders, their share of seminal patents and their share of all 2G and 3G patents: irunway 2013 Confidential Page 9 of 26

While the top six companies listed in the table above collectively hold 60% of all seminal patents, these three companies alone own a combined share of 43%. In order to better understand the strength and quality of the portfolios that companies hold, irunway analyzed the ratio of the number of seminal patents to their respective portfolio sizes. Figure 3 shows this metric for the top seminal patent holders: irunway 2013 Confidential Page 10 of 26

Beyond the top patent holders (by portfolio size), certain smaller companies hold key patents in the 2G and 3G domain. In fact, companies having a smaller portfolio but with a higher percentage of seminal patents could be viewed as having higher patent monetization potential. Also: LG holds a significantly stronger portfolio compared to other large players in the industry. With a relatively high number of seminal patents, companies such as Vringo and General Dynamics could be viewed as having a small, yet strong, patent portfolio.

15 4 Key Players in the 2G & 3G Patent Landscape 4.1 Ericsson Ericsson focused its 2G and 3G patent investments in the domain of Security, Power Management and Data Transfer Rate, and has over 1,500 U.S. patents. It has a strong presence in the Communication Quality and Services domains. Ericsson started its research and IP investments on 2G and 3G ahead of all other companies and owns the largest portfolio in this field. The company also has a good number of seminal and standard-essential patents. Ericsson and Samsung entered into a license agreement on mobile technology in 2002, wherein Ericsson granted Samsung a non-exclusive worldwide license to its patent portfolio for GSM, TDMA, GPRS, EDGE and WCDMA mobile standards 2. Figure 7: Technology Evolution Tree of Ericsson s 2G & 3G U.S. Patent Filings (Source: irunway analysis based on patent data from USPTO) 2 irunway 2013 Confidential Page 15 of 26

16 4.2 Nokia Nokia holds the most number of seminal patents (roughly 17%) and owns patents in all key technologies related to 2G and 3G, especially in Communication Quality, Data Transfer and Security. It also owns the most number of standard-essential patents (227), and has strength in the Data Transfer Rate and Security domains. The company has been actively involved in monetization through patent sales.. Recently, Nokia sold around 500 of its global patents to Vringo, which includes 109 U.S. patents covering 2G, 3G and 4G technology 3. In September, 2011, MOSAID Technologies Inc. acquired Core Wireless Licensing, which had a portfolio of roughly 2,000 global wireless patents and applications, including 2G and 3G patents originally filed by Nokia 4. Nokia and Qualcomm, market leaders in this domain, entered into a 15-year patent licensing agreement in 2008, which gave Nokia access to all of Qualcomm s patents 5. Figure 8: Technology Evolution Tree of Nokia s 2G & 3G U.S. Patent Filings (Source: irunway analysis based on patent data from USPTO) irunway 2013 Confidential Page 16 of 26

17 4.3 Qualcomm Qualcomm has a significant number of patents and patent applications worldwide in CDMA, OFDMA and other technologies. It also owns a nearly 13% share of all seminal patents in the 2G and 3G space, standing third to Nokia and LG. Qualcomm has the second highest number of standard-essential patents (146). It is the leading patent holder of core patents in advanced 3G mobile technologies, as well as in CDMA and WCDMA standards 6. CDMA2000 1X EV-DO and later revisions use Qualcomm s High Data Rate (HDR) system to support packet data rates of up to 2.4 Mbps. Rapid expansion and adoption of CDMA and OFDMA worldwide has ensured uniform growth of license and royalty revenues for the company since the mid-1990s 7.

20 5 Monetization of 2G & 3G Patents The last decade has witnessed an increase in patent infringement lawsuits in the telecommunications industry. Often referred to as Patent Wars, these legal battles are predicted to continue at a more active pace in the near future. It all started in the mid-2000s when the 2G market was growing at a steady pace and all companies holding significant IP in this field started looking at monetization options. The major market players sued each other over various technologies, often with the aim to remove a competitor s product from the market. These cases, interestingly, worked both ways, and a majority of them resulted in cross-licensing deals between the litigants. Companies also entered the market through acquisition of strong patents, attracting attention from several industry players who were prepared to shell out millions to own such IP. Here are some examples: One important case involving multinational companies was the lawsuit between Ericsson and Samsung. In early , Samsung answered Ericsson s claims of patent infringement by countersuing the Swedish multinational, alleging infringement of 20 of Samsung s patents, including those related to 2G and 3G wireless standards and device functions. In the same year, Ericsson entered into a licensing deal relating to 2G, 3G and LTE technologies with Unwired Planet. In 2007, Qualcomm filed patent infringement lawsuits against Nokia in GSM technology. Following this, Nokia paid licensing fees to access all of Qualcomm s patents 10. Brandywine Labs has sued over 39 service providers to date, including AT&T, Verizon and Century Link, over DSL patents 11. In 2012, a group of eight telecom service providers, including Alcatel-Lucent and EarthLink, entered into separate patent agreements with visual voic provider Klausner Technologies for its consumer and enterprise visual voic technologies 12. Fractus, a company that designs and manufactures antennas for mobile handsets and wireless devices, filed lawsuits in 2009 against ten mobile phone companies, claiming irunway 2013 Confidential Page 20 of 26

21 infringement of its patents covering internal multiband antennas common to all cell phones, tablets, laptops, navigation devices and other wireless portable devices 13. In 2013, InterDigital filed lawsuits against Samsung, Nokia, Huawei and ZTE claiming infringement of patents applicable to wireless devices with 3G and 4G capabilities 14. In 2013, Ericsson has sued Micromax, an Indian tablet and Smartphone maker, alleging infringement of patents that cover wireless technologies Potential Licensing & Litigation of 2G & 3G Patents It is interesting to note that almost 9% of seminal 2G and 3G patents are held by few companies. About 5% of all standard-essential patents are owned by Innovative Sonic Ltd. and Vringo Infrastructure Inc. Table 6 shows the total count of issued U.S. patents of some of the active companies in this sector, including their ownership of seminal and standardessential patents, and the percentage of seminal and standard-essential patents in their respective portfolios: Company Total Count Count of Seminal Patents % of Seminal Patents in Portfolio Count of Standard Essential Patents % of Standard Essential Patents in Portfolio Vringo Infrastructure Inc % % Core Wireless Licensing % 1 8.3% Pendrell Corporation % 0 0% Gemalto % 0 0% Intellectual Ventures % 0 0% Table 6: U.S. Patent distribution of Few Companies (Source: irunway analysis based on patent data from ETSI & USPTO) Vringo Infrastructure Inc. Vringo works on development and monetization of mobile technologies and intellectual property. The company s portfolio includes a combination of patents for technology developed internally and the 500 global patents and applications that it acquired from b2afea490fa5/idcc_news_2013_1_2_general_releases.pdf 15 irunway 2013 Confidential Page 21 of 26

22 Nokia 16 in The company has also filed some recent patent infringement lawsuits against ZTE Corp in the U.K., France, Australia and Germany of Vringo s U.S. patents are relevant to 2G and 3G technology. These patents are spread across all the Level 1 categories, with the most number of patents belonging to Communications Quality (28) and Services (17). 19 of these 74 patents are standard-essential. 10 of its patents are featured in the top seminal patents ranking. Core Wireless Licensing S.A.R.L. Core Wireless Licensing is a wholly-owned subsidiary of MOSAID, a leading IP management company. The company deals with development and monetization of intellectual property in the telecommunications space. Core Wireless Licensing, like Vringo, has also acquired patents that were initially filed by Nokia. 12 of Core Wireless patents are relevant to 2G and 3G, with a majority of its patents belonging to the Positioning and Power Management categories. 6 of the 12 patents have been ranked as seminal. Core Wireless has filed a lawsuit against Apple over one of its patents related to 3GPP standard-essential technology, which it had earlier acquired from Nokia 18. Pendrell Corporation Pendrell is an intellectual property investment, advisory services and asset management firm that is in the business of acquiring, commercializing, managing and licensing IP in the fields of tablets, Smartphone and other consumer electronics. Pendrell acquired approximately 125 patents and patent applications worldwide from Nokia through its wholly-owned subsidiary, Helsinki Memory Technologies (HMT) 19. The current patent portfolio that Pendrell holds includes inventions conceived by their employees or by global leaders such as IBM, Xerox and Phillips of Pendrell s patents are relevant to 2G and 3G technology, with five of these ranked as being seminal Agreement#.VHMorfmUer irunway 2013 Confidential Page 22 of 26

23 All of those 39 patents belong to the Level 1 category relevant to Security. Gemalto Formed in 2006 with the merger of Gemplus International and Axalto, Gemalto has been one of the leaders in the digital security domain 21. It provides software applications for personal security and is a major manufacturer of smart cards. 15 of Gemalto s patents are relevant to 2G and 3G technology and belong to the Security and Communication Quality categories. Four of these 15 are ranked seminal. In its 2011 annual report, the company announced temporary postponement of the signing of new licenses. 22 However, considering the strength of its portfolio and strong litigations it had filed in the past, the company could resume its monetization efforts. Intellectual Ventures Management LLC Intellectual Ventures Management LLC s portfolio, which is known as the IV portfolio, has over 70,000 acquired patents and patent applications and 3,000 patent applications for inhouse inventions 23. The company often acquires patents from smaller firms or individual inventors and aggregates them into a large portfolio, which now comprises patents relating to almost all technical domains. Recently, the company joined hands with NVIDIA to acquire the patent portfolio of IPWireless, a leader in wireless technologies 24. Its patents in the 2G and 3G domains primarily belong to Communication Quality, Data Transfer Rate and Security categories. The company earlier involved itself in lawsuits with corporations such as AT&T and Motorola over some of its telecommunications patents 25. The above companies have successful patent monetization programs in place and the industry may see more efforts from these patent holders to monetize their patents through effective licensing and litigation campaigns against key players in the market results#.vhmqppmuer Wireless-Patent-Assets-7dc.aspx irunway 2013 Confidential Page 23 of 26
