Steve Jobs and Apple introduced the iPhone, the first smartphone, in January 2007, and a waiting world was introduced to incredible volume both in standards and in patents. Global data usage now exceeds one billion gigabytes a month and half of all mobile devices are smartphones. The growth in mobile standards from the first generation in the 1980s to the development of the fifth generation today has witnessed an amazing array of technology, one release will capture the public interest only to be replaced within a short span of time by a new technology, more useful, more ubiquitous than the last one. The key question for discussion in today's world of standards and patents is how to license the standards essential patents for the smartphone at a fair price.
Let's begin this discussion with standards. The first generation of standards included devices such as the pager, the cordless telephone and private mobile radio and systems such as the Advanced Mobile Phone System (AMPS) and the Total Access Communication System (TACS.)1 According to Tondare, Panchal and Kushnure "AMPS was introduced in 1982 providing bandwidth of 40MHz, offering 832 channels for subscribers with data rate of 10Kbps." This step forward required better batteries as did all the generations of mobile devices.
The second generation introduced new techniques, Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA) and roaming. The most widely used protocol was the Global System for Mobile Communication (GSM.) The United States used TDMA and CDMA while most of the world adopted GSM.
The third generation increased speed and capacity adding services such as streaming, mobile internet access, video calling and internet protocol television (IPTV.) The Third Generation Partnership Project (3GPP), a standards group with representation from standards organizations in the United States, Europe, China, Japan and Korea developed the International Mobile Telecommunications-2000 (IMT-2000) with data rates of 200 kbps. CDMA developed an overlay that allowed data rates over 300 kbps.
The fourth generation introduced the convergence of wired and wireless. "4G is an all IP-based integrated system will be capable to provide 100 Mbps for high mobility and one Gbps for low mobility, with end-to-end QoS (quality of service) and high security. The user services include IP telephony, ultra-broadband Internet access, gaming services and High Definition Television (HDTV) streamed multimedia."2
Work on 2G standards involved more than 886,000 person hours from 200 companies from 13 countries over 15 years. Work on 4G standards "…is ongoing and has already taken more than nine years, and more than a million person hours from participants from more than 320 companies."3
Work on patents kept pace. Baron and Pohlmann found 180,215 declarations of standards essential patents (SEPs) essential to ETSI mobile standards in September 2015. Table 1 shows the number of patent declarations as it grew year by year.4
The number of standards subject to declared SEPS is 2,134. The number subject to more than 10 declared SEPs is 1,007. The number subject to more than 100 SEPs is 308. The number subject to more than 1,000 declared SEPs is 44 and of these 43 are from ETSI. Long Term Evolution (LTE) has the largest number of declarations with 61,831 followed by Universal Mobile Telecommunication Service (UMTS) with 43,658 and Universal Terrestrial Radio Access Network UTRAN with 18,757.5
In 2014, TechIPm found that very few of the patents claimed as essential to LTE were essential to the Radio Access Network (RAN) sections of LTE. There are over 490 sections in the LTE standard. A patent essential to the LTE standard may or may not be essential to every device that implements the standard. The RAN sections of the LTE standard that are included in every mobile device are less than 70 sections. TechIPm found only 447 essential RAN patents compared to the 50,000+ claimed patents essential to the LTE standard. Assuming this proportion holds there were roughly 550 patents essential to the RAN sections of the LTE standard by September 2015.
A patent is a negative right to exclude others from making, using or selling one's invention and it includes the right to license others to make, use or sell it. A patent is a grant of some privilege, property or authority, made by the government or sovereign of a country to one or more individuals.6 In their book, Cases and Materials on Patent Law, Martin Adelman and his fellow authors quote White, Patent Litigation: Procedure and Tactics and U.S. statutes.
To obtain as damages the profits on sales he would have made absent the infringement, i.e., the sales made by the infringer, a patent owner must prove: (1) demand for the patented product, (2) absence of acceptable non-infringing substitutes, (3) his manufacturing and marketing capability to exploit the demand, and (4) the amount of profit he would have made.
When actual damages, e.g., lost profits, cannot be proved, the patent owner is entitled to a reasonable royalty. 35 U.S.C. § 284. A reasonable royalty is an amount "which a person, desiring to manufacture and sell a patented article, as a business proposition, would be willing to pay as a royalty and yet be able to make and sell the patented article, in the market, at a reasonable profit." Goodyear Tire and Rubber Co. v. Overman Cushion Tire Co., 95 F.2d 978 at 984…7
Given the volume of smartphone sales, a patent owner of a smartphone SEP would certainly find it easy to prove (1) demand for the patented product; because it is covered by standards; (2) absence of acceptable non-infringing substitutes; (3) his manufacturing and marketing capability to exploit the demand; (4) the amount of profit he would have made. Since sales of smartphones have been brisk and Apple and Samsung are the only profitable manufacturers, perhaps unless the complaint was made by Apple or Samsung, this may be difficult to prove (4). It would be less difficult to prove (4) for a chip maker.
Many cases make use of the fifteen Georgia-Pacific Factors to determine reasonable damages.i Fong, Lai and Liu found, "Using LexisNexus [LexisNexis], we have identified cases where judges have referenced the Georgia-Pacific case since 1995. There are 96 cases cited this case (Appendix 1). After some manual sorting, we have identified those cases where these factors have been discussed (35 cases out of 96, i.e. 36 percent) and included them in our study. This set of cases was used to determine the inter-relationship between the various factors and categorise them to have a structured approach to use the Georgia-Pacific 15 factors."8
Fong et al cite a Durie and Lemley 2010 study that "…have suggested a structured approach to calculate reasonable royalties based on the 15 factors cited in Georgia-Pacific case. They suggested that most of the 15 factors essentially answered three questions:
Fong et al note in their conclusion, "…it has also been demonstrated the Georgia-Pacific factors can be quantified using the Nash bargaining solution. This can serve as a guideline for expert witnesses to base their reasonable royalty calculations on. In addition, the solution can also be used in practical licensing negotiations to guide practitioners."
onsidering item number two of the Georgia-Pacific factors: "The rates paid by the licensee for the use of other patents comparable to the patent-in-suit", the "rates paid" not only vary widely, but use a different base on which to compare the patents-in-suit. The question of royalty based on the price of the device in which a standard is practiced or royalty based on the components that practice the standard is still subject to cases in court and license practice in the market.
Armstrong, Mueller and Syrett argued that:
The data show that royalty stacking is not merely a theoretical concern. Indeed, setting aside off-sets such as "payments" made in the form of cross-licenses and patent exhaustion arising from licensed sales by component suppliers, we estimate potential patent royalties in excess of $120 on a hypothetical $400 smartphone—which is almost equal to the cost of device's components.9
Just using publicly announced royalty rates, Armstrong, Mueller and Syrett found:
In the table shown above, Armstrong, Mueller and Syrett identified the companies that have publicly disclosed royalty rates for their LTE portfolios. For each company, they then calculated the royalty that would be applicable to a $400 device based on the announced rate.10
Nortel filed for bankruptcy and sold their patents to the Rockstar Consortium including Apple, Microsoft, Ericsson, Sony, and BlackBerry in July 2011. Google bought Motorola in May 2012. ZTE joined the Via Licensing patent pool in October 2012. Rockstar sold the Nortel patents to RPX in December 2014. Google joined the Via Licensing patent pool in April 2015. Nokia bought Alcatel-Lucent in April 2015.
Note that there are two patent pools listed. Usually there is only one patent pool per technology so that licensees may gain the benefit of a license from many companies without stacking the royalty rates—that is without adding the rates. In the case of LTE, the patent pools add to the royalty stack. In 2007, the major LTE patent holders said they would publish their rates and that the combined rate would be a high single digit number, that is less than 10 percent. The first seven on this list are at 14 percent royalty, so the publication of rates approach never quite lived up to its billing.
Motorola offered to license its SEPs at what it considered the RAND rate of 2.25 percent.
The U.S. District Court used six factors in its analysis (1.) The court introduced the parties and their relationship to one another, (2.) The court provided background on standards, Standards Setting Organizations (SSOs) and the RAND commitment, (3.) The court developed a framework for assessing RAND terms, specifically a modified version of the Georgia-Pacific factors:
The US District Court decided that the royalty rate and range as follows:
Key factors cited include:
Section 540: To this end, in the course of a hypothetical negotiation with a SEP owner, the implementer must ask herself as a rational business person, "What is the most I can pay for a license to this particular SEP or portfolio of SEPs—knowing that I might have to license all SEPs in the entire standard—while still maintaining a viable business?"
The court looked at the Via Licensing 802.11 Licensing Pool and the MPEG LA H.264 Licensing Pool as examples to use in setting a royalty rate and avoiding royalty stacking.
Section 578: Microsoft uses as an additional comparable … the royalty rate that a third- party company, Marvel Semiconductor … pays for the intellectual property in its WiFi chips. The court agrees that the Marvell rate provides an indicator for 802.11 RAND under Factor 12 of a hypothetical negotiation because the experiences of Marvell, a third party, tend to establish what is customary in the business of semiconductor licensing.
Section 580: …the Marvell WiFi chip…enables the device to use the 802.11 Standard to transmit and receive information on radio frequency carriers. Otherwise stated, the WiFi chip uses the 802.11 Standard to communicate wirelessly.
Section 581: In the past Marvell has charged $3.00 to $4.00 per chip for WiFi chips of the kind its sells to Microsoft. 6. Section 582: Marvell pays a royalty and licensing fees to ARM Holdings … ARM provides Marvell with patent licenses and "design and know-how" Marvell needs to make its 802.11 compliant chips … Marvell pays ARM one percent of the purchase price of the chip (3-4 cents per chip.)
Section 585:Â Marvell considers the ARM rate an appropriate benchmark because the rate is based on the selling price of the chip, not the sale price of the end-user product into which the chip is embedded. Example testimony: A one percent royalty on a chip placed in an $80,000 Audi A8 would be $800, or about 267 times the retail price of the chip.
Another case citing the smallest saleable unit is Cornell University v. Hewlett-Packard Co., 609 F. Supp. 2d 279, 283 (2009.)vi
II. The Way Forward
No one denies that a patent owner should be able to charge whatever royalty they negotiate for a patent unrelated to a standard. The key question is whether a patent owner of a standards essential patent should be able to charge a premium when much of the value of the patent is derived from the international standards organization adopting the patented technology.
In the absence of industry coming together in a patent pool with the major players assembled to avoid royalty stacking and seek a reasonable royalty based on the component practicing the standard, the courts have done the heavy lifting. The results are not all that patent owners may desire, but the results do provide patent owners with reasonable royalty based on patent law. This royalty may not pay for all research and development, but it does provide, considering the volume of smartphones in the market and yet to enter the market, a considerable sum for those patent owners willing to do the serious work of proving their patent claims.
It is time for industry to reclaim the lead from the courts. Industry, not the courts should determine reasonable royalty for cellular standards essential patents by coming together in a single patent pool and developing a royalty that will stand the test of a court challenge.
