Right-Pricing Cellular Patent Licensing in 4G and 5G Connected Vehicles

Great expectations for IoT hinge on cellular technology

There is strong consensus and enthusiasm in government, business and among commentators about the Internet of Things, with its multi-trillion dollar market potential. While financial and other benefits will be reaped by many vendors and users in various different industries, as well as by consumers, several generations of patented technologies developed largely by companies within the telecommunications industry over many years—up to and including newly introduced 5G—are enabling this major opportunity.

Despite cellular technologies being developed by and hitherto implemented largely among a relatively limited group of telecommunications industry OEMs producing cellular products—most significantly mobile phones as well as mobile network equipment—the variety and numbers of prospective technology implementers in IoT are far greater. While SEP licensing is well established for mobile phones and base stations—with thousands of agreements since the 1990s worth many billions of dollars every year—the industry is still in the throes of establishing the basis and pricing for use of these technologies in various different IoT applications including cars, domestic appliances, industrial robots and remote meters.

This article conservatively estimates total FRAND charges for licensing all cellular SEPs in vehicles, based on value derived therefrom and reflecting some recent court judgements on FRAND charges in other devices including smartphones. 

How to charge?

Since the early days of the 2G mobile phone industry, SEP owners most often licensed their cellular patents at royalty rates calculated as a percentage of phones’ average wholesale (i.e. unsubsidized) selling prices. One reason for this is that OEMs anticipated the subsequent downward trend in mobile phone prices, which fell dramatically following the introduction of digital cellular with 2G in the early 1990s. OEMs did not want to be locked into fixed dollar-per-unit (“DPU”) royalty charges that would increase in percentage terms as manufacturing costs were rapidly declining.

While royalties for 2G/3G/4G cellular connectivity in a mobile phone have usually continued to be charged as a percentage of the end-product selling price, the value established there—when stated as an equivalent DPU figure—is a key consideration. As average mobile phone prices increased with the widespread adoption of 3G smartphones from the late 2000s and 4G smartphones several years later, SEP licensors have, in many cases, at the behest of OEMs, “capped” percentage-based royalties to maximum DPU figures to ensure royalties paid do not exceed the value of additional features deemed less dependent on cellular connectivity. 

Similarly, DPU pricing is also applicable for other cellular-enabled “devices” including, for example, PCs and connected vehicles. There are also bountiful ways in which connectivity is exploited in these with various applications. However, a vehicle OEM, for example, would quite reasonably refuse to pay royalties for cellular SEPs that are calculated as a percentage of a vehicle’s cost or value in alloy wheels or leather seats. 

I have argued for many years against the proffered valuation methodology of basing royalties on a percentage of the sales price of a component or “smallest-saleable patent practicing unit (SSPPU)” and this approach has been soundly rejected by US and European courts.  The US Ninth Circuit Court of Appeals has ruled in Federal Trade Commission v. Qualcomm that “the district court’s analysis [relying on an SSPPU approach]is still fundamentally flawed. No court has held that the SSPPU concept is a per se rule for “reasonable royalty” calculations . . . .” Similarly, in Germany in Nokia v Daimler, the Mannheim court stated that the “royalty provided in [Daimler’s] counter-offer is not reasonable, as the reference value used in the top-down approach in the form of the average purchase price of [TCUs] is unsuitable. This reference value prevents [Nokia] from participating adequately . . . in use of the technology in the saleable end product.” (Unofficial translation.)

I am not commenting here on how aggregate royalties can or should be apportioned among SEP owners. Elsewhere, I have commented on the inaccuracies and other shortcoming in apportioning royalties based on the counts of declared-essential or judged-essential patents. 

Where to license?

While I and many others have also long argued it is also rather simpler and more efficient to license at the entire device level—as has always been the case in mobile phones—the Court of Appeals additionally ruled in the above that it is the patent licensor’s prerogative to license where it wishes. 

As discussed below, the value of cellular functionality to a connected vehicle is at least around $30 per unit, regardless of where licensing occurs in the production supply chain, and irrespective of the different formulae that could be used to calculate that figure with licensing at different stages in that supply chain. 

Valuation benchmarks

While there has never been consensus in the telecommunications industry that aggregate royalties for SEPs should be capped—with significant dissent by various licensors including Qualcomm—maximum aggregate figures proposed by some leading companies that declare many patents essential to cellular standards—when correctly interpreted and applied—provide at least some conservative valuation benchmarks. Court determinations of FRAND royalty rates for individual licensors—also as percentages of unsubsidized wholesale handset prices—in a few different cases have been based upon or cross-checked using such aggregate figures:

• 6% to 10% for LTE by Judge Selna in TCL v. Ericsson, which was subsequently overturned on appeal;
• 8.8% for LTE (i.e. 4G) by Justice Birss in Unwired Planet v. Huawei;
• 5% for 3G and 6% to 8% for 4G by the Shenzhen Intermediate Court in Huawei v. Samsung.

However, adjustments to the above are warranted because some source figures have been misinterpreted and incorrectly applied or alternative figures could have been reasonably selected as aggregate royalties in determining FRAND rates for the parties’ portfolios. 

Prior to Judge Selna’s judgement being entirely vacated on appeal, I showed he had muddled single-mode and multi-mode licensing rates in pages 5 to 7 of my critique of his “top-down” SEP royalty rate valuation analysis. As LTE was being first standardized in 2008, patent owner announcements from April that year proposed individual and aggregate single-mode LTE royalty rates. This was for like-for-like comparisons with claims of ”less onerous” licensing for rival 4G technology WiMAX at “much lower” rates and with patent pooling at a “predictable cost”. Only a couple of companies also mentioned their proposed multi-mode rates. It is only since then that Apple’s iPhones and Android-based smartphones have been multi-mode devices needing licensing of more than one generation of technology. The first of these smartphones, including even 3G, was not introduced until the second half of 2008. The aggregate rates Judge Selna used in deriving an aggregate FRAND rate of 6% to 8% (his judgement also cites a figure “not higher than 10%”), reflected only the value in LTE and not that in 2G and 3G. The correct figure for LTE handsets (i.e. multimode devices) with his methodology should, therefore, have been 11% to 15%, including an additional 5% for 3G, and conceivably more for the inclusion of 2G. 

Justice Birss also uses the “total royalty burden” in his FRAND rate determinations. He indicates, for a 4G multimode handset, “the aggregate implied by either party’s case (Huawei’s 13.3% and Unwired Planet’s 10.4%).” The average of these two figures is 11.9%. 

According to Strategy Analytics, the global wholesale average selling prices for LTE handsets (i.e. overwhelmingly multi-mode including 2G, 3G and 4G standards) were $270 in both 2018 and 2019. That equates to $29.70 to $40.50 per handset at multi-mode royalty rates of 11% and 15%, respectively.

While cellular SEP licensing revenues for Ericsson, InterDigital, Nokia and Qualcomm alone amount to many billions of dollars per year, that is overwhelmingly from mobile phone licensing with revenues understating value in cross licensing among these and other companies. For example, as Ericsson and Nokia used to have large handset device operations and still have major cellular network equipment businesses, licensing fees paid in cash among those and many other cellular industry companies significantly reflect netting off rather higher nominal charges. Major implementers—including Apple, Huawei, LG and Samsung with substantial market shares of device sales in recent years—tend to generate little or nothing in cash royalties for SEP licensing while they seek to minimize license fee outpayments through cross licensing. 

Licensing fees paid also understate value because many OEMs have remained unlicensed due to free-riding with patent “hold-out” and because some OEMs do not have licensing programs but own patents for defensive purposes. 

SEP value in vehicles versus smartphones

The value of SEP technology to vehicles is provided in various ways and applications to manufacturers, consumers and vehicle fleet operators. In some respects, this value exceeds the value that the same technology confers on a smartphones. As well as enabling in-vehicle information and entertainment systems, cellular technology:

• Connects all of a car’s occupants concurrently, while smartphones tend to be used by only one person;
• Enables remote vehicle diagnostics for maintenance, asset management tracking and route management in trucks; 
• Improves vehicle safety with C-V2X, for example, with collision avoidance alerts introduced in 4G: thus saving lives by reducing the numbers of millions dying and many more suffering from serious accidents on the roads worldwide each year; and
• Can continuously connect various third parties, including the vehicle OEM, insurance providers and fleet management service providers.

The value derived from the one-off licensing charges is also elevated in connected vehicles because these have longer working lives than smartphones.  Cars, for example, typically have 14-year lifespans before scrappage, versus seven years for mobile phones, while users in developed countries replace their phones about every 18 months.

In consideration of all the above and the “maximum aggregate rates” relied upon by the judges, as discussed above, an aggregate SEP value of $30 to $40 per smartphones is also reasonably applicable per connected vehicle for multimode 2G/3G/4G licensing. While DPU royalties are explicitly not derived as a percentage of a vehicle’s cost or price, it is notably that the above figures correspond to less than 0.1 % of average selling prices for cars—at $37,800 in the US and $27,400 globally— two orders of magnitude higher than for LTE smartphones at $270 over the last couple of years. 

The future in 5G

As indicated above, the connected car market is expected to quadruple in size over the next five years, with additional growth in adjacent markets that are also dependent on cellular connectivity. As well as buoying average prices and stimulating new vehicle sales volumes, connected vehicle capabilities in cars and trucks—with Markets and Markets’ market definition, or with my broader market definition—will inevitably provide among the best opportunities for vehicle OEMs to differentiate their products and bolster profit margins. For example, capabilities including C-V2X are being enhanced in 5G over what is possible in 4G, with improvements such as enhanced positioning to enable increasingly autonomous and even self-driving vehicles. While market definitions include the cost or price of tech hardware and software, utility and value to consumers will grow as autonomous capabilities—provided by C-V2X, sensors and AI—save lives while relieving occupants from driving and enabling them to work, relax or sleep. 

While cost and value to manufacturers and consumers in connected vehicles is almost entirely still in 2G, 3G and 4G today, this will increasingly be in 5G with it expecting to dominate the flow of gross additional cellular connections (a leading indicator) and account for 31 percent of all established connections worldwide by 2025. That justifies significant additional royalties for 5G in vehicles, as some cellular SEP owners are already obtaining through the licensing of 5G smartphones and other devices.

One-stop-shopping is best in IoT

While bilateral licensing is possible in IoT including connected vehicles—as it is in mobile phones—the reduced transaction costs and other benefits inherent in platform-based licensing or patent pooling is highly attractive to both licensors and licensees in IoT, as I wrote in my previous article here very recently. While all the major cellular SEP owners have preferred to license bilaterally to the relatively small number of handset OEMs, most prefer now to license these SEPs into the numerous different vertical sectors in IoT through a platform or pool. For example, while there are differences in analysis and opinion about exactly what proportion of cellular SEPs Avanci represents, there is broad agreement that it, with its 39 licensors, has most of them. Avanci licenses all its 3G and 4G SEPs for $15 per connected vehicle—the price of a car wash—regardless of how many TCUs, modules or modem chips the vehicle contains.
