Abstract
The IT sector is characterized by two market failures, the “tragedy of the commons” and the “tragedy of the anti-commons”, both of which must be resolved if IT innovation is to flourish and lock-in avoided. This involves a careful balancing of IPR protection and standard-setting, while avoiding hold-up and preserving opportunities for the significant innovation provided by the open source movement. The Author examines the shortcomings of the present system from a European Law perspective and expresses a plea for Open Standards in the interest of innovation and technological progress. As IT progresses, more and more products are compound items, incorporating technology co-owned by many different patent holders, co-manufactured by different producers, and interoperating with other complex products. A hold-up by a non-practicing entity or a rival using a single patent on a single component can kill an entire product. This article explores the criteria for “open standards”, and explains why royalty-free licensing of interoperability standards is appropriate in the software area (since RF standards can be implemented in both open source and proprietary software, thus allowing both models to compete on quality and functionality), while FRAND licensing is necessary for telecommunications. The notion of FRAND terms is further explored from a legal and economic perspective, explaining ways to determine fair pricing, and the need to ensure non-discriminatory terms in order to preserve competition in products implementing the standard. The article concludes with some comments on an interesting report by RAND Europe on “Trends in Connectivity Technologies and their Socio-Economic Impacts – Policy Options for the Ubiquitous Internet Society”.

Introduction By Carlo Piana
The article provides a very good explanation of why the interconnection between standardization and patents need a serious overhaul in order to address the concerns of competition failure in both the software and the general IT market, in the direction of what we call “Open Standards.”
The Author also analyzes remarkably well how – too frequently – RAND terms imply an actual discrimination against Free and Open Source Software implementations. Again, this is consistent with my experience, especially as a lawyer assisting clients in technology transfer agreements, mainly in the multimedia field.
Maurits adopts a position that clearly favors Open Standard without any ideological bias. He has a background that is very different from mine and those who are most likely to write on this Review. He finds for the case of Open Standards on a purely legal and technical point of view, out of a long and intensive experience on what RAND means in practical terms. Not ideology, indeed, but only simple and pertinent motives drive those who favor competition and technological advancement over hyper-exploitation of proprietary rights and an idolization of “Intellectual Property.”

A Tale of Two Tragedies – A plea for open standards, and some comments on the RAND report
At the root of the problem is a conflict between measures to resolve two different market failures: the “tragedy of the commons” and the “tragedy of the anti-commons”.
d. Open (published, objective, relevant, qualitative, and verifiable) criteria for technology selection. Standard agreements should be based on the relative merits and price of the technologies involved, to the extent possible. Of course, the advantages, performance and costs of technologies cannot always be known before adoption as a standard. But openness will aid a well-informed debate and choice, and minimizes the risk that standard setting is used as a cloak for an inefficient cartel or a tool to distort inter-technology competition
e. No overstandardization. A standard should be no more restrictive than necessary to meet the objective, and should allow maximum consumer choice without lock-in to a single vendor’s product. Where possible, design specifications should be avoided to ensure maximum competition within the standard on quality and product differentiation.
f. Open access to the standard. A standard is “open” only if it is well-documented and published, and available for implementation for all interesting parties, members of the standards body and outsiders alike. This has several key components, relevant for IPR Policies of standards bodies:
Unfortunately, a contract of mutual restraint can exist only if and so long as everyone plays by the rules. If one patentee breaks ranks and charges the highest royalty it can get away with, would the others grin and bear it, and lower their fees to absorb the price increase? It has been suggested that this would in fact happen, even that it would be “fair and reasonable” and consistent with competition law and FRAND promises for a non-vertically-integrated licensor to extract an amount close to full monopoly rent for a patent, leaving the crumbs for the other licensors and licensees. Consumers will not suffer, the argument goes, since a rational analysis of an “ultimatum game” indicates that (a) licensors of complementary essential patents will restrain themselves and seek only the difference between the royalty charged by the first licensor and the monopoly rent, so as to avoid a “Cournot complements” problem, and (b) licensed manufacturers will maintain the price for the end product and lower downstream profits (reducing their reward for innovation and risk downstream).
First, in the EU (and unlike Section 2 of the Sherman Act in the US), Article 102(a) and (c) TFUE prohibit unfair pricing or unjustified discrimination even in the rare case where no ex ante competition existed, so long as consumer harm ensues from excessive or discriminatory pricing. A “first mover takes all” approach could cause consumer harm by discouraging cooperation by other patentees and reducing investments by licensees in setting and implementing the standard, while the prospect that this is allowed in standard setting generally would dampen the incentives for dynamic competition by developing new technologies that could be used for future standard generations. Article 102 TFEU is appropriately applied where excessive or discriminatory pricing discourages standard implementation, investment in R&D for future standards, or future standard setting, or where it results in a “Cournot problem” or a “game of chicken” (see below). In the US, this may be caught by Section 5 of the US FTC Act.
i. A comparison with royalties and terms that other owners of essential patents reading on the same standard charge for their complementary patents (“proportionality analysis”);
ii. A comparison with royalties and terms that the patent owner itself charges for other, comparable, technologies (“proxy analysis”);
– The Scattered World scenario (the Internet in 2020 as collection of competing networks based on closed technology) reflects a “future of cutthroat monopolistic competition, unrestrained by active and effective antitrust and other regulation […]. The fragmentation of competition and low levels of vertical and horizontal integration have as a counterpart low levels of inclusion and worrying levels of inequality.”
– The Connected World scenario (the Internet in 2020 as a network based on open technology, driven by public investments and collaboration between firms) paints a “future where companies collaborate […] [and] governments […] take a cooperative lead in setting rules to optimise global public value creation […]. [F]irms have to compete (and make their money) on the merits of what they provide rather than the ability to exclude rivals. […] [I]nteroperability is a powerful public good, and governments are particularly vigilant against the risk of foreclosure by «bottleneck» firms or proprietary standards, using antitrust regulation, support for open standards and targeted public procurement to ensure a sustainably level playing field with high quality of service and reasonable prices. A potential limiting factor is that the speed of innovation […] is slowed by the natural pace of government initiatives […]. This world is very inclusive, including excellent technologies to assist those that need assistance to participate.”
For each scenario, RAND analyzes the expected status of innovation, consumer choice, privacy, social cohesion and equality, and identifies a number of critical problems, positive developments, and uncertainties. Experts were then asked to look back from the future and identify the key policy choices that will create desirable outcomes and those that create problems. The report discusses IPRs, privacy, data protection, infrastructure investment, e-commerce and other policy issues. Interesting conclusions are also drawn with respect to open standards and interoperability and net neutrality. RAND mentions, for instance that “The interconnectedness of the [Internet] challenges competition as the sustainable engine of continual improvement. Network externalities favour 'tipping' into monopoly and competition weakens” and the report worries that this may give rise to “a desire to limit interoperability [more] than a desire to innovate and offer effective choice.”
RAND concludes (p. 132) that Europe and most other major jurisdictions have not tried to regulate the Internet, but “as its spread and importance increase, this may no longer be possible, especially as other regulated activities ‘escape’ on-line and new policy concerns emerge.” The report warns that alternatives to regulation should be considered early in the policy process. For instance (p. xxvi), “the EC can encourage efficient competition among technologies and discourage inefficiently-high incompatibility, through creation or coordination of multi-stakeholder platforms and networks, and by applying multi-stakeholder governance principle. These would be enabling the adoption of common standards and market wide approaches to public policy concerns.” Open standards as defined above would appear to present a perfect mix of flexible multi-stakeholder arrangements, ensuring an adequate balance between the need to foster private sector innovation and the need to avoid technological lock-in or gridlock. Indeed, the RAND Report (p. 145) identifies a dozen or so of key goals for DG Information Society to pursue, which include:
– “Guarding openness and open networks”;
– “Champion common standards and pre-competitive collaboration”;
– “Champion interoperability in all its forms”
Drawing attention to economic analysis and using existing literature, the RAND report identifies various tools and associated challenges to achieve these goals (p. 141 ff), which it is worthwhile to mention:
– RAND proposes to use a range of ex ante and ex post regulation such as spectrum allocation, competition regulation, telecommunications pricing, interconnection, content regulation, fair competition and merger regulation, consumer protection, privacy, etc. At the same time, it identifies as a key challenge “to balance lightness of touch with credible effectiveness, […] and to prevent capture and/or foreclosure that distort markets and the development of the Internet.” Following the principles of open standards set out above should go a long way to meet this challenge, by maintaining adequate involvement of the private sector, while preventing capture and foreclosure.
– RAND approves of EC involvement in IPR regulation, to provide fair returns on risky inventive activity and as a market-based tool to signal where ideas are best applied. Interestingly, the report warns about the “the one-size-fits-all nature of the most common forms of IPR protection”. The open standards approach described above is useful to avoid the problems of this “one-size-fits-all” IPR protection, for instance, by allowing for a royalty-free standards approach for software interoperability and royalty-bearing standards in telecommunications and hardware. Other key challenges RAND mentions are “the potential for failure in the market for IPR, the possibility that market power in the market for innovation will spill over into markets for goods and services or vice versa and the possibility that predatory use of IPR […] and strategic incompatibility may undercut the hoped-for benefits.” Again, the open standards framework described above would address these concerns, by encouraging standard setting to address incompatibility failures, and ensuring that the necessary patents are available on FRAND terms.
– RAND encourages standard-setting and support for standard-compliant products, including by thoughtful procurement policies in favour of open standards. RAND adds: “Key challenges here are to maintain openness of standards (to avoid lending public support to proprietary standards), to balance the interoperability advantages of standardisation against the potential loss of diversity and inhibition of innovation and to ensure that standardisation enhances the innovativeness and competitiveness of the European economy.” While the RAND Report does not further define what “openness of standards” means, and does not propose ways to balance the need for interoperability against the need to maintain product diversity and innovation, it is submitted that the open standards principles mentioned above provide the solution that fits perfectly.
In one respect, however, there is a curious point in RAND’s analysis, concerning the role of competition law to guarantee a system of open standards that maintains innovation while preventing IPR gridlock. The RAND Report (p. 131-132) worries about “the tendency of Internet markets to tip into monopoly” but then warns:
“Anticompetitive behaviour can’t always be detected or prohibited ex ante, but ex post remedies (after lockin has occurred) may be too late, and there may be no counterfactual evidence to demonstrate that alternatives are viable if lock-in is widespread. Moreover, many of the specific activities that firms might use for predatory purposes (e.g. proprietary standards, low “penetration” pricing, etc.) are also essential in order to attract complementary content and services to Internet platforms capable of providing effective competition. Therefore, conventional antitrust policy may be less effective than consumer protection policy or supporting activities that enable users to coordinate moves to superior entrants, and participatory self-regulation may be more effective than IPR policy in deterring or overturning “stealth patents” in public standards.”
It is certainly legitimate to ask whether sector specific regulation should trump general antitrust regulation. With all due respect for the RAND Report, however, the conclusion in this paragraph and some of the thinking in it are at first sight hard to grasp.
Third, it should be recalled that the conception and growth of the Internet was government-funded and took place in a public sector and university environment. As the private sector takes over, and the risk of lock and hold-up emerges, it becomes more, not less, important to apply the principles of competition law.
More important, the public policy concerns under US law that advocate against use of antitrust law (the heavy burden of treble damages, the extraordinary high cost of defense as a result of extensive discovery, the risk of spurious litigation driven by contingency fee arrangements and class actions tried before juries, the need to prove intent) are absent or much less of a concern in the EU. Moreover, contrary to Section 2 of the US Sherman Act, Articles 102(a) and (c) TFEU prohibits excessive pricing and unjustified discrimination restricting downstream competition, and neither the courts nor the Commission are at liberty to ignore the legislator’s intent in that respect – a fortiori in the context of a FRAND promise.
A final comment concerns the statement that “many of the specific activities that firms might use for predatory purposes (e.g. proprietary standards, low “penetration” pricing, etc.) are also essential in order to attract complementary content and services to Internet platforms capable of providing effective competition.” Of course, low pricing or even giving away products or services may be legitimate in order to foster a network effect or attract business in a two-sided market. Similarly, building products based on proprietary technology like Apple’s iPod and iTunes is a legitimate business model. But using closed standards is not “essential” to attract complementary content or services – they are at best neutral in attracting complementary products, and tend to limit competition from substitutes.
To conclude: The RAND Report should be commended for recognizing the importance of open standards, and the criteria suggested above (including the conclusion that software-to-software interoperability standards should be patent or royalty-free where alternative revenue models exist) fit well within this framework. The paragraph on p. 132 should not be relied upon to throw out competition policy as a tool to maintain an open Internet. The comment that “conventional” antitrust policy is less effective, is better understood as a call for application of more innovative competition policy to strengthen open standards and foster consumer welfare and consumer choice, which are the objectives of competition policy. This is also consistent with comments elsewhere in the RAND Report (p. 100, emphasis in original):
“One key element is the importance of market competition in motivating and funding the development of innovations and in determining their availability, affordability and the resulting impacts on societal objectives. As a result, …effective competition policy remains essential. This raises new challenges for existing (technical and economic) regulators in relation to IPR, bundling and the treatment of joint ventures. More profoundly, it can change the synergistic relation that has traditionally existed between competition and consumer protection policies. To avoid capture, unjustified market distortion or an inappropriate balance of efficiency and innovation, it is necessary to ensure that competition policy promotes the efficiency benefits anticipated from competition rather than competition for its own sake.”
The EU may consider legislation that lays out a common set of rules for “fair play” in standards negotiation. But while regulation and IPR laws are blunt instruments, competition law properly and energetically applied allows intervention with surgical precision, permits remedies appropriate to address the precise problem and strike the right balance in the specific circumstances of the case, and creates flexible precedent that can be adjusted to new fact patterns. The Commission showed this when it negotiated a browser choice screen for Windows: Competition in browsers creates opportunities for alternative browsers that comply with open standards such as HTLM5, and if enough users exercise that choice, developers will have incentives to use those open standards as well, keeping the Internet open. This remedy, therefore, allows the market to speak. Let’s hope that the proposed revision of the Guidelines on Horizontal Agreements will reflect this open standards approach, that Commissioner Almunia will apply it, and that Commissioner Kroes will integrate competition policy when setting the Digital Agenda in her new position.

Interoperability is defined in the CFI Judgment in Microsoft (see below), para. 225 and following: “interoperability between two software products means the capacity for them to exchange information and to use that information mutually in order to allow each of those software products to function in all the ways envisaged.” This case concerned client-to-server and server-to-server communication, i.e., communication between two separate computer systems from different vendors in a network. See also para. 237: “the attainment of that objective assumes that non-Microsoft work group server operating systems are capable of receiving a specific message from a Windows client PC or work group server operating system and giving the required response to that message on the same conditions as a Windows work group server operating system and also of enabling Windows client PC or work group server operating systems to react to that response just as though it came from a Windows work group server operating system.” “Interoperability” between two computer systems should be distinguished from “compatibility” (whether a software or hardware component of a computer system can be substituted by another component without modification) and “portability” (whether a software or hardware component of a computer system or piece of software can be modified or adjusted to become part of another computer system). The Microsoft judgment did not cover those notions.

16 This, too, is not a new concept. In economics, this is called a problem of “Cournot complements”, named after the 19th century French economist who discovered that monopolist producers of complementary products may both block each other to extract monopoly rents, thus reducing output below the level that a single monopolist would have produced.

18 Broadcom Corp. v. Qualcomm Inc., 501 F.3d 297, 310 (3d Cir. 2007), III.A.2.b.: “Although a patent confers a lawful monopoly over the claimed invention […] its value is limited when alternative technologies exist […] That value becomes significantly enhanced, however, after the patent is incorporated in a standard […] Firms may become locked in to a standard requiring the use of a competitor’s patented technology. The patent holder’s IPRs, if unconstrained, may permit it to demand supracompetitive royalties.” See also C Madero Villarejo and N Banasevic, “Standards and Market Power”, Global Competition Policy, May 2008, 3.
19 Examples include the open Innovation Network (OIN, http://www.openinventionnetwork.com/), the Allied Security Trust (http://www.alliedsecuritytrust.com/http://www.alliedsecuritytrust.com/ ), Intellectual Ventures (http://www.intellectualventures.comhttp://www.intellectualventures.com ) and RPX Corporation ((http://www.rpxcorp.comhttp://www.rpxcorp.com ). While many of these may be beneficial, the model is not without risk to industry and consumers, since some of the profit-oriented entities might eventually be tempted to evolve into a Ponzi scheme, start holding up industry members that have not joined them, or resell the patents to third parties that do so.
20 Trolls are sometimes called “non-practicing entities”. New technology business models such as patent trading and “patent mining” are not necessarily bad. The existence of a market for patents may foster innovation, and allow firms or groups like the Open Innovation network to acquire patents for defensive purposes. At the same time, patent traps and royalty traps (“hold-up”) may discourage investment, where remuneration is taken away from the person who incurred R&D costs and bore the risk of product development – in a situation where bringing products to market may well be more costly, more risky and more beneficial to consumers. The key is to intervene to prevent inefficient hold-ups, including “opportunistic behavior on the part of patent owners that threatens to impose (1) static deadweight losses that are not justified by likely increases in dynamic efficiency, or (2) dynamic efficiency losses due to reduction in the incentive to participate in standard setting organizations or to engage in follow-up innovation.” See T. Cotter, “Patent Holdup, Patent Remedies, and Antitrust Responses”, Journal of Corporations Law, July 1, 2009, available at http://www.allbusiness.com/legal/civil-procedure-injunctions/12938773-1.htmlhttp://www.allbusiness.com/legal/civil-procedure-injunctions/12938773-1.html .

22 A well-known example is Microsoft’s financing of SCO to assert copyrights against Linux. See discussion at Groklaw, http://www.groklaw.net/staticpages/index.php?page=20061212211835541http://www.groklaw.net/staticpages/index.php?page=20061212211835541 .
23 An interesting example is Microsoft’s attempt to quietly auction off 22 Linux-focused patents to non-vertically integrated patent companies, explaining how these could be used to against Linux, which was unexpectedly thwarted by Allied Security Trust buying them and reselling them the Open Innovation Network.

The “license of right” is voluntary, and to have practical impact, additional incentives are probably required to encourage patent holders to agree with the license of right regime, for instance by facilitating the challenge of injunction patents, and by allowing “license of right” patents a greater presumption of validity. Moreover, defensive suspension of the “license of right patent” should be introduced, so as to allow defensive use.

26 “Open source software is software that is distributed under an open source license. The open source license gives anyone who is interested the right to access the program's source code and to copy, modify, and redistribute the program on a royalty free basis. There are many different open source licenses, but these characteristics are common amongst all of them. The most popular open source software programs also use an open source development methodology. An open source methodology provides any interested programmer with access into the program development process, and a democratic, open means for development and enhancement of the program. Software can be open source even if the developers do not adopt an open source development methodology. Open source software is complementary to, and is often included in, commercial software. […] Open source software can be an important source of innovation because it brings together people from different backgrounds and perspectives to work on and solve common business and IT problems. It is also an excellent approach for driving emerging standards and, in many cases; an open source software project can become the common implementation of a standard that is used by a large number of IT vendors and customers.” See IBM paper “Open Standards, Open Source, Interoperability and Government Policy”, May 11, 2009, http://www.marketwire.com/press-release/Ibm-NYSE-IBM-902622.htmlhttp://www.marketwire.com/press-release/Ibm-NYSE-IBM-902622.html .

30 This is not to suggest that closed standards are prohibited. Joint R&D not intended to create an industry standard may meet the conditions of the Joint R&D Block Exemption Regulation No. 2659/2000, OJ L 304/7 (2000) or the Guidelines for Horizontal Agreements, above. Similarly, proprietary standards fairly achieved may be beneficial in fostering radical “break-out” innovation like Sun’s Java and the very notion of cloud computing to “escape” the local desktop or local network. Thus, open standards should not be mandatory, so long as the owner of the proprietary standard – if and when it prevails and develops network effects – is curbed from using its dominance to stifle “break-out” innovation.. Also, closed standards should not be given any preference in procurement, and may not obtain all the benefits of European standards.

Access to the decision-making process can slow or distort progress, but skewed access can lead to distortions and inefficiencies in upstream technology competition and downstream implementation competition. Having objective, relevant and proportional rules for access appears to be the best way to strike the balance.

35 Cf. Article 101(3) TFEU. Interoperability refers to the ability of information and communication technology systems and the business process they support to exchange data with fidelity and to enable sharing and utilization of information and knowledge. For citizens, interoperability means they can access, provide and utilize government information using the IT solutions of their choice, without being stymied by closed, proprietary hardware or software solutions that do not support open standards. See IBM paper “Open Standards, Open Source, Interoperability and Government Policy”, above, footnote 31.
36 See Rambus, above, footnote 11.
37 It has been argued that injunctions should be allowed in standards context subject only to the criteria of abusive litigation, which would be the case if the proceedings cannot be regarded as an attempt to enforce legitimate rights but only serve to harass and if they are part of a framework of a plan to eliminate the competition (ITT/Promedia, [1998] ECR II-2937). But that ignores the crucial element distinguishing standard setting from a normal situation, namely, that the IPR owners have promised to license on FRAND terms, the standards organization has relied on it leading to an agreement to limit inter-technology competition that would otherwise have existed, and the industry has relied on it by making investments in innovation. Having made such a promise and obtained monopoly as a result, it should be an abuse of dominance to seek injunctive relief to extract royalties higher than those that would have pertained in ex ante inter-technology competition.

The reasonable-royalty floor for patent damages is designed to compensate a patent owner for losses it sustained as a result of infringement, not to punish or deter infringement or even to deprive an efficient infringer of all of the profits from that infringement. But the way reasonable royalties are calculated, particularly for component inventions, has made them into a tool for patentees to capture more than their fair share of a defendant’s profit margins. […] damages reform must be coupled with a solution to the holdup problems created by injunctions. […] holdup problems in patent cases can be quite significant, but that a relatively simple step—a stay of injunctive relief sufficient to allow the infringer to design around the patent if it can in cases involving reasonable royalties but not lost profits—would significantly reduce that problem”).

43 OFE Speech: “If we are to include proprietary technology in a standard, then ex ante disclosure [of essential patents and maximum royalty rates] may help those involved make a properly informed decision. Competition law should not stand in the way.”
44 Competition law may be powerless to block strategic patent acquisitions or swap arrangements of this kind, if the transactions do not meet the turnover thresholds for merger control. Qualcomm’s acquisition of Flarion’s IPR portfolio is an example.

46 “The return is NOT necessarily about royalties. The return may be that a product that includes the standard as part of it will do better in the marketplace because of the broader adoption of the baseline technology as a standard. The return might be in improved interoperability of a given product or service due to the adoption of that standard. There are competitive reasons for contributions – the hope may be to displace a competitor who is using a non-standardized solution” (J. Matusow, “Balance of Contributors & Implementers”, August 2, 2009, http://blogs.msdn.com/jasonmatusow/archive/2009/08/02/balance-of-contributors-implementers-a-blog-answer-to-rick-jelliffe-s-post.aspxhttp://blogs.msdn.com/jasonmatusow/archive/2009/08/02/balance-of-contributors-implementers-a-blog-answer-to-rick-jelliffe-s-post.aspx ).

49 Cf. Motorola v Rockwell int’l Corp, No 95-575-SRL (D.Del 1995). This should be distinguished from the 2004 decision in Microsoft, which concerned software interoperability (see fn. 80 above), was a remedy, and where patents were not ex ante essential. In that case, the Commission appropriately distinguished between two types of “value” transferred to competitors by the compulsory license that the Commission imposed, in a way that is also relevant to standards cases. It differentiated between (a) “‘strategic value’ stemming from Microsoft’s market power”, and (b) value derived from true innovation. The former is the amount that Microsoft could extract in a hold-up of the users of its interoperability information, considering that the industry cannot avoid that information because of the need for their servers to communicate with Microsoft clients and servers on an equal footing as Microsoft’s servers. The latter is the value derived from true innovation, i.e., the ex ante incremental value (if any) over the next best alternative had there been open standardization and an auction before Microsoft became dominant in client PC operating systems and the industry was locked in. See Microsoft Commission Decision of Mar. 24, 2004, Case COMP C-3/37.792, Commission v. Microsoft Corp., 2007 OJ L 32, p.23–28, ¶ 1008. The question whether Microsoft’s penultimate royalty offer was “fair and reasonable” was addressed in Decision of the European Commission C(2008) 764 final of 27 February 2008 fixing the definitive amount of the periodic penalty payment imposed on Microsoft. This decision is subject to appeal. Case T-167/08, Microsoft v. Commission, OJ C 171/41, July 5, 2008.
50 In an “ultimatum game”, one person is asked to share a stack of money with an unknown counterpart, who can react either by agreeing (in which case the counterpart receives what was offered, and the offeror keeps the rest) or by vetoing (in which case neither party receives anything). The “subgame perfect Nash equilibrium” (the optimal rational outcome) is that the first moving licensor (the offeror) receives close to monopoly rent and the remaining licensors and licensees (the offerees) receive just enough not to turn them away from licensing and implementing. Experimental game theory indicates, however, that most people do not consider the purely rational optimal outcome “fair and reasonable”. Ordinary individuals playing ultimatum games tend to share more than the rational minimum with their counterpart. This is known as “iniquity aversion.” Cf. for instance A. A. Stanton, “Evolving Economics: A Synthesis”, April 26, 2006, available at http://mpra.ub.uni-muenchen.de/2369/http://mpra.ub.uni-muenchen.de/2369/ . These studies are relevant, because they gives an indication of what reasonable participants in standards bodies (who are not economists, but normal individuals) in fact expect from each other when agreeing on FRAND licensing. See also “Standards, IP and Competition: De Aequitate Non Est Disputandum?”, Helsinki, October 7, 2009, available at http://www.iprinfo.com/tiedostot/Dolmans.pdfhttp://www.iprinfo.com/tiedostot/Dolmans.pdf .
51 If all licensees face higher royalties, all would pass them on 100% to consumers. Even if only patent-poor licensees paid high royalties (with patent rich licensees negotiating a royalty reduction for a cross-license), they would still have the incentive to pass these on to consumers, and patent-rich licensees would likely respond by raising their prices as they face less competitive pressure. Economic analysis indicates, therefore, that consumers suffer either way.
52 D Swanson and W Baumol, “Reasonable and Non-discriminatory (RAND) Royalties, Standards Selection, and Control of Market Power” (2005) 73 Antitrust Law Journal 7. Quoting Swanson and Baumol, the US FTC held in Rambus that a reasonable royalty “is or approximates the outcome of an auction-like process appropriately designed to take lawful advantage of the state of competition existing ex ante […] between and among available IP options.” In the Matter of Rambus Inc., FTC Docket No. 9302, Opinion of the Commission on Remedy, February 5, 2007, at 17. For further refinements, see also S. Besen and R Levinson, “Standards, Intellectual Property Disclosure, and Patent Royalties After Rambus”, 10 N.C.

53 See United Brands v. Commission, [1978] ECR 207 and subsequent cases on excessive pricing. A Shapley value analysis describes a way to fairly allocate gains derived from cooperation among several actors. See http://en.wikipedia.org/wiki/Shapley_valuehttp://en.wikipedia.org/wiki/Shapley_value . Honesty dictates that I admit to not fully grasping the mathematics, but the upshot is that each player obtains a share of the gains that is roughly proportionate to the relative value of his or her contribution. If one player has found a right hand glove and a second player has found a left hand glove, and the goal is to create a pair that can be sold for 6 Euro, both share the revenues 50/50. If two players have found right hand gloves and a third player has found a left hand glove, and the goal is to create a pair that can be sold for 6 Euro, the third player gets 2/3 of the revenues (4 Euro), whereas the first or second player receive 1/6 (1 Euro). (The consumer presumably receives a 1 Euro discount, benefiting from competition between players 1 and 2.) In an ultimatum game, the hard-nosed optimal rational outcome would be for the third player to offer marginal cost + 1 cent to each of players 1 and 2, allowing the third player to keep 5.99 Euro for himself (since they found the gloves and have no marginal costs). It’s rational, but is it fair? Interestingly, it appears that the outcome of a one-shot experimental ultimatum game played by Western players would in most cases also result in player 3 receiving 2/3 (4 Euro) and leaving 1/3 (2 Euro) to player 1 and/or 2.
54 R. Goldscheider, New Companion to Licensing Negotiations: Licensing Law Handbook ¶ 7.02[8][b] (2003–2004 ed.). In determining the final percentage, adjustments should also be made for the enforceability and essentiality of the patents, the geographic scope of various patents and their remaining life, the costs of complementary technology needed, the value conveyed by the patents compared to the next best ex ante alternative, the risk borne and investments made by the licensee relative to the costs and risks borne by the licensor, the volume of sales expected in the market, and so forth. It should be adjusted downwards for instance, in situations where the licensees take more than the usual risk, or where there were adequate alternatives for the patents in question.

57 See also Korean FTC Press Release “KFTC took corrective measures against Qualcomm for abusing its monopoly market status in modem chip market; Imposition of fine and issuance of corrective order for discriminative royalty rates, conditional rebates, etc”, July 23, 2009. The EC Commission’s case-law and practice in the context of essential facilities suggests that licensors of patents that are essential for compliance with a de jure or de facto mandatory standard should ensure separate accounting for their downstream manufacturing of standard-compliant products, so as to be able to demonstrate that they do not give competitive advantages to their own manufacturing divisions that they withhold from outsiders. The usual objection under US law against price squeeze analysis (that if the supplier has no duty to supply, it cannot have a duty to avoid price squeezing) does not apply where the IP owner promised to license on RAND terms.

63 See also European Commission, White Paper, Modernising ICT Standardisation in the EU - The Way Forward, COM(2009) 324 final, July 3, 2009, p. 6-7. The requirement in procurement rules, that requests for proposals should refer to European standards where available, serves to ensure maximum consumer choice and dynamic competition, and these goals could be subverted if closed or proprietary standards qualified for preferential treatment under procurement rules.
64It is unclear whether there is a legal basis in consumer protection provisions of the Treaties, and adoption and implementation of appropriate instruments will take years and be controversial, if it can ever be achieved. It may be possible to amend the Standardization Directive to insist on open standards for European standard setting (Directive 98/34/EC of the European Parliament and of the Council of 22 June 1998, laying down a procedure for the provision of information in the field of technical standards and regulations and of rules on Information Society services (OJ L 204 of 21.07.1998), as amended by Directive 98/48/EC (OJ L 217 of 05.08.1998), but even that will be subject to controversy and intense lobbying by firms that benefit from hold-up practices. Fostering open standard setting under Articles 101(3) and 102 TFEU and the Guidelines for Horizontal Agreements seems the most efficient solution, certainly in the short term.
