Introduction
In principle, the patent system is equally accessible to all inventors.Footnote 1 Big corporations, small start-ups, and individuals all have their patent applications scrutinized by the same patent office. If granted, their patents receive the same protection, duration, and remedies.Footnote 2 This equality principle serves an important purpose. It guarantees a neutral position of patent law and pledges equal opportunity to all inventions to win in the marketplace.Footnote 3 Theoretically, equality serves another vital objective: to ensure diversity of inventions.Footnote 4 It does so by giving new and small inventors the same treatment as experienced and well-known inventors and not granting an advantage to inventors who may be perceived as having a higher chance of success.
However, the patent system is not equally accessible to all. Some actors are more likely than others to file for patents and have their patents granted.Footnote 5 Thus, patents are more handily granted to men over women, whites over minorities, and big companies over start-up firms.Footnote 6 Granted, this reality is largely a product of the broader phenomenon of inequality in other spaces, such as academia and entrepreneurship, rather than a feature of the patent system per se.Footnote 7 Yet, in this chapter, I propose that a decentralized design of the patent system, particularly the patent record, can mitigate this inequality. Although this chapter focuses on the patent system in the United States, much of the analysis can apply to patent systems worldwide.
The extant patent system in the United States is centralized almost from end to end. The U.S. Patent and Trademark Office (PTO) is responsible for examining patent applications, publishing the granted patents, and increasingly managing postexamination proceedings.Footnote 8 For a number of reasons, the centralization of all of these functions within the PTO has adverse effects on equality. First, the current system involves high entry costs and requires particular know-how that benefits repeat players and highly capitalized inventors. Second, centralization requires a single agency to examine the entire pool of patent applications. The immense quantity of patent applications compels examiners to use decision shortcuts and proxies. It should come as no surprise that these shortcuts work in favor of big and repeat players and to the disadvantage of traditionally underrepresented groups in the patent system. Third, the current system grants many unmerited patents, mainly to big corporations.Footnote 9 These patents create barriers to entry for newcomers. Finally, the current system features a limited patent record – a static registry that holds only basic information about inventions. Acquiring updated and relevant information regarding the technological, legal, or commercial status of inventions is costly. The cost barrier places underfunded inventors at a disadvantage and at risk of falling victim to patent trolls.Footnote 10
In a recent work, I considered an idea to decentralize the patent system.Footnote 11 In particular, I proposed to open the public record to input by market and state actors during the examination process and throughout the lifetime of the patent, using blockchain or other technology. During the examination period, third parties could submit prior art and weigh in on obviousness. Following the patent issuance, patentees would be able to register updates to the patent, the underlying invention, or products that rely on it. They will also be able to offer licenses via smart contracts or otherwise. The court system would add to the record cases that pertain to the patent. That article argued that decentralization could improve the productivity and effectiveness of the patent system and accelerate the introduction of inventions to the market.Footnote 12
In this chapter, I explore the possibility that decentralization could boost equality in the system by removing access barriers and turning the patent record into an effective platform to learn about inventions and commercialize them affordably. The first part of this chapter discusses the principle of equality in patent law in theory and practice. The second part explores the distributive problems that the current system entails and the future improvements for equality with the shift to a decentralized architecture. A short conclusion ensues.
9.1 Equal Access to the Patent System
In theory, equal access is a key feature of the patent system.Footnote 13 With few exceptions, patent law abides by a strict nondiscrimination principle.Footnote 14 Neither the examination criteria nor the rights attached to patents grant favorable treatment to inventors based on their experience, size, financial status, or the likelihood that the invention would be valid as a patent, manufactured or sold.Footnote 15
Nondiscrimination is a crucial principle. It ensures that all inventors, including small entities and members of marginalized communities, have an equal chance to protect their inventions. Consequently, under the assumption that patents incentivize invention, the equality principle augments everyone’s incentives to invent.Footnote 16 Beyond its distributive value, the equality promise is designed to increase innovation gains by diversifying the inventive base.Footnote 17 A broad pool of inventors can yield a diversity of products, markets, and processes because different founders see different innovation needs.Footnote 18 In particular, inventors from underrepresented groups can tackle issues that sit in the blind spots of others or address well-known problems with more inclusive solutions.Footnote 19 Access of small technology companies to the patent system bears particular importance.Footnote 20 Small entities are both disproportionately innovative and crucially dependent on patents to secure funding and market entry.Footnote 21 Yet small entities are less likely to make use of the patent system.Footnote 22 Guaranteeing the access of small entities to the patent system thus best furthers the objective of the patent system to promote innovation.Footnote 23
Despite the significance of the equality principle, equal access to the patent system remains largely theoretical. As Peter Lee put it, on the ground, “the U.S. patent system has become highly corporatized and concentrated.”Footnote 24 Indeed, most patents are issued to large corporations,Footnote 25 with some industries featuring extreme concentration.Footnote 26 Inequality overwhelmingly persists among individual inventors as well. Women are issued around 20 percent of patents, and only 8 percent of patents feature women as the primary inventor.Footnote 27 The rate of minority inventorship is somewhat under-researched,Footnote 28 but indications are that this rate is very low, particularly among Blacks.Footnote 29 Generally, as Dan Burk and Mark Lemley observe, “even those [patents] granted to individuals and small corporations are often incubated in large research universities.”Footnote 30
Several reasons for the unequal distribution of patents have nothing to do with the patent system per se. Social, economic, and other pressures force some groups out of the innovation economy and other inventive spaces.Footnote 31 Yet part of the problem, and perhaps partial solutions, may lie in issues pertaining to the patent system. The next part discusses such issues and explores the possibility that decentralizing the patent system can improve equality.
9.2 A Decentralized Patent System
Currently, the patent system features a rigorously centralized structure. The PTO examines patent applications, publishes the granted patents to the public, and increasingly manages postexamination proceedings.Footnote 32 While surely unintended, the centralized structure of the patent system jeopardizes equality in three main ways. First, a central examination entity involves high entry costs and requires particular know-how, including institutional knowledge. High entry costs work to the detriment of new and under-resourced inventors.Footnote 33 Second, centralization congests the system and induces patent examiners to use decision shortcuts and proxies that favor strong and repeat players. Third, the current system over-grants patents, mainly to big corporations, and these patents form barriers to entry for newcomers. Finally, the current system features an inadequate patent record that lacks vital information about inventions and frustrates the use of that record as a source for consultation in the invention ecosystem. Acquiring such information elsewhere is cost-prohibitive for small inventors, but operating without it exposes them to market and legal risks. The thesis advanced in this chapter is that decentralizing some of the PTO’s functions can effectively address these concerns and boost equality.
9.2.1 The Problems in a Centralized Patent Regime
The most apparent distributive concern in the patent system involves high entry costs.Footnote 34 Patent prosecution has become increasingly expensive, partially due to the prolonged processes at the PTO, which compound legal and other expenses, and partly because the complexity of these processes requires expensive professionals to navigate them.Footnote 35 Patent prosecution may be even costlier for small inventors, who, among other things, do not have in-house patent attorneys.Footnote 36
The financial barrier to the patent system prompted Congress to lower the filing fees for small firms and micro-entities through the Leahy-Smith America Invents Act.Footnote 37 This statute also entitles small entities and independent and unrepresented inventors to technical, pro bono, and pro se assistance.Footnote 38 Despite such measures, inequality seems to worsen with time.Footnote 39 The reduced fees have not moved the needle, most likely because these fees are negligible in the overall expenses of patent prosecution. Also, the rate of abandoned applications is more than twofold for pro se applicants than for represented applicants.Footnote 40
High entry costs confine small companies and individuals more than well-resourced corporations. The most obvious result of costly patent prosecution is that small inventors give up on patents. While avoiding patenting may be rational for small entities,Footnote 41 it exposes their inventions to copying and may yield an inferior position in the marketplace.Footnote 42 Indeed, the rise of trade secrets protection provides alternative, cheaper protection that often suits better the financial capabilities, focus, and business of small entities and individual inventors.Footnote 43 Yet, if patents exist as a tool to generate an incentive to create, then the exclusion of certain groups from patenting adversely affects their incentives to invent.Footnote 44 But high costs can be even more devastating; small inventors depend on investments, but investors are reluctant to fund patent prosecution and often delay investments until patents are secured.Footnote 45 Consequently, inventors may be forced to relinquish their ventures altogether or settle for lower valuations than their invention is worth.Footnote 46
Consider now the backlog of the patent system. Currently, the PTO examines all patent applications alone, generating severe delays.Footnote 47 A high pendency rate has a differential effect on the market. For small players, pendency shrinks the duration and thus the value of patent protection.Footnote 48 Big players, in contrast, can make lemonade out of the long application process lemon. Such players can file numerous broad patents, including for embryonic ideas that did not go through full development or feasibility testing. They can then strategically use the “patent pending” status of their applications to persuade others to back away from their asserted territory during the long examination period, even if the application would eventually be denied or reduced in scope.Footnote 49
The backlog at the PTO potentially affects the incentives of examiners as well.Footnote 50 While probably unintended, proxies for validity – such as inventors’ names, former acquaintance with the representing agent, and institutional affiliation – are almost inevitable considering the severe examination backlog at the PTO and the time constraints imposed on examiners.Footnote 51 These biases are compounded by the notorious public choice problems at the PTO that further the interests of large corporate patent filers and other repeat players at the expense of smaller inventors.Footnote 52 Institutional capture easily penetrates into the individual level of examiners, who may be contemplating their next career step as patent prosecutors or major patent holders.Footnote 53
The third challenge that the extant regime poses to equality concerns the prevalence of low-quality patents. The issue of patent quality has long troubled patent scholars.Footnote 54 From the equality prism, the concern is that the PTO is biased toward granting patents, de facto disadvantaging small inventors who file fewer patents and must penetrate a dense screen of patents to function. Remarkably, Alberto Galasso and Mark Schankerman find that innovation by small firms is often triggered by invalidating large firms’ patents, suggesting that those patents thwart innovative efforts.Footnote 55
A key reason for the over-grant bias is that the PTO has limited access to the information and proficiency required to disqualify patents and insufficient time to acquire such information and proficiency.Footnote 56 Indeed, patent applications must be granted absent reasons to deny them.Footnote 57 But assessing applications’ novelty and nonobviousness typically requires highly contextual, fact-intensive, industry-specific information (to disqualify patents based on a lack of novelty) and very specific expertise (to deny patents based on their obviousness).Footnote 58 Such knowledge is naturally dispersed in society rather than concentrated in one agency.Footnote 59
What is more, the incentives of the PTO are set up to make it an ineffective gatekeeper for patent quality. The PTO is largely self-funded by patentees’ fees, generating an institutional disincentive to reject patents.Footnote 60 Studies even indicate that the PTO grants more patents in areas where fees are higher.Footnote 61 To avoid time-consuming disputes, a swamped PTO is also better off granting borderline patents, particularly to applicants who will likely challenge rejections.Footnote 62
Finally, another way that a centralized patent system contributes to inequality concerns information problems in the patent record. Naturally, a PTO-operated patent record can only include information that the PTO possesses at the time of publication.Footnote 63 But such a record is gravely deficient. The current record lacks information about the background science of the invention and any developments since it was filed. Neither does it include information relating to litigations or transactions, such as available licenses and prices.Footnote 64 However, its immense value, including robust information in the patent record, is unrealistic under a centralized model. The PTO has no access to the information that is most relevant to make the record useful for the inventive community. Much of this information is also dynamic and is changing over time. A central agency cannot realistically be responsible for collecting and registering updates to the record.
An inhibited record has distributive effects. Highly capitalized inventors can overcome information deficiencies by investing in other methods to acquire information, which is cost-prohibitive for small players.Footnote 65 But running an underinformed business involves market and legal risks. The main risk concerns exposure to “patent trolls” – nonpracticing entities who accumulate vast portfolios of dubious patents and use them for strike suits against innocent infringers.Footnote 66
These problems did not go unnoticed, and Congress, courts, and the PTO have attempted to tackle some of them.Footnote 67 Yet, high costs, congestion, information problems, and capture are inherent to a centralized PTO and will render any solution that maintains the current structure partial at best. Next, I explore whether decentralizing some PTO functions can provide a better way forward.
9.2.2 Can Decentralization Provide a Solution?
Imagine that the power to write information into the record was not exclusive to the PTO but distributed among state and market actors. The patent record would be built on a blockchain or another platform that enables the autonomous sharing of information by authorized parties.Footnote 68 Such parties would be able, and in some cases obliged, to update the record with relevant information during the examination process and throughout the duration of the patent. Under a decentralized model, third parties and scientists could submit prior art and weigh in on obviousness for the use of examiners during the examination period. After patents are issued, patentees could include in the record commercial information, such as licensing and pricing information, and even plug-in smart contracts. Courts would list decisions and outstanding cases that pertain to the patents. These updates would inform the patent community whether patent claims are in question, whether the patent holder is prone to litigation, and other useful information that is costly to obtain under the extant regime. The PTO would be responsible for reviewing the patent record and fixing errors.
In my previous work, I tackled the practical aspects of this proposal and the related concerns.Footnote 69 The main concern revolves around whether there are adequate incentives for market players to contribute to a decentralized record. This is a critical point. After all, a functioning patent record is a public good. Without private incentives to participate in it, the record would be unable to achieve its goals.
The first answer to that concern is that some contributions to the decentralized record would be automatic or mandatory and would be independent of the participants’ goodwill. For example, patent applications would be fully published, with automatic references to similar materials on the record;Footnote 70 information about litigations would be added by courts as created, and patentees would be obliged to maintain the accuracy of the information on available licenses. This information would already be a substantial improvement over the current regime.
Consider now the incentives for market players to participate in the system voluntarily. It is relatively easy to see the incentives for patentees to add licensing information to the record. Adding such information would enable patentees to commercialize their inventions without much effort. Some patentees, such as big pharmaceutical companies, may prefer to continue licensing their patents individually.Footnote 71 Yet, this functionality can be extremely valuable for small companies or individual patentees that do not have resources to negotiate each license individually, as well as for owners of vast patent portfolios who can build a cost-effective licensing model.
How about the interests of third parties to contribute information to the record? During the examination process, firms would be incentivized to question the validity of patents that would curb their free operations. From their point of view, this mechanism would be a cheaper, easier way to battle a patent than postreview examination, let alone litigation.Footnote 72 The concern may be that such parties would be too eager to provide invalidating information in a way that would jeopardize the efficiency of the system. My previous work addressed this concern.Footnote 73
Other contributors, such as academics or scientists, may be motivated to participate by other considerations, such as reputation or exposure to new information in their field. Volunteer reviewers are the regular case in many academic frameworks, such as reviews of submissions to scientific journals and grants. It would thus not be surprising to see scientists weigh in on an invention in their field.Footnote 74 At the postexamination stage, technology firms and scientists would be incentivized to update and consult the record as an affordable mechanism to avoid infringements, as well as to learn of new inventions and form collaborations.
Decentralizing the patent record could transform the record from a static database that includes basic filing information that is barely used in the industry into an up-to-date platform that forms a central tool in the innovation economy. This strategy can potentially improve equality in the patent system in three main ways. First, it would tackle distributive concerns in the patent examination process. Second, it would protect small inventors from information problems. Third, it would boost the commercialization of patents, particularly for small inventors.
Consider first how decentralization can cure distributive harms in the examination process. As discussed, the patent prosecution process is done ex parte under the current regime. However, market actors hold superior information, such as knowledge of instances where the invention was offered for sale or disclosed publicly.Footnote 75 The PTO alone is entrusted with raising arguments to reject the patent or narrow down its claims.Footnote 76 It performs this task in a suboptimal manner, under time and knowledge constraints.Footnote 77 Decentralization would make invalidating information handily available to examiners and reduce the rate of low-quality patents, which form entry barriers for small players. A broader information basis would also save examiners search time and attenuate their need to rely on proxies, which have discriminatory effects.
Even greater equality can be found in the postexamination period. An updated patent record would provide a cost-effective means to gain useful technological, transactional, and legal information throughout the duration of the patents. Making robust information available to small players levels the playing field between them and big players, rendering it less likely that entrenched firms could learn about patents and new players in their field more than start-up ventures.Footnote 78 Tackling information problems would also enable innovators to avoid infringements, thus battling patent strike suits, which can devastate small entities.
Finally, decentralization of the record would introduce a platform to commercialize inventions globally. Patentees could list licensing options, potential use cases, and prices on the patent record. Once the record contains such robust transactional information, cooperation with commercial bodies to bring the invention to the market is much more likely.Footnote 79 A distributed registry could also enable functionality not existing today, such as plugging in smart contracts and allowing third parties to act on available licenses automatically.Footnote 80 This functionality can be extremely valuable for small companies or individual patentees that do not have resources to negotiate each license individually.
The benefit of this policy is twofold. First and foremost, the dynamic record can further the goal of the patent system – to accelerate the path of innovation to the market.Footnote 81 Second, improved commercialization would have a dynamic effect. It could spur innovation and patenting because patents would become an effective reward for inventors.Footnote 82
Conclusion
The technological ability to decentralize the power to write into the patent record presents intriguing opportunities to generate a patent system that is more inclusive and diverse and to address the pressing issues of equality in the patent system.
An intriguing question can arise in this context: Considering the pledged efficiency of a blockchain-based database for inventions, why has the market not stepped in to create such a registration itself? The answer to this question is that some trading platforms between inventors and licensees exist worldwide.Footnote 83 Yet, without regulation, these platforms are underdeveloped. The first reason is that the market does not internalize the distributive concerns discussed in this chapter, and therefore market-based registries may not develop as efficiently as they should. In this vein, a second issue with market initiatives concerns information and collective action problems. Too many actors from various industries and jurisdictions need to join together to generate an effective patent record on the free market.
Yet the most fundamental reason is that it is simply more efficient to decentralize the state-run patent registry than to create a new registry, especially when distributive concerns are considered. The patent registry is a legal creature. It is set by the law and operates under the controlling statutes in each country. Thus, market initiatives cannot replace the existing record, but they can rather duplicate the platform and add to it. This reality harms efficiency and generates distributive harm by adding another registry and multiplying registration costs. At the end of the day, while a market-based scheme has its advantages, it would be more efficient to channel the resources and efforts that are already being made for patent registration to a registry that is valuable to the market.
