Document:
The justification of applying the exhaustion doctrine to intangible copies of copyright protected works is widely discussed in scholarly circles. The discussion mainly concerns the relevant provisions of the international treaties and rationale of the exhaustion doctrine under EU law. However, little attention is paid to the question regarding how the potential outcome is comparable to the one exhaustion brings in the analogue world. This article goes beyond the theoretical legal discussion and presents a case study of e-books disseminated through Amazon. The authors analyse the legal, technological and organisational challenges of creating a secondary market. In line with the identified challenges, this paper presents two scenarios based on the particular circumstances observed at the Amazon distribution solutions. The first presupposes the creation of a limited secondary market within Amazon. The second enables a broad secondary market of e-books purchased through different channels, including Amazon. The two scenarios could potentially be combined to achieve a secondary market of e-books in a controlled manner. This would allow vendors to keep nearly the same degree of control over distributed copies while serving consumer interests and creating the Digital Single Market.
The modern copyright law serves multiple objectives. It aims to protect the author’s interests, facilitate dissemination of knowledge, and support societal development. As copyright protection evolved and exclusive rights extended in their scope, the need to balance them with the interests of third parties and society in general arose. The exhaustion doctrine is one of the examples where the introduction of a broad exclusive right of a copyright holder is in most cases accompanied by the principle of exhaustion of the right upon meeting certain conditions.
On the one hand, copyright provides a monopoly, which restricts competition and the circulation of goods. The European Single Market is based on the free movement of goods,  and thus, it is dependent on the restrictions imposed on the exclusive rights. While the Single Market is a reality for physical goods, the Digital Single Market is in its infancy. Therefore, the establishment of this market is a priority task for the European Commission according to the Digital Single Market Strategy.  It aims, inter alia, to provide better access for consumers and businesses to online goods and services across Europe by rapid removal of the key differences between online and offline worlds.
The article concentrates on the free movement of digital goods. In particular, it focuses on the secondary market of e-books, since it constitutes a widespread basis for comparison of tangible and intangible goods. The authors rely on the EU acquis and use the e-books disseminated through Amazon as an example. The goal of the article is to identify the main challenges to the Digital Single Market of e-books (based on the case of Amazon) and suggest the possible steps to overcome them by combining legal, organisational and technological measures. This paper sets out to argue that the challenges relating to the resale of e-books can be overcome only if various legal, technological and organisational aspects are taken into account.
The article is organised into four main sections. In the first section, the authors address the nature of the exhaustion principle and its role in facilitating the EU Single Market. The second section provides an overview of the dissemination model for e-books adopted by Amazon. These serve as a basis for the analysis of a number of legal, technological and organisational challenges of reselling e-books, discussed in the third section. The fourth section identifies the possible scenarios for enabling a secondary market for e-books by combining legal and non-legal measures.
Consequently, the exhaustion principle restricting the right of distribution contributes to the removal of barriers to the EU Single Market indicating free movement of goods within its borders. In the context of literary works protected by copyright, free movement also facilitates the dissemination of knowledge and culture within the Community. Goods distributed in one Member State can reach consumers situated in another Member State. This also allows lowering of the price, which generally widens the market and makes works affordable to consumers with high elasticity of demand.
The situation is, however, different for intangible goods. Firstly, intangible goods are often treated differently from their tangible counterparts, also in the fields other than copyright.  Secondly, in the absence of legal certainty about the application of the exhaustion doctrine to copies distributed without a tangible medium, there is no apparent secondary market for intangible goods. Thirdly, the nature of intangible goods allows controlling dissemination of copies by technical protection measures  irrespective of the applicability of the exhaustion doctrine.
The next part of this paper deals with the dissemination of a particular type of an intangible good – an e-book. Above all, it addresses e-books distributed by Amazon. It also considers the way in which specific conditions influence the possibility of achieving EEA-wide secondary market.
Amazon Kindle Store  facilitates the distribution of e-books published both by professional publishers and by individuals resulting in a variety of offerings. In this paper, whenever references are made to the procedure of placing an e-book on a marketplace, dissemination of e-books by self-publishers through Kindle Direct Publishing (KDP) service is meant. A publisher can choose whether to make an item available on particular marketplace(s) only, to offer it world-wide, or both. E-books can be put on a market in different languages, although there is a conclusive list of supported languages for the global marketplace if an e-book is published by a self-publisher through KDP. As a result, e-books written in Cyrillic are accessible on the Kindle store, but offered only by recognised publishers.
E-books are sold to individual users, one copy per Kindle account, with a possibility to view its content simultaneously on multiple devices associated with an account.  However, the bulk sale of e-books is a recently introduced option, which is currently only available in the US.  Amazon’s service Whispercast allows customers to purchase multiple copies of an e-book at the same time and their subsequent distribution between individual Kindle accounts.  E-books purchased through Whispercast can be used for educational purposes or also within business entities, as the platform allows distribution of own content along with purchased e-books.
As e-books are not tied to a specific device, but to a Kindle user account, its content can be read simultaneously from different devices as long as they are connected to the same account. There are, however, certain restrictions – a single e-book cannot be loaded into more than 6 devices at the same time. DRM also does not allow access to an e-book other than through the Kindle application, thus preventing manipulating a copy, including its transfer. One-time lending option of 14 days is available if authorised by the publisher.  Lending an e-book makes it unusable for the consumer who purchased it until it’s returned automatically within 14 days, so a copy is available for one account at the time.
In conclusion, Amazon maintains a highly centralised system for the distribution of e-books supplied by professional and self-publishers. The control over copies is exercised to the extent that one copy is associated with one account, but can be read from multiple devices as long as they belong to the same account. Apart from reading, a consumer cannot dispose of a purchased copy as it can only be accessed through special software and may not be transferred to a different account, except for the purpose of a one-time lending option. This does not constitute a transfer in a technical sense as the content is synchronised to a device associated with a different account and becomes unavailable for the primary one. The next section examines how the conditions of dissemination directly challenge the Digital Single Market.
Admittedly, the dissemination of e-books is rather different from that of printed ones. Since the exhaustion doctrine was formulated and enacted in legal provisions at a time when the market consisted mainly of tangible goods and the dissemination of copyright protected works required a separate tangible medium,  there are challenges to applying its logic to copies lacking durable medium.  Those challenges are of legal, technological, and organisational character. The emergence of a secondary market is not self-evident even if we assume that the exhaustion doctrine applies to copies lacking tangible support in the same way it does to tangible copies. For a secondary market to exist, consumers must be able to enter the market, offer their copies for sale, and effectively transfer them. This part of the paper deals with the variety of challenges facing a secondary market.
One of the cornerstones of the exhaustion doctrine, and copyright in general, is the concept of a copy. According to Article 4(2) of the Copyright Directive, a copyright holder’s right to control the distribution of a copy of a work or its original is exhausted upon a sale of that copy. Accordingly, a copyright holder’s right is exhausted only in regard to a specific copy distributed by sale or otherwise and not the work in general. Creation of copies is at the heart of Internet and network transmissions. In principle, every act of reproduction of a copyright protected work is subject to the right holder’s authorisation. Whereas the problem of an overly broad interpretation of the reproduction right was to a certain extent tackled by providing an exception for reproduction taking place in the course of digital transmission,  it is not the case for the concept of a copy as a whole.
A digital copy lacks most of the features of a tangible medium which for a long time was seen as the only means to distribute a work. First of all, it lacks clear boundaries. An intangible copy is often perceived as a file of certain format which, with the use of a particular device and software, allows end-users to consume a work. However, a file is simply an identifier of a place on a hard-drive where specific bytes containing information in a binary code are stored. There might be multiple identifiers (files) pointing to the same sequence of bytes, as there might be links across the computer file system to the same location on a hard-drive. Thus, instead of associating an intangible copy with a file, it would be more logical to tie it to the bytes instead. This approach would, however, be undesirable as it would require technical knowledge to assess whether multiple copies exist on a same drive and whether a copy was manipulated.
The notion of a digital copy warrants further research. The CJEU in the UsedSoft case partially addressed the notion of a copy and how it translates into the digital environment. UsedSoft resold software licences without providing a copy as such; the subsequent acquirer downloaded it from the vendor’s webpage and used it with the acquired licence. Hence, the obtained copy was not technically the copy originally acquired. However, for the purpose of applying the exhaustion principle under the Software Directive, it was sufficient that the subsequent acquirer obtained a licence and downloaded a copy from the vendor’s webpage. The approach of separating a copy from an acquired licence would indeed be helpful for the secondary market of e-books. The recent CJEU judgment in Vasiļevičs  suggests that it is indeed the way to go, as it precludes the resale of backup copies of software. Furthermore, it is in breach of the vendor’s copyright to upload backup copies for resale, but not to “sell” licence rights to a copy and direct the acquirer to the vendor’s webpage to download a copy in line with the UsedSoft.
Another point of concern is the territoriality of copyright and exhaustion doctrine. As the Copyright Directive establishes regional EEA-wide exhaustion, the distribution right can only be exhausted in respect of the copies which are put into circulation with the right holder’s authorisation within the EEA. Accordingly, it is necessary to keep track of the initial transaction of sale to determine whether a particular copy can be put on a secondary market. Addressing this aspect requires consideration of a number of legal, technical and organisational measures. From the legal perspective, it might be worth to evaluate the necessity of maintaining regional exhaustion for intangible goods such as e-books. Given the absence of an agreement on justifiability of maintaining a regional exhaustion, it might be insightful to study the impact of international exhaustion on a potential secondary market of intangible copies. There may be a case for promoting greater cultural diversity within the EEA by allowing the import of e-books purchased outside its borders, which are otherwise not accessible on the EU market.
It follows that the key legal issues for a secondary market of e-books are dependent on the legal interpretation, creation of the EU-wide legal concepts and policy choices. As indicated in this part, the absence of a clear position on the concept of an intangible copy is one of the main obstacles to further discussions, as manipulating such copies for the purposes of transfer to subsequent acquirers falls within the exclusive rights of right holders. The same applies to the sale or transfer of ownership requirement. Extending the UsedSoft approach - where perpetual licences were deemed to constitute a transfer of ownership - would further benefit the secondary market and eliminate uncertainties. As the CJEU rightly stated, online transmission is functionally the equivalent of supply in a tangible medium. Where the effect of such a transmission is the same as of transfer of possession over a tangible object, the form of contractual arrangements should not be decisive in determining whether a transfer of ownership occurs.
There are a few potential approaches to control access to an e-book through the DRM technologies, which take into account the geographical location along with the environmental and organisational settings. For instance, the Attribute-based access control (ABAC)  grants access to objects after assessing permission rules against the attributes of subjects and objects, operations, and the environment. The access decision depends on the comparison of the attribute values of a potential reader of an e-book to the copy itself. Another access control model - usage control model (UCON)  is based on the monitoring of the use of the resource (e.g. an e-book), which enables enforcing change of the access permissions and re-assessment of the subject’s rights, e.g. when the owner of the copy is changing. The final access decision is made by re-assessing the authorisation, obligation and condition constraints by using the specified access rights.
Another dynamic model - Risk-adaptive access control (RAdAC)  - has the property of adapting access permissions based on the continuous changes in the environment. The permission is granted after estimating the situational factors and assessing the dynamism of the environment; hence, the access permission depends heavily on the changes in the environment. This is especially relevant for the digital right management of e-books when the change in the possession of a copy is taken into account. The use of different access control schemes could potentially help manage the access rights when the owner of a copy, territorial access, or any other environmental properties are changing. However, determining properties of the environment, user, operational and technological components remains a development challenge.
Although the sale of multiple copies of an e-book is not a widespread practice yet, it could gain importance in the future. Amazon Whispercast, which was briefly discussed above, allows the purchase of multiple copies of an e-book with further distribution of the copies between individual Kindle accounts. The question would be whether individuals who also possess a copy of an e-book which they were granted access to by Whispercast administrator account,  would be able to rely on the exhaustion doctrine to sell these copies, or whether it is solely the owner of a Whispercast administrator account who can resell the copies. Unlike printed books, where the owner of multiple copies loses control over the copies he sells, an administrator of Whispercast retains control and can withdraw a copy from individual accounts.
It follows firstly, that technological and organisational challenges arise mainly from the difficulties in meeting the legal criteria for copyright exhaustion to occur. Secondly, they result from the adopted business practices and technological solutions implemented to serve these practices and also to comply with the legal regulation. Accordingly, when analysing the possible scenarios to facilitate a secondary market of e-books - in this case purchased through Amazon - it is necessary to consider all the challenges collectively. As suggested in the next section, it does not seem realistic to facilitate a broad secondary market by solely imposing the exhaustion doctrine on e-books (or intangible goods in general). Therefore, also the option of a limited secondary market (within Amazon) is considered.
Amazon’s ability to manage distribution of e-books centrally is, of course, in conflict with consumer interests to dispose of a purchased copy.  Certain consumer interests are nevertheless taken into account, such as the possibility to access an e-book on multiple devices and to lend it to a friend or a family member (although it is as a time-limited and one-time option). The centralised system is even more controversial when it comes to the disposal of a copy for the purposes of entering a secondary market. This disadvantage, however, can be turned into an advantage for both sides if Amazon were to take an active role in enabling a secondary market.
Making it technically possible to move purchases in-between user accounts would provide consumers with an option to dispose of a copy (albeit limited to potential acquirers in possession of a Kindle user account) and also provide Amazon with a certain degree of control, particularly when it comes to enforcing the applied DRM measures. What is required to this end, is to provide a consumer (in possession of a Kindle user account) with an option to transfer his or her purchase to a different consumer (with a Kindle user account). The consequence of this would be that the content of an e-book is synchronised to the devices associated with the acquirer’s account and that an e-book is delisted from the previous owner’s account, resulting in synchronised content being removed from respective devices.
When facing territoriality of exhaustion, it would also be necessary to verify for each copy whether the rights are actually exhausted. Correspondingly, one needs to implement a check whether a copy was placed on a market within the EEA, and, if yes, then the transfer should be permissible. To determine which transactions took place within the EEA, the most straightforward solution would be to filter out transactions from the 6 dedicated marketplaces of the EU Member States. If this option is chosen, purchases by consumers situated in the EU but without access to any of the dedicated marketplaces within the EU, would be out of the scope of a secondary market. This should most certainly be prevented. If the exhaustion principle is to remain EEA-wide, there is a need to classify transactions not based on whether they took place on a dedicated marketplace, but to filter out purchases made by the residents of the EU Member States on all the marketplaces. This second option would also ensure that copies purchased by residents of 10 EU Member States having access to dedicated marketplaces would be eligible for entering a secondary market regardless of whether they were purchased on a dedicated marketplace or on a global one.
The scenario described above is not a new one for Amazon. In 2009, the company filed an application and in 2013 was granted a patent in the US for a secondary market for digital objects.  According to the patent description, the system allows storing digital objects purchased from original vendors in a secure personalised data store and moving objects into the other user’s data store subject to meeting certain (if any) conditions. These conditions can include one or more business rules, such as a move limit e.g. restricting the number of times an object can be moved between the users, levying a fee upon movement, etc. Accordingly, such a system is close to that proposed, as it ensures that a copy is accessible to one user account at the time and is managed centrally.
What is overlooked here is the territoriality of the exhausted rights. It, however, could be implemented technically by introducing extra business rules as a condition for system authorisation of a transfer. For instance, limits on transferability of a copy could be put in place by the copyright holder upon publishing an e-book. Nevertheless, such limits would have to be checked against the applicable legislation. By way of example, a copyright holder is not able to prevent transfer within the EU of a copy put into circulation with his authorisation in one of the Member States. That is to say, an authorisation system of this type needs to respect possible restrictions on the copyright holder’s right to control distribution of copies, as enumerated in the law.
The option described above could be the first step in enabling a fully functional secondary market of e-books. It would preserve the vendor’s ability to exercise a certain level of control over purchases and transfers, not least when it comes to the enforcement of DRM measures. This solution would require only limited legislative change as DRM would not have to be discarded or substantially altered. Amazon’s patent in the US shows that the retailer is aware of the potential emergence of a secondary market, not only a limited one, but also a broad one, where different intangible goods originating from diverse vendors are being stored in a secure location and transferred between the accounts, as it will be elaborated in the next part.
While a limited secondary market comprises e-books purchased through Amazon and transferred between the user accounts, a broad one would include copies purchased from different vendors and available for potential purchasers regardless of whether or not they are in a possession of a user account or a particular device. For e-books purchased through Amazon to be able to enter such a secondary market, it is necessary to create conditions for export of a copy from a device or Kindle application and its transfer to a different data storage (mostly over the Internet). For this reason, a copy would have to be made unusable at the time of transfer and DRM modified or abolished to allow a transfer.
Redistribution of digital content has been studied by some scholars primarily from the technical perspective. Whereas the purpose of the DRM measures is to restrict the user’s disposal of a copy and as such it conflicts with the aim of redistribution, proposals have been made on how to facilitate redistribution while preserving DRM policies.  Acknowledging the technical difficulty of securing digital content, the authors suggest focusing on the distribution of digital copies to a variety of devices instead of only custom-built compliant devices, and its subsequent controlled redistribution. This solution allows the use of watermarking for the purpose of tracing a copy; furthermore, it also allows the inclusion of a payment mechanism into a transaction, either as a direct one between the consumers, or with the involvement of a provider or even a financial institution.
The only aspect that was identified as a challenge of a legal, technological and organisational nature, and not directly addressed in the solution described above, is territoriality of the exhaustion principle. However, as technical implementations could potentially permit preservation of certain DRM policies and watermarking, it could facilitate passing on information regarding the initial transaction. Having this information stored securely along a copy, combined with mechanisms as described in the Amazon patent and allowing checks whether certain conditions were met to either confirm or deny a transfer, could serve the purpose of determining which copies can be transferred. However, there is also a need to decide on which basis transactions would be qualified as taking place within the EU/EEA. If for e-books distributed through Amazon it could be, as discussed earlier, transactions made on the dedicated marketplaces or those made by the EU or EEA residents, it is more challenging to define it for the wide array of e-book distribution channels.
Enabling a broad secondary market of e-books, which is the closest equivalent of a secondary market existing for printed books, is clearly more challenging than facilitating a limited one. However, relevant analysis indicates that such an option has been studied both from technical and business side. As a secondary market of e-books is non-existent at the moment, then following the second scenario of creation of a broad secondary market seems less realistic than starting with the first option of enabling a limited secondary market in a more controlled manner. Dividing the creation of a secondary market into stages would allow to explore any further challenges to a broad secondary market while preserving a certain degree of control by the vendors.
Technological development has heavily influenced the consumer’s habits and preferences. Whereas certain goods are only supplied as tangible ones, more and more intangible copies are being offered. It does not mean that they are independent from the material components, but it rather indicates that each copy does not require a separate tangible embodiment (e.g., paper, CD, etc.). Whereas this shift makes it convenient for consumers to access a work, it can also be a disadvantage because goods tend to be differentiated for a number of purposes depending on the existence of a tangible embodiment.
A rather prominent example is the exhaustion principle in copyright. There is reluctance to apply it to intangible copies. Difficulties arise due to the provisions which were adopted at the time when the distribution of intangible copies was not yet a reality. The exhaustion principle is important not only from the perspective of copyright and consumer access to a secondary market of goods, but also from the perspective of free movement of goods at the EU level. The Digital Single Market strategy aims to create a single market facilitating free movement of digital goods within the EU. The exhaustion principle was used early on by the CJEU as an instrument of removing barriers to trade in tangible goods. It is thus important to consider using it as an instrument of creating the Digital Single Market too.
This paper considers the exhaustion doctrine as an instrument of facilitating the Digital Single Market of e-books disseminated through Amazon and a secondary market thereof. The main challenges to the market posed by the exhaustion principle in its current wording are: the concepts of a copy; application of DRM measures; and territoriality of exhaustion. It is apparent that the application of the exhaustion principle to intangible copies will not itself result in a functioning secondary market because of the distinct ways of disseminating intangible goods. Accordingly, technological and organisational challenges to creating a digital single and secondary market must be considered.
Based on the analysis of challenges, two scenarios were identified. The first one implies facilitating a limited secondary market of e-books distributed through Amazon, where subsequent transfers, just as the initial one, are centrally managed. It provides a greater control for the copyright holder and vendor - in this case Amazon. Since 2013 Amazon holds a patent in the US covering such a system. This solution requires implementation of technological and organisational changes on the vendor’s part and maintenance of a centralised system. It would not facilitate transactions involving copies purchased outside the centralised system. Subsequently, such a secondary market would be narrower in scope than a respective secondary market of printed books.
The second scenario - a clearly more advanced and challenging one - is to enable consumers to dispose of a copy of a purchased e-book by extracting it from a trusted Kindle device or Kindle reading application and exporting it with either preserving or discarding the applied DRM policies. There could be different ways to achieve this and researchers in the computer science field have already worked out certain options. For instance, there is a model proposed which allows transfer of intangible copies while preserving the applied DRM policies. This is in line with both the consumer’s and copyright holder’s expectations.
The first identified scenario of a limited secondary market could become a starting point to facilitate a broad secondary market. As it requires less effort on the vendor’s side and allows vendors and copyright holders to retain almost the same level of control as with an initial purchase, it should be largely acceptable. Moreover, this option would allow the preservation of all the DRM policies applied to a copy. As the second step, a system allowing large-scale transfers of digital copies subject to particular conditions, as described in the broad secondary market option, could be developed. Only when such a system is in place, it becomes possible to arrive at a secondary market of e-books similar to the printed books.
In order to overcome the legal challenges, political decisions are required. The absence of a clear and distinctive meaning of certain concepts under EU law makes it difficult to effectively address the identified obstacles to a secondary market of intangible goods. Although the CJEU case law is of crucial importance, the fragmentation of applicable EU copyright legislation leads to differences in the national law. This results in barriers to the free movement of intangible goods.
While implementing the Digital Single Market strategy, the European Commission should consider the exhaustion principle as an instrument to leverage the Digital Single Market and a secondary market for intangible goods as its integral part. The scenarios developed in this paper indicate that different approaches can be taken. It should be possible to achieve a secondary market of e-books in a controlled manner by providing wider access to copyright-protected works while preserving the interests of copyright holders enforcing DRM technologies.

 It is unclear what exactly Amazon’s delivery cost consists of besides the cost of transferring bytes through the network. Some suggest that it includes also the cost of on-demand creation of copies and encryption, i.e. cost of server resources necessary to carry out operations.
 In 2007, the French Court ruled that shipping costs are part of a price for an e-book and fined Amazon for offering e-books at a price lower than 95% of the retail price set by the publisher, which is prohibited by law.

 Broadcasting, performance and other ways of communicating a work without providing a copy for disposal fall outside the scope of this paper.
 To be precise, there is always a tangible medium behind a copy of a work – be it the device where it is stored and from which it can be accessed, a remote server etc. This medium, however, does not have such a distinctive character as a printed copy of a book has. For instance, the physical embodiment of a printed book serves the sole purpose enabling a consumer to enjoy the work, unlike a computer/server/device which is being used in many ways.
 Temporary acts of reproduction transient or incidental, which form an essential part of the technological process enabling digital transmission or lawful use, are exempted from acts falling under the reproduction right of the author according to Art. 5(1) of the InfoSoc Directive.
