Blockchain and its application in the field of IP

Smart Contracts and IPR management

05 November 2021

While the bandwidth of use cases is still subject to ongoing research, one of the fields that will profit from the possibilities of blockchain are "smart contracts", i.e. legal contracts built and executed (entirely or in parts) by means of software. This article provides a glimpse at what role intellectual property rights might take in this "new world" of blockchain and smart contracts.

The enormous potential of blockchain and its real-world application has increasingly gained traction throughout all industries. In 2017 the dreamlike growth in value of the blockchain-based cryptocurrency "Bitcoin"[1] brought the concept of blockchain to the attention of the general public. However, the ongoing debate about Bitcoin's suitability as a financial investment and the ecological impact of Bitcoin mining should not detract from the fact that the underlying technology of the blockchain-protocol and similar technologies based on the idea of a decentralized register are going to have tremendous impact on how we – and machines[2] – do business in the future. This is especially due to the fast-growing digitization and automation of our world in general. While the bandwidth of real-world use cases is still subject to ongoing research, one of the fields that will profit from the possibilities of blockchain are "smart contracts", i.e. legal contracts built and executed (entirely or in parts) by means of software. The present article aims to provide a first glimpse on how Intellectual Property Rights ("IPR") might play a role in this "new world" of blockchain and smart contracts.[3]

Blockchain and Smart Contracts – an overview

The blockchain-protocol was first introduced in a whitepaper published under the pseudonym Satoshi Nakamoto in November 2008.[4] The whitepaper describes a concept where bundles of transactions (blocks) between users (nodes) are cryptographically linked in chronological order, creating a continuous, tamper-proof register (chain) that is stored and managed by all users simultaneously (distributed ledger). Intermediaries such as centralized service providers are not required. Each user disposes of a private key (to initiate a transaction) as well as a public key (to receive funds). Dedicated participants of the network (miner) provide the necessary computing power to validate transactions (Proof-of-Work) while creating (mining) Bitcoin as reward for their expenses (e.g., hardware, energy costs). However, Bitcoin is only one application of distributed ledger technology, which is expected to be useful in a broad variety of other cases across almost all industries in the future.[5]

Smart contracts, a concept first postulated by the computer scientist Nick Szabo in 1994[6], are intended to execute contractual obligations through software code. For example, if a certain pre-defined condition is met (e.g., confirmation of a payment), the code triggers the respective legal consequence(s) (e.g., dispatch of delivery good; grant of access to know-how). In this context, a blockchain linked to a smart contract could provide the parties with a transparent, verifiable, tamper-proof register to record the contract's execution. But not all types of contractual obligations can be described by a (rather simple) digital true/false- or if/then-scheme which is more applicable to standardized procedures.[7] More complex tasks on the other hand, such as:

  • the compilation/execution of contractual obligations;
  • the weighting of the parties' interests; and
  • the construction of undefined legal concepts like "reasonable" or "necessary",

may not be mastered by software alone, but will likely require human intellect in order to resolve any disputes in a fair and well-balanced way – at least with current technical means.

Blockchain-based IP register

Any type of IP (e.g., patents, utility models, trade marks, know-how etc.) could be subject to a blockchain-application as the object of the transactions can be freely defined dependent on the purpose of the respective use case. One field of application may be (public) IP registers such as the German or European patent and trade mark registers. For example, assignments of IP rights, licenses or pledges on patents could be entered into a blockchain-based IP register directly by the parties (respective software API provided), reducing time and costs of Office proceedings. In addition, it could render the register more reliable regarding the substantive legal situation, ensuring the register is kept more up-to-date.[8]

In the context of any development agreement, any work results (e.g., contributions of collaboration partners, freelancers) - or rather the IP's corresponding "digital fingerprint" (hash value) can be stored in the blockchain, enabling the contracting parties (as well as any other third parties) to verify the IPR's coming into existence at a certain point in time (Proof-of-Existence). Such proof can be of particular importance if the applicable legal regime does not provide for a registration mechanism (conveying absolute rights to a person on a given subject matter) such as (German) Copyright law.

Consequently, in 2019, the World Intellectual Property Organisation held a first conference on use cases for blockchain technology in the field of intellectual property data sets.[9] One major goal of WIPO's "Blockchain Task Force" is to "explore the possibility of using blockchain technology in the processes of providing IP rights protection, processing information about IP objects and their use".[10] In that context, WIPO's "Blockchain Whitepaper Project" aims at preparing a whitepaper to further research opportunities and challenges, identify potential use cases and develop recommendations on interoperability and governance with respect to the IP ecosystem.[11]

Going one step further, as part of the EU Commission's recent "Action Plan IP"[12], the EU intellectual property office ("EUIPO") is actively researching ways to put blockchain into use and has recently launched the world's first official blockchain-based trademark and design register in April 2021. The new blockchain (with its first "genesis block" been created at 08.10 CET on 17 April 2021) automatically stores data related to registered IP rights across various IP offices. EUIPO's online platforms TMView and DesignView (gathering more than 62 million trade marks and 17 million designs) are now fully connected to the blockchain and updated in real time.[13] Malta is the first country having joined the blockchain network on 1 July 2021[14] with many offices across Europe expected to join over the next months. Other use cases currently explored pertain to the adiministration of copyrights and the EU's anti-counterfitting infrastructure.

Micro-licensing and Smart R&D Agreements

With respect to smart contracts, blockchain may further be suitable for the management of access authorization and the grant of licenses. For example, access to digital online content[15] (e.g., music, videos, photos, other documents) would only be provided if the respective payment made by the user was validated in the blockchain. Similarly, in case of licensing relationships, the smart contract/blockchain could track the grant of licenses and/or sublicenses and the orderly payment of royalties (which could be calculated based on the number of acquired licenses or other data).

Another use case may be "Smart" Research and Development ("R&D") Agreements where the collaborating parties license their existing IP to each other in order to create new IPR. The regime of allocating ownership of (new) IPR and (unilateral/mutual) licensing of project IPR might be handled via a blockchain solution. Moreover, confirmation that certain project milestones are reached (e.g., successful development of a first-stage prototype) could unlock further funds.

However, so far blockchains have their limits where more complex issues such as legal assessments become necessary. That could include the evaluation of whether the developed subject matter actually complies with the desired research results envisaged under such "Smart" R&D Agreement or any construction of a term which needs interpretation.


Industry 4.0 and the technologies that come with it are still in their early stages. However, it is clear that digitization and automation of entire industries are progressing at a fast pace and will shape our lives over the next few decades. With respect to blockchain and the design, supervision and enforcement of smart contracts, it is clear that IP lawyers will need to accumulate the necessary IT know-how to render effective legal advice. While it might not yet be entirely clear to what extent these new technologies will be implemented or when the necessary software standards will be available, first use cases appear to be promising and should be closely monitored from the start [16]

Key take-away points
  • In general, first use cases of blockchain and smart contracts appear to be promising, but further research will be required to assess the full potential and possible legal challenges in the future.
  • Copyright and patent law provide the required legal means to protect any new development in this field.
  • IP could be subject to and managed by smart contracts. However, certain limits are reached where human judgment is required (e.g., construction of legal concepts such as "reasonable" or "necessary).

[6] According to Szabo, a smart contract is "a computerized transaction protocol that execute[s] the terms of a contract".

[7] For this reason, smart contracts are often compared to vending machines where inserting a coin and selecting the desired leads to the releasing of the good to the client.

[8] For example, the German patent and trade mark register is many cases outdated as the parties may transfer the respective IPR without informing the Office as the change of the respective register entry is no requirement for the transfer to become legally effective. Especially in case of large portfolios, the parties tend to refrain from filing such update for time/cost reasons.
