In a rapidly evolving technology world, blockchain stands out as a revolutionary force, reshaping many industries with its decentralized, secure and transparent nature. From cryptocurrencies to smart contracts, from decentralized autonomous organizations (DAOs) to non-homogeneous tokens (NFTS), the applications of blockchain technology are broad and diverse. However, as with any breakthrough innovation, how to protect these inventions through patents has become a topic of concern for developers and companies alike.

The nature of blockchain technology

The core of blockchain technology is to provide a decentralized ledger system that enables secure and transparent transactions without the need for intermediaries. This basic concept has spawned various applications, including Ethereum's smart contract platform and Bitcoin's cryptocurrency framework. The versatility of blockchain extends beyond financial transactions, promising major changes in areas such as supply chain management, healthcare, and intellectual property management.

The role of patents in blockchain innovation

With the gradual popularization of blockchain technology, more and more people have begun to pay attention to how to provide patent protection for innovations involving blockchain. Patents play a key role in protecting novel ideas and thus ensuring that inventors can benefit from their inventions without fear of unauthorized use or reproduction by others. In the blockchain space, patent protection can cover a wide range of innovations, from the underlying algorithms and data structures all the way to specific applications such as smart contracts and cryptocurrency mechanisms.

Possible challenges and considerations when seeking patent protection for blockchain

Given the fundamental nature of blockchain technology and its wide applicability in different fields, people may encounter unique challenges when filing patents for blockchain technology. The Patent Act of the United States states that the subject matter eligible for patent protection includes any new and useful method, machine, product or substance composition, or any new and useful improvement, which does not include laws of nature, natural phenomena and abstract concepts. To assess eligibility for a patent, the parties used the "two-step framework" in the United States Supreme Court's Mayo v. Alice case. In the first step, one should determine whether the claims relate to concepts that do not qualify for a patent, such as abstract concepts. The second step will then be to assess whether certain elements of the claim can be converted into an application that, while containing an ineligible concept, is eligible for patent protection.

For example, in PersonalWeb Techs. LLC v. Google LLC and YouTube LLC, the Federal Circuit held that, under 35 U.S.C. § 101, Claims relating to "data processing systems that assign unique identifiers to data based on content" are not eligible for a patent. In this case, PersonalWeb Techs.LLC alleges that Google LLC and the other defendants infringed three U.S. patents (No. 7,802,310, 6,415,280, and 7,949,662) relating to technology for generating content-based identifiers using algorithms such as cryptographic hacks. The court eventually declared the patents invalid and found them ineligible for a patent.

Similar to the situation in the PersonalWeb case, obtaining a patent involving blockchain technology is like obtaining a patent for an algorithm, which is clearly a concept that does not qualify for patent protection and does not pass the first step of the "Alice test." The key here, therefore, is to determine whether the inventions that claim protection also document other elements. If these elements can turn a claim into an application that actually qualifies for protection even though it contains an ineligible concept, they will survive the second step of the Alice test.

In order to properly address the complexity of patentability (especially step 2 of the Alice Test framework), one must demonstrate how the invention claiming protection uses certain elements to transform a portion of a potentially non-patentable concept into a viable application. For example, when seeking patent protection for blockchain technology, one must highlight in the claim how blockchain can further enhance computer functionality. In view of the growing importance of Section 101's analytical description requirements, applicants are required to detail improvements in computer functionality, such as increased processing speed, reduced network data transmission and reduced power consumption. The above description should make it clear that the relevant invention concepts solve unique challenges in computer technology and provide similarly technology-based solutions.

The future of blockchain patents

As companies and inventors continue to strive to establish their dominance in this field of innovation, the competition among blockchain patents is becoming increasingly fierce. While the number of new patent applications seems to have decreased, the continued interest shown in blockchain over the past few years highlights the critical role it will play in driving the next wave of digital innovation across multiple fields.

With its rapidly growing influence, blockchain technology has the potential to transform industries from finance to logistics, and make patent acquisition a fundamental strategy that entities will adopt as they protect their breakthrough innovations and foster continued innovation. A variety of top competitors, including tech giants, banks and emerging players, have shown great enthusiasm for investing in the capabilities provided by blockchain.

As blockchain patents continue to accumulate, it is expected that the interaction between technological progress and intellectual property protection will significantly affect the future development of blockchain. This could have a profound impact on the way blockchain is integrated into various fields and could change related business models and industry norms.
