  • Examining the Legitimacy of Patent Enforcement on Recycled Commodities: Comment on the Japanese Decision Ricoh Case Invited

    Yusuke TACHIBANA

    PATENT STUDIES   ( 77 )   52 - 79   2024.3

     More details

    This paper is a precedent commentary on the so-called “Ricoh Toner Cartridge Case.” At the initial hearing it was decided that restrictions on recycling are considered trade interference under the Antimonopoly Act, and this also received attention from the appeals court since this meant that the exercise of patent rights constituted the inappropriate use of rights.
    The defendant had produced and sold recycled toner cartridges originally manufactured by the plaintiff. During the recycling process, the defendants replaced the IC chip with a new one. This was because the plaintiff’s IC chip which detects the amount of toner that is remaining could not be reset and reused. The plaintiff alleged patent infringement with respect to the replacement of the IC chip. In response to the initial hearing, the appellate court denied that this was a violation of the Antimonopoly Act and did not recognize this as an inappropriate use of rights.
    Why did the judgements of the initial hearing and the appellate court differ? The reason for this would appear to be in the criteria for determining the inappropriate use of rights and the application of facts to the law. When there is a suspected violation of the Antimonopoly Act in the exercise of intellectual property rights, this has typically been considered an issue under Article 21 of the Antimonopoly Act. It is commonly believed that the Antimonopoly Act applies when there is a deviation from the purposes of the intellectual property system, and in such cases consideration is given to the extent to which competition is restricted in the market. Behind this is the understanding that both the Intellectual Property Act and Antimonopoly Act have the common objective of promoting competition with respect to intellectual property. There is also the view that there is no need to note the common purpose of both laws. However, when this view is extended, the issue is whether the enforcement of the rights provided by the intellectual property system exceeds mere protection. It is only when the protection at issue has a common purpose with the Antimonopoly Act that the violation of the Antimonopoly Act can be decisive in determining the inappropriate use of rights. On this point, the appellate court took the former position, while the court in the initial hearing was sympathetic to the latter position.
    From the perspective of the appellate court, the violation of the Antimonopoly Act was considered decisive. Looking at the facts of this case in which the question concerned the restriction of competition with respect to consumables, the deciding factor may have been the need for the products to be genuine. In this regard, the findings of the initial hearing and the appellate court differed as to whether patent infringement can be avoided when recycling, and the differences in recognition can be said to be one reason for this variance between the two courts.

  • Law and Policy on the Cyber Supply Chain Security in the United States: 117th United States Congress 2nd Session

    Yusuke TACHIBANA

    Research bulletin of Fukuoka Institute of Technology   56 ( 2 )   45 - 58   2024.2

     More details

    In the second session of the 117th Congress (2022-2023), there were significant changes in supply chain security. The supply chain security community made progress in revising NIST SP 800-171, a fundamental document for contractors in the field of supply chain security. They also focused on various themes, including the Software Bill of Materials (SBOM), zero-trust, and the notification scheme in the Cyber Incident Reporting for Critical Infrastructure Act (CIRCIA). These initiatives were responses to major security incidents, such as the Colonial Pipeline breach and the Log4j vulnerability incident. Additionally, security enhancements against China, such as the CHIPS Act, along with restrictions on TikTok, saw advancements. However, there were significant policy failures in the area of Systemically Important Critical Infrastructure (SICI).

  • Spare Parts and Design Rights in the EU through the Acacia Case – A Revisiting from Right to Repair Theory –

    Yusuke TACHIBANA

    Research bulletin of Fukuoka Institute of Technology   55 ( 2 )   79 - 96   2023.2

     More details

    The "right to repair" is defined as the user's right to decide on the product, but current legislation takes forms of obligations to provide repair parts and repair manuals from authorized product manufacturers to the users or the independent repair service providers. In other words, the current “right to repair” legislation does not address the prevention of the repair by the manufacturer’s intellectual property rights. Then, what measures can be taken to tackle that situation? In this respect, in EU design law, the "repair clause" which legalizes repair using spare parts has existed since before the "right to repair" was discussed. This paper follows the discussion of the repair clause through the leading case, the Acacia case, and explores whether the clause contributes to the "right to repair" and the pros and cons of such clauses. As a conclusion, the repair clause of EU can support the "right to repair". On the other hand, the extensibility of the clause may differ depending on whether the rational of the exception provision is considered as the competition law and the exhaustion doctrine or, beyond the traditional those theories, given the meaning of an "environment-oriented" right to repair to promote the circular economy.

  • Law and Policy on the Cyber Supply Chain Security in the United States -117th United States Congress 1st Session-

    橘雄介

    福岡工業大学総合研究機構研究所所報   ( 5 )   63 - 74   2022.10

     More details

    The first session of the 117th Congress (2021-2022) was a year of significant change for supply chain security in two ways. The supply chain security community made progress on the revision of NIST SP 800-161, the basic document in the area of supply chain security, and on the rapid development of key policies in response to major security incidents, such as the Colonial Pipeline incident and the Log4j vulnerability incident.
    On the other hand, there have been the following room to do. The Cybersecurity Maturity Model Certification (CMMC), a framework for mandatory information security measures for contractors in the Department of Defense, was temporarily suspended. And a bill that would establish a new information sharing framework between the public and private sectors regarding security incidents did not reach an agreement. Those may indicate the difficulty of making information security management mandatory, which was originally based on the voluntary approach.

  • Regulatory Developments in the UK Broadband Market: Focusing on Competition/Investment, Organizational Structure and Co-Regulation Reviewed

    The purpose of this study is to summarize the developments of the UK telecommunications law, particularly the regulations for BT as an infrastructure incumbent, and to highlight its characteristics.
    In the U.K., Openreach, a wholly owned subsidiary of BT, is engaging telecom infrastructure business. Broadband operators in the U.K. still need to use Openreach's facilities in many geographic areas. Therefore, it is necessary to prevent abuse of a dominant position and preferential treatment of BT by Openreach. The former is an issue of "SMP (Significant Market Power) regulations" and the latter is an issue of "equality of access and operational separation."
    Although there have been prior studies on the UK's telecoms law, there are two reasons why we have undertaken this study.
    The first reason is to contribute to Japan's telecoms policy by updating the previous studies of UK's initiatives. As a background, the construction of high-capacity communication networks has become a global issue in the context of the demand for digitalization.
    The second reason is to summarize the characteristics of the regulation for the British incumbent, with regards to the following factors: Japan's regulation for NTT is in its period of change; and ex-ante regulations for platforms based on the size of companies are being considered worldwide.
    With the above in mind, this study focuses on the UK telecoms law since the 1980s. As a result, the following points can be highlighted: regulations for the incumbent operator has shifted its focus from service competition (promoting market entry and hence price competition) to infrastructure competition (encouraging investment by competitors); operational separation is exercised in the UK as "co-regulation" with a focus on organization; and the guiding principles of "competition/investment" and "organization (co-regulation)" can have a more general value, not limited to telecoms market.

    本報告はリコー・トナーカートリッジ事件の控訴審判決(知財高判令和4.3.29令和2年(ネ)10057号〔情報記録装置〕)の判例評釈である。この事件はリサイクル品に対する特許権に基づく請求が権利の濫用(民法1条3項)を構成するかが問題となり、後述の通り第一審は請求を棄却したが、控訴審は請求を認めた。では、いずれを是とすべきだろうか。この点、循環経済の観点から新たな分析はできないのだろうか。すなわち、既存の法理を超えたメタ的な価値から問題を捉えることはできないだろうか。本報告はこの観点から控訴審判決を批判的に検討する。

  • A Study of the Japanese Version of the Security Clearance System, or Suitability Assessment System: From a Supply Chain Security Perspective

    Yusuke TACHIBANA

    IEICE Technical Report SITE2024-42   243 - 246   2024.7

     More details

    This paper examines the so-called "Japanese version of the security clearance (suitability assessment) system". This system was enacted in May 2024 as the "Act on the Protection and Utilization of Critical Economic and Security Information". This law designates information that may affect security as "important economic and security information" and restricts the handling of such information to those who have no risk of leakage. The reason it is called "security clearance" is because the latter certification is based on a proper evaluation of employees. This system is a milestone because it expands the scope of the Protection of Specified Secrets Act to civilian officials and civilians, and includes a proper evaluation system that was not included in the Economic Security Promotion Act. It is also said that this system will make it easier for Japanese companies to participate in government procurement in Europe and the U.S. In this sense, the system also has a supply chain security aspect. However, there are issues to be addressed regarding the appropriateness of the operation of the system, such as how to minimize the designation of economic and security information subject to the system in relation to the public's right to know, and how to ensure the privacy rights of those subject to due diligence. This paper summarizes the contents and issues based on the discussions on this system.

    The European Commission has indeed proposed a draft Ecodesign for Sustainable Products Regulation (ESPR) that will establish environmental requirements for products placed on the EU market. The Ecodesign Directive has already included repair requirements, such as the obligation to provide repair parts for a certain period of time after the product is placed on the market, but the products covered and the nature of the obligation were limited. The proposed regulation goes beyond this and includes a framework for providing repair information to independent repair service providers (product passport) and promotes the "right to repair."

    The replication of third-party software in the realm of information security research has the potential to encroach upon the copyright of the said software. In this context, the Circuit Court of Appeals in the United States has determined that the replication of an operating system for the purpose of security research qualifies as fair use and does not constitute a violation of copyright. This case has garnered significant attention from researchers in the field of cybersecurity, with the Electronic Frontier Foundation and Public Knowledge submitting an amicus curiae. This report aims to analyze the aforementioned judicial ruling.

    In March 2023, the European Commission adopted a draft Directive on Common Rules to Promoting the Repair of Goods. The draft directive aims to make repairs more affordable for consumers and to reduce waste. The background is the so-called "right to repair" argument. This paper analyzes this draft directive and contributes to the "right to repair" legal policy.

    In December 2022, the Digital Fair Repair Act was passed in New York State, USA. This act is attracting attention as a "Right to Repair" law that requires manufacturers of digital devices to provide the same diagnostic and repair information to other independent repair businesses and consumers if they provide such information to certain repair businesses. However, the law also suffered a setback when it was signed by the governor, limiting the products covered by the law to those sold on the retail market. This report examines this law and analyzes its contents and underlying policies in order to contribute to future discussions of the Right to Repair.

    Patent misuse is an unequitable extension of patent rights. When misuse is found, remedies for the patentee are denied. The interest of this paper is to obtain legal policy implications on the extension of patent rights. For example, in the U.S., how to make indirect infringement of patent rights more flexible is a legal policy issue, but on the other hand, expansion of the scope of patent rights may restrict competition. Therefore, the distribution of roles between patent law and antitrust law is also an issue in the extension of patent rights. These issues are common to Japan. This paper examines the development of misuse through the Kimble case, a Supreme Court decision on misuse by the U.S. Supreme Court, and points out that its characteristics are a departure from property rights doctrine, separation from antitrust law, and categorical protection of the public domain.

    法律はSDGsと関係があるでしょうか。これは「大いにYES」です。たとえば、SDGs 目標9「産業と技術革新の基盤をつくろう」を達成するために、特許法や著作権法などの知的財産法が貢献しています。他方で、こういった法律がSDGsを阻害することもあります。SDGs目標12「つくる責任、つかう責任」ではリサイクルが促進されていますが、スマートフォンや自動車を修理することは知的財産権を侵害し、許されないことがあります。これに対しては、「修理する権利(right to repair)」という運動が欧米で起こり、企業が対応を迫られています。今回の講義では、「知的財産権とは何か?」、「修理する権利とは何か?」ということを学びたいと思います。
