Citrus jabara (CJ) is a rare citrus fruit that used to grow naturally only in the southern part of the Kii Peninsula in Japan. Human intervention studies with oral intake of CJ fruit have shown its anti-allergic effects, but the testing method was a pre-post comparison study. In this study, we conducted a randomized, double-blind, parallel-group interventional study to evaluate the volume-dependent effects of oral intake of CJ fruit peel powder (Japanese Patent No. 5,323,127) on nasal and eye allergy-like symptoms. Ninety healthy adults were allocated to three groups and given test foods containing 1,000, 500, and 0 mg of CJ peel powder, with one packet per day for 4 weeks. After excluding those who dropped out or deviated from the study protocol, 73 were included in the efficacy analysis and 86 in the safety analysis. The high-dose group (1,000 mg/day) was significantly lower than the placebo group in the scores of “nasal and eye symptoms” at week 4, and “blocked nose” at weeks 2 and 4 in the evaluation of question I of Japanese Rhino-conjunctivitis Quality of Life Questionnaire (JRQLQ No. 1). The changes in scores (difference from the pre-observation period) on the Nasal and Eye Symptom Questionnaire showed a dose-dependent reduction in rhinorrhea. In the safety evaluation, there were no significant differences in examinations of physiology, hematology, and blood biochemistry between the groups, and no adverse events attributable to the test foods were observed. These results suggest that intake of CJ peel powder can alleviate allergy-like symptoms.

Abstract This article develops a comparative analysis of specialised courts in intellectual property across both Japan and the US. This article considers the IPHC through the lens of the CAFC to investigate the differing institutional impact and illuminate the most pressing issues in Japanese patent law that have emerged as a result of transplanting this specialised court. Rather than a more conventional analysis of the implementation of these institutions, this article focuses instead on a comparative investigation of the soft law elements that have significantly influenced their effectiveness, providing a different insight on the relationship between these institutions and their broader contextual impact. The main findings of the comparative analysis are found in two primary areas – the impact of specialised courts on the consistency and reliability of patent law; and secondly, recommendations regarding the potential reform of Japanese patent law as it relates to the role of the IPHC. In terms of reform, this article analyzes the double-track problem in Japanese patent law and the key role that, with some modification to the court/patent office relationship, the IPHC could play in addressing this issue with a more fundamental realignment of patent law with its Continental history.

This article is a modest attempt to shed some light on the question of linkages between backward and forward citations in technical fields posed by Trajtenberg et al. (1997). They found interesting similarities and high correlations between equivalent measures looking forward and backward. They also implied the linkage between distant backward and distant forward citations. There are several questions to be posed in applying their insights to Japanese patent applications, however, due to the differences in the patent classification system and the subject of citation, i.e., citations by the applicant or examiner, between the US and Japan. In addition, and most importantly, the possibility that subsequent classifications may match, even if the first classification is different, is unavoidable with existing measurement methods of technical distance. In order to investigate these research questions, the author proposes a new measurement method for the technological proximity between examiner’s citations and their originating patents using IPC-based patent classifications. Using such a proposed method, the author created two hypotheses and tested them for about 14,000 examined patent applications filed in 2008 with the JPO. As a result of testing Hypothesis I, the author confirmed that Trajtenberg et al.’s insights can be applied to Japanese patent applications using citations by the examiners and IPC-based patent classifications. In other words, it was confirmed that patent applications citing backward citations categorized in a technical field distant from the invention are more likely to be cited by forward citations categorized in a technical field distant from the invention. As a result of the verification of Hypothesis Ⅱ, it was further confirmed in some technical fields that the backward citations categorized in a technical field distant from the invention are more likely to be in the same technical field as the forward citations categorized in a technical field distant from the invention. The author believes that these verified results indicate the possibilities of using backward citations as a starting point from which we can find patent applications for inventions at an early stage with potential applicability to other technical fields.

SDGs is an abbreviation for “Sustainable Development Goals”, which were adopted at the United Nations Sustainable Development Summit in September 2015. They were set as goals to be achieved by the 193 United Nations Member States during the 15-year period from 2016 to 2030. Technological innovation is indispensable for the realization of the SDGs, but at present, it is unclear where (countries and companies) and to what extent SDG-related technologies are available. For this reason, we used BERT, a natural language processing technology, and Japanese patent publications we own and worked on the "visualization" of the SDGs technologies in Japan. The results show that out of the 17 SDGs goals, patents can contribute to Goals 2, 3, 6, 7, 9 and 11.

In development of technology and product, it’s important to make decisions based on technology trend. Some previous studies obtained technology trend based on patent information. In our previous study, we tried to investigate the state of innovation and the emergence of dominant design by using patent information. We analyzed inkjet printers and NC machines with theme codes and F term codes in Japanese patent classification codes. In this study, we tried to know the change of technology of other products other than inkjet printers or NC machines by using patent information. The target product of this study is camera. Camera products changed its key technology of imaging and recording from analogue film to digital imaging sensor and semiconductor memories. We attempted to obtain this change by using patent information.

Although it may not be clear whether AI may generate the invention autonomously without human intervention, recent development of AI produces inventions of AI technologies such as machine learning (deep learning). Inventors also have begun to use AI as a tool to help them create inventions. These AI-assisted inventions raise the urgent and practical issues of patentability such as patentable subject matter (patent eligibility), disclosure requirements, and inventive step (non-obviousness). The Japanese Patent Office (JPO) updated the Examination Handbook to address some of the issues. For instance, they discussed to what extent inventors should disclose in patent applications because AI as a black box does not explain how the problems are solved. However, the JPO did not pay much attention to the possibilities that not only inventors but also a person having ordinary skills in the art (PHOSITA) might use AI and PHOSITA with the aid of AI could create the inventions more easily, thereby raising the level of inventive step. This chapter critically reviews the JPO’s updated Handbook and discusses whether and how we can take into account the use of AI by PHOSITA in examining inventive step.

Despite advocating openness, technology leaders have been patenting artificial intelligence (AI) inventions at an exponentially increasing rate. Patents on foundational techniques with broad applications have the potential to deter innovation in the field, should the privatization of key components of artificial intelligence be used to exclude third-party innovators. This chapter studies patent applications in the US and demonstrates the extent to which the field has grown over the last twenty years. It then seeks to explore foundational patents by focusing on triadic patents: patents filed jointly with the United States Patent and Trademark Office, the European Patent Office, and the Japanese Patent Office. The results of this chapter indicate an increasingly globalized AI field. A proverbial land grab seems to be occurring; an increase in AI patenting, particularly the protection of triadic patents, illustrates industry players aggressively attempting to own the building blocks of a rapidly emerging market. A number of policy levers are presented, highlighting how the patent offices and courts can counter the patenting of foundational patents by relying on strict and narrow patentability standards.

Abstract A low-quality patent system threatens to slow the pace of technological progress. Concerns about low patent quality are supported by estimates from litigation studies suggesting that most US patents granted should not have been issued. We propose a new model for measuring patent quality, based on equivalent patent applications submitted to multiple offices. Our method allows us to distinguish whether low-quality patents are issued because an office implements a low standard or because it violates its own standard. The results suggest that quality in patent systems is higher than previously thought. Specifically, the percentage of granted patents that are below each office’s own standard is under 10% for all offices. The Japanese patent office has a higher percentage of granted patents below its own standard than those from Europe, the USA, Korea, and China. This result arises from the fact that Japan has a higher standard than other offices. (JEL O34, K2, L4, F42)
