Architectural works including buildings, stadiums, bridges, antenna towers, and other artificial constructions become eligible for design patents since the Japanese Design Patent Act Reform came into effect on April 1, 2020. The Japan Patent Office (JPO) recently announced that four design patents for architectural works – a commercial building, a train station building, an interior of book store, and an interior of belt conveyer sushi restaurant – have been registered for the first time ever. See METI’s website.
We are happy to assist you to obtain design patents as well as utility patents. If you have any question regarding the Japanese law and practice, feel free to contact us.
Artificial Intelligence (AI) have been used in a wide variety of areas, including image processing, targeting advertising, natural language processing, robotics, and medical diagnoses. According to the Japan Patent Office’s (JPO’s) annual report, patent applications on AI-related inventions have rapidly increased in number in recent years.
To assist examiners and applicants in understanding how the JPO applies the written description requirement to particular situations, the Office has updated its Examination Handbook to include new Examples 46-51 regarding AI-related inventions.
A machine learning algorithm learns from a training dataset to build a mathematical model. The training dataset includes multiple datasets, typically, example pairs of input and the corresponding output. For example, multiple datasets may include ads data on advertisement activities for a particular product, review data on reviews from customers for the product, and sales amount data for the product. The mathematical model leans to predict sales amount of a similar product in response to receiving ads and review data for the similar product.
Claims may recite a particular mathematical model learned from a training dataset including multiple datasets. Based on the new Examples, the written description requirement is considered to be satisfied in a case where:
the specification includes a statistical analysis or other explanations showing that there are correlations among the multiple datasets to sufficiently build the particular mathematical model (Example 49);
the specification includes a performance evaluation of the particular mathematical model which supports the fact that there are correlations among the multiple datasets to sufficiently build the particular mathematical model (Example 50); OR
even if the specification does not expressly describe about correlations among the multiple datasets, with knowledge of a skilled person at a time of filing, there are apparent correlations among the multiple datasets to sufficiently build the particular mathematical model (Examples 46-48).

The Japan Patent Office (JPO) offers a fee reduction program for examination fees and issue fees for patent applications. A variety of entities can apply to the program.
Thanks to this program, our clients have received great benefit of US$1021.00 per case in average for the past three years. Don’t forget to have your Japanese associates or representatives to file a petition for participating the program if you or your clients meet requirements.
Eligible applicants include:
Small & Medium Enterprises (SMEs);
Corporation tax exempt SMEs;
Small & Medium Venture Enterprises;
Colleges of technology;
Municipal tax exempt individuals;
Income tax exempt individuals;
Enterprise tax exempt individuals; and more.
