It’s been really hot every day, hasn’t it?
For a summer snack, nothing beats a refreshingly chilled water yōkan.
The water yōkan from “Murasakiya,” a renowned Japanese confectionery shop in Nagoya, has a moist texture and just the right sweetness, making it easy to eat even when you’re not hungry.
Before you know it, the whole stick is gone.

I want to get through the hot summer by treating myself to something special.

The trademark “Murasakiya” is registered for “confectionery and bread” under Japanese Trademark Registration number 0527162, dated September 16, 1958.

Kinetic Art

  • July 22, 2025
#Inventions of the Day

I will introduce inventions that are closely related to today (July 22). This time, I will introduce kinetic art, including mobiles.

July 22 is the birthday of Alexander Calder (July 22, 1898 – November 11, 1976), an American sculptor who “invented” mobiles, which are “moving sculptures” known for their use in interior design and educational toys (Montessori mobiles).

Calder’s mobiles are considered to be the starting point of kinetic art.
In connection with mobiles, I would like to introduce the works of Dutch contemporary sculptor Theo Jansen, which have attracted particular attention among the wide variety of kinetic artworks.

If you are wondering, “Contemporary art? What does that have to do with invention?”, please take a look at this video. You will be mesmerized by the Strandbeest, which move smoothly like living creatures when blown by the wind.

Composed of complex and intricate link mechanisms, Strandbeest are works that attract interest from an engineering and physics perspective, but they also seem to offer insights into molecular biology.
They were featured in NHK Special Human Body III: “The Source of Life: The Wonderland Inside Cells” (broadcast on April 28, 2025), so some of you may have seen it. There, it was compared to kinesin, a motor protein involved in material transport within cells. However, the driving force is different. A comparison with viruses, which are considered “non-living,” might also be valid.

Jansen’s Strandbeest are a unique collection of works that blend art and science and technology, and they continue to evolve. They are likely to continue to stimulate the senses of those who see them, awaken forgotten ideas, and provide inspiration. (blink)

Illegal Part-Time Job Prevention System

#patent

Recently, crimes involving illegal part-time jobs have become a serious social issue.

Illegal Part-Time Job

The Metropolitan Police Department has decided to implement a system that automatically detects illegal part-time job postings on social media using AI (reference site: Japanese only). Currently, police officers search social media posts and select those requiring warnings. However, under the new system, AI will automatically detect terms such as “short-term high-paying jobs” and classify risks into several categories.

Illegal Part-Time Job

Japanese Patent Publication No. 2025-52899 (Applicant: SoftBank Group Corp.) discloses an invention for a system to prevent illegal part-time jobs using generative AI. In this invention, a data processing system performs the following processes, for example.

Step 1: The generative AI-based system for preventing illegal part-time jobs initiates chat-based communication with job seekers.
Step 2: A data collection module collects detailed information about illegal part-time work through interactions with job seekers.
Step 3: The collected information is reported to police authorities via a communication module to prevent incidents.

I hope that such technology will contribute to the realization of a safe and secure society free from crime. (Conan)

Mie Support Pokémon

#trademark

In June, I attended the firm’s interaction session at the Toba International Hotel in Mie Prefecture. At Pearl Ocean Terrace, I was soothed by the view of the sea stretching out before me, the pleasant sea breeze, and the sound of the waves.

Among the attractive souvenirs in the hotel shop, I was captivated by the collaboration products featuring the Pokémon “Mijumaru (Oshawott).”
I vaguely knew that certain Pokémon collaborate with specific prefectures, but I didn’t realize that Mijumaru (Oshawott) (Japanese Registered Trademarks: No.5351424, No.5839685) had been appointed as the “Mie Support Pokémon” for Mie Prefecture. This is part of the “Pokémon Local Acts” initiative, where a “favorite Pokémon” is selected for each region to promote its charm both domestically and internationally. Through this initiative, the goal is to encourage more people to visit the region, thereby increasing the number of fans of both the region and Pokémon.

Additionally, the use of Pokémon in this initiative is free of charge, allowing many collaboration products to be sold as souvenirs, which likely contributes to the promotion of local specialty products. The ability to purchase region-exclusive Pokémon merchandise is also a major attraction.

These are souvenirs I purchased as mementos at hotels and shops in Toba City.

The “Isenomon Hand Towel” on the left is made from “Ise Momen,” a traditional craft designated by Mie Prefecture, and is manufactured by Usui Orimono. The company also holds the registered trademark rights (Japanese Trademark No.4971739) for Ise Momen.
I hope that such traditional crafts will continue to be cherished and preserved in the future.

By the way, the Toba International Hotel has a special “Mijumaru (Oshawott) Room” available in only one room! One of the perks is a “hidden Monster Ball search and gift service,” which is sure to get Pokémon fans excited! (Cacao)

Nintendo Switch 2: A Comprehensive Investigation of Intellectual Property Strategy!

  • July 2, 2025
#design #patent #trademark

 I’m Hiro, a fan of home appliances and gadgets.
 The Nintendo Switch 2 has been generating a lot of buzz even before its June 5 release. I casually entered the official store’s lottery for the first batch, and to my surprise, I won the first draw. It arrived on the release date, but with my middle schooler’s midterm exams just two weeks away and a busy schedule afterward, I still haven’t opened it as of June 25 (my child doesn’t even know the Switch 2 is at home yet). I finally have some free time this weekend, so I plan to play with my child.

Nintendo Switch 2

 As is well known, Nintendo places a strong emphasis on protecting its intellectual property. Switch 2 must also utilize a significant amount of intellectual property. I conducted some research based on publicly available information.

 First, when looking into patents, I found a PCT international patent application related to Switch 2.

Patent 1: PCT/JP2023/028162
International Filing Date: August 1, 2023, International Publication Date: February 6, 2025, Invention title: Game controller

Nintendo Switch 2

Patent 2: PCT/JP2023/028163
International Filing Date: August 1, 2023, International Publication Date: February 6, 2025, Invention title: Game Console and Game System

Nintendo Switch 2

 In the previous model (Switch), the controller was attached and detached by sliding it into the display unit, but in Switch 2, this has been changed (improved) to a magnetic attachment/detachment mechanism (reference). Patents 1 and 2 appear to be patents related to this mechanism. The Japanese patent application for Patent 1 was registered on June 2, 2025 (three days before the release date) (Japanese Patent No. 7690703).
 Note that the international publication dates for Patents 1 and 2 (February 6, 2025) are after January 16, 2025, when the official name “Nintendo Switch 2” and a teaser video of the main unit including the controller were first revealed. Since the patent content (drawings) will be internationally published 1 year and 6 months after the filing date (August 1, 2023), it is presumed that the preview video was released before this date.
 In addition to Patents 1 and 2, approximately 25 PCT international applications related to Switch 2 have been filed since August 1, 2023. Among these, there are applications related to the mouse functionality of the new controller featured in Switch 2.
 At present, few of these have been transferred domestically (possibly only Patent 1?), but it is expected that transfer procedures to various countries will be conducted by the respective deadlines for each application. Additionally, there are likely many more Switch 2-related patent applications that have already been filed but have not yet been published.

 Upon further investigation into designs, I found examples of design registrations that appear to be part of the Switch 2 controller (control sticks).

Design 1: Japanese Design Registration No. 1800949
Filing Date: November 12, 2024, Registration Date: June 5, 2025, Publication Date: June 13, 2025, Article to the design: Control Stick Device

Nintendo Switch 2

Design 2: Japanese Design Registration No. 1800950
Filing Date: November 12, 2024, Registration Date: June 5, 2025, Publication Date: June 13, 2025, Article to the design: Control Stick Device

Nintendo Switch 2

 The registration date coincidentally matches the release date of Switch 2 on June 5, 2025, with the publication date set for June 13, 2025. If the publication date had been before the release date, the shape of the back side of the control stick—which cannot be seen without disassembling the controller—would have been disclosed prior to release. This makes the registration date and publication date exceptionally well-timed. By the way, if you do not want to disclose the design during the registration examination, you can delay the publication date through the confidential design system.
 By registering the control stick as a component, I believe this will prevent counterfeit (substandard) control sticks from being produced as replacement parts by other companies. At present, there seem to be only the two examples of design registrations related to Switch 2, but I expect many more examples will be disclosed in the future.

 Additionally, when researching trademarks, I found an example of a trademark registration for the Switch 2 logo mark.

Trademark 1: Japanese Trademark Registration No. 6917075
Filing Date: January 16, 2025, Publication Date: January 24, 2025, Registration Date: April 9, 2025

Nintendo Switch 2

Trademark 2: Japanese Trademark Registration No. 6917076
Filing Date: January 16, 2025, Publication Date: January 24, 2025, Registration Date: April 9, 2025

Nintendo Switch 2

 The above trademarks were filed on the same day as the first public release of the teaser video for “Nintendo Switch 2” (including the Switch 2 logo mark) on January 16, 2025.
 This prevents the logo mark from becoming publicly known before Switch 2 is released and also prevents others from filing prior applications.
 Additionally, according to the Global Brand Database, trademarks similar to the above two trademarks have been filed in various countries around the world.

 Nintendo is securing comprehensive protection for a single product (Switch 2) by obtaining multiple intellectual property rights (patent rights, design rights, trademark rights).
 In the case of patents, applications are published 1 year and 6 months after filing; in the case of designs, they are published after registration following an examination; and in the case of trademarks, applications are published approximately one week after filing. Nintendo likely considered these publication timelines carefully when determining the announcement date, release date, and other details for the new product (Switch 2).

 For companies developing new products, intellectual property strategy is of utmost importance.
How should patents, designs, and trademarks be combined for protection? How should the timing of disclosure, announcement, and release be determined? Drawing on real-world examples, we can propose the optimal strategy for your needs. Please feel free to contact us at our firm for further discussion.
