Ballpoint Pen Drawings

  • September 29, 2025
#Inventions of the Day #patent

Today (September 29th), I will introduce an invention closely related to this date.
This time, I will feature the ballpoint pen.

September 29th marks the birthday of Hungarian-born inventor László Bíró (1899.9.29-1985.10.24), who obtained the first practical ballpoint pen patent.
 That said, the technology behind ballpoint pens and the story of László Bíró are already widely known (1, 2). Therefore, this time I will introduce ballpoint pens as an art medium (ballpoint pen drawings), which is quite different from their image as writing instruments.

We rely on ballpoint pens daily, both at work and home. But haven’t you ever gotten annoyed when the ink clogs and your writing gets messy? I certainly have (laugh). For someone like me, it’s hard to believe those beautiful drawings above could be created with that same ballpoint pen.
Even if such artistic use seems impossible, using a Spirograph gear-based drawing tool? seems like it could let amateurs create pretty patterns.

Incidentally, the Spirograph we know today is an educational toy developed by English inventor Denys Fisher (3, 4(PDF)). It became a craze in Japan in the late 1960s (Showa Era year 40s). Nowadays, similar products are sold under names like “Spinning Ruler” or “Design Ruler”.

Celebrating a 60th Birthday with a Touch of Wit

  • September 17, 2025
#trademark

While searching online for a small gift to celebrate a relative’s 60th birthday, I stumbled upon something uniquely funny.

When it comes to Kanreki (60th birthday) celebrations, there’s a custom of wearing a “red chanchanco (Japanese padded vest)”. Red is considered a color that wards off evil spirits and brings good fortune, so I thought “something red to wear” would be perfect. An invisible red belly warmer seemed like something they could easily use.
That’s when I found this belly warmer – the one that made me think, “This is it!”

This belly warmer is an original, customizable product designed, produced, and sold by Shalemon Co., Ltd., located in Yatomi City, Aichi Prefecture.
You can have names or other text printed in the blurred area.
Additionally, it comes with a celebratory “noshi (gift wrapping) paper” attached to the back, making it ready to hand over as a gift.

The phrase “kanreki damono” printed on the belly warmer is a registered trademark of Shalemon Co., Ltd.
The company logo in the lower left corner, though color-inverted, is also a registered trademark.
They hold 17 other registered trademarks and have 5 trademarks pending, firmly protecting their original brand while offering a wide range of uniquely humorous underwear.
If you’re interested, why not take a look at their official online shop?

When we gathered for the Obon dinner, I was able to hand it over safely, and both the recipient and everyone else broke into smiles.
By the way, the gathering was held at “Unagi Kappo Mikawa Sansuitei” in the Mikawa Isshiki area of Aichi Prefecture. It’s a restaurant where you can enjoy delicious eel at a great value, and it’s one of the three shops collectively known as the “Mikawa Isshiki ‘Eel Big Three’”. The logo mark “Mikawa Isshiki/Eel Big Three” is also properly protected as a registered trademark and was part of their brand strategy!♪ (Cacao)

Career Yearbook 2025: Introducing Jobs for Elementary and Junior High School Students

  • September 10, 2025
#intellectual property #patent #patent attorney

 The Asahi Student Newspaper recently published “Career Yearbook 2025”.
Asahi Student Newspaper Career Yearbook 2025”(Japanese only)

Career Yearbook 2025

 The “Career Yearbook” is a career education resource for elementary and junior high school students, first published in 2016 as part of the career education support project “Career Museum.” Each year, with the cooperation of leading Japanese companies and organizations, it introduces various jobs and people who support society.
 It is structured so children can enjoy learning about the world’s jobs through a format where companies and organizations answer their simple questions, such as: “What are gummy candies made of?”, “Why can heavy rockets fly into space?”, “Is it true animals might disappear from Earth?”, and “What kind of pen is a highlighter?”.

・The work of patent attorneys is also featured
 “Career Yearbook 2025” covers the work of over 110 companies and organizations, including the role of patent attorneys.

 The article, timed with the ongoing EXPO 2025 Osaka-Kansai World Expo, highlights the “Progress of the Telephone” over 55 years since the 1970 Osaka Expo. It uses a two-page spread to explain the role of intellectual property rights like patents and the contributions of patent attorneys throughout this evolution.
 A web version with a “Review Quiz” is also available. “From Black Telephones to Smartphones: Why Did the Telephone Evolve So Much?”(Japan Patent Attorneys Association) (Japanese only)

・Free distribution to schools, e-book version also available
 “Career Yearbook 2025” is distributed free of charge to approximately 30,000 elementary and junior high schools nationwide. It is also possible to purchase the commercial version or view the e-book version.

 I would be delighted if children reading this book find it a catalyst for considering their future paths and develop an interest in the work of patent attorneys. (Hiro)

Long-Life Bread

  • September 5, 2025
#patent

September 1st is Disaster Prevention Day. I maintain a rolling stock of food for disaster preparation, and I found bread at a store which the expiration date is over a month. It’s sold by Komo Co., Ltd., headquartered in Komaki City, Aichi Prefecture. Unusually for bread, it’s also sold in vending machines and can be purchased at stations and airports. I see Danish pastries most often, but croissants and pies are also available.

Long-Life Bread

The reason for its long-term storage is reportedly the use of Panettone yeast, combined with minimizing moisture content to the absolute limit, which suppresses bacterial growth. I had assumed some additive was extending the shelf life, so learning it’s due to the yeast type makes me feel safe letting my kids eat it. When I actually gave it to my children, they said it tasted just as good as other bread with shorter shelf lives and ate several pieces.

Given its unique feature of an extended shelf life—something ordinary bread can’t achieve—I wondered if it held patents. Upon checking, I found it was indeed patented under Japanese Patent Numbers 1721291 and 2971634, though the patents have since expired.

Komo Co., Ltd. seems to be the pioneer and industry leader in long-life bread. As a local company, I want to keep buying their products to support them. Their goods are even being served at the ongoing Osaka-Kansai Expo! (Chamomile)

Summer Breakfast

August is coming to an end, but according to the weather forecast, it looks like the hot weather will continue for a while longer. With this kind of heat, it’s easy to skip breakfast, so this summer I’ve been making sure to eat cereal every morning.

This cereal was on sale at my regular supermarket. It’s from a well-known snack manufacturer. The back of the package has various information about nutrition and how to eat it. And there it was—the trademark text printed in small letters.

When I searched for “Frugra” on the J-PlatPat patent information platform, I found various registrations, including not just the product name but also the surrounding design elements. They’re protecting their valuable rights.

Irodori – Changing with the times and needs

  • August 20, 2025
#trademark

One of Nagoya’s classic souvenirs is “Morikuchi-zuke” from Yamatoya Moriguchi-zuke Souhonke, but the other day, I received a colorful small box of “Irodori.”

“Irodori” from Yamatoya Moriguchi-zuke Souhonke

I received ‘kyuri’ (cucumber) and “uri” (melon) Nara-zuke. Both Moriguchi-zuke and Nara-zuke are pickles made by marinating vegetables in sake kasu (sake lees). However, Moriguchi-zuke is made using “Moriguchi daikon,” a long, slender radish native to Aichi Prefecture, marinated in sake kasu and mirin kasu (sweet rice wine lees). Nara-zuke, on the other hand, is made by marinating various vegetables such as cucumber, melon, and watermelon in sake kasu.

Moriguchi daikon is a traditional vegetable of Aichi Prefecture, with Fuso Town in Aichi Prefecture accounting for about 70% of national production. It is a variety of radish with a diameter of 3–4 cm, a length of 120–130 cm, and some reaching up to 180 cm, and is registered in the Guinness World Records as the longest radish in the world.

I had always found the unique alcoholic flavor of Moriguchi-zuke and Nara-zuke off-putting, but I was drawn in by the vibrant packaging and decided to give them a try. To my surprise, they were surprisingly easy to eat and delicious. I wondered if my taste buds had matured (laughs), but apparently honey is added. They are cut into bite-sized pieces for easy eating and packaged in airtight containers to maintain freshness, which I also appreciated.

I was impressed by how traditional Japanese pickles have successfully adapted to the times and changing needs. I highly recommend giving them a try. The “Irodori” series also includes Moriguchi daikon, ginger, and bamboo shoots.

The distinctive design on the packaging, featuring the long, slender Moriguchi radish, is a registered trademark.

Can you find out in advance through trademark registration?!

On July 28, 2025, “Chiikawa Park” opened in Ikebukuro, Tokyo.
Chiikawa Park is an amusement facility themed around Chiikawa.

The information about this facility was made public about three months before the opening (at the end of April), but rumors had been circulating on social media since early April among fans.
Curious about how this information was discovered, I traced various posts and found that it was due to a trademark registration.

“Trademark?!” I was a bit surprised, but it made sense.
It seems that someone discovered the trademark “Chiikawa Park” (Japanese Trademark Registration No. 6948243) on J-Plat Pat and speculated about it. Additionally, on the same day, a trademark application with Chiikawa’s illustration was filed, confirming that it is indeed Chiikawa. (Japanese Trademark Registration No. 6948244)
While the designated goods or services do not specify an amusement facility, the name “Park” suggests it could be a park or amusement park.

Tickets for Chiikawa Park were distributed by lottery, so I applied, but unfortunately I was not selected. I plan to apply again if I get another chance.
Additionally, there was a lottery for a limited-time mobile Suica skin design to commemorate the opening, and I applied and won! It’s so cute! ♡

Donald here!

  • August 6, 2025
#trademark

I got some McDonald’s to go. On the paper bag, there was a picture of Ronald throwing trash in the trash can with an R mark next to it.

I looked it up on J-PlatPat and found that this illustration itself was trademarked. (Japanese Trademark Registration No. 5625449, Rights Holder: McDonald’s International Property Company Limited, Registered in 2013)

Ronald throwing trash in the trash can

The first trademark for Ronald’s illustration was filed in 1980 and is still in effect (Japanese Trademark Registration No. 1677689). Multiple trademarks have been registered for Ronald alone, with different poses.

Incidentally, the original English name of this mascot is Ronald McDonald, so it would be pronounced “Ronald McDonald” in English. However, since “Ronald” is difficult for Japanese people to pronounce, “Donald McDonald” was adopted. Japan McDonald’s recognizes both ‘Donald’ and “Ronald” as correct names. (Marron)

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.
