#design #patent

My child has become crazy about volleyball lately, partly due to the influence of the anime “Haikyu !!”. The ball we have at home is from Mikasa Corporation, and it seems to correspond to the Design Registration No. 1318937.

However, looking at Mikasa’s homepage, it seems that the one with design registration No. 1574960 is currently the mainstream. The one with this design also had a “patent registration” label. When I searched with J-PlatPat, I found some patents of Mikasa Corporation. I was not sure which patent corresponded to this volleyball, but I realized once again that the things that children use on a daily basis are also supported by intellectual property. (Marron)

para gel

  • March 31, 2021


I like decorating my nails as part of fashion. I used to apply manicure myself, but now it is my monthly pleasure to get my gel nails done at a nail salon.

Gel nails are nails that are formed by scraping the nails and curing the gel-like resin. There are various types of gel nails, but the “para gel” I use can be used without scraping the nails, so you can keep your nails clean.

“Para gel PROFESSIONAL NAIL” was registered as Japanese Trademark Registration No. 5359996 on October 8, 2010.
I am happy to find a trademark that is familiar to me as one of my pleasures. (Rabbit)

Anniversary associated with Intellectual Property

  • March 24, 2021

#intellectual property #patent #patent attorney

The theme is “Introduction to Intellectual Property”, but today I would like to introduce anniversaries related to intellectual property.
First, I would like to ask you a question. How many do you know?

April 18, Invention Day (Japan)
April 23, World Book Day / Copyright Day (UNESCO)
April 26, World Intellectual Property Day (World Intellectual Property Organization)
July 1, Patent Attorney’s Day (Japan)
July 22, Copyright System Day (Japan)
August 1, Aichi Invention Day (Aichi Prefecture)
August 14, Exclusive Patent Day (Japan)
November 18, Music Copyright Day (Japan)

It seems that there are many anniversaries in April and the hot season for some reason. Looking overseas, there is Inventor’s Day. In the United States, for example, Thomas Edison’s birthday is Inventor’s Day.

April is coming soon. This year too, the day of invention, the day of world intellectual property rights, will come. In Japan, every year, one week including Invention Day is designated as Science and Technology Week. It may be a good idea to think about inventions and science in this season when the weather is getting better. (blink)

Work experience at a patent office

  • March 19, 2021

#intellectual property #patent #patent attorney

At KidZania Tokyo, where children can experience work, “patent office” will open for a limited time!
This is a limited event from March 19th to 25th during “Patent Attorneys Week” held by the Japan Patent Attorneys Association and the planning and management company of KidZania.
It will be the first time that a work experience of a “patent attorney” has appeared in KidZania.
Participant will become a “patent attorney”, receive a request from the “invention workshop”, create patent application documents as an agent, and confirm the examination result at the “patent office satellite office”. A registration certificate will be issued, and the participant can take it home as a deliverable.
As a person working at a patent firm, I hope that children will have fun learning about intellectual property and the role of patent attorneys. (Cacao)

Fun for snacks

  • March 10, 2021


The other day, I watched a documentary on TV about a woman involved in product development at Koike-ya Co., Ltd. The next day, I stopped by a convenience store in front of the station on my way home from work to buy the snack which was introduced since I felt the enthusiasm in the development, but it was sold out.

The influence of television is amazing. After that, it was available several days later. I felt the commitment and it was delicious.
Looking around the convenience store, you will find snacks with various tastes on sale, which makes you feel happy.
Catchphrases such as “limited”, “takumi” (craftsmanship) and “adult” (used for products which has an acquired taste) makes me lose my temptation and I can’t resist to buy it.
When I searched for Koike-ya on J-PlatPat, I found that 13 to 25 applications were filed annually for trademarks alone. Some names such as “New Normal Snack” and “LONG LIFE ∞ SNACK ∞ 湖” (湖 is “Ko” for “Koike-ya”) seem to reflect the era just by hearing them.
You can see the effort they are putting into their method of selling. I hope that they will continue to make products that will entertain us consumers. (Marigold)

The other day, when I was looking at the JPO public relations magazine “Tokkyo”, published on February 5, 2021, I found a product that caught my eye.
Its name is “Nekojasuri”.

This product is a file for cats to groom that was made to resemble the texture of cats’ tongue. It was made based on the tool manufacturing technology, developed by Wataoka Co., Ltd., a long-established file maker in Kure City, Hiroshima Prefecture, which has been in business for over 120 years.
How flexible the idea of the person who developed it is to associate the tongue of a cat with a file. I envy the person with such an inspiration.

Soon I bought it and gave it to my cat. Meow ❣

My cat is not usually a sweet type, but it is rubbing its head on the file.
It might be of a feeling that cannot be obtained from human hands. (Time)

[Japanese Patent number] No. 6698985

[Title of Invention] Massage device for pets

Tube container patent

  • February 24, 2021


Hello. This is Hiro.
I bought wasabi in a tube container, made and sold by S&B Foods Inc., with the patent number displayed.

When you open the cap, you can see that the shape around the screw part of the container and the inside of the cap have some designs to them.

Thanks to the locking part, it is difficult to loosen when the cap is closed, and it will not open without permission. Also, thanks to the screw part divided into four in the circumferential direction, it can be easily opened with a slight twist of the cap. In addition, the vertical grooves make it easy to crush the tip of the container and squeeze out the wasabi.

By the way, the problem to be solved by the invention of Japanese Patent No. 660532 is, “Compared to the conventional invention, the impact of outward convex of the container body constituting the loosening part just before overcoming the inward part of the lid is to be made stronger and the force required for this is to be increased. Furthermore, the distance to be overcome is shortened, thereby making the clearer feeling when the lid is closed.” Certainly, when you close the cap, you can clearly feel that it is closed.
I am surprised that such tube containers, which have been around for a long time, have been improved and made easier to use.

The detailed contents of this patent can be found at the link below (J-PlatPat).

Toge no Kamameshi

  • February 17, 2021

#trademark #utility model

The other day, I went to the “National Ekiben (Lunch Box sold at train stations) Fair” held at a grocery store near my house and purchased “Toge no Kamameshi” lunch box.
“Toge no Kamameshi” is an ekiben sold at Yokogawa Station in Gunma Prefecture, where ingredients such as quail eggs, chestnuts, and burdock are put on rice cooked with kelp (seaweed) and secret soup stock. It’s a very delicious lunch box that you will never get tired of eating many times.

As shown in the photo, the trademark registration number (No. 1731043) and the utility model registration number (No. 3094454) were found on the wrapping paper, so I searched for them with J-Platpat.

Regarding the trademark right, the vertical writing “Toge no Kamameshi” was registered as a designated product “Kamameshi”.
On the other hand, the utility model right was registered as the title of the device, “Kamameshi container”, which is “related to the Kamameshi container that can be effectively used as an air freshener container after being used for its original purpose”. The utility model right has already expired, but you can see the contents on J-Platpat, so if you are interested in what it was, please search. (Sakuramochi)

“KIYOSU” (Whiskey)

  • February 15, 2021


The other day, I saw an advertisement for a whiskey named “KIYOSU” in the subway train. It is manufactured and sold by Kiyosuzakura Brewery Corporation. The company is located in Kiyosu City, which borders Nagoya City. Speaking of Kiyosuzakura Brewery, “Kiyosu Castle Nobunaga Oni Koroshi” is their famous sake, but they also make whiskey, vodka, and gin as well.

When I searched for “Kiyosuzakura Brewery” on J-PlatPat, 4 Japanese registered trademarks including ” KIYOSUJONOBUNAGA ” came up.
Japanese whiskey is one of the world’s five major whiskeys and is so popular that some brands are running out of stock. In addition, craft gin, which is flavored with botanical ingredients peculiar to the production area, is becoming more popular because it has a strong character. Both are interesting liquors. I would like to try it once. (Syszo)

Trademark “Fist” (“Right”)?

  • February 3, 2021


(拳(ken) = fist, 権(ken) = right)

There is a page on the JPO homepage that introduces business trademark interestingly.

(Japanese JPO homepage of introduction of business trademark)

There is a video on this page which introduces a seemingly weak president who got his company’s trademark imitated and learns the mystery of “Trademark Fist (Right)” to protect the company’s important rights.
