Patent application filed a year and a half ago

  • 2021年09月29日


When a year and a half is passed since the filing of a patent application, a publication bulletin is issued, and everyone can know the contents of the application. It was on January 16, 2020 that the first infection of the new coronavirus was confirmed in Japan. After that, the latter half of January and February 2020 was the beginning of the Corona disaster. A patent from just that time has recently been published. (As of September 16, 2021, patent applications with filing dates up to around March 6, 2020 have been published, with exceptions such as early publication.)

So, I checked to see if there were any patent applications that were the first to describe terms such as “Three Cs,” “Social Distance,” “refrain from going out,” “stay home,” and “unnecessary and nonurgent,” which have come to be used a lot in the Corona disaster, but I could not find any. Based on the tendency of utility model bulletins to be published within three or four months of filing, we can guess that corona-related terms began to be included in application specifications probably from applications filed around April 2020.

So, when I was looking at the search screen to see what applications had been filed around February 2020, I happened to see an application by GURUNAVI INC. for “information processing system, information processing method, and program”. GURUNAVI INC. is a company that operates the GURUNAVI website, which accepts restaurant reservations and delivery orders.

GURUNAVI INC. has been consistently filing patent applications related to information processing for some time now; from 2017 to 2019, the company filed about 70 applications per year, an average of 5 to 6 per month. In contrast, I was curious to see that 12 applications were filed in the month from January 23 to February 21, 2020, which is double the average of the previous year. It may not be directly related to Corona, but was there any strategy behind it? I can only guess now, a year and a half later, that each company must have been thinking of various strategies in the early days of the Corona disaster. (Conan)

The technology of deliciousness

#patent #trademark

I like Ichimasa Kamaboko’s “Karikko” snack series, and whenever I see them at the supermarket, I can’t resist buying them. The texture is chewy and hard, and I can’t stop eating them. There are three types: sardine (Karikko Iwashi), shrimp (Karikko Ebi), and seaweed & hijiki seaweed (Karikko Wakame&Hijiki), but sardine is my favorite.

Karikko Iwashi

On the back, there is a patent number for the manufacturing method. (Japanese Patent No. 3816037)

Karikko Iwashi

I felt that the crunchy texture with the flavor of fish is supported by this kind of technology.
In addition, “Karikko Iwashi” and “Karikko” have been registered as Japanese trademarks.

This product is often found in supermarkets, not in the confectionary section, but in the section where fish paste and fish sausage are sold, so if you are curious about it, please look for it. (Marron)

Dynamic Random Access Memory (DRAM)

  • 2021年09月05日


Today, I would like to introduce an invention related to September 5. What I will introduce this time is dynamic random-access memory (DRAM) devised by American electronical engineer and inventor Robert H. Dennard (1932.9.5 ~). Today, September 5th, is his 89th birthday.

DRAM is a type of semiconductor memory. It has the disadvantage of constantly consuming power for refreshing (memory retention operation) because information is lost when it is discharged, but it is widely used in computers’ main storage devices, digital televisions, and digital cameras, etc. due to its large capacity and low cost.
Currently, all the main storage devices of computers are DRAM. In recent years, DRAMs that specialize in low power consumption have also appeared.

The DRAM we use every day was conceived by Dennard in 1966 at IBM Thomas J. Watson Research Center. The following year of 1967, a patent application was filed, and it was registered in 1968 (US3387286A). Dennard also won the Kyoto Prize in 2013.

By the way, IBM Thomas J. Watson Research Center is a research division of IBM. In addition to Dennard, it is known that many prominent scientists such as Benoit Mandelbrot in mathematics and Leo Esaki in physics also worked there.

Local Sake Handago

#design #patent #trademark #utility model

The other day, I found an advertisement that caught my attention. The words “Thanks to you, we’ve won first place in the U.S.” drew my attention, and upon closer inspection, I realized that it was a sake that had won the Grand Prix at the American Sake Competition.


I checked my local supermarket to see if they had it, and luckily I was able to purchase it.


Drinking well-chilled sake on a hot day is the best. Eating it with refreshing somen noodles made it feel like summer. It was a well-balanced sake, not too heavy and not too light. A search of the J-Plat Pat database for Nakano Sake Brewery Co., Ltd,, the maker of Handa-Go, revealed a total of six patent and utility model applications, one design application, and 207 trademark applications, including Handa-Go. The number of trademarks is overwhelmingly large, and I wondered if the company was developing its business with a strategy to increase its brand power.

I was a little excited to find out that there are many delicious local delicacies that have yet to be discovered. (Marigold)

Resin Accessories

  • 2021年07月21日


An old friend of mine has been making accessories with UV resin.
UV resin is a special resin solution that hardens under UV light.
After pouring the UV resin solution into a mold of your choice, you can put your favorite small objects in the mold, or you can color the UV resin solution itself and then expose it to UV light to harden it into your original accessory.

Even though it is just a resin solution, if you look into it, you will find that different manufacturers have different technologies, such as ease of hardening, blending with inclusions, durability, etc. that Patents for manufacturing methods have been applied.
There are many kits available at general stores and stationery stores in town, and you may see them, but I feel that it is a very deep world where the sense of the creator is important because it is easy to make. (Swimmer)

Easy Note

  • 2021年06月02日


Shortly after the beginning of the new semester, I found one of the teaching materials that my child brought back from school that said, “patented product”. On the front cover, it was labeled “Repeating Keisan Drill Raku Raku Note(Repeating Calculation Workbook Easy Note)”, and a nostalgic illustration of “3-chome Tama” on it.

I wondered what kind of content was in the patent on the notebook, so I looked it up on the familiar J-Plat Pat, and the summary said, “To provide exercise notebooks and problem practice materials that allow students to learn how to properly write and use notebooks by solving problems using problem workbooks.”

I looked through the contents of the workbook, and even in them, I could see the ingenuity that went into making it easy for children to learn and write. I was impressed that this was a great invention, and I was reminded again that there are various forms of invention. (Marigold)

Support your new life

  • 2021年04月14日

#patent #trademark

From March to April, the phrase “new life support” are often seen in electric appliance shops and home centers. Not only when you move to a new land, but also when you commute from the same home as before, if your school or workplace changes, you will start a new life. You need products and services to support your new life.

Nitori Holdings Co., Ltd., a furniture and interior company, applied for the picture trademark below in October last year (2020) (Japanese Trademark Application No.2020-32144), and is awaiting examination as of the end of March 2021. I saw it used for store shelves and leaflets.

In addition, when I searched for “new life” in the patent as a keyword, I found the invention of “real estate information providing device” (Japanese Patent No. 6626166). It is to appropriately provide property information that meets the needs of users. In paragraph [0047], it is written “In addition, the user selects the requirements that he / she wants to emphasize, the requirements that he / she wants to have, the requirements that he / she thinks are indispensable for his / her new life, and the requirements where he / she seeks comfort in a new way of living.”

I think starting a new life in the corona crisis is more anxious than usual, but there are various new life support products and services around. Why don’t you use them effectively? (Conan)

#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)

Anniversary associated with Intellectual Property

  • 2021年03月24日

#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

  • 2021年03月19日

#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)
