E-tak® Antibacterial Spray α

#patent #trademark

The other day, while watching a BS (Broadcasting Satellites) news program, I saw a commercial promoting “patented ingredient XX blended!” and “patent number XXX”. Perhaps it is an occupational hazard of working at a patent office, but I took note of it when I noticed it (laugh). It is a product called “Etak® Antibacterial Spray α” (Eisai). I did a little research and here is what I found out.

Since it was an Eisai commercial, I naturally assumed that it was patented by Eisai Co., Ltd. but when I looked up “Japanese Patent No. 4830075” on J-PlatPat, a patent information platform, I found that it was a patent shared not by Eisai but by Hiroshima University and Manac Incorporated.


Incidentally, the registered trademarks “Etak” (in katakana) and “Etak” are also owned by Campus Medico Co., Ltd. The company is a university venture that commercializes the results of research conducted at Hiroshima University’s Graduate School of Biomedical Sciences (the company’s website also lists Japanese Patent No.4830075 under “Patents held by our company,” but according to J-PlatPat, Hiroshima University and Manac Incorporated are still the patent holders).

This area is a little confusing, but on Manac’s special Etak website, in addition to Eisai, Kurabo Industries Ltd. and Jex Inc. is introduced in the “related products” page so it seems the three companies are licensed. It is difficult to understand the situation by browsing only the websites of the licensee companies, but this time I was able to confirm the information because it was introduced in a commercial along with the patent number and was also introduced on the websites of each company.

E-tak® Antibacterial Spray α is advertised as a product that “when sprayed on doorknobs, tables, or anywhere else you are concerned about, the long-lasting antimicrobial ingredient prevents the growth of viruses and bacteria in the sprayed area,” which sounds like it would sell well after the Corona disaster in 2020, but further research revealed that it had won the Nikkei Sangyo Shimbun Award for Excellence in the Nikkei Superior Products and Services Awards in 2018, before the Corona disaster. …Did you know about this?

Electronic Thermometer

#design #patent #trademark #utility model

My long-time electronic thermometer broke, so I bought a new one.
The built-in battery seems to have worn out, not only because of infection prevention measures, but also because my elderly family members have more opportunities to take their temperatures regularly.
Without time to do any preliminary research, I went to the sales floor of a local drugstore and was surprised to find several electronic thermometers available and surprisingly inexpensive despite their high functionality.

I remember that in the past, most thermometers did not have replaceable batteries to prevent infants from accidentally ingesting button batteries, but now they sell thermometers with replaceable batteries. I guess they have devised a way to prevent easy removal of the battery.
Some were waterproof and washable, which seems to be in high demand in this day and age, and some had an attached case that could be easily cleaned with alcohol.

After much deliberation, I chose the Terumo thermometer we had been using previously and purchased a thermometer with a sound pressure about twice as loud and easy to hear at the end of a temperature test. It can predict temperature in about 20 seconds and measure temperature as speedily as a temperature check at a hospital.

The Terumo logo in the image is naturally a registered trademark (Japanese Registration No. 6191923 Protective No. 01), but a further search on J-PlatPat revealed more than 250 patents, utility models, and designs for Terumo’s electronic thermometers.

By the way, Terumo thermometers have had a 100-year history. What is the 100th anniversary commemorative thermometer sold last year! If you are interested, check the following site♪ (Cacao)

A family member of one of our firm’s employees bought a lot of hanpen (fish paste) at “Nagoya Kamaboko Uomata,” which was introduced on TV. It was mentioned in the firm that the hanpen were delicious.

I looked up “Uomata” at work and found that it was the store for which we had registered the trademark.

“TRICK OR TREAT” Snack Package

  • October 12, 2022


It is October, and the end of this month is Halloween.
Although not as many as in the past, Halloween goods can be seen everywhere in town, reminding us that autumn has arrived.
The most familiar Halloween goods are the standard snacks sold in supermarkets and other stores. Illustrations of pumpkins, ghosts, witches, skeletons, bats, black cats, etc., are colored orange, black, and purple for Halloween. All of the cute illustrations are eye-catching.
Looking closely, it seems that many large bags of snacks are sold with Halloween illustrations. Just because the package design is different from the usual, it gives a fun and rich feeling.


Incidentally, the “TRICK OR TREAT” on the top of the package of the product introduced here was registered as a trademark, but the registration date is 47 years ago. I was surprised to learn that they had already registered a trademark related to Halloween nearly 50 years ago, when the word “Halloween” had not yet taken root. (Time)

Cooling Ring

  • October 5, 2022


Early this summer, my daughter asked me to buy her a cooling ring to wear around her neck, and I purchased the product shown in the photo.

Cooling Ring

Inside the ring-shaped tube is a liquid that freezes (becomes solid) at temperature below 28 Celsius. When placed in the freezer, etc., it solidifies quickly and stays cold.

Since it is used around the neck, it cannot cool the whole body, but my daughter says that the part of the body that touches the ring feels cool and comfortable.

By the way, the enclosed instruction sheet mentioned the patent number (Japanese Patent No. 6895671).
