absorbent patent activity. - absorbent
Recently issued patents reflect the growth trend of ordinary ratherthan applications --
Specific patents; P&G, K-
C. move on, while the patent activity recorded in the weekly patent bulletin only reflects the possibility of the market and its future direction --
Of course, it is not the commercial nature of each patent authorization.
In fact, the number of patents related to non-woven and absorbent products has remained high for many years, which continues to bode well for the future of the industry.
In fact, the number of patents granted has declined in the past few years;
For example, in 1987, the non-woven industry reviewed 75 patents within six months.
This review only includes 62 patents issued in about a year.
However, although the total number of patents that were finally issued dropped by 59%, the total number of patents remains considerable compared to other industries.
Logically, at some point, the number of patents for absorbent products has to decline;
In fact, there are still so many patents appliedand received-
More important consideration.
This year's patent investigation also reflects an increasing trend towards a more general "absorbing items" or "disposing" of patents rather than applying --
Patents for specific "baby diapers" or "sanitary napkins.
The survey also does not include more than 10 patents issued for more general "non-woven" or "structures" that do not specifically refer to absorbent products, but may have applications in these areas.
Interestingly, most of these patents are for many
Layer or composite structure.
Among the manufacturers of absorbent products, Kimberly-
Clark, P & G in Dallas, Texas, and Cincinnati, OH, there are a few others though --
Including two Japanese companies.
This leading edge is approaching. The "Who" -
In this year's patent review, companies that reflect the vagaries of the patent scene of water-absorbing products are worse than companies that last year's individual companies participated in.
This year, Procter & Gamble, a one-time baby diaper maker for "Pampers" and "Luvs", took the lead in 11% patents and remained stable last year.
However, Kimberly, the manufacturer of "hug-
Clark won only 4% patents last year, but this year rebounded with nearly 10% patents, maintaining close ties with P & G.
Interestingly, most patents for both companies are generic "disposable diapers" or "absorbing products" patents with or without further descriptive features.
The only exception is an app
Specific adult incontinence patients are suing P & G.
Japanese manufacturer Uni-
Charm also owns nearly 10% patents;
Last year, the company also held the only patent review of training pants.
Kao, also located in Japan, has obtained 7% patents, which makes Japan a competitor with the most patents from countries outside the United States. S.
3 m, St. , manufacturer of Diapercomponent, also registered 7% patents
Paul, MN and personal products company in New Brunswick, New Jersey.
However, if chicopee, the sister company of the personal product (
Now Johnson & Johnson advanced materials company)
The number of personal products jumped to nearly 10%, including that.
The only European company on the list is molnlycke/Peaudouce, and 3% of the patents have been issued.
Interestingly, however, Hoechst AG in Frankfurt, Germany is known for its participation in the roofing and other industrial non-woven markets and has been granted a patent for "tampon and its manufacture.
Compared with last year, 32% of patents were granted to companies or individuals outside the United States. S. -the U. S.
Has the highest percentage of patents, 73%.
Japan won second place by virtue of a patent issued to Uni
Charmand Gao, 16%.
Europe won third place with 7% patents;
Taiwan, Australia and South Africa have obtained 1% patents, respectively. The "What" -
For patents issued above, the vast majority of patents issued are aimed at ordinary absorbing items that may or may not include a variety of "fancy things.
"Specifically, 56% of patents fall into this category.
This can be broken down into 38% describing absorbing items or disposable clothing, and 18% describing some sort of disposable diaper.
To further break this down, 29% of the 56% products in this category in the "absorbing items" area describe simple absorbing products;
The other 71% describes a "absorbing product ". . .
Similarly, in the disposable diapers category, 27% of disposable diapers are patented/73% disposable diapers. . . (
Full list of all patents issued, see the side bar attached).
Of all the patents issued, less than 1% of the patents describe infant diaperconstruction;
The patent was issued to a person in Australia.
The performance of adult incontinence products is slightly better, 3% of patents are prosecuted, and 16% of patents for health protection products (
Of these 16%, 20% were cotton strips).
Patents have also been issued for components of absorbent products including adhesive tape and adhesive.
Four specific categories
Paper urine film, tape, adhesive and high absorption parts
In total, almost 15% of patents were granted.
In the "other" category, a patent has been issued for the "non-woven fabric wiping immersion composition" and two patents have been issued for absorbent products used in the food transportation or packaging industry.
