Valentine’s Day History…U.S. Patent no. 7,000,000

Posted by innovativeip on February 16, 2011

Only five short years ago, on February 14, 2006, the seven millionth United States patent was issued to E.I. du Pont de Nemours and Company.  Although it would have been especially wonderful if the historically numbered patent had borne a subject matter of the heart, U.S. patent no. 7,000,000 is simply entitled, “Polysaccharide fibers”.  (Those so inclined can nevertheless stretch and consider the sugar monomers at the fiber core a tenuous link to candy hearts for this Valentine’s patent.)

Issued February 14, 2006, U.S. Patent no. 7,000,000
The real focus of this patent is the fiber’s desirable properties, and the manufacturing process that is a “green” improvement over those that depend primarily on petrochemicals.   These modified fibers for textile use are biodegradable, low cost, and are generated from renewable resources, such as corn.   Moreover, the properties are described as “cotton-like”, yet without the labor and land intensive requirements of cotton, or the inherent short fiber length thereof. 
Today’s Patent of the Day is reportedly the 33,801st awarded to DuPont, since its first in 1804.  Quite a record of innovation.  You can read the entire patent text at, and you can read about DuPont’s related products, such as commercial carpet and computer bags offered under the SORONA trademark , at Enjoy!
