Durel has become the world's largest maker of electroluminescent lamps using metal oxide-coated phosphor particles based on patented electroluminescent phosphor
technology exclusively licensed to it by 3M.
The PC sheet is bonded with adhesive to an electroluminescent phosphor
film that is in turn adhesive-bonded to a substrate of aluminum, or other material.
Durel pointed out that an oxide coated electroluminescent phosphor
having all the characteristics recited in claim 29 of the Sylvania EPO patent, is disclosed in a 1968 printed publication prepared for the United States Air Force known as the "Thompson report," Air Force Technical Report AFF-DL-TR-68-103.
SUMMARY: Durel is sued during trade show for patent infringement involving an electroluminescent phosphor
it was displaying for sale in Germany.
The legal action involves a type of small-size electroluminescent phosphor
, for which the company received a patent in 1997.
Part 3, the bulk of the book, details methods for electron beam activation of reactions at solid-liquid interfaces, with chapters on modification of fillers for cements, activation of aqueous phase at cement and concrete solidification, activation of reactions at solid-solid interfaces, modification of electroluminescent phosphors
, and electron beam modification of polymers.
Patent Suit Relates to Encapsulated Electroluminescent Phosphors
We feel vindicated as the lower court's finding was based on erroneous rulings," said Robert Fillnow, vice president and general manager of Chemical & Metallurgical Products, a leading manufacturer and global supplier of electroluminescent phosphors
The award was based on Sylvania's infringement of patents covering metal oxide coated electroluminescent phosphors
and processes exclusively licensed to Durel by 3M, one of its parent companies.
Since 1995, when Durel initiated the lawsuit, Sylvania has continued to make encapsulated metal oxide electroluminescent phosphors
, and has sold these products to Durel's competitors.
Since 1995, when Durel initiated the lawsuit, Osram Sylvania has continued to make encapsulated metal oxide electroluminescent phosphors
using Durel's technology, and has sold these products to Durel's competitors.
