news digest ♦ LEDs are entirely without merit.


Intematix is confident that its red nitride products do not infringe any valid claims under Mitsubishi’s red phosphor Korean patent. Intematix intends to vigorously defend itself against any such claims.


In addition, Intematix believes that the Mitsubishi patent is invalid and intends to commence an invalidation proceeding against Mitsubishi.


Mitsubishi Chemical sees red on phosphors


The firm has filed infringement for its nitride red phosphor patent ; these materials can be used in LEDs, lighting equipment, image displays and other goods


On December 20th, 2011, Mitsubishi Chemical Corporation (MCC) filed an infringement lawsuit in Seoul Central District Court against U.S. company, Intematix Corporation and Korean distributor, GVP, to prevent them from importing and selling MCC›s phosphor products.


MCC claimed that they have infringed a red phosphor patent in Korea (No. 816693) which is owned by MCC and the National Institute of Material Science.


The Korean patent No. 816693 relates to a nitride-type red phosphor commonly known as CASN and SCASN ( with a general chemical formula CaAlSiN3:Eu). The phosphors can be used in LEDs, lighting equipment, image displays and other goods where this type of phosphor is required.


MMC says CASN and SCASN are the only red phosphors to be used in LEDs due to high brightness and reliability.
