CDT Acquires Important New Patent Portfolio
Monday February 13, 8:00 am ET
CAMBRIDGE, England, Feb. 13 /PRNewswire-FirstCall/ -- Cambridge Display Technology (CDT) (Nasdaq: OLED - News) announced today that it has acquired an important portfolio of patent rights from Maxdem Inc. The portfolio includes five US patent applications and their foreign equivalents relating to new light emitting polymer compositions and applications. The deal also includes a license to a large number of patents / applications relating to polyphenylene polymers and other polymer compositions and purification methods. These are expected to be useful in future materials improvements.
The acquisition will also strengthen what CDT believes to be its already dominant patent position in solution processable OLED materials and devices.
Included in the acquisition from Maxdem is a patent application for the invention of phosphorescent compositions containing a critical class of polymer materials in combination with metals / metal ions. CDT believes this provides a fundamental position in the use of conjugated polymers to achieve high efficiency phosphorescent emission in solution processable devices, whether for ink jet printing or any other means of solution processing.
In due course, the acquired rights will be transferred to Sumation(TM), which will incorporate this new technology into its materials development activity. Sumation has shown remarkable progress in materials performance since CDT formed this joint venture with Sumitomo Chemical in November 2005.
Notes:
1. CDT believes that any solution processable material whether fluorescent
or phosphorescent will require the use of conjugated polymers and will
therefore fall within its fundamental patents. In addition, CDT also
holds the important patent rights on the use of dendrimers in OLEDs,
and holds licensing rights to the key Seiko Epson patents relating to
ink jet printing in relation to any OLED containing a conjugated
polymer. With the Maxdem acquisition, CDT believes that it will now be
able to control the use of metal / metal ions in combination with key
polymers.
2. CDT notes that UDC has recently announced the grant of its US patent
No. 6,982,179, titled "Structure and Method of Fabricating Organic
Devices". CDT believes that this patent is limited to standard methods
of creating patterned multilayer devices by solution processing, such
methods being fully described in prior patents belonging to CDT or
within its control.
About CDT
Cambridge Display Technology is a pioneer in the development of light emitting polymers (P-OLEDs) and their use in a wide range of electronic display products used for information management, communications and entertainment. P-OLEDs are part of the family of organic light emitting diodes, or OLEDs, which are thin, lightweight and power efficient devices that emit light when an electric current flows. P-OLEDs offer an enhanced visual experience and superior performance characteristics compared with other flat panel display technologies such as liquid crystal displays, and have the key advantage that they can be applied in solution using printing processes. Founded in 1992, the company is headquartered in Cambridge, UK and is listed on the US Nasdaq National Market under the symbol 'OLED'.
