Zecotek Files Patent Lawsuit Against Saint-Gobain Corporation and Philips

SINGAPORE, Feb. 23, 2012 /PRNewswire/ – Zecotek Photonics Inc. (TSX-V: ZMS) (Frankfurt: W1I), a developer of leading-edge photonics technologies for medical,
industrial and scientific markets, today announced that its subsidiary,
Zecotek Imaging Systems Pte Ltd., has started legal action in United
States Federal District Court in Los Angeles against defendants
Saint-Gobain Corporation and Philips for infringement of Zecotek’s U.S.
Patent Number 7,132,060.  Zecotek’s patent covers the substances and
chemical formulations used to grow lutetium fine silicate (LFS)
scintillation crystals which are characterized by their combined high
light yield and ultra-fast decay times and are typically used in
medical scanning devices.  The lawsuit alleges that Saint-Gobain’s LYSO
crystals infringe Zecotek’s patent, and that Philips infringes by using
those crystals in the PET scanners it sells.  

“We believe that this patent is fundamental, and that damages are very
substantial,” said Dr. A.F. Zerrouk, Chairman, President, and CEO of
Zecotek Photonics Inc.  “Our management, engineers with its principal
scientists Drs. Alexander I. Zagumennyi and Yuri D. Zavartsev, world
leading crystal scientists and members of the Institute of the Russian
Academy of Sciences, have invested significant resources in the
development and commercialization of our LFS scintillation crystals,
including our ultra-fast Ce:Ca:LSO/LYSO scintillators.  We have spent
many years of hard work to develop and secure this unique crystal
technology.   We are determined to vigorously enforce our intellectual
property rights to recover damages afflicted on Zecotek and the lost
value to our shareholders”.

U.S. Patent # 7,132,060 covering Zecotek’s LFS scintillation crystals
was granted on November 6, 2006.

Zecotek is joined by its exclusive licensee for certain LFS crystals,
Beijing Opto-Electronics Technology Co. Ltd., as co-plaintiff.  Zecotek
is being represented by Thomas Loop of the law firm of Graybeal Jackson
LLP and Justin Nelson of Susman Godfrey LLP.  Both firms are recognized
leaders in patent law and intellectual property litigation matters.
