Zecotek Files Patent Suit

Photonics Spectra
Jun 2012
Zecotek Imaging Systems Pte Ltd., a subsidiary of Zecotek Photonics Inc. of Richmond, British Columbia, Canada, has filed a patent suit in the US against Saint-Gobain Corp. and Philips for infringing its US Patent No. 7,132,060. The patent covers the substances and chemical formulations used to grow lutetium fine silicate (LFS) scintillation crystals. The lawsuit alleges that Saint-Gobain’s LYSO crystals infringe Zecotek’s patent, and that Philips infringes by using those crystals in the positron emission tomography scanners it sells. Zecotek is joined by its exclusive licensee for certain LFS crystals, Beijing Opto-Electronics Technology Co. Ltd., as co-plaintiff.
