(17 June 2011, Hong Kong) - Recently, Comba Telecom Systems Holdings Limited and certain members of the Group (the “Company”) have received a writ issued by the Beijing No. 2 Intermediate People’s Court in the People’s Republic of China from Andrew LLC (“Andrew”) for a civil litigation with respect to an alleged patent infringement by the Company. Pursuant to the writ, Andrew has initiated legal proceedings against the Company in relation to the alleged patent infringement for its RET Antenna and sought for an injunction and indemnifi cation of economic loss of RMB12 million and other expenses relevant to the litigation. Andrew has also claimed that it has initiated legal proceedings in Brazil in relation to the alleged patent infringement. The Company is now in proceed of undertaking effective measures in response to the alleged claims.

Andrew has initiated litigation on the patent infringement relating to RET Antenna. Based on the understanding of the Company, the patent had been void and cancelled in various regions.

In China, the patent of Andrew’s RET Antenna was declared void in 2007 and 2009 by the State Intellectual Property Offi ce and was also subsequently declared void by the Beijing Intermediate People’s Court in late 2010.
