Comba Telecom Wins the Remote Electrical Tilt Patent Cancellation Case Against 
Carlyle Group Subsidiary CommScope With No Chance of
China's Patent Office Makes Final Decision and Completely Revokes the
CommScope's Antenna Patent 
HONG KONG -- (Marketwire) -- 02/14/13 --  Comba Telecom Systems
Holdings Limited ("Comba Telecom" or "the Group") (HKSE: 2342), a
leading global wireless enhancement solutions provider, has won an
antenna patent lawsuit against Carlyle Group subsidiary CommScope,
Inc., ("CommScope") where the patent was irreversibly cancelled in
In the legal action by Comba Telecom against CommScope and its
subsidiary Andrew LLC ("Andrew") to invalidate the antenna-related
patents in China, the Beijing High People's Court and the Patent
Reexamination Office of the State Intellectual Property Office
("Patent Reexamination Office") revoked the patent on remote
electrical tilt (RET) technology used in base station antennas as
asserted by Andrew in the litigation. The ruling by the Patent
Reexamination Office was final and conclusive, and CommScope no
longer has any avenues to appeal.  
The ruling echoes similar cases against CommScope and Andrew: other
antenna vendors have successfully applied for the cancellation of
Andrew's RET patents in Europe where Andrew's appeal was rejected and
the patents finally revoked by the European Patent Office in November
RET systems is a core technology that enables operators to control
the antenna beam. While phase shifters are a component of the RET
system, there are many different technological designs and Comba
Telecom has long deployed its own proprietary phase shifter
technologies. It holds at least 10 granted phase shifter patents and
multiple pending patents around the world including China, USA,
Brazil and Europe. These technologies are the results of intensive
R&D programs in which the Group invests considerable resources and
effort in order to maintain its competitive edge.  
In response to CommScope's statement on 4 February 2013, Comba
Telecom takes the position that CommScope's patent infringement case
on phase shifter technology is without merit and has appealed the
court decision and the decision has not become effective yet and the
litigation process is still ongoing. Furthermore, based on the
relative small amount of the damages, the Group does not consider
that there will be any material implications on the Group in respect
of such litigation and court decision. 
Mr. Tony TL Fok, Chairman of Comba Telecom, said, "The litigation by
CommScope with respect to phase shifters focused on two models of
antenna only for China that was discontinued some time ago due to
natural evolution and development of technology. While the effect of
this is minimal on our portfolio of antenna offerings, the Group will
nonetheless continue to pursue this matter through the courts. We
have a strong respect for intellectual property rights and will take
steps to defend and uphold our rights."
