    CALGARY, Sept. 18 /CNW/ - AeroMechanical Services Ltd. ("AMA"), a leading
service provider of aircraft health performance monitoring systems, announced
today that the U.S. Patent Office has again confirmed the validity of AMA's
U.S. Patent No. 7,203,630, abruptly ending a reexamination proceeding
initiated by Star Navigation Systems Group, Ltd. (Star).
    Last year, as announced in AMA's September 26, 2007 press release, Star
requested the Patent Office to declare AMA's patent invalid in view of Star's
U.S. Patent No. 7,113,852. After a review, the Patent Office disagreed with
Star and summarily rejected Star's attack on AMA's patent, finding that AMA's
'630 Patent was valid as-issued.
    The Patent Office's ruling has dealt a significant blow to Star, because
it demonstrates not only the validity of AMA's patent but also the substantial
differences between AMA's products and Star's '852 Patent.
    The ruling completely undermines Star's ongoing patent infringement case
in the Northern District of California, where Star is alleging that AMA is
infringing Star's '852 patent. On September 3, 2008, Star re-filed for the
third time the infringement case in California. AMA filed a motion to dismiss
on September 17, 2008. The Patent Office's ruling further evidences that the
California lawsuit is without basis and that there is no merit to the
infringement allegations. AMA will continue to defend itself against the
baseless allegations made by Star.
    AMA is the technology leader in aircraft health performance monitoring
systems, and holds patents recognizing its innovation in this industry. AMA
takes intellectual property matters very seriously.
