Supress Products, Creators of Supress(R) Sound-Engineered Drywall, Defeat Serious Materials/Quiet Solution Claims of Patent Infringement

    SAN RAFAEL, CALIF., December 4 /CNW/ - Supress Products, LLC, announced today that it has defeated claims of
patent infringement asserted by Serious Materials LLC, dba Quiet Solution, in
federal court. In March 2007, Quiet Solution filed a complaint in the United
States District Court for the Northern District of California, action no.
C07-01328 RMW, alleging that Supress infringed multiple claims of U.S. Patent
No. 7,181,891 ("the '891 patent") and simultaneously announced that it would
"make every effort to delight any dealer, builder or contractor affected" by
the lawsuit against Supress. Supress denied the allegations, asserted
counterclaims for declaratory relief that the patent was invalid and not
infringed and vigorously defended the lawsuit.

    Conceding that its case had no merit, Quiet Solution stipulated to
dismiss its claims for patent infringement with prejudice and further agreed
that it would refrain from suing Supress and its distributors, customers or
successors, for infringement of the '891 patent on any product currently
marketed and sold by Supress. This lawsuit was the third Quiet Solution has
filed against Supress, and this is the third lawsuit Quiet Solution has

    "We are thrilled with the result we obtained in this lawsuit," said Bruce
Donaldson, President of Supress Products. "The result not only completely
vindicates our award-winning products in high-performance soundproofing, but
it also eliminates any concerns our dealers, builders or contractors may have
had based on Quiet Solution's claims surrounding the litigation," said Bruce
Donaldson. Donaldson continues, "Supress' Sound-Engineered Drywall products
are the best in the industry, bar none -- they obtain the best acoustic
results in the thinnest soundproofing wall construction and have no impact on
the drywall installation trade."

    Supress was represented in the lawsuit by Morgan W. Tovey and Jonah D.
Mitchell of Reed Smith LLP in San Francisco. Serious Materials/Quiet Solution
was represented by John L. Cooper, Jeffrey M. Fisher, June T. Tai and Cory M.
Mason of Farella, Braun & Martel LLP in San Francisco.
