Unterpremstaetten, Austria (21 May 2014) - ams (SIX: AMS), a leading
worldwide manufacturer of high performance sensor and analog
solutions, announces that the company has won a last-instance verdict
against Melexis N.V./SA (Belgium) in the patent validity lawsuit
launched by Melexis with respect to the European Patent EP 0 916 074
B1 covering magnetic field position sensor products.

The German Federal Supreme Court (Bundesgerichtshof) in Karlsruhe
(Germany) recently issued a final verdict validating the patent,
which is exclusively held by ams, and nullifying Melexis' claim that
the underlying contactless position sensor technology was not
patentable. ams had expected to prevail in the last instance of the
patentability lawsuit following its appeal of the first-instance
decision by the Federal Patent Court (Bundespatentgericht) in Munich
(Germany).

Given the patentability decision against Melexis the existing
first-instance verdict in the patent infringement lawsuit against
Melexis N.V./SA (Belgium) and its German subsidiary Melexis GmbH is
fully reinstated. This lawsuit covers magnetic field position sensor
products and European Patent EP 0 916 074 B1 and was brought before
the District Court (Landgericht) in Duesseldorf (Germany) by ams. As
a consequence, Melexis continues to carry the risk of financial
damages for patent infringement being awarded to ams on the basis of
the valid infringement verdict.

Bernd Gessner, Executive VP and General Manager Business Unit
Automotive at ams, commented: "We are delighted by the Federal
Supreme Court decision validating our patent which has been
exclusively held by ams since 2003. We are spending significant
amounts of time, effort, and money to develop the technologies
driving our products and will continue to vigorously defend our
intellectual property (IP) against unauthorized use or infringement."

ams is the worldwide leader in high resolution magnetic field sensor
solutions. ams' extensive range of rotary and linear position sensors
provides robust, contactless position measurement for virtually
countless applications.
