Melexis Remains Confident About Outcome of Patent Lawsuit

IEPER, Belgium, May 20, 2010 /PRNewswire-FirstCall/ — On May 18th, 2010
the Regional Court of Dusseldorf, which is competent to rule on patent
infringement but not on patent validity, issued a first determination in
favor of austriamicrosystems in the patent infringement lawsuit against
Melexis (for your reference see also our press release dated March 16, 2009).
This ruling applies to the sales of the Melexis part number MLX90316 in
Germany.

Melexis remains confident in its initial position: The MLX90316 product
results from wholly owned proprietary patented technology and differentiates
by many means, especially the basic principle, from the austriamicrosystems’
patent.

Melexis will review the grounds for the judgment and will lodge an appeal
against it with the Higher Regional Court of Dusseldorf. Melexis is convinced
that its attacked product does not infringe the austriamicrosystems’ patent
and that the Regional Court ruled incorrectly.

In March 2009, Melexis initiated a claim to the Federal Patent Court in
Munich, the only competent German Court for judging the patent validity.
Melexis remains confident that this claim will demonstrate prior art and thus
will invalidate the austriamicrosystems’ patent. The Federal Patent Court has
scheduled a hearing on this nullity action for December 2010.
