Rational AG: Claim of patent infringement issued by Technology Licensing Corporation and Food Automation Service Techniques, Inc. in the USA

Ad hoc announcement transmitted by DGAP – a company of EquityStory AG. The issuer is solely responsible for the content of this announcement. —————————————————————————— Landsberg, August 23, 2006. The corresponding statement of claim was submitted to our subsidiary in the USA on August 21, 2006. Throughout the world and in all its industrial sectors, patent disputes are essentially not an unusual occurrence. Occasionally, we too must successfully defend our legal position by both active and passive means. From our standpoint, however, it is unusual for a claim of infringement to be publicized worldwide, as is the case with the press release issued by Food Automation Service Techniques Inc. (FAST) on August 22, 2006, practically simultaneously with their submission of the statement of claim. We are currently engaged in examining the statement of claim in detail, in order to be able to prepare an appropriate counter-statement. Our initial judgement of the subject is that the claims made will not prove to be sustainable.
