Press Release 

25 January 2012




("DATONG" or "the Company")


Result of Patent Litigation


DATONG PLC (DTE.L), a leading provider of covert intelligence gathering solutions, announces that, further to previous announcements that DATONG has been subject to a patent infringement claim, the Court of Appeal has judged that the patent in suit is invalid.

Since 2006, the Company has been a party to court proceedings in which MMI Research Limited ("MMI") alleged that a Third Party product for which the Company acts as a reseller infringes the UK element of a patent that MMI jointly owns. The proceedings were brought against the Company's supplier and the Company (the "Defendants") by virtue of its reselling activities.

The judgment was delivered by the Court of Appeal on 24 January 2012 who held that the patent in suit is invalid. The patent will be revoked and no damages will be payable by the Defendants under the claim.


As disclosed in the Company's annual report and accounts, a provision for £0.30 million is currently being carried in respect of the expected share of costs and damages to be borne by the Company for the sums that may have ultimately become payable.  As a result of the judgment, damages will not be payable by the Company.  The court has still not ruled on the amount of costs that will be payable by either the claimant or the Defendants and a further hearing may be required to determine the amount of costs.  In the event that the Company is required to pay any costs at all, these are expected to be substantially lower than the level of the provision.


Paul Lever, Non-executive Chairman of DATONG commented: "We are delighted with the outcome of the judgment of the Court of Appeal today.  There are no restrictions on DATONG's ability to sell any of these Third Party products into our chosen markets and the judgment removes any lingering doubt that may have existed.  The Company looks forward to continued success from this area of the business."
