PRESS RELEASE 
 
25 February 2010 
 
 
            Offshore Hydrocarbon Mapping plc ("OHM" or "the Company") 
 
              European Patent Office Decision to revoke EMGS patent 
 
 
 
Offshore Hydrocarbon Mapping plc (AIM:OHM), notes the decision of the European 
Patent Office, announced 24th February 2010, to revoke a general method patent 
held by EMGS of Norway. 
 
The patent, EP 1256019, is an early general method patent describing CSEM for 
hydrocarbon detection.  The corresponding UK patent was revoked by the UK high 
court in 2009 (although this decision is being appealed by EMGS), and  this 
additional decision by the European Patent Office further strengthens the long 
held OHM view that such general method patents are invalid and unenforceable. 
 
The European Patent Office decision applies to European countries where the 
patent has been validated.  EMGS has two months from receiving the written 
decision of the European Patent office to revoke the patent in which to lodge an 
appeal against the decision.
