Six Greenpeace activists - including comms director Ben Stewart - were last week cleared of causing criminal damage during a protest at the coal-fired power station.
The energy firm believes it is safe because the public are not aware that the company owns the power station.
E.ON PR and media relations manager Jonathan Smith referred to an Ipsos Mori survey carried out following the climate camp protests in August, which revealed that only four per cent of respondents knew that E.ON owned Kingsnorth.
'It is actually disturbing that so many people do not know we own it,' said Smith.
E.ON is not planning any PR activity relating to the court case. The firm retains Edelman for PR and public affairs.
Edelman UK CEO Robert Phillips called for 'ongoing constructive engagement between business and NGOs' instead of publicity-seeking protests.
