Dear sir

We write to clarify some rumours about the product and trade mark ownership of BioEm.

With the attached documents, it proved that CTG, the parent company of BioEm Air Sanitizing Technology Co Ltd, is the legitimate owner of the patent and trade mark of BioEm.

We regret to have such malice of slander by one of our competitors. We reported the case to the Police of Hong Kong and the Hong Kong Customs with the case (#1903011008338 and #2019.3.1: 12:01) respectively.

We do apologise for such inconvenience caused.

Yours faithfully


Sammy Tsui
Chief Executive Officer
BioEm Air Sanitising Technology Co Ltd
