Entrepreneur

Serial entrepreneur since 2004. At NUS, developed an idea into a full scale startup company AYOXXA (www.ayoxxa.com) which now employs 25 people and closed its Series A and B venture funding round over a total of 20 million S$. AYOXXA won several prices and operates research offices in Singapore and Germany. Previous to NUS cofounded the biotechnology companies’ biognostic AG (www.biognostic.de) in Berlin, XanTec (www.xantec.com) in Münster, Germany. 

 

Inventor


Inventor of 13 patent families resulting in more than 70 patent applications of which 20 are granted and commercialized by different companies. He is also a co-inventor of Capsulution AG’s (Berlin, Germany) nano-and microencapsulation technology and drug delivery platform and for Supernova Ltd’s (Hong Kong) biolabeling technology. Dr Trau has extensive knowledge and experience in IP management including IP search, patent drafting, patent strategy, novelty and inventive step issues and patent licensing and commercialization.
