Hui Leng Tan

Senior Patent Attorney Singapore

About Me

I work as a senior patent attorney in Bird & Bird's Intellectual Property & Technology Group in Singapore, where I specialise in life sciences. I work with a broad range of clients, from local SMEs to foreign MNCs.

As a registered Singapore patent agent, I have considerable experience in patent prosecution, including the pre- and post-filing stages, in Singapore and internationally. I am also experienced in other aspects of patent related work, including 'freedom-to-operate' search and analysis, the preparation of third party observations, the preparation of infringement and validity opinions and advising on matters involving patent declarations related to therapeutic product licenses in Singapore. I am also actively involved in patent revocation and patent infringement matters, which include pharmaceutical and medical device related patents.

You'll find me listed in Who's Who Legal: Patents 2016, 2017 and 2018. I am also a member of the Examination Committee which sets and marks the papers for the Singapore Patent Agent Qualifying Examination. I am also a member of the Association of Singapore Patent Agents. Before joining Bird & Bird, I practised in a leading law firm and worked with a diverse array of clients both in Singapore and internationally.
  • As a senior patent attorney, my work mainly focuses on patent protection, for example, advising clients on strategies to maximise their protection in the various countries. One way in which I do so is by working closely with our international colleagues and associates to better understand their laws and requirements in order to provide relevant advice.


  • I graduated from the National University of Singapore (NUS) with a Bachelor of Science degree with a major in Biochemistry and a minor in Computer Programming and Applications. I also obtained a Graduate Certificate in Intellectual Property (IP) from NUS and subsequently, a Masters of Science degree in IP Management from the University.


  • I have been certified by Fédération Internationale des Conseils en Propriété Industrielle (FICPI) under the South East Asian Drafting Course.
