About Us

Letters & Thoo was established in 2013 by founding partners Timothy Letters and Laurence Thoo, both professionally qualified and registered patent and trade mark attorneys, after many years of professional experience practising at leading IP firms in Hong Kong and Australia.

Our patent attorneys have established a proud track record of excellence in the field of IP having been consistently recognised by industry benchmark publications including International Asset Management (IAM) magazine’s The World’s Leading Patent Practitioners (2012-2016) and Asia IP Experts (2013).

Our clients rely upon us not only for the uncompromising quality of our professional services, but also for our commitment to providing accessible and responsive client care often in time-critical situations.  Letters & Thoo constantly strives to maintain these high standards by providing client-focused IP solutions to clients of all sizes and from all industry sectors.

As part of our ongoing commitment to maintaining the highest quality of professional standards in the field of IP, our patent attorneys proudly serve on the Council of the Asian Patent Attorneys Association Hong Kong Group (APAA), are recognised as Fellows of the Institute of Patent and Trade Mark Attorneys of Australia (FIPTA), and are active members of the Federation International des Conseils en Propriete Industrielle (FICPI) and the International Trademark Association (INTA).
