At KhattarWong and Partners, he specialised in Shipping and Criminal Litigation and other ancillary work. He joined Abraham Low LLC as an Associate and became a Partner/Director in 1997, primarily focusing on Civil and Criminal Litigation and Offshore and Singapore Corporate Secretarial work which broadened his experience in handling tax law enforcement and criminal tax prosecution cases. He was also with IRAS for 12 years.
Notable work include representing the Comptroller of Income Tax in the ITBR tax avoidance case of GBF v Comptroller of Income Tax  SGITBR. This was the first time that the Comptroller of Income Tax had used the anti-avoidance tax provision in Section 33 of the Income Tax Act against an individual to void a tax saving planning structure put up and claim the additional tax assessed from the taxpayer.
Patrick was also involved in numerous tax evasion criminal prosecution cases in IRAS and was involved in representing the Comptroller of Income Tax in cases where foreign taxpayers had taken out judicial review applications to challenge IRAS’ decisions.
