The outlook for Malaysia’s patent scene is marred by economic uncertainty. While contentious work is stable, domestic industries have been feeling the pinch and as a result, have tightened their purse strings; the resulting drop in filings has put a damper on short-term prospects for IP agencies and law firms. Silver linings can be found in a recent influx of international applications, which is going some way towards compensating for the domestic decline. Opening its doors to European rights holders, the IP Corporation of Malaysia has rolled out a Patent Prosecution Highway pilot with the European Patent Office, seeking to replicate the success of a similar agreement with Japan; it recently extended the latter programme for a further three years. Despite the United States’ withdrawal, the Trans-Pacific Partnership is going ahead – albeit in a slightly modified form. Retitled as the Comprehensive and Progressive Agreement for Trans-Pacific Partnership, the agreement removes several IP provisions relating to pharmaceutical patents.

Malaysian IP stalwart Advanz Fidelis is an “astute commercial operation” that appeals to both domestic small and medium-sized enterprises and international powerhouses. The team’s unwavering pursuit of quality is paying off; a boom in inbound instructions has driven increasing demand for its services in patent filing, infringement analyses and freedom-to-operate searches, while the contentious arm of the practice is also expanding at a healthy rate.

A dedicated ally for ASEAN rights holders for over 30 years, Mirandah offers cost-effective portfolio management, litigation support and freedom-to-operate search services within the region.

Linda Wang runs the ZICO show with confidence; the patent practice head is widely revered for her incisive counsel and stellar courtroom performances.
