Financial services produce the strongest enforcement record. In BFAM Partners (Hong Kong) Ltd v Mills [2021] HKCFI 2904 the Court of First Instance restrained a departing employee under a six month paid non-compete because the employer particularised its proprietary technology and trading strategies instead of asserting them. Licensed corporations should also align the clause with the Securities and Futures Ordinance (Cap. 571).
Technology and software businesses rely on computer programs being literary works, which brings employee-written code inside section 14. The gaps appear at the edges: contractor commits, code written before joining, and forks of internal tools pushed to public repositories. A disclosure clause covering every external contribution closes most of that exposure.
Life sciences and engineering turn on patents rather than copyright. Standard patents run for up to twenty years and short-term patents for eight, and the Acron decision shows that a broadly defined research role widens the employer's claim to whatever the employee invents. Invention disclosure forms and dated laboratory records decide those disputes.
Group and cross-border structures need naming discipline. A restraint expressed in favour of an employing entity and its subsidiaries has been struck down as reaching beyond the employer's own proprietary interest, so the assignment should identify the group companies that will actually hold the rights, particularly where the employee works across Hong Kong and the Mainland.
