Key Considerations for Employee-Invention Compensation Following Korea’s Introduction of Automatic Succession
1. Key Change Under 2024 Amendment: Automatic Succession of Employee Inventions
A 2024 amendment to the Korean Invention Promotion Act significantly changed the mechanism by which employers succeed to rights in employee inventions.
Under the previous framework, even where an employment agreement or employment regulations provided that the employer would succeed to rights in employee inventions, the employer generally had to separately notify the employee of its decision to succeed to the invention after receiving the employee’s invention report.
Under the amended Act, where an employment agreement or employment regulations provide in advance for the employer’s succession to rights in employee inventions, such rights, in principle, automatically vest in the employer upon completion of the invention. As a result, companies may substantially simplify the individual succession procedures that were previously required.
2. Automatic Succession and Employee-Invention Compensation are Separate Issues
The introduction of automatic succession does not eliminate an employer’s obligation to compensate employee inventors.
The Invention Promotion Act requires “reasonable compensation” for employee inventions. However, it does not require employers to provide separate categories of compensation for succession, patent filing, patent grant, implementation, or other specific events.
Accordingly, where a company’s existing “succession award” was essentially a fixed payment triggered by the completion of the formal succession procedure, the introduction of automatic succession provides an opportunity to reconsider whether such a separate award should be maintained or instead integrated into other components of the company’s inventor compensation program.
The key issue is therefore not whether a particular category of compensation continues to exist, but whether the overall compensation framework provides reasonable compensation under Korean law.
3. Establishing Uniform Compensation Framework
Companies, particularly multinational companies, may wish to replace Korea-specific succession awards with a compensation framework that is more closely aligned with their global inventor award programs.
In considering whether the compensation provided under the program as a whole can be regarded as reasonable, factors such as the overall level of compensation, the economic benefit obtained by the employer from the invention, the inventor’s contribution, and the manner in which the compensation program is established and administered are taken into account.
Accordingly, a company may establish a uniform compensation program centered, for example, on filing and grant awards. What is important is that the company establish objective and consistent compensation standards applicable to employee inventions and administer those standards in a fair and transparent manner.
4. Addressing Exceptional High-Value Inventions on Case-by-Case Basis
In practice, it is extremely difficult to accurately determine the future economic value of every invention at the time of filing.
An invention that appears relatively insignificant when filed may later become a core technology or generate substantial licensing revenue. Conversely, an invention initially regarded as strategically important may ultimately have little or no commercial use.
It is therefore neither practical nor necessarily desirable to design an overly complicated compensation policy intended to anticipate every exceptional circumstance.
A more practical approach is to apply uniform compensation standards as a general rule while maintaining a mechanism for case-by-case review where an invention generates exceptional economic value or an inventor raises a reasonable concern regarding the adequacy of the compensation received.
Employee-invention compensation disputes remain relatively exceptional compared with the overall number of employee inventions handled by companies. It may therefore be inefficient to design or materially modify an entire compensation system solely around the possibility of such unusual cases.
5. Compensation for Former Employees and Changes to Existing Policies
One issue that deserves particular attention when applying a global compensation program in Korea is any requirement that the inventor remain employed at the time an award becomes payable.
For example, if a grant award is available only to inventors who remain employed when the patent is granted, an inventor who completed the invention and contributed to the patent filing may be excluded solely because he or she left the company before the patent was granted.
Employee-invention compensation is different in nature from an ordinary employee welfare benefit or retention incentive. Accordingly, a policy that categorically excludes former employees from compensation solely on the basis of their employment status should be carefully reviewed under Korean law.
Companies should also consider Korean employment law requirements when modifying an existing inventor compensation program. For example, if an existing succession award is eliminated, it may be necessary to consider whether the change constitutes an unfavorable amendment to the applicable employment rules and, if so, whether the relevant procedural requirements have been satisfied.
6. Conclusion
The 2024 amendment to the Korean Invention Promotion Act allows companies to substantially simplify the process for succeeding to rights in employee inventions. Automatic succession, however, concerns the mechanism for acquiring rights and does not eliminate the separate requirement to provide reasonable compensation for employee inventions.
At the same time, companies should not necessarily attempt to design a complicated compensation formula capable of anticipating every exceptional case.
A more practical approach is to establish reasonable and uniform baseline compensation standards, administer them consistently and transparently, and maintain an appropriate mechanism for reviewing exceptional cases individually where concerns regarding compensation arise.
Such an approach can allow companies to take advantage of the simplified succession framework introduced by the amended Act while reducing administrative burdens and continuing to satisfy the fundamental principle of reasonable compensation for employee inventions under Korean law.
