The Korean Patent Act includes several provisions which make the filing requirements more flexible. You can obtain an early filing date by
- filing a provisional specification, followed by a complete specification within the next twelve months
- filing an application in any form (e.g. research notes, thesis, etc.), followed by an application in the proper form, and fulfilling the formal requirements, within 14 months from the earliest priority date (permitted since 1 January 2015)
- filing an application in English, followed by an application in Korean within 14 months from the earliest priority date (permitted since 1 January 2015).
