1. One original copy of Request for 'Original Deposit'

- Both the Korean and English forms should be filled out.

2. Patent strain to be deposited

(1) Strains of bacteria, actinomyces, yeasts, and fungi that can be freeze-dried – 10 ampoules or two plate culture samples
(2) Animal cell lines, viruses and DNA that cannot be freeze-dried – 20 cryovials and 4 cryovials with host cells (in case of viruses and bacteriophages)
(3) Fertilized eggs – cryo-vial (300 eggs for a mouse)
(4) Micro-algae – two slant culture samples or two 50 mL conical tubes
(5) Seeds – 2500 or more seeds (germination rate of 70% or higher, fully dried seed packets of 250 seeds each)
(6) Plant culture sample – Two or more callus plates

- - In the case where a special culture method or media (sample) is required, please send it in advance to reduce the time required for issuing of the deposit certificate.
- In the case of a virus or phage, please submit the host cell, the protocol, and the images before and after the infection together.
- In the case of a fertilized egg, please fill out the Fertilized Egg Explanation Form.
- In the case of seeds or plant callus, please attach a KCTC Phytosanitary certificate. Plant seeds received from outside Korea may require an import permit from the Department of Agriculture. A NPQS (National Plant Quarantine Service) performs in vitro testing of seeds to control pests and diseases inflicting harm on plants. In many instances, the NPQS decides a permit. Therefore, attachment of phytosanitary certificate from your country will be helpful for the import of seeds.

3. A copy of the payment receipt

- Please refer to the service fee page (for 30-year storage).
* The attorney’s address should be the address on the patent form, and the name should be the name of the patent attorney in charge.
