Hello, I am trying to register a medical device patent, but I am not sure where and how to proceed. Since I have only done business in the United States, I am not familiar with domestic patent procedures and registration. I would like to know the procedure for registering a medical device patent and any points to be careful of. If I am not familiar with the Korean medical device patent procedures or regulations, would it be advisable to proceed with the help of an attorney from the beginning?

Hello. I will guide you through the domestic procedures and precautions related to registering a medical device patent.
To register a medical device patent in Korea, you must consider both the Patent Act and the Medical Devices Act, and, unlike an ordinary invention, you must clearly explain the technical features of the medical device and its potential for industrial application.
In particular, if you are already doing business in the United States or elsewhere, whether the device has been disclosed or sold abroad can affect the assessment of novelty in Korea, so you must be very careful.
A medical device patent proceeds through the procedures of a prior art search, the preparation and submission of the application, examination and amendment, the decision to register, and the securing of the patent right.
First, you must review in advance whether it meets the requirements of novelty and inventive step.
If it has already been disclosed or is similar to existing medical technology, registration may be refused.
If there is technical material or use cases disclosed in the United States, you should thoroughly analyze them together with a patent expert before filing.
If you are not familiar with the Korean patent system, and especially in a field where the technology and regulations are complex, such as medical devices, it is advisable to proceed with the help of an attorney specializing in patents or a patent attorney from the early stage.
In addition, because the time required to register a medical device patent averages 26 months after the request for examination, you should proceed with the help of an expert as soon as possible.
Because an incorrect application or an incomplete specification can create risks not only for the medical device patent but also for various business endeavors, I recommend that you take a strategic approach together with a legal expert.
