About Patent Law in Cheongju-si, South Korea

Patent law in Cheongju-si is governed by national South Korean intellectual property law, administered by the Korean Intellectual Property Office - KIPO. Patents grant the right to exclude others from making, using, selling, or importing a claimed invention for a limited term, subject to compliance with statutory requirements. Although the law is national, Cheongju-si residents use local services such as patent attorneys based in Cheongju, neighboring Daejeon, and larger hubs like Seoul for filing, prosecution, and litigation. For disputes and appeals, specialized patent courts and administrative procedures based in the region and nationwide handle enforcement and invalidation matters.

Frequently Asked Questions

What is a patent and what does it protect?

A patent is a legal right granted for a new and inventive technical solution to a problem. It protects the claimed invention by giving the patent owner the right to exclude others from making, using, selling, or importing the invention within South Korea for the patent term.

How long does patent protection last in South Korea?

Patent protection is generally valid for 20 years from the filing date for invention patents, subject to payment of maintenance fees and any statutory adjustments. Different rules can apply for utility models or other forms of protection.

Can foreigners file patents in Cheongju-si or South Korea?

Yes. Foreign applicants can file patent applications in South Korea. Because KIPO proceedings are conducted in Korean, foreign applicants typically engage a Korean patent attorney to represent them in prosecution and administrative matters if they do not have a local representative.

Do I need a local patent attorney to file in Korea?

While an initial filing may be prepared abroad, practical prosecution before KIPO normally requires a Korean-registered patent attorney for responses, translations, and formal representation. Working with a registered patent attorney is recommended to avoid procedural pitfalls.

How do I check if my invention is already known?

Start with a prior art search using patent databases and technical literature. The Korean patent search service KIPRIS and international patent databases are useful. A patent attorney can conduct a professional search and interpret results to assess novelty and inventive step.

How long does it take to get a patent granted?

The timeline varies. After filing, a request for substantive examination must be made within the statutory period. From the examination request, prosecution and examination can take several months to a few years depending on complexity, field of technology, and whether amendments are needed.

What are common costs involved in obtaining a patent?

Cost components include filing fees, search and examination fees payable to KIPO, translation costs if filing from abroad, and professional fees for patent attorneys. Costs vary by complexity and whether international filings are pursued, so get a fee estimate before starting.

What should I do if someone in South Korea is infringing my patent?

Document the infringement, consult a patent attorney promptly, and consider sending a cease-and-desist letter or seeking provisional measures if appropriate. Remedies can include injunctions, damages, and settlement negotiations. Timely evidence collection is important for enforcement.

Can I file internationally from South Korea?

Yes. South Korean applicants can use the Patent Cooperation Treaty system to seek protection in multiple countries via an international application. You can also claim Paris Convention priority from an initial Korean filing when filing abroad within the priority period.

What happens if someone challenges my patent after it is granted?

Third parties can request invalidation or bring administrative and judicial proceedings challenging validity. Patent owners must prepare to defend the patent with technical and legal arguments, and may amend claims in some proceedings. A patent attorney can advise on strategy and representation.
