The major patentability requirements are the:
Novelty or inventive step.
Description requirements, that is, the claims are clear and are supported by the specification, and the specification contains enabling disclosure of the claimed invention.
Unity of invention (the application relates to only one invention or a group of inventions that share a single inventive concept improved over the prior art).
Any person can submit information and evidence to KIPO that a patent application fails to meet the substantive patentability requirements, including those set out in Question 1, except for the unity of invention requirement.
Patent infringement actions can be either:
Direct infringement actions, based on a third party's business act of producing, using, transferring, leasing, importing or offering for the sale or lease (including displaying for the sale or lease) of a patented article or an article manufactured by a patented process, or using a patented process.
Indirect infringement actions, based on a third party's business act of producing articles used exclusively to produce the patented article, and so on.
The main defences are:
Nullity of the patent or any claim.
Experimental use exception (that is, using a patented invention for research and experimental purpose, including testing for the purpose of obtaining regulatory approval).
Prior use right. If a person is engaged in the business of using (or preparing to use) a patented invention, without knowing the content of the invention, at the time of filing of the patent application at issue, the person will have a non-exclusive licence for the patent at issue, within the scope of that business.
South Korea has a registration-based (not use) system to protect trade marks. It is therefore advisable to register a trade mark so that it is protected. The Unfair Competition Prevention Act (UCPA) may also protect unregistered marks, but protection under the UCPA is only given to well-known, unregistered marks in Korea.
KIPO registers trade marks. Guidance is available on its website (www.kipo.go.kr).
The opposition grounds are substantially the same as those barring registration (see Question 14).
Disputing the similarity of the marks or goods at issue.
The trade mark owner is not the rightful owner, and the trade mark was obtained in bad faith.
Prior user rights, if the prior user was using its mark before the later mark's filing date without any bad faith intent and the prior user's mark is recognised as a source identifier by South Korean consumers through the prior use.
Copyright can be registered with the Copyright Commission designated by the Minister of Culture, Sports and Tourism. The Copyright Commission's website (www.copyright.or.kr) provides guidance on the application procedure.
Copyright protection starts from the moment a work of authorship is completed, and lasts 50 years after the author's death or publication (or creation) of the work.
Pursuant to the European Union – South Korea Free Trade Agreement, the Copyright Act has been amended to extend the copyright protection term to 70 years, with effect from 2 July 2013.
Copyright infringement occurs when works of authorship are used in various ways (for example, reproduction, public performance, broadcasting, online transmission, exhibition, distribution, or production of derivative works) without consent or beyond the scope of rights granted by contract or beyond statutory exceptions.
See Question 20.
Korea adopts a parallel system for design registrations:
Substantive examination system. A design should have industrial applicability, novelty and creativity.
Non-substantive examination system. A design should have industrial applicability and creativity to some extent.
Goods subject to non-examination are included on a list in the Regulation of the Design Protection Act. Goods on this list are registered after inspection of only the very basic and perfunctory matters. The goods on this list, such as fashion items, are subject to rapidly changing trends. The goods on this list include:
Personal adornment articles.
Bags or portable wallets and so on.
General parts and accessories for clothing and personal adornment articles.
Bedclothes, curtains and so on.
Health and sanitary articles for household purposes.
Articles for congratulations and condolence.
Indoor small organising articles.
Training supplies, painting and calligraphy supplies.
Writing supplies, office supplies.
Office paper, printed matter and so on.
Labels, packaging papers, packaging containers and so on.
Advertising articles, indicating articles and goods displaying articles.
Electronic calculators and so on.
Textiles, boards, strings and so on.
KIPO registers designs. Guidance is available on its website (www.kipo.go.kr).
The opposition or invalidation grounds are substantially the same as those barring registration of a design application under substantive examination, for example:
Lack of industrial applicability.
Lack of novelty.
Lack of creativity.
Similarity to a third party's senior registered design.
Likelihood of confusion with a third party's business.
Possible defences include:
Lack of novelty of the design registration.
The design registration has a narrow scope of protection.
A part of the design is essential to serve a certain function of a product.
The alleged infringing design can be easily created by any person having ordinary skill in the art.
See Question 20.
Unregistered designs can be protected under the UCPA if both the:
Imitation product is made within three years from the date the original product was made.
Product shape is not a commonly used form for such goods.
In addition, an unregistered design may be protected under the Copyright Act if the artistic value of the design can be independently recognised from the combined article.
Grounds for an action include:
Acquiring, using or revealing a trade secret through illegal acquisition.
Acquiring, using or revealing a trade secret knowingly or being grossly negligent in not knowing that the trade secret had been revealed through illegal acquisition.
Using or revealing a trade secret having learned or being grossly negligent in not learning that it was the subject of an illegal acquisition, after the acquisition of the trade secret.
Using or revealing a trade secret in breach of a contractual obligation.
Acquiring, using or revealing a trade secret knowingly or being grossly negligent in not knowing that the trade secret had been revealed in breach of a contractual obligation, or that the trade secret had otherwise been the subject of this revelation.
Using or revealing a trade secret having learned or being grossly negligent in not learning that it was the subject of revelation in breach of a contractual obligation, subsequent to the acquisition of the trade secret.
The main defence is arguing that the alleged trade secret does not meet the requirements to qualify for protection (see Question 44). Other defences include:
No obligation to maintain confidence.
The person acquired the trade secret in good faith.

Korean Intellectual Property Office (KIPO)
