The Korea Patent Attorney (Byeonrisa) Examination is administered through Q-Net (HRD Korea) under the Korean Intellectual Property Office. It comprises a 1st objective multiple-choice examination and a 2nd essay examination. The 1st exam covers industrial property law (Patent Act, Trademark Act, Design Protection Act), introductory Civil Law, and natural science, with a qualifying foreign-language score (e.g., TOEIC 775+) as a prerequisite. Passing the 1st exam generally requires an average near 60 across subjects with no subject below 40. The patent term in Korea is 20 years from filing (Art 88), examination must be requested within 3 years (Art 59), applications are laid open at 18 months (Art 64), and Korea applies an absolute-novelty, first-to-file system. The exam is among the hardest professional qualifications in Korea, with only a small cohort qualifying annually.

1Under Article 29(1) of the Korean Patent Act, which of the following inventions can still be patented despite the listed event occurring before the filing date?
A.An invention publicly known in Korea before filing
B.An invention worked publicly in a foreign country before filing
C.An invention conceived but never disclosed to the public before filing
D.An invention described in a publication distributed abroad before filing
Explanation: Article 29(1) bars patents for inventions that were publicly known, publicly worked, described in a publication, or made available through telecommunication lines before filing. Korea applies an absolute (worldwide) novelty standard, so foreign disclosure counts. A mere private conception that was never made available to the public does not destroy novelty.
2Article 29(2) of the Korean Patent Act denies a patent where the invention could have been easily made by a person with ordinary skill in the art based on prior art. What requirement does this provision address?
A.Industrial applicability
B.Inventive step
C.Unity of invention
D.Enablement of the specification
Explanation: Article 29(2) codifies the inventive step (non-obviousness) requirement: a patent is refused if a person having ordinary skill in the art could easily have made the invention from inventions under Article 29(1). It is assessed separately from novelty under 29(1).
3An inventor disclosed her invention at a public conference in Korea. To preserve patentability under the grace period in Article 30 of the Korean Patent Act, within what period from the disclosure must she file her Korean patent application?
A.6 months
B.30 days
C.18 months
D.12 months
Explanation: Under Article 30 of the Patent Act, a disclosure by a person entitled to a patent is treated as a non-prejudicial disclosure if the application is filed within 12 months of the disclosure. Korea extended this grace period to 12 months consistent with the Korea-US FTA.
4Under the Korean Patent Act, what is the statutory term of a patent right?
A.10 years from the registration date
B.20 years from the filing date of the patent application
C.15 years from the filing date
D.20 years from the registration date
Explanation: Under Article 88 of the Patent Act, a patent right lasts 20 years from the filing date of the patent application (subject to possible term extension for certain pharmaceutical/agrochemical patents). The term runs from filing, not registration.
5Korea operates a first-to-file system. Under Article 36 of the Korean Patent Act, if two applicants independently file applications for the same invention on different days, who is entitled to the patent?
A.The applicant who first conceived the invention
B.The applicant who filed the earlier application
C.The applicant who first reduced the invention to practice
D.Both applicants share the patent right jointly
Explanation: Article 36 establishes the first-to-file rule: where two or more applications claim the same invention filed on different days, only the earliest applicant may obtain a patent. Korea does not use a first-to-invent standard.
6Under Article 42 of the Korean Patent Act, the detailed description of the invention must be written so that:
A.It discloses only the best mode, with no need to enable
B.It claims every conceivable variation of the invention
C.A person with ordinary skill in the art can readily work the invention
D.It is identical to the abstract
Explanation: Article 42(3) requires the detailed description to be clear and detailed enough that a person with ordinary skill in the art can readily work (carry out) the invention. The claims must also be supported by the description and be clear and concise under Article 42(4).
7Under Article 59 of the Korean Patent Act, within what period from the filing date must a request for examination be filed, failing which the application is deemed withdrawn?
A.1 year
B.3 years
C.2 years
D.5 years
Explanation: Under Article 59 of the Patent Act, a request for examination must be filed within 3 years of the filing date. If no request is made within 3 years, the application is deemed withdrawn. (The period was shortened from 5 to 3 years for applications filed on or after March 1, 2017.)
8Under Article 64 of the Korean Patent Act, when is a patent application laid open (published) to the public absent an early publication request?
A.6 months after filing
B.12 months after filing
C.18 months after the filing date or priority date
D.Only after the patent is granted
Explanation: Under Article 64, a patent application is laid open in the official gazette 18 months after the filing date (or the priority date if priority is claimed). Laying-open enables the applicant to later assert a right to compensation under Article 65 against infringing use after warning.
9After receiving a notice of grounds for rejection, an applicant wishes to amend the claims. Under Article 47 of the Korean Patent Act, which limitation applies to such an amendment?
A.Amendments may freely add new matter not in the original specification
B.Amendments may only narrow the abstract
C.Amendments are never permitted after a notice of grounds for rejection
D.Amendments must not go beyond the scope of the matter disclosed in the originally filed specification or drawings
Explanation: Under Article 47, an amendment must stay within the scope of the matter described in the originally filed specification, claims, or drawings; adding new matter is prohibited and is a ground for rejection. Article 47 also restricts the timing of amendments to specified periods during prosecution.
10Under the Korean Patent Act, a divisional application under Article 52 must satisfy which condition?
A.It may claim subject matter never disclosed in the original application
B.It automatically receives a new filing date unrelated to the parent
C.It must be divided from matter included in the originally filed specification or drawings of the parent application
D.It can only be filed after the patent grant
Explanation: Under Article 52, a divisional application must be carved out of two or more inventions included in the originally filed specification or drawings of the parent application, and it is treated as filed on the parent's filing date (benefit of the original filing date). It cannot introduce new matter.
