Lifespans are increasing and many consumers are interested in health issues in these busy modern days, developing functional clothing that can be worn everyday is one of the competitive solutions in the oversaturated clothing market. When developing a new item with a fresh idea, it is important to look into prior art beforehand to avoid unnecessary intellectual property right-related disputes. This study investigates Korean domestic patents and utility models about functional clothing in terms of human body performance and health promotion in order to suggest essential data to relevant developers. We selected 324 patents and utility models and made an analysis according to the year, functions, applied technologies, frequency of claims, target wearers and item types. We found problems in current functional clothing patent application trends and suggested new aspects when developing innovative functional clothing items. Data was limited to Korean domestic patents; however, this study is still meaningful giving references to technology roadmaps and encouraging new intellectual property development.

Recently, the number of patent applications have been increasing rapidly every year as the importance of protecting intellectual property rights becomes more important. Patents must be inventive and have novelty. Especially, the novelty implies that the corresponding invention is not the same as the previous invention. To confirm the novelty, prior art search must be conducted before and after the application. The target of prior art search should include not only Korean patents but also foreign patents. Search of foreign patents should be supported by multilingual search techniques. However, a dictionary-based naive approach shows a limitation because some technical concepts are represented in different terms according to each nation. For example, a Korean term and a Japanese term may not be synonym even though they represent the same technical concept. In this paper, we propose a new method to map semantic similarity between technical terms in Korean patents and Japanese patents. To investigate different representations in each nation for the same technical concept, we identified and analyzed pairs of patents those are mutually connected with priority claim relationship. By performing an experiment with real-world data, we showed that our approach can reveal semantically similar technical terms in other language successfully.

세계적인 자원 확보에 대한 경쟁과 재래에너지의 한계성으로 비재래 에너지가 미래의 에너지원으로 주목받고 있다. 그중에서도, 특히 중질유 및 오일샌드를 경질화하여 부가가치를 높이는 중질유분의 고부가화 공정에 대한 수요가 증가하고 있다. 다양한 형태의 중질 탄화수소로부터 Deasphalted Oil (DAO)를 생산하는 Solvent Deasphalting (SDA) 기술이 기존 정제산업에서 사용되어져 왔고, 비재래 에너지원에서의 사용에도 주목받고 있다. 자원 확보 경쟁에 나선 일부 국가에서는 SDA 기술에 대하여 이미 활발한 연구개발 및 DAO의 상업생산을 시작하고 있다. 본 연구에서는 SDA 기술 개발을 위해 필요한 특허분석을 하였고, SDA특허기술이 출원되기 시작한 1970년대부터 최근까지의 한국, 미국, 일본, 캐나다(캐나다 특허는 1950년도 이후 문헌부터 검색), 유럽, 국제특허를 이용하여, 추출, 회수, 용매 및 기타로 세부기술을 분리한 후, 총 334건을 SDA 기술과 관련된 특허로 추출하여 분석하였다. SDA 기술의 연도별 출원동향을 살펴보면, 대략 10년을 주기로 감소하는 구간이 나타나나 전체적으로는 증가하고 있는 경향을 보이고 있으며, 미국특허가 131건(39%)으로 가장 많으며, 그 다음으로 캐나다특허 83건(25%), 유럽특허 45건(13%), 일본특허 35건(11%)으로 나타났으며, 한국특허는 6건(2%)을 출원하여 가장 낮은 출원건수를 보였다. 다른 나라에 비해 SDA 관련 기술이 취약한 한국은 에너지 자원 기술의 효율적 이용을 위해서 SDA 기술에 대한 연구 개발 및 정부지원이 반드시 필요할 것으로 생각된다.

This study analyzed the registration of patent and utility models by fashion firms in Korea. A total of 2,291 registration cases of IPC A41B-H from the period of 1996 to 2009 were collected by KIPRIS of the Korean Intellectual Property Organization (KIPO). All cases were analyzed by year to review the longitudinal trend and 481 cases of IPC A41B (shirts, underwear, baby linen, and handkerchiefs) and 1088 cases of IPC A41D (outerwear, protective garments, and accessories) were analyzed by content (provided benefit type and developing method), by detailed product items and the characteristics of the applicant. The results of this study were as follows: 1) Registration of IPC 41 increased steeply by the year (especially since 2006) and the patent registrations increased more than those in the utility model. 2) Analyzing the application content of A41B on the basis of benefit showed that 75% were to provide new functions and the rest were for health. In terms of the developing method, 83% of benefit provided by the application were by design development, 11.2% were by material, and the rest was by process, In the cases of IPC A41D, 23.6% were for safety and protection. In terms of the developing method, the process and material development were more frequently adopted than in the cases of A41B. 3) The major product types of A41B were socks, underwear, and infant wear, whereas gloves and parts of clothing were major items in A41D. 4) In terms of the characteristics of the applicant, registration by firms was greater for patents than for utility models and registration by foreigners increased in 2006 due to the complete opening of the retail market. 5) Fifteen universities registered for a total 57 cases and major applications were for IT related clothing or high-tech protective items.
