과거 2015년 이전 게임소송 분쟁들은 게임물을 보호하기 위하여 지식재산권의 보호를 모색하는데 주로 쟁점이 있었다. 게임 내 이미지, 캐릭터 등과 같이 게임 속 창작물은 저작권법에 의한 보호를 받을 수도 있다. 게임 내 로고, 심볼 혹은 표장은 상표권에 의한 보호를 받을 수도 있다. 그러나 게임의 명칭, 게임 규칙, 아이템 기능 등과 같은 그 외의 게임요소들은 단독으로는 저작권이나 상표권 보호를 받기가 어려웠다. 최근, 게임 지적재산권 및 게임 사업 운영 관련 소송 과정에서 부정경쟁방지법 위반의 쟁점이 함께 제기되는 경우가 발생하고 있다. 본고는 가장 최근인 2019년부터 2021년 5월까지 선고된 한국, 미국, 일본 게임 판례 중 부정경쟁방지법 쟁점을 다룬 사례들을 살펴본다. 최근 사례에 등장한 부정경쟁행위 유형은 크게 타인의 성과물을 무단 사용하고 경제적 이익을 해하는 일, 타인의 상품 혹은 그와 유사한 것의 표시를 자신의 영업 에 사용하는 것이다. 관련 분쟁이 독점거래 규제법 위반으로 확장되는 경우도 있다. 부정경쟁방지법에 의한 보호는 전통적인 지식재산법에 의하여 보호하기 어려운 영역도 포섭이 가능하다. 그러나 보호범위가 확장될 수록, 이는 한편으로 게임 개발자들이 새로운 게임을 제작할 경우에 타 게임의 창작물 혹은 게임 회사의 성과물을 침해할 수 있는 위험이 증가함을 의미하기 때문에 주의할 필요가 있다.

In this study, graphene was rapidly grown by chemical vapor deposition using a liquid cell for supplying methanol as a carbon source of graphene. To realize the rapid growth, methanol which is carbon-contained organic solvent was used instead of methane gas, a widely used carbon source for graphene growth. The graphene grown with the growth time as a variable was transferred to a SiO2/ Si substrate with an oxide thickness of 300 nm to confirm whether it was grown with full coverage with an optical microscope. The results confirmed a full coverage in 0.5 min of growth. The Raman spectra also confirmed the G-peak position at 1585.0 cm−1 and an intensity ratio of 2D/G at 2.3 or higher. Concerning electrical transport characteristics, at an induced carrier density of 1 × 1012 cm−2, the hole (μh) and electron (μe) mobilities were 1524 cm2 V−1 s−1 and 1528 cm2 V−1 s−1, respectively. Thus, our study confirmed that high-quality, large-area graphene can be grown within 0.5 min.

Large-scale cultivation of Microcystis aeruginosa in different light conditions was conducted for verifying the cell growth in a greenhouse system. Environmental and chemical parameters of the large-scale culture medium were measured for analyzing the interaction between M. aeruginosa and its symbiotic bacteria. During cultivation, a difference in cell growth pattern was observed between control (natural light) and lightlimited groups (reduction of blue, green, and blue/green light, respectively). Comparing the control group, the light reduced groups showed slow and delayed cell growth through the cultivation period. Also, there is differences in the consuming pattern of total nitrogen and total phosphorus which indicated that the possibility of interaction between M. aeruginosa and symbiotic bacteria.

The carbon anode material for lithium-ion battery was prepared by pyrolysis fuel oil and waste polyethylene terephthalate (PET) additive. The pitch was synthesized as a medium material for carbon anode by heat treatment. The waste PET additive improved the softening point and thermal stability of the pitch. La and Lc of the anode material (heat-treated pitch) increased at higher treatment temperature but decreased by waste PET additive. The electric capacity was evaluated based on effects of defective cavity and developed graphite interlayer, respectively. When the La and Lc of the anode material decreased, the electric capacity by cavity increased based on defective graphite structure. Therefore, the addition of waste PET causes the improved capacity by the cavity. The anode material which has a high efficiency (over 95%) and C-rate (95%, 2 C/0.1 C) was obtained by controlling the process of heat treatment and PET addition. The mechanism of lithium-ion insertion was discussed based on effects of defective cavity and developed graphite interlayer.
