특허 침해 확인만 580건
LG에너지솔루션 "소송 등 강력 대응"

후발 기업 특허 침해 사례 급증
소재, 공정, 전극설계, 팩, BMS 등 특허 침해
김동명 사장 "부당한 침해에 엄중 대응"

24일 LG에너지솔루션에 따르면 현재 LG에너지솔루션이 보유한 특허 중 경쟁사가 침해하거나 침해할 것으로 예상되는 전략특허는 1000여개다. 이중 실제로 침해된 것으로 확인된 특허는 580건에 이른다.

LG에너지솔루션은 IT 기기용 소형 배터리부터 전기차용 중대형 배터리에 이르기까지 이미 상업화돼 시장에 판매되는 경쟁사의 제품에서 자사의 고유 기술을 침해하는 사례가 다수 발견되고 있다고 설명했다.

실제로 유럽 각지에 전기차를 판매하는 A사의 전기차 배터리를 분석한 결과 LG에너지솔루션의 코팅 분리막, 양극재, 전극·셀 구조 등 핵심 소재와 공정에서 특허 침해가 30건 이상 확인됐다. 전 세계 내로라하는 전자기기 제조 업체에 납품되는 B사의 배터리 역시 LG에너지솔루션의 특허를 무단 사용한 것으로, 확인된 특허 침해만 50건 이상이라고 LG에너지솔루션은 전했다.

글로벌 배터리 시장의 빠른 성장으로 배터리 기업 간 경쟁이 격화하면서 무분별한 기술 도용 사례도 급증했다. 이런 가운데 주요 기술 특허를 선점한 LG에너지솔루션과 달리 질적으로 우수한 특허를 확보하기 어려운 후발 기업들은 특허 무단 사용으로 유럽, 중국, 인도, 동남아 등으로 시장 진출을 확대하고 있다.

이에 따라 LG에너지솔루션은 합리적인 라이선스 시장 구축을 주도하기 위해 특허풀(Pool)이나 특허권 매각 등 다양한 방식의 수익화 모델을 활용해 나갈 계획이다.

먼저 현재 시장에서 침해 중인 특허를 중심으로 글로벌 특허풀을 통해 주요 특허를 단계적으로 라이선스해 라이선스 사업과 관리를 효율화할 방침이다.

이를 통해 선도업체는 특허권에 대한 합리적인 로열티를 받아 기술 개발 등에 투자를 확대하고, 후발 기업은 정당한 특허권 사용을 통해 제품의 경쟁력을 높이는 선순환 구조가 만들어질 수 있다.

김동명 LG에너지솔루션 최고경영자(CEO)는 "글로벌 시장에서 공정한 경쟁을 위한 필수 요소는 지식재산권 존중"이라며 "기업의 존속과 산업의 발전을 위해 지식재산권을 보호하고 무분별한 특허 침해에 엄중히 대응해 나갈 것"이라고 말했다.

김 CEO는 이어 "선도업체로서 합리적인 라이선스 시장 구축에 앞장서 특허권에 대한 정당한 대가를 수취하고, 미래 핵심 기술 개발도 보다 적극적으로 추진해 LG에너지솔루션만의 차별화된 고객가치를 지속해서 제공해 나갈 것"이라고 덧붙였다.

LG에너지솔루션은 현재 배터리 제조에 상용화돼 쓰이는 기초 기술인 1세대 기술부터 첨단 3세대 기술까지 현재 등록기준 3만2000건, 출원기준 5만000여건에 이르는 특허를 확보하고 있다.

안전성 강화 분리막의 전극 접착력을 높여 다양한 전극 조립체를 구현할 수 있게 하는 특허 기술이 대표적이다.

LG에너지솔루션이 2018년 세계 최초로 음극에 적용한 코팅 기술인 더블 레이어 코팅(DLD) 기술과 탄소나노튜브(CNT) 선분산 기술 등 핵심 공정 기술을 접목한 전극설계 특허도 다수의 침해 사례가 발생하고 있다.

유기용매를 사용하지 않아 친환경적이고 가격경쟁력을 갖춘 기술로 평가받는 건식 전극, 차세대 원통형 배터리 46-시리즈의 주요 특허, 축적된 데이터로부터 개발한 안전진단·배터리 관리시스템(BMS) 등 미래 배터리 산업을 이끌 차세대 배터리에서도 기술 침범이 우려된다.

이한선 LG에너지솔루션 특허센터장(상무)은 "앞으로 기술 주도권을 지키고 산업의 상생 발전을 도모하기 위해 특허권의 정당한 거래 시스템을 조성하고, 불법적인 침해 사례에는 엄중히 대응해 나갈 것"이라고 밝혔다.
