Abstract

In this research, we aim to analyze the trend of Huawei's PCT patent applications. As a result of analyzing Huawei's PCT patents by dividing temporal spans into three periods - the early 2000s, the late 2000s, and the early 2010s -, the following characteristics have been observed. First, the number of PCT patent applications has conspicuously increased from the early 2000s to the late 2000s and this trend has continued during the early 2010s. Second, in terms of a core technological field, whereas Huawei focused on the development of technologies in the 'H04L: transmission of digital information' sector during the early/late 2000s, it changed this field to the 'H04W: wireless communication networks' sector during the early 2010s. Lastly, in the case of the patent maps, it was found that while general communications technologies, as expressed with such keywords as 'user' and 'network,' were actively developed during the early/late 2000s, mobile phone-related technologies grasped this leading position, as shown with the keywords including 'user equipment,' 'base station,' and 'MME,' during the early 2010s. It was also noticeable that Huawei filed LTE-related patent applications more actively than Apple and Samsung Electronics, which implies that it will presumably pioneer the global market more aggressively than its competitors in the future.

본 연구는 화웨이의 PCT 특허 출원 동향을 분석하는 것을 목적으로 하였다. 화웨이의 PCT 특허를 2000년대 초반, 2000년대 후반, 2010년대 초반으로 나누어 분석한 결과, 다음과 같은 세 가지 특징이 관찰되었다. 첫째, 2000년 초반에서 후반으로 들어서면서 PCT 특허 출원건수가 급격하게 증가했으며, 이 증가 추세는 2010년대 초반에도 이어졌다. 둘째, 집중했던 기술 분야는 2000년대 초/후반에는 'H04L: 디지털 정보전송(transmission of digital information)'이었지만, 2010년대 초반에는 'H04W:무선 통신 네트워크(wireless communication networks)' 로 변화하였다. 마지막으로, 특허맵 분석 결과 2000년대 초/후반에는 '사용자', '네트워크'와 관련된 일반적인 통신 기술이 주를 이루었다면, 2010년에는 '사용자 단말기', '기지국', 'MME'와 같은 이동전화 관련기술이 보다 활발히 개발되었음을 알 수 있었다. 특히 최근에는 화웨이가 4G의 주류 기술인 LTE 관련 특허 출원에 있어 애플, 삼성보다 더 적극적임을 고려할 때, 향후 글로벌 시장에서 더 큰 기술적 영향력을 지닐 것임을 시사한다.
