Abstract

Understanding technology evolution through periodic landscaping is an important stage of strategic planning in R&D Management. In fields like that of healthcare, where the initial R&D investment is huge and good medical product serve patients better, these activities become crucial. Approximately five percentage of the world population has hearing disabilities. Current hearing aid products meet less than ten percent of the global needs. Patent data and classifications on cochlear implants from 1977-2010, show the landscapes and evolution in the area of such implant. We attempt to highlight emergence and disappearance of patent classes over period of time showing variations in cochlear implant technologies. A network analysis technique is used to explore and capture technology evolution in patent classes showing what emerged or disappeared over time. Dominant classes are identified. The sporadic influence of university research in cochlear implants is also discussed.

利用专利分类探讨技术演变:以人工耳蜗技术专利为例

通过周期性景观来理解技术演变是研发管理战略规划的重要阶段。在医疗保健等领域，初期研发投入巨大，好的医疗产品能更好地为患者服务，这些活动变得至关重要。世界上大约5%的人口有听力障碍。目前的助听器产品只能满足不到10%的全球需求。1977-2010年的人工耳蜗专利数据和分类显示了人工耳蜗领域的格局和演变。我们试图突出专利类别的出现和消失在一段时间内显示在人工耳蜗技术的变化。网络分析技术用于探索和捕获专利类中的技术演变，显示随着时间的推移出现或消失的内容。统治阶级被确定。大学研究对人工耳蜗植入的零星影响也进行了讨论。
