Abstract: Understanding technology evolution through periodic landscaping is an important stage of strategic planning in R&D Management. In fields like healthcare, where initial R&D investments are huge and good medical products serve patients better, activities of periodic landscaping become crucial for planning. Approximately 5% of the world’s population experience hearing disabilities. Current hearing aid products meet less than 10% of the global needs. Patent data and classifications on cochlear implants from 1977 to 2010 show the technology evolution in the area of such implants. We attempt to highlight the emergence and disappearance of patent classes over a period, indicating changes in the growth of cochlear implant technologies. Using the network analysis technique, we explore and capture the technology evolution in patent classes by showing what emerged or disappeared over time. Dominant classes are identified. The sporadic influence of university research in cochlear implants is also discussed.
