Company patents
AAC Technologies Pte. Ltd.
AAC Technologies Pte. Ltd. demonstrates a highly concentrated patent strategy, with over half (55.3%) of its portfolio in Loudspeakers & Microphones, a category that saw a remarkable 650.0% YoY growth in 2024, indicating a strong and recent surge in innovation despite a 33.3% decline so far in 2026. Surprisingly, the company appears to be significantly de-emphasizing Electric Motors & Generators, with an 83.3% YoY decline in 2024 and no patents filed so far in 2026, suggesting a shift away from this area.
