Company patents
Iris Ohyama Inc.
Iris Ohyama Inc. exhibits a surprising patent strategy, with a relatively small portfolio of 56 patents showing a focus on manufacturing and building technologies rather than solely consumer goods. While Domestic Cleaning Devices represent a minor 3.6% of its portfolio and have seen a complete cessation of patenting since 2024, the company continues to invest in Pumps (Centrifugal), which grew by 100% in 2024, and HVAC & Air Conditioning, despite a 100% decline in patenting activity so far in 2026 for the latter.
