Company patents
HAIER SMART HOME CO., LTD.
Haier Smart Home Co. Ltd. demonstrates a clear focus on core consumer appliance technologies, with Refrigerators & Cold Storage (47.3% of portfolio) and Laundry / Dry Cleaning (29.0% of portfolio) dominating its patent strategy. While these core areas saw significant patenting activity in 2024 with YoY growth of +88.2% and +82.1% respectively, the sharp decline in patent filings across nearly all categories so far in 2026, including a -73.0% drop in Refrigerators & Cold Storage and a -60.5% drop in Laundry / Dry Cleaning, suggests a potential shift in patenting priorities or a strategic re-evaluation of R&D output, though 2026 data is partial.
