The United States Patent and Trademark Office (USPTO) has granted patent US12587038B2 to Canon Kabushiki Kaisha. This patent covers a power transmitting apparatus, a power receiving apparatus, and control methods. The core innovation lies in a system that sets two thresholds for determining the presence of a foreign object during wireless power transmission. These thresholds are dynamically adjusted based on the set transmission power, with a higher threshold for confirming a foreign object and a lower threshold for confirming no foreign object. A range between these thresholds indicates a possibility of a foreign object.

This patent grant is primarily an intellectual property matter and does not impose direct regulatory obligations or compliance deadlines on regulated entities. However, companies involved in wireless power transmission technology, particularly those manufacturing or developing such devices, should be aware of this granted patent. It may impact their freedom to operate or necessitate licensing agreements if their technology infringes upon the patented claims. The filing date for this patent was January 10, 2024, and the grant date is March 24, 2026.
