The United States Patent and Trademark Office (USPTO) has granted patent US12582787B2 to NIHON KOHDEN CORPORATION for a "Mask outer frame unit, mask unit, band-including mask unit and mask outer frame." The patent, filed on November 25, 2020, with 9 claims, describes a mask outer frame unit that includes a mask outer frame and a pad designed to contact a patient's face. A key feature is an adjustable portion on the forehead contact part that allows for the angle and position of the pad to be modified.

This patent grant is primarily an intellectual property matter and does not impose new regulatory obligations on medical device manufacturers. However, it establishes exclusive rights for NIHON KOHDEN CORPORATION concerning the patented technology. Other medical device makers should be aware of this patent to avoid potential infringement claims, particularly if developing similar mask designs or components for patient respiratory devices.
