Patently Apple covered Apple s first patent application for a future smart ring back in 2015 in a report titled "Apple introduces us to the Apple Ring in all its Glory." Apple was granted that patent in April 2020. Then in March 2021 we posted a second smart ring invention in a report titled "Apple Introduces a new kind of Smart Ring System to be used Primarily in Context with AR, VR and MR Applications." Today the US Patent & Trademark Office published a new smart ring patent application from Apple titled "Ring Input Device with Pressure-Sensitive Input."
