This article is a version of our “Ergonomic Nugget for Chopsticks” design patent as issued by the USPTO, converted to a web-friendly view, for wider dissemination. The issued patent is found as US D934,037 S at USPTO (USD934037S). The specification and accompanying drawings are now in the public domain. And we can now re-upload them to our website without repercussions.
This design patent follows from our utility application on the same topic, Ergonomic chopsticks – US20210059445A1. This design patent covers the top nugget in what we call “model E” ergonomic chopsticks, and it is discussed in 3D training chopstick models. This design patent documents a 3D-printable model that you can freely print yourselves. See for instance, Model E: Ergonomic Marcosticks.
As we stated in our mission page, we want everyone to be able to print these and even sell them without royalty fees. The patent disclosure establishes prior arts that preempt anyone from claiming these inventions, so no one can stop enthusiasts from freely reproducing these chopstick training tools. With the grant from USPTO, we can now enforce our Mark-and-Go license where we simply ask that folks attribute produced training tools to marcosticks.org.
