design patents

Design patents protect the ornamental design of an article of manufacture, covering its shape, pattern, or surface ornamentation rather than functional aspects.

The tag covers legal developments, enforcement strategies, and the impact of design patents on mass-market products, with a focus on U.S. court cases and procedural tools like Schedule A filings.
