How should broken lines be used in international design application reproductions?
How should broken lines be used in international design application reproductions?
Broken lines in international design application reproductions serve specific purposes and must be used correctly. The MPEP 2920.04(b) states:
“Broken lines may be used to show visible environmental structure, but may not be used to show hidden planes and surfaces that cannot be seen through opaque materials.”
Key points about using broken lines:
- Use broken lines to depict visible environmental structure
- Do not use broken lines for hidden planes or surfaces
- Broken lines cannot represent surfaces obscured by opaque materials
- A broken line disclosure must be described in the specification
The proper use of broken lines helps distinguish between claimed and unclaimed subject matter, providing clarity in the design patent application.
