What are the requirements for drawing symbols in patent applications?
Drawing symbols in patent applications must adhere to specific requirements:
- Symbols should be clear and legible.
- The same part of an invention should be designated by the same reference character throughout the application.
- Different parts should not be designated by the same reference character.
- Reference characters not mentioned in the description will not be permitted in the drawings.
MPEP 608.02(b) states: “The drawing must show every feature of the invention specified in the claims.” This includes proper use of symbols and reference characters to clearly illustrate the invention.
For detailed guidelines on drawing symbols, refer to 37 CFR 1.84(p).
