What is required for modifications described in a patent application?
All modifications described in a patent application must be illustrated in the drawings, or the text describing those modifications must be canceled. This requirement is based on Ex parte Peck, 1901 C.D. 136, 96 OG 2409 (Comm’r Pat. 1901). The MPEP section 608.02(f) states:
“All modifications described must be illustrated, or the text canceled.”
However, there are two exceptions to this rule:
- Minor variations
- Well-known and conventional parts
These exceptions do not require illustration. This requirement ensures that the patent application provides a clear and complete disclosure of the invention.
