How should figures be labeled in patent drawings?
According to MPEP 507, figures in patent drawings should be labeled as follows:
Each figure must be labeled ‘Fig.’ with a consecutive Arabic numeral (1, 2, etc.) or an Arabic numeral and capital letter in the English alphabet (A, B, etc.). See 37 CFR 1.84(u)(1);
This labeling convention ensures clarity and consistency in referencing figures throughout the patent application and publication. Improper labeling may result in an objection from OPAP and require correction.
