How does the USPTO currently classify patent drawings?

The USPTO has changed its approach to classifying patent drawings. According to MPEP 608.02(i), “the Office no longer considers drawings as formal or informal.” This means that the traditional distinction between formal and informal drawings has been eliminated. Instead, the focus is on whether the drawings are sufficient for publication and examination purposes, regardless of their formal classification.
