Do patent drawings have to be put right?

yes. Patent drawings must be straightened. When the horizontal dimension of the parts is obviously larger than the vertical dimension and must be arranged horizontally, the top of the drawings should be placed on the left side of the drawings. When there are more than two drawings on a page, and one of them has been horizontally arranged, the other drawings on the page should also be horizontally arranged.
