U.S. patent classification subclass 244/35 is for patents related to "sustaining airfoils".
A sustaining airfoil is generally called a wing, plane, or blade. It has a surface designed to be acted upon by a stream of air passing around it to support the aircraft. The leading edge of the airfoil is upstream, and the trailing edge is downstream. A theoretical chord line connects the leading and trailing edges. "an upper surface when viewed planwise from above the chord line, and a lower surface when viewed planwise from below the chord line."[1]
USPC 244/35 "contains airfoils in which the novelty is in the shape of the individual airfoil, either in cross-section or in plan view."

- USPC 244/35.00 means the same thing as 244/35, and for simplicity on this site we will just change them to say 244/35.
- Historically, a subcategory 35A was created possibly by just one examiner for "compressible flow" (airflow) technologies, and at that time the others in 244/35 were put into a Residual 244/35 category, USPC 244/35R. The distinctions were not maintained and we will map 35A and 35R together into 35 here. Patents listed in categories 244/35R and 244/35A should be treated as being in 244/35 on this page, although we'll keep the suffixes on the original patent pages. For more on this, see the discussion page.
- USPC 244/45 "is devoted to the arrangement of airfoils, with respect to each other or to the body upon which they are mounted, but which contains many incidental disclosures of airfoils of unusual shape."[1]
- Subclasses USPC 244/123.1 through USPC 244/124 are for the construction of airfoils such as internal bracing, etc."[1]
