Hallion, 2003, p. 290:

The Wright's patent problems started with the voluble if well-meaning Octave Chanute. In early 1903 Chanute described the wing-warping principle to the Aéro-Club de France, the key factor alerting French researchers to the importance of roll control. A year later Robert Esnault-Pelterie translated these vague ideas into rudimentary ailerons, which he and other pioneers (including Blériot and Levasseur) fitted to their aircraft before Wilbur Wright flew in Europe. Defendants seeking to circumvent the Wright's patents pointed to Chanute's talk, but also to earlier work by Goupil and Mouillard.

Comment: B64C3/52 seems to cover wing warping as described by the Wrights and others but doesn't include their patents. Reasons could have to do with politics, accidents of classification, or with a non-obvious nuance of the category itself. Notice that B64C3/52 is enclosed by CPC B64C3/44]], "camber"—i.e. a wing bending which might be a permanent feature.
