B64C AEROPLANES; HELICOPTERS
Description
B64C covers the design, construction, and component technologies of aeroplanes and helicopters, including fixed-wing aircraft structures, fuselage design, wing systems, landing gear, and rotor mechanisms. This subclass encompasses aircraft control systems, stability features, power plant installations, and aerodynamic configurations specific to these aircraft types. Related technologies such as aircraft propulsion, avionics, and auxiliary systems are classified elsewhere within B64, while space vehicles and cosmonautical applications fall under separate divisions.
Filing statistics
CPC subclass B64C recorded 99,021 patent applications worldwide between 2013 and 2023. Annual filings grew from 4,630 in 2013 to 7,634 in 2023 (+65%), peaking at 12,052 applications in 2018. The most active applicants in class B64 are BOEING COMPANY (9,861 applications), AIRBUS OPERATIONS (3,766 applications) and AIRBUS OPERATIONS (3,112 applications).
