Description
B62D covers the construction, design, and component technologies of motor vehicles and trailers. This subclass encompasses chassis design, steering systems, suspension mechanisms, braking systems, body structures, and coupling devices for vehicle attachment. It includes passenger cars, trucks, buses, and towed or semi-trailers, but excludes railway vehicles and rail-guided systems. Related design aspects covered here interact with engine technology (classified separately under B60) and manufacturing processes classified elsewhere.
Filing statistics
IPC subclass B62D recorded 305,422 patent applications worldwide between 2013 and 2023. Annual filings grew from 18,835 in 2013 to 31,035 in 2023 (+65%), peaking at 32,754 applications in 2020. The most active applicants in class B62 are HONDA MOTOR COMPANY (5,614 applications), HONDA MOTOR COMPANY (5,534 applications) and TOYOTA MOTOR CORPORATION (5,128 applications).
