Description

E99Z is a residual classification for inventions and technical subject matter related to fixed constructions that do not fit within the established IPC subclasses of Section E. It serves as a catch-all category for novel or unconventional technologies in civil engineering, building, and construction that lack a more specific classification home. Examiners should exhaust all relevant primary and subordinate classes in Section E before assigning E99Z.
