The procedure for obtaining protection for a utility model is usually simpler than that for seeking patent protection. Substantive and procedural requirements under the applicable laws vary widely among the countries and regions with a utility model system; however, utility models usually differ from patents for invention in the following main ...
[2] That definition is problematic, however, because composite articles can be articles of manufacture—as in the case of a piece of plywood, a concrete sidewalk, a road, a fibreglass bathtub, a (kitchen) countertop, or a flitch beam. [3] Robinson on Patents has defined "composition of matter" in these terms:
