In Poland, utility models are distinguished as separate subjects of industrial property from inventions. Pursuant to the statutory definition, utility models are new and useful solutions of a technical character concerning the shape, structure or configuration of an object having a solid form. A utility model, like an invention, is considered new if it is not a part of the state of art, which means it has not been made available to the public before the date determining the priority to exclusive right (protection). However, unlike patentable inventions a utility model does not have to meet the grounds of non-obviousness (invention level). Therefore protection can be granted to a utility model despite the fact that for a qualified person it is obvious that the model originates from prior art.
