The section Restriction covers the title of the object and signs of the object that are identical to those of the latest known object and is connected to the section Distinction by the phrase distinguishable by or characterized by or equivalent expressions. The section Distinction covers signs that distinguish the object from the latest known object and are combined with signs of the section Restriction to constitute the object of protection claim.
-The protection scope (claim) may include one or more than one points. A multi-point protection scope (claim) may be used to present an object sought to be protected, with the first point (called independent point) and subsequent point(s) used to concretize the independent point (called dependent point(s)); or to present a group of objects sought to be protected, with several independent points, each presenting an object sought to be protected in the group. Such an independent point may have dependent point(s);
-A multi-point protection scope (claim) used to present a group of objects must satisfy the following requirements: Independent points presenting different objects must not invoke other points of the protection scope(claim), unless the invocation helps avoid total repetition of the content of another point; dependent points must immediately follow the independent point on which they are dependent.
Besides the description and protection scope, the patent abstract is also a compelled part in the dossier for patent registration. Accordingly, the patent abstract is used to concisely describe (with no more than 150 words) the nature of the patent. The abstract must disclose principal details of the nature of the technical solution for the informatory purpose and may contain typical drawings or formulas.
