Special rules of classification within this subclass

F16S is almost never used for classification.

The documents should be classified in the field(s) of application, even if the claims are drafted in a general way.

Almost all documents contain an indication of the field(s) of application in the description. Rarely this is not the case but the name of the applicant, e.g. a well-known automobile or aeronautical constructor, will suggest a field of application to which the document should be circulated.

F16S is used in the very exceptionally case when it is absolutely impossible to infer from the document the field(s) of application and the nature of the object.

Sheets, panels, or other members of similar proportions; Constructions comprising assemblies of such members (built-up gratings F16S 3/00; layered products B32B)
