1.2. Types of claim

The Enlarged Board set out in G 2/88 that there are basically two different types of claim, namely a claim to a physical entity (e.g. product, apparatus) and a claim to a physical activity (e.g. method, process, use). These two basic types of claim are sometimes referred to as the two possible "categories" of claim. Within the above two basic types of claim various sub-classes are possible (e.g. a compound, a composition, a machine; or a manufacturing method, a process of producing a compound, a method of testing, etc.). Furthermore, claims including both features relating to physical activities and features relating to physical entities are also possible. There are no rigid lines of demarcation between the various possible forms of claim.
