"Wherein" clauses limit the scope of the claim. [21] Other forms of purpose language are "whereby" and "thereby" clauses, similar to the "wherein" clauses just described, [22] and statements of intended use in a claim preamble (depending on facts of case, preamble may or may not limit claim scope; in this case it was the "essence of the ...

Not every object falls into a statutory category: for example, electromagnetic waves, [18] and rules for playing games [19] are not patentable (but a new and non-obvious type of dice for playing games may be patentable as a "manufacture").

Thus, according to MPEP, the claims in a patent application may be properly restricted to (i.e. split into) two or more divisional patent applications, if the claims (i.e. claimed inventions) are either independent (MPEP § 802.01, § 806.06, and § 808.01) or distinct (MPEP § 806.05 - § 806.05(j)).
