aggregation of claims.Patents. In a patent application, an excessive number of claims that do

not differ significantly in scope and are essentially duplicative. • Although a patent applicant may

claim an invention and its various features in a reasonable number of ways, each claim must differ

materially  from  the  others.  —  Also termed  multiplicity  of  claims;  undue  multiplicity  of  claims.
