Appeal 2007-1422
Reexamination Control 90/007,260
Patent 6,093,139
a cutting cylinder cooperating with said product folding
cylinder and having knife assemblies mounted thereon; and
at least one cyclically engageable product seizing element
assigned to at least one of said product folding cylinder and said
cutting cylinder, and being moveable opposite to a sense of rotation of
said product folding cylinder for engaging a next product’s front
portion after a cutting operation.
In order to determine the scope of the claimed subject matter, it is first
necessary to interpret the meaning of several phrases, specifically “product
folding cylinder,” “cooperating with said product folding cylinder,” “knife
assemblies,” “moveable opposite to a sense of rotation,” and “next product’s
front portion.” The meanings of these phrases must be understood in order
to compare the subject matter of Claim 1 to the prior art disclosures of
Sheldon and Stab.
First, we consider the phrases “product folding cylinder” and
“cooperating with said product folding cylinder.” Applicant’s specification
describes a product folding cylinder as a cylinder that performs a folding
function in cooperation with a tucking blade and two fold rollers (Belanger,
col. 3, ll. 24-31). Interpreted in light of the specification then, Applicant’s
product folding cylinder is part of a folding assembly which comprises a
cylinder. Thus, any cylinder which cooperates with another part of a
product folding assembly is a “product folding cylinder.”
