Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 57 words
A printing means comprising a main support member having an outer surface, a saddle member connected to said outer surface, a magnetic member formed of a unitary flat flexible magnetic material secured to said saddle member and a magnetically attractable printing plate member magnetically adhered to said magnetic member by the magnetic force of the magnetic member.
Claim 2
Dependent Claim 57 words
A printing means comprising a main support member having an outer surface, a saddle member connected to said outer surface, a magnetic member formed of a unitary flat flexible magnetic material secured to said saddle member and a magnetically attractable printing plate member magnetically adhered to said magnetic member by the magnetic force of the magnetic member.
Claim 3
Dependent Claim 18 words
