Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
52 words
An article comprising a layer of semicrystalline polymer having a pattern of metal on at least one surface, the crystalline state of said polymer under said metal layer being quasi-amorphous and that quasi-amorphous state being different from the crystalline state of said polymer in areas which are not covered by said polymer.
Claim 2
Dependent Claim
52 words
An article comprising a layer of semicrystalline polymer having a pattern of metal on at least one surface, the crystalline state of said polymer under said metal layer being quasi-amorphous and that quasi-amorphous state being different from the crystalline state of said polymer in areas which are not covered by said polymer.
Claim 3
Dependent Claim
54 words
An article comprising a layer of semicrystalline polymer having a pattern of metal on at least one surface, the crystalline state of said polymer under said metal being different from the crystalline state of polymer which is not under said metal, the crystalline state of polymer which is not under said metal being quasi-amorphous.
Claim 4
Dependent Claim
54 words
An article comprising a layer of semicrystalline polymer having a pattern of metal on at least one surface, the crystalline state of said polymer under said metal being different from the crystalline state of polymer which is not under said metal, the crystalline state of polymer which is not under said metal being quasi-amorphous.
Claim 5
Dependent Claim
56 words
An article comprising a layer of semicrystalline polymer having a pattern of metal the crystalline state of said polymer being quasi-amorphous either in areas not covered by said metal or under said metal on at least one surface, the crystalline state of said polymer being different under said metal than in areas not covered by metal.
Claim 6
Dependent Claim
56 words
An article comprising a layer of semicrystalline polymer having a pattern of metal the crystalline state of said polymer being quasi-amorphous either in areas not covered by said metal or under said metal on at least one surface, the crystalline state of said polymer being different under said metal than in areas not covered by metal.
