Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
49 words
A copy restrictive medium comprising: a transparent medium incorporating a pattern of visually undetectable microdots that are detectable by opto-electronic means which are capable of deactivating a printing device; an image-bearing medium; and means for laminating said transparent medium to said image-bearing medium to form a copy restrictive medium.
Claim 2
Dependent Claim
49 words
A copy restrictive medium comprising: a transparent medium incorporating a pattern of visually undetectable microdots that are detectable by opto-electronic means which are capable of deactivating a printing device; an image-bearing medium; and means for laminating said transparent medium to said image-bearing medium to form a copy restrictive medium.
Claim 3
Dependent Claim
17 words
The copy restrictive medium according to claim 1, wherein said pattern of microdots forms a unique signature.
Claim 4
Dependent Claim
55 words
A copy restrictive medium comprising: a transparent medium incorporating a pattern of yellow microdots, wherein said microdots are visually undetectable, but can be detected by opto-electronic means which are capable of deactivating a printing device; an image-bearing medium; and means for laminating said transparent medium to said image-bearing medium to form a copy restrictive medium.
Claim 5
Dependent Claim
55 words
A copy restrictive medium comprising: a transparent medium incorporating a pattern of yellow microdots, wherein said microdots are visually undetectable, but can be detected by opto-electronic means which are capable of deactivating a printing device; an image-bearing medium; and means for laminating said transparent medium to said image-bearing medium to form a copy restrictive medium.
Claim 6
Dependent Claim
18 words
The copy restrictive medium according to claim 3, wherein said pattern of yellow microdots forms a unique signature.
