Abstract
Abstract The method consists of nullifying on a ticket a predetermined number of squares in a first series of squares by the removal of an opaque layer coated thereon and carrying the data to be validated by uncovering, under each square, a respective symbol, and of nullifying all the squares in a second series of squares by the removal of an opaque layer coated thereon and carrying said symbols, except for those squares which carry identical symbols of those uncovered in the first series of squares. If the squares uncovered from the first series identify a date, the presence on a ticket of covered squares in the second series carrying the same symbols as appear in the uncovered squares from the first series certifies that the squares in the second series have been uncovered after uncovering the squares in the first series, thus validating the identified date.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
174 words
A method of validating data entered on a ticket having a substrate with a top surface, a first and second series of symbols reproduced on said top surface of said substrate, an opaque layer covering said first and second series of symbols and contacting said top surface of said substrate, and a third series of symbols reproduced on the top surface of said opaque layer and positioned over said symbols of said first and second series, with said first series of symbols being substantially identical to those symbols of said third series positioned over said second series, said method comprising: (a) removing a predetermined number of symbols of said third series over said first series of symbols along with said opaque layer to uncover a predetermined number of symbols of said first series; and (b) removing said third series of symbols positioned over said second series along with said opaque layer thereover except for those symbols of said third series which are identical to said symbols of said first series uncovered in step (a).
Claim 2
Independent Claim
174 words
A method of validating data entered on a ticket having a substrate with a top surface, a first and second series of symbols reproduced on said top surface of said substrate, an opaque layer covering said first and second series of symbols and contacting said top surface of said substrate, and a third series of symbols reproduced on the top surface of said opaque layer and positioned over said symbols of said first and second series, with said first series of symbols being substantially identical to those symbols of said third series positioned over said second series, said method comprising: (a) removing a predetermined number of symbols of said third series over said first series of symbols along with said opaque layer to uncover a predetermined number of symbols of said first series; and (b) removing said third series of symbols positioned over said second series along with said opaque layer thereover except for those symbols of said third series which are identical to said symbols of said first series uncovered in step (a).
Claim 3
Dependent Claim
94 words
A ticket comprising: (a) a substrate having a top surface; (b) a first and second series of symbols reproduced on said top surface of said substrate; (c) an opaque layer covering said first and second series of symbols and contacting said top suface of said substrate; and (d) a third series of symbols reproduced on the top surface of said opaque layer, and positioned over said symbols of said first and second series, with said first series of symbols being substantially identical to those symbols of said third series positioned over said second series.
Claim 4
Dependent Claim
94 words
A ticket comprising: (a) a substrate having a top surface; (b) a first and second series of symbols reproduced on said top surface of said substrate; (c) an opaque layer covering said first and second series of symbols and contacting said top suface of said substrate; and (d) a third series of symbols reproduced on the top surface of said opaque layer, and positioned over said symbols of said first and second series, with said first series of symbols being substantially identical to those symbols of said third series positioned over said second series.
Claim 5
Dependent Claim
30 words
A ticket according to claim 2, wherein those symbols of said third series positioned over said first series are numerals, arrayed in three groups, to denote day, month, and year.
Claim 6
Dependent Claim
22 words
A ticket according to claim 2 or 3, wherein said opaque layer is a removable paint, removable by either abrasion or solvent.
Claim 7
Dependent Claim
185 words
A ticket comprising: (a) a paper or plastic coated paper substrate having a top surface; (b) a first series of number reproduced on said top surface of said substrate, the values of said first series numbers being no higher than 19; (c) a second series of alphabetic letters; (d) an opaque removable layer covering said first and second series and contacting said top surface of said substrate; and (e) a third series of numbers reproduced on the top surface of said opaque layer and positioned over said first and second series, said third series comprising at least two groups: (i) a first group consisting of third series numbers positioned over said first series, said first group being arranged in three sub groups representing day, month and year, wherein the day sub group numbers are from 1 to 31, the month sub group numbers are from 1 to 12, and the year sub group numbers are numbers representing at least the current year; and (ii) a second group consisting of third series numbers positioned over said second series, said second group being arrayed sequentially from 1-19.
Claim 8
Dependent Claim
185 words
A ticket comprising: (a) a paper or plastic coated paper substrate having a top surface; (b) a first series of number reproduced on said top surface of said substrate, the values of said first series numbers being no higher than 19; (c) a second series of alphabetic letters; (d) an opaque removable layer covering said first and second series and contacting said top surface of said substrate; and (e) a third series of numbers reproduced on the top surface of said opaque layer and positioned over said first and second series, said third series comprising at least two groups: (i) a first group consisting of third series numbers positioned over said first series, said first group being arranged in three sub groups representing day, month and year, wherein the day sub group numbers are from 1 to 31, the month sub group numbers are from 1 to 12, and the year sub group numbers are numbers representing at least the current year; and (ii) a second group consisting of third series numbers positioned over said second series, said second group being arrayed sequentially from 1-19.
