Abstract
Abstract A jigsaw puzzle includes outer straight edge pieces forming a rectangular puzzle perimeter; a number of interior straight edge pieces suggesting an interior rectangle and increasing the proportion of the number of straight edge pieces to the total number of pieces in the puzzle; and a number of joiner pieces, some of the joiner pieces crossing the bounary of the interior polygon, and others of the joiner pieces at positions remote from the boundary.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
83 words
A jigsaw puzzle composed of pieces adapted to interfit in orthogonal columns and rows, said puzzle including: a plurality of outer straight edge pieces defining the perimeter of said puzzle; a plurality of interior traditional pieces with wholly irregular convex and concave curved features; and a plurality of interior straight edge pieces defining an interior polygon within said perimeter to increase the numerical proportion of straight edge pieces to said interior traditional pieces in said puzzle and, thereby, the difficulty of said puzzle.
Claim 2
Dependent Claim
83 words
A jigsaw puzzle composed of pieces adapted to interfit in orthogonal columns and rows, said puzzle including: a plurality of outer straight edge pieces defining the perimeter of said puzzle; a plurality of interior traditional pieces with wholly irregular convex and concave curved features; and a plurality of interior straight edge pieces defining an interior polygon within said perimeter to increase the numerical proportion of straight edge pieces to said interior traditional pieces in said puzzle and, thereby, the difficulty of said puzzle.
Claim 3
Dependent Claim
22 words
A jigsaw puzzle as defined in claim 1 in which said perimeter is a rectangle and said interior polygon is a rectangle.
Claim 4
Dependent Claim
23 words
A jigsaw puzzle as defined in claim 1, said interior straight edge pieces defining a plurality of said interior polygons within said perimeter.
Claim 5
Dependent Claim
21 words
A jigsaw puzzle as defined in claim 3 in which said perimeter is a rectangle and said interior polygons are rectangles.
Claim 6
Dependent Claim
114 words
A jigsaw puzzle composed of pieces adapted to interfit in orthogonal columns and rows, said puzzle including: a plurality of outer edge pieces defining the perimeter of said puzzle; a plurality of interior tranditional pieces with wholly irregular convex and concave curved features; a plurality of interior edge pieces within said perimeter suggesting an interior polygon within said perimeter to increase the numerical proportion of straight edge pieces to said interior traditional pieces in said puzzle and thereby, the difficulty of said puzzle; and a plurality of joiner pieces, some of said joiner pieces crossing the boundary of said interior polygon, and other of said joiner pieces disposed at positions remote from said boundary.
Claim 7
Dependent Claim
114 words
A jigsaw puzzle composed of pieces adapted to interfit in orthogonal columns and rows, said puzzle including: a plurality of outer edge pieces defining the perimeter of said puzzle; a plurality of interior tranditional pieces with wholly irregular convex and concave curved features; a plurality of interior edge pieces within said perimeter suggesting an interior polygon within said perimeter to increase the numerical proportion of straight edge pieces to said interior traditional pieces in said puzzle and thereby, the difficulty of said puzzle; and a plurality of joiner pieces, some of said joiner pieces crossing the boundary of said interior polygon, and other of said joiner pieces disposed at positions remote from said boundary.
Claim 8
Dependent Claim
22 words
A jigsaw puzzle as defined in claim 5 in which said perimeter is a rectangle and said interior polygon is a rectangle.
Claim 9
Dependent Claim
23 words
A jigsaw puzzle as defined in claim 5, said interior straight edge pieces defining a plurality of said interior polygons within said perimeter.
Claim 10
Dependent Claim
21 words
A jigsaw puzzle as defined in claim 7 in which said perimeter is a rectangle and said interior polygons are rectangles.
