Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 110 words
A food product comprising a slice or sheet of edible material having an upper surface and a lower surface, said upper surface and said lower surface having substantially parallel corrugations thereon, said corrugations being characterized by a sawtooth function having substantially the same frequency and amplitude, each tooth being asymmetric about its peak, each tooth having first and second sides, said first side being longer than said second side, the corrugations on said upper surface being in phase with the corrugations on said lower surface to yield a relatively thick section adjacent the first side of said tooth and a relatively thin section adjacent the second side of said tooth.
Claim 2
Dependent Claim 110 words
A food product comprising a slice or sheet of edible material having an upper surface and a lower surface, said upper surface and said lower surface having substantially parallel corrugations thereon, said corrugations being characterized by a sawtooth function having substantially the same frequency and amplitude, each tooth being asymmetric about its peak, each tooth having first and second sides, said first side being longer than said second side, the corrugations on said upper surface being in phase with the corrugations on said lower surface to yield a relatively thick section adjacent the first side of said tooth and a relatively thin section adjacent the second side of said tooth.
Claim 3
Dependent Claim 32 words
The food product of claim 1 wherein the sides of said sawtooth function are straight, the first side being from one and one-half to two times the length of said second side.
Claim 4
Dependent Claim 13 words
The food product of claim 1 wherein said sheet or slice comprises potato.
Claim 5
Dependent Claim 90 words
A food product comprising a potato sheet or potato slice having substantially parallel corrugations on opposite surfaces thereon, said corrugations each defined by a periodic waveform having substantially the same amplitude and frequency, said waveform being asymmetric about its peak, each wave having first and second sides, said first side being longer than said second side, the waveforms on said opposite surfaces being in phase to yield a relatively thick section adjacent the first side of said wave and a relatively thin section adjacent the second side of said wave.
Claim 6
Dependent Claim 90 words
A food product comprising a potato sheet or potato slice having substantially parallel corrugations on opposite surfaces thereon, said corrugations each defined by a periodic waveform having substantially the same amplitude and frequency, said waveform being asymmetric about its peak, each wave having first and second sides, said first side being longer than said second side, the waveforms on said opposite surfaces being in phase to yield a relatively thick section adjacent the first side of said wave and a relatively thin section adjacent the second side of said wave.
