Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 125 words
A package suitable for microwave cooking and browning of a finished food item prepared from a formable, brownable food precursor, comprising: (a) a microwave susceptive mold comprising at least one cavity of a suitable size and shape for the finished food item, said mold having sufficient microwave activity to generate sufficient heat in a microwave oven to brown a brownable food precursor placed adjacent thereto; (b) a portion of formable, brownable food precursor contained with and conformed to said at least one cavity; and (c) a cover extending over and closing the cavity, said cover being provided with a microwave susceptor layer having sufficient microwave activity to generate sufficient heat in a microwave oven to cook and brown a brownable food precursor placed adjacent thereto.
Claim 2
Dependent Claim 125 words
A package suitable for microwave cooking and browning of a finished food item prepared from a formable, brownable food precursor, comprising: (a) a microwave susceptive mold comprising at least one cavity of a suitable size and shape for the finished food item, said mold having sufficient microwave activity to generate sufficient heat in a microwave oven to brown a brownable food precursor placed adjacent thereto; (b) a portion of formable, brownable food precursor contained with and conformed to said at least one cavity; and (c) a cover extending over and closing the cavity, said cover being provided with a microwave susceptor layer having sufficient microwave activity to generate sufficient heat in a microwave oven to cook and brown a brownable food precursor placed adjacent thereto.
Claim 3
Dependent Claim 34 words
The package of claim 1 wherein the microwave susceptive mold comprises a microwave transparent substrate and a microwave susceptor layer on at least the inside surface of the cavity of the microwave susceptive mold.
Claim 4
Dependent Claim 30 words
The package of claim 2 wherein the microwave susceptor layer comprises a layer of film carrying a microwave susceptor material, said film being secured to the surface of the substrate.
Claim 5
Dependent Claim 22 words
The package of claim 2 wherein the microwave susceptor material carried on the film comprises a substantially continuous thin layer of metal.
Claim 6
Dependent Claim 17 words
The package of claim 2 wherein the microwave susceptor material carried on the film comprises metal flakes.
Claim 7
Dependent Claim 13 words
The package of claim 1 wherein the mold comprises a plurality of cavities.
Claim 8
Dependent Claim 38 words
The package of claim 6 wherein the plurality of cavities vary in shape, the variations, and the distribution of the variations, corresponding to variations and distribution encountered in a customary portion of a naturally occurring finished food item.
Claim 9
Dependent Claim 13 words
The package of claim 1 wherein the food precursor is a potato composition.
Claim 10
Dependent Claim 13 words
The package of claim 1 wherein the cover comprises a substantially planar film.
Claim 11
Dependent Claim 132 words
A process of microwave cooking and browning of a food item prepared from a formable, brownable food precursor, said process comprising: (a) preparing the formable, brownable food precursor; (b) placing the food precursor into a cavity in a mold, said mold being microwave susceptive and having sufficient microwave activity to generate sufficient heat in a microwave oven to cook and brown a brownable food precursor placed adjacent thereto; (c) conforming the food precursor to the contours of the cavity of the mold; (d) providing a cover for the mold, said cover having sufficient microwave activity to generate sufficient heat and brown a brownable food precursor placed adjacent thereto; and (e) cooking the food precursor in a microwave oven for a time sufficient to cook the food precursor and to brown its surface.
Claim 12
Dependent Claim 132 words
A process of microwave cooking and browning of a food item prepared from a formable, brownable food precursor, said process comprising: (a) preparing the formable, brownable food precursor; (b) placing the food precursor into a cavity in a mold, said mold being microwave susceptive and having sufficient microwave activity to generate sufficient heat in a microwave oven to cook and brown a brownable food precursor placed adjacent thereto; (c) conforming the food precursor to the contours of the cavity of the mold; (d) providing a cover for the mold, said cover having sufficient microwave activity to generate sufficient heat and brown a brownable food precursor placed adjacent thereto; and (e) cooking the food precursor in a microwave oven for a time sufficient to cook the food precursor and to brown its surface.
Claim 13
Dependent Claim 163 words
A process of microwave cooking and browning of a food item prepared from a formable, brownable food precursor, said process comprising: (a) preparing the formable, brownable food precursor; (b) placing the food precursor into a cavity in a mold, said mold being microwave susceptive and having sufficient microwave activity to generate sufficient heat in a microwave oven to cook and brown a brownable food precursor placed adjacent thereto; (c) conforming the food precursor to the contours of the cavity of the mold; (d) providing a cover for the mold, said cover having sufficient microwave activity to generate sufficient heat and brown a brownable food precursor placed adjacent thereto; (e) cooking the food precursor in a microwave oven for a time sufficient to cook the food precursor and to brown its surface; and (f) interrupting the cooking step prior to said sufficient time, reconforming said food precursor to the cavity of the mold by pressing, and cooking further to complete said sufficient cooking time.
Claim 14
Dependent Claim 163 words
A process of microwave cooking and browning of a food item prepared from a formable, brownable food precursor, said process comprising: (a) preparing the formable, brownable food precursor; (b) placing the food precursor into a cavity in a mold, said mold being microwave susceptive and having sufficient microwave activity to generate sufficient heat in a microwave oven to cook and brown a brownable food precursor placed adjacent thereto; (c) conforming the food precursor to the contours of the cavity of the mold; (d) providing a cover for the mold, said cover having sufficient microwave activity to generate sufficient heat and brown a brownable food precursor placed adjacent thereto; (e) cooking the food precursor in a microwave oven for a time sufficient to cook the food precursor and to brown its surface; and (f) interrupting the cooking step prior to said sufficient time, reconforming said food precursor to the cavity of the mold by pressing, and cooking further to complete said sufficient cooking time.
