Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 37 words
Seeds coated with an anhydrous coating that consists of a polyester having a melting temperature of 80° C. or less, which has been applied to the seeds as one of a non-aqueous solution and an anhydrous melt.
Claim 2
Dependent Claim 37 words
Seeds coated with an anhydrous coating that consists of a polyester having a melting temperature of 80° C. or less, which has been applied to the seeds as one of a non-aqueous solution and an anhydrous melt.
Claim 3
Dependent Claim 68 words
Seeds coated with an anhydrous coating composition that comprises more than 50% by weight of a polyester having a melting temperature of 80° C. or less and at least one additive selected from the group consisting of plant protection products, beneficial bacteria, and fillers, which composition has been applied to the seeds in one of a non-aqueous solution, and an anhydrous melt, and which polyester is a poly-epsilon-caprolactone.
Claim 4
Dependent Claim 68 words
Seeds coated with an anhydrous coating composition that comprises more than 50% by weight of a polyester having a melting temperature of 80° C. or less and at least one additive selected from the group consisting of plant protection products, beneficial bacteria, and fillers, which composition has been applied to the seeds in one of a non-aqueous solution, and an anhydrous melt, and which polyester is a poly-epsilon-caprolactone.
Claim 5
Dependent Claim 13 words
Coated seeds according to claim 2, wherein the coating composition comprises a fungicide.
Claim 6
Dependent Claim 24 words
Coated seeds according to claim 2, wherein the coating composition comprises bacteria capable of beneficially affecting the germination, formation or growth of the plants.
Claim 7
Dependent Claim 36 words
Coated seeds according to claim 2, wherein the weight of the coating composition equals 0.01 to 100% of the weight of the uncoated seeds, and the coating composition contains from 80 to 100% by weight polyester.
Claim 8
Dependent Claim 24 words
Coated seeds according to claim 2, wherein the weight of the coating composition equals 0.5 to 100 times the weight of the uncoated seeds.
Claim 9
Dependent Claim 23 words
Coated seeds according to claim 2, wherein the weight of the coating composition equals 0.01 to 200% by weight of the uncoated seeds.
Claim 10
Dependent Claim 97 words
Seeds coated with an anhydrous coating composition which is a single layer and consists of at least 80% by weight of a polyester having a melting point of 80° C. or less, which polyester is a poly-epsilon-caprolactone, and up to 20% of at least one additive selected from the group consisting of fillers, plant protection products and beneficial bacteria, which bacteria are capable of beneficially affecting the germination, formation or growth of plants produced from the seeds, and wherein the composition has been applied to the seeds in one of a non-aqueous solution and an anhydrous melt.
Claim 11
Dependent Claim 97 words
Seeds coated with an anhydrous coating composition which is a single layer and consists of at least 80% by weight of a polyester having a melting point of 80° C. or less, which polyester is a poly-epsilon-caprolactone, and up to 20% of at least one additive selected from the group consisting of fillers, plant protection products and beneficial bacteria, which bacteria are capable of beneficially affecting the germination, formation or growth of plants produced from the seeds, and wherein the composition has been applied to the seeds in one of a non-aqueous solution and an anhydrous melt.
