Abstract
Abstract A computer operated method for transforming the appearance of a chemical structure entered into a computer wherein at least one alternate equivalent structure is generated within the computer (or by keyboard entry). A series of parameters applicable to chemical structures are established along with values for such parameters. Following that it is established which of such parameters are present in the first structure and the values thereof are summed to obtain a score. The parameters present in the alternate structures are then established and summed to establish a score for each. The scores are then compared and the highest score is selected and the structure corresponding to the highest score is outputted or printed.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
79 words
A computer operated method for transforming a first chemical structure's appearance, comprising storing within a computer information representative of a series of parameters applicable to chemical structures, and values corresponding to the parameters; entering a first chemical structure into the computer as a first array; establishing which of the stored parameters are present in the first chemical structure and operating on the values present therein to establish a first score; and printing the structure corresponding to the first score.
Claim 2
Dependent Claim
79 words
A computer operated method for transforming a first chemical structure's appearance, comprising storing within a computer information representative of a series of parameters applicable to chemical structures, and values corresponding to the parameters; entering a first chemical structure into the computer as a first array; establishing which of the stored parameters are present in the first chemical structure and operating on the values present therein to establish a first score; and printing the structure corresponding to the first score.
Claim 3
Dependent Claim
17 words
The method of claim 1, wherein the first array is entered into the computer via a keyboard.
Claim 4
Dependent Claim
86 words
The method of claim 1, further comprising generating within the computer at least one alternate array representative of at least one alternate equivalent of the first structure; establishing which of the stored parameters are present in the alternate equivalent and operating on the values present therein to establish a score for the alternate equivalent; comparing the first score and the alternate score and selecting the highest one; and printing the structure corresponding to the thus obtained highest score if it is other than the first structure.
Claim 5
Dependent Claim
59 words
The method of claim 3, wherein establishing which of the parameters are present in the first structure or in an alternate equivalent thereof includes establishing whether any detected ring is symmetrical with a neighboring ring; of regular or irregular shape; oriented similar to a neighboring ring; of an oversized shape; of a secondary shape; or of a tertiary shape.
Claim 6
Dependent Claim
33 words
The method of claim 3, wherein more than one alternate array representative of more than one alternate equivalent of the first structure are generated within the computer; and their corresponding structures are compared.
Claim 7
Dependent Claim
50 words
The method of claim 3, further comprising prior to the score comparing step establishing whether the alternate equivalent includes one or more irregular tertiary or secondary shapes which can be replaced with a more regular shape of the same size and, if so, effecting such replacement in the alternate equivalent.
Claim 8
Dependent Claim
21 words
A method of claim 6, wherein the parameters comprise ring regularity; ring irregularity; ring secondary shape; ring tertiary shape; and symmetry.
Claim 9
Dependent Claim
38 words
The method of claim 7, wherein positive values are established for any regular and irregular rings of 3-8 members present in the structure; and negative values are established for any secondary and tertiary shapes present in the structure.
