Each factor should objectively be assigned a commercial advantage or disadvantage score on a scale of -100 to +100 (-100 being a significant disadvantage and +100 being a significant advantage). If the factor is irrelevant to your invention, a value of 0 should be assigned. You should not base any decisions solely upon use of this form. Remember, this form is only effective if you are objective in evaluating your invention (hint: if you don't have any negative factors you probably weren't objective!).

EXAMPLE: If the "cost" to build and use your invention is much more expensive than conventional products you should give that factor a score between -50 to -100. If the "weight" of your invention is much lighter than conventional products you should give that factor a score between +50 to +100. If the overall size of your invention is not important to consumers you should give that factor a score of 0 as not applicable. You continue this process with all of the factors and then add the Total Score.

You should print out this form after filling it out for review later.
