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.
Factor Weight
1.Building & Use Cost. Is the invention cheaper or more expensive to build and use than current products?
