Frequently Asked Questions

What is the 100X ROI rule?

Craige Thompson’s rule of thumb is that a patent is worth pursuing when the gross profit it protects is at least 100 times the cost of obtaining it. This calculator uses a typical full patent-process cost of $20,000, so the threshold is $2,000,000 in accumulated gross profit.

What costs does the $20,000 figure include?

It reflects the average cost of the full patent process, including prior art research, application preparation, office action responses and monetization consulting. Your actual cost depends on your invention.

Which scenario does the recommendation use?

The recommendation is based on the Most Likely scenario, projected over three years at the growth rate you set.

Is this calculator legal advice?

No. It is a planning tool to help you think about the business case for a patent. For advice on your specific invention, request a free patent needs assessment.
