Patent Portfolio Maintenance: Compare patent maintenance and prosecution spending with protected revenue and licensing contribution.
Age 5Explain it to a 5-year-oldStart with a picture
Imagine using Patent Portfolio Maintenance to answer this question: compare patent maintenance and prosecution spending with protected revenue and licensing contribution? Enter Annual patent maintenance and prosecution cost, Annual licensing revenue, Product contribution attributed to protected differentiation, and 2 other inputs; the calculator shows Patent portfolio contribution-to-cost ratio. Try changing one number and watch what happens to Patent portfolio contribution-to-cost ratio. The answer tells you Patent portfolio contribution-to-cost ratio.
Age 15Explain it to a 15-year-oldConnect it to the formula
Strategic blocking value, freedom to operate, jurisdiction and claim quality are not captured by revenue alone. The rule is Patent portfolio return proxy = protected and licensing contribution ÷ portfolio cost. Its input values are Annual patent maintenance and prosecution cost, Annual licensing revenue, Product contribution attributed to protected differentiation, Expected enforcement and defense cost, Active patent families, and the main result is Patent portfolio contribution-to-cost ratio. Try changing one number and watch what happens to Patent portfolio contribution-to-cost ratio.
CollegeExplain it at college levelState the model precisely
This tool models one operating decision from explicitly supplied company assumptions. The implemented relation is Patent portfolio return proxy = protected and licensing contribution ÷ portfolio cost, evaluated from Annual patent maintenance and prosecution cost, Annual licensing revenue, Product contribution attributed to protected differentiation, Expected enforcement and defense cost, Active patent families to produce Patent portfolio contribution-to-cost ratio. Strategic blocking value, freedom to operate, jurisdiction and claim quality are not captured by revenue alone. The model omits unentered taxes, cash timing, legal constraints and market uncertainty. Compare the output with company records and a downside scenario before committing resources.
The decision this tool supports
Compare patent maintenance and prosecution spending with protected revenue and licensing contribution.
Why the business model works
Strategic blocking value, freedom to operate, jurisdiction and claim quality are not captured by revenue alone.
Inputs and operating assumptions
This model uses Annual patent maintenance and prosecution cost, Annual licensing revenue, Product contribution attributed to protected differentiation, Expected enforcement and defense cost, Active patent families. Keep currencies, accounting treatment and time periods consistent with one another.
The formula
Patent portfolio return proxy = protected and licensing contribution ÷ portfolio cost
What the calculator produces
The primary output is Patent portfolio contribution-to-cost ratio; it also exposes Net patent portfolio financial contribution, Annual cost per active patent family. Change one assumption at a time so the comparison remains explainable.
Before using the result in a decision
This compact model cannot capture every tax, accounting, legal, market or operational condition. Compare the output with current company records, cash timing and the downside scenario before committing resources.
