How much is my patent worth? A practical guide for owners
The five questions that drive patent value — and why a granted patent with no market can be worth less than its filing fees.

A patent is a right to exclude others from using an invention for a limited period. Its value is not the invention itself — it is the economic advantage that exclusion creates. That distinction explains why two patents with equally clever inventions can have very different values.
The five questions that drive value
- Is anyone using, or likely to use, the invention? Value comes from products, processes or licences that generate cash.
- How much of the product's profit is due to the patent? A patented component in a large system may justify only a small share.
- How strong and broad are the claims? Narrow claims that are easy to design around protect little.
- How long does protection last? Legal life is capped at 20 years from filing in most jurisdictions; economic life is often shorter.
- Where is it protected? A patent granted only in India cannot stop manufacturing and sales elsewhere.
Which method will a valuer use?
For most revenue-generating patents, the relief-from-royalty method is the starting point: it estimates the royalty you would otherwise pay to use the technology. Early-stage patents in regulated fields are better suited to risk-adjusted NPV or real-option models, and cost-based methods are mainly used as a cross-check or floor.
What you can do now
Gather your patent documents, any product revenue linked to the invention, and evidence of interest from licensees. Our free indicative calculator gives a non-binding range in under two minutes; a preliminary report gives you a reasoned, multi-method value for negotiations — and a registered valuer can review it if you later need a certified figure.
