How Do I Know What My IP Is Worth?
Your IP is worth the future revenue it protects, discounted to today, which is why acquirers and Big 4 valuers price patents with the income method, usually the royalty-relief model. Cost and market methods give you a floor and a sanity check, but if your patent does not read on a product earning money now, or block one that could, its price at a deal table is close to zero.
Why founders get this wrong
The most common mistake I see is pricing IP by what it cost to create. A founder spends $30,000 filing and prosecuting a patent family, so the balance sheet says $30,000 and the pitch deck says "proprietary technology." Neither number means anything to a buyer. A patent that fences off nothing is worth roughly its scrap value, and a patent that sits on a competitor's roadmap can be worth 100 times its filing cost.
The second version of the same mistake is counting. Twenty filings look impressive in a data room until diligence counsel reads the claims. One enforceable patent that a rival must design around beats 20 defensive filings that protect features nobody would copy. Value in a portfolio concentrates hard: in the portfolios I review, one or two assets usually carry most of the worth and the rest are padding that costs maintenance fees for 20 years.
The three valuation methods, and the one buyers actually use
Every credible IP valuation comes down to one of three approaches. I run all three with clients, in this order, because each one answers a different question.
| Method | What it measures | When it works | Weakness |
|---|---|---|---|
| Cost | What the IP took to develop and file | Setting a floor; early accounting | Weakest. Ignores whether anyone would pay for it |
| Market | Comparable licensing deals and acquisitions | Sectors with visible deal flow | Only as good as your comps, and good comps are rare |
| Income | Discounted cash flow on the revenue the IP protects | Deals. This is what acquirers and Big 4 valuers use | Needs a clean map from claims to revenue |
Cost is where most founders start because the number already exists: legal fees, prosecution costs, engineering time. Treat it as a floor and nothing more. Market comes next: what did comparable patents in your sector license or sell for? The catch is that most licensing deals are confidential, so the comps you can actually see are a thin and biased sample. Use market data to sense-check, never to anchor.
The income method usually runs as a royalty-relief model: if you did not own this patent, what royalty rate would you pay to license it? Apply that rate to the revenue the patent protects, project it over the remaining patent life, and discount it back. With clean data, meaning revenue split by product and a claim chart mapping patents to products, the model takes 2 to 3 weeks. Without clean data it takes as long as it takes you to get clean data.
Four signals you can check in a week
You do not need a valuation firm to get a directional answer. Four questions, one week, no consultants:
- Does the patent read on a product shipping today? Yours or a competitor's. If no product on the market practices the claims, the income method has nothing to price.
- Would a competitor's engineer have to design around it? Ask your own engineers to break it. If they find a cheap detour in an afternoon, so will the competitor.
- Does it block a market a bigger player wants? A patent standing between an acquirer and their roadmap is the single strongest driver of strategic IP value.
- Is the chain of title clean? Signed assignments from every founder, employee, and contractor who touched the invention. A missing contractor assignment can stall a deal on its own.
Score well on 2, 3, and 4 and you have IP worth a formal valuation. Fail on 1 and 3 and the honest answer is that your IP is a story, and stories price at zero in diligence.
The fourth signal deserves its own warning. Chain of title is the item founders skip because it feels like paperwork, and it is the item that bites hardest. Every person who contributed to the invention, including the contractor who left in year one, needs a signed assignment on file. Fixing a broken chain of title mid-deal can cost weeks, and it hands the buyer a discount argument you cannot answer. An afternoon of signature-chasing now is the cheapest valuation work you will ever do.
From my operating seat
I have sat on both sides of this table. Across my three exits, IP was priced by what it protected, never by what it cost. In one deal the buyer's counsel spent more time on assignment documents than on the claims themselves, because a broken chain of title is the cheapest way to knock money off a price. Fixing one mid-deal costs weeks, and it costs leverage, because you are now correcting paperwork while the buyer's lawyers watch the clock.
I run this exact framework with clients now, as the IP and patent strategist alongside the fractional CFO seat, across NYC, London, and Dubai. The same discipline that scaled one of my companies 6x applies here: find the number, tie every asset to it, and cut what does not move it. IP diligence in an acquisition runs 4 to 8 weeks, and the founders who do the one-week check above a year early are the ones who walk through it without a price chip.
How much is the average patent worth?
There is no useful average. Most granted patents never earn a licensing dollar, while a single patent covering a competitor's roadmap can carry an eight-figure price in an acquisition. Value concentrates in one or two assets per portfolio. Price your specific claims against specific revenue, never against a sector average someone quotes you.
What are the standard patent valuation methods?
Three: cost, market, and income. Cost sets a floor and is the weakest. Market prices against comparable licensing deals and lives or dies on comp quality. Income, usually via royalty relief, discounts the cash flow the patent protects and is the method acquirers and Big 4 valuation teams rely on. With clean data the model takes 2 to 3 weeks.
Is my idea worth patenting?
File if a competitor's engineer would have to design around the claim, and the detour would cost real time or performance. Skip it if the invention is easy to keep secret, easy to reinvent, or covers a feature nobody would pay to copy. One enforceable patent on a choke point beats 20 defensive filings, each of which ties up budget for 20 years of maintenance fees.
Get a real number on your IP
This is the exact problem I advise on: royalty-relief valuations, claim-to-revenue mapping, and pre-deal chain-of-title cleanup. If a raise or an exit is anywhere on your 18-month horizon, the one-week check above is the place to start, and I can run the full model from there. See the IP strategy service or book a call.
