An investor leans across the table and asks, “So what’s your IP actually worth?” You’ve got a patent or two, a trademark, maybe some trade secrets. You know they matter. But putting a dollar figure on something you can’t hold in your hand feels impossible.
Here’s the good news. There are three established ways to value intellectual property, and once you understand them, that question stops being scary. The same IP can carry very different numbers depending on which method you use, and that’s not a contradiction. It’s the whole point.
IP isn’t legal paperwork sitting in a drawer. It’s a business asset that builds real enterprise value. Intangible assets like patents, brands, and software now make up about 90% of the total value of S&P 500 companies, up from 17% back in 1975. For most modern companies, the IP is the value.
So let’s look at the three approaches: cost, market, and income.
The Cost Approach (Cost Basis)
The cost approach answers a simple question: what did it cost to create this IP, and what would it cost to build it again from scratch?
You add up everything that went into making the asset:
- Research and development
- Engineering and labor hours
- Equipment, testing, and trials
- Legal costs to protect it (filing and prosecuting patents or trademarks)
- A reasonable share of overhead
The total is your cost basis. It’s a grounded, defensible number because it’s built from receipts and time you actually spent, not predictions.
This method works best when the IP is new, you have good cost records, and the asset doesn’t generate measurable revenue yet. That describes most pre-seed and seed-stage startups. If you’re building IP before you have meaningful sales, the cost approach is often the only honest number available, because there’s no earnings history to project from yet.
The limitation is the flip side of its strength. The cost approach ignores future earning potential and market demand. It tells you what you spent, not what the asset can earn. A patent that cost $80,000 to develop might unlock a $5 million product line, and the cost approach won’t see any of that upside.
That’s why the cost approach is usually treated as a floor. It’s the baseline, the least the IP is worth, not the ceiling.
If you want a feel for the real numbers that feed a cost basis, I break down what IP protection actually costs and walk through the full patent cost picture for 2026 in a couple of short videos.
The Market Approach (Market Basis)
The market approach asks a different question: what have people actually paid for comparable IP?
Instead of counting what you spent, you look outward at real deals. You find arm’s-length transactions between unrelated parties, sales or license agreements for similar IP, and use those prices or royalty rates as your benchmark. It’s the same logic a real estate appraiser uses when they price your house off recent sales on your street.
This is where the number often jumps above the cost basis. The market doesn’t care what you spent. It cares what your IP can do and what similar assets command. A brand or a patent that took modest money to create can be worth far more if comparable deals say so.
The market approach works best when there’s an active, transparent market with real comparable deals to point to.
The catch is that genuinely comparable IP deals are hard to find. Most are confidential, and every piece of IP is at least a little unique. For novel or early-stage technology, good comparables may not exist at all. Trade secrets are especially tricky here, since by definition they aren’t publicly traded or disclosed, so there’s nothing to compare them against.
The Income Approach
The income approach is usually the one investors care about most, because it measures the thing they’re buying: future earning power.
Here’s how it works. You estimate the future economic benefit the IP will generate over its useful life, then convert those future dollars into today’s value. That conversion is called discounting, and it just reflects a basic truth: a dollar you’ll earn three years from now is worth less than a dollar in your hand today.
So the income approach takes the cash flow your IP is expected to produce, adjusts it for time and risk, and gives you a present-day number.
This is considered the most credible method for IP that already generates revenue, because it directly measures economic benefit instead of standing in for it. When investors talk about why patents matter to a company’s worth, this is the lens they’re using. (I cover the data on how patents actually raise a startup’s valuation in a companion post, if you want the numbers behind the why.)
The limitation is that the income approach runs on assumptions. Future revenue, how long the IP stays valuable, the right risk rate to apply. Change those inputs and the answer moves. A careful appraiser shows their assumptions so you can pressure-test them.
Relief From Royalty: The Useful Shortcut
There’s a popular hybrid that blends the income and market approaches that’s worth knowing about. It’s called relief from royalty.
It’s critical question is: if you didn’t own this IP, how much would you have to pay to license it from someone else?
Owning the IP “relieves” you of those license payments. The value of the IP is the present value of all the royalties you get to avoid. Mechanically it’s an income-approach calculation applied to a real-world royalty rate, which is why it feels grounded.
Here’s a simple version. Say your product does $2 million in annual sales, and comparable licenses in your space run around 6% of sales. That’s $120,000 a year you’d otherwise pay to license the technology. Add up those avoided payments over the life of the IP, discount them to today, and you have a defensible value.
Royalty rates vary widely by industry. Across sectors they range from under 1% to north of 25% of net sales, with high-tech fields often landing around 5% to 11% and medical device or pharma running higher, roughly 8% to 18%. Many deals settle near 5% to 6%.
You’ll sometimes hear about the “25% rule,” a rough guide that pegs a patent royalty at about a quarter of the licensee’s profit. Treat it as a loose sanity check only. Federal courts have rejected it as a basis for calculating patent damages because it isn’t tied to the actual facts of a deal.
Relief from royalty is widely accepted, audit-friendly, and recognized by tax authorities and financial regulators, which is why it’s common for valuing both patents and brands.
When Each Method Fits Your Stage
The method that fits depends on where your company is.
- Pre-seed and seed: Usually pre-revenue, so the cost approach is your honest floor. You’re building the asset now that the market and income approaches will value later.
- Raising a priced round: Investors lean on the income and market approaches because they’re pricing future upside. This is also when IP due diligence and valuation happen together.
- Licensing a product: Relief from royalty fits naturally, since you’re already thinking in royalty rates.
- Acquisition or exit: Acquired IP gets valued under formal accounting standards, and buyers will run multiple methods to support the price.
FAQ
There’s no single fixed number. A patent’s worth depends on the method and the purpose. The cost approach gives you a floor based on what it took to create. The income and market approaches can land much higher if the patent drives revenue or comparable deals support it. The most likely answer is a range, not a specific point.
Cost basis is what it cost to create and protect the IP. Market basis is what comparable deals and economic value say the IP is actually worth. Cost basis is usually lower and acts as a floor. Market basis is usually higher because it reflects earning power and demand, not just spending.
It depends on your stage and your reason for asking. Pre-revenue startups usually rely on the cost approach. Companies raising money or being acquired lean on the income and market approaches. Licensing deals fit the relief-from-royalty method. Often the strongest answer comes from running more than one and comparing.
It values your IP by the license payments you avoid by owning it. You figure out what you’d pay to license comparable IP, then calculate the present value of all those avoided payments over the asset’s life. It blends real market royalty rates with an income-style calculation, which makes it both grounded and defensible.
You can get a rough sense of the cost basis on your own, since it’s built from your own records. But market and income figures take real comparable data and careful assumptions, and a credible, defensible valuation usually calls for a professional, especially for fundraising, a sale, or a dispute. A back-of-the-envelope number is fine for planning. A number you’ll put in front of an investor or a court is worth doing right.
Because each method answers a different question, and a thorough valuation triangulates. Cost tells you the floor, the market tells you what comparable assets command, and income tells you what the IP can earn. Seeing all three gives you a defensible range rather than a single guess.
Next Steps
If you’re heading into a raise, weighing an offer, or just genuinely curious what your patents and trademarks are worth, the most useful first move is understanding which method fits your situation. That clarity changes how you negotiate.
