Market Sizing & Opportunity Analysis. Evidence Before the Decision.

A market sizing analysis turns a vague belief that “this could be big” into a defensible number a board, an investor or a licensing counterparty will accept. Done well, it is not a single headline figure but a bottom-up model — total addressable market (TAM), serviceable addressable market (SAM) and serviceable obtainable market (SOM) — built from sources you can cite, with the intellectual property position that protects the opportunity made explicit. For an IP-rich company, the question is never just “how large is the market?” but “how much of it can our patents actually fence off?”

What a Market Sizing Analysis Actually Answers

Every credible market sizing analysis resolves the same three questions in order, and keeps them separate:

• TAM (total addressable market) — the entire annual revenue a product category could generate if every possible buyer bought it. This is the ceiling, not the plan.
• SAM (serviceable addressable market) — the slice of TAM your business model, geography, channel and — critically — your IP rights can actually reach.
• SOM (serviceable obtainable market) — the share of SAM you can realistically win over a defined horizon given competition, capacity and go-to-market.

Confusing the three is the most common way a market model loses credibility in a diligence room. A TAM quoted as if it were revenue reads as hype; a SOM built without a defensible SAM reads as a guess. Our job is to make each layer traceable to an assumption an outsider can check.

The discipline matters most when money changes hands. A licensing negotiation, a Series B raise or an acquisition memo all hinge on whether the buyer believes your SAM is real — and whether the IP moat that defines it will hold.

Top-Down vs Bottom-Up: Why We Build From the Unit Up

There are two ways to size a market, and they are not equally persuasive. A top-down market sizing analysis starts from a published industry figure and shaves it with percentages: “the global market is $600 billion, we will take 2%.” It is fast, and it is almost always wrong, because the 2% is asserted rather than derived.

A bottom-up analysis starts from the unit — a defined buyer, a price, a purchase frequency — and multiplies up to a total. It forces every assumption into the open: how many buyers exist, what they pay, how often they repurchase, and what share your offering can hold. When a number is built this way, a skeptical reader can attack any single input without collapsing the whole model, which is exactly why investors trust it more.

We default to bottom-up, then use top-down published figures only as a sanity ceiling. If the two methods disagree by an order of magnitude, that gap is itself a finding worth explaining before anyone acts on the model.

Tying the Market to the IP That Protects It

This is where an IP-aware market sizing analysis differs from a generic consulting deck. A market you cannot defend is a market you will share with every fast follower, and shared markets compress margins toward zero. The addressable question for a patent owner is therefore narrower and more valuable: how much of the SAM sits behind claims you own or can license?

The economic weight of that question is not theoretical. The USPTO’s 2024 study found that 128 IP-intensive industries accounted for roughly $11.4 trillion of U.S. GDP — about 44% of the total — and supported 49.6 million direct jobs. In the EU, the EPO and EUIPO put IPR-intensive industries at 47.9% of GDP and one in three jobs. Markets protected by IP are not a niche; they are the majority of the advanced economy.

We map each SAM segment to the patents, applications and licences that govern it, then flag the segments where protection is thin. Those thin segments are where a competitor can enter cheaply — so we discount them, rather than let a headline TAM paper over the risk.

A Six-Step Market Sizing Analysis Method

We run every engagement through the same six steps so the model is auditable end to end:

1. Define the unit of demand. One buyer, one purchase, one price — stated precisely enough that two analysts would count it the same way.
2. Count the population bottom-up. Build the buyer count from primary registries, filings and trade data, not from a rounded industry headline.
3. Price the unit and its frequency. Anchor price to observable transactions, and separate one-off from recurring revenue.
4. Layer in the IP position. Map each segment to the patents or licences that protect it; discount segments your rights do not reach.
5. Derive TAM, SAM and SOM. Carry the assumptions forward transparently so each layer is a function of the last, not a fresh guess.
6. Stress-test and cite. Cross-check against a top-down ceiling, log every source, and record the assumptions most likely to move the answer.

The output is not a slide with one number on it. It is a model a reader can open, disagree with on a single line, and still trust on the rest — which is the only kind of market sizing analysis that survives contact with due diligence.

What the Data Says About IP-Driven Markets

Sizing an innovation market without looking at filing data leaves the fastest-moving signal on the table. Patent filings are a forward indicator of where companies expect demand, and the 2024 numbers are unambiguous about direction.

WIPO recorded 3.7 million patent applications filed worldwide in 2024, up 4.9% — the fastest year-on-year growth since 2018. Computer technology was the single largest field at 13.2% of global filings and the only top-ten field to grow at double digits over the past decade; electrical machinery (7.2%) and digital communication (5.8%) followed. Asia accounted for 70.1% of filings, with China alone receiving 49.1% of the world total.

Those field-level shares are a map of where addressable markets are expanding fastest. When a client’s SAM sits in a field that is compounding at double digits in filings, we treat that as corroborating evidence of demand; when the filings are flat but the pitch claims explosive growth, that contradiction goes at the top of the report.

Common Market Sizing Mistakes That Sink a Model

Most market models fail for a handful of repeatable reasons. We audit against each before a number leaves the building:

• Quoting TAM as if it were revenue. The ceiling is not the forecast, and treating it as one destroys credibility instantly.
• Double-counting buyers across segments. Overlapping definitions inflate the population and the total.
• Ignoring the IP moat. A SAM that any competitor can copy is not really serviceable, and pretending otherwise overstates defensible revenue.
• Anchoring to a stale market report. A three-year-old figure in a field growing at double digits is already wrong.
• Hiding the assumptions. A model no one can inspect is a model no one will trust when it matters.

A market sizing analysis is only as strong as its weakest cited assumption. We would rather ship a smaller, defensible SAM than a larger one that unravels under a single sharp question in a diligence meeting.

Sizing a High-Growth Field: The Semiconductor Example

A worked example shows why the IP overlay matters. The global semiconductor market was worth roughly $627 billion in 2024 and is widely forecast to approach $1 trillion by 2030, propelled by AI accelerators and memory. That headline is the TAM ceiling — but no single chip designer serves all of it, and the CHIPS Act’s $39 billion in incentives is reshaping who can serve which slice.

The defensible layer is smaller and more interesting. The semiconductor intellectual-property market — the licensable IP blocks and cores that go into chips — was about $7.5 billion in 2024 and is projected to reach roughly $11.2 billion by 2029 at an 8.5% compound rate, with the royalty segment the fastest-growing part. That royalty pool is the SAM a patent owner in this field can actually address, because it is revenue gated behind IP rights rather than raw silicon volume.

So the same field yields a $600-billion TAM and an $8-billion IP-royalty SAM — a hundred-fold difference that only appears once you separate the market you can see from the market you can defend. Our semiconductor engagements build both numbers side by side so a client never mistakes the ceiling for the opportunity.

From Market Size to Licensing Value

A sized market becomes a financial figure through the royalty it can command. In standards-heavy sectors, essential-patent royalties commonly fall in the low single digits — often quoted in the 1% to 5% of product revenue range, depending on how essential the claims are and how the stack of contributors shares the burden. Applied to a serviceable market, that rate turns a demand estimate into an addressable licensing revenue.

This is the bridge from opportunity analysis to valuation. Once the serviceable market is bounded and a defensible royalty is benchmarked against comparable licences, the same model feeds directly into an IP valuation or a damages theory. We build the two together so the market number and the money number never drift apart — a sized market that cannot be monetised is an interesting fact, not an asset.

The connection runs both ways. A licensing counterparty who disputes your royalty will attack the market behind it first, so a model that has already stress-tested its own SAM is far harder to negotiate down.

What You Receive

Every engagement ships with:

• A bottom-up TAM / SAM / SOM model you can open and interrogate line by line
• Segment-level growth rates anchored to filing and trade data
• A source-cited assumptions log — every input traceable to a primary source
• An IP-overlay that flags which segments your patents actually protect
• An opportunity ranking of segments by defensible revenue, not raw size
