Software Patent Freedom to Operate: Clearing Code Before You Ship

Shipping software means running it straight into a patent field that grows every year. A software patent freedom to operate analysis answers the only question that matters before launch: of the many thousands of software and AI patents on file, which in-force claims actually read on your product, and what do you do about the ones that do? It is a claim-level infringement exercise, not a patent count — and since 2025 it has a second half most teams miss, because a large share of broad software claims may not survive a challenge to their validity at all.

What a Software FTO Analysis Covers

A software patent freedom to operate analysis maps the features of your product — the algorithms, data pipelines, APIs, user-facing workflows and any machine-learning components — against the specific, granted, in-force patent claims that could block you in the markets where you will actually sell. Freedom to operate (FTO) is not the same as patentability. Patentability asks whether you can get a patent; FTO asks whether someone else’s patent can stop you from shipping.

That distinction matters because an FTO opinion turns on claims, not abstracts or titles. A patent with a frightening title may have narrow claims you never touch; a dull-sounding one may have a broad independent claim that reads straight onto your core loop. The work is reading the claims that matter and charting them against what your code does.

• Feature teardown — decomposing the product into claim-readable elements a patent examiner would recognise.
• In-force, in-market search — granted claims that are still alive in your commercial jurisdictions; expired or abandoned rights cannot block you.
• Claim charting — element-by-element comparison of each candidate claim to your product.
• Disposition — design around, licence, challenge validity, or accept and monitor.

Why Section 101 Reshaped Software FTO

In the United States, software patents live under the shadow of Alice Corp. v. CLS Bank International, 573 U.S. 208 (2014), which set the two-step test for whether a claim is an ineligible abstract idea under 35 U.S.C. § 101. For a decade that test was applied unevenly to software. Two recent Federal Circuit decisions have sharpened it for machine learning specifically.

In Recentive Analytics, Inc. v. Fox Corp., 134 F.4th 1205 (Fed. Cir. 2025), the court held that applying generic machine learning to a new data environment is an abstract idea and ineligible, because “iterative training and dynamic updating are incident to the very nature of machine learning.” In July 2026, Dental Monitoring SAS v. Align Technology, Inc. (No. 2024-2270) extended that reasoning to computer vision, ruling that domain-specific training data alone cannot rescue a claim that lacks a concrete technological improvement.

The practical effect for FTO is large. A meaningful fraction of the broadest software and AI claims — the “machine learning, applied to our data” patents — are now invalidation candidates. That means the fastest, cheapest way to clear a blocker is often to show it cannot survive § 101, rather than redesigning your product or paying for a licence. The flip side, confirmed by the USPTO’s July 2024 subject-matter-eligibility update and its AI Examples 47 to 49, is that claims tied to a specific technological improvement do survive — and those are the ones to take seriously.

The Software and AI Patent Thicket You Are Clearing

The field is dense and getting denser. On Harrity Patent Analytics’ 2026 AI Patent 100 list, built from USPTO data, the hundred largest filers alone were granted 16,832 AI patents in 2025, and the top ten owners held 38% of that output — Samsung, Alphabet, IBM, Amazon, Microsoft and NVIDIA among them. The USPTO’s Artificial Intelligence Patent Dataset finds AI present in roughly 60% of all technology subclasses, so even a focused product touches many owners at once.

Concentration is good news for clearance. When a few large portfolios hold most of the field, owner-first triage — charting the biggest holders before the long tail — retires most of the real risk quickly. A diffuse field of thousands of equal owners would be far harder to clear than a concentrated one.

US vs Europe: Two Different Clearance Tests

Software freedom to operate does not transfer cleanly across borders. US eligibility doctrine under Alice and the EPO’s “further technical effect” approach to computer-implemented inventions are built on different foundations, so a claim too abstract to enforce in a US district court can still block you in Europe, and the reverse is equally true. The EPO’s Patent Index 2024 recorded computer technology as its number-one field, with 16,815 applications, so Europe is no quieter a market to clear.

The takeaway is to draw the clearance picture separately for each market. The same claim can demand a § 101 invalidity strategy in the United States and a genuine design-around in Europe, and assuming one answer covers both is how teams get surprised after a regional launch.

How to Run a Software Patent Freedom to Operate Analysis

A disciplined software FTO analysis follows a repeatable sequence, so the opinion is auditable by the investors or acquirers whose counsel will eventually read it:

1. Decompose the product into claim-readable features, in the vocabulary a patent examiner uses, not marketing language.
2. Scope the search to granted, in-force claims in your real commercial markets — nothing else can block a launch.
3. Triage by owner, charting the largest holders first because that is where a blocking independent claim is most likely to live.
4. Chart each candidate claim element by element against your product, keeping only genuine reads.
5. Run a Section 101 validity screen on every survivor, flagging the Recentive-vulnerable claims that can be challenged rather than licensed.
6. Decide each remaining exposure — design around, licence, challenge, or monitor — and document the basis.

We applied exactly this method in our artificial intelligence freedom to operate case study, where an enterprise-LLM launch was cleared by reducing a 16,832-grant field to a short list of in-force claims and retiring the broadest with a § 101 position. It is the same discipline behind our freedom-to-operate analysis service.

Design Around, License, or Challenge: Choosing a Disposition

The point of a clearance exercise is not a list of scary patents; it is a decision on each one. For every claim that genuinely reads on your product, there are four honest options, and the right one depends on cost, timeline and how central the feature is to your value proposition.

• Design around. Re-engineer the feature so it no longer practises the independent claim. This is often cheapest when the claim is narrow and the feature is not load-bearing — a different data structure, a different order of steps, or a non-infringing equivalent.
• License. Pay for the right to practise the claim. This makes sense when the patent is strong and valid, the owner is willing, and the feature is core enough that a redesign would hurt the product.
• Challenge validity. Where the claim is broad and eligibility-vulnerable — the ‘machine learning, applied to our data’ pattern — a Section 101 position, prior-art invalidity, or an inter partes review can retire the blocker for far less than a licence.
• Accept and monitor. For low-probability reads on patents nearing expiry or held by non-enforcing owners, the documented decision may simply be to watch.

The eligibility screen changes how often each option is chosen. Before 2025, a broad software claim usually forced a design-around or a licence. Today, the same claim may be a candidate to challenge, which is why pairing an infringement read with a validity read on every blocker produces a cheaper, more defensible launch plan than treating the two as separate opinions.

When to Run One

Run the analysis before general availability and before any financing or acquisition where diligence counsel will probe your IP risk — typically eight to twelve weeks out, so there is time to design around or challenge the claims that matter. Running FTO early turns clearance into a launch asset instead of a fire drill after a demand letter lands.
