Patent Infringement Analysis: How to Check Before You Launch
Patent infringement analysis is a structured process that compares a product's features against active patent claims to determine whether the product infringes. The analysis has three components: claim mapping (matching product features to patent claims), FTO risk scoring (measuring the probability of infringement), and evidence-of-use documentation (the formal record used in licensing negotiations or litigation). Ipiry's AI runs this analysis against 652,000+ patent records in 60 seconds — free, no credit card required.
What Is Patent Infringement Analysis?
A patent infringement analysis — also called a patent infringement check or freedom-to-operate (FTO) analysis — is the process of comparing your product or business method against the claims of active patents to determine whether you are at legal risk. It is the essential step between identifying patents in your technology space and understanding whether any of those patents represent a real threat to your operations.
The analysis is not a simple keyword search. Patent claims are written in precise legal language, and infringement is determined element-by-element: if every element of a single independent claim is present in your product, infringement likely exists. Missing even one element of every claim means no literal infringement — though doctrine of equivalents can still apply.
Companies perform infringement analysis at four key moments: before product launch (pre-launch FTO), before fundraising (investor due diligence), before acquisition (M&A clearance), and when they receive a patent demand letter (defensive analysis). In each case, the cost of analysis is a fraction of the cost of litigation.
How to Check If Your Product Infringes a Patent
The complete patent infringement search process in four steps. Ipiry's AI completes this in 60 seconds; a law firm takes 2–4 weeks.
Identify Relevant Patents in Your Technology Space
Start with a patent infringement search scoped to your product's CPC (Cooperative Patent Classification) category. Software products fall primarily in G06F, G06N, and H04L. Hardware in H01L, B60W, or A61B. Fintech in G06Q. Ipiry's AI automatically identifies the relevant CPC categories from your product description and surfaces the highest-risk active patents — those with recent forward citations, active owners, and litigation history in your space.

Map Your Product Features to Patent Claims
Claim mapping is the core of every patent infringement analysis. You take each independent claim of a potentially infringed patent and compare it element-by-element to your product's features. Ipiry's AI extracts your product description and maps it against each claim element, flagging specific features that match. The output is a structured patent infringement claim chart — the same format used in litigation.
Key rule: Infringement of an independent claim requires every element to match. If you design around even one element, literal infringement of that claim does not exist.
Score Your FTO (Freedom to Operate) Risk
An FTO patent analysis translates claim mapping results into a risk score. Ipiry's FTO risk score (0–100) weights four factors: claim match strength, patent quality (forward citations), owner activity (litigation history), and remaining patent life. A score above 70 warrants attorney review. Below 30 is generally safe to proceed with standard monitoring.
FTO vs. infringement analysis: Freedom-to-operate analysis is a proactive sweep. A patent infringement check is reactive analysis against a specific patent. Ipiry does both.
Document Evidence of Use
If your FTO risk score is high — or if you are a patent holder who believes a competitor is infringing — the next step is a formal evidence-of-use chart. An evidence-of-use (EoU) chart maps each element of a patent claim to specific documented evidence — screenshots, product documentation, source code references — proving the product performs each claimed element.

How to Avoid Patent Infringement
The most effective strategy for avoiding patent infringement is a pre-launch patent clearance search covering your product's core functionality. Companies that conduct FTO analysis before shipping face 60–80% lower litigation risk than those that wait for a demand letter.
Design Around
Modify your product to eliminate the infringing element. Ipiry's claim chart identifies the specific element to redesign.
Obtain a License
License the technology early. Pre-litigation royalty rates are typically 2–5x lower than post-complaint settlement rates.
Challenge Validity
File an Inter Partes Review (IPR) petition at the USPTO. Approximately 70% of challenged claims are cancelled or amended.
Monitor Continuously
New patents issue weekly. Ipiry's NPE Monitoring alerts you when new patents threaten your product before they reach litigation.

Which Situation Applies to You?
Patent infringement analysis is used differently at each stage of a company's lifecycle.
Pre-Launch Startup
You're about to ship a product and want to confirm you're clear of existing patents before spending on manufacturing, marketing, or fundraising.
- 1.Run Ipiry's free AI FTO scan on your product description
- 2.Review the top 5 highest-risk patents identified
- 3.Commission attorney opinion on any patent scored above 70
- 4.Document your FTO analysis for your investor data room
Fundraising / Due Diligence
Your investors are asking about IP risk in your tech stack, or you're preparing a Series A data room and need to demonstrate clean IP.
- 1.Generate a full FTO risk report across your entire product
- 2.Document your freedom-to-operate position for investors
- 3.Identify any pending risks and your mitigation plan
- 4.Present IP clearance alongside your patent portfolio
IP Holder — Detecting Infringement
You hold patents and believe a competitor's product infringes one or more of your claims. You need to build a licensing case.
- 1.Submit competitor product URL + your patent number
- 2.Ipiry AI generates a preliminary evidence-of-use chart
- 3.Review claim-by-claim mapping against competitor features
- 4.Export EoU chart as starting point for licensing outreach
M&A IP Clearance
You're being acquired, or acquiring a company, and need to clear IP risk across an entire product portfolio before closing.
- 1.Submit full product or technology description
- 2.Receive bulk FTO risk scores across all technology categories
- 3.Identify high-risk patents that could affect deal valuation
- 4.Provide clean IP report to acquiring entity's counsel
Can a Startup Be Sued for Patent Infringement?
Yes — and startups are frequently targeted precisely because they often lack in-house IP counsel. Patent holders can sue any entity that makes, uses, sells, or imports a patented invention, regardless of company size or revenue stage.
Non-practicing entities (NPEs) — sometimes called patent trolls — specifically target Series A and Series B startups. The average NPE settlement exceeds $1M. The average pre-launch FTO analysis from Ipiry costs $0 for the AI scan and $5,000–$25,000 if attorney opinions are needed on high-risk patents.
The highest-risk categories are software (G06F), AI/ML (G06N), fintech (G06Q), and wireless/mobile (H04W). If your product operates in any of these categories, a pre-launch patent infringement check is standard operating procedure for any investor-backed company.
AI Patent Infringement Analysis vs. Law Firm Analysis
Most companies use AI first to triage risk, then commission attorney opinions only on patents that score above 70.
| Factor | Ipiry AI Analysis | Law Firm Opinion |

Frequently Asked Questions
What is patent infringement analysis?
Patent infringement analysis is a structured process that compares a product's features or methods against the claims of an active patent to determine whether the product infringes. The analysis produces a claim chart — a side-by-side comparison of product features and patent claim elements — and an FTO (freedom to operate) risk score. It is used by startups before launch, companies before acquisition, and IP holders building licensing cases.
How do I check if my product infringes a patent?
To check for patent infringement, identify patents in your product's technology category using the USPTO Patent Full-Text Database or a tool like Ipiry. Then map each patent claim element against your product's features — if every element of a single claim matches, infringement is likely. A free AI-powered check takes 60 seconds; a formal attorney opinion takes 2–4 weeks.
What is the difference between patent infringement analysis and freedom to operate (FTO) analysis?
They are the same concept described from different perspectives. Patent infringement analysis asks 'does our product infringe this specific patent?' — usually triggered by a received threat or identified competitor patent. Freedom to operate (FTO) analysis asks 'is our product clear of all relevant patents?' — a proactive sweep before launch. Both involve claim mapping and risk scoring.
How much does a patent infringement analysis cost?
A formal patent infringement opinion from a law firm costs $5,000–$25,000 per patent analyzed, depending on complexity and firm seniority. AI-powered preliminary analysis, such as Ipiry's free tool, costs nothing and delivers an FTO risk score in 60 seconds. Most companies use AI analysis to triage risk, then commission attorney opinions only for high-risk patents.
Can a startup be sued for patent infringement?
Yes. Patent holders can sue any entity that makes, uses, sells, or imports a patented invention — including early-stage startups with no revenue. Non-practicing entities (NPEs), sometimes called patent trolls, specifically target startups because they often lack in-house IP counsel. A pre-launch infringement analysis costs far less than the average NPE settlement, which exceeds $1M.
What is an evidence-of-use chart?
An evidence-of-use (EoU) chart is a formal claim chart that maps each element of a patent claim to specific, documented evidence that a product or process performs that element. EoU charts are used in licensing negotiations to demonstrate infringement to a potential licensee, and in litigation as exhibits. A well-constructed EoU chart significantly improves settlement rates in licensing campaigns.
What does freedom to operate mean?
Freedom to operate (FTO) means a company has determined that its product or process does not infringe any valid, enforceable patent claims in the relevant jurisdiction and technology space. FTO is not absolute — it reflects the best analysis available at a point in time, since new patents are granted continuously. Most companies perform FTO analysis before product launch, before fundraising, and before acquisition.
How long does a patent infringement analysis take?
An AI-powered preliminary analysis takes 60 seconds and covers the primary risk indicators — active claim matches, forward citation overlap, and litigation history in the relevant CPC category. A formal attorney opinion typically takes 2–4 weeks and covers comprehensive claim-by-claim analysis with written legal conclusions. The AI analysis is used to determine which patents warrant attorney review.
What happens if my product infringes a patent?
If your product infringes an active patent, you have four options: obtain a license from the patent holder, modify your product to design around the infringing claims, challenge the patent's validity at the USPTO (IPR petition), or accept litigation risk and continue operations. Most infringement situations resolve through licensing. Early detection gives you more negotiating leverage and lower licensing costs.
Is patent infringement analysis the same as a patent search?
No. A patent search identifies patents that exist in a technology area — it is a discovery step. Patent infringement analysis takes specific identified patents and evaluates whether your product's features match the patent's claims element-by-element. A patent search tells you what patents are out there; infringement analysis tells you whether any of those patents are a legal risk to your specific product.
