Patentability vs. freedom to operate
Can you patent it—and can you bring it to market?
A patentability review asks whether your invention may qualify for patent protection. A freedom-to-operate review asks whether defined commercial activities may infringe another party’s patent rights. A positive answer to the first question does not resolve the second.
Two reviews, two different decisions.
| Question | Patentability | Freedom to operate (FTO) |
|---|---|---|
| Main focus | The invention you may claim in an application. | The product, process, or activity you plan to commercialize. |
| Material reviewed | Relevant prior art, including patent documents and other public disclosures, together with patentability requirements. | Potentially relevant patent claims, their legal status, and the proposed activity in identified countries. |
| Business decision | Whether and how to pursue a filing. | How to assess patent risk before a defined commercial step. |
| Key limitation | Does not establish permission to sell a product. | Does not establish that your own invention is patentable or eliminate all legal risk. |
A U.S. utility application must satisfy requirements including eligible subject matter, utility, novelty, nonobviousness, and adequate disclosure. Searching alone does not decide all of these issues. See the USPTO’s examination guidance.
Your patent is not a permit to sell.
A U.S. patent gives its owner a right to exclude others from certain activities. It does not grant affirmative permission to practice the invention. A patentable improvement may still use technology covered by someone else’s unexpired patent. The USPTO explains this distinction and the limits of its examination.
A hypothetical example: a smarter irrigation controller.
A small company develops a new sensor-calibration method for an irrigation controller. A patentability review could assess whether that method differs sufficiently from earlier disclosures and meets the other requirements for a filing.
The finished controller also includes a valve-control arrangement. A separate FTO review might identify an unexpired U.S. patent whose claims need comparison with that arrangement. A potential patent on the calibration method would not settle that issue.
The two reviews could therefore lead to different next steps: developing a filing strategy for the improvement, while evaluating the relevant claims and possible product changes or licensing options. This invented example is not a client result or a conclusion about any actual patent.
Define the product, countries, and timing.
A useful FTO discussion starts with what you plan to do, where, and when. Identify the product version, important components, operating steps, and planned manufacturing, sales, use, or importation. Patent rights are territorial; a review limited to the United States is not worldwide clearance. International teams may need appropriately qualified counsel in other markets.
A patent’s title, abstract, or drawings alone do not settle infringement. Counsel must consider the relevant claims and legal status in relation to the proposed activity. Related applications and patents may also matter. WIPO’s guide to searching and analyzing patent rights explains this scope-based approach.
Discuss the search coverage, written analysis, assumptions, exclusions, and whether later updates are included. Changes to a product, market, or patent record can change the question being assessed.
Questions businesses often ask.
If our search found nothing similar, are we clear to launch?
No. A patentability search has a different purpose and scope from an FTO analysis. Even a carefully scoped FTO review cannot guarantee that every relevant right has been identified or that no dispute will arise. WIPO describes FTO analysis as a way to assess and reduce risk.
Does an expired patent stop us from using the technology?
An expired patent is different from an enforceable unexpired patent, but confirm the status and check for other rights covering the planned activity. The disclosed technology may still be relevant prior art when assessing your own invention. Finding an old document is neither automatic clearance nor an automatic reason to abandon a new filing.
Can we ignore a published application that has not issued?
Not automatically. A published pending application may warrant monitoring because its claims and status can change. Ask counsel how it affects the review and whether an update before launch would be appropriate.
Does a patent FTO review cover every risk in a launch?
No. The agreed scope matters. Trademarks, copyright, trade secrets, contracts, regulatory approvals, and other issues may need separate attention. A patent review should not be presented as approval of every aspect of the business.
What affects the cost of an FTO review?
The cost of a freedom-to-operate review depends on the work needed to assess a defined product or activity. A useful estimate starts with what you plan to make, use, sell, or import, where, and when.
- Product scope: The technical complexity, features, and product versions to be reviewed, and the detail available about how they work.
- Countries: The markets and activities covered. Additional jurisdictions may require local counsel, translations, and separate fees.
- Search and analysis: The search coverage and the number and complexity of relevant claims, related patent families, and legal-status questions.
- Deliverables and timing: The depth of written analysis, any design alternatives to assess, the deadline, and whether later updates are included.
A review of one identified patent, a broader search, and a written FTO opinion involve different work. Reviewing a single patent does not identify every other right that could matter. A search report identifies potentially relevant documents; it does not by itself provide a legal opinion on the proposed activity.
Before engagement, agree on the product version, countries, search coverage, written deliverables, assumptions, exclusions, and fee basis. Specify whether changes to the product or patent record require separately authorized updates. A limited initial review should not be treated as comprehensive clearance.
See our patent costs and payment options for how defined scopes and possible installment arrangements are discussed. Availability and terms depend on the engagement; outside search, translation, and foreign-counsel expenses should be identified separately.
Prepare the facts before commissioning a review.
- The decision ahead: filing, prototyping, manufacturing, importing, or launching.
- The current product version and the features or processes that matter.
- Target countries, the supply chain, and expected timing.
- Known patent numbers, competing approaches, licenses, and earlier search reports.
- Design alternatives, budget, and any letters or identified disputes requiring prompt attention.
A limited review of an identified patent, a broader search, and a written FTO opinion are different assignments. Agree on the appropriate scope with counsel. Our patent search and assessment page explains the patentability process; our small-business patent counsel page connects reviews with continuing product and portfolio decisions.
Start with the decision you need to make.
Parti & Oliveira PLLC can discuss the patent work appropriate to your invention, product, and intended markets. Describe the general technology, country, planned activity, and any known deadline in a nonconfidential inquiry. The engagement must define the work accepted; filing representation does not automatically include an FTO opinion.
Review patent costs and possible payment arrangements. Wait to send confidential designs, reports, or correspondence until the firm confirms how to proceed. Contacting the firm does not establish representation.
