Patent Design-Around Strategy

What to Do When a Patent Claim Affects Your Product

You are developing a product.

The design is working. Your team is making progress. You may already be thinking about testing, manufacturing, investors, or launch.

Then you find a patent that appears close to part of your product.

The first question is usually:

“Can we still move forward?”

Finding a potentially relevant patent does not always mean the project has to stop.

A better question may be:

“What does the patent claim actually require, and can we achieve our goal in a different technical way?”

That is where a patent design-around strategy can help.

A patent design-around strategy involves reviewing the requirements of a patent claim and exploring whether the same product goal can be achieved through a meaningfully different technical solution. This may involve changing a component, connection, process, arrangement, or overall technical approach. The redesigned product should then be reviewed against the relevant claims and other potentially relevant patent rights in the target market before important business decisions are made. A design-around can address a specific claim concern, but it does not by itself establish non-infringement or Freedom to Operate.

What Is a Patent Design-Around Strategy?

A patent design-around strategy starts with understanding what a patent claim requires and then exploring another practical technical approach.

The goal is not simply to make the product look different. It is to create a technical difference that matters.

For example, imagine a patent claim requires:

A → B → C → D

and your product uses the same combination.

Your engineering team may explore whether the product goal can instead be achieved using:

A → B → C → E

The important question is whether that alternative creates a technically meaningful difference when compared with the relevant patent claim.

Why Should You Start With the Patent Claims?

When people first review a patent, they often focus on its title, drawings, abstract, or overall idea.

But the claims are especially important because they define the scope of patent protection.

Instead of asking:

“Does our product look similar to this patent?”

ask:

“Which requirements of this claim appear in our product?”

This helps identify the specific feature, relationship, component, or process step creating concern. Once that point is understood, the engineering team can explore alternative technical approaches more effectively.

What Can Be Changed?

The answer depends on both the patent claim and the product. A team might:

Remove a feature
Replace a component
Change how components interact
Modify a process or sequence
Use a different system architecture
Adopt a different technical principle

For example, a mechanical sensing method might be replaced with an optical sensing approach, or a direct connection might be redesigned using a different architecture.

The alternative should be technically meaningful, rather than merely giving the same feature a different name or appearance.

Is One Small Change Enough?

Not automatically

Changing one component, shape, position, or label does not by itself establish that a patent concern has been resolved. The redesigned product should be compared with the relevant claim as a whole.

Depending on the applicable law and circumstances, the analysis may also need to consider whether a modified element could still be treated as equivalent to a claimed element.

For this reason, design-around should be approached as a combination of technical redesign and careful patent analysis, rather than as a cosmetic product modification.

Does Finding a Similar Patent Mean Your Product Infringes It?

Not necessarily

General similarity between a patent and a product does not by itself establish infringement. The relevant patent claims need to be compared with the actual product, including its components, relationships, processes, and operation.

This is why relying only on a patent title, drawing, abstract, or overall concept can create the wrong impression.

Is Design-Around the Same as Freedom to Operate?

No.

A design-around analysis typically focuses on a particular patent or claim and asks:

“Can the product achieve its objective through another technical approach?”

A Freedom-to-Operate (FTO) review is broader. It considers relevant patent rights that may affect commercialization of the product in a particular market.

Successfully developing an alternative to one patent claim therefore does not necessarily address other patents that may cover different aspects of the product.

Design-around can support an FTO strategy, but it does not replace a broader FTO review or qualified legal analysis where one is needed.

Why Does Early Review Matter?

Patent concerns are generally easier to address while engineers still have flexibility to modify the product.

Consider these two development paths:

Patent review → Explore alternatives → Prototype → Development

Finished product → Tooling/manufacturing → Patent concern → Major redesign

When concerns are identified before major engineering, tooling, manufacturing, or launch investments are locked in, teams may have more flexibility to evaluate alternative approaches.

Early analysis can therefore support both technical and business decision-making.

Can a Design-Around Create New Innovation?

Sometimes. A patent concern may force an engineering team to ask:

“Is there another way to solve this problem?”

The resulting alternative might:

Simplify the architecture
Improve performance
Reduce manufacturing complexity or cost
Introduce a different technical mechanism
Create a new product differentiator

If the redesigned solution introduces a new and potentially inventive technical approach, it may also be worth evaluating separately for patentability.

In that sense, design-around research can sometimes move beyond risk management and become an innovation opportunity.

What Should You Do If a Patent Claim Creates Concern?

A practical process is:

Understand the claim → Compare the product → Identify the point of concern → Explore technical alternatives → Review the redesigned product → Check other relevant patent rights

The objective is to turn patent uncertainty into a clearer product-development decision.

Concerned About a Patent Claim?

Finding a relevant patent does not always mean your product journey has to end.

The first step is understanding what the claim actually requires and which part of your product creates the concern.

Novel Patent Services supports startups, innovators, R&D teams, and businesses with patent claim analysis, FTO research, patent landscape analysis, design-around research, prior-art searching, patent drafting, and IP strategy support.

Understand the claim. Identify the concern. Explore the options.

Frequently Asked Questions

What is a patent design-around?

A patent design-around involves reviewing the requirements of a patent claim and exploring whether the product can achieve its intended goal through a meaningfully different technical solution.

Does finding a similar patent mean my product infringes it?

Not necessarily. General similarity alone does not establish infringement. The relevant claims need to be compared with the actual product and how it operates.

Can changing one component be enough?

Sometimes, but not automatically. Whether a change matters depends on the relevant claim and how the redesigned product actually works.

Is design-around the same as Freedom to Operate?

No. Design-around generally focuses on particular patent claims, while an FTO review considers relevant patent rights more broadly in connection with commercialization.

Does a design-around guarantee non-infringement?

No. A design-around may address a specific patent claim concern, but other claims or patents may still be relevant. The redesigned product may require broader Freedom-to-Operate and qualified legal review in the relevant jurisdiction.

When should design-around analysis begin?

Ideally, while the product team still has enough engineering flexibility to evaluate alternative technical approaches before major development or manufacturing investments are made.

Can a redesigned solution be patented?

Potentially. If the redesign introduces a new technical approach, it may be worth evaluating separately for patentability.
