Navigating the world of patents can be complex. Understanding patent infringement is crucial for inventors, businesses, and legal professionals alike.
It’s also important to understand strategies for avoiding patent infringement if you are considering patenting an idea. This knowledge can help you navigate the patent landscape with confidence.
In this article, we will delve into what constitutes infringement, the implications of infringing on a patent, and how a patent attorney can help you protect your intellectual property effectively.
What is Patent Infringement?
Patent infringement is a legal term. It refers to the act of making, using, selling, or importing a patented invention without the patent owner’s permission.
A patent is a legal right granted by a government that gives the patent owner the exclusive right to make, use, sell, or import the invention for a certain period. This right is crucial for protecting intellectual property.
Infringement occurs when these exclusive rights are violated. This can happen in various ways, such as directly copying the invention or creating a product that is substantially similar to the patented invention.
The specifics of what constitutes infringement can be complex. They depend on the type of patent, the claims made in the patent, and the laws of the country where the alleged infringement occurs.
It is the responsibility of the patent holder to enforce their patent, with the help of a seasoned patent attorney, if they identify a potential infringement.
Types of Patents and Their Infringement
There are three main types of patents: utility, design, and plant. Each type protects a different aspect of an invention and has its own rules for infringement.
- Utility patents protect new and useful processes, machines, manufactures, or compositions of matter.
- Design patents protect new, original, and ornamental designs for an article of manufacture.
- Plant patents protect new and distinct, invented or discovered asexually reproduced plants.
Utility Patents and Infringement
Utility patents are the most common type of patent. They protect the way an invention works.
Infringement of a utility patent occurs when someone makes, uses, sells, or imports a product that falls within the claims of the patent. The claims define the scope of the protection granted by the patent.
The key to determining infringement is the “all elements” rule. This rule states that infringement occurs if every element of a claim is found in the accused product. If the accused product only contains some of the claims to the original patent, it is not considered infringement.
The all elements rule ensures patent owners are only able to enforce their patent against products that truly infringe on all of their claims, rather than on products that may have similarities. If you have a patent and are unsure if another product is infringing on your patent, we recommend consulting a patent attorney to determine whether or not the accused product infringes on all of your patents’ claims.
Design Patents and the Infringement Test
Design patents protect the way an invention looks. They cover the ornamental design of a functional item, such as shape, configuration or surface decoration.
Infringement of a design patent occurs when an accused product is substantially the same as the patented design when viewed by an “ordinary observer” – i.e. someone who has no specialized knowledge on the subject matter. This is known as the “ordinary observer test.”
The test considers the overall appearance of the design, not just individual features. It’s important to note that even small changes can make a design non-infringing.
Direct vs. Indirect Infringement
Direct infringement is the unauthorized use of a patented invention. It occurs when someone makes, uses, sells, or imports a product that falls within the claims of the patent without the patent owner’s permission.
Indirect infringement, on the other hand, involves contributing to or inducing another’s direct infringement. An example of this could be selling or importing a product that falls within the patent’s claims.
Contributory infringement occurs when a person provides a component of a patented invention knowing it’s especially made for use in infringing the patent. Inducement of infringement happens when a person actively encourages or aids another to infringe a patent.
Understanding the difference between direct and indirect infringement is crucial in patent law. If you think someone may be infringing on your patent, we recommend consulting a patent attorney, like Schell IP, to determine the best course of action.
Consequences of Patent Infringement
Patent infringement can lead to serious legal and financial consequences, if the patent owner chooses to enforce their patent. The patent owner may sue the infringer in federal court and seek damages. These damages can be substantial, often calculated based on the profits lost due to the infringement.
In addition to monetary damages, the court may issue an injunction. This is a court order that stops the infringer from continuing the infringing activity, meaning in some cases that they have to stop selling or distributing the product. In some cases, the infringer may also be ordered to destroy or hand over the infringing products.
Moreover, if the infringement is found to be willful, the court may award treble damages. This means the infringer could be ordered to pay three times the actual damages suffered by the patent owner. This is designed to deter intentional and egregious acts of infringement.
In addition to these consequences, the court may also order the infringer to pay the patent owner’s attorney fees. This can be more common in willful infringement cases, where the infringer knowingly violated the patent.

Proving Infringement in Court
Proving patent infringement in court can be complex. It requires a detailed analysis of the patent claims and the accused product or process. We always recommend consulting a patent attorney when filing a patent infringement case.
The patent owner must show that the accused product or process infringes on all elements of at least one claim of the patent. This can be done through a side-by-side comparison of the language of the patent claims with the features of the accused product or process. Your attorney may also choose to call on expert witnesses, who can provide technical and scientific expertise.
In some cases, the court may also consider the doctrine of equivalents. This doctrine allows a court to find infringement if the accused product or process is similar to an existing patent, even if it does not infringe on all patent claims.
Strategies to Avoid Patent Infringement
If you are working on an invention, startup, or business, you may want to take special care to avoid infringing on an existing patent. One effective strategy is conducting a freedom-to-operate analysis. This involves searching existing patents to ensure that a new product or process does not infringe on existing patent rights.
Another strategy is to design around existing patents. This involves creating a product or process that achieves a similar result but does not infringe on the specific claims of an existing patent.
Lastly, staying current with changes in patent law and court rulings is essential. You should always consult a patent attorney to stay up to date and to do a thorough analysis of recent patents and rulings. This can help businesses and inventors understand the evolving landscape of patent infringement and take appropriate steps to avoid potential legal issues.
