Understanding patent infringement is essential for any business that develops new products, relies on proprietary technology, or operates in a competitive market where innovation drives growth. Even unintentional infringement can lead to costly disputes and the loss of valuable rights—making it critical to know what patents cover, how infringement is determined, and what steps companies can take to protect themselves.

A person or entity engages in patent infringement when they engage in the unauthorized use, sale, or manufacture of a patented invention. Claims alleging patent infringement are governed by the Patent Act, 35 USC §§ 1-390, which is a federal law.
For instance, a company may obtain a patent through the U.S. Patent and Trademark Office (USPTO) for a unique product that it develops, markets, and sells. If another company starts manufacturing and selling an identical or substantially similar product without the patent holder’s permission or a license, they are engaging in patent infringement. When this situation occurs, the patent holder can file a patent infringement claim in federal court. Potential remedies in a patent infringement claim may include damages and an injunction prohibiting further infringement.
Taking legal steps to counter patent infringement is important for various reasons. Most importantly, patent holders must enforce their patent rights to protect their business interests, market share, patent portfolio, and potential profits. Not only can patent infringement claims deter future infringement, but they also protect the patent holder’s rights to continue using or selling its products.
Enforcing your patent rights can also create opportunities for additional business through licensing. For example, an infringement claim may result in a negotiated licensing agreement that allows the infringer to continue using the patent in some fashion. Licensing agreements create additional income and profits for the patent holder.
Patent infringement claims can result in an award of monetary damages in favor of the patent holder. Damages in this type of lawsuit can compensate the patent holder for lost profits, royalties, or other financial losses resulting from patent infringement.
Various situations can lead to patent infringement litigation. For example, if one company accuses another company of patent infringement, the alleged infringer may argue that the patent is legally invalid or unenforceable. The infringer could base its invalidity argument on lack of novelty, obviousness, or other grounds.
Another type of patent infringement litigation involves disputes over whether a product or process infringes upon a patent. These cases often center on comparisons between the patented invention and the allegedly infringing product or process, or the interpretation of patent claims.
Some patent infringement litigation doesn’t involve actual patent infringement but may nonetheless involve a violation of patent rights based on indirect infringement or the doctrine of equivalents. For example, indirect infringement, which may consist of contributory or induced infringement, occurs when someone contributes to or encourages another party to engage in direct patent infringement. On the other hand, the doctrine of equivalents provides for patent infringement in some cases even where no literal patent infringement exists. Under this doctrine, a patent holder can claim infringement if the accused product or process performs substantially the same function in substantially the same way, to achieve substantially the same result as that covered by the patent.
Another type of patent infringement litigation occurs when an alleged infringer contends that the patent holder failed to provide proper notice of their patent rights. A lack of notice (such as failure to mark products with a patent number) could reduce the calculation of damages in a patent infringement case.
Accidental infringement often happens when companies develop new products without fully understanding the existing patent landscape. Monitoring competitor filings and reviewing USPTO databases can help identify potential conflicts early. Many businesses also work with IP attorneys to evaluate product designs, assess risk, and adjust features before launch. Taking these steps proactively is far less costly than defending an infringement claim later.
A cease‑and‑desist letter is a serious warning, but it does not automatically mean the company is liable. The first step is to avoid responding impulsively and consult an intellectual property attorney who can evaluate the claims, review the patent, and determine whether infringement is likely. In some cases, the patent may be invalid, the product may not fall within the patent’s claims, or a licensing agreement may be a viable solution. A strategic, informed response helps protect your rights and avoid escalating the dispute.
Yes. Patent protection does not depend on whether the patent holder is actively selling the invention. If another party uses, makes, or sells the patented technology without authorization, the patent owner can still pursue legal remedies. In fact, early enforcement can prevent competitors from gaining market traction and preserve the patent’s value for future commercialization or licensing opportunities.
