A Brighton product liability lawyer who stands with you.

We trust the products in our homes, our cars and our workplaces to be safe. When one is not — when a design is dangerous, a manufacturing flaw slips through, or a warning is missing — the injury that follows is not the user’s fault. It is the responsibility of the companies that designed, made and sold the product.

Those companies have lawyers and insurers whose job is to deny that anything was wrong. As a dedicated Boston product liability practice, Larson Law investigates how the product failed, preserves it as evidence, works with the right engineering and medical experts, and holds every company in the chain of distribution accountable under Massachusetts law. There is no fee unless we win.

These are among the most complex injury cases, often pitting an individual against a national manufacturer. Winning them takes early investigation, technical proof and the willingness to try the case, all of which we bring from the start.

Because the defendant is often a large company with deep resources, the individual who was hurt can feel outmatched. That is exactly the imbalance we exist to correct. We bring the investigation, the experts and the trial readiness that make a manufacturer take a claim seriously, so that being one person against a corporation does not decide the outcome of your case.

How a Massachusetts product liability claim works.

Two paths to holding a maker responsible

Massachusetts lets an injured person pursue a defective-product claim on two grounds at once: negligence, which asks whether the company failed to use reasonable care in designing, making or marketing the product; and breach of the implied warranty of merchantability, which asks simply whether the product was defective and unreasonably dangerous. The second path does not require proving carelessness at all, which is why it is so important here.

Breach of warranty — Massachusetts’s version of strict liability

Unlike most states, Massachusetts does not use a separate strict-liability tort. Instead, the implied warranty of merchantability under General Laws chapter 106, section 2-314 does that work: every product sold carries an implied promise that it is fit for its ordinary use, and a product that injures someone because it is defective breaks that promise. You do not have to prove the maker was negligent, only that the product was unreasonably dangerous.

The three kinds of defect

Product cases turn on one of three defects. A manufacturing defect means the item left the factory different from its intended design. A design defect means the product is dangerous even when made correctly, because a safer design was feasible. A failure-to-warn, or marketing defect, means the maker did not provide adequate instructions or warnings about a known risk. Identifying which defect applies shapes the entire case.

Manufacturing defects

A manufacturing defect is a flaw introduced in production — a cracked weld, a contaminated batch, a missing part — that makes one unit dangerous even though the design is sound. These cases often depend on comparing the injuring product to the manufacturer’s own specifications and quality records.

Design defects

A design defect makes every unit of a product dangerous. Proving one usually means showing that a safer, practical alternative design existed and would have prevented the injury without destroying the product’s usefulness. This is expert-intensive work, and it is where many product cases are won or lost.

Failure to warn

Even a well-made, well-designed product can be dangerous if its risks are not disclosed. When a manufacturer knows of a hazard and fails to give adequate warnings or instructions, an injury caused by that hidden risk can support a claim. Missing or buried warnings are a common thread in these cases.

Everyone in the chain of distribution

Responsibility for a defective product is not limited to the manufacturer. Distributors, wholesalers and retailers who sold the product can also be liable, which matters when a manufacturer is overseas, out of business or hard to reach. We identify every company in the chain and every applicable insurance policy.

Unfair practices and the consumer protection law

Where a company knowingly sold a dangerous product or acted in bad faith, Massachusetts’s consumer protection statute, chapter 93A, can allow double or triple damages and attorney’s fees on top of the ordinary recovery. Recognizing when 93A applies can significantly change the value of a case.

Defective vehicles and auto parts

Some of the most serious product cases involve motor vehicles: failed brakes, defective tires, airbags that do not deploy or deploy too violently, seat-back and roof failures in a crash, and fuel systems that catch fire. A crash caused or made worse by a vehicle defect can create a product claim against the maker in addition to any claim against another driver, and both should be examined together.

Medical devices and medications

Defective medical devices and drugs are a category of their own — failed implants, contaminated or mislabeled medications, and devices that malfunction during treatment. These cases carry special complexity, including layers of federal regulation, but a patient harmed by a dangerous device or drug may still have a claim, and it is worth having one evaluated by a lawyer who understands them.

Preserving the product is critical

The single most important piece of evidence is usually the product itself. Once it is discarded, repaired or returned, proving the defect becomes far harder, and the law may draw an adverse inference against a party that destroyed it. We act immediately to secure and preserve the product and its packaging.

Building the technical proof

Product cases are won with evidence most people never see: engineering analysis, failure testing, comparison to safety standards and the manufacturer’s own documents, and the testimony of experts who can explain to a jury exactly how and why the product failed. We assemble that team early, because the strength of the technical proof usually determines the outcome.

When a component or another party is involved

Many products are assembled from parts made by different companies, and an injury may trace to a single defective component. Sorting out which company’s part failed — and bringing in every responsible manufacturer and supplier — is often key to a full recovery, and it is work that takes real experience with how these cases are structured.

If you were partly at fault

Using a product in a foreseeable way, even an imperfect way, is not the same as being at fault. Under Massachusetts’s comparative negligence rule, chapter 231, section 85, a claim is reduced by any share of fault assigned to you but not barred unless you were more than half responsible, and manufacturers cannot escape liability simply because a user was not perfect.

Battery fires and burn injuries

Lithium-ion batteries in phones, laptops, e-bikes and scooters can overheat, catch fire or explode, causing severe burns and property damage. As these devices have multiplied, so have the injuries, and a battery, charger or device that fails because of a design or manufacturing defect can support a product claim against the maker and the seller that put it in your hands.

Recalls, regulators and reporting

Federal agencies such as the Consumer Product Safety Commission, the National Highway Traffic Safety Administration and the Food and Drug Administration track dangerous products and order recalls. A recall or regulatory finding can be powerful evidence and can reveal a pattern of harm, but it is not required to bring a claim, and the absence of a recall does not mean a product was safe. We use these records as part of the proof.

The deadline to file

Under chapter 260, section 2A you generally have three years from the injury, or from when you reasonably discovered that a product caused it, to bring a claim. Because these cases require early investigation and preservation of the product, waiting can cost you both evidence and the claim itself.

What a product liability claim can include

Unlike workers’ compensation, a product liability claim seeks the full range of damages: past and future medical care, lost wages and earning capacity, and compensation for pain, disfigurement and the disruption to your life. Where a defect proves fatal, the family may bring a wrongful death claim. A properly built case accounts for all of it.

Where defective products cause injury in Brighton

Dangerous products reach every part of daily life in Brighton — a faulty space heater or lithium battery in a triple-decker apartment, a defective auto part on Commonwealth Avenue, an unguarded machine on a construction site, a recalled appliance in a rental kitchen, or a medical device that fails a patient at St. Elizabeth’s Medical Center. Wherever it happens, the questions are the same: what failed, and who is responsible.

The injuries these cases involve

Defective products cause burns, lacerations, crush and amputation injuries, electrocutions, poisonings, and the serious trauma that follows a vehicle or machinery failure. Because the harm is often severe and the fault lies with a distant company, these claims deserve careful, determined handling.

Common defective products here

In a neighborhood of dense housing, students and small businesses, the products that most often cause injury are everyday ones: portable heaters and power strips, e-bike and scooter batteries, kitchen and cleaning equipment, and the vehicles and parts that fill Brighton’s streets. Familiar does not mean safe, and a common product that fails can cause a very serious injury.

Acting quickly and locally

The first steps — getting medical care, keeping the product, and photographing the scene — often decide a product case. We move quickly to preserve what matters and to build the technical proof, and we know the courts where these Massachusetts claims are heard.

The wider region

Larson Law handles defective-product cases across the area, including as a Cambridge product liability firm, so people beyond Brighton get the same experienced help holding manufacturers accountable.

Unsafe products in rental housing

In Brighton’s many rentals, a defective appliance, heater or smoke detector supplied with the unit can injure a tenant. Depending on the facts, both the product’s maker and, in some cases, a landlord who provided or failed to maintain it may share responsibility. These overlapping claims are worth sorting out carefully, because more than one source of recovery may exist.

When to reach out

The sooner you call, the more of the evidence we can preserve — above all the product itself, before it is repaired, returned or thrown away. Even if some time has passed, a short conversation costs nothing and can tell you whether a claim is still possible.

A claim should cover every lasting cost.

An injury from a defective product can carry costs that last for years — surgeries and rehabilitation, permanent scarring or disability, income lost while you cannot work and earning power lost for good, and the pain and disruption that follow a serious injury. Because a product case seeks the full range of damages, a properly built claim accounts for every one of these, present and future, and it pursues the additional recovery that Massachusetts’s consumer protection law can provide when a company knowingly sold a dangerous product or acted in bad faith.

Simple steps that protect your health and your claim.

Get medical care as soon as you can

See a doctor as soon as possible, and make sure the records describe how the product caused your injury. Prompt care protects your health and creates the medical proof your claim will depend on later.

Keep the product and all packaging.

Do not throw away, return or repair the product that hurt you, and keep the box, manual and receipt if you can. The product itself is commonly the single most important piece of evidence in your case.

Talk to a lawyer before the company

Do not give a recorded statement or accept any offer from the manufacturer or its insurer. Speak with a Brighton product liability lawyer first so evidence is preserved and your rights stay protected.

Product liability claims, answered directly.

Do I have a product liability case?

Possibly, if a product injured you because it was defective or unreasonably dangerous. Massachusetts lets you pursue the claim without proving the company was careless — through the implied warranty of merchantability — as long as the product was flawed in its design or manufacture, or lacked adequate warnings. The key questions are what failed, whether the product caused your injury, and which companies made and sold it. A free case review is the fastest and best way to find out exactly where you stand.

It can matter a great deal. A product that is dangerous in a way an ordinary user would not expect must carry adequate warnings and instructions. When a manufacturer knew of a risk and failed to warn about it — or buried the warning where no one would realistically see it — an injury caused by that hidden danger can support a failure-to-warn claim. Missing, unclear or inadequate warnings are one of the most common grounds for these cases, and always worth examining closely.

It is harder, but not always fatal. The product itself is usually the best evidence, so keeping it is important. If it is already gone, a claim may still be built from photographs, medical records, the product’s manual or packaging, recall notices, and the accounts of witnesses, together with examination of identical products. Tell your lawyer exactly what happened to it; the sooner we know, the more we can do to reconstruct the proof and preserve whatever still remains.

Not necessarily, and that is one of the most important things to understand. Massachusetts is unusual in that you can recover through the implied warranty of merchantability without proving negligence — you need only show the product was defective and unreasonably dangerous and that it caused your injury. You can also pursue a negligence theory at the same time, giving you two paths at once. Being able to win without proving carelessness is a feature that makes Massachusetts product law relatively favorable to injured people.

Any company in the chain of distribution can be responsible: the manufacturer that designed or made the product, the maker of a defective component, and the distributors, wholesalers and retailers that sold it. This matters enormously when the manufacturer is overseas, out of business, or otherwise hard to sue. We identify every responsible company and every insurance policy, so your recovery is not limited by one party’s ability to pay or by a manufacturer you cannot practically reach.

Using a product imperfectly is not the same as being at fault, and manufacturers are required to account for foreseeable misuse. If your use of the product was one the maker could reasonably expect, that generally does not defeat your claim. Even if you were found partly at fault, Massachusetts’s comparative negligence rule reduces a claim by your share rather than barring it, unless you were more than half responsible. The insurer will almost always raise misuse; we are very used to answering that argument.

All kinds. Common product cases involve motor vehicles and auto parts, tires, industrial and construction machinery, power tools, medical devices and implants, pharmaceuticals, household appliances, space heaters and lithium-ion batteries, children’s products and toys, and furniture. If a product failed and injured you — whether it malfunctioned, was poorly designed, or lacked a warning it should have carried — it is worth having reviewed. People often assume a common household item cannot be the basis of a serious case, but familiarity is not the same as safety.

It depends on the severity and permanence of your injury, your past and future medical costs, lost income and earning capacity, and the pain and disruption you have endured. Because product cases seek the full range of tort damages — including pain and suffering — and can include double or triple damages under the consumer protection law when a company acted in bad faith, the value of a strong case can be substantial. We assess all of it carefully before advising you, rather than quoting a figure up front.

Generally three years from the injury, or from when you reasonably should have discovered that a product caused it, under Massachusetts law. Product cases require early investigation and, above all, preservation of the product, so waiting is risky even when the deadline seems far off. If a government entity is involved or a shorter contractual period applies, different limits can come into play, which is one more reason to get advice promptly rather than assume you have plenty of time to spare.

It can help, but it is not the whole case. A recall shows that the manufacturer or a regulator recognized a hazard, which supports the argument that the product was defective, and it can help identify others harmed by the same product. But a claim still requires proving that the specific defect caused your specific injury. We use recall notices and regulatory findings as an important part of the proof, never as a substitute for it.

Nothing up front. Larson Law handles product liability cases on a contingency fee, so our fee comes only as a percentage of what we recover for you — if we recover nothing, you owe no attorney’s fee. Because these cases require engineering experts, product testing and investigation, we advance those often significant costs. That lets an injured person take on a large manufacturer without paying out of pocket while the case is built, and it means cost is never the reason a valid claim goes unpursued.

Get medical care right away, and make sure the records note that a product caused the injury. Then keep the product exactly as it is — do not return, repair or discard it — along with the packaging, manual and receipt, and photograph the product and the scene. Write down what happened, and hold on to any recall information. Before speaking with the manufacturer or its insurer, call a Brighton product liability lawyer so the evidence is preserved and your rights are protected.
