Patents Expiring in 2032

112 U.S. patents losing protection later in the decade, by assignee and technology class.

112 U.S. patents are scheduled to expire in 2032, later in the decade. The full list below is built from USPTO patent records — every entry shows the assignee, expiration date, and CPC technology class as filed with the U.S. Patent and Trademark Office.

What the 2032 Cohort Looks Like

A focused cohort of 112 U.S. patents expires in 2032. While not a headline cliff year by total count, the company-by-company impact can still be meaningful — a single drug or product line losing exclusivity often involves only a handful of listed patents.

Huawei sits at the top of the 2032 expiration list with 6 patents, followed by Honda (6) and IBM (5). Concentrated expirations in a single assignee often signal a coordinated product family reaching the end of its patent life — a pattern most visible in pharmaceutical compound families and consumer electronics platforms.

Among technology classes, Computing & Data Processing leads the 2032 expirations with 126 patents, with Telecommunications the next-largest cluster (123). The mix of CPC classes in a single year provides a reasonable map of which technology areas are about to see a step-change in new entrants and lower licensing pressure.

Why These Expirations Matter

When a U.S. patent expires, its claims enter the public domain. For pharmaceutical patents, that is the trigger that lets generic manufacturers file an Abbreviated New Drug Application under the FDA approval process using the brand drug\'s safety data — a pathway that typically delivers 80–95% list-price drops within 12–18 months. For non-drug patents (semiconductors, consumer electronics, industrial equipment), expiration usually translates directly into competitive entry without the regulatory delay.

Cross-reference any drug-related expiration on this page with the FDA Orange Book, which lists all currently in-force exclusivities and patents tied to approved drug products. The Orange Book exclusivity dates can extend market protection past the patent expiration shown here.

How 2032 Compares to Adjacent Years

The previous expiration year, 2031, saw 117 patents lose protection, and the following year, 2033, has 104 on the books — putting 2032 in between as a transitional year.

How These Expirations Are Calculated

Each expiration date is computed from USPTO patent records using the standard 20-years-from-earliest-non-provisional-filing rule. Patent Term Adjustments (granted to compensate for USPTO processing delays) and Patent Term Extensions (granted under the Hatch-Waxman Act for time lost during FDA review) are applied where present in the federal record. For pharmaceutical patents, FDA-granted exclusivities can extend market protection past the patent expiry shown here — those are tracked separately on each drug profile. Read the full methodology for the data pipeline and known limitations.

Frequently Asked Questions

How many patents are expiring in 2032?

112 U.S. utility patents tracked by PatentCliff are scheduled to lose protection in 2032. That count comes directly from USPTO records using the standard 20-years-from-earliest-non-provisional-filing rule, with Patent Term Adjustments and Patent Term Extensions applied where the federal record specifies them.

Which companies have the most patents expiring in 2032?

Huawei leads with 6 patents, followed by Honda (6), IBM (5), Bayer (5). Concentrated expirations in a single assignee often track to a specific product family — pharmaceutical compound families, semiconductor process generations, or consumer electronics platforms tend to cluster.

What happens when a U.S. patent expires?

When a patent expires, the technology it covers enters the public domain. Anyone can manufacture, use, or sell products based on the expired patent without licensing or royalty payments. For drug patents specifically, expiration is a precondition for generic competition — but FDA-granted exclusivities can extend market protection past patent expiry, and method-of-use patents may remain in force even after the compound patent expires. For non-drug patents, expiration is more straightforward and typically translates into immediate competitive entry.

Are these dates final?

The expiration dates shown reflect the current USPTO record as of 2026-04-10. Dates can shift in two ways: USPTO can grant a Patent Term Adjustment correcting for prosecution delays, or the manufacturer can secure a Hatch-Waxman Patent Term Extension on a drug patent that compensates for FDA review time. Both adjustments appear in the federal record and are reflected here when present. Always confirm against the live USPTO record before making a downstream decision.

Where can I verify these patent expirations?

Every patent in the table below carries its USPTO patent number. You can verify any individual patent through USPTO Patent Public Search (ppubs.uspto.gov), Google Patents, or — for drugs — the FDA Orange Book listings. The federal source is always authoritative; this page is a structured presentation of those records, not an independent calculation.
