Types of Patents for Startups: Utility, Design, Plant
The United States has three types of patents: utility patents protect how something works, design patents protect how an article looks, and plant patents protect certain new plant varieties. A provisional application is not a separate type of patent. It is a low-formality placeholder filing that can lead to a utility patent. Most startups with a technical invention care about utility patents.

The three types of patents, in plain words
People say "a patent" as if there were one kind. In the United States there are three, and they protect completely different things. Choosing the wrong one is a common and expensive mistake, because a patent only covers what it was written to cover.
The USPTO (the United States Patent and Trademark Office, the federal agency that examines and grants patents) describes these categories on its page about types of patent applications. Here is the short version.
- Utility patent: protects a new and useful process, machine, article of manufacture, or composition of matter, or a useful improvement of one. In everyday terms: how something works or what it does.
- Design patent: protects the new, original, ornamental design of an article of manufacture. In everyday terms: how something looks.
- Plant patent: protects a distinct, new variety of plant that has been asexually reproduced (for example, by cuttings or grafting rather than seeds). In everyday terms: a new kind of plant.
Two more terms cause confusion. A provisional application and a non-provisional application are not types of patents. They are stages or filing routes. Both can relate to a utility invention. We cover them in their own section below.
If you are still deciding whether to pursue patents at all, read do I need a patent for my app first. Many startups never need one, and the decision should come before the choice of type. Wysebridge's free guide to U.S. patent law is a good place to learn the basic vocabulary.
Utility patents: how it works and what it protects
The utility patent is the one most people mean when they say "patent." It is the workhorse for technology startups.
What a utility patent covers
The law lists four broad categories of things you can protect with a utility patent:
- Process: a method of doing something, such as a manufacturing method or a method of processing data.
- Machine: a device with working parts, such as a new kind of sensor assembly.
- Article of manufacture: a made object, such as a new type of fastener.
- Composition of matter: a material or mixture, such as a new alloy or formulation.
An invention has to clear several hurdles to be patentable: it must be new, not obvious to a person skilled in the field, useful, and described well enough that others could make and use it. Abstract ideas, laws of nature and natural phenomena are not patentable on their own. This matters a great deal for software, which we cover below.
Claims are the whole game
A utility patent ends with claims: numbered sentences that define the exact boundary of what you own. The rest of the document explains the invention, but the claims are what get compared to a competitor's product if you ever need to enforce the patent. Broad claims are more valuable and harder to get. Narrow claims are easier to get and easier to design around.
How long a utility patent lasts
A U.S. utility patent generally lasts 20 years from the date you file the application, not from the date it is granted. Because examination takes time, the usable life after grant is shorter than 20 years. A patent holder must also pay maintenance fees at set points after grant, or the patent expires early. The USPTO explains this on its pages about maintaining a patent. Some patents get small term adjustments for USPTO delays, so the exact end date for a given patent is something a patent practitioner can calculate.
For a step-by-step view of getting from idea to granted patent, see our guide to the patent process for startups. You can also read the primary source: the Manual of Patent Examining Procedure is the rulebook examiners follow, free to search.
Design patents: what they are and what they are not
A design patent protects the way an article looks, not the way it works. If a competitor can make the same functional product in a different-looking shell, a design patent will not stop them. If a competitor copies your distinctive look, a design patent can.
What a design patent covers
The protected subject is the ornamental design of an article of manufacture. "Ornamental" means the appearance is not dictated purely by function. The application is mostly drawings, and the claim is, in essence, "the ornamental design as shown." Examples of the kinds of things people seek design patents for include the shape of a bottle, the outline of a wearable device, the appearance of a piece of furniture, or the look of a hardware product enclosure.
How a design patent differs from a utility patent
- Scope: appearance only. No protection for how the thing works.
- Content: drawings with a short claim, rather than long technical text and many claims.
- Term: design patents last for a shorter period than utility patents, and the clock is measured differently. For applications filed in recent years the term is generally 15 years from grant, but terms have changed over time, so confirm the rule for your filing date with the USPTO or a practitioner. Design patents do not have maintenance fees in the way utility patents do; check the current USPTO guidance.
- Speed and cost: typically simpler and cheaper than a utility application, though cost varies with the practitioner and the number of drawings. Ask for a quote.
Software patents vs design patents for a UI
A common founder question is whether to protect an app's interface with a design patent or a utility patent. They protect different things. A design patent can protect the ornamental look of certain screen elements when they are tied to an article, such as an icon or display on a device, depending on how the application is drafted. It does not protect what the software does. A utility patent can potentially protect a novel technical method that the software performs, but an idea that is merely an abstract business method is difficult to patent in the United States. Many app features fall into that difficult zone.
The practical lesson: a pretty interface is more reliably protected by copyright (for the code and some creative content) and by trademark (for the brand elements) than by a patent. Read copyright for software startups to see what copyright adds. A registered patent practitioner can tell you whether anything in your interface or method is worth filing.
Plant patents, briefly
Plant patents are a narrow category. They protect a new, distinct variety of plant that has been reproduced by asexual means, such as grafting or cuttings. Sexually reproduced (seed-grown) plants and tuber-propagated plants are handled differently in the law, and some of those are covered by other kinds of plant protection.
Unless your startup breeds ornamental plants, roses, fruit trees or similar crops, you will not use this category. If it is relevant to you, work with a practitioner who handles plant matters. The rest of this guide focuses on utility and design patents because they are the types that matter to most founders.
Provisional vs non-provisional patent applications
These two terms describe how you file a utility application, not what kind of patent you end up with.
Provisional application
A provisional patent application is a filing that establishes an early filing date. It is never examined and never becomes a patent by itself. It stays on file for 12 months. If you want patent protection, you must file a non-provisional application within that 12 months and claim the benefit of the provisional's date. If you do nothing, the provisional simply lapses.
The value is time and a date: you can say "patent pending" and you have a priority date while you test the market, build the product or look for funding. The risk is that a thin, poorly written provisional does not support the later claims, so the early date may be worth less than you think. We explain this in detail in provisional patent for startups.
Non-provisional application
A non-provisional application is the regular filing that gets examined. An examiner searches for prior art (earlier public information about the same subject), reviews your claims and usually issues rejections that you respond to, back and forth, before a patent is granted or the application is abandoned. This is the application that can actually mature into a utility patent. The process often takes years.
Side by side
| Feature | Provisional | Non-provisional (utility) |
|---|---|---|
| Examined by the USPTO? | No | Yes |
| Can become a patent? | No, not on its own | Yes |
| Lifespan | 12 months, then expires | Until grant or abandonment; patent term generally 20 years from filing |
| Needs claims? | Not required, though the description must be thorough | Yes |
| Main purpose | Secure an early date, buy time | Obtain an enforceable patent |
Design and plant applications work differently. Design applications are not filed as provisionals in the same way; talk to a practitioner about the options for protecting a design while you decide.
Comparison: which type protects what
Use this table to match the type to the thing you want to protect. It is a general guide, not advice about your invention.
| Type | Protects | Generally lasts | Best for |
|---|---|---|---|
| Utility patent | How an invention works or what it does | 20 years from filing, subject to maintenance fees | New machines, processes, materials, some technical software methods |
| Design patent | Ornamental appearance of an article | Shorter than utility; confirm the rule for your filing date | Products with a distinctive look |
| Plant patent | A new, asexually reproduced plant variety | Differs; confirm with a practitioner | Plant breeders |
| Provisional application | Nothing alone; holds a filing date | 12 months | Early-stage inventors who need time |
Which patent do I need for my product? Examples
These hypothetical examples show how the choice tends to work. They are illustrations, not predictions, and whether any of them is actually patentable depends on prior art and the specifics.
A new kind of water bottle with a distinctive shape
If the novelty is the look, a design patent may fit. If it also has a new valve mechanism, a utility patent could protect the mechanism, and a design patent could protect the shape. Many physical products use both.
A sensor with a new way of measuring something
The invention is a technical method and apparatus. A utility patent is the relevant type. A provisional application may be a sensible first step if you are not ready for a full filing.
A consumer app with a clean interface and a recommendation feature
The interface look is mainly protected by copyright and your brand by trademark. A design patent is only a narrow option. A utility patent on the recommendation approach depends on whether it is a concrete technical improvement or an abstract idea, which is a hard question. Start with do I need a patent for my app, and consider whether keeping it as a trade secret is a better fit.
A new fertilizer blend
A composition of matter. A utility patent is the relevant type, if it is new and non-obvious. A trade secret may be the alternative.
A new rose variety
A plant patent is the relevant type.
Where this fits in the startup lifecycle
This guide is the "U" step of the Startup Lifecycle A to Z, and it sits in the Build stage. You are deciding what to protect while you make the product. The guide before it in the series is terms of service and privacy policy for startups, which covers the customer-facing documents around your product. The guides after it are IP and startup valuation and what happens to IP when you sell or shut down.

Mistakes to avoid and next steps
Common mistakes
- Publicly disclosing the invention first. Demos, pitch decks posted online, launches and conference talks can start clocks or destroy rights, especially outside the United States. Talk to a practitioner before you disclose.
- Assuming a design patent protects how it works. It does not.
- Treating a provisional as a patent. It is a placeholder. It expires in 12 months.
- Filing a thin provisional. A vague description may not support the claims you later want.
- Skipping the ownership paperwork. The patent belongs to the inventor unless it has been assigned.
What to do this week
- Write down what is new about your product: how it works, how it looks, or both.
- Decide whether each piece is best protected by a patent, a trade secret, copyright or a trademark.
- Check what you have already made public and when.
- Talk to a registered patent attorney or agent. You can search the USPTO's public roster of registered practitioners, or use Wysebridge's directory of USPTO-registered patent attorneys and agents that is built from it.
Frequently asked questions
What are the three types of patents?
Utility patents protect how an invention works, design patents protect the ornamental appearance of an article, and plant patents protect certain new plant varieties reproduced asexually. Provisional and non-provisional are filing routes, not separate kinds of patent. Most technology startups focus on utility patents, sometimes combined with a design patent for a distinctive product look.
What is a design patent?
A design patent protects the new, original, ornamental design of an article of manufacture, meaning how it looks rather than how it works. The application is mainly drawings. It can stop a competitor from copying a distinctive appearance, but not from building a product that works the same way in a different-looking form.
What is the difference between a provisional and a non-provisional patent?
A provisional application is never examined, cannot become a patent alone, and lasts 12 months. It holds an early filing date. A non-provisional application is examined by the USPTO and can mature into a utility patent. To keep the provisional's date, you generally file the non-provisional within the 12 months.
How long does each type of patent last?
A U.S. utility patent generally lasts 20 years from the filing date, subject to maintenance fees. Design patents have a shorter term that is counted differently, and the rules have changed over time, so confirm the term for your filing date. A provisional application lasts 12 months. Plant patent terms should be checked with a practitioner.
Which patent do I need for my product?
It depends on what you want to protect. If the value is in how it works, a utility patent. If the value is in a distinctive look, a design patent. Many hardware products use both. For software, first ask whether a patent is realistic at all. A registered patent practitioner can assess your specific invention.
Can I get a design patent for my app's user interface?
Possibly, in limited cases, depending on how the application is drafted and how the interface relates to an article such as a device display. A design patent covers appearance only, not what the software does. Copyright and trademark often protect an app's look and brand more reliably. Ask a practitioner whether a design filing makes sense.
