Types of Patents Explained: Utility vs Design vs Plant Patents

Quick Answer: What Are the Three Types of Patents?

The United States Patent and Trademark Office grants three distinct types of patents: (1) Utility patents protect how inventions work and function, covering processes, machines, manufactures, and compositions of matter under 35 U.S.C. § 101, lasting 20 years from filing; (2) Design patents protect ornamental appearance and visual design of functional items under 35 U.S.C. § 171, lasting 15 years from grant; and (3) Plant patents protect asexually reproduced distinct plant varieties under 35 U.S.C. § 161, lasting 20 years from filing. Each patent type serves different protection needs, with utility patents being most common (over 90% of granted patents), design patents protecting product aesthetics that drive purchasing decisions, and plant patents covering agricultural and horticultural innovations.

Understanding Patent Types: Choosing the Right Protection

Patent law recognizes that different types of innovation require different forms of protection. A revolutionary new smartphone technology needs different legal protection than the phone's distinctive exterior design. Similarly, a newly developed rose variety requires protection mechanisms distinct from either functional or ornamental innovations.

At Yomtobian Law, we help inventors and businesses determine which patent types best protect their innovations, often recommending multiple patent types for comprehensive protection. Our patent prosecution services cover all three patent types, with particular expertise in utility and design patents for technology and consumer products.

Utility Patents: Protecting Function and Innovation

What Utility Patents Cover

Utility patents, authorized by 35 U.S.C. § 101, protect the functional aspects of inventions. The statute defines patentable subject matter as "any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof."

This broad language encompasses four statutory categories:

Processes: Methods, procedures, or sequences of steps producing useful results. Examples include manufacturing processes, chemical reactions, software algorithms, business methods, and medical treatment methods. In Diamond v. Diehr, 450 U.S. 175 (1981), the Supreme Court held that processes transforming raw materials into different states or things are patentable.

Machines: Devices with moving or stationary parts working together to achieve specific functions. Examples include engines, computers, robots, tools, and mechanical devices. The Federal Circuit in In re Nuijten, 500 F.3d 1346 (Fed. Cir. 2007), defined machines as concrete things consisting of parts or devices.

Manufactures: Articles or products made by human hands or machinery. Examples include furniture, containers, composite materials, and manufactured goods. According to MPEP § 2106, manufactures are tangible articles giving new forms, qualities, properties, or combinations to raw materials.

Compositions of Matter: Chemical compounds, mixtures, and materials. Examples include pharmaceuticals, polymers, alloys, genetically modified organisms, and chemical formulations. The Supreme Court in Diamond v. Chakrabarty, 447 U.S. 303 (1980), held that living organisms could be patentable compositions if they are human-made.

Utility Patent Requirements

Beyond fitting statutory categories, utility patents must satisfy several requirements:

Utility: Inventions must be useful, providing specific, substantial, and credible utility under 35 U.S.C. § 101. This low threshold is easily met for most mechanical and electrical inventions but can challenge pharmaceutical inventions requiring proof of therapeutic utility.

Novelty: Inventions must be new under 35 U.S.C. § 102, not anticipated by any single prior art reference. The America Invents Act established a first-inventor-to-file system making filing dates critical for establishing novelty.

Non-Obviousness: Inventions must not be obvious to persons having ordinary skill in the art under 35 U.S.C. § 103. The Supreme Court in KSR Int'l Co. v. Teleflex Inc., 550 U.S. 398 (2007), held that obviousness analysis requires flexible assessment considering ordinary innovation within fields.

Enablement: Patent specifications must describe inventions sufficiently to enable skilled persons to make and use them without undue experimentation under 35 U.S.C. § 112(a).

Utility Patent Duration and Maintenance

Utility patents last 20 years from filing date (or earliest priority date for continuation applications) under 35 U.S.C. § 154(a)(2). Patent owners must pay maintenance fees at 3.5, 7.5, and 11.5 years to keep patents in force:

• 3.5 years: $1,600 (large entity), $800 (small), $400 (micro)

• 7.5 years: $3,600 (large entity), $1,800 (small), $900 (micro)

• 11.5 years: $7,400 (large entity), $3,700 (small), $1,850 (micro)

Failure to pay maintenance fees results in patent expiration. According to USPTO statistics, approximately 15% of utility patents expire before their full terms due to unpaid maintenance fees.

Utility Patent Examples

Technology: Apple's multi-touch gesture recognition (U.S. Patent 7,479,949) protecting methods for recognizing touch inputs on screens

Medical Devices: Medtronic's cardiac pacemaker improvements protecting implantable pulse generator configurations

Pharmaceuticals: Pfizer's Lipitor formulation patents protecting atorvastatin calcium compositions for cholesterol treatment

Software: Amazon's one-click ordering (U.S. Patent 5,960,411) protecting electronic commerce methods

Manufacturing: Tesla's battery cell manufacturing processes protecting methods for producing lithium-ion cells

Utility Patent Costs

According to industry surveys, average utility patent costs from filing through grant:

• Simple inventions: $8,000 to $10,000

• Moderate complexity: $10,000 to $15,000

• High complexity: $15,000 to $25,000+

Costs include attorney fees for preparation, filing fees, office action responses, and USPTO fees. Complex technologies requiring extensive prior art analysis, detailed specifications, and multiple office action responses increase costs.

Design Patents: Protecting Appearance and Aesthetics

What Design Patents Cover

Design patents, authorized by 35 U.S.C. § 171, protect "new, original and ornamental design for an article of manufacture." Unlike utility patents protecting function, design patents protect how products look.

The Supreme Court in Gorham Co. v. White, 81 U.S. 511 (1871), established that design patents protect overall visual impressions, not individual features. Infringement occurs when ordinary observers purchasing articles would be deceived into thinking one design is the other.

Protected design elements include:

Shape and Configuration: Three-dimensional product forms like Coca-Cola's contoured bottle or Apple's iPhone shape

Surface Ornamentation: Two-dimensional patterns, textures, and decorative elements applied to article surfaces

Combined Configuration and Ornamentation: Integration of shape and surface design creating distinctive appearances

Design patents cannot protect:

Functional Features: Elements dictated by function rather than aesthetics. In Richardson v. Stanley Works, Inc., 597 F.3d 1288 (Fed. Cir. 2010), the Federal Circuit held that design features primarily serving functional purposes are ineligible.

Hidden Elements: Internal components not visible during normal use

Abstract Designs: Designs not embodied in articles of manufacture

Design Patent Requirements

Design patents require meeting different standards than utility patents:

Ornamentality: Designs must be primarily ornamental, not dictated by functional considerations. According to MPEP § 1504.01, if product appearance is dictated by functional requirements, design patent protection is unavailable.

Novelty: Designs must differ from prior art in more than trivial ways. The Whitman Saddle Co. v. Muellers, 179 F.2d 949 (9th Cir. 1950), test requires examining whether designs are substantially the same as prior designs in appearance.

Non-Obviousness: Designs must not be obvious to designers of ordinary skill. Unlike utility patent obviousness focusing on function, design patent obviousness examines whether prior art designs would suggest claimed appearances to ordinary designers.

Design Patent Duration and Fees

Design patents last 15 years from grant date (for applications filed after May 13, 2015) under 35 U.S.C. § 173. Unlike utility patents, design patents require no maintenance fees, providing 15 years of protection with no additional costs beyond initial prosecution.

This makes design patents particularly cost-effective for protecting product aesthetics over their commercial lifecycles.

Design Patent Strategy

Smart businesses file both utility and design patents for comprehensive protection:

Utility Patent: Protects functional innovations preventing competitors from making products work the same way

Design Patent: Protects visual appearance preventing competitors from making products look the same

This dual strategy forces competitors to design around both function and appearance, creating stronger competitive barriers.

For consumer products where appearance drives purchasing decisions (consumer electronics, furniture, fashion accessories, automotive designs), design patents provide critical protection. For guidance on design patent strategy, consult experienced patent counsel.

Design Patent Examples

Consumer Electronics: Apple's design patents for iPhone, iPad, and MacBook appearances protecting distinctive product designs that command premium prices

Automotive: Tesla's design patents for vehicle exteriors protecting sleek, futuristic appearances that define brand identity

Furniture: Herman Miller's Aeron chair design protecting ergonomic office chair appearance

Footwear: Crocs' distinctive shoe design (U.S. Patent D517,789) protecting recognizable clog appearance

Packaging: Coca-Cola's contoured bottle design protecting one of the world's most recognizable package shapes

Design Patent Costs

Design patent prosecution typically costs less than utility patents:

• Simple designs: $2,500 to $4,000

• Moderate complexity: $4,000 to $6,000

• Complex designs: $6,000 to $8,000

Lower costs reflect simpler application requirements (drawings showing all views, brief specifications, single claim describing design shown in drawings). Most design patents face fewer office actions than utility patents, reducing prosecution expenses.

Plant Patents: Protecting Horticultural Innovation

What Plant Patents Cover

Plant patents, authorized by 35 U.S.C. § 161, protect "any distinct and new variety of plant, including cultivated sports, mutants, hybrids, and newly found seedlings, other than a tuber propagated plant or a plant found in an uncultivated state."

Plant patents protect asexually reproduced plants, meaning plants reproduced by methods other than seeds:

Asexual Reproduction Methods:

• Rooting cuttings

• Layering

• Budding

• Grafting

• Inarching

• Tissue culture

The Supreme Court in J.E.M. Ag Supply, Inc. v. Pioneer Hi-Bred Int'l, Inc., 534 U.S. 124 (2001), held that plant patents, utility patents, and Plant Variety Protection Act certificates provide overlapping but distinct protection for plant innovations.

Plant Patent Requirements

Plant patents require unique elements beyond standard patentability:

Asexual Reproduction: Plants must be reproduced asexually, excluding seed-propagated plants (protected under the Plant Variety Protection Act instead)

Distinctness: Plants must differ from known varieties in at least one distinguishing characteristic that is more than a difference caused by growing conditions or cultural practices

Non-Obvious: New characteristics must not be obvious. According to MPEP § 1601, plant patent obviousness considers whether skilled horticulturists would have expected the new variety's characteristics from parent plants.

Naming: Plant patents require designating variety denominations used in commerce

Deposit: While not always required, depositing plant specimens with recognized depositories may support enablement requirements

Plant Patent Duration

Plant patents last 20 years from filing date under 35 U.S.C. § 161, with no maintenance fees required. Plant patents grant exclusive rights to asexually reproduce plants, preventing others from reproducing, selling, or using patented plant varieties.

Plant Patent Examples

Roses: Thousands of rose varieties are protected by plant patents, including disease-resistant varieties, unique colors, and improved fragrance

Fruit Trees: Apple varieties like Honeycrisp (U.S. Plant Patent 7,197) protecting distinctive flavor profiles and growing characteristics

Ornamental Plants: Unique flower colors, growth habits, and flowering patterns

Berries: Blueberry and strawberry varieties with improved yield, flavor, or disease resistance

Plant Patent Costs

Plant patent prosecution typically costs:

• Application preparation and filing: $4,000 to $7,000

• Including detailed botanical descriptions

• Color photographs or drawings

• Asexual reproduction documentation

Lower application volumes (approximately 1,200 plant patents granted annually versus 350,000+ utility patents) mean less competition and often faster prosecution.

Choosing the Right Patent Type for Your Innovation

Decision Framework

Is Your Innovation Functional? If yes, consider utility patents. Functional innovations solving technical problems, improving efficiency, or providing new capabilities require utility patent protection.

Is Your Innovation Visual? If product appearance is distinctive and ornamental, consider design patents. Consumer products where aesthetics drive purchasing decisions benefit significantly from design patent protection.

Is Your Innovation a Plant Variety? If you've developed new asexually reproduced plants with distinct characteristics, consider plant patents.

Can Multiple Patent Types Apply? Many innovations warrant multiple patent types. A new smartphone might receive:

• Utility patents for internal technology

• Design patents for exterior appearance

• Additional utility patents for software methods

Strategic Combinations

Product Manufacturers: File both utility and design patents. Utility patents protect functionality; design patents protect appearance. Together, they create comprehensive barriers preventing competitors from making products that work the same OR look the same.

Technology Companies: Focus on utility patents for functional innovations, filing design patents for distinctive user interfaces or product designs.

Consumer Goods: Emphasize design patents protecting distinctive appearances that consumers recognize, supplemented by utility patents for unique functional features.

Agricultural Businesses: Use plant patents for new varieties, supplemented by utility patents for propagation methods or genetic modifications.

For strategic guidance on building patent portfolios combining multiple patent types, experienced counsel evaluates innovations holistically and recommends comprehensive protection strategies.

Prosecution Differences Between Patent Types

Application Complexity

Utility Patents:

• Most complex applications

• Detailed specifications (often 20-50+ pages)

• Multiple claims (typically 15-25 claims)

• Extensive prior art searching required

• Average 2-3 office actions before allowance

Design Patents:

• Simpler applications

• Brief specifications (typically 3-5 pages)

• Single claim describing design shown in drawings

• Visual prior art searching

• Average 1-2 office actions before allowance

Plant Patents:

• Moderate complexity

• Detailed botanical descriptions

• Single claim describing plant variety

• Limited prior art (mainly other plant patents)

• Average 1-2 office actions before allowance

Examination Time

According to current USPTO pendency data:

• Utility patents: 16-24 months average to first office action

• Design patents: 12-18 months average to first office action

• Plant patents: 18-24 months average to first office action

Actual grant times depend on prosecution difficulty and number of office action cycles.

International Patent Protection Considerations

Utility Patents Abroad

International utility patent protection requires filing in foreign countries through:

Patent Cooperation Treaty (PCT): File one international application designating up to 150+ countries, deferring national phase filings 30-31 months

Direct Foreign Filing: File directly in foreign patent offices, requiring compliance with local laws and languages

Paris Convention: Claim priority to U.S. filing if filing abroad within 12 months

Design Patents Abroad

International design protection options include:

Hague Agreement: File one international design application covering 90+ countries through WIPO

Direct Foreign Filing: File design applications in target countries

European Community Design: Single application covering all EU member states

Plant Patents Abroad

Plant protection varies significantly by country:

Plant Variety Protection: Many countries use Plant Variety Protection certificates rather than patents

Utility Patents: Some countries allow utility patents for genetically modified or hybridized plants

Regional Systems: EU Community Plant Variety Rights provide pan-European protection

Frequently Asked Questions

Q: Can I get both utility and design patents for the same invention?

Yes, and this is often recommended. Utility patents protect functional aspects; design patents protect ornamental appearance. Together they provide comprehensive protection preventing competitors from copying either function or appearance. Many successful products like iPhones hold both patent types.

Q: Which patent type is most valuable?

It depends on your innovation and industry. Utility patents generally provide broader, stronger protection for functional innovations. Design patents are extremely valuable for consumer products where appearance drives purchasing decisions. Plant patents are essential for agricultural innovations. Value depends on how the patent supports your business model.

Q: Are design patents easier to get than utility patents?

Generally yes. Design patent applications are simpler, require fewer technical details, and face fewer office action cycles. However, design patents still require meeting novelty and non-obviousness standards. Prosecution difficulty varies based on prior art and design uniqueness.

Q: Do design patents require maintenance fees?

No. Design patents require no maintenance fees after grant, providing 15 years of protection with no additional costs. This makes them particularly cost-effective for long-term protection.

Q: Can software be protected by patents?

Yes, through utility patents if software provides technical improvements or solves technical problems beyond implementing abstract ideas on generic computers. The Alice/Mayo framework governs software patent eligibility. User interfaces can sometimes receive design patent protection for distinctive visual appearances.

Q: How long do different patent types last?

Utility patents: 20 years from filing date. Design patents: 15 years from grant date. Plant patents: 20 years from filing date. Only utility patents require maintenance fees.

Q: Can I file a provisional application for design patents?

No. Provisional applications under 35 U.S.C. § 111(b) are only available for utility and plant patents. Design patent applicants must file complete non-provisional applications.

Q: What happens when my patent expires?

The invention enters the public domain. Anyone can make, use, or sell the invention without permission. This is the constitutional bargain: temporary exclusivity in exchange for public disclosure enabling future innovation.

Q: Can I patent naturally occurring plants I discover?

No. Plant patents require human intervention creating distinct varieties through breeding, cultivation, or propagation. Naturally occurring plants, even if newly discovered, are ineligible. However, genetically modified plants or hybrids created through human intervention may qualify.
