Key Types of Intellectual Property

Why This Matters

Intellectual property law isn't just about memorizing definitions—it's about understanding how different types of creative and innovative work require different forms of legal protection. On your exam, you'll need to identify which IP right applies to a given scenario, explain why one form of protection fits better than another, and analyze the policy trade-offs behind each system. The categories you'll learn here reflect fundamental choices about what we protect, how long we protect it, and what we require creators to do in exchange for that protection.

Think of IP types as existing on several spectrums: formal vs. informal protection (patents require registration; trade secrets don't), fixed vs. renewable duration (copyrights expire; trademarks can last forever), and functional vs. aesthetic coverage (utility patents protect how things work; design rights protect how they look). Don't just memorize the list—know what concept each IP type illustrates and be ready to compare them when an exam question presents a hypothetical invention, brand, or creative work.

Protecting Innovation Through Disclosure

These IP rights reward inventors and creators who share technical or creative details with the public. The underlying bargain: you get exclusive rights for a limited time, and in exchange, society gains knowledge it can build upon once protection expires.

Patents

• Grants exclusive rights for 20 years (from filing date for utility patents)—the inventor can prevent others from making, using, selling, or importing the invention
• Requires public disclosure of how the invention works, including proof of novelty, non-obviousness, and utility—this is the "patent bargain"
• Three main types exist: utility patents (processes, machines, compositions of matter), design patents (ornamental appearance, 15 years), and plant patents (asexually reproduced new varieties)

Plant Variety Protection

• Protects new plant varieties developed through traditional breeding—distinct from plant patents, which cover asexually reproduced plants
• Requires the variety to be DUS: distinct, uniform, and stable—protection typically lasts 20-25 years depending on the crop type
• Includes a breeder's exemption allowing others to use protected varieties for research and developing new varieties—balancing innovation incentives with agricultural progress

Protecting Expression Automatically

Copyright stands apart from most IP rights because it requires no registration, no examination, and no disclosure. Protection attaches the moment an original work is fixed in tangible form.

Copyrights

• Protects original works of authorship including literature, music, visual art, film, and software—but never the underlying ideas, only their expression
• Exclusive rights include reproduction, distribution, public performance, display, and creating derivative works—these rights can be licensed or transferred separately
• Duration extends life plus 70 years for individual authors; works made for hire last 95 years from publication or 120 years from creation, whichever is shorter

Protecting Commercial Identity

These rights help consumers identify the source of goods and services, preventing marketplace confusion. Unlike patents and copyrights, they can potentially last forever as long as they remain in use and distinctive.

Trademarks

• Protects source identifiers including words, logos, slogans, sounds, and even colors or scents that distinguish one company's goods from another's
• Requires distinctiveness—marks range from generic (unprotectable) to fanciful (strongest protection), with descriptive marks needing secondary meaning
• Renewable indefinitely through continued use and maintenance filings—but abandonment through non-use or becoming generic ("genericide") can destroy rights

Geographical Indications

• Links product quality to geographic origin—think Champagne, Parmigiano-Reggiano, or Darjeeling tea, where terroir or regional methods define the product
• Functions as a collective right rather than individual ownership—all qualifying producers in the region can use the designation
• Varies significantly by jurisdiction—the EU treats GIs as a distinct IP category; the U.S. primarily protects them through trademark law as certification marks

Protecting Confidential Information

Trade secrets take the opposite approach from patents: instead of disclosing information in exchange for rights, protection depends on keeping information secret. No registration, no time limit—but no protection if the secret gets out.

Trade Secrets

• Protects valuable confidential business information including formulas (Coca-Cola), algorithms, customer lists, and manufacturing processes—must derive value from secrecy
• Requires reasonable efforts to maintain secrecy—NDAs, access restrictions, and security measures are essential; courts examine what steps the owner actually took
• Permits reverse engineering—if competitors can lawfully figure out your secret by analyzing your public product, that's not misappropriation; only improper acquisition or disclosure violates trade secret law

Protecting Aesthetic and Technical Design

These specialized rights fill gaps between the major categories, protecting specific aspects of product design that might not fit neatly into patent or copyright frameworks.

Industrial Designs

• Protects the ornamental or aesthetic appearance of a product—shape, configuration, pattern, or color that makes it visually distinctive
• Requires registration in most jurisdictions, with protection lasting 15-25 years depending on the country and renewal practices
• Excludes functional features—if a design element is dictated by how the product works, it needs patent protection, not design protection

Mask Works (Semiconductor Chip Protection)

• Protects semiconductor chip topographies—the three-dimensional layout of circuits etched into chips, representing enormous R&D investment
• Registration required, with protection lasting 10 years from registration or first commercial exploitation—significantly shorter than other IP rights
• Created because chips fell through the cracks—too functional for copyright, too obvious for patents, leading to the Semiconductor Chip Protection Act of 1984 in the U.S.

Self-Check Questions

1. A company develops a new manufacturing process that competitors could easily reverse-engineer from the final product. Should they pursue patent protection or trade secret protection, and why?

2. Which two IP types can potentially last forever, and what must the owner do to maintain protection in each case?

3. Compare and contrast how patents and copyrights balance the interests of creators against the public interest. What does each system require in exchange for protection?

4. A designer creates a new chair with an innovative ergonomic feature and a distinctive sculptural appearance. Which IP rights might protect different aspects of this chair, and what would each cover?

5. Why did Congress create a separate category of protection for semiconductor mask works instead of relying on existing patent or copyright law? What gap did this fill?
