"Comprise" and "include" are often used interchangeably in everyday language, but they have different nuances and rules of usage, especially in technical or formal writing.
Key Differences
-
"Comprise" means "consist of" and implies completeness.
- The whole is made up of the listed parts, and nothing else.
- Example:
- The committee comprises five members. (It has exactly five members.)
- The machine comprises a motor, a gearbox, and a control unit. (These are all the essential parts.)
-
"Include" means "contain as part of a larger whole" and suggests incompleteness.
- It implies that the listed items are just some of the components, but not necessarily all.
- Example:
- The committee includes five members. (There may be more than five members.)
- The machine includes a motor and a gearbox. (There might be other parts as well.)
Are They Always Interchangeable?
No, they are not always interchangeable, especially when precision matters.
-
If you mean the entire composition of something, use "comprise".
- The package comprises a user manual, a charger, and the device. (These are all the components.)
-
If you mean only some of the components, use "include".
- The package includes a charger. (There may be other items as well.)
Common Usage Notes
-
"Comprise" is used in an active form and does not require "of" (although "comprised of" is common in informal use, it is considered incorrect in strict formal writing).
- ✅ The system comprises three modules.
- ❌ The system is comprised of three modules. (Considered incorrect in formal writing.)
-
"Include" is more flexible and can be used in passive voice.
- ✅ The system is included in the package.
- ✅ The package includes a user manual and accessories.
Summary
Word | Meaning | Implies Completeness? | Example |
---|---|---|---|
Comprise | Consist of | ✅ Yes, all parts are listed | The car comprises an engine, a chassis, and wheels. |
Include | Contain as part of a whole | ❌ No, other parts may exist | The car includes a GPS system. (It has other parts too.) |
In casual writing, the difference is often ignored, but in precise technical or legal contexts, choosing the correct word can be important.

Yes, in patents, the verb "comprise" is generally used as an open-ended, non-limiting term, meaning "includes but is not limited to." This is a key distinction from its stricter meaning in general English, where it typically implies completeness.
"Comprise" in Patent Claims
- In patent claims, "comprise" does not imply that the listed elements are the only components present.
- It allows for additional unlisted elements, making the scope broader.
- Example:
- A device comprising a motor, a battery, and a control circuit.
- This means the device must have at least these three components, but it may also have additional ones.
"Include" in Patent Claims
- "Include" is also used in a non-limiting way, similar to "comprise."
- However, "comprise" is the preferred term in patent drafting because it has been consistently interpreted in case law as open-ended.
- Example:
- A device including a motor, a battery, and a control circuit.
- This would also be understood as open-ended, but "comprise" is the more standard choice in patents.
"Consist of" as a Limiting Term
- "Consist of" is used when the intent is to exclude any additional elements.
- Example:
- A device consisting of a motor, a battery, and a control circuit.
- This means the device must have only these three components and nothing else.
Summary
Term | Meaning in Patents | Limiting? |
---|---|---|
Comprise | Includes, but is not limited to | ❌ No (open-ended) |
Include | Contains as part of a whole, may have more | ❌ No (open-ended, but less common than "comprise") |
Consist of | Contains only the listed elements, nothing more | ✅ Yes (closed/limiting) |
Thus, in patent claims, "comprise" is almost always the preferred choice because it keeps the scope broad, making it harder for competitors to design around the claim.
