AP CSP Copyright, Creative Commons & Open Source: Complete Guide (2025‑2026)

Intellectual property (IP) laws protect creators’ rights to their original works. Copyright applies automatically to any creative work upon creation — no registration needed. Creative Commons licenses let creators share work with specific conditions. Open source software makes source code publicly available. Understanding these distinctions helps developers legally and ethically use others’ work in their programs.

FreeOpen source ≠ free of cost — it means source code is open, not necessarily free

The IP Spectrum

Scenario — Using an Image Found Online

A student finds a photo on Google Images that would be perfect for their website project. They copy and use it without checking.

What intellectual property issues might arise? What should the student have done?

Answer

Most images found online are copyrighted by default, even without a © symbol. The student’s use without permission is copyright infringement even if they did not charge money. What the student should have done: (1) Check the image’s license (Creative Commons, stock photo terms, public domain). (2) Search specifically for Creative Commons licensed images (Google Images → Usage Rights filter, Flickr, Unsplash, Wikimedia Commons). (3) If no license is clear, assume it is fully copyrighted and seek permission.

Creative Commons Licenses

Creative Commons — BY Attribution

Must credit the creator

CC BY: most permissive CC license
Can use, modify, and distribute
Must attribute the original creator
Can be used commercially
Example: most Wikipedia content

Creative Commons — NC (Non-Commercial)

Cannot use for profit

CC BY-NC: use and share freely
Cannot use for commercial purposes
Personal projects and education OK
Cannot sell products using the work
Example: many educational resources

CC SA (Share-Alike)

Derivatives must use same license

If you remix, the new work must also be CC SA
Ensures the ‘open’ chain continues
Called ‘copyleft’ by analogy
Similar to GPL in software
Example: Wikipedia uses CC BY-SA

CC ND (No Derivatives)

Cannot modify the work

Can share as-is without modification
Cannot remix, edit, or build upon
Photography often uses ND
Protects artistic integrity
Most restrictive Creative Commons license

Open Source Software

Scenario — Open Source vs. Proprietary

A developer wants to use Linux (open source) as the OS for their server and Microsoft Windows (proprietary) for workstations. Another team wants to build a product using the open-source Linux kernel.

What rights do they have in each scenario? What obligations might apply?

Answer

With Linux: the source code is public; they can view, modify, and distribute it. Linux uses the GPL license, which requires that modifications must also be released as open source — this ‘share-alike’ provision means if they build a Linux-based product and distribute it, they must release their modifications. With Windows: it is proprietary software. They can use it per the license agreement but cannot view, copy, or modify the source code. Companies like Google (Android) and Meta built products on open-source foundations, contributing changes back to the community.

Common Exam Pitfalls

Copyright is automatic — no © symbol or registration needed

Any original creative work is automatically copyrighted the moment it is created. Absence of a copyright notice does not mean a work is free to use.

Creative Commons is NOT the same as public domain

Creative Commons licenses have conditions (attribution, non-commercial, share-alike, no-derivatives). Public domain has no conditions — anyone can use it any way.

Open source does NOT mean free of cost

Open source means the source code is available to view, modify, and distribute. Some open source software costs money; some free software is closed source. ‘Free’ and ‘open source’ are independent dimensions.

Fair use is limited and often misunderstood

Using copyrighted material in education, commentary, or parody may qualify as fair use, but this is not a blanket exemption. Fair use is evaluated case-by-case and is not the same as having permission.

Check for Understanding

1. A student creates an original drawing. They do not register it or add a copyright symbol. Is it copyrighted?

No — copyright requires registration.
No — copyright requires the © symbol.
Yes — copyright is automatic upon creation of an original work.
Only if the student is an adult.

2. A Creative Commons BY-NC license allows:

Any use without restriction.
Free use with attribution, but not for commercial purposes.
Commercial use only.
Use only with the creator’s explicit permission for each instance.

BY = attribute the creator. NC = non-commercial use only.

3. Open source software is best defined as:

Software that is always free of charge.
Software whose source code is publicly available to view, modify, and distribute.
Software with no copyright restrictions.
Software that runs in a web browser.

Open source = source code is public and modifiable. It may or may not be free of charge.

4. Consider: I. Copyright protects original works automatically. II. Creative Commons licenses require users to place no conditions on use. III. Public domain works can be used freely without permission or attribution.

I and III only
I only
I, II, and III
II and III only

I is correct. III is correct. II is false — Creative Commons licenses DO have conditions (BY, NC, SA, ND).

5. A developer builds a product using open-source code licensed under GPL (which requires derivatives to also be open-source). They distribute the product. What are they required to do?

Pay a licensing fee to the open-source project.
Release the source code of their modifications under the same open-source license.
Display the GPL logo in their product.
Nothing — GPL software can be used freely without conditions.

GPL is a share-alike license. Distributing a derivative requires releasing the modifications as open source under GPL.

6. A student uses a photo with a CC BY-SA license in their school newspaper. They do not credit the photographer. This is:

Acceptable — CC licenses allow free use in education.
A violation of the CC BY condition requiring attribution.
Acceptable because the newspaper is not commercial.
Fine as long as the photo is not modified.

BY means attribution is required. Failing to credit the photographer violates the license conditions.

7. Which of the following is in the public domain?

A poem written in 2020.
A government-funded NASA photo (US federal government works are public domain).
A song released in 1980.
An open-source software project.

US federal government works are explicitly placed in the public domain. Copyright eventually expires for old works, but 1980 is not long enough yet. Open source software is still copyrighted — it just has a permissive license.

8. A company wants to use Wikipedia content in a commercial product. Wikipedia uses CC BY-SA. What must they do?

Pay Wikipedia for commercial use rights.
Attribute Wikipedia/the authors AND release any derivative work under CC BY-SA.
Nothing — Wikipedia content is public domain.
Request written permission for each article used.

CC BY-SA: attribute the source (BY) and release derivatives under the same license (SA). This applies even for commercial use.

9. A music producer releases a song under CC BY-ND. Another musician wants to use samples from it in a remix. Is this allowed?

Yes — Creative Commons always allows remixing.
No — ND (No Derivatives) prohibits creating remixes or adaptations.
Yes, but only for non-commercial remixes.
Yes, as long as the original song is attributed.

ND = No Derivatives. Remixes and adaptations are not permitted under ND licenses.

10. Why do open-source licenses like GPL include share-alike requirements?

To prevent commercial companies from using open-source code.
To ensure that improvements to open-source code remain available to the community.
To make all software eventually free of charge.
To comply with international copyright treaties.

Share-alike ensures that the open-source ecosystem grows: when developers improve open code and distribute it, those improvements must also be open, benefiting the broader community.

How the AP Exam Tests This

Identify whether a described use of copyrighted or licensed material is permissible
Determine which Creative Commons license conditions (BY, NC, SA, ND) apply to a scenario
Distinguish between copyright, Creative Commons, open source, and public domain
I/II/III: which statements about intellectual property are correct
Identify a violation of a specific license condition

FAQ

Does fair use mean I can use any copyrighted work for school projects?

Not automatically. Fair use is evaluated on four factors: purpose (educational = more likely), nature of the work, amount used, and market impact. Educational use is a factor, not a blanket exemption. Short excerpts for commentary or criticism are more clearly fair use than reproducing entire works.

What happens if I violate a Creative Commons license?

Your rights under the CC license are terminated. You would then need a separate license from the copyright holder, or face copyright infringement claims. Most CC violations are handled informally (a request to credit or remove), but legal action is possible.
