Copyright and Copyleft are distinct concepts that fall under the umbrella of intellectual property rights.

Copyright is a legal concept that provides exclusive rights to creators, while Copyleft is a licensing method that encourages the unrestricted sharing, modification, and utilisation of creative works.

The fundamental difference lies in the permissions and restrictions associated with each concept.

Copyright restricts the unauthorised use and reproduction of protected works, whereas Copyleft allows for the freedom to copy, modify, and distribute works while ensuring that the same freedoms are preserved for subsequent users.

Understanding these differences is crucial for navigating the complex landscape of intellectual property rights and determining the appropriate licensing approach for creative works.

What is Copyright?

Copyright is a legal concept that grants exclusive rights to the creators or authors of original works, protecting their intellectual property.

Creators are granted the power to regulate the usage, duplication, distribution, presentation, and modification of their work through this.


Imagine you have just finished penning a captivating novel.

With copyright protection, you gain exclusive rights to control the use and distribution of your literary masterpiece.

The statement asserts that the book is protected by exclusive rights, and any reproduction, adaptation, or publication requires prior consent.

A publishing house has expressed interest in your novel and extended a publishing offer.

The contract includes provisions for printing and distributing physical copies of the book within a specified timeframe.

In return, you receive royalties from the sales, ensuring you are compensated for your creativity and hard work.

Without copyright, anyone could freely reproduce your book, claim it as their own, or profit from it without giving you credit.

It safeguards your intellectual property, empowering you to protect your literary creation and reap the rewards of your literary success.

Copyleft is a method that ensures software remains free and open-source, granting freedom to users to use, modify, and distribute the program and its subsequent versions.

Unlike traditional copyright, which restricts certain uses and modifications, copyleft aims to preserve the software’s essential freedoms.

The concept of copyleft is achieved by attaching a license, such as the GNU General Public License (GPL), to the software.

This license mandates that any modifications or extensions made to the original program must also be distributed under the same copyleft license.

This ensures that the software and its derivatives remain freely accessible to all users, preventing them from being converted into proprietary software.

Key Features of Copyleft

Copyleft, derived from the open-source movement, is characterised by several key features that promote collaboration and the free sharing of software:

  1. Freedom to Sell and Redistribute: Copyleft licenses do not impose restrictions on selling or redistributing the software. Users have the freedom to distribute the software to others without limitations.
  2. Allowance for Modified and Derivative Works: Copyleft licenses enable users to create modified or derivative works based on the original software. These modifications can be freely distributed under the same copyleft license terms.
  3. Consistent License Terms: Copyleft ensures that all parties who receive the software are subject to the same license terms. This requirement maintains the integrity of the copyleft license and ensures equal rights for all users.
  4. Availability of Source Code: Copyleft licenses mandate that the source code of the software be made available to users. This facilitates further development and encourages transparency within the software community.
  5. Recognition of Contributors: Copyleft licenses emphasise acknowledging the contributions of each author to the software. This fosters a collaborative environment and recognises the collective effort behind the project.
  6. No Warranties: Copyleft licenses typically disclaim any warranties regarding the performance of the software or the infringement of intellectual property rights. Users are responsible for using the software at their own risk.

By incorporating these features, copyleft licenses aim to promote a culture of openness, collaboration, and the free exchange of knowledge within the software community.

Creative Commons and Copyleft

Copyleft licensing is a type of Creative Commons license.

This system grants creators the ability to share their work without infringing on copyright, as long as users adhere to the specific terms of the license.

Creative Commons licenses come in various types, each with its own set of requirements.

However, one common thread among them is the importance of attribution.

Users are expected to give credit to the original creator and abide by the conditions specified in the license.

One intriguing aspect of copyleft licensing is that it is irrevocable.

When you decide to make your source code or other copyrighted material available to others, you are essentially granting them perpetual access.

This means that as your creation evolves and potentially becomes lucrative, you must carefully consider your intentions and aspirations for the work.

Understanding Creative Commons and Copyleft can help individuals in various fields navigate intellectual property and promote creativity while respecting the rights of others.


The difference between copyright and copyleft lies in their approaches to the rights and freedoms of creators and users.

Copyright places power in the hands of the copyright owner, granting exclusive control over their work and requiring individual permission for any use or modification.

The idea behind copyright is to protect the rights of creators and ensure they are recognised and rewarded for their creations.

On the other hand, copyleft, particularly in relation to software development, embodies a more open and collaborative form of licensing.

It allows users the freedom to use, modify, and distribute the work, provided that they adhere to the licensing agreement and distribute their modifications under the same terms.

This core concept of copyleft emphasises user freedom and the idea that ideas in material form should be freely accessible to all.

One notable aspect of copyleft is that it challenges the traditional legal structure of copyright law by flipping the power dynamics.

The goal is to balance the rights of creators with the freedom of users by promoting the distribution of source code and encouraging collaboration.

Instead of a single person or entity controlling the work, the copyleft concept fosters a community-driven approach.

Ultimately, both copyright and copyleft offer protection under copyright law, but they differ in their approaches to creator protection and the rights granted to users.

While copyright focuses on the exclusive rights of the copyright owner, copyleft seeks to empower users to build upon existing creations and contribute to collective knowledge and innovation.
