— Unit - 2 —
1. Introduction to Intellectual Property (IP)
Intellectual Property refers to creations of the mind: inventions, literary and artistic works, designs, and symbols, names, and images used in commerce. IP law grants the creator exclusive rights to exploit their creation commercially for a specific period of time.
⇒1.1 The Philosophy of IP
IP laws exist as a societal trade-off. They grant a temporary monopoly to the creator as an incentive to invest time and money into research and development. In return, society benefits from the eventual public release and widespread use of the innovation.
Apple's multi-touch gesture algorithm; a new silicon chip architecture.
Copyright
Original expressions of ideas (literary, artistic, software source code).
Life of author + 60 years (in India).
The exact source code of Windows 11; the artwork in a video game.
Trademark
Symbols, names, logos that identify the source of goods.
10 years, indefinitely renewable.
The Google logo; the name 'Bluetooth'; Intel's distinctive audio chime.
Trade Secret
Confidential business information providing a competitive edge.
Indefinite (as long as it remains a secret).
Google's search ranking algorithm; the formula for Coca-Cola.

3. Software: Patent vs. Copyright
The protection of software is legally complex and heavily debated.
⇒3.1 Copyrighting Software
Under the Berne Convention and Indian Copyright Act, software source code is protected automatically as a 'literary work' the moment it is typed. However, copyright only protects the literal expression of the code. If someone writes entirely new code from scratch that achieves the exact same result, it is not a copyright violation.
⇒3.2 Patenting Software
A patent protects the underlying idea or method. To get a software patent, the software must usually be tied to a novel hardware operation (e.g., software that makes a CT scanner render images faster). Pure business logic or mathematical algorithms are generally non-patentable in India (Section 3(k) of the Patents Act), though the US allows broader software patents.

4. Software Licensing Models
A software license is a legal instrument governing the use or redistribution of software. Since software is copyrighted, using it without a license is illegal.
⇒4.1 Proprietary (Closed Source) Licenses
The publisher retains ownership. The user merely buys a 'license to use' the software under strict conditions.
Users cannot view the source code, modify it, or distribute it.
Example: Microsoft Office End User License Agreement (EULA).
⇒4.2 Open Source Licenses
Open Source Initiative (OSI) defines open source not just as 'free to view', but granting the user the right to freely use, modify, and distribute the software. However, Open Source is heavily divided into two camps:

5. Copyleft vs. Permissive Open Source
⇒5.1 Permissive Licenses (MIT, Apache, BSD)
These are highly relaxed. They allow anyone to take the source code, modify it, compile it, and sell it as closed-source proprietary software, as long as they retain the original copyright notice. Companies love permissive licenses because they can use free code in their commercial products without legal risk. (e.g., React JS uses MIT).
⇒5.2 Copyleft / Viral Licenses (GPL)
Designed by Richard Stallman (Free Software Foundation). Copyleft licenses (like the GNU General Public License) have a strict 'viral' condition: If you modify and distribute GPL software, your modified version must also be released under the GPL. You cannot make it closed-source. This ensures the software remains free forever. (e.g., The Linux Kernel).

6. Digital Rights Management (DRM)
Because digital goods (movies, software, MP3s) can be copied perfectly at zero cost, media companies deploy DRM.
DRM uses cryptography and access control technologies to physically restrict how users interact with media they have purchased. Examples include restricting a Kindle book from being read on a non-Amazon device, or preventing a DVD from being ripped to a hard drive.
Ethical Debate: Proponents argue DRM is the only way to ensure artists get paid in the digital age. Detractors argue DRM treats all consumers as criminals, prevents 'Fair Use' (like quoting a snippet for education), and means consumers no longer truly 'own' the media they buy.

7. Unit Summary and Exam Priorities
This unit blends law with computer science. You must be precise with legal terminology.
The Big 4: Never confuse a Patent (inventions) with a Trademark (brands) or Copyright (art/code). Know the durations for each.
Software Protection: Be able to explain why software companies heavily rely on Copyright and Trade Secrets rather than Patents (patents are expensive, take years to get, require full public disclosure of the algorithm, and expire after 20 years).
Open Source: The difference between GPL (viral/copyleft) and MIT (permissive) is the most frequently tested concept in licensing.
