A patent is a statutory exclusive right granted for a qualifying invention in return for public disclosure of the invention.
It allows the patentee to prevent unauthorized commercial exploitation of the patented invention
within the territorial and time limits prescribed by law. A patent does not automatically give
permission to use every aspect of an invention; it primarily provides a right to exclude others
from specified unauthorized acts.

The patent system is based on an exchange: the inventor discloses the invention to society,
and the law grants limited exclusive rights if all patentability conditions are satisfied.
2. Historical Development of Patent Law 14 Marks
Early Privileges
Early patent systems developed from privileges granted by rulers to artisans, traders and inventors
for introducing new techniques or industries.
Modern Patent Concept
The system gradually shifted from royal privilege to a statutory right based on objective conditions,
public disclosure, examination and limited duration.
International Development
International trade created the need for priority rules, common filing principles and cooperation
between national patent offices.
Present Importance
Modern patent systems support technological research, commercial investment, licensing,
technology transfer and publication of technical knowledge.
3. Objectives of Patent Protection 7 Marks
Encourage technical innovation.
Reward inventors for research and investment.
Promote public disclosure of inventions.
Facilitate commercialization and licensing.
Support industrial and economic development.
Create an organized body of technical knowledge.
