Study Notes

Introduction to Intellectual Property Rights

Intellectual Property Rights (IPR) protect creations of the mind, including inventions, designs, and artistic works.
Key types of IPR include Patents, Confidential Information/Know-How, Copyright, and Trademarks.

Types of IPR

Patents: Must be novel, inventive, and industrially applicable. They are public documents.
Confidential Information/Know-How: Encompasses ideas and information that are kept private.
Copyright: Protects texts, graphics, software, databases, art, and music.

Importance of Patents in Drug Discovery

Patents prevent others from using the patented technology without permission.
The patent term is 20 years from the application date, allowing for market exclusivity.
After 20 years, patents expire, necessitating strategic filing just before product development stages.
Pharmaceutical companies aim for at least 7 years of patent life post-approval.

Patent Process

Initial filing leads to an international application and an examination process lasting 2-5 years.
Patent applications must demonstrate novelty, inventive steps, and industrial applicability.

Criteria for Patents

Novelty: Invention must be new at the Priority Date and not publicly known.
Inventive Step: Must not be obvious to a person skilled in the art at the Priority Date.
Industrial Application: The patent must be applicable to an industry.

Anatomy of a Patent Application

Key components include inventors’ names, title, methods, results, and claims defining the technology's legal scope.
Comprehensive disclosure is required to fulfill patent application criteria.

Challenges to Patents

Patents may be challenged due to claims of infringement, vague or dubious claims, or the use of existing technology.
Broad initial claims are often narrowed down during the patent examination process.

Copyright: Can protect patient information leaflets and companion aids.
Trademark: Represents a brand or product associated with the drug.
Registered Designs: Covers designs related to delivery devices, like inhalers.

Legal Aspects and Considerations

Companies can pursue Non-Disclosure Agreements (NDAs) to safeguard confidential information during the patenting process.
The ability to prove the uniqueness and inventive step of an invention is crucial for patent validity and protection.

Patent Portfolio Management

A strong patent portfolio includes coverage for the active compound, its analogues, methods of manufacture, and formulations.
The patent strategy should encompass both primary and secondary uses to maximize commercial advantages.

Relevant Case Study

Sildenafil serves as an example of a drug with a second medical use patent, illustrating the strategic filing of patents in the pharmaceutical industry.

Summary of Patent Filing in the UK and US

In the UK, patents are awarded on a "first to file" basis, while in the US, it's "first to invent".
The inventive step is evaluated through established tests to determine whether claims are valid based on industry standards.
