It is crucial to highlight specific unexpected properties or new therapeutic uses that differentiate the innovation from existing solutions.
Overcoming Patentability Exclusions
Certain jurisdictions have specific exclusions from patentability, especially concerning natural substances or methods of treatment. Innovators need to focus on synthetic methods, novel formulations, or specific non-natural modifications that can be patented.
Additionally, framing the patent claims to cover the application or use of the method rather than the method itself can sometimes circumvent these exclusions.
Handling Biologic Complexity
Anti-cancer drugs, particularly biologics, involve complex biological materials that can be challenging to describe in a patent application. Ensuring that the patent application thoroughly details the biological or chemical properties and processes involved is critical.
This includes having clear, reproducible methods and specific use cases that underscore the uniqueness of the biologic.
Strategic Patent Drafting
Crafting the patent application with strategically structured claims is pivotal. Claims should be broad enough to prevent easy workarounds yet specific enough to clearly define the scope of the innovation.
Including fallback positions in the claims can help in retaining some form of protection even if the broader claims are later invalidated or challenged.
Managing Public Disclosure
Public disclosures before filing can jeopardize patentability. It’s crucial for researchers and companies to manage the flow of information, especially at scientific conferences and in publications.
Establishing strict disclosure policies and considering provisional patent applications before public disclosures are strategic moves that can protect the patentability of a novel anti-cancer drug.
Preparing for Post-Patent Scenarios
Your patent strategy shouldn’t just focus on obtaining and enforcing patents but also on what happens once they expire.
