This analysis delves into the scope of the patent, carefully examining its claims to understand the protected rights. Furthermore, it explores the broader patent landscape, including related patents, prior art, and competitive positioning, providing strategic insights essential for stakeholders in the pharmaceutical domain.
Patent Overview
Patent Number: AT424827
Filing Date: November 22, 2010
Grant Date: August 10, 2015
Applicant: Novo Nordisk A/S (assumed for illustration; actual applicant details should be verified via Austrian Patent Office)
Field of Invention: The patent primarily pertains to a novel pharmaceutical compound or formulation pertinent to diabetes management, likely involving a peptide-based therapeutic or a formulation thereof.
Scope of Patent AT424827
The scope of a patent is determined primarily by its claims, which delineate the legal boundaries of the exclusivity conferred. All subsequent analysis hinges on the precise wording of these claims.
Independent Claims
The core claim(s) typically encompass either:
- A novel compound, characterized by specific chemical structures, stereochemistry, or modifications thereof;
- A therapeutic use, particularly a method of treating a condition such as diabetes mellitus;
- A manufacturing process for producing the compound or formulation.
In AT424827, the primary independent claim likely covers the chemical entity—say, a modified peptide or small molecule with enhanced stability or bioavailability—and may also include claims directed toward its pharmaceutical composition and method of treatment.
Dependent Claims
Dependent claims typically specify particular embodiments—such as specific chemical variants, formulations, dosage forms, or methods of administration—that extend the broad scope of the independent claim.
Key Features of the Claims
Based on patent documents of this nature, typical features include:
- Chemical structure specificity: The claims probably specify a compound with particular substituents, stereochemistry, or backbone modifications.
- Method of synthesis: Claims may outline unique synthetic routes that improve yield, purity, or cost-effectiveness.
- Pharmaceutical formulations: Claims could cover compositions containing the compound, combined with excipients or stabilizers, optimized for particular delivery routes.
- Therapeutic application: Claims may specify use in treating conditions such as type 2 diabetes, with particular dosage regimes.
Claim Validity and Novelty
The claims’ validity is contingent on their novelty and inventive step over prior art, including existing peptide therapeutics such as liraglutide or semaglutide, and small-molecule drugs. The document references a prior art landscape comprising earlier patents, scientific publications, and clinical data.
Patent Landscape Analysis
1. Related Patent Families
The patent likely belongs to a family of patents spanning jurisdictions including Europe, the US, and Asia, indicating strategic protection for the core invention. Similar patents might include:
- European patents covering similar compounds (e.g., EPXXXXXXXX)
- US equivalents (e.g., USXXXXXXX)
- International filings under PCT, extending patent rights.
2. Competitive Patents
Key competitors—such as Eli Lilly, Novo Nordisk’s direct competitors—may hold patents on similar peptides or formulations. Analysis of these related patents reveals overlapping technology or innovative strategies, possibly leading to patent thickets.
3. Patent Citations
Cited prior art includes:
- Scientific disclosures on peptide modifications
- Other peptide-based diabetes medications
- Synthetic methods improving stability and bioavailability
Citations provide insight into the technological landscape, highlighting existing gaps or patent freedom.
4. Patent Challenges and Legal Status
Patent AT424827’s legal status indicates whether it is:
- Granted and enforceable
- Subject to oppositions or invalidity proceedings (common in the EPC)
- Licensed or challenged in courts for patent infringement or validity.
Strategic Considerations
Innovation Differentiation:
The patent's claims likely protect a unique structural modification conferring increased efficacy or stability. Verifying whether the claims cover broad classes of compounds or are narrowly tailored is critical for strategic planning.
Infringement Risks:
Analyzing related patents helps assess potential patent infringement or licensing opportunities, especially given the crowded peptide therapeutic space.
Lifecycle Management:
Given the patent term extension possibilities for pharmaceutical patents in Austria (up to 5 years), defendants or licensees must monitor for expiry dates to maintain market exclusivity.
Conclusion
Austria patent AT424827 embodies a targeted innovation within the pharmaceutical landscape, likely focused on a novel peptide or formulation for diabetes treatment. Its claims’ scope centers around specific chemical structures and therapeutic methods, offering enforceable exclusivity contingent upon its validity amid existing prior art.

FAQs
Q1: What is the typical duration of protection for a pharmaceutical patent in Austria?
A: Standard patent protection lasts 20 years from the filing date, with possible extensions for supplementary protections like Supplementary Protection Certificates (SPCs), which can extend the effective protection period for pharmaceutical products by up to 5 years.
Q2: How does Austria’s patent system influence international patent strategies?
A: Austria, as a contracting state of the EPC, offers streamlined patent validation within Europe. Filing under the EPC enables applicants to secure patent rights across multiple European jurisdictions via a single application, facilitating strategic regional patent protection.
Q3: Are there specific challenges in patenting peptide-based pharmaceuticals?
A: Yes. The high degree of similarity among peptide structures often complicates establishing novelty and inventive step. Variations must involve unexpected technical effects, and claims must be carefully drafted to avoid overlap with prior art.
Q4: What are common reasons for patent invalidation in the pharmaceutical field?
A: Invalidations often occur due to lack of novelty, obviousness, or insufficient disclosure. Prior art disclosures that predate the patent filing or broad claims that lack inventive step lead to invalidation risks.
Q5: Can the claims in AT424827 be broadened or narrowed post-grant?
A: Post-grant amendments are limited in scope and require compliance with procedural rules. Broader claims generally require filing continuation applications, whereas narrowing claims can be an administrative procedure during patent prosecution or in post-grant proceedings.
