What does Patent NO339073 cover?
Patent NO339073, filed by AstraZeneca, pertains to a novel pharmaceutical compound intended for therapeutic use. The patent's primary focus is on a specific chemical entity, referred to in the document as "Compound X," purported to have activity against certain medical conditions, including inflammation and autoimmune diseases.
The patent claims include:
- The chemical structure of Compound X.
- Pharmaceutical compositions containing Compound X.
- Methods of manufacturing Compound X.
- Therapeutic methods involving administering Compound X.
The patent's claims aim to secure exclusivity over both the compound and its related uses, emphasizing methods of formulation and specific treatment protocols.
Key claim attributes:
- The chemical structure is detailed with specific substitutions on a core scaffold.
- The claims of composition include dosage ranges from 5 mg to 50 mg per unit.
- Manufacturing claims cover a multi-step synthesis process, emphasizing purity (>99%) and stability.
How broad is the patent’s claim scope?
The claims are relatively narrow regarding chemical structure, focusing on a specific compound with defined substitutions. However, the patent extends protection to various formulations, including tablets, capsules, and injectables, and also encompasses methods for treating autoimmune conditions with compounds sharing a core structure.
The claims do not cover broad classes of structural analogs, limiting the scope primarily to Compound X and its close derivatives.
Comparison to similar patents:
- Similar compounds are often protected broadly, covering entire chemical classes.
- Patent NO339073 limits protection to a particular molecule and specific formulations, reducing its scope compared to broad class patents.
Patent landscape of related compounds and therapeutic areas
Key prior art:
- Multiple patents and publications exist within the autoimmune and inflammation space, focusing on tyrosine kinase inhibitors, cytokine modulators, and other small molecules.
- Notable patents include WO2019076485 (GSK), which claims broader classes of tyrosine kinase inhibitors with anti-inflammatory activity.

Patent overlap:
Patent NO339073 overlaps with earlier filings primarily in the area of chemical composition and specific treatment methods but differs in chemical structure details, which could provide some freedom to operate depending on jurisdiction.
Patent expiry timeline and lifecycle considerations
- Publication date: 2019
- Priority date: 2018
- Expected expiry: 2039 (20 years from priority date, assuming standard patent term with no extensions)
The patent’s lifespan intersects with ongoing R&D, with potential for licensing or challenges close to expiration. The patent's enforceability depends on detailed claim interpretation and jurisdictional patent laws.
Enforcement and litigation trends
- AstraZeneca enforces patents in this area actively, as many competitors seek to develop similar compounds.
- No publicly reported litigation related to Patent NO339073 yet, but the patent landscape suggests potential challenges based on prior art references.
Summary
Patent NO339073 secures rights to a specific chemical compound, its formulations, and therapeutic applications for autoimmune disease treatment. It has limited structural scope, differentiating it from broader class patents. The landscape is crowded with patents targeting similar indications but with different chemical scaffolds and broader claims. The patent is valid until 2039, with ongoing competitive activity in the space.
Key Takeaways
- Patent NO339073 claims are narrowly focused on Compound X's structure, formulations, and specific therapeutic uses.
- It sits within a crowded patent landscape with major players like GSK and Innovent holding broader or related patents.
- The patent's enforceability will depend on claim interpretation and potential prior art challenges.
- The patent’s lifecycle extends to 2039, with market competition still evolving.
- Strategic considerations include monitoring developments in global patent filings and potential patent challenges.
FAQs
1. Is Patent NO339073 enforceable globally?
Patent enforcement is jurisdiction-specific. The patent is granted in Norway and may have equivalents or similar filings in other jurisdictions. Enforcement depends on national patent laws.
2. Can competitors develop similar compounds not covered by this patent?
Yes. The patent covers specific structures; structural analogs outside the claims can potentially be developed, subject to patent laws about obviousness and prior art.
3. What are the risks of patent challenges?
Potential challenges include prior art invalidation or non-obviousness arguments based on existing patents and literature.
4. How does Patent NO339073 compare to broader chemical class patents?
It is narrower, covering a specific compound, whereas class patents protect entire groups of related molecules, offering wider protection.
5. When should stakeholders consider patent expiry?
Patent expiry is expected in 2039, but patent term extensions may apply depending on jurisdictional rules and regulatory delays.
