Summary
Patent NO2498610, titled "Treatment of neurodegenerative diseases," was granted in Norway. Its scope centers on specific compositions, methods, and uses related to treating neurodegenerative conditions, particularly Alzheimer’s disease and Parkinson’s disease. The patent claims are designed to cover novel compounds and therapeutic methods involving these compounds. The patent landscape includes similar patents with overlapping claims, especially in the areas of pharmaceutical compositions targeting neurodegeneration.
Patent Scope and Claims
Key Claim Categories
- Compound Claims: Cover novel chemical entities with potential neuroprotective properties.
- Method Claims: Encompass methods for diagnosing, preventing, or treating neurodegenerative diseases using specific compounds.
- Use Claims: Cover the application of the compounds for treating Alzheimer’s and Parkinson’s diseases.
Specific Claim Analysis

Summary |
Distinct Features |
Limitations |
| Compound Claims |
Claim to specific chemical structures, such as derivatives of a certain scaffold. |
Structural features include substitutions at particular positions, presence of functional groups. |
Restricted to compounds with defined stereochemistry and molecular weight ranges. |
| Method Claims |
Claims for administering the compound to a patient with neurodegenerative symptoms. |
Dose ranges, administration routes (oral, injectable), and treatment durations. |
Specific to use with compounds defined in the patent. |
| Use Claims |
Broader claims covering the use of the compound for neurological conditions. |
Disease-specific applications, particularly targeting Alzheimer’s and Parkinson’s. |
May face validity challenges if prior art discloses similar use. |
Claim Breadth and Novelty
- The compound claims focus on derivatives not previously disclosed in prior patents.
- The method claims incorporate specific dosing regimens that may differentiate this patent from prior art.
- Use claims adopt a “second medical use” format, typical in pharmaceutical patents.
Claim Limitations and Potential Challenges
- Overlap with existing patents in neurodegenerative agents could narrow enforceability.
- The scope depends heavily on the novelty of the specific compound structures and treatment methods.
- Prior art references may challenge the scope if similar compounds or uses are documented beforehand.

FAQs
1. What is the primary innovation claimed by NO2498610?
It claims specific chemical derivatives with neuroprotective properties and methods for treating neurodegenerative diseases using those derivatives.
2. How does the patent differ from prior art?
It introduces novel structural modifications to known compounds and specifies treatment regimens that are not disclosed in earlier patents.
3. Is the scope broad or narrow?
The scope is medium; compound claims are specific, but use claims are broader, covering various neurodegenerative conditions.
4. Can third parties design around this patent?
Yes, by developing compounds with different structural features or alternative treatment methods not covered in the claims.
5. What are the risks of patent invalidation?
Prior art disclosures of similar compounds or uses could negate novelty or inventive step, especially if similar derivatives are documented.
