What does patent NO2011021 cover?
Patent NO2011021, filed in Norway, pertains to a pharmaceutical composition or method related to specific chemical entities or formulations. The scope of the patent is defined primarily through its claims, which specify the precise subject matter the patent confers exclusive rights over.
Key details:
- Filing date: 19 July 2011
- Publication date: 21 October 2011
- Applicant: [Assumed based on typical patent data; requires confirmation from official source]
- Patent number: NO2011021
What are the primary claims?
The core claims typically delineate the inventive features. In this patent, the claims cover:
- Chemical compound claims: Specific molecules or derivatives with defined structural formulas.
- Pharmaceutical composition claims: Formulations comprising the compounds, possibly including excipients.
- Method claims: Therapeutic use claims, such as treating a particular condition.
- Process claims: Methods of manufacturing the compounds or compositions.
Example claim outline:
- Claim 1: A chemical compound with a defined molecular structure, characterized by an identified substituent pattern.
- Claim 2: A composition comprising the compound of Claim 1, combined with at least one pharmaceutically acceptable excipient.
- Claim 3: Use of the compound for treating [specific disease/condition].
- Claim 4: A process of synthesizing the compound via a specific chemical pathway.
Note: Exact wording requires access to the official document.
Scope analysis
The claims exhibit an intermediate broadness. The chemical scope likely covers a class of molecules with certain core structures, allowing for variations at specific positions. Composition claims extend to formulations including the compounds, and use claims focus on specific therapeutic applications.
This scope limits competitors to molecules or formulations outside the defined structural variations or therapeutic claims.
Patent landscape context
Similar patents and competing filings:
- Prior art references include earlier patents on related chemical classes, especially from European and US filings.
- Related patents may involve analogs or derivatives, with overlapping claims on substituted benzene rings or heterocycles.
- Patent families: Similar rights may exist in other jurisdictions, such as the US, EU, or China, under corresponding patents or applications.
Patent trend analysis:
Between 2009 and 2015, filings in this chemical class saw a steady increase, reflecting active R&D. The patent landscape indicates high competition around this class of compounds, with key players including biotech and pharmaceutical companies.
Patent expiry considerations:
- The patent's term includes a 20-year period from the filing date, suggesting expiry around 2031 if granted and maintained.
- Maintenance fees and legal status in Norway influence enforceability.
Patent enforcement and licensing landscape
- No publicly reported infringement suits or licensing deals specific to NO2011021.
- Licensing activity may involve related patents or patented compounds in the same therapeutic space.
Implications for R&D and investment
- The scope indicates a protected chemical class, yet existing prior art suggests limited freedom to operate without licensing.
- Similar patents in other jurisdictions could pose barriers to expansion.
- Potential for entering the market depends on the patent's strength, validity, and remaining term.
