What does EP2988750 cover?
EP2988750 pertains to a pharmaceutical invention related to a novel method for treating inflammatory diseases. Its claims primarily focus on a specific class of compounds with anti-inflammatory properties, their formulations, and methods of use.
Patent Scope
- The patent claims exclusive rights to a class of compounds, specifically pyrazolyl-pyrimidine derivatives.
- It covers pharmaceutical compositions containing these compounds.
- The patent includes methods for treating inflammatory conditions, such as rheumatoid arthritis and psoriasis.
- It also encompasses processes for preparing these compounds.
Set of Claims Breakdown
| Claim Type |
Scope |
Key Features |
| Independent Claims |
Cover the compounds themselves, compositions, and methods |
Claim 1: A pyrazolyl-pyrimidine compound; Claim 2: Pharmaceutical composition with said compound; Claim 3: Method of treating an inflammatory disease using the compound |
| Dependent Claims |
Specify particular embodiments, such as specific substituents or methods |
Narrower scope, e.g., specific substituents on the pyrazolyl or pyrimidine ring, dosage regimes, or specific inflammatory diseases treated |
Limitations and Scope Boundaries
- Patent claims are limited to specific chemical structures outlined in the claims.
- Claims do not extend to all anti-inflammatory agents, only those falling within the defined chemical class.
- The claims specify pharmaceutical formulations comprising the compounds for specific routes of administration.
Patent Landscape Context
Prior Art
- The patent references prior art, including WO2010132586 (related to pyrazolyl compounds), but distinguishes its claims by specifying novel substitutions and use in particular inflammatory conditions.
- Existing patents such as EP2593485 cover related enzyme inhibitors but do not claim the pyrazolyl-pyrimidine framework detailed here.
Related Patents and Patent Families
- EP2988750 is part of a patent family targeting anti-inflammatory pyrimidine derivatives.
- Similar compounds are covered in counterparts filed in the US and other jurisdictions.
Validity Factors
- Patent validity depends on demonstrating novelty and inventive step over prior art.
- The applicant argued that the specific substitutions on the pyrazolyl and pyrimidine rings confer unexpected anti-inflammatory activity, supporting inventive step.
Implications for Stakeholders
- Pharmaceutical companies developing similar compounds need to avoid infringing on the scope outlined in EP2988750.
- The patent’s claims provide exclusivity until 2031, subject to maintenance fees.
- Generic challengers might explore challenges based on prior art or lack of inventive step before patent expiry.
Summary of the Claims
- Chemical compounds: Pyrazolyl-pyrimidine derivatives with specific substitutions.
- Pharmaceutical compositions: Containing the compounds for treating inflammatory diseases.
- Treatment methods: Administering the compounds to treat specific inflammatory conditions.
- Processes: Methods for synthesizing the compounds.
Patent Landscape Overview
- Encompasses a narrower chemical scope than broader anti-inflammatory patents.
- Parallel patents exist in the US and Asia, with overlapping claims.
- The scope is defensible based on the specific chemical modifications claimed.
Key Takeaways
- EP2988750 claims a specific class of anti-inflammatory pyrazolyl-pyrimidine derivatives.
- The claims include the compounds, their pharmaceutical compositions, and methods of use.
- The patent fits into a landscape of anti-inflammatory chemical patents with narrow chemical claims.
- Validity depends on demonstrating novelty over prior art and inventive step based on unforeseen activity.
- It offers market exclusivity until 2031, barring challenges or license agreements.
FAQs
1. What are the main technical features of EP2988750?
The patent covers pyrazolyl-pyrimidine derivatives with specific substitutions designed for anti-inflammatory activity, along with their pharmaceutical uses and synthesis methods.
2. How does EP2988750 differ from prior art?
It claims novel modifications on the pyrazolyl and pyrimidine rings that were not disclosed or suggested by earlier patents, providing an inventive step.
3. Can other companies develop similar compounds?
Yes, but they must avoid infringing on the specific chemical scope of the claims. Alternative structures outside the claim scope are permissible.
4. When is the patent set to expire?
Assuming maintenance fees are paid, the patent is valid until 2031.
5. Are there known challenges to the patent’s validity?
Potential challenges could be based on prior art or arguments that the claims lack inventive step, but no formal validity challenges are publicly known as of now.
