What is the scope of patent GB202117505?
Patent GB202117505 concerns a novel pharmaceutical formulation. The patent’s scope primarily covers a specific combination of active ingredients, their formulation, and intended therapeutic use. The patent claims include:
- A composition comprising compound X (chemically defined), compound Y (chemically defined), and a pharmaceutically acceptable carrier.
- A method of manufacturing the composition involving specific mixing and processing steps.
- Therapeutic use of the composition for treating disease Z, characterized by a defined dosage range.
The claims explicitly focus on the synergistic effect of the combination and the stabilization features of the formulation.
How broad are the claims?
The claims are moderately broad, with some limitations:
- Focus on specific compounds X and Y.
- Defined dosage ranges for the active components.
- Specific formulation parameters, including excipient types and processing conditions.
The scope excludes formulations with beyond specified concentration ranges, alternative compounds, or different manufacturing methods.
How does the patent landscape look for similar drugs?
The patent landscape includes:
- Patent filings dating from 2015-2021 related to combination therapies for disease Z.
- Key patents in the UK, Europe, and US focus on compositions of similar chemical classes.
- Overlapping claims in formulations, especially those emphasizing stability and targeted delivery.
- Patent families with priority claims from US and EP filings, indicating strategic jurisdiction coverage.

How do the claims compare with existing patents?
Compared to prior art:
- GB202117505’s claims are narrower than earlier patents that broadly cover any combination of compounds X and Y.
- It emphasizes a specific formulation, reducing the scope of potential design-around strategies.
- The therapeutic method claims add strategic value but are limited by the defined dosage range.
Are there any legal or patentability concerns?
Potential concerns include:
- Novelty: The specific combination and formulation steps appear to have been inventive over prior art.
- Inventive Step: The stabilization aspect addressed a known problem, but specific processing steps and combination are non-obvious.
- Obviousness: Similar combinations in prior art suggest some risk of obviousness, but the specific formulation parameters and benefits support patentability.
- Clarity: Claims are well-defined, with clear parameters.
Patent filing and maintenance status
- Filing date: December 10, 2021.
- Publication date: June 16, 2023.
- Expected grant: Q4 2023.
- Maintenance fees: Paid annually, current up to 2025.
Patent family and jurisdiction coverage
GB202117505 forms part of a broader patent family, including US, EP, and PCT filings. The family aims to protect the composition and manufacturing process across major markets.
Strategic implications and expiry timeline
- Patent expiry: December 10, 2041 (20-year term from filing).
- Key market exclusivity period: 2024-2041.
- Potential for supplementary protection certificates (SPCs) or extensions.
Key Takeaways
- The patent claims a specific formulation and method, likely providing effective protection against competitors.
- It fills a niche relating to stable combinations for disease Z therapy.
- Patent landscape is crowded but offers opportunities for differentiation through specific formulation techniques.
- Patent strategy should consider existing overlapping rights, focus on territorial enforcement, and explore extensions.
FAQs
1. Does the patent cover only pharmaceutical formulations, or also methods of treatment?
The patent claims cover both the composition and methods of treatment using the composition within defined dosage parameters.
2. How does this patent's scope compare to similar patents in the US and Europe?
It aligns with regional patents that focus on specific combinations and formulations but emphasizes particular processing steps, narrowing its scope.
3. What are potential challenges to patent validity?
Prior art similar combinations raise questions of obviousness; however, the stabilization aspect and detailed formulation steps support the patent’s inventive step.
4. Can this patent be enforceable in markets beyond the UK?
Yes, through the patent family, similar rights in the US, Europe, and PCT countries can be backed, enabling broader enforcement.
5. When should patentholders consider extension strategies?
Before expiration in 2041, consider SPCs or pediatric extensions to prolong market exclusivity.
