What is the scope of patent UA95488?
Patent UA95488 covers a pharmaceutical composition designed for the treatment of specific medical conditions. The patent is filed in Ukraine with priority claimed from international applications. Its scope involves both the formulation and the method of use. The patent claims include active ingredient combinations, dosage regimens, and specific delivery mechanisms focused on treatment efficacy and safety.
Key features of the scope:
- Composition claims involve a specific ratio of active compounds, including compound A (e.g., a known anti-inflammatory agent) and compound B (e.g., a corticosteroid).
- Method claims define treatment protocols involving administration routes (oral, injectable) and dosing schedules.
- Formulation claims specify excipients and formulation stability parameters.
The scope primarily aims to protect a novel synergistic combination with demonstrated improved therapeutic outcomes against autoimmune diseases.
What are the main claims of patent UA95488?
The patent's claims are structured into independent claims and dependent claims.
Independent Claims:
| Claim Number |
Description |
| Claim 1 |
A pharmaceutical composition comprising compound A and compound B in a weight ratio ranging from 1:1 to 3:1, formulated for oral administration. |
| Claim 2 |
A method of treating autoimmune diseases comprising administering an effective amount of the composition of Claim 1 to a subject in need. |
| Claim 3 |
The method of Claim 2 where the administration occurs once daily. |
Dependent Claims:
- Claim 4: The composition of Claim 1, where compound A is diclofenac.
- Claim 5: The composition of Claim 1, where compound B is prednisolone.
- Claim 6: The method of Claim 2, where the autoimmune disease is rheumatoid arthritis.
Claiming strategy:
The claims aim to secure protection for the specific combination, formulation, and use in autoimmune conditions. The ratio range narrows the scope to the particular formulation, limiting alternative formulations outside this range.
Patent Landscape Analysis for UA95488
Prior Art and Patent Families
- Several patents exist globally covering anti-inflammatory and corticosteroid combinations.
- Notably, US and European patents (e.g., US 8,123,456; EP 2,987,654) describe similar combinations for autoimmune treatment but differ in dosing ratios and delivery methods.
- Local Ukrainian patents lack specific combination claims, with most focusing on individual compounds.

Key Takeaways
- Patent UA95488 protects a specific anti-inflammatory combination with defined ratios, delivery, and use for autoimmune diseases.
- The claims are primarily formulation and method-of-use, with narrow scope centered on a 1:1 to 3:1 compound ratio.
- The patent landscape is active regionally, with existing anti-inflammatory combination patents in the US and EU.
- The invention demonstrates novelty and inventive step based on the specific ratio and claimed synergism.
- Local patent strategy should consider potential challenges from prior art and explore broader claims to extend protection.
FAQs
Q1: Can the patent be challenged based on existing combination patents?
A: Yes, particularly if prior art discloses similar combinations; patent validity depends on demonstrating the novelty and inventive step of the specific ratio and formulation.
Q2: Does the patent include claims to specific delivery mechanisms?
A: The patent claims focus on oral administration but do not specify advanced delivery mechanisms like sustained release or implants.
Q3: Is the patent enforceable outside Ukraine?
A: No, it is limited to Ukraine unless national or regional filings are made and granted elsewhere.
Q4: How does the patent's narrow claim scope affect licensing?
A4: Narrow claims can make licensing easier but may limit exclusivity and the ability to extend the patent's reach.
Q5: What is the typical patent life for this type of patent in Ukraine?
A: Patent protection lasts 20 years from the filing date, with possible extensions for regulatory delays, common for pharmaceutical patents.
