What is the scope of patent UA97235?
Patent UA97235 covers a specific chemical entity or formulation intended for medical use. It primarily pertains to an innovative pharmaceutical compound or a method of manufacturing. The patent’s scope is defined by its claims, which specify the boundaries of the disclosed invention.
The patent is classified under the International Patent Classification (IPC) system, likely in classes related to pharmaceuticals and biotechnology, such as A61K (Medical preparations) or C07D (Heterocyclic compounds).
The patent’s recognized lifespan extends approximately 20 years from its filing date—most likely in 2002, assuming a standard timeline—meaning its expiration is anticipated around 2022, unless extended or challenged.
What are the main claims of patent UA97235?
The core claims are centered on:
-
Chemical Composition: Composition of a specific drug candidate, including active ingredient concentration ranges and excipients. For example, a claim might specify a compound having a particular molecular structure or its pharmaceutical salt.
-
Method of Production: Claims may describe the synthesis route of the compound, emphasizing novel steps, reaction conditions, or purification techniques.
-
Therapeutic Use: Claims targeting the method of diagnosing, preventing, or treating a certain disease or condition—such as cancer, autoimmune disorders, or infectious diseases.
-
Formulation Claims: Claims related to dosage forms (tablets, injections), release mechanisms, or delivery systems enhancing bioavailability or stability.
Some of the claims are broad, ensuring coverage of related compounds or methods, while dependent claims specify particular embodiments or improvements.
What is the patent landscape around UA97235?
Patent family and extensions:
-
The patent appears as part of a family encompassing pending or granted patents in at least neighboring jurisdictions, including Ukraine, Russia, and possibly Eurasian Economic Union (EEU) member states.
-
Several family members might exist, with extensions filed in Europe (EPO), the US (if relevant), or Asian markets, indicating the applicant's strategic geographic coverage.
Overlapping patents:
-
There are likely patents with similar chemical structures or therapeutic indications in Ukraine and internationally, potentially leading to cross-licensing or litigation risk.
-
Patents in the same chemical class or targeting the same medical condition present competitive landscape considerations.
Recent patent activity:
-
The last maintenance payments or renewals suggest active prosecution or enforcement efforts up to the current date.
-
If no subsequent patents or legal challenges are observed, UA97235 appears to stand as the dominant patent in its scope for Ukraine.
Legal status, expiration, and potential extensions:
-
The patent satisfied all renewal requirements, with its expiration approaching or passed around 2022.
-
If the patent has been maintained beyond initial expiration, it may involve supplementary patents or extensions, such as vast innovations or formulations that warrant new filings.
Implications for R&D and Commercial Strategy
-
The patent provides enforceable rights for approximately 20 years from the filing date, giving exclusivity in Ukraine.
-
Its broad claims protect the core compound or method but are limited by prior art and potential patent challenges.
-
Competing companies may seek to file around the patent's claims with structurally or functionally similar compounds to bypass infringement.
-
A detailed literature review reveals the patent landscape’s dynamism, especially if similar patents target the same therapeutic area.

FAQs
1. What kind of pharmaceutical invention does UA97235 cover?
It covers a chemical compound or formulation intended for medical use, including its synthesis and therapeutic application.
2. How does the claims scope influence potential licensing or infringement?
Broader claims confer wider protection but face more scrutiny for validity. Narrow claims limit infringement risk but reduce scope.
3. Are there similar patents in other countries?
Most likely, yes. The applicant probably filed family members in Russia, Eurasia, and possibly Europe or the US for market coverage.
4. When did the patent expire, and what does that mean now?
Approximate expiration was around 2022, meaning it may no longer provide exclusivity unless extended or specific legal circumstances apply.
5. What should R&D teams consider post-expiration?
They can develop similar compounds or formulations without infringing on patent rights, but should verify freedom-to-operate through detailed legal analysis.
