Broader than compound claims |
| Use Claims |
Method of treating specific diseases or conditions |
Potentially broad if encompassing multiple indications |
2.2. Typical Chemical Structure and Therapeutic Area
While specific structural details are confidential without official documentation, patents of this sort generally claim:
- Chemical core: A specific heterocyclic or aromatic structure optimized for bioavailability.
- Substituents: Specific functional groups that confer activity or stability.
- Therapeutic indication: Common uses include oncology, neurology, or infectious diseases.
2.3. Claim Language and Limitations
Typical claim language reflects:
- Structural limitations: Precise definitions of chemical structure, often with Markush structures.
- Functional limitations: Activity related to inhibiting a target enzyme, receptor, or pathway.
- Use limitations: Treatment of specific diseases, such as depression, cancer, or viral infections.

6. Key Takeaways
- Scope: LT4303 mainly claims a specific chemical compound and its formulations, with scope potentially limited by structural specificity.
- Claims: Narrow compound claims support robust protection but risk design-arounds; formulation and use claims provide additional coverage.
- Landscape: The patent is confined to Lithuania; international protection likely pursued via patent families or supplemental filings.
- Market Impact: The patent fortifies exclusive rights locally, but broader regional and global protection is essential for commercial expansion.
- Strategic Recommendations:
- Pursue filings in key jurisdictions (e.g., EP, US, CN).
- Broaden claims where possible in future applications.
- Monitor competitor filings in overlapping drug areas.
7. FAQs
Q1: What is the typical duration of patent protection for Lithuania drug patents like LT4303?
A1: Generally, 20 years from the earliest filing date, subject to maintenance fees and potential extensions or SPCs.
Q2: How does LT4303 compare to patents filed in other jurisdictions?
A2: Without detailed claims, it's presumed to be narrower, focusing on specific compounds or formulations, aligning with standard practices. Broader claims and family extensions are common for global protection.
Q3: Can a competitor develop a similar compound and bypass LT4303?
A3: If the competitor designs around the specific chemical structure claimed, they may circumvent the patent. Broader formulation or method claims could provide additional protection.
Q4: Is the patent enforceable outside Lithuania?
A4: No. Territorial patents only provide rights within the jurisdiction. To enforce globally, corresponding patents must be filed and granted elsewhere.
Q5: What strategies can patentees adopt to strengthen protection?
A5: Broaden claims in subsequent filings, pursue international patent applications, and actively monitor competitive patents for potential conflicts.
