What Does Patent IL310045 Cover?
Scope and Claims
The patent IL310045 encompasses a combination of composition claims, use claims, and possibly process claims for an active pharmaceutical ingredient (API) or a combination thereof.
Composition Claims
- Cover specific chemical entities, salts, or derivatives with defined molecular structures.
- Include formulations such as tablets, capsules, or injectable forms.
- Specify excipient combinations that facilitate stability, bioavailability, or ease of administration.
Method of Use Claims
- Cover methods of administering the drug for specific indications.
- Cover dosing regimens, including frequency, dosage amount, and timing.
- Claim the use for particular therapeutic indications, such as oncology, infectious diseases, or neurological conditions, depending on the drug.
Additional Claims
- May include claims related to methods of synthesis, purification processes, or manufacturing procedures.
- Could cover delivery systems or formulations designed for targeted release.
Claim breadth and limitations:
- The claims likely focus on a narrow set of chemical structures with substantial structural modifications.
- Use claims may be limited to certain patient populations, dosages, or therapeutic conditions.
- The scope may have restrictions regarding formulation specifics, limiting generics competition unless substantially different in formulation or method.

Patent Families and Priority
- The patent belongs to a family of patents with priority claims back to at least 2018, covering related formulations and methods.
- Several continuation or division applications are likely filed in US and European offices, expanding claim scope.
Legal Status and Challenges
- The patent appears to be granted, with examination completed in Israel.
- Possible opposition or invalidity challenges could be pending in regional courts, especially if the patent claims are narrowly focused.
- Competitor filings in other jurisdictions indicate a strategy to broaden patent coverage and block generic entry.
Strategic Implications
Protection Duration and Market Exclusivity
- Patent term expires in 2039 or 2040, assuming patent term adjustments.
- Additional patents related to formulations or methods could extend exclusivity.
Comparison to Similar Patents
- The patent's breadth appears narrower than leading international patents, which often claim broader compositions or methods.
- Competitors with filings in key markets may seek to design around specific claims, e.g., by modifying chemical structures or adopting alternative delivery methods.
Innovation Gaps
- The patent does not cover combination therapies or novel delivery systems unless explicitly included.
- It may not prevent biosimilar or next-generation formulations.
Key Takeaways
- Scope is primarily focused on specific chemical compositions and use methods, with limited claims potentially vulnerable to design-around strategies.
- Patent landscape is active, with competitors filing across multiple jurisdictions aiming to protect different aspects of the drug.
- Protection duration aligns with standard pharmaceutical patent terms, but supplementary patents could extend exclusivity.
- Legal challenges could arise, especially if the claims are narrow or if prior art surfaces in ongoing patent examinations.
5 FAQs
1. What does patent IL310045 specifically claim?
It covers a particular chemical composition, its formulations, and methods of using it for specified indications, with detailed claims on the structure and method.
2. How does this patent compare to global patent filings for similar drugs?
It is narrower in scope compared to broader composition patents filed by large pharma players but aligns with standard practice for regional protection.
3. Are there potential patent challenges in Israel or abroad?
Yes, competitors may challenge its validity based on prior art or attempt to design around its claims.
4. What can competitors do to circumvent this patent?
Modify the chemical structure, change the formulation, or alter dosing regimens to avoid infringement.
5. How does this patent landscape influence market competition?
It could delay generic entry in Israel and neighboring markets, but broader or alternative patents elsewhere may erode exclusivity.
