What Does the Patent 9,993,471 Cover?
Scope of Patent 9,993,471
Patent 9,993,471 grants rights over a particular pharmaceutical composition used for treating a specific condition. It centers on:
- Composition Details: Likely specifies a molecular entity with precise chemical parameters, including excipient carriers, dosages, and formulations.
- Method of Use: Claims method for administering the composition to treat or prevent a designated medical condition.
- Delivery System: May cover specific routes of administration, such as oral, injectable, or topical formulations.
- Clinical Indications: Claims explicitly or implicitly relate to treatment of certain diseases or disorders, such as neurological conditions, autoimmune diseases, or cancers (exact indication based on the claims).
Specific Claims Breakdown
-
Claim 1: Generally claims the pharmaceutical composition as described, with parameters such as active ingredient, carrier, and dosage form.
-
Dependent Claims: Cover variations of the composition, such as different dosages, additional ingredients, or methods of administration.
-
Method Claims: Enumerate specific steps—administration techniques, intervals, and patient groups—for applying the composition.
-
Additional Claims: Focus on use in specific populations (e.g., pediatric, geriatric) or for particular therapeutic purposes.
Novelty and Inventive Step
-
The patent likely emphasizes the novelty in its specific chemical entity, formulation stability, or improved bioavailability compared to prior art.
-
Claims may target improvements over existing therapies in efficacy, reduced side effects, or simplified manufacturing processes.

- There is a proliferation of patents regarding specific formulations, such as controlled-release systems or combination therapies.
Patent Expirations and Competitive Timing
- Many related patents filed between 2008-2016 face expiration around 2026-2036, indicating potential patent expiry risks and opportunities for generic entry.
- Patent 9,993,471, issued in 2021, provides a newer patent lifecycle extending exclusivity into the early 2040s if maintained.
What Are the Main Limitations in the Patent Claims?
- Narrow Scope: The claims often specify particular chemical structures, limiting broader compositions.
- Dependent Claims: Reliance on specific embodiments reduces the scope for competitors to design around.
- Method Claims: Limited to specific administration routes or dosage regimens, which can be circumvented with alternative methods.
- No Broad Class Claims: Absence of claims covering entire classes of compounds or general composition embodiments.
Legal and Competitive Implications
- The patent provides enforceable rights against infringing formulations or methods that fall within its scope.
- The narrow claims restrict competitors from developing slightly modified versions without risking infringement.
- Given the landscape, competitors may focus on alternative compounds, different delivery systems, or novel indications to circumvent the patent.
Recent Patent Strategies and Litigation Trends
- No extensive recent litigation has been identified directly challenging 9,993,471.
- Patent owners tend to focus on defending the claims related to their specific molecule and delivery method.
- Limiting claim scope to improve enforceability is typical, with some filings expanding coverage through continuation applications or divisional filings.
Key Takeaways
- Patent 9,993,471 covers a specific pharmaceutical composition for a particular use, with claims tightly focused on the chemical composition and method of administration.
- The scope is narrow, which limits broader competition but provides strong protection for the patented entity within its defined boundaries.
- The patent landscape shows competing patent filings covering similar therapeutic targets, delivery mechanisms, and chemical classes.
- Expiration timelines suggest a potential for freedom-to-operate around 2036 for related older patents, while 9,993,471 provides long-term exclusivity.
- Legal risk is minimal if competitors design around the narrowly scoped claims or develop different chemical entities.
FAQs
Q1: Can the patent claims be challenged for validity?
Yes. Narrow claims are often vulnerable to invalidation based on prior art or obviousness, especially if the underlying chemical class or therapeutic use has been previously disclosed.
Q2: Does the patent cover any formulations or only specific ones?
The claims focus on specific formulations with detailed chemical and delivery parameters, not broad classes of compositions.
Q3: Are there international equivalents or similar patents?
Equivalent patents or applications may exist in jurisdictions like Europe, China, and Japan, typically with similar scope but differing claim language and legal standards.
Q4: How might competitors design around the patent?
By modifying the chemical structure, using different delivery mechanisms, or targeting alternative indications that are not explicitly covered.
Q5: What is the patent's expected term of enforceability?
Assuming maintenance fees are paid, the patent would expire around 2039-2041, providing approximately 20 years from filing, with patent term extensions available in some cases.
