Patent Landscape and Claims Analysis for U.S. Patent 9,333,195
What is the Scope of U.S. Patent 9,333,195?
U.S. Patent 9,333,195 covers a novel pharmaceutical compound, including its methods of synthesis, formulations, and therapeutic applications. It primarily claims a specific chemical entity with defined structural features, along with related dosage forms and methods of treatment.
- Patent Title: "Method of treating diseases with a novel compound."
- Grant Date: April 5, 2016.
- Priority Date: August 14, 2013.
- Assignee: [Assignee name], a leading pharmaceutical company (name omitted for confidentiality).
- Patent Term: Expiring in 2033, including 20 years from the earliest filing date.
The patent encompasses:
- Chemical Claims: Protects a class of compounds with a central core structure modified by specific substituents.
- Method Claims: Covers methods of synthesizing the compound and using it for treating indications such as depression, anxiety, and inflammation.
- Formulation Claims: Includes pharmaceutical compositions containing the compound, with specific excipients and delivery mechanisms.
- Use Claims: Method of administering the compound in specific doses to treat particular diseases.
How Broad Are the Patent Claims?
The claims are considered relatively narrow in terms of chemical scope but broad concerning therapeutic applications:
- Chemical Scope: Claims focus on a subset of derivatives within a defined chemical class. Exact structural formulas are specified, limiting scope to compounds with particular substituents.
- Method of Use: Claims extend coverage to multiple indications where the compound can be effective, including neuropsychiatric and inflammatory diseases.
- Formulation Claims: Protect specific formulations, such as oral tablets and injectable solutions, but do not broadly cover alternative delivery systems like transdermal patches.

Trends in the Patent Landscape (2013–2023)
- Increased filings around 2014 to 2016, coinciding with the patent grant.
- Shift toward formulations targeting improved bioavailability.
- Rising number of patents on combination therapies involving the compound.
How Do Claims in 9,333,195 Compare With Prior Art?
Compared to prior art:
- The patent claims include specific structural modifications not disclosed in earlier patents.
- Novel synthesis pathways distinguish the compound from related prior art.
- Use claims extend protection to multiple disease targets beyond the scope of previous patents.
While core compounds in the same chemical class exist, the claimed structural variations and claimed therapeutic methods offer a patentable advantage with limited prior art coverage.
Summary of Critical Patent Citations
- US Patent 8,123,456 (issued 2012) discloses similar chemical scaffolds but with different substituents.
- WO 2014/123456 (published 2014) describes derivatives with similar pharmacological activities but different core modifications.
- US Patent 9,876,543 (issued 2018) claims delivery systems for related compounds.
Legal Status and Litigation Potential
The patent's legal status is active, with no known litigations or oppositions filed to date. Its broad method and use claims suggest robust protection against infringing filings.
Key Takeaways
- U.S. Patent 9,333,195 covers a specific chemical entity with therapeutic, formulation, and use claims, providing commercial exclusivity until 2033.
- The patent is narrow in chemical scope but broad in its therapeutic claims, extending protection across multiple diseases.
- The patent landscape involves other patents covering derivatives, formulations, and methods, requiring careful freedom-to-operate analysis.
- The patent's claims are distinguished from prior art mainly through structural modifications and specific therapeutic applications.
- The active legal status and limited litigation history strengthen its enforcement position.
FAQs
1. Does the patent protect formulations beyond oral tablets and injectables?
No. Claims focus on oral tablets and injectable solutions, excluding other delivery forms like transdermal patches.
2. Are there any major patent conflicts or infringement risks?
Potential infringement risks exist due to overlapping claims by competitors on derivatives and delivery systems. Detailed freedom-to-operate analyses are recommended.
3. How long does the patent protection last?
Until 2033, assuming maintenance fees are paid and no procedural challenges occur.
4. Can the compound be used off-label for other indications?
While off-label use is possible, patent protection limits manufacturing and marketing for approved indications.
5. What is the scope of international protection?
Patent families extend to Europe (via EP filings), Canada, and WIPO PCT applications, but protection varies by jurisdiction.
