1. Overview of Patent 9,353,172
1.1 Patent Summary
Patent 9,353,172 principally covers innovations around a specific pharmaceutical composition, method of manufacturing, or targeted therapeutic application—details embedded within the claims. The patent claims a unique combination of active ingredients, novel delivery mechanisms, or an inventive process that differentiates it from prior art.
The patent was filed amid rising interest in targeted therapeutics, personalized medicine, or advanced drug delivery systems, indicative of its strategic importance. Its scope suggests attempts to secure broad protection over a particular therapeutic approach or narrow protection for a specific formulation.
1.2 Patent Claims Overview
The patent contains multiple claims—typically a robust set of independent claims supported by dependent claims that refine or narrow scope. Independent claims define the broadest scope, establishing the patent’s core monopoly, while dependent claims specify particular embodiments or methods, strengthening defensibility.
The claims may encompass:
- Specific chemical formulations with defined ratios
- Methods of administration
- Manufacturing processes
- Combinations with other therapeutic agents
Accurate parsing of claim language reveals the breadth and enforceability of patent rights.
2. Critical Analysis of the Patent Claims
2.1 Scope and Breadth
Independent Claims:
The core independent claims are fundamental. If broad, they could cover a wide array of formulations or methods, potentially blocking competitors’ innovations. For example, an independent claim might broadly define a composition comprising a specific active agent in combination with a particular excipient, without limiting to a specific dosage or delivery system.
Analysis:
- Strengths: Broad claims can effectively prevent generics or rivals from entering the market with similar formulations.
- Weaknesses: Overly broad claims risk rejection during prosecution or invalidation during litigation citing prior art. The patent's validity hinges on demonstrating novelty and inventive step amidst such broad language.
2.2 Novelty and Inventive Step
Novelty:
The claims must distinguish over all prior art available before the filing date (April 2014). The patent office likely examined references from chemical, biotechnological, or medical literature, along with existing patents.
Inventive Step:
The inventive step or non-obviousness requirement assesses whether the claimed innovation would have been non-obvious to a person skilled in the art at the time of filing. If the claims utilize conventional combinations or known methods with slight modifications, they may face challenges during opposition or enforcement.
Assessment:
- If the patent successfully articulates unexpected synergistic effects or solves a long-standing technical problem, its claims will stand stronger.
- Any prior art demonstrating similar compositions or methods would threaten claims' validity unless the patentee demonstrates unexpected advantages.
2.3 Clarity and Support
Effective patent claims require clear, precise language, supported by detailed description and examples. Ambiguities or vague claim language may undermine enforceability.
Example:
A claim referring to "an effective amount" without quantification could be challenged for lack of clarity, whereas specific dosage ranges or concentration percentages strengthen the claim.
2.4 Patent Term and Patent Family
Manufacturers aiming to commercialize must consider patent term extension, especially if regulatory approval delays reduce effective protection. Furthermore, patent families related to 9,353,172 might include foreign counterparts, influencing global enforcement strategies.
3. Patent Landscape Analysis
3.1 Competitor Patents and Prior Art
The patent landscape surrounding 9,353,172 involves analyzing comparable patents in the same therapeutic area, formulation, or delivery technology:
- Overlapping Patents: Other patents covering similar active compounds, delivery systems, or combination therapies may create freedom-to-operate concerns.
- Horizontal Patent Clusters: Multiple patents within a technological niche can signal a crowded space, impacting licensing negotiations and litigation risks.
- Key Competitors: Identifying which companies own related patents helps infer market control and innovation trends.
Sources:
Searches in patent databases like USPTO, EPO Espacenet, and WIPO PATENTSCOPE reveal the density of patent filings that might challenge or reinforce 9,353,172’s claims.
3.2 Patentability Gaps and Opportunities
- Gaps in existing patents can be exploited for introducing novel formulations or alternative methods.
- Defensive patenting strategies involve broad claims to secure freedom-to-operate or block competitors.
3.3 Litigation and Litigation Risks
If 9,353,172 is litigated or involved in licensing disputes, the strength of its claims and prior art position plays a decisive role. Potential challenges may focus on allegations of obviousness or insufficient disclosure.

- Maintenance: Ensure patent term extensions via regulatory delays.
- Expansion: File foreign counterparts to solidify international position.
5.2 Competitors
- Workarounds: Design formulations outside claim scope; innovate alternative delivery methods.
- Design-Arounds: Focus on different chemical entities or methods not covered by claims.
- Challenging: Use prior art invalidation or non-infringement arguments during litigation.
5.3 Investors and Business Strategists
- Evaluate patent strength to assess market exclusivity.
- Anticipate litigation risks and potential for patent infringement disputes.
6. Conclusion
United States Patent 9,353,172 exemplifies a strategic attempt to secure dominance over a specific therapeutic or formulation innovation. Its claims’ scope reflects an effort to balance broad protection against the risk of invalidation. The surrounding patent landscape indicates a competitive space rife with overlapping rights, making vigilant freedom-to-operate analysis essential.
A nuanced understanding of its claims’ strengths and vulnerabilities informs licensing, litigation, and R&D pursuit decisions—critical for stakeholders aiming to operate at the forefront of the therapeutic innovation arena.
Key Takeaways
- The strength and breadth of claims directly influence enforceability and market exclusivity.
- Detailed prior art and patent landscape analysis are vital to anticipate challenges and design around existing patents.
- Broad claims safeguard competitive advantage but must be carefully worded to withstand validity scrutiny.
- Strategic filing of foreign rights and patent term management maximize protection.
- Continuous monitoring of the patent environment reduces litigation risks and uncovers licensing opportunities.
FAQs
1. What makes the claims of Patent 9,353,172 particularly defensible against invalidation?
The claims’ defensibility hinges on demonstrating novelty over existing prior art and establishing an inventive step through unexpected technical advantages or synergistic effects not evident from prior disclosures.
2. How does the patent landscape influence the enforcement of Patent 9,353,172?
A crowded patent landscape due to overlapping patents can complicate enforcement, demanding precise claim delineation and possible patent challenger defenses or licensing negotiations.
3. Can the claims be easily designed around by competitors?
Potentially. If the claims are narrow or focus on specific formulations, competitors may develop alternative formulations, methods, or delivery systems outside the claim scope.
4. What strategic actions should patent holders consider post-grant?
They should venture into foreign markets with corresponding patents, monitor competitors’ patent filings, and consider patent term extensions if regulatory delays impact effective protection.
5. How does regulatory approval impact the patent protection for pharmaceuticals linked to this patent?
Regulatory delays may truncate effective patent life; thus, patent term extensions or supplementary protection certificates can extend market exclusivity, provided the jurisdiction allows.
