Patent Landscape and Claims Analysis for U.S. Patent 9,855,241
What does U.S. Patent 9,855,241 cover?
U.S. Patent 9,855,241 pertains to a specific pharmaceutical composition and its use, with a focus on a novel drug formulation. It claims methods of treatment for a targeted disease using this composition. The patent covers both the compound itself and related methods of administration.
Summary of the patent claims
The patent contains 15 claims, primarily focusing on:
- The chemical structure of the active pharmaceutical ingredient (API).
- The specific formulation parameters, including excipients and dosage forms.
- Methods for treating the specified condition using the composition.
- Stable formulations with enhanced bioavailability and shelf-life.
Sample Claim Breakdown:
- Claim 1: Defines the core chemical entity with a specific molecular structure.
- Claim 2: Describes a pharmaceutical composition comprising the core API with an excipient.
- Claim 5: Details a method of treatment involving administering the composition.
- Claim 10: Claims a stable formulation with particular pH and particle size.
Implication: The patent emphasizes both the composition and method of use, broadening scope within treatment applications and formulation variations.
What is the scope of protection?
The patent's claims are broad in scope, covering:
- Variations of the chemical structure with minor modifications, provided they retain the key pharmacological activity.
- Multiple dosage and formulation types, including oral, injectable, and topical forms.
- Methods of treatment for the specified disease, including prophylactic and therapeutic approaches.
This breadth potentially blocks competitors from developing similar formulations or treatment protocols within the scope.
Limitations
- The claims are limited to the specific chemical structure claimed in Claim 1.
- Validity depends on novelty and inventive step compared to prior art (see below).
- Nonobviousness could be challenged if similar compounds or formulations exist.

Key competitors and patent overlap
- Similar structures patentably close to prior-art compounds.
- Risk of invalidation exists if challengers establish lack of novelty, especially with prior disclosures.
- Patent citation analysis shows the patent cites 20 prior patents, mainly from 2005–2015, indicating some reliance on earlier innovations.
Patent expiration
- Expected expiration date: July 14, 2037, assuming no extensions or supplementary protections.
Novelty and inventive step assessment
Prior art references
- Prior art includes compounds with similar core structures disclosed as early as 2010.
- Formulation techniques overlap with methods described in patents from 2012–2014.
- Therapeutic methods are similar to existing approaches, with incremental modifications.
Novelty
- The specific molecular modifications claimed distinguish the compound from prior art.
- Claims on the specific formulation parameters (pH, excipient combinations) likely confer novelty if not disclosed previously.
Non-obviousness
- The patent claims a significant improvement in stability and bioavailability, supported by data.
- The combination of chemical structure and formulation achieves a synergistic effect not obvious to those skilled in the art.
Patentability reviews and challenges
- Patent examiners initially approved the patent based on the claimed inventive step and data.
- Potential challenges include prior art disclosures and arguments of obviousness in formulation improvements.
- The broad claims on methods of treatment may face restrictions if prior art discloses similar protocols.
Strategic considerations for stakeholders
- For licensees: The patent’s broad scope on formulation and method claims offers limited freedom to operate without licensing.
- For competitors: Designing around may involve using alternative chemical structures or different formulation techniques.
- For patent owners: Protecting the core compound and formulation claims remains critical, but there is scope for filing divisional or continuation applications to extend coverage.

FAQs
1. Can this patent be challenged for invalidity?
Yes. If prior art discloses the same compound, formulation, or use, validity can be challenged on grounds of lack of novelty or obviousness.
2. Does the patent cover all formulations of the compound?
No. It specifically claims certain formulations; alternative formulations may be outside its scope.
3. What will happen if the patent expires?
Competitors can then develop and commercialize similar compounds or formulations without licensing restrictions.
4. Can the method claims be enforced independently of the composition?
Generally, yes. Method claims are enforceable as long as the method is performed using the claimed composition or process.
5. Are there restrictions on using similar compounds with slightly modified structures?
Potentially, if modifications fall outside the scope of Claim 1, they may not infringe, but this depends on the specific structural differences.
