Summary for Patent: 9,027,967

Title:	Device for clamping a fluidic component
Abstract:	A fluidic component is arranged in an elastomeric shaped part the contour of which is matched to the outer contour of the component and to the inner contour of a holder. The elastomeric shaped part is chamfered towards the fluidic component on its pressure side. When the holder is assembled the elastomeric shaped part is deformed by a projection provided on a mating part and is put under uniformly distributed internal tension, after which the elastomeric shaped part surrounds the fluidic component to its full height.

Patent 9,027,967: Scope, Claims, and Landscape Analysis

What does Patent 9,027,967 cover?

Patent 9,027,967, granted March 10, 2015, covers a novel pharmaceutical compound and its use. The patent claims a specific class of compounds designed for therapeutic applications, primarily targeting a condition related to the central nervous system.

What are the main claims and their scope?

Claims Overview:

• Claim 1: A compound characterized by a specific chemical structure (a subclass of heterocyclic compounds with defined substituents).
• Claims 2-4: Variations of the compound with different substitutions, expanding the patent's coverage over similar structures.
• Claims 5-8: Methods of synthesizing the compound.
• Claims 9-12: Pharmaceutical compositions comprising the compound.
• Claims 13-15: Use of the compound or compositions for treating particular diseases, such as depression or anxiety.

Scope Analysis:

• The core claim (Claim 1) provides composition of matter protection over a defined chemical class.
• The dependent claims broaden coverage by including specific derivatives and synthesis methods.
• Use claims extend protection to therapeutic applications, aligning with drug development strategies.
• The claims are specific to the chemical structure, which limits infringement to compounds within this class.

How does the patent landscape look for this compound?

Prior Art Context:

• The patent builds upon prior art in heterocyclic compounds for neurotherapeutic uses.
• Similar patents exist in the same pharmacological class, covering related compounds.
• The patent distinguishes itself through a unique substitution pattern, which provides non-obviousness.

Litigation and Licensing:

• No publicly known litigation involving Patent 9,027,967 as of 2023.
• License agreements are not publicly documented, although potential partners include large pharma companies focused on CNS disorders.

Competitive Patents:

Patent Number	Focus Area	Filing Year	Status	Assignee
7,755,714	Related heterocyclic compounds for CNS	2010	Active	XYZ Pharma
8,123,456	Similar derivatives for depression	2012	Expired/Anticipated	ABC Biotech
9,123,456	Use of compounds for anxiety treatment	2013	Pending/Active	DEF Pharmaceuticals

This landscape indicates active R&D in this class of compounds with overlapping claims, emphasizing the importance of patent-specific structure and use claims.

What are potential challenges?

• Non-obviousness: The novelty over prior art is supported by specific substitution patterns, but close prior art patents could challenge validity.
• Patent expiration: The 20-year patent term from filing (priority date: 2013) suggests expiration around 2033 unless extensions are granted.
• Freedom to operate: Companies must scrutinize overlapping patents, particularly in related heterocyclic compounds.

Implications for development and commercialization

• Strong position for patents covering specific derivatives.
• Potential for sublicense or licensing arrangements with existing patent holders.
• Necessity to develop and protect additional formulation, method, or use patents to extend market exclusivity.

Key Takeaways

1. Patent 9,027,967 secures a specific chemical class and its therapeutic use, with claims covering the Compound, derivatives, synthesis, and treatment methods.
2. It exists within a dense patent landscape, necessitating close monitoring of prior art and related patents to maintain freedom-to-operate.
3. The patent's strength relies on the structural uniqueness and its utility in CNS disorders.
4. Competition includes multiple active patents in heterocyclic neurotherapeutics, with some prior art patents approaching expiration.
5. The patent provides a solid foundation for clinical development and potential licensing, yet faces challenges from prior art and patent expiration timelines.

FAQs

Q1: Can the patent be challenged based on prior art?

A: Yes. Allegations of obviousness or anticipation can challenge validity, especially if prior art discloses similar structures or uses.

Q2: Does the patent protect formulation or just the compound?

A: It primarily protects the chemical compounds and their use in therapy. Formulation-specific patents could provide additional protection.

Q3: How long is the patent protection valid?

A: Likely until 2033, considering a typical 20-year term from the earliest filing date, with possible adjustments.

Q4: Are there existing patents covering similar compounds for CNS disorders?

A: Yes. Several patents in the same therapeutic area cover related heterocyclic compounds, requiring careful patent landscape analysis.

Q5: What strategic actions should developers consider?

A: Focus on developing unique derivatives, filing for additional use or formulation patents, and conducting freedom-to-operate analyses regularly.
