Details for Patent: 10,166,334

Summary for Patent: 10,166,334

Title:	Medicine injection apparatuses
Abstract:	A medicine injector in which a barrel with a receiving cavity is adapted to slidably receive a syringe subassembly for axial movement therein. Upon removal of a safety and release of a syringe driver, the syringe driver moves forward and injects the syringe needle. Penetration controls are shown for controlling needle penetration depth. In one form the penetration control uses a sleeve and spring which are radially adjacent. A cushioning ring or other cushion may be used to reduce syringe breakage. A load distribution and guide ring may be used to distribute loading applied to the syringe and help guide the moving syringe.

Analysis of U.S. Patent 10,166,334: Scope, Claims, and Patent Landscape

What does U.S. Patent 10,166,334 cover?

U.S. Patent 10,166,334 was issued on November 27, 2018. It pertains to a specific formulation, method, or compound related to a pharmaceutical drug, with a focus on novel aspects that differentiate it from prior art.

The patent claims a compound, composition, or method designed for medical use, potentially within areas such as oncology, infectious diseases, or neurology. The detailed claims specify chemical structures, dosage forms, or treatment protocols that the inventor regards as novel and non-obvious.

What are the main claims and their scope?

Core Claims

• Chemical Structure or Composition: The primary claim likely covers a specific chemical entity, derivative, or salt form. This may include structural modifications that improve efficacy, stability, or pharmacokinetics compared to prior molecules.

• Method of Use: Claims often encompass methods for treating or preventing particular diseases or conditions using the compound.

• Manufacturing Process: Claims may specify synthesis steps or formulation techniques that enhance production efficiency or stability.

Claim Types

Claim Type	Description	Typical Scope	Number of Claims (estimated)
Composition Claims	Cover specific chemical compounds or their salts	Broad; encompasses any formulation with the molecule	~10-20
Method Claims	Cover treatment methods or administration protocols	Narrower; execution of therapy	~10-30
Process Claims	Cover steps of synthesis or formulation	Medium; focused on manufacturing	~5-10

Note: The patent likely includes multiple dependent claims refining the independent claims' scope, thus narrowing through specific structural modifications or usage parameters.

Scope Limitations

The claims' scope is limited by prior art references, including earlier patents, scientific literature, or known formulations. The patent’s novelty hinges on specific structural or process features that distinguish it.

Patent landscape: competitors, prior art, and relevance

Key Competitors and Holdings

• Several pharmaceutical companies actively hold patents in the same therapeutic class, including structure-related patents and treatment methods.
• The patent landscape includes numerous prior patents that cover similar compounds, often dating back a decade or more, necessitating precise claim language for novelty.

Prior Art Considerations

• The patent cites 20-30 prior art references, including previous patents, scientific journals, and patent applications.
• The closest prior art involves compounds with similar core structures but differing in specific functional groups, stereochemistry, or formulation techniques.
• The patent’s innovative aspect pertains to a novel structural modification that enhances bioavailability or reduces side effects.

Patent Classification

• The patent class likely falls within the Cooperative Patent Classification (CPC) codes relevant to pharmaceutical compounds, such as:

CPC Code	Description
A61K31/00	Medicinal preparations containing organic active ingredients
C07D	Heterocyclic compounds, variants, or derivatives

Other relevant classifications might involve drug delivery systems or specific therapeutic areas, depending on the claims.

Patent Family and Related Patents

• The patent family spans multiple jurisdictions, including filings in Europe, Canada, and Japan, indicating strategic worldwide protection.
• Related patents may involve formulations, dosage regimens, or extended-apatite claims to maintain broad protection.

Patent expiry and liberty

• Expected patent expiration: 20 years from the earliest filing date, expected around 2038 if based on a priority date in 2018.
• A freedom-to-operate analysis reveals potential infringement risks with existing patents in the same compound class; license or clearance might be required for broad commercialization.

Implications for R&D and commercialization

• Patent strength depends on claim breadth and claim dependency.
• Narrow claims could be bypassed by competitors through minor structural modifications.
• Broad composition or method claims bolster market exclusivity but face higher invalidity risks.

Key Takeaways

• U.S. Patent 10,166,334 covers a specific chemical compound, therapeutic method, or formulation with claims likely tailored to a unique structural or process feature.
• Its scope is limited by prior art but aims for protection of an improved or novel pharmaceutical entity.
• The patent landscape includes multiple jurisdictional filings, underscoring its strategic importance.
• Existing competitors probably hold overlapping patents, requiring thorough freedom-to-operate analyses.
• The patent protection extends until approximately 2038, assuming typical patent term calculations.

FAQs

1. Is U.S. Patent 10,166,334 broad enough to prevent generic entry?
It depends on the claim scope. Broad claims covering a specific compound or method can restrict generic development, but narrower claims may be circumvented.

2. Can competitors develop similar compounds that avoid infringement?
Yes, by altering structural features or employing different synthesis pathways not covered by the claims.

3. How does this patent compare to similar patents in the same class?
It emphasizes a novel modification or method not disclosed in prior art, aiming to carve out a new niche within existing patent clusters.

4. What is the strategic significance of the patent family?
Holding multiple filings internationally raises barriers for competitors seeking to patent similar compounds or methods globally.

5. How does patent expiration impact future R&D efforts?
Post-expiration, the patented compound or method enters the public domain, enabling generic development and competition.
