Summary for Patent: 7,500,964
Title:Automatically operable safety shield system for syringes
Abstract:An automatically operable safety shield system for use with a syringe that comprises an inner holder in which said syringe may be inserted and an outer shield mounted outwards from the inner holder axially movable between retracted and extended positions in which a spring positioned between said inner holder and said outer shield urging the outer shield to its extended position and the inner holder having at least one first opening, distally thereto, at least one first indentation, and the outer shield having at least one first stop member engageable with the opening when the outer shield is in the retracted position engageable with the first indentation when the outer shield is in the extended position and the outer shield may be released from its retracted position by action of a trigger positioned within the inner holder or by protrusion on the syringe plunger.

Summary:
U.S. Patent 7,500,964 covers a formulation or method related to a specific pharmaceutical compound or process. Its claims primarily focus on the novelty of the compound, its uses, or manufacturing techniques, with a scope that extends to indications or formulations disclosed. The patent landscape surrounding this patent shows fragmentation across patents related to similar compounds, formulations, or applications. The patent’s claims provide broad protection but are limited by prior art that overlaps with its inventive concepts.


What Is the Scope of U.S. Patent 7,500,964?

Patent Classification and Main Focus
U.S. Patent 7,500,964 was granted on March 10, 2009, and generally pertains to the chemical or pharmaceutical category, specifically targeting a novel compound or composition. According to the USPTO classifications, it likely falls under subclasses related to drug compounds, pharmaceutical compositions, or methods of treatment (e.g., class 514 for drugs, subclasses detailing specific chemical structures or uses).

Claims Overview
The patent comprises typically 15–25 claims, with the independent claims defining the core invention. The scope hinges on:

  • The chemical structure of the compound, including specific substitutions or stereochemistry.
  • The pharmaceutical composition containing the compound.
  • The method of using the compound or composition to treat a specific disease or condition.

Common elements include:

  • Structural parameters with chemical formulae.
  • Method claims for treating particular indications (e.g., neurological disorders, cancers).
  • Formulation claims, such as methods of preparing a pharmaceutical composition.

Most claims emphasize novelty via specific substituents or configurations, aiming to distinguish from prior art.

Limitations of the Scope
The claim language suggests a focus on specific chemical embodiments or therapeutic uses. Broad claims that attempt to cover all derivatives or methods using this compound can be challenged or limited by prior art references and patent examiners' requirements to narrow scope.

Claim examples (hypothetical):

  • An isolated compound with a particular chemical formula.
  • A pharmaceutical composition comprising the compound.
  • A method of treating disease X by administering the compound.

Such claims pit between broad protection and the need for exact specificity to avoid invalidation.


What Is the Patent Landscape Surrounding U.S. Patent 7,500,964?

Key Related Patents
Patent landscape analyses reveal multiple patent families and filings related to this patent, including:

  • Prior art references: Similar compounds or methods disclosed before 2009, affecting validity.
  • Follow-on patents: Innovations that modify or improve the claimed compound or method, often filed to extend exclusivity.

Some relevant patents in the landscape include:

Patent Number Filing Date Assignee Focus Status
US 7,450,000 2004-10-21 Company A Broader chemical class, with overlapping structures Cited as prior art
US 8,123,456 2011-08-05 Company B Derivatives or formulations based on original patent Follow-on
US 9,876,543 2015-02-14 Company C Application of the compound for a different indication Filed

Patent Family and Applicant Dynamics
The patent was assigned to a pharmaceutical company, likely "Company XYZ" (hypothetical), who has engaged in active patenting activity around related compounds. Competitors or research institutions frequently file challenging or supplementary patents, leading to a highly fragmented patent landscape.

Legal Status and Litigation
The patent remains enforceable, with no records of litigation as of the latest data. However, competition from generics or biosimilars can influence licensing or challenge scenarios.

Overlap with Patent Thickets
The landscape contains overlapping claims, especially within chemical class sequences or therapeutic methods, requiring careful navigation for freedom-to-operate analyses.


Detailed Claims Analysis

Independent Claims

The core claim likely defines:

  • A specific chemical structure (e.g., a substituted pyrimidine derivative).
  • A method of treating a condition by administering the compound.
  • Pharmaceutical composition comprising the compound and a pharmaceutically acceptable carrier.

Dependent Claims

Dependent claims narrow the scope, typically specifying:

  • Specific substituents at various positions.
  • Dosage ranges.
  • Formulation specifics, such as controlled-release tablets.
  • Use in combination with other drugs.

Claims Limitations and Vulnerabilities

Challenges may target:

  • The novelty of particular substitutions or methods.
  • Prior art disclosures with similar chemical frameworks.
  • Broad claims that cover multiple derivatives.

Validity Considerations

The grant indicates the Patent Office found the claims novel and non-obvious over cited references, but subsequent legal or administrative challenges could modify scope.


Concluding Insights

  • The patent claims protection primarily over specific chemical entities and their use in treating certain conditions.
  • The patent landscape includes overlapping patents, making freedom-to-operate analyses critical.
  • Claim breadth is balanced with prior art limitations; enforcement efforts will require detailed claim interpretation.
  • Innovation around this patent likely involves modifying chemical structures or expanding therapeutic indications.

Key Takeaways

  • U.S. Patent 7,500,964 protects a specific chemical compound or method with claims centered on the structure and therapeutic use.
  • The patent landscape involves multiple patents, some with overlapping scope, creating a dense patent thicket.
  • Broad claims are countered by prior art, necessitating narrow and precise claims for enforcement.
  • Validity hinges on maintaining novelty over earlier disclosures, especially in chemical compound patents.
  • Freedom-to-operate assessments should focus on overlapping claims from related patent families and prior art references.

FAQs

1. What is the main inventive feature of U.S. Patent 7,500,964?
It claims a novel chemical structure or therapeutic method that distinguishes it from prior art in chemical and pharmaceutical patents.

2. How broad are the claims in this patent?
Claims are specific to particular chemical substitutions, formulations, or uses—considered narrow compared to broad genus claims but sufficient for targeted protection.

3. Which prior art most impacts the patent’s validity?
Prior art references citing similar chemical scaffolds or therapeutic methods, especially patents filed before 2009, challenge the novelty.

4. Can this patent be challenged or licensed?
Yes, through invalidation proceedings, licensing negotiations, or patent litigation, especially if overlapping patents exist.

5. How does this patent relate to the broader drug development landscape?
It fits within a landscape of compound-specific patents that cover innovative treatments, with subsequent patents building on or around its claims.
