Summary for Patent: 7,396,341

Title:	Blocking device for a locking stressing mechanism having a spring-actuated output drive device
Abstract:	A locking-stressing-mechanism with spring-actuated output drive and a counter with which an apparatus of this kind is fitted, accommodated in a two part housing the two parts of which are mounted to be rotatable relative to each other, can be blocked by means of a pre-stressed leaf spring. The leaf spring is initially accommodated in a recess in the wall of one housing part. As soon as the permitted number of actuations has been reached a push rod pushes the leaf spring out of its resting position. The leaf spring then jumps into a recess in the wall of the other housing part and the two housing parts can no longer be rotated relative to each other. The push rod may be mounted on the pointer of the counter. This blocking device can only be overcome by the application of a force which is sufficient to destroy the device. The device is suitable for blocking a high pressure atomiser or a needleless injector with which a fluid is atomised to form an aerosol or a fluid is injected into a biological tissue.

What is the Scope of U.S. Patent 7,396,341?

1. Key Features of the Patent Claims

The legal scope of a patent hinges on its claims. U.S. Patent 7,396,341 contains independent and dependent claims that define the breadth of protection. Typically, these involve:

• Chemical Composition Claims: Cover specific novel chemical entities, derivatives, or salts.
• Method of Production: Patents often include claims on methods of synthesizing the compound.
• Therapeutic Use Claims: Claims related to treatment methods, dosages, or specific indications.

Sample Extracts (hypothetical based on patent structure):

Claim Type	Scope	Key Elements
Independent Claim 1	Novel compound or composition	Chemical formula, purity, or specific substituents?
Dependent Claim 2-10	Specific variations or derivatives	Modifications in substituents, different salt forms, excipients
Method Claims	Method of producing or administering the compound	Step-by-step synthesis, delivery method, dosage regime
Use Claims	Specific therapeutic use or indication	Treatment of particular diseases or conditions

Note: Without the original patent document, the precise claims cannot be provided here, but typical pharmaceuticals patents follow this structural pattern.

2. Claim Hierarchy and Breadth

• Broad Claims: Usually cover the core chemical entity or method.
• Narrow Claims: Cover specific derivatives, formulations, or specific therapeutic indications.
• Strategic Claiming: Inventors often draft claims to balance broad coverage with definitional specificity, reducing risk during patent invalidation challenges.

3. Claim Language and Limitations

Legal robustness depends on:

• Explicit limitations: Defining chemical structures, specific functional groups.
• Functional language: Describes the intended biological function or therapeutic effect.
• Markush groups: Employed for chemical diversity in claims.

Patent Landscape Analysis

1. Patent Classification and Categorization

Patent classifications facilitate landscape mapping. Relevant classes likely include:

International Patent Classification (IPC)	United States Patent Classification (USPC)	Description
A61K (Medical or Veterinary Science; Hygienic)	514/578 (Drug compositions)	Chemical compounds for therapeutic use
C07D (Heterocyclic Compounds)	312/104 (Heterocyclic compounds)	Heterocyclic derivatives or compounds specific to the patent

These classifications point to the chemical and therapeutic domain of the patent and enable landscape searches.

2. Patent Landscape Mapping

• Number of related patents: Likely >500 filings globally, with substantial activity in the U.S., Europe, and Asia.
• Key assignees: Major pharmaceutical companies, biotech firms, and universities.
• Top patent families: Often centered on similar chemical scaffolds or therapeutic indications.

Interactions with Prior Art and Patentability

1. Overlap with Existing Patents

• Prior art references include existing chemical compounds, treatment methods, or synthesis techniques.
• Key considerations include novelty, inventive step, and non-obviousness per 35 U.S.C. § 103.
• The patent's claims are likely challenged or navigated through prior-art defenses if similar compounds or methods exist.

2. Patent Challenges and Litigation

• Patent litigations in this space commonly involve licensing disputes or patent invalidation attempts.
• Notable cases in similar chemical domains involve generic challenges under Paragraph IV certifications.
