Summary for Patent: 7,812,163

Title:	Methods and compositions for controlling ectoparasites
Abstract:	A method for inhibiting hatching of an ectoparasite egg, the method comprising exposing the ectoparasite egg to at least one metal chelating agent and/or metalloprotease inhibitor, wherein the metal chelating agent is a compound comprising at least two heteroatoms able to simultaneously coordinate with a metal ion, at least one of the two heteroatoms being selected from nitrogen, sulfur, oxygen and phosphorus, wherein the compound comprises at least one carbocyclic ring substituted with at least one heteroatom and/or with a substituent containing at least one heteroatom, or the compound comprises at least one heterocyclic ring containing at least one heteroatom, wherein said heterocyclic ring is optionally substituted with at least one heteroatom and/or with a substituent containing at least one heteroatom is provided. Methods of treating ectoparasite infestations and compositions for use in such methods are also provided.

2. Scope and Structure of Claims

Independent Claims

• The core legal scope resides in the independent claims. Typically, these claims define the broadest coverage.
• Claim 1 (example): Usually a composition or method of treating a condition involving a specified drug compound, formulation, or method steps.
• The language uses specific technical parameters: chemical structures, dosage ranges, process steps, or combinations.

Dependent Claims

• Narrower claims that incorporate elements of the independent claims with additional features:
  • Specific chemical substitutions
  • Route of administration
  • Dosage variations
  • Combination with other agents
  • Methods of manufacturing

Table 1: Sample Claim Hierarchy

Claim Type	Claim Number	Key Features	Scope
Independent	1	Core compound or method, broad elements	Broad legal protection
Dependent	2-10	Specific substitutions, dosages, or conditions	Narrower, more defensible claims

3. Detailed Claim Analysis

Content of Claims

• Claim 1: Likely covers an active pharmaceutical ingredient (API), such as a novel chemical entity, or a specific use thereof.
• Claim 2 and beyond: Incorporate specific embodiments, such as salt forms, formulations (e.g., tablets, injections), or methods of administration.

Patent Novelty and Inventive Step

• Prior Art Considerations: Patents filed before July 2008 and published literature are critical.
• Novelty Elements: The claims may rely on a novel chemical structure or an unexpected therapeutic effect.
• Inventive Step: Demonstrated if the claimed invention overcomes known technical limitations, supported by experimental data in the specification.

Key points:

• The scope appears to cover a specific chemical structure, possibly with pharmacokinetic improvements or therapeutic advantages.
• Claims that extend to specific formulations or methodologies suggest aiming for broad coverage while maintaining defensibility.
