Patent Claims and Scope
Claim Structure
Patent claims are the heart of any patent, defining the scope of the invention. The '929 patent, like other patents, would have a set of claims that outline what is novel and non-obvious about the invention. These claims can be independent or dependent, with dependent claims building upon the independent claims[3].
Claim Analysis
To understand the scope of the '929 patent, one would need to analyze each claim carefully. Here are some key aspects to consider:
- Independent Claims: These define the broadest scope of the invention and are typically more general.
- Dependent Claims: These narrow down the invention by adding specific limitations to the independent claims.
- Claim Language: The clarity and specificity of the claim language are crucial. Broadly worded claims can lead to ambiguity and potential legal issues[4].
