Understanding Patent Claims
What are Patent Claims?
Patent claims define the scope of the invention and are the most critical part of a patent. They outline what the inventor considers to be the novel and non-obvious aspects of the invention[3].
Analyzing Claims
For U.S. Patent 5,856,355, you would carefully read through the claims section. Here are some steps to follow:
