What is a Patent Claim?

Patent claims are an essential part of a patent application. They define the scope of protection conferred by a patent and the subject matter that’s protected by it. In other words, the claims are the legal definition of what the patent covers and what it doesn’t. The purpose of the claims is to provide notice to others of what they must not do if they’re to avoid infringement liability. The claims are of paramount importance in both prosecution and litigation. If you have any more questions about this, I’d consider consulting with an experienced patent attorney.
