Patent prosecution involves the process of preparing and filing patent applications with the appropriate government agency, typically the United States Patent and Trademark Office (USPTO). This process includes communicating with patent examiners, responding to office actions, and making arguments to secure the grant of a patent. Patent prosecution also encompasses the negotiation and drafting of patent claims to define the scope of protection for the invention. Additionally, patent prosecution may involve post-grant proceedings such as reexamination or inter partes review.
