“The name of the game is the claim,” once noted Judge Giles Rich, who helped shape US patent law policy and the 1952 Patent Act. More than 70 years later, Judge Rich’s observation still rings true. Available now, the Eighth Edition of Mechanics of Patent Claim Drafting presents the most recent aspects of patent eligibility law, new developments in patentability law, and the latest trends in patent claim drafting. 2023 Co-Editor Thomas J. Kowalski, a partner at the Duane Morris law firm, offers a few key insights to emphasize why this is a must-have resource for patent lawyers and patent practitioners. Published by The Practising Law Institute, Mechanics of Patent Claim Drafting may be ordered online at Faber & Kowalski on Mechanics of Patent Claim Drafting (Eighth Edition) (pli.edu)
According to Co-Editor Kowalski, “Patent claim drafting is an art that calls for defining an invention or a class of inventions in sentence.” Against this background, the Mechanics of Patent Claim Drafting provides something for each patent practitioner, regardless of level of experience. It offers comprehensive reference materials including up-to-date information on patent law. This treatise is a one-stop source for information on how to construct a patent claim – across various technologies, including biotechnology and computer science – as well as for detailed information on the law of patent-eligibility and patentability, along with classic patent claiming exemplification and relevant mechanical reference material.
“There is no other book that provides, in one volume, cover-to-cover, a comprehensive presentation on the basics and fundamentals of patent claim drafting,” noted Kowalski. “Across all technologies, it is a detailed discussion of relevant patent law, along with classic exemplification and useful reference material.”
