Equally useful to seasoned patent attorneys and newcomers to the field, Landis offers: - Start-to-finish directions for each type of claim apparatus or machine, method or process, composition of matter, article of manufacture, and biotechnology - Model claims for computer inventions, biotechnology inventions, machines, processes, plants, design, and much more - Advice on reviewing your claims so that you catch errors and weed out superfluous language - Real-world examples of dependent claims, Jepson claims, generic and species claims, subcombination claims, and more - Technical dos and donts that help you steer clear of typical claims traps and pitfalls - Quotations from claims on appeal and in litigation that illustrate limitations and phrases which have been approved or rejected - Discussions of case law behind various non-art rejections, covering both classic rules and modern trends As always, Landis gives you the very latest word on patent claim drafting, including a new sample exercise for drafting business method claims. Youll learn new ways to deal with claims that involve numerical ranges -- how to understand the different treatments of preamble language, including the CAFCs Catalina Marketing guidelines -- how the CAFC treated the unusual Markush grouping in the Abbott Laboratories case -- how the CAFC interprets "substantially", "essentially", "similar", and other words of approximation, and why "about" has been held not to be per se indefinite -- why not only "more" and "less" but also "rich" and "high" are comparative words -- how PTO Utility Examination Guidelines address the issue of utility standards for gene and gene fragment patents -- and how new case law affects means or step clauses, alternative expressions, and product-by-process claims. Plus, the text has been redesigned and reorganized for ease of use.
