Antibody Patenting: A Practitioner's Guide to Drafting, Prosecution and Enforcement (CRC)

Antibody Patenting provides a comprehensive and in-depth analysis of all aspects relating to the patenting of antibodies from initial drafting and prosecution to enforcement. Antibodies have revolutionized medicine and biotechnology, and have become indispensable tools in therapy, diagnostics, analytics, and research. Therapeutic antibodies, for example, have come to dominate the ranks of blockbuster drugs, currently accounting for 10 out of the top 15 best-selling medicines. At the same time, a body of case law dealing specifically with the patentability of antibody-related inventions and the enforcement of antibody patents has emerged in major jurisdictions. The, at times, significant divergences between different jurisdictions have been compounded by recent decisions in the United States, most notably Amgen v. Sanofi, 872 F.3d 1367 (Fed. Cir. 2017), which have severely curtailed the possibilities to obtain broad antibody patents. It is therefore essential to understand how antibody inventions are assessed in different jurisdictions in order to secure an optimal patent protection and to successfully enforce such patents.

What’s in this book:

This book covers 23 of the most important IP jurisdictions worldwide – i.e., the European Patent Office, France, Germany, Italy, the Netherlands, Poland, Spain, Switzerland, the United Kingdom, Israel, the United States of America, Argentina, the Andean Community (Bolivia, Colombia, Ecuador, and Peru), Brazil, Canada, Chile, Mexico, China, India, Japan, Singapore, South Korea, and Australia. The 35 contributors to this book, all distinguished experts in this field, provide clear and practice-oriented advice on a range of topics including:

• Which types of antibody inventions are patent-eligible?
• Which types of functional and structural features are accepted for claiming antibodies?
• What needs to be considered when defining antibodies in terms of their antigen, target affinity, binding specificity, epitope, competitive binding and other characteristics in relation to reference antibodies, as well as their effects on the target?
• Which pitfalls must be avoided when defining amino acid sequences, chemical modifications or glycosylation patterns, and when relying on cell line deposits?
• Which breadth of claims is accepted for antibody inventions, and what experimental support is required?
• Which specific medical applications of antibodies can be claimed?
• How is inventive step assessed in the specific case of antibody inventions?
• What has to be considered when enforcing antibody patents, including in relation to biosimilars as well as the doctrine of equivalence?

All chapters follow the same structure, which makes this book easily accessible and allows a direct comparison between different jurisdictions. Practitioners will find the much-needed tools and guidance to secure the best possible patent protection for antibody inventions in 23 of the most important jurisdictions worldwide.

How this will help you:

This book is the fifth volume in the AIPPI Law Series, which has been established together with AIPPI, a non-affiliated, non-profit organization dedicated to improving and promoting the protection of intellectual property at both national and international levels. Structured in a country-by-country format, it provides practitioners with a comprehensive resource elucidating all aspects of the patenting of antibodies.
