Enforceability of patent rights is the backbone of the patent system. We review differences in the way patent litigation systems are designed across jurisdictions. We also discuss challenges in collecting and accessing patent litigation data as well as their economic analysis. We provide some descriptive analysis of patent litigation in the U.S. and UK for the period 2010-2016 and 2007-2013, respectively. We also analyze administrative post-grant validity challenges in form of the inter partes review in the U.S. and oppositions at the EPO.

Winning the Patent Damages Case serves as a guide to patent litigators and in-house counsel who are either considering an action for patent infringement or who are facing the spectre of a lengthy, expensive litigation. It offers readers an analytical framework for determining the likely damages award in a patent case, which is critical to the decision of whether to settle the case and for how much. It provides valuable information on how to structure the patent case from the outset and assists accused infringers in how to prepare a "shadow" damages case that may result in a much more reasonable damages award in the event of a loss. Finally, the book provides practical suggestions on how to select and work with a damages expert. The second edition discusses the Federal Circuit's decision in Lucent v. Gateway on the entire market rule and damages allocation, as well as subsequent decisions which have employed its reasoning. Other new developments include whether plaintiffs can use licenses obtained in litigation to prove an "established royalty" under the Georgia-Pacific factor No.1; and courts awarding ongoing royalties instead of imposing injunctions.

In this paper, the authors describe and explore a new algorithmic approach to constructing concordances between the International Patent Classification (IPC) system and industry classification systems that organize economic data. This ‘Algorithmic Links with Probabilities’ (ALP) approach incorporates text analysis software and keyword extraction programs and applies them to a comprehensive patent dataset. The authors conclude with a discussion on some of the possible applications of the concordance and provide a sample analysis that uses their preferred ALP concordance to analyze international patent flows based on trade patterns.

This volume assembles papers commissioned by the National Research Council's Board on Science, Technology, and Economic Policy (STEP) to inform judgments about the significant institutional and policy changes in the patent system made over the past two decades. The chapters fall into three areas. The first four chapters consider the determinants and effects of changes in patent "quality." Quality refers to whether patents issued by the U.S. Patent and Trademark Office (USPTO) meet the statutory standards of patentability, including novelty, nonobviousness, and utility. The fifth and sixth chapters consider the growth in patent litigation, which may itself be a function of changes in the quality of contested patents. The final three chapters explore controversies associated with the extension of patents into new domains of technology, including biomedicine, software, and business methods.

In Patent Litigation in China, Douglas Clark provides U.S. and other non-Chinese practitioners with an overview of the patent litigation system in China and with strategic commentary to ensure better decision-making by those responsible for bringing or defending patent actions in China.

In recent years, business leaders, policymakers, and inventors have complained to the media and to Congress that today's patent system stifles innovation instead of fostering it. But like the infamous patent on the peanut butter and jelly sandwich, much of the cited evidence about the patent system is pure anecdote--making realistic policy formation difficult. Is the patent system fundamentally broken, or can it be fixed with a few modest reforms? Moving beyond rhetoric, Patent Failure provides the first authoritative and comprehensive look at the economic performance of patents in forty years. James Bessen and Michael Meurer ask whether patents work well as property rights, and, if not, what institutional and legal reforms are necessary to make the patent system more effective. Patent Failure presents a wide range of empirical evidence from history, law, and economics. The book's findings are stark and conclusive. While patents do provide incentives to invest in research, development, and commercialization, for most businesses today, patents fail to provide predictable property rights. Instead, they produce costly disputes and excessive litigation that outweigh positive incentives. Only in some sectors, such as the pharmaceutical industry, do patents act as advertised, with their benefits outweighing the related costs. By showing how the patent system has fallen short in providing predictable legal boundaries, Patent Failure serves as a call for change in institutions and laws. There are no simple solutions, but Bessen and Meurer's reform proposals need to be heard. The health and competitiveness of the nation's economy depend on it.
