Global Patent Protection and Enforcement of In Vitro Diagnostic Inventions describes the patentability requirements and enforcement challenges faced by in vitro diagnostic inventions in nine major worldwide markets, providing practical tips on how to overcome these challenges and build a globally enforceable patent portfolio for such inventions. Patent protection for the makers of these diagnostics is vital since obtaining regulatory approval is a time-consuming and expensive process. Like all inventors, developers of in vitro medical diagnostic tests depend on patent protection that is enforceable against alleged infringers and ensure royalties and other payments. Due to recent United States (US) court decisions that have made the patentability of such tests untenable in the US, there is an expectation that patent applications for in vitro diagnostic inventions will increase in commercially important countries that provide broader protection.
