Patent prosecution data is crucial in understanding how the current patent provisions and case law are interpreted and applied. Considering the importance of patent prosecution data and the scope of this book, the present chapter reports the results of an empirical analysis using the publicly available patent prosecution data from patent applications with claims directed to bioprinted tissues and bioinks in Australia, the US, and the EU. The insights provided in this chapter will also contribute towards answering the overarching research question of this book, and will also address some of the subsidiary research questions, particularly ‘What types of patent claims are being applied for and granted/objected to in relation to 3D bioprinted tissues and bioinks?’ and ‘How are patent offices currently assessing and responding to patent claims related to 3D bioprinted tissues and bioinks?’ This chapter provides insights into how patent examiners are interpreting and applying the patent provisions related to patentable subject matter and other patentability criteria to accept or object to specific subject matter related to bioprinting tissue and bioinks. A comparative approach has been employed in analysing the results and insights of the patent prosecution data analysis. Considering the research questions and the scope of this book, the patent prosecution data analysis is primarily focused on patentable subject matter requirements, with a briefer overview of the other patentability criteria, these being novelty, inventive step, utility, and the disclosure requirements.
