In the last decade, some new technological design or modifications of existing design of high pressure extraction apparatuses have been also patented. In this review, only patents published in English and which have made a significant contribution to the already existing knowledge by disclosing a method, a device, a process or the integration with other systems and/or applicable to a wide range of feed materials are presented. The authors do not claim the list is exhaustive and even did not intend to do so. This work only aims to highlight the most significant developments since the new century. Generally, most patents are issued 1–5 years after the patent was first filed and the standard term of validity is for 20 years: therefore, only those patents published on or after 2000 are mentioned here: see Table 2. In what follows, each patent cited in Table 2 is shortly discussed.
