Data for: 3D bioprinting patents

This dataset contains information regarding 3D bioprinting patent/patent applications. 

Orbit (a fee-based patent database provided by Questel), accessed on Jan. 2, 2022, was used for data mining.

The files titled “3D bioprinting patents” and “Bioink patents” contain information related to Priority, Application and Publication numbers, Priority Application and Publication dates, Title, Abstract, and Current assignees.

The patent searches were carried out by keywords and classification codes. 

Both IPC (International Patent Classification) and CPC (Cooperative Patent Classification) codes were used. 

Instead of 309 patents (see reference 1), a total number of 3,681 documents were retrieved (of which 3,027 are still alive and 2,461 filed in the period 2016 – 2020).

Most of the published patent applications were generated in China and the USA (1,360 vs 1,063 priority applications). China is effectively the leading country (37%), followed by the USA with 29% of priority patent applications. 

Value of the dataset: prior art searches, technological trends
