The data in this article includes biotechnological joint patents as a proxy of technological alliances. Joint patents are not directly found in public or commercial databases. Each joint patent has their corresponding International Patent Classification codes, their forward citation measure as an indicator of innovation value, and the firms involved in the process. The data was collected during a time frame that ranges from 2006 to 2010. Data from the joint biotechnological patents was collected at first during the time window, and then filtered, cleaned, and sampled accordingly to obtain 340 joint patents between firms (e.g. alliances) in the industry. Then each of the joint patents was processed to find the forward citations they have. Data on joint patents of biotechnology industry can be reused in future studies related to technological alliances and patenting mechanisms and process.
