I don't know if any biopharma company has been involved in the process/research. Here is a list of multinational researchers and contributors -
Dhirendra K. Simanshu, Ravi Kanth Kamlekar, Dayanjan S. Wijesinghe, Xianqiong Zou, Xiuhong Zhai, Shrawan K. Mishra, Julian G. Molotkovsky, Lucy Malinina, Edward H. Hinchcliffe, Charles E. Chalfant, Rhoderick E. Brown & Dinshaw J. Patel - all published in PubMed, some of them may be affiliated with private companies.
The actual findings were submitted to Nature in July of 2012, and published a year after, so it's possible that active product research and/or trials are being done.
