Constraints on gene patent protection fuel secrecy concerns: a qualitative study

Christi J Guerrini, Amy L McGuire, Mary A Majumder, Juli M Bollinger, Paul J Rowan
2017 Journal of Law and the Biosciences  
We conducted semi-structured interviews of legal and scientific experts (n = 30) to understand the effect of recent patent eligibility changes on interest in patenting and trade secrecy of genetic innovations  ...  Due to the clandestine nature of trade secrets, it is impossible to quantify the extent to which innovators actually elect to protect their inventions as trade secrets rather than patents.  ...  The authors thank Arthur Rogers for his suggestions on an early draft of this manuscript.  ...
