The proposed change to the patent system is bound to have a chilling effect on scientific research.
Evidence
Under current rules, PC → DC researchers have one full year after the initial publication of a new discovery to patent the discovery.
This allows research results to be shared widely prior to the patent application.
The proposed change would have the application precede initial publication, which would delay the communication of discoveries.
Conclusion
The proposed change DC → CESR to the patent system is bound to have a chilling effect on scientific research.
Evaluate
The argument assumes DC → CESR that if communication of discoveries is delayed, it would have a chilling effect on scientific research.
