Grant rate for U.S. chemical patents is up

Discussion created by Clifton McCann on Aug 20, 2015

The grant rate for U.S. patents has risen steadily since 2009, notwithstanding Supreme Court decisions that have disfavored patent applicants.  The chemical patent grant rate rose from 48% in 2009 to 67% in 2014.  The Court's Alice v. CLS Bank decision (2014) is wreaking havoc on business method and software patents, but has had no significant impact on patents in the chemical arts.
