Business method patents
Business Method Patents
Overview
Business method patents protect novel and non-obvious ways of conducting business operations, particularly those implemented through technology. These patents have been controversial since their emergence in the late 1990s, following the State Street Bank decision that effectively recognized business methods as patentable subject matter.
Historical Development
Pre-1998 Era
Historically, business methods were considered unpatentable abstract ideas. Courts generally viewed them as falling outside the scope of patent protection, considering them part of the public domain.
The State Street Bank Decision
State Street Bank & Trust Co. v. Signature Financial Group, Inc. (1998) marked a pivotal moment. The court ruled that business methods could be patentable if they produced a "useful, concrete, and tangible result." This decision opened the floodgates for business method patent applications.
Post-Alice Era
The 2014 Supreme Court decision in Alice Corp. v. CLS Bank International significantly impacted business method patents, establishing a two-step test for patent eligibility that made obtaining these patents more challenging.
