In an earlier era, PTO guidelines essentially rejected the notion that computer programs could be patented. As technology progressed, courts began to interpret the statutory subject matter of the Patent Act more expansively, to adapt old principles to the modern era of computer technology. The court in State Street was correct to jettison the business method exception from patent law. The exception, born out of dicta almost a century ago, lacked justification, caused confusion and unfairly limited the scope of patentable subject matter. Patents are as necessary for e-commerce as for any other industry.
Patents provide the incentive to innovate.
While fears of patent protection will always surround new innovations, patentability of e-commerce technology will not stifle competition.
