That ruling produced an explosion in business-method patent filings， initially by emerging internet companies trying to stake out exclusive rights to specific types of online transactions. Later， move established companies raced to add such patents to their files， if only as a defensive move against rivals that might beat them to the punch. In 2005， IBM noted in a court filing that it had been issued more than 300 business-method patents despite the fact that it questioned the legal basis for granting them.
