The U.S. Supreme Court has taken a case involving the issue of when software is patentable, The Wall Street Journal reports. The tech world is divided on where to draw the line on when software can be patented and when it can't: "On one side lie technology giants such as Google Inc., Facebook Inc., and Intuit Inc., which largely believe the Patent & Trademark Office has issued too many software patents in recent years, and would like to see courts apply a more exacting standard when reviewing them. On the other, lies a collection of big and small technology companies, including International Business Machines Corp., which worry that tighter standards on software patents could hurt innovation," The Journal further reports.
