Leahy Delays Markup of Patent Bill Companies Oppose [Getty Images]

The U.S. Patent and Trademark Office (USPTO) seal is displayed inside the headquarters in Alexandria, Virginia, U.S., on Friday, April 4, 2014. The Senate Judiciary Committee tomorrow plans to mark up a measure that would curb the activities of so-called patent trolls after pulling back the bill last week in the face of opposition from such companies as 3M Co., AstraZeneca Plc, Monsanto Co. and Procter & Gamble Co.
