Today, Google pledged that it will not sue any users, distributors or developers who have implemented versions of its patented MapReduce programming model. Google took out an Open Patent Non-Assertion (OPN) Pledge, which states that they will not take legal action against distributors and developers of open-source software.

Google has countersued British Telecom, a multinational telecommunications company based in the United Kingdom, with a new patent infringement lawsuit filed in the U.S. and the U.K. BT first took legal action against Google back in 2011, but Google has called its complaint “meritless,” and accuses the company of “arming patent trolls.”

The European Commission’s Vice President for Competition Policy, Joaquín Almunia, has confirmed that it will charge Samsung “very soon” in an antitrust patent case after the Korean electronics giant broke competition rules by filing patent-infringement lawsuits against Apple. Samsung has been under investigation since January for a possible breach of antitrust rules, and earlier this week, it dropped all of its injunction requests against Apple in Europe.

Korean electronics giant Samsung has today announced that it will drop its patent-infringement lawsuits against Apple in Germany, France, Italy, the Netherlands, and the United Kingdom. The announcement comes just hours after Apple was denied its request to have 26 Samsung devices banned in the United States — though the two cases are unrelated.

A mere ten days before the scheduled patent infringement trial between Samsung and Apple, US District Judge Lucky Koh rejected two more proposals from Samsung, maker of Android enabled smartphones. Judge Koh entered a supplemental claim construction order in which two disputed terms are now defined. Unfortunately for Samsung, who initially requested the order, the definition decision favors Apple, using the Cupertino-based tech company’s definition in the dispute.
