Twitter Reassures Developers They Will Not Go After Companies Over Pull-To-Refresh Patent

Posted Apr 17, 2012

Twitter has reassured developers and designers that they will never pursue other companies that use their “pull-to-refresh” feature that they have patented. I have seen this feature used on apps like Facebook and the mobile web browser version of Gmail. Twitter also announced the ?Innovator?s Patent Agreement,” which assures that they will not use their patents against competitors.

?The IPA is a new way to do patent assignment that keeps control in the hands of engineers and designers. It is a commitment from Twitter to our employees that patents can only be used for defensive purposes. We will not use the patents from employees? inventions in offensive litigation without their permission. What?s more, this control flows with the patents, so if we sold them to others, they could only use them as the inventor intended,? said Twitter in a blog post.
