If you have used the apps like Facebook, and Sparrow on iOS then I don’t doubt your awareness of “Pull-to-Refresh” feature on them. This very feature is considered a handy one in apps having piles of user data.
A recent story on TechCrunch has revealed Twitter’s patent application for Pull-to-Refresh feature that the microblogging site filed back in 2010. The patent in the application is titled “User Interface Mechanics” that has been invented by Loren Brichter, the man who created Tweetie. The app was acquired by Twitter in the same year, 2010.
“Every large software company has large piles of patents, most of dubious merit. Most use them as a purely defensive measure,” said Paul Haddad, a member of the team who made TweetBot.
Twitter is yet to use this feature in its app.
