An anonymous Slashdot reader writes: Remember that patent lawsuit filed against GNOME's Shotwell in 2019? An enterprising open source lawyer has challenged it within the patent office and gotten the whole thing canceled!

The decision by the U.S. patent office may give patent troll cause to steer clear of open source projects, even more than the fierce resistance the community impressively funded and mounted in the GNOME case. That is what the founder of OSI sponsor LexPan Law did. Smith pointed out in his re-examination request that the patent was not for a new invention. They agreed. The part of a patent describing what the patent rights cover has been canceled. The Rothschild patent cannot be used against open source projects. The victims of the attacks after GNOME have little comfort in the fact that many of the companies targeted with related patents have yet to be re-examined. It is good to know that there are open source advocates of all sizes.
