'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! OpenSource.org argues that decision by the U.S. patent office "may well give patent trolls cause to steer clear of open source projects — even more than the fierce resistance the community impressively funded and mounted in the GNOME case." Of the many methods developed over the past 20 years to eliminate patent threats against FOSS, none is as powerful as challenging the nefarious patents directly. That's what McCoy Smith, founder of OSI sponsor LexPan Law, did.... Smith pointed out in a re-examination request to the U.S. Patent & Trademark Office that the patent was not for any new invention. They agreed. As a result, all of these "claims" in the Rothschild '086 Patent — the part of a patent describing what the patent rights cover — have consequently been canceled. The Rothschild '086 patent can no longer be used against any victim, including open source projects. Of course, that's little comfort to the 20+ victims attacked after GNOME with the now-proven-worthless Rothschild '086 patent, or the 50+ companies targeted with related patents that haven't yet been re-examined.... Still, it's good to know there are open source champions of all sizes defending the development of open software.' -- source: https://yro.slashdot.org/story/22/05/08/0052226 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/
