Case updates: Another patent thrown out of the case, and the few remaining claims further whittled down
When Sable sued us almost two years ago in March 2021, they accused us of infringing four different patents, which included a total of 134 claims. We previously shared how we successfully killed off one of the four patents, known as the ’932 patent.
Today, we have more great news to share. The U.S. Patent Office agreed with us that all the claims from the ’593 patent that Sable asserted against us are invalid. This means we were able to get yet another patent – the ’593 patent – dropped out of Sable’s case against us.
A single U.S. patent usually has somewhere around 10 to 20 claims (here’s a Wiki page explaining what a “claim” is in patents), but Sable’s ’593 patent included a whopping number of claims – 44 to be exact. As we previously shared back in January 2022, the Patent Office ruled that we would likely be successful in invalidating all 44 claims of the ’593 patent and instituted a trial proceeding known as inter partes review (IPR). Since then, Sable voluntarily canceled 17 of the claims – presumably because they themselves knew those claims were invalid. Of the remaining 27 claims, the Patent Office determined that 23 claims were invalid. Because none of the four surviving claims – which escaped invalidation only by virtue of a procedural technicality – are part of Sable’s case against us, the ’593 patent is no longer asserted against us. And given the record we have established before the Patent Office, we don’t think Sable will try asserting those four surviving claims from the ’593 patent against any of our peer companies. But even if Sable does, they should be able to leverage what we’ve done and kill off the patent completely.
Our victory was covered by multiple legal news outlets such as Bloomberg Law and Law360 (unfortunately, subscription required). A special shoutout to our attorney Jim Day of Farella Braun + Martel, who fought hard to get rid of these toxic claims that should have never been issued! With two patents completely out of the case, there are now only two patents at issue in Sable’s case against us.
We have even more good news to share! In October 2022, the Court found nine claims from one of the two remaining patents – the ’431 patent – to be invalid for failure to meet certain statutory requirements. This means Sable only has 14 claims from two patents in the case. Considering that we started this journey with Sable asserting 131 claims from four patents against us, we are proud of what we have accomplished thus far. We successfully persuaded the Court and the Patent Office to cancel, or forced Sable to voluntarily cancel, almost 90% of those 131 claims. Those victories not only help us in our case against Sable, they will also protect all innovative companies from being accused frivolously of infringing those invalid claims.
Our trial is scheduled for November 2023, but we will have more updates for you before then. Stay tuned, and remember to go look for prior art references to help us in our fight against this patent troll!
