Another “patent troll” defeated by Cloudflare and its army of bounty seekers

As soon as once more, Cloudflare has confirmed that its uncommon protection in opposition to meritless patent infringement claims successfully works to finish so-called “patent trolling.”

In a weblog publish, Cloudflare introduced that its most up-to-date victory—defeating a lawsuit filed by Sable IP and Sable Networks in 2021—was largely because of contributors of Challenge Jengo. Launched in 2017, Cloudflare’s program affords tens of hundreds of {dollars} in awards to activate a military of bounty seekers and crowdsource submissions of proof—referred to as “prior artwork”—that can be utilized to beat frivolous patent claims and even invalidate patents that by no means ought to have been issued.

To seek out prior artwork, Challenge Jengo contributors comb by educational papers, technical web sites, and patent paperwork, serving to Cloudflare clarify in detailed petitions to the US Patent and Trademark Workplace (USPTO) why sure patents must be invalidated.

Sable’s lawsuit alleged that Cloudflare had infringed patents filed “across the flip of the century” addressing “hardware-based router expertise of the day,” Cloudflare stated. At that time, it was as much as Cloudflare to persuade a jury of maybe not probably the most technically proficient friends that this router expertise had nothing to do with Cloudflare’s “modern-day software-defined providers delivered on the cloud.”

“Patent trolls create what we think about to be an unfair, unjust, and inefficient system that throttles innovation and threatens rising corporations,” Cloudflare CEO Matthew Prince advised Ars. Whereas different corporations usually settle with “patent trolls” to keep away from pricey authorized battles that may drain vital assets in any other case funding improvements, Prince stated that Cloudflare’s most up-to-date victory is “an essential validation that we will efficiently struggle again in opposition to the menace to innovation posed by patent trolls.”

To defeat Sable, Cloudflare supplied $100,000 “to be break up amongst winners that submitted robust prior artwork.” Responding, Challenge Jengo contributors spent three years monitoring down dozens of submissions of prior artwork. Via these efforts, Sable’s lawsuit—which initially “asserted round 100 claims spanning 4 patents in opposition to a number of Cloudflare merchandise and options,” Cloudflare stated—was impressively narrowed to “a single asserted declare on a single patent.”

Even defending itself in opposition to one declare left Cloudflare in a troublesome place, although. The corporate nonetheless wanted to persuade the jury that this one declare was meritless, or else the jury might award Sable doubtlessly giant damages just because they failed to grasp the complicated applied sciences concerned.

“Taking a case to trial—even on easy issues—is extraordinarily pricey,” Cloudflare’s weblog stated. “In patent instances, which means hundreds of thousands of {dollars}.”

This threat is exactly the explanation why “patent trolls” file claims, sometimes buying “rights to the patents of a failed {hardware} firm” and searching for to “monetize” patents “to the best extent attainable,” Cloudflare defined. Seemingly using this technique, Sable had efficiently secured settlements from a number of corporations earlier than, together with Cisco, Fortinet, Test Level, SonicWall, and Juniper Networks. In 2021, Sable focused Cloudflare, possible hoping for an additional settlement exterior of courtroom.

“If that meant leveraging a patent associated to decades-old router {hardware} to sue a cloud-based service supplier, so be it,” Cloudflare’s weblog stated. “And if it required leaps of logic and untethered claims that may make a toddler blush, oh nicely.”

Sable’s legal professionals didn’t reply to Ars’ request to remark.

In courtroom, pointing to prior artwork and sharing a Cloudflare engineer’s experience, the Cloudflare authorized workforce broke down for the jury “the numerous the reason why” Sable’s patent “doesn’t describe something that Cloudflare really does.”

It took a jury two hours to resolve that Cloudflare was proper, not simply dismissing Sable’s claims however invalidating Sable’s patent completely as a result of prior artwork confirmed that “Sable’s patent coated, at greatest, solely expertise that had already been described by inventors at Nortel Networks and Lucent Applied sciences—main routing expertise corporations on the time.”

To this point, Cloudflare has awarded $70,000 to Challenge Jengo contributors who helped the corporate defeat Sable. In line with Cloudflare’s weblog, the corporate will announce the ultimate $30,000 in awards after the “official conclusion of the case.”

Cloudflare additionally plans to share “extra ideas and insights we’ve gleaned from going through down a troll at trial” to assist different corporations which might be contemplating taking up “patent trolls.”

Challenge Jengo’s first success got here in 2019 when Cloudflare defeated Blackbird Applied sciences. Because of that victory, Blackbird “went out of enterprise,” successfully ending that firm’s meritless patent infringement claims, Cloudflare stated. Now, Cloudflare has “invalidated important elements of three Sable patents, hamstringing their skill to convey lawsuits in opposition to different corporations,” Cloudflare stated.

Due to the mission’s success, Prince advised Ars that Cloudflare would proceed awarding “hundreds of {dollars} in bounties” to discourage patent trolling by Challenge Jengo. With two wins beneath this system’s belt, Cloudflare hopes the Sable verdict serves as “a powerful warning to all patent trolls—we won’t be intimidated into taking part in your recreation.”
