Cloudflare defeats a second “patent troll”, invalidating parts of three Sable Networks' patents after crowdsourcing prior art findings through Project Jengo
Brandon Vigliarolo / The Register :
Context & Ripple Effects
Cloudflare had previously turned a Sable Networks lawsuit into a public search for earlier technical disclosures, offering a $100,000 prior-art bounty through Project Jengo. The effort extended the company’s earlier playbook after its Blackbird patent case was dismissed and the patent invalidated.
This outcome matters because it converts crowdsourced evidence from a defensive tactic into a result that weakens multiple asserted patents, rather than resolving only a single claim against Cloudflare.
First-order effects
- Parts of three Sable Networks patents are invalidated, reducing the patent portfolio Sable can use in its dispute with Cloudflare.
- Cloudflare gains a second documented win using an aggressive prior-art strategy, with Project Jengo contributors directly validated as part of its defense effort.
Second-order effects
- Other companies facing similar assertions have a clearer example of using public prior-art searches to supplement conventional patent litigation defense.
- Patent assertion firms relying on broad or weakly supported claims face greater pressure to test their patents’ validity before pursuing targets that can mobilize public technical communities.
Third-order effects
- If repeatable, crowdsourced prior-art research could shift some patent-defense leverage toward operating companies with large developer and user networks, lowering the isolation of individual defendants.
- The approach may make validity challenges a more central competitive response to patent assertions, though its effectiveness will depend on the quality of public evidence and court review in each case.
The trend: This is part of a broader shift toward technology companies using open, community-backed evidence gathering to challenge patent assertions at their source.
