L02-TS: Yes
Rationale
Tailscale Inc. publishes an explicit royalty-free patent grant for necessarily infringed claims under its control in its distributed implementation.
Assessment method
Official documentation and pinned source/declaration review; no runtime test
Source context
Tailscale identity documentation, LocalAPI and PATENTS grant
Outstanding qualification
Holder-bounded implementation grant, admitted by the same L02 rule as other implementation grants. It excludes claims arising only from further modification and terminates upon specified patent litigation. It does not cover arbitrary independent reimplementations, unpublished service code, third-party patents, or service subscription charges; no enforceability or patent-clearance opinion.
