Non-patent anchors are simple, readily available ways to secure lines that don’t rely on patented hardware. A log fits this description because it’s a natural material used directly as an anchor without any patented design or device involved. In practice, logs are associated with basic, non-patented anchoring approaches suitable for temporary or low-load situations where manufactured hardware isn’t required.

Concrete, rock, and steel are common media used with engineered anchors and hardware that often involve patented designs or specialized components, so they aren’t categorized with the non-patent options in standard references.
