Node area is scaled to amount. Form D reports securities sold, which can differ from an announced round; filings are numbered in the order they were made.
1 record has no date or no amount, so it isn’t placed on the timeline.

What it has protected
No granted patents are on record.
USPTO usually publishes applications 18 months after filing, so recent applications may not be visible yet. Patents assigned under a different entity name won’t match.
