+Subpatents are a system introduced in 1919 NE by the Western Sector
+government to allow companies to easily license the rights to patents
+as if they owned the patent.
+
+Subpatent names are formatted as `IMPORTANCE-SECTOR-SECTIONS-NUMBER`.
+
+`IMPORTANCE` may be one of:
+
+- `V` / Vital :: Important in all circumstances
+- `E` / Essential :: Important during galaxy-wide emergency
+- `N` / Normal :: Important during shortages
+- `X` / Extraneous :: Not vital in any circumstance
+
+`SECTOR` may be the abbreviation of any sector. Common are `E` and `W`
+for East and West.
+
+`SECTIONS` is a `/` separated list of sections, which may be:
+
+- `FO` :: Flooring
+- `MA` :: Materials
+
+`NUMBER` is the number of the subpatent, which is a linearly
+increasing integer starting at 1. The number is used to discriminate
+subpatents with the same importance/sector/sections fields.
