HUPD Jan 2016 (local sample) with CPC/IPC taxonomy columns

Each classification symbol is of the form A01B 1/00 (which represents "hand tools"). The first letter represents the "section" consisting of a letter from A ("Human Necessities") to H ("Electricity"). Combined with a two digit number, it represents the "class" (class A01 represents "Agriculture; forestry; animal husbandry; trapping; fishing"). The final letter makes up the "subclass" (subclass A01B represents "Soil working in agriculture or forestry; parts, details, or accessories of agricultural machines or implements, in general"). The subclass is followed by a one-to-three-digit "group" number, an oblique stroke and a number of at least two digits representing a "main group" or "subgroup". A patent examiner assigns classification symbols to patent application or other document in accordance with classification rules, and generally at the most detailed level which is applicable to its conten

Added columns

For both CPC and IPC, we add semantic hierarchy columns derived from the compact string codes in HUPD:

• cpc, cpc-section, cpc-class, cpc-subclass, cpc-group, cpc-subgroup
• ipc, ipc-section, ipc-class, ipc-subclass, ipc-group, ipc-subgroup

Notes:

• HUPD stores compact strings (e.g. G06F30416) rather than A01B 1/00. We derive group/subgroup by splitting trailing digits as group_digits + last-two-digits subgroup_digits (e.g. 304/16).
