Lightning talk presentation to WikiConference North America 2018

  • Wikidata can record basic information (not detailed information) about tens of millions of patents, someday. Right now there are only a few hundred.
  • Project's goal: set standards for patent data on Wikidata, and make it easy
  • The WikiProject Patents page: Wikidata's WikiProject Patents
  • Focus: patents from before 1923, because
    • They're beyond copyright
    • Their claims (almost?) never apply any more[1]
    • Patents were shorter and simpler back then
    • There are not as many: Fewer than 100K annually worldwide before 1910. The numbers grew exponentially. Now, 3 million a year.
    • This is relevant to my off-wiki research, tracking aero technology back then
  • I've begun a conversation with WIPO (World Intellectual Property Organization, the UN unit that manages the more recent treaty's relationships)

Patent data elements

  • Instance of (P31) A patent item should be an instance of either patent (Q253623) or U.S. Patent (Q43305660), perhaps both. That property is the one to query (search) that is unique to patents.
  • Page title -- one standard form: Patent US-1906-827017, Patent CA-1914-153820 -- different titles are fine too
  • Country where filed: Here are three options; freely use any or all. They express slightly different things
    • Use issued by (P2378) and identify the office to which the patent was filed -- e.g. US Patent and Trademark Office, Japan Patent office (JPO)
    • Or, "applies to jurisdiction" (P1001) and then the Q-id of the government; or, country (P17) and then the Q-id of the national government/country. The country may not still exist.
  • Filing date: Formal date of submission of the patent application, and generally speaking the date on which the patent goes into force legally once it's approved
  • Grant date: Certification by a government that the patent is accepted, and applies in the jurisdiction. (Might be more complicated with later international treaties.)
  • Applicant(s) -- there's always at least one ; can include company or university or government lab
  • Inventors: Zero or more; Might like to mark their order for some we have "author name strings", for others Q-ids (same for scientific publications)
  • Title: Applicants give a title in the language of t
  • Patent number -- inherited from years ago, e.g. US821393 -- works for those on google patents, and automatically links to that source
    • PROBLEM: too strict a format ; what to do for the ones that don't fit the format?
  • link to Wikisource if patent document is there
  • Link to Q-id or string of Parent patent or child patent ?
  • Assignee? Important in industrialization
  • Pointer to URL with more information, possibly the full text and diagrams -- There is not yet a site and covers the 19th century completely. Wikidata could be the best site for this, someday.

Possible good outcome from getting patents onto Wikdiata

  • We could add patent offices to the Authority Control line, maybe -- like USPTO, or WIPO, and if user clicks can get to a list of patents on Wikidata

  • Link together patents transcribed on Wikisource
  • Chart patent counts by inventor, country, tech topic; Time lines
  • Other insights?

  • Any input? How should this be done? What would be useful to you?
