Patrick v0.4.0

[0.4.0] - 2026-06-17

This release grounds Patrick in real prior art and real law: he can pull the full
text of publications and cited documents, recall EPC provisions, the Guidelines,
and the case law verbatim, search that law when he doesn't have the citation, and
read scanned PDFs.

Added

• Prior-art retrieval. Ask Patrick for an EP or WO publication and he fetches
  its full text from the EPO's Open Patent Services; any other publication is
  retrieved via Google Patents — so cited documents and prior art come into the
  chat without you fetching and pasting them.
• Verbatim law recall. Tag a provision with / (e.g. /Article 54) and
  Patrick retrieves its exact wording rather than reciting from memory, shown in
  a dedicated provision card with its source. Recall covers the EPC, the EPO
  Guidelines for Examination, the PCT-EPO Guidelines, and the Case Law of the
  Boards of Appeal.
• Find the law. Describe a point of law or practice and Patrick finds the
  most relevant Guidelines and case-law sections for you, then retrieves their
  verbatim text — discovery when you don't already know the citation.
• Web search. Patrick can research law and practice he can't recall, with a
  toggle in the chat toolbar to turn it on or off per chat.
• Selectable, searchable PDFs. The PDF viewer now has a real text layer you
  can select and copy. Scanned (image-only) PDFs are run through on-device OCR so
  they become selectable too, and you can choose per PDF whether Patrick reads the
  original image or the cheaper extracted text.

Changed

• The / law picker is now grouped (EPC / Guidelines / PCT Guidelines / Case
  Law) and searchable by section title, not just citation.
• Underlying dependencies refreshed across the app.

Fixed

• A web-search citation no longer shows its source domain twice.
