The UPRP API for trademark search

The Urząd Patentowy Rzeczypospolitej Polskiej (UPRP) — the Patent Office of the Republic of Poland — is Poland's national industrial property authority, headquartered in Warsaw and operating as an independent agency under the Council of Ministers. Established on 28 December 1918 just weeks after Poland regained independence, UPRP is one of the oldest continuously operating IP offices in Europe. It examines and registers Polish national trademarks, patents, utility models, industrial designs, and geographical indications under the Industrial Property Law of 30 June 2000 (Prawo własności przemysłowej), the statute that consolidated Polish IP law and aligned it with EU directives ahead of Poland's 2004 EU accession.

As the IP office of the largest economy in Central and Eastern Europe, UPRP receives a meaningful national filing flow — 14,356 direct national trademark applications in 2024, up 6.4% year over year, on top of Madrid Protocol designations of Poland that route through WIPO. Poland acceded to the Madrid Protocol on 4 March 1997, so brand owners targeting Poland can either file directly at UPRP under the Industrial Property Law or designate Poland through a Madrid international registration. Many multi-country filers also rely on EU trademarks at EUIPO, which cover Poland alongside the other 26 EU member states through a single registration — UPRP national filings exist for Poland-only protection, earlier Polish seniority dates, or cases where EU-wide prior rights would block a wider EUTM.

UPRP exposes its register through the PUEUP Electronic Services Platform launched in 2020 and the e-Search (e-Wyszukiwarka) module at ewyszukiwarka.pue.uprp.gov.pl, which consolidates trademarks, patents, utility models, industrial designs, and the BUP (Patent Office Bulletin) and WUP (Patent Office News) gazettes in one searchable surface. The office has also stood up a bibliographic API endpoint serving BUP and WUP publication data plus a separate Authority File endpoint, replacing manual data preparation for downstream consumers. The catch is that everything is published in Polish — examination, opposition, and gazettes use Polish-language status vocabulary with full diacritics (ą, ć, ę, ł, ń, ó, ś, ź, ż), application numbers use the Z-prefixed format (Z.123456) while registrations switch to R.123456, and the three-month opposition window from BUP publication uses Polish procedural terminology. Signa is building its UPRP connector against e-Search, the PUEUP API endpoints, and the BUP/WUP gazettes for Q4 2026; on launch it will normalize the Polish register and Madrid designations of Poland into the same unified schema used for USPTO, EUIPO, DPMA, and every other office.
