Free patent databases: a practical 2026 guide

Start with keywords in Russian and English. Then inspect the applicant, family, priority, IPC/CPC and legal status. Save your query, date, relevant publications and reasons for relevance.

Our search directory opens Google Patents, Espacenet, PATENTSCOPE and national sources. Results are delivered by the selected database; outbound links are clearly identified.

The FreshDoc Habr collection was published in 2015. It inspired the directory; obsolete TESS, ROMARIN and OHIM links are not presented as current products. Patentability and freedom-to-operate require professional analysis of claims and territories.

The next stage is an EPO OPS integration with application registration, quotas and a source log. EPO currently offers up to 4 GB per week free of charge.
