Challenges our approach Impact Solutions FAQs Get in touch The Challenges of Patent Data Quality Patent data is publicly available from 100+ authorities worldwide, but raw datasets often contain critical errors: Incomplete ownership information Subsidiaries, historic names, or inventors often appear in place of the true ultimate owner, hiding the real competitive landscape. Ambiguous legal status Patents may lapse, be reassigned, or invalidated long before their 20-year term, making it unclear who truly controls the rights. Name variations and translation errors Misspellings, transliterations, and homonyms lead to fragmented or duplicated ownership records. Relying on unharmonized data can result in misjudged valuations, flawed benchmarks, and billion-dollar missteps.
