IPRATE analysed 59 firms across 696 European (EPO) patent filings in Bulgaria; 14 firms met the evidence thresholds and are ranked below (Top Rated is the top quarter, every other firm is Rated). Based on official EUIPO, EPO and national IP office records. Ratings are never sold or sponsored.
Comparing patent firms in Bulgaria
This table compares European (EPO) filing records for the country shown. Start with the rating tier, then compare annual filing volume, outcomes and confidence on each firm profile. Compare like-for-like practices and periods: a high success rate on a small record is different evidence from the same rate across a large portfolio.
Compare the firm's technical subject areas and filing experience, then discuss drafting, prosecution and the jurisdictions you need. Use the published record to build a shortlist and confirm the fit with the firm. Filing outcomes describe the measured work; they do not establish litigation experience or predict the outcome of your case.
