IPRATE

Who Are the Best Trademark Firms in Greece? (2026)

IPRATE analysed 2,371 firms across 23,290 EU (EUIPO) trademark filings in Greece; 231 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 trademark firms in Greece

This table compares EU (EUIPO) 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 experience with the goods and services your brand covers, then discuss clearance, filing and portfolio management. 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.
