Top Trademark Attorneys — Delaware
Attorneys with the most trademark registrations to their name for businesses incorporated in Delaware, by registration year. Updated with every data refresh.
What "Delaware" means on this page
A very large number of American companies incorporate in Delaware while operating elsewhere, so the owner address on their trademark filings is often a registered agent here rather than a place of business.
This list therefore ranks the attorneys filing most often for businesses incorporated in Delaware, not attorneys practising in Delaware or businesses trading here. Most of these attorneys are based in other states.
2026 is still in progress. Registrations continue to be issued through the year, so these counts will rise and the order may change. Completed years are shown for comparison.

How this list is compiled
TrademarkToolbox Top Trademark Attorney lists are not a ranking of attorney quality. Rank is based solely on the number of trademark registrations that list the attorney as attorney of record, for applications tied to businesses incorporated in Delaware. It measures filing volume, nothing else.
Volume reflects firm size, practice model and client mix. A solo practitioner handling a small number of complex matters will rank below a high-volume filing practice, and that says nothing about the quality of either. These lists are not an endorsement, a recommendation, or a substitute for your own due diligence when choosing counsel.
Data comes from USPTO public records as indexed by TrademarkToolbox. Attorney names are matched conservatively: we do not merge similar names, so an attorney who appears in the record under more than one form may be undercounted. Counts include registered marks only, by registration year. Full methodology · Request a correction or removal
