We specialize in Trademarks, Patents, Copyrights and related IP Rights.
At Castrillo & Castrillo we manage our client’s needs from start to finish; from the ideas process to drafting agreements; from protecting these assets, to providing support in filing, prosecution, litigation and seeking damages as well as dispute resolution and settlement.
OUR MAIN PRACTICES
WHAT SETS US APART
Trademark watch
We review the entire INPI Trademark Gazette, every week: every published application, not a sample. Composite and figurative marks included, reading the wording that sits inside the logo — more than half of what is published in Argentina, and invisible to a watch that only searches text.
Portfolio custody
Renewals, mid-term declarations of use and office-action deadlines, with advance notice and follow-up through to closing. The owner hears about it before, not after.
Domain name watch
Daily monitoring of .ar registrations to detect domain names confusingly similar to our clients’ trademarks.
Trademark filing and enforcement
Clearance searches verified file by file against the INPI, with analysis of the exact coverage of each prior right and of its actual use in the market. Filings, oppositions, office-action replies, renewals and assignments.
Patents and utility models
Filing, prosecution and replies to substantive examination, with the cited prior art checked document by document.
Copyright, domain names and agreements
Registration of works, software and databases. Licence, confidentiality and technology transfer agreements.
