Our firm began on January 1, 1967, when it was founded by Norman MacLachlan, a Chartered Patent Agent and Trade Mark Agent. Three years later he was joined by Frank Donaldson, also a Chartered Patent Agent with years of experience in London. In 1972 they cemented their partnership by officially creating MacLachlan & Donaldson.
Within a decade their partnership had grown to one of the largest Intellectual Property law firms in Ireland with the help of a reputation for delivering efficient and cost effective solutions for their clients. Strong personal relationships with clients combined with zealous professional advocacy have resulted in long standing partnerships.
For almost half a century from 1968, MacLachlan & Donaldson was based in the same historic area of Georgian Dublin that housed the Irish Patents Office for more than 70 years before it relocated in 1998. Situated opposite Merrion Square Park, this area is a hub of legal and professional services in Ireland.
Inspired by our place in the heart in Dublin, surrounded by other legal firms of long standing and just a stone’s throw from the Irish Parliament and other hubs of government, we adopted a Georgian door as our logo in 1987. And though the firm went through a rebranding in 2013 as we grew over time, that influence is still reflected in our current logo.
MacLachlan & Donaldson has grown many times over the years, always bringing in new faces with wide ranging expertise. In 1996 the firm acquired the IP practice of Dermot P Cummins & Co. and in 2002 acquired Ansons, one of Northern Ireland’s largest IP firms. This enables us to offer our services in all parts of the island of Ireland, particularly useful when businesses so often straddle the border.
In 2010 the firm evolved again, taking on limited company status. The next decade was one of ongoing change, as the firm moved first to new modern offices in Clonskeagh Square, Dublin 14, and then again to the Citywest Business Campus in 2018. Home to over 200 home grown businesses and world spanning companies, this is the perfect place for MacLachlan & Donaldson to continue to grow and thrive.
