About Us

80 years of experience across 216 jurisdictions

Lysaght is an established intellectual property (‘IP’) registration law firm specialising in the formalities required for registering, maintaining and renewing trade marks, patents and designs. 

After almost 80 years in this industry, we have the specialist skills, expertise and worldwide relationships to offer our clients a first-class service.

We have fostered strong relationships and connections with local IP specialists in the jurisdictions of the world where we cannot act directly at the Registry, and we have worked with many of these agents for decades. Please visit our countries page to find out where we can register.

We are an independently owned private company and this allows us to make decisions quickly. The directors have all worked for the company for many years and have grown the business into what it is today. Whilst we are a small firm, we work with well known multi-national companies all over the world and we have held some of these relationships for many decades.

We want Lysaght to be an extension of your business and to be your trusted IP adviser. Our company values are at the heart of our culture and ethos, and they drive us everyday. They are: Putting People First, Collaboration, Reliability, Integrity and Attention to Detail. Our number one focus is how we treat people, both our clients and colleagues. We take inclusion and diversity very seriously and we are mindful of our responsibilities in this respect.

We are a friendly, hardworking and dedicated team who take great pride in helping our clients and we look forward to working together.
