Harrity & Harrity LLP

Harrity & Harrity is one of the United States’ leading patent preparation and prosecution firms specialising in the electrical and mechanical technology areas, and is considered a go-to firm for the Patent 300. Our services include patent preparation and prosecution, patent analytics, client counselling and opinions and IP strategy. Since our inception, Harrity & Harrity has grown and maintained a robust and prestigious client base, including eight Patent 300 companies and some of the leading technology companies in the world. Our client base consists mainly of long-term clients, which have come to trust and depend on our quality, experience, innovation and service.


Quality is the area that truly separates us from our peers. Our firm prides itself on consistently delivering high-quality services by using a thorough second attorney review process and a uniform writing style that is tailored to clients’ guidelines. The second attorney review process ensures that all work produced is of the highest quality before it is sent to clients for review. Therefore, two patent professionals are intimately involved in each client matter. Our second attorney review is performed by our Harrity review team, which includes partners and attorneys with more than 20 years’ experience. Our uniform writing style ensures that clients receive a consistent work product from our firm. At Harrity & Harrity, we say that “we patented quality”, and our second attorney review and uniform writing style ensure that we provide clients with the highest-quality patent preparation and prosecution services each and every time.


Our people are another area that makes us stand out. Our team of attorneys averages more than 15 years’ experience in the patent field. Nearly 40% of our attorneys – including 100% of the firm’s partners – are former patent examiners. In addition, 100% of our attorneys are registered to practise before the USPTO. Our attorneys have technical backgrounds in electrical engineering, computer science, mechanical engineering, physics, industrial and systems engineering and civil engineering. In effect, we can handle any invention in the electrical or mechanical arts. Harrity & Harrity is considered to be a medium-sized firm – that said, we perform a large volume of work. From 2016 to 2018 we drafted more than 2,000 patent applications and obtained nearly 2,000 allowances on behalf of clients.


Innovation is yet another area of expertise. At Harrity & Harrity, we strive for excellence, so we track a large number of statistics in order to measure our performance and improve the services that we provide to clients. We also share our statistics with clients to ensure that they know exactly how we are doing, performance-wise. We provide a level of transparency that is unparalleled in the patent field. In addition to statistics tracking, we have developed a massive proprietary database that we use to make intelligent prosecution decisions and analyse the patent landscape for clients. Our patent analytics group provides our clients with decision-making insights into their own portfolio, their competitors’ portfolios and law firms. In addition, we have developed industry-leading software tools that improve the quality and uniformity of our work products.


Client service means everything at our firm. We believe in partnering with our clients to ensure that we provide outstanding service. We strive to raise the expectations that our clients have for their firms by helping them to understand their own patent portfolios, by saving them time and money and by acting as though their patent portfolios are our own
