Bronze - Firms: litigation

Neal Gerber & Eisenberg makes its first appearance in the IAM Patent 1000 this year, following significant growth and stellar client feedback. The firm provides both contentious and non-contentious support to patrons, managing large portfolios and defending IP rights in high-stakes litigation. Two familiar names in the guide are Jeffrey Ward and Emer Simic. “Jeffrey provides timely and insightful advice and is phenomenal to work with. He is an excellent lawyer and is extremely experienced in handling patent matters.” Simic is a strategic counsellor and a relentless advocate, with a particular focus on pharmaceutical matters, including litigation under the Hatch-Waxman Act. Making their debuts in 2023 are Thomas McDonough and Bradley Rademaker. “Thomas is a first-class lawyer with a very strong team. He is a highly knowledgeable and articulate expert, who develops a deep understanding of his clients’ portfolios and businesses. Thomas is thorough, pragmatic, quick to get up to speed and produces great results.” Rademaker is a deft portfolio manager who can also defend his patrons’ IP rights at trial. He handles a combination of patent and trade-secret briefs.

Firm Profile

Neal Gerber Eisenberg is one of the largest single-office law firms in the nation. It was founded in 1986 by a group of lawyers of widely diverse backgrounds and personalities. Entrepreneurial and independent-minded as individuals, these lawyers were committed to a firm culture and style of practice that encouraged collaboration among colleagues at all levels. Each of the founders brought to the enterprise years of experience in and deep substantive knowledge of specialised areas of law, yet each favoured practising in ways that were broadly interdisciplinary, recognising the fresh perspectives that approach could bring to every client matter. The firm has grown and thrived in large part because so many of our clients have been strongly entrepreneurial and individualistic and have seen their own values and outlooks mirrored in us.

Global leaders and cutting-edge start-ups alike trust the tenacious, problem-solving skills of our patent attorneys to protect, defend and monetise their key business products. Our team consists of 25 registered patent attorneys licensed to practise before the US Patent and Trademark Office, many of whom have significant patent trial experience. We combine our knowledge across practices to solve patent challenges with the insights and experience of skilled lawyers, scientists and engineers.

Patent prosecution and portfolio management

Biologics, electronics, mechanical devices, business technologies and software – we work across a multitude of industries to adeptly handle domestic and international patent counsel and prosecution. Corporate giants rely on our world-class IP and corporate experience to analyse their patent portfolios, identify business opportunities and generate revenue through patent licensing arrangements. Last year alone, we obtained 318 US patents and 216 international patents, providing global support and protection for our clients’ invaluable business assets.

We manage global and national patent portfolios for a diverse range of clients, including a top-ranked Fortune 500 company, a fast-food industry giant and an international manufacturer of audio products.

Patent litigation

From jury trials to favourable settlements and all points of contention in between, we strategically counsel and fiercely protect our clients in cases of patent infringement and related patent claims. Our trial attorneys have significant experience in district court litigation, appeals to the Court of Appeals for the Federal Circuit and inter partes proceedings before the Patent Trial and Appeal Board. We learn our clients’ business to provide strategic counselling and opinions to help them avoid litigation and manage their risk exposure where appropriate.

Patent opinions

Our patent professionals perform patent opinion work that helps our clients mitigate risk by avoiding potentially costly patent litigation. Because our patent attorneys and agents regularly prepare domestic and international patent applications across a wide array of technologies, including business methodologies, software, chemical processes, and electrical and mechanical devices, we are adept in our review of prior art searches and can accurately advise on patent eligibility, saving our clients' resources to hone patent applications that are more likely to be granted.

Our experience in patent prosecution also enables us to spot infirmities that may invalidate our client’s competitors’ patents and counsel clients on infringement matters, including preparing written opinions on right-to-use and the infringement, viability and validity of patents owned by our clients or their competitors. We help our clients make sound business-driven decisions by performing the due diligence needed to avoid obstacles and risks and to clear patents so that product production and launch can begin.
