Lerner David Littenberg Krumholz & Mentlik LLP

Lerner David has been a globally renowned IP boutique for 50 years. While other boutiques sold out to large law firms, Lerner David has stayed true to its passion – teaming with clients to focus solely on building and protecting IP assets (patents, copyright and trademarks). Grounded in exceptionally high standards of professionalism, integrity and character, the firm’s attorneys and paralegals are highly sophisticated and committed to this mission.

Having a reputation for effecting positive results for its clients – in patent and trademark offices, in court and at the bargaining table – it is the firm’s role as counsellors that remains paramount. It is the firm’s sound, practical advice that helps clients make informed decisions. Coupling a business-oriented approach with a broad international reach, Lerner David has succeeded in fostering long-term relationships with its clients.

IP litigation

“When we need someone to really dig in and fight a good fight, we typically turn to Lerner David.” This Fortune 100 client recognised our firm’s focus on detail and achieving business goals. Our experience in technology and IP procurement enables the firm to readily distil complex information and present creative legal arguments, such that the arbiter is more apt to embrace our positions. In 2015-2020 the New Jersey Law Journal named Lerner David as the winner of its Intellectual Property Litigation Department of the Year award.

Post-grant proceedings (inter partes reviews)

Lerner David’s post-grant practice has always been active. Whether used as an alternative or adjunct to district court litigation, defending or attacking patents, we have the tools and experience to guide clients through any post-grant proceeding.

ITC proceedings

Lerner David’s foundation in technology and litigation has enabled it to swiftly navigate the complexities in Section 337 investigations. Lerner David has guided multinational clients in diverse industries and technologies before the ITC. Our lawyers have served as lead trial counsel for both complainants and respondents at the ITC, and have also acted as shadow or monitoring counsel on many other investigations.

Patent procurement

Our attorneys team up with clients to parlay critical inventive features into solid IP assets. The firm’s keen understanding of technology, Patent Office proceedings, licensing and litigation enables it to build portfolios with real-world value. Efficiencies are realised given our investment in a contemporary infrastructure and in our pool of talented paralegals.

Trademark procurement

Important for operating in today’s global economy, the firm has assisted clients with the selection of brands to be used around the world. This requires not only an understanding of different laws and legal systems, but also sensitivity to cultural implications of brands in different countries and regions.

M&A diligence

Lerner David’s full-service IP practice supports the skillset needed to measure and manage risk in product and technology acquisition. Focusing on the quality of a target’s intellectual property, as well as potential infringement risks, Lerner David provides valuable input to the M&A team. Having the foresight to visualise and plan the all-important integration of the target intellectual property and products, Lerner David adds value before and after closing.

Clearance opinions

IP roadblocks can undermine the development, acquisition and success of a product. The firm’s clearance efforts lead to written opinions for business guidance, as well as the development of potential ‘design arounds’ that best position the product. Our experience in establishing robust due diligence programmes has resulted in far less litigation for our clients.

Privacy and data

Lerner David leverages its technology expertise to navigate through an evolving and complex array of global requirements governing the privacy landscape. We assist clients in high technology areas assess and implement the compliance framework required for privacy and data management in today’s fast-moving business environment.
