Lerner David Littenberg Krumholz & Mentlik LLP

Lerner David has been a globally renowned IP boutique for 50 years. While others folded their boutiques into large law firms, Lerner David has stayed true to its passion – teaming with clients to focus solely on building and protecting IP assets (ie, 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.

Post-grant proceedings

Lerner David’s post-grant practice has always been active, and expanded almost immediately with the passage of the America Invents Act. Whether used as an alternative or adjunct to district court litigation, our post-grant practice has the tools and experience to guide clients through any post-grant proceeding. We are adept at defending patents, as well as attacking patents in such proceedings.

ITC proceedings

Bolstered by technical acumen that is second to none, Lerner David has guided multinational clients in diverse industries and technologies through patent infringement matters with trade implications at 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

The firm’s expertise in selecting and registering trademarks worldwide is grounded in being integrated synergistically with marketing. Important in operating in today’s global economy, the firm has assisted clients in 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 IP due diligence

Lerner David’s procurement, litigation and licensing experience provides the skillset 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 acquired intellectual property and products, Lerner David continues to add value post-closing.

Clearance opinions

IP roadblocks can undermine the development, acquisition and ultimate 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 and efforts in establishing robust due diligence programmes has resulted in far less litigation for clients who invest in such programmes.
