Reichman Jorgensen Lehman & Feldberg

Reichman Jorgensen Lehman & Feldberg LLP (RJLF) is an elite national trial boutique specializing in high-stakes intellectual property and commercial litigation, with a particular focus on patent disputes. Headquartered in Redwood Shores, California (Silicon Valley), the firm maintains additional offices in New York, Washington D.C., Atlanta, and Austin. Founded in 2018, RJLF has been recognized as a "Top Trial Boutique" and an "Elite Boutique" by Benchmark Litigation and The National Law Journal, respectively. The firm comprises approximately 39 lawyers, including 15 partners, as of October 2025.

RJLF's patent litigation practice covers a broad array of complex technical fields. The firm's attorneys possess advanced technical degrees and expertise in areas such as electrical engineering, physics, computer science, computer networks, and biotechnology. Their case experience demonstrates proficiency in software, cloud computing, data storage, wireless standards (including 802.11), telecommunications, consumer electronics, virtualization technology, and cryptographic methods fundamental to blockchain and cryptocurrency transactions.

The firm frequently engages in plaintiff-side patent assertion, evident from 9 out of its 13 tracked appearances being on behalf of plaintiffs. RJLF represents innovators and companies seeking to enforce their intellectual property rights against larger technology enterprises. Notable plaintiff-side victories include securing a landmark $673 million award (including interest) for Kove IO against Amazon Web Services for cloud storage technology, following a $525 million jury verdict in 2024, which was the largest patent win of the year. The firm also obtained a $236 million patent infringement verdict for Densify against VMware for virtualization technology and a $15 million verdict (totaling $27 million with interest post-trial) for Droplets against Yahoo for browser technology. RJLF currently represents Malikie Innovations Limited in multiple suits concerning cryptographic methods for blockchain/cryptocurrency and 802.11 wireless standard-essential patents (SEPs). While predominantly plaintiff-focused, the firm also handles defendant-side engagements, such as representing CardWare Inc. against patent challenges.

RJLF is actively involved in proceedings before the Patent Trial and Appeal Board (PTAB). The firm has defended CardWare Inc. in multiple Inter Partes Review (IPR) proceedings, including Unified Patents v. CardWare Inc. and Google LLC v. CardWare Inc. (IPR2025-01344, IPR2025-01361). This demonstrates the firm's capability in navigating post-grant review challenges in addition to district court litigation. Christine Lehman, a managing partner, also brings significant experience in U.S. International Trade Commission (ITC) Section 337 investigations, which often parallel PTAB and district court patent disputes.

Key partners leading the firm's IP litigation practice include Courtland L. Reichman, a Managing Partner recognized for his ability to connect with juries in high-stakes patent, copyright, and trademark disputes. Christine Lehman, Managing Partner of the D.C. office, is an accomplished trial attorney with extensive experience in patent litigation and ITC matters. Khue V. Hoang, Managing Partner of the New York office and a former semiconductor engineer, focuses on complex IP challenges across various technology sectors, including telecommunications and consumer electronics. Matthew G. Berkowitz is also a prominent IP litigation partner, recognized by Chambers USA.
