With over 2,000 legal professionals worldwide, the firm is recognized as a BigLaw entity. Morgan Lewis consistently ranks highly, earning a Top 5 position on The American Lawyer's A-List from 2023 through 2026 and being ranked #37 in Vault's 2026-2027 Law 100. Chambers USA also recognized 155 of its practices and 333 lawyers in its 2026 edition, while The Legal 500 United States 2026 Guide acknowledged 66 practices and 289 lawyers.

The firm’s intellectual property litigation practice boasts extensive experience across diverse technology sectors. These include life sciences (pharmaceuticals, biologics, biotechnology, medical devices), general technology (semiconductors, consumer electronics, software, internet-based technologies, computer hardware, and artificial intelligence), as well as energy, financial services, and retail. Morgan Lewis handles patent cases in various forums, including US district courts, the US Court of Appeals for the Federal Circuit, the US Supreme Court, and the International Trade Commission (ITC). The firm represents both plaintiffs and defendants, asserting IP rights and defending clients against infringement claims, including those brought by non-practicing entities.

A notable case where Morgan Lewis served as lead counsel for the plaintiff, Netlist Inc. v. SK hynix, involved memory technology patents, including high-performance server memory. This dispute, which included an ITC investigation and parallel litigation, concluded in April 2021 with a comprehensive settlement. The agreement included a patent cross-license, a supply agreement, technical cooperation on CXL HybriDIMM technology, and a royalty payment to Netlist. While an ITC judge initially found infringement in October 2019, the full Commission later reversed this finding in April 2020 before the parties reached their settlement. Beyond this, the firm has secured defense verdicts for clients like LG Electronics in a smart TV patent dispute and lululemon against Nike.

Morgan Lewis possesses a significant practice in US Patent and Trademark Office (USPTO) post-grant proceedings, including inter partes reviews (IPRs) before the Patent Trial and Appeal Board (PTAB). The firm has a long history in this area, including arguing the second-ever IPR before the PTAB, and has achieved successful outcomes such as the dismissal of IPRs and Covered Business Method reviews. Managing IP's 2026 IP Stars guide ranks Morgan Lewis in Tier 3 for PTAB Litigation. Key partners in the IP litigation practice include Louis W. Beardell, Jr., who leads the global IP practice, Dion M. Bregman, recognized for his PTAB experience, Anita B. Polott, a go-to advisor for enforcement and litigation strategy, and Michael J. Lyons, who co-leads the Silicon Valley IP practice and represents technology companies in patent infringement matters.
