Blank Rome is an Am Law 100 firm, headquartered in Philadelphia, Pennsylvania, with 16 offices across the United States and one in Shanghai, China. The firm is a large, full-service legal provider, employing between 750 and 800 attorneys. It is consistently recognized among the top law firms nationally, including in The American Lawyer's surveys for midlevel associate satisfaction.

Blank Rome's intellectual property litigation practice boasts extensive experience across diverse technology areas. The firm handles complex patent disputes in fields such as biotechnology, pharmaceuticals, computer hardware and networking, software, data processing, telecommunications, automotive, chemicals, manufacturing, semiconductors, petroleum services, and nanotechnology. This is evidenced by their work for clients like Bose Corp in a plaintiff-side matter and defending TomTom, Inc. in patent litigation.

The firm's patent litigation practice operates on both the enforcement and defense sides, representing both plaintiffs and defendants. Over the past five years, Blank Rome has handled more than 430 infringement suits and declaratory judgment actions. Notable outcomes include securing an early summary judgment for Oshkosh Corporation in 2020 in a patent infringement suit related to armored vehicles, and a summary judgment for Daktronics in 2018, dismissing a willful infringement claim concerning a theatrical winch patent. More recently, in 2024, the firm obtained multiple favorable U.S. International Trade Commission (ITC) initial determinations for Efficient Power Conversion (EPC), finding key gallium nitride (GaN) related patents valid and one foundational patent infringed. The firm also contributed to a significant Federal Circuit decision in Lashify v. ITC in 2025, which may impact ITC intellectual property cases.
