The firm, founded in 1885, has been consistently recognized in The American Lawyer's Am Law 200 rankings, climbing to No. 171 in the 2026 report and ranking among the fastest-growing law firms in the country by revenue growth. As of 2025, Fennemore is reported to have 342 attorneys.

The firm's intellectual property litigation practice handles a wide range of disputes, including patent, trademark, trade dress, copyright, licensing, trade secret misappropriation, and domain name disputes. Their litigators possess technological acumen to advocate for businesses and entrepreneurs in asserting and protecting their intellectual property rights. Specific technology areas covered by their practitioners include semiconductors, 3G/4G/5G standard-essential patents (SEPs), GPS navigation, medical devices, medical imaging, Wi-Fi router technology, online content and ads delivery, e-cigarette technologies, and solar cell manufacturing.

In its single tracked patent litigation matter, Fennemore represented the defendant. The firm acted as local counsel for COBRA Firing Systems, LLC and Phantom Fireworks Showroom LLC in Titan International Technologies, LTD v. COBRA Firing Systems, LLC et al., a case involving patents related to automated detonation of fireworks. While this specific tracked instance was defendant-side, the firm's broader IP litigation practice description indicates they advocate for clients in both asserting and protecting their intellectual property.

A notable outcome for the firm's patent litigation practice occurred in the Titan International Technologies case, where the court granted summary judgment for the defendants in July 2025, finding insufficient evidence of direct infringement. Titan International Technologies, LTD subsequently appealed this decision to the U.S. Court of Appeals for the Federal Circuit in April 2026. Fennemore also has a notable PTAB (Patent Trial and Appeal Board) practice, with attorneys like Chris Z. Liu possessing extensive experience in inter partes reviews (IPRs) for technologies such as e-cigarettes, map and GPS systems, security cameras, and solar cell manufacturing.

Key individuals in Fennemore's Intellectual Property practice include Eugene Pak, who serves as Chair, and Kathleen B. Carr, the Vice Chair. Chris Z. Liu, a Director in the Intellectual Property group, has extensive experience in district court patent litigations, inter partes reviews, ITC-337 investigations, and Federal Circuit appeals across a diverse technology spectrum. James E. Harper served as local counsel in the Titan International Technologies case.
