Farrell & Reilley

Farrell & Reilley's patent litigation practice, as indicated by available tracking data, appears to be a highly specialized legal entity. Due to the firm's specific name, detailed public information regarding its headquarters, full office footprint, and overall firm size (such as an AmLaw or Chambers ranking) is not readily available through public web searches. As such, it is not possible to definitively classify it as BigLaw, an IP boutique, or a regional patent shop without further verified data.

Based on the single tracked case, Angiodynamics Inc v. Endovascular Engineering Inc, the firm demonstrates involvement in patent disputes within the medical device technology sector. The case, filed in April 2026, concerns alleged infringement of patents related to self-expanding funnel technology used in thrombectomy systems. This suggests an IP litigation specialty in complex mechanical or medical technology, particularly devices designed for use within the human body.

The firm's participation in tracked cases indicates a clear preference for defending clients. Farrell & Reilley has appeared solely on the defendant side in the single tracked matter, where it is listed as lead counsel. There are no recorded appearances for the firm on the plaintiff side.

The most prominent tracked case is Angiodynamics Inc v. Endovascular Engineering Inc, currently pending in the U.S. District Court for the District of Delaware. In this matter, Farrell & Reilley is representing Endovascular Engineering Inc. against patent infringement allegations brought by Angiodynamics, Inc.. The outcome of this recently filed litigation is not yet public.

Information regarding Farrell & Reilley's involvement in Patent Trial and Appeal Board (PTAB) or Inter Partes Review (IPR) proceedings is not publicly available or reflected in the provided data. Therefore, the scale or nature of any such practice cannot be ascertained. Key partners identified from the tracked case are Stephen J. Farrell and Lewis C. Farrell, who are listed as top attorneys and have served as lead counsel in the firm's tracked patent litigation.
