Massachusetts District Court

District of Massachusetts: Patent Litigation Profile

The United States District Court for the District of Massachusetts, located in Boston and sitting in the First Circuit, is a key venue for patent litigation, particularly given the Commonwealth's concentration of technology and life sciences companies. While historically not among the busiest patent venues in the nation, the court has taken significant steps to become a more attractive and efficient forum for patent disputes. Its docket often features cases involving sophisticated technologies, from biotechnology and pharmaceuticals to software and robotics.

The court's reputation in patent matters is increasingly defined by efficiency and predictability following a major overhaul of its local rules in 2018. Rejecting a reputation as a slow venue, the court implemented rules designed to bring cases to trial within 24 months of the initial scheduling conference. Prior to this change, the average time to a patent trial was significantly longer, around 37.6 months. The rules also expedite claim construction, mandating a Markman hearing within nine months of the scheduling conference. While some older analyses suggested the district was favorable to accused infringers, the 2018 rule changes were intended to provide a balanced and streamlined process for all parties.

Distinctive local procedures are central to patent practice in the District of Massachusetts. Local Rule 16.6, "Patent Proceedings," governs the management of all patent cases. This comprehensive rule establishes a series of mandatory, sequential disclosures that occur early in the case. The patentee must serve detailed infringement contentions just 21 days after the scheduling conference, followed by the accused infringer's non-infringement and invalidity contentions. Amending these preliminary disclosures is permitted only by leave of the court upon a showing of "good cause," a stricter standard than the more liberal amendment practice that preceded the rule change. This structured approach is intended to promote consistency, streamline discovery, and facilitate earlier resolution.

The district handles significant patent disputes, including the recently filed tracked case of SharkNinja Sales Co et al. v. Zhejiang Baili Technology Co Ltd, filed on April 20, 2026. The court has also been the venue for hard-fought intellectual property battles between major consumer robotics companies iRobot and SharkNinja. Judges in the district regularly issue substantive orders on claim construction and other patent-specific issues.

Several judges in the district have notable experience with patent cases. Former Chief Judge F. Dennis Saylor IV, now on senior status, utilizes a specific scheduling order template for patent cases that aligns with the local rules. Senior Judge William G. Young is also well-versed in patent matters, having presided over cases involving biotechnology, pharmaceuticals, and software. While Judge Young does not use a special patent-specific standing order, he is known for his active case management with a focus on moving cases efficiently to trial.
