Andrew M. Dufresne

Based on available information, Andrew M. Dufresne is an attorney with Michael Best & Friedrich. His patent litigation experience includes serving as local counsel for the plaintiff, Rare Breed Triggers Inc., in a case against Orion Arms Corp. The subject matter of this litigation appears to involve mechanical devices in the firearms sector.

The authoritative case data shows Mr. Dufresne representing the plaintiff's side in his single tracked appearance. Beyond this case, further information regarding his specific practice focus, client base, or potential experience before the Patent Trial and Appeal Board (PTAB) is not available in publicly accessible sources. His educational background and bar admissions are not specified in legal directories or the firm's public materials.

It is worth noting that a different patent attorney, Andrew T. Dufresne (with a middle initial "T"), also has a professional history with Michael Best & Friedrich but is now affiliated with another firm. Care should be taken to avoid conflating the professional records of the two individuals.
