About me

After working at two software companies in Austin, Texas, John began law school in 2005 at the University of Oregon School of Law in Eugene, Oregon. During law school, John served as an associate editor for the Oregon International Review of Law and as an on-campus research assistant for two professors at the Knight Law School. Knowing the areas of law he wished to specialize in after law school, John focused his legal studies on intellectual property, business law, and computer law.

Current areas of focus involve copyright and trademark law including the Digital Millennium Copyright Act (DMCA) in addition to cyber law matters including domain squatting issues, cease and desist letters, and disputes over virtual property. John has sent countless DMCA takedown notices and secured numerous federal subpoenas on behalf of his clients, and is efficient in removing infringing content hosted online.


Moreover, John provided intellectual property legal assistance during the development of a multi-million dollar software product released in 2010, including creation of the DMCA policy, assistance with the End-User License Agreement, and Privacy Policy. In 2011, John successfully defended several clients in Righthaven and other copyright litigation suits.

As a Colorado patent attorney, John also has experience addressing office actions and responses for software, nanotechnology, and mechanical patents on both the federal and international level. John has drafted the claims and specifications for several pending nanotechnology and mechanical patents. For corporate clients, John has drafted End-User License Agreements, provided international patent strategy advice, addressed trademark infringement claims, copyright assignment questions, non-disclosure agreements, licensing valuation, and more.

John Arsenault represents plaintiffs and defendants as an intellectual property attorney in any state or federal matters involving infringement or licensing issues. John's previous background in the software industry places him in a unique position to accurately and efficiently answer intellectual property and computer law questions for clients as both an expert in technology and as an IP attorney.

John serves clients throughout Colorado, including Denver, Englewood, Boulder, Broomfield, Longmont, Westminster, Louisville, Fort Collins, Colorado Springs, Golden, Greenwood Village, Highlands Ranch, Littleton, Vail, Aspen, Beaver Creek, Denver County, Adams County, Jefferson County, Boulder County, Arapahoe County, Douglas County and Weld County, and nationwide on federal patent, trademark, and copyright matters.
