Software Patent Attorney

Dan Tysver has been helping his clients obtain patents on software inventions for almost thirty years. Dan developed his reputation by providing patent counseling services primarily on computing technology, including general software applications, mobile apps, artificial intelligence, data storage, business methods, networking, and file systems. By authoring the BitLaw website, Dan has provided to the general public a great deal of information on software patents and patent law in general. Please look through the site for information on how the patent law applies to computer software and hardware inventions, and for information on the patent application process.

Because of his focus on patenting computing inventions, Dan has a great deal of experience in dealing with Section 101 / eligible-subject-matter issues that are frequently encountered when applying for or enforcing a patent on software technologies. He has written extensively on this topic on the Bitlaw website (see the Section 101 Index for a brief overview and links to deeper dives), and has presented numerous seminars to other patent attorneys on this topic.

After starting with a large firm in Minneapolis, Dan started the firm of Tysver Beck Evans to focus solely on intellectual property matters for his clients. For over twenty years, this firm specialized in protecting computer software, mobile device apps, medical devices, consumer electronics, and mechanical inventions. In January of 2021, the firm joined with some fabulous  litigation attorneys to form Forsgren Fisher McCalmont DeMarea Tysver, with offices in in Minneapolis, Minnesota and Kansas City, Missouri. Together, our new firm includes not only the expertise to create strong patent rights on your software inventions, but also the experience necessary to enforce those rights in front of a jury, before the Patent Trial and Appeal Board, and before the Federal Circuit.

Dan is the primary outside intellectual property counsel for companies ranging from the Fortune 100 to start-up companies and solo inventors. Information about Dan and the Forsgren Fisher McCalmont DeMarea Tysver law firm can be found at the firm’s home page and on Dan’s full bio page.  In addition, please feel free to contact Dan at or at 612-474-3330 if you have any questions or if you would like to discuss the patent process with him.

Dan received his undergraduate degree in physics from Carleton College and his law degree from Harvard Law School. He has been named a Super Lawyer and has previously been honored as a Top 40 IP Attorney by Minnesota Law and Politics. Dan has received an AV Preeminent Rating from Martindale Hubbell (described here).

Dan served for ten years as an adjunct professor of Software and Technology Law at the University of St. Thomas Graduate Programs in Software, and previously served as the adjunct professor of patent law at the University of Minnesota Law School. Dan is active in the legal community, having served on the governing council for the Computer/Tech Law Section of the Minnesota State Bar Association for more than twenty years.
