Software Patent Attorney

Forsgren Fisher McCalmont DeMarea Tysver, Minneapolis & Kansas City

Daniel A. Tysver

Dan Tysver has been helping to patent software inventions for over thirty years. During this time, Dan has obtained patents on a variety of computing inventions, including mobile apps, artificial intelligence, data analytics, data storage, business methods, networking, and file systems.

Dan’s award-winning BitLaw website has provided free information on software patents and patent law to the public for decades. Hundreds of thousands use the website every year to understand how the patent law applies to computer software and hardware inventions, and for information on the patent process.

Because of Dan’s focus on patenting digital inventions, he has a great deal of experience in dealing with subject-matter eligibility issues. These issues 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). He has also presented numerous legal seminars explaining the intricacies of this arcane area of the law, and how software is still largely protectable under Section 101 of the United States Patent Act.

Dan is the primary outside intellectual property counsel for companies ranging from the Fortune 100 to start-up companies and solo inventors.

Feel free to contact Dan if you have any questions or if you would like to discuss the patent process with him.
