Daniel L. Bruzzone

Partner – Patent Attorney

Daniel Bruzzone is a partner at Patterson Thuente IP. His practice consists of patent drafting and prosecution, patent portfolio management, performing patentability and clearance searches, and preparing patent invalidity opinions, as well as patent and trademark litigation support.

Prior to becoming a patent attorney, Daniel spent six years in research and development at a Fortune 100 company, developing products used in photovoltaic modules. He worked on the development of commercialized polymers used in adhesives (polyisobutylene- and acrylic block copolymer-based PSAs) and solar encapsulants. These efforts required expertise in rheological tests such as DSC, DMA, TSA, TSC, peel, shear, and tack, among others. Daniel also performed optical characterization, including spectrophotometry, haze testing and color testing, on materials such as flat-panel Fresnel lenses and solar glass/encapsulant constructions.

Daniel has been honored as a North Star Lawyer for providing 50+ hours of pro bono legal assistance since 2016, a coach for the Giles S. Rich IP Moot Court team at Mitchell Hamline School of Law since 2014, and has been an election judge in every Minnesota election since 2009. Outside of work, you might find Daniel at the woodworking shop or volunteering behind the desk of the local tool library.
