Timothy Grathwol Email & Phone Number

I'm Tim Grathwol, a registered patent attorney and Principal at Schwegman Lundberg & Woessner. I was also an adjunct professor at Mitchell Hamline School of Law for 13 years, where I taught a semester long third year course on patent application preparation and prosecution before the U.S. Patent and Trademark Office. Teaching is a passion of mine and the Patent Prosecution class and the many students who enrolled in my class at Mitchell was a highlight of my career.My practice includes U.S. and international patent procurement in mechanical, aerospace, and computer technologies, as well as infringement and validity counseling, freedom-to-operate studies, due diligence, and portfolio management. I have a wide range of technological experience including air handling, heating and cooling systems, aircraft and industrial power gas turbine engines, implantable medical devices, and a variety of software, computing and networking technologies.I have been involved in IP due diligence to support mergers and asset acquisitions for a variety of companies and technologies, including residential and commercial electronic security, air handling, heating and cooling systems, medical devices, home automation, and personal emergency response systems (PERS). I have extensive experience with various IP issues for medical devices, including cardiac and neuro stimulation, drug infusion, and vascular assist devices, prosthetic valves, and fixation for endovascular grafts and stent grafts. And I have represented several start-up medical device companies through patent portfolio development and procurement and counseled the clients through an IP due diligence to support sale of the company to a major medical device company.I have been fortunate enough to counsel clients in various other areas of IP management, including consolidating outside IP representation with a limited number of outside firms and building a comprehensive in-house IP management strategy. Such efforts have included managing large file transfers consolidating representation, reviewing and mitigating latent risks in the transferred portfolios, and building processes to manage and execute ongoing patent procurement, international filing strategies, and integration of IP procurement and infringement risk review into product development processes.
