His practice spans a diverse range of technology areas, including software, electronics, communications, and medical devices. Specifically, he handles matters involving business intelligence, telecommunications, network, biometric, semiconductors, and physical access control technologies, including standard essential patents (SEPs).

Rozylowicz demonstrates a balanced practice, representing both petitioners and patent owners in patent challenges. His experience includes working on both the plaintiff and defendant sides in tracked cases. He is particularly notable for his extensive involvement in Patent Trial and Appeal Board (PTAB) proceedings, having managed over 90 AIA post-grant matters. He is a respected figure in the PTAB community, serving as a member of the board of directors and currently as Vice President of the PTAB Bar Association.

A prominent case in his portfolio is Apple Inc. v. Resonant Systems Inc. (IPR2024-00807), an inter partes review at the PTAB where he represented Apple Inc. as the petitioner. This proceeding involved patents related to haptic feedback devices, and resulted in claims 2 and 3 being invalidated. There was also a related district court action where the Federal Circuit denied Apple's mandamus petition to transfer the case out of the Western District of Texas.

He earned his J.D. from George Washington University Law School (2003), an M.S. in Electrical Engineering from George Mason University (1999), and a B.S. in Electrical Engineering from the United States Air Force Academy (1994).
