Stephen F. Schlitz

Stephen F. Schlitz's patent litigation practice focuses on representing plaintiffs, particularly patent assertion entities (PAEs), in disputes involving sophisticated technologies. His tracked appearances show a clear emphasis on the plaintiff side, with two recorded plaintiff-side cases and no defendant-side matters. He has appeared as lead counsel in at least one significant case.

His experience spans key technological areas, including semiconductor devices and cellular communications. In Greenthread, LLC v. ON Semiconductor Corporation et al., where Schlitz was lead counsel for the plaintiff at The Stafford Davis Firm, PC, the case involved patents covering semiconductor devices with graded dopant regions. This case was administratively closed pending inter partes review (IPR) proceedings before the Patent Trial and Appeal Board (PTAB), indicating his involvement in matters that navigate both district court litigation and post-grant review challenges. For INVT SPE LLC v. T-Mobile USA, Inc., where he appeared for Buether Joe & Counselors, LLC, the underlying subject matter involved patents related to LTE and 3G cellular communication standards, as highlighted in related Federal Circuit appeals for INVT SPE LLC.
