Shumaker & Sieffert focuses on delivering legal services in the areas of Patent Prosecution, IP Strategy, Post-grant Proceedings, and IP Portfolio Engineering.  

Although the firm provides substantive patent law support, including patent law expert advice and testimony, in offensive and defensive patent infringement matters, our attorneys do not handle patent litigation per se.

Rather, the firm's patent attorneys are dedicated to building patent portfolios through patent application preparation and prosecution, counseling clients in reducing patent infringement risk through patent noninfringement and invalidity opinions and freedom-to-operate studies, initiating or defending post-grant proceedings such as Ex Parte Reexamination and Inter Partes Reviews, and building and evaluating patent portfolios.
