The Daily Journal notes “In recent years, Daniel Yannuzzi’s practice has largely been ‘challenging and killing patents.’” Yannuzzi commented, “My role tends to be … litigating and defending against those challenges and effectively invalidating the patents where I can, which has been pretty frequent lately.”
One venue in particular in which he does that is the Patent Trial and Appeal Board in inter partes review. “Of all the IPRs that I’ve filed, I’ve never had one that has failed to be instituted,” Yannuzzi said.
Yannuzzi was also noted for successfully blocking patent assertions against his clients in federal court and for defending Snap, Inc. in two cases asserting patents against Snapchat technology related to image filters and lenses.
