About Nathan Sportel

Nathan’s success in petitioning for IPR has consistently led to IPR institution and patent invalidity. Conversely, when defending a patent’s validity, Nathan has always successfully defended the patent at the institution phase, saving clients significant legal fees.

Nathan is a recognized authority in IPR proceedings, having penned several articles in the field and as a counsel in the precedential opinion Sotera v. Masimo, which created the “Sotera Stipulation” – a tool used by almost all post-grant practitioners to avoid the dreaded Fintiv discretionary denials. Indeed, Sotera stipulations, the mechanism created by Nathan and his team, was previously endorsed by the USPTO as way to avoid institution denial under Fintiv.

As a former patent examiner, Nathan understands how to prepare an IPR petition and find prior art that can lead to client success. Nathan can efficiently search for prior art, using the techniques taught by the USPTO to patent examiners, and put together a strong IPR petition. Nathan understands the compressed schedule of IPRs and excels at presenting cases efficiently.
