Yesterday Judge Williams issued an oral order in Board of Regents, The University of Texas System v. Boston Scientific Corporation, C.A. No. 18-392-GBW (D.

But it turns out that that second part—showing publication—is kind of important.

In F'real Foods LLC v. Hamilton Beach Brands, Inc., C.A. No. 16-41-CFC, Judge Connolly excluded a Japanese Patent Office Utility Model Publication on a motion in limine because the defendants failed to show that it was publicly accessible under § 102, based largely on defendants' own position in opposing IPR estoppel.

Couldn't Have Found Reference = No IPR Estoppel

The F'real defendants had previously filed an unsuccessful IPR, and plaintiff moved to exclude the reference based on IPR estoppel. …
