District Court Erroneously Relied on Expert Testimony in Anticipation Determination

**DISTRICT COURT ERRONEOUSLY RELIED ON EXPERT TESTIMONY IN ANTICIPATION DETERMINATION

Bd. of Regents of the Univ. of Tex. Sys. v. Boston Sci. Corp., 24-2062, 24-2063 — Yesterday in an opinion by Judge TARANTO, the Federal Circuit reversed a district court judgment that BSC had infringed UT’s patent for a drug-releasing biodegradable polymer. BSC argued that a single prior-art reference anticipated three limitations claiming a “biodegradable polymer fiber” composed of a “second phase,” to mean “the discrete drug-containing regions dispersed throughout the fiber,” those phases “being immiscible.”

The Federal Circuit agreed. UT’s expert had distinguished the prior art as limited to “radial direction” drug release via chewing and to “contiguous” drug phases, unlike the patent’s tissue-engineering/stent applications and noncontiguous phase. The court found the prior art’s teachings were “plainly broader” than testified to: they did not require radial elution, were not limited to chewing gum, which was listed as just one of several embodiments, expressly allowed noncontiguous phases covered by UT’s patent, and disclosed that the “active agent” and “wall material . . . must be immiscible with each other.”
