The Federal Circuit has held that the voluntary dismissal of a district court complaint without prejudice does not prevent a lawsuit from triggering the statutory time bar for inter partes review (IPR). In an opinion issued on August 16 in Click-to-Call Technologies v. Ingenio, that central holding was reduced to a brief footnote that was decided 10-2 by the full Federal Circuit, while a three-judge panel ruled that the Patent Trial and Appeal Board’s (PTAB’s) contrary interpretation of the statute governing the time bar (35 USC Section 315(b)) was erroneous.
