In an intellectual property lawsuit filed by Cepheid against Roche, a US district court has stayed a hearing on whether a PCR patent owned by Roche is invalid until the companies finish ongoing arbitration hearings.

Cepheid last week filed suit against Roche seeking to invalidate a pair of PCR patents owned by Roche.

Patent watchdog firm Troll Busters has chosen to abandon its lawsuit against more than a dozen life science companies for false patent marking related to various nucleic acid detection, amplification, and cloning technologies, according to recently filed court documents.

A US district court has dismissed a lawsuit filed earlier this year against more than a dozen life science companies alleging that they falsely marked certain nucleic acid detection, amplification, and cloning technologies as being patented after the relevant patents expired.

The patent reexamination is intended to challenge a larger "PCR patents duopoly" enjoyed by Roche and Life Technologies, according to an associate at the IP firm that initiated the patent reexamination last month.
