PTAB Was Wrong to Ignore an Applicant’s Prosecution Disclaimer Because of Examiner’s Reasons for Allowance

Federal Circuit Again Reminds PTAB that BRI Must Be Reasonable

Last fall, the Federal Circuit reversed a PTAB decision that affirmed an Examiner’s rejection of various claims in an ex parte reexamination because the Examiner’s interpretation of the claims, which the PTAB upheld, was unreasonably broad. In re Smith International, Inc., Appeal No. 2016-2303 (Fed. Cir. Sept. 26, 2017). The court’s decision is noteworthy because … Continue Reading

Error in Claim Construction Leads to Reversal of IPR Decision and Cancelation of Claims

Two recent Federal Circuit decisions illustrate how an error in construing claims may lead the court to reverse a PTAB final written decision. In Organik Kimya AS v.

Apple Inc., Appeal 2016-1599 (Fed. Cir. May 11, 2017). In … Continue Reading

Failing to Articulate Desired Claim Construction Before PTAB May Lead to Waiver

In the latest development in the ongoing patent battle between Google and SimpleAir Inc., a Federal Circuit panel agreed with SimpleAir that Google waived a claim construction it asserted on appeal because Google had failed to argue that construction before the PTAB.

Pending Bill Would Deliver More Judicial Scrutiny to USPTO and FDA Rules

 The House of Representatives recently sent to the Senate its bill (H.R.5) that combines six previous regulatory reform bills, including, as Title II of the bill, the “Separation of Powers Restoration Act.”  Section 202 of the bill effectively removes the option for courts to apply Chevron deference to agency rulemaking and interpretations.  Thus, rather than deciding … Continue Reading

PTAB Declines to Institute IPR on Immersion’s Indefinite Means Plus Function Claims

Petitioners are finding themselves caught in a Catch-22.  The PTAB declares claims too indefinite under Section 112 to construe, but then declines to address the patentabilty of the claims.  Section 112 deficiencies are not grounds to challenge a patent in an IPR, but the PTAB has authority to find such deficiencies. Recently, the PTAB decided … Continue Reading

Cir. 2016)), serve as a reminder that the broadest reasonable interpretation (BRI) standard does not permit an unreasonably broad construction. In addition, the PTAB’s related order (see Paper … Continue Reading
