Key point(s):

In re Black, No. 2018-1166 (July 8, 2019) (nonprecedential); Patent App. No. 13/542,146

Key point(s):

  • The hallmark of whether the PTAB has made a new ground for rejection is whether applicants have had an opportunity to respond to the “thrust of the rejection.”


General Electric Company v. United Technologies Corporation, No. 2017-2497 (July 10, 2019) (precedential) (3-0); Patent No. 8,511,605

Key point(s):

Quake v. Lo, 2018-1779, 2018-1780, 2018-1782 (July 10, 2019) (precedential) (3-0); Patent No. 8,008,018 and Patent App. No. 12/393,833

Key point(s):

  • On remand, the PTAB need not reopen the record if (1) the proffered testimony is not inconsistent with the same witness’s previous testimony; (2) there is a reviewable transcript of discussion of the issue with the parties; and (3) the PTAB provides written, reviewable reasoning for why it did not allow the new evidence into the record.


TQ Delta, LLC v. Dish Network LLC, No. 2018-1799 (July 10, 2019) (precedential) (3-0); Patent No. 8,611,404

Key point(s):

  • A change in claim construction by the PTAB during an IPR is not an APA violation if the parties have adequate notice of the change.
  • Construction of a claim limitation for an IPR Final Written Decision is not a change in claim construction if the PTAB did not previously construe the limitation.
  • The PTAB’s decision to uphold patent claims does not invoke the “competitor standing” doctrine, if the competitive landscape (e.g., prices and competitors) for the field remains unchanged.
  • The AIA estoppel provision does not create injury in fact for standing when the party does not practice the patent claim and injury is speculative.


Cisco Systems, Inc. v. TQ Delta, LLC, No. 2018-1806, , No. 2018-1917 (July 10, 2019) (precedential) (3-0); Patent No. 8,611,404

Key point(s):

  • Minor distinctions in spelling and pronunciation are not enough to overcome similarity in overall commercial impression of marks.
  • Registrations do not demonstrate that consumers actually are conditioned to distinguishing among marks; one needs evidence of use of the marks.
