The Application File Never Really Closes: Implications of Recent Case Law on the Prosecution Record

Patent prosecution is often treated as a sequence of discrete tasks: respond to the office action. Amend the claim. Make the argument. Obtain allowance. Move on. Recent U.S. Court of Appeals for the Federal Circuit decisions show why that model is incomplete. The prosecution record can later shape infringement theories, affect whether a reference qualifies as prior art, and determine whether a statutory avenue for review remains available. The cases arise under different doctrines, but they support one durable conclusion: prosecution is part of the patent’s long-term risk allocation.

Amici Tell Justices to Rein In USPTO’s ‘Settled Expectations’ Doctrine

Following a July petition for writ of certiorari filed by Kahoot AS! asking the U.S. Supreme Court to consider whether the U.S. Patent and Trademark Office’s (USPTO’s) “settled expectations” doctrine for denying inter partes review (IPR) requests is authorized under the patent statute, the PTAB Bar Association and other amici this past week have urged the Court to take up…

New Bill Would Overhaul Judicial Misconduct Proceedings in Light of Moore-Newman Battle

Representative Scott Fitzgerald (R-WI) has introduced a bill to amend the Judicial Conduct and Disability Act, inspired by U.S. Court of Appeals for the Federal Circuit (CAFC) Judge Pauline Newman’s fight to restore her status as an active judge, following a three-year suspension of her duties initiated by CAFC Chief Judge Kimberly Moore.

Schedule A Litigation Is Not the Problem: Online Counterfeiting Is

Online counterfeiting has become ubiquitous. A seller located anywhere in the world can create a digital storefront, copy a brand owner’s photographs and product descriptions, adopt a business name that reveals nothing, and begin selling into the United States before the brand owner even knows the account exists. If the seller is discovered and enforcement begins, the listing disappears, the money moves out of the country and beyond the practical reach of the court system, and a new account surfaces under a different name. Then the entire process repeats.

Federal Circuit Vacates PTAB Rejection of Catheter Patent Application Over Incorrect Claim Construction

The U.S. Court of Appeals for the Federal Circuit (CAFC) issued a decision today in In re Incept LLC, vacating and remanding a Patent Trial and Appeal Board (PTAB) decision that had affirmed an examiner’s rejection of a medical catheter patent application as obvious. Since the Board’s obviousness analysis relied on an incorrect construction of the claim term “flow barrier,” the CAFC declined to reach the underlying obviousness question and returned the case to the Board for further proceedings.
