The Death of the 'Should Have Known' Standard: In re Bose and Fraud on the PTO

The Federal Circuit reset the bar for fraud on the Trademark Office, holding that a registration falls only on clear and convincing proof of a subjective intent to deceive.

In In re Bose Corp., 580 F.3d 1240 (Fed. Cir. 2009), No. 2008-1448 (decided August 31, 2009), the U.S. Court of Appeals for the Federal Circuit dismantled the standard that had governed fraud claims before the Trademark Trial and Appeal Board for the previous six years. Writing for a panel of Chief Judge Michel, Judge Dyk, and Judge Moore, Chief Judge Michel reversed the Board’s cancellation of Bose’s WAVE registration and held that fraud on the U.S. Patent and Trademark Office requires a subjective, specific intent to deceive — proven by clear and convincing evidence — not the negligence-flavored “knew or should have known” test the Board had been applying. The decision did not merely correct an outcome; it reset the doctrine, sharply curtailing a wave of fraud counterclaims that had become a routine feature of opposition and cancellation practice.

At a glance

  • Case: In re Bose Corp., 580 F.3d 1240 (Fed. Cir. 2009), No. 2008-1448.
  • Decided: August 31, 2009; panel of Michel (author), Dyk, and Moore.
  • Mark at issue: WAVE, registered by Bose for a range of audio and video goods.
  • The statement: In a 2001 combined Section 8 and Section 9 renewal, Bose’s general counsel declared continued use of the WAVE mark on goods that included audio tape recorders and players — products Bose had stopped manufacturing and selling in the late 1990s.
  • The Board’s ruling: Applying Medinol v. Neuro Vasx, the TTAB found fraud because the declarant knew or should have known the statement was false, and cancelled the entire WAVE registration.
  • The holding: Fraud requires a knowing, material misrepresentation made with the intent to deceive the PTO; the evidence must be clear and convincing; negligence and even gross negligence are not enough.
  • Outcome: Reversed and remanded; the registration was to be restricted to reflect actual use rather than cancelled outright.

How Medinol turned fraud into a numbers game

To understand what Bose changed, you have to understand what it replaced. In Medinol Ltd. v. Neuro Vasx, Inc., 67 U.S.P.Q.2d 1205 (T.T.A.B. 2003), the Board had announced that a material misrepresentation made when the registrant “knew or should have known” of its falsity constituted fraud — regardless of the declarant’s actual state of mind. The phrasing collapsed the line between deceit and carelessness. Because trademark declarations routinely overstate the goods or services on which a mark is actually used, Medinol gave challengers a powerful and easily pleaded weapon: identify a single good in the registration on which the mark was not in use at the relevant date, and the entire registration was vulnerable to cancellation for fraud.

Fraud counterclaims proliferated accordingly. They became a near-reflexive addition to oppositions and cancellations, valuable less for their likelihood of success than for the in terrorem leverage they created — the threat that a paperwork imprecision could vaporize an entire registration. Bose arose squarely from that practice. Bose had opposed an application for HEXAWAVE, and the applicant counterclaimed that Bose’s WAVE renewal was fraudulent because Bose had certified continued use on audio tape recorders and players it no longer sold. The Board, applying Medinol, agreed and cancelled the registration in full.

”Should have known” is not “intended to deceive”

The Federal Circuit’s correction was rooted in first principles. Fraud, the court emphasized, is a species of deceit, and deceit requires a culpable mental state. Drawing on its own precedent and on general fraud doctrine, the panel held that “a trademark is obtained fraudulently under the Lanham Act only if the applicant or registrant knowingly makes a false, material representation with the intent to deceive the PTO.” The court was blunt about the gap between that standard and the one the Board had been using: by “equating ‘should have known’ of the falsity with a subjective intent,” the TTAB had “erroneously lowered the fraud standard to a simple negligence standard.”

The panel then drove the point home with a sentence that has been quoted in nearly every fraud decision since: “Subjective intent to deceive, however difficult it may be to prove, is an indispensable element in the analysis.” Negligence is not fraud. Even gross negligence does not by itself establish the requisite intent. And the burden of proof is demanding — clear and convincing evidence, the same elevated standard that governs fraud and inequitable conduct in patent cases. A challenger may not infer intent from the mere fact that a statement turned out to be false; deception must be the “single most reasonable inference” from the evidence.

Applied to Bose, the record could not carry that weight. Bose’s general counsel testified that he believed the continued shipment of repaired WAVE-marked goods back to customers constituted use in commerce sufficient to support the renewal. Whether or not that legal belief was correct, it was honestly held, and an honest misunderstanding — even a mistaken one — is the antithesis of an intent to deceive. As the court put it, there is no fraud “if a false misrepresentation is occasioned by an honest misunderstanding or inadvertence without a willful intent to deceive.”

The remedy: restriction, not cancellation

A subtle but consequential part of the decision concerns what happens when a registration contains goods on which the mark is not in use but fraud cannot be proven. The Board’s instinct had been all-or-nothing: fraud meant cancellation of the entire registration. The Federal Circuit decoupled the two. Bose’s WAVE registration was not fraudulently obtained, but it did overstate the goods. The proper response was not to destroy the registration but to restrict it — to delete the discontinued audio tape recorders and players so the registration reflected commercial reality. The court reversed the cancellation and remanded for that narrower correction.

That distinction matters enormously in practice. It means that an inaccurate identification of goods, standing alone, is a problem of scope, not of validity. The registrant who overstated loses the overstated goods; the registrant who lied loses everything. By separating the consequences, Bose made the fraud finding a genuinely exceptional outcome reserved for genuine deceit, while channeling ordinary inaccuracies into the far less drastic remedy of amendment.

Open questions

  • How is “intent to deceive” proven without a confession? Bose requires subjective intent but acknowledges it will rarely be admitted. The contours of what circumstantial evidence suffices — and whether “reckless disregard” can substitute for intent — were left for later cases to develop.
  • Does reckless disregard satisfy the standard? The court expressly declined to decide whether reckless disregard for the truth equates to intent to deceive, a question the Board and Federal Circuit have continued to wrestle with in the years since.
  • What counts as material? Bose reaffirmed materiality as an element but did not catalog which misstatements rise to the level that affects the PTO’s decision to register.
  • How far does the patent-law analogy run? By importing a clear-and-convincing standard reminiscent of inequitable conduct, the court invited comparison to a body of patent doctrine that has itself since tightened.

Implications

  • Fraud became hard to win again. After Bose, a challenger must prove a culpable mental state by clear and convincing evidence, sharply reducing the success rate of fraud counterclaims and their settlement leverage.
  • Overstated goods are a scope problem, not a death sentence. An inaccurate identification typically results in restriction of the registration, not cancellation, absent proof of deceit.
  • Plead intent, not just falsity. A bare allegation that a statement was false will not survive; pleadings must allege facts supporting a subjective intent to deceive.
  • Declaration practice still demands care. Bose lowers the fraud risk but not the accuracy obligation; the cleanest defense remains a declaration that is true when signed and signed by someone who understands what it asserts.
  • The standard now anchors the doctrine. Subsequent Board and Federal Circuit fraud decisions build directly on Bose’s intent-to-deceive framework, making it the foundational citation in this area.

Frequently asked questions

What did In re Bose actually change? It replaced the TTAB’s Medinol “knew or should have known” test — which functioned as a negligence standard — with a requirement of subjective, specific intent to deceive the PTO, proven by clear and convincing evidence.

Was Bose’s WAVE registration cancelled? No. The Federal Circuit reversed the cancellation. Because there was no fraud, the registration was to be restricted to delete the goods (audio tape recorders and players) on which the mark was no longer used, not cancelled in its entirety.

Is reckless disregard for the truth enough to prove fraud after Bose? Bose did not decide that question, expressly leaving it open. The relationship between reckless disregard and intent to deceive has remained a contested issue in TTAB practice in the years since.
