Should private sales of an invention be considered public disclosures when defending patent rights?
On September 14, 2026, the U.S. Court of Appeals for the Federal Circuit ruled that a private sale of an invention does not qualify as public disclosure. The decision vacated a $486,400 jury damages award and ordered a new trial for the patent case.
Why it matters
The ruling clarifies that private commercial transactions do not satisfy the public availability criteria required to trigger the patent grace period under the America Invents Act. This distinction helps define the boundary between confidential business dealings and public patent bars.
The court reversed two previous district court claim constructions and vacated a $486,400 jury award. The case centers on an invention sold to one customer in July 2012 prior to a 2013 patent application filing.
The players
U.S. Court of Appeals for the Federal Circuit
This specialized court has nationwide jurisdiction over appeals in patent cases.
NCS Multistage Inc.
This is the company involved in the patent dispute regarding the sale of its product.
Nine Energy Service, Inc.
This is the entity involved as the opposing party in the patent infringement litigation.
The details
The court determined the sale was private because the invention was delivered in sealed packaging accompanied by confidential technical documents. Because the technology was not sufficiently available to the public, the court found it did not constitute a public disclosure.
Timeline
July 2012: NCS sold its product to a single customer.
2013: NCS filed its patent application.
September 14, 2026: The Federal Circuit issued its decision in the NCS Multistage case.
Macro View
This decision refines the application of the America Invents Act by establishing that private sales do not trigger the patent grace period. It mirrors historical shifts in patent law where courts define strict boundaries for what constitutes public versus private information.
Businesses and innovators must now be more precise in how they classify initial product sales to ensure they do not accidentally forfeit potential patent rights. Legal uncertainty regarding existing awards may impact the valuation and patent strategy of companies in similar sectors.
The takeaway
Companies should maintain rigorous confidentiality protocols for all pre-patent sales to avoid future legal challenges. Proper documentation of sale terms is essential to proving that a transaction remains private rather than public.
