Patent Defenses Addressed On The Merits Even After Non-Infringement Finding Affirmed

Client Alert | 1 min read | 05.22.06

In Old Town Canoe Co. v. Confluence Holdings Corp . (May 9, 2006; Nos. 05-1123, 05-1148), a Federal Circuit panel affirms findings of non-infringement and no inequitable conduct based on motions for judgment as a matter of law ("JMOL"), but vacates JMOL findings of no invalidity and remands for further proceedings.  The patent-in-suit claims a method for making a laminated plastic boat hull by rotational molding, and the parties disputed whether, in the accused process, "coalescence" was "completed."  In finding non-infringement, the Federal Circuit affirms the district court's claim construction and agrees that the disputed limitation requires the plastic laminate to reach the end of coalescence, that is, its optimum state as disclosed in one of the patent diagrams.  Because the accused process is "brought to a halt," it does not infringe.

With respect to invalidity, the Federal Circuit concludes that the accused infringer presented enough evidence that a reasonable juror could decide against the patentee on each of the obviousness, enablement, and best mode defenses, and thus vacates the JMOL.  In contrast, patentee did not provide enough evidence for the Federal Circuit to conclude that the district court abused its discretion in finding no inequitable conduct, and thus JMOL of no inequitable conduct is affirmed.

While agreeing with the JMOL of non-infringement, Judge Mayer dissents from the panel's resolution of the invalidity and unenforceability counterclaims as lacking an actual controversy.

BIS Issues “Affiliates Rule” to Dramatically Expand Applicability of Entity and Military End-User Lists

On September 29, 2025, the U.S. Department of Commerce Bureau of Industry and Security (BIS) announced a sweeping Interim Final Rule (IFR), (the “Affiliates Rule”) expanding which entities qualify as Entity List or Military End-User entities, thereby subjecting those entities to elevated export control restrictions under the Export Administration Regulations (EAR). U.S. export restrictions applicable to entities on the Entity List, Military End-User (MEU) List, and Specially Designated Nationals and Blocked Persons (SDN List) now apply to foreign affiliates that are, in the aggregate, owned 50% or more by one or more of the aforementioned entities. An entity that becomes subject to these restrictions because of its ownership structure will be subject to the most restrictive controls that attach to any of its parent entities, regardless of ownership stakes....
