Viken Detection Corporation filed Viken Detection Corporation v. Videray Technologies Inc., No. 1:26-cv-14192-PBS (D. Mass.), on September 11, 2026, before Judge Patti B. Saris. The complaint is a single-count patent-infringement suit on U.S. Patent 12,718,966, titled "X-Ray Chopper Wheel Assembly and Method," issued August 25, 2026 to inventor Peter J. Rothschild. Viken demands a jury trial.
Patents and accused products
The complaint asserts U.S. Patent 12,718,966. Asserted claims: at least Claim 29. Viken identifies the accused products as Videray's handheld scanners called the PX1, PX Lite, and PX Ultra. The complaint says Viken examined a PX1 and alleges the PX Lite and PX Ultra share the same accused features.
The '966 patent is a continuation in a family that includes U.S. Patents 10,770,195, 11,200,998, and 11,776,706. Viken says it already asserted those three patents against Videray as plaintiff-in-counterclaim in Civil Action No. 23-cv-13035 (D. Mass.) (the Existing Action), where discovery is complete, and that it filed this separate case because the '966 patent had not yet issued when those counterclaims were filed.
What the patents cover
U.S. Patent 12,718,966 (X-Ray Chopper Wheel Assembly and Method) covers an X-ray chopper-wheel assembly with a disk chopper wheel and a smaller source-side scatter plate that absorbs X-rays, held nearly parallel to the wheel across a gap meant to limit leakage. An optional output-side scatter plate can cut leakage further, aiming for safer, lighter disk-chopper systems, including handheld scanners.
Asserted claims: at least Claim 29. Claim 29 covers an X-ray chopper-wheel assembly with (1) a chopper wheel that has at least one opening to pass X-rays from a source side to an output side, has a solid cross-sectional area in its rotation plane, and is configured to absorb X-rays from the source, and (2) a plate whose solid cross-sectional area in a parallel plane is substantially smaller than the wheel's, arranged so that scattered X-ray radiation from the wheel is limited to no more than 10% of scattered radiation. The claim pairs a spinning chopper wheel with a smaller nearby plate used to control scatter.
What the lawsuit is about
Viken alleges direct and induced infringement of at least Claim 29 by making, using, selling, offering to sell, or importing the Accused Products. It also alleges willful infringement based on Videray's notice of the related family patents, the Existing Action, and founder Paul Bradshaw's prior work at Viken. Viken seeks a preliminary and permanent injunction, damages (including lost profits and a reasonable royalty), enhanced damages up to treble, attorney fees under 35 U.S.C. § 285, costs, and interest. The complaint notes that alleged prior art from the Existing Action, including the Mini-Z, was before the examiner who allowed the '966 patent.
What it means
This is a competitor fight in Massachusetts federal court over handheld backscatter X-ray scanner hardware. Viken already has a related family-patent case against Videray underway and is adding a newly issued continuation patent aimed at the same product line.
What to watch next
Watch for Videray's answer or early motions in No. 1:26-cv-14192. Watch whether the parties seek to coordinate or consolidate this case with the Existing Action, No. 23-cv-13035. Also watch how Claim 29's scatter-limit and plate-size limitations are framed in any claim-construction or preliminary-injunction practice.
