Background
Artec Europe, a Luxembourg-based maker of professional 3D scanners, sued Chinese electronics company Shenzhen Creality 3D Technology and its subsidiary Shenzhen Jimuyida Technology in 2022, alleging that Creality’s consumer-grade 3D scanners (including the CR-Scan series) infringed three Artec patents. The asserted patents—U.S. Patent Nos. 7,768,656 (the ‘656 Patent), 8,488,129 (the ‘129 Patent), and 10,962,357 (the ‘357 Patent)—cover methods and systems for three-dimensional scanning using structured light projection and multi-frame image processing.
The case proceeded through claim construction in a Markman hearing held in two sessions (June and July 2024), where Judge Merchant construed disputed terms in the patent claims. Following discovery, both sides filed dispositive motions: Creality moved for summary judgment of non-infringement and invalidity, and Artec filed a Daubert motion to exclude portions of testimony from Creality’s technical expert, Dr. Steven Gortler.
The Court’s Holding
In a 35-page Memorandum and Order, Judge Merchant granted in part and denied in part both motions. On summary judgment, the court found that some infringement and validity issues presented genuine disputes of material fact that must go to a jury, while others could be resolved as a matter of law. The mixed ruling narrows the claims and defenses that will be tried but preserves a substantial portion of the case for trial.
On the Daubert motion, the court partially excluded Dr. Gortler’s expert testimony, finding some opinions lacked sufficient reliability or ventured beyond his expertise, while allowing other portions of his testimony to stand. The partial exclusion strengthens Artec’s position on certain technical issues heading into trial.
The court ordered the parties to file a joint letter by April 27, 2026, addressing estimated trial duration, signaling that trial is imminent.
Key Takeaways
- The case illustrates the increasing enforcement of patent rights in the consumer 3D scanning market, as established players seek to protect their technology against lower-cost competitors from China.
- The partial Daubert exclusion highlights the importance of expert qualification and methodology in patent cases—technical experts must stay within their demonstrated competence and apply reliable methods.
- With trial approaching, this case could set important precedents for structured-light 3D scanning patents, a technology with applications spanning manufacturing, healthcare, and entertainment.
- For Chinese technology exporters, the case underscores the litigation risks of selling patent-protected technology products in the U.S. market.
Why It Matters
The 3D scanning market is growing rapidly, driven by demand in manufacturing quality control, medical imaging, augmented reality, and digital archiving. This case pits a European pioneer in professional 3D scanning against one of the largest Chinese consumer electronics companies, and the trial outcome could significantly affect the competitive landscape for affordable 3D scanners sold in the United States. The mixed summary judgment ruling ensures that both infringement and invalidity will be litigated at trial, making this one of the most comprehensive 3D scanning patent trials to date.
