Sentencing and Charges
U.S. District Judge G. Murray Snow sentenced Israeli citizen Guy Galanti, a 48-year-old senior manager at Green Technology Investments (GTI) in Scottsdale, Arizona, to time already served and three years of supervised release. The sentence, issued on June 22, 2026, follows Galanti’s May 2026 guilty plea to conspiring to steal GTI’s trade secret, the Glass Detect Design, a system for detecting microscopic defects in glass semiconductor wafers.
GTI’s Glass Detect Design
GTI, a Scottsdale-based firm that services and refurbishes semiconductor testing equipment, created the Glass Detect Design between January and August 2025. The design enables a testing machine to locate defects on glass wafers, a capability distinct from conventional silicon-based inspection and a competitive advantage in high-precision semiconductor manufacturing.
Principal Actors
Guy Galanti, the Israeli senior manager at GTI, is the only individual publicly identified. The co-conspirator, described as operating a Taiwanese company that directly competes with GTI, remains unnamed. U.S. District Judge G. Murray Snow presided over the case, while the U.S. Justice Department and the U.S. Attorney’s Office for the District of Arizona led the prosecution.
Timeline of the Case
- January–August 2025: Galanti transmitted photos, software, and technical data on the Glass Detect Design to the co-conspirator.
- September 10, 2025: He was charged with conspiring to steal a trade secret.
- September 11, 2025: He was arrested.
- May 26, 2026: He entered a guilty plea.
- June 22, 2026: The court imposed the sentence.
Case Metrics
Supervised release: three years.
Time served: roughly nine months in federal custody from September 2025 to sentencing.
Conspiracy period: eight months (January–August 2025).
Official Responses
The U.S. Justice Department confirmed the sentence and stressed the seriousness of trade-secret theft in high-technology fields. The U.S. Attorney’s Office noted that Galanti’s plea concluded a federal probe into cross-border intellectual-property espionage. Judge Snow’s remarks emphasized deterrence of future illicit acquisition of proprietary semiconductor technology.
Gaps in Public Information
Court filings do not reveal the co-conspirator’s name or the Taiwanese company’s identity, limiting insight into the foreign party’s role. The financial impact of the alleged theft was not quantified in the available documents.
