NUBURU Receives Patents for Blue Laser Welding and Multi-kilowatt Blue Lasers

NUBURU, Inc. (“NUBURU” or the “Company”) (NYSE American: BURU), a leading innovator in high-power and high-brightness industrial blue laser technology, today announced that it has received additional patents that expand its intellectual property portfolio, broadly covering blue lasers for use in welding and other applications.

“These new patents expand our broad patent estate around blue lasers, particularly for welding copper and other metals,” said Dr. Mark Zediker, CEO and Co-Founder of NUBURU. “These patents also cover technologies like multi-kilowatt class blue lasers that have significant advantages compared to infrared lasers available from industry incumbents.”

NUBURU believes that its intellectual property provides strong protection to NUBURU’s blue laser technology and processes. Despite the significant advantages and efficiencies of blue lasers, major incumbents IPG Photonics (NYSE: IPGP), Coherent (NYSE: COHR), Lumentum (NASDAQ: LITE), and nLIGHT (NASDAQ: LASR) have not released an industrial blue laser, relying on infrared technology instead.

On March 28, 2023, the U.S. Patent and Trademark Office (USPTO) granted NUBURU’s patent for “Methods and systems for welding copper and other metals using blue lasers” (US Patent 11,612,957). This patent describes NUBURU’s blue laser technology and processes for welding multiple metal types and alloys including copper, aluminum, and stainless steel. The Company believes this patent provides technology and processes for more efficiently manufacturing batteries for electric vehicles, cell phones, and other electronic devices.

On April 14, 2023, the European Patent Office (EPO) granted NUBURU’s patent for “Multi KW Class Blue Laser System” (European Patent EP 3704772). As explained in the patent, “embodiments of the present inventions relate to a multi-kW-class blue fiber-coupled laser systems used for materials processing and laser welding applications, and in particular wavelengths in the wavelength range of about 400 nm to about 495 nm.” This unique beam combination methodology results in a laser source that is ideal for 3D printing applications as well as welding copper and other materials for building electric vehicles, cell phones, and other electronic products.

As of March 31, 2023, NUBURU has 190+ granted and pending patent applications throughout the world. The granted patents and pending applications cover all aspects of NUBURU’s technology and processes. NUBURU continues to prosecute the pending applications through to granted patents across multiple geographies to further protect NUBURU’s innovative and novel technology and processes for use in what NUBURU estimates to be a multi-billion-dollar serviceable addressable market (SAM).¹

About NUBURU

Founded in 2015, NUBURU, Inc. (NYSE American: BURU) is a developer and manufacturer of industrial blue lasers that leverage fundamental physics and their high-brightness, high-power design to produce faster, higher quality welds and parts than current lasers can provide in laser welding and additive manufacturing of copper, gold, aluminum and other industrially important metals. NUBURU’s industrial blue lasers produce minimal to defect-free welds that are up to eight times faster than the traditional approaches — all with the flexibility inherent to laser processing.
