South Korean laser equipment maker Laserssel has transferred full ownership of six Korean patents related to probe pin inspection and bonding technologies to an individual named Hyung-Tae Kim in June 2025, according to Korean patent transfer records.
The patents assigned include:
KR1748582 – "Straight Degree Inspection Apparatus and Method for Probe Pin"
KR1818915 – "Probe Pin Height Measuring Device and Method"
KR1830072 – "Array Unit for Probe Pin Bonding Device"
KR1830073 – "Porous Vacuum Chuck of Probe Pin Bonding Device"
KR1830074 – "Pick Up Unit for Probe Pin Bonding Device"
KR1839366 – "Bonding Unit of Probe Pin Bonding Device"
All six patents relate to mechanical units used in probe pin bonding and inspection equipment, essential for semiconductor testing and packaging processes. The assignment record indicates a complete transfer of ownership rights from Laserssel to Kim.
Laserssel specializes in area-laser ("surface light source") technology, developing and manufacturing bonding systems for semiconductor, display, and battery packaging processes. The company's proprietary "area-laser" technology enables uniform beam intensity across a wide irradiation surface, allowing chips and PCBs to be bonded with high precision and consistency.
According to the company's 2024 financial filings, Laserssel reported ₩4.02 billion (approximately US$2.9 million) in revenue, an operating loss of ₩9.21 billion, and a net loss of ₩8.50 billion.
