Philcor also did not dispute the validity of Seoul Semiconductor’s patents and agreed to pay past damages and a license fee.

Seoul says that the damages and licensing fee affirm that Philcor is committed to respecting Seoul’s intellectual property of patents in its technologies for high-voltage operation (Acrich Driver), Acrich MJT (multi-junction technology over-6V high power chip), filament LED bulb structure, LED chip fabrication, LED packaging, and LED epitaxial growth.
