ETI Solid State Lighting is seeking to add a patent misuse defense against Signify, arguing that confidential licensing agreements disclosed during discovery revealed evidence that was unavailable before the lawsuit. I think it was 90,000 pages. 

The IES and NLB signed a memorandum of understanding to collaborate on lighting education, public outreach, and industry initiatives aimed at improving lighting quality, sustainability, and the built environment. Congratulations to both organizations. 

Leviton has named John Pannunzio General Manager of Viscor, effective 1 July, as longtime COO Santino Nemi retires after 37 years. Nemi will remain in an OEM agent role to support a smooth leadership transition. 

Elemental LED has rebranded its parent company as Elemental Brands, reflecting its expanding portfolio and U.S. manufacturing growth. Existing brands and customer relationships remain unchanged as the company positions itself for future expansion.
