Nichia Wins Injunction Against Everlight

German court grants preliminary injunction on alleged YAG patent infringement

A request filed last month by Nichia for three preliminary injunctions against Everlight Electronics, has been granted by the Duesseldorf District Court in Germany. 

The injunctions alleged that the white LED products "˜334-15/X1C5-1QSA', "˜334-15/T2C2-1TVB' and "˜XI3535-KT577J1-03201-000P' manufactured by Everlight and distributed in Germany infringe Nichia's YAG patent EP 936 682 (DE 697 02 929). The patent involves combining YAG-based phosphor with GaN-based blue LED.

The Duesseldorf District Court admitted Nichia's arguments that the Everlight LEDs infringe claim 1 of Nichia's YAG patent and granted the preliminary injunctions on October 24, 2016 and November 7, 2016, respectively (File Nos. 4a O 104/16, 4a O 112/16 and 4a O 113/16). 

Due to the particular urgency, the preliminary injunctions were granted ex parte, i.e. without prior hearing of Everlight. On November 10, 2016, the preliminary injunctions were served on Everlight. These are preliminary measures which can still be remedied by Everlight, according to Nichia.



AngelTech Live III: Join us on 12 April 2021!

AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.

2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.

We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.

We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.

Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.

Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.

So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
