Enplas Infringed LED Lens Patents, Says US Court

Jury awards Seoul Semiconductor $4.07 million in damages

Seoul Semiconductor has announced that it has prevailed in a patent infringement lawsuit regarding LED backlight lens technology against Japanese lens maker Enplas.

In October 2013, Enplas sued Seoul in US federal court in California seeking a declaratory judgment that its products do not infringe Seoul's LED backlight lens patent and backlight system patent.

Enplas also asked the court to find that Seoul's patents are invalid. In April 2014, Seoul filed an answer, defending its patents and asserted counter-claims that Enplas is actively inducing infringement of Seoul's patents.

On March 24, 2016, a California federal jury rendered a verdict finding that Enplas actively induced infringement of Seoul's patented technology with respect to all of the asserted patent claims and that such infringement was willful. 

The jury unanimously agreed that Seoul's LED backlight lens patents are valid and rejected Enplas's invalidity arguments. The jury awarded Seoul $4.07 million in damages for inducement.



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.
