Delhi High Court Rules in Favor of Philips in DVD Patent Infringement Case

The Delhi High Court ruled in favor of Philips in its patent infringement case against Pearl Engineering, Powercube Infotech, and Siddharth Optical Disc.

Philips sued the companies in 2012, alleging unauthorized use of its Eight-to-Fourteen Modulation Plus (EFM+) coding, a Standard Essential Patent (SEP) for DVD production.

The defendants denied infringement, claiming they used a mechanical process and outsourced encoding. They also challenged the patent’s validity and accused Philips of delaying legal action, despite knowing about their activities since 2005-2007.

The court upheld Philips' patent, ruled that the defendants knowingly infringed it, and held them liable for aggravated damages. However, no injunction was granted as the patent expired in 2015.
