Delhi High Court voids Philips royalty claim against DVD makers
The Delhi High Court set aside a 2018 decree compelling two DVD player manufacturers to pay royalty to Philips for alleged infringement of its DVD decoding technology patent. The court determined that Philips failed to establish infringement and that the patent was not proven to be a Standard Essential Patent (SEP), additionally citing patent exhaustion as a defense.
Key Takeaways
- A Division Bench of Justice C. Hari Shankar and Justice Om Prakash Shukla allowed appeals by K.K. Bansal and Rajesh Bansal.
- Philips sued on Indian Patent IN-184753, which expired on February 12, 2015 during the case.
- The court said Philips produced no claim charts mapping the suit patent to DVD Forum standards, despite relying on SEP arguments.
- Philips' witness did not file logs or details of the alleged infringement tests on the DVD players.
- The court set aside punitive damages against Rajesh Bansal and cited international exhaustion tied to MediaTek-sourced PCBs.
Why It Matters
The immediate effect is that Philips loses the royalty decree and punitive damages award against the two DVD player makers. The ruling also raises the bar for SEP cases by demanding claim charts and evidence that links patent claims to the standard, not just certificates from outside firms. It matters beyond this dispute because the bench also relied on international exhaustion and MediaTek chip sourcing to bar enforcement. The next signal to watch is whether future Philips or SEP pleadings in India include claim charts and witness-backed infringement logs at filing.
