Some important information:
The joint CD Player Patent License Agreement comprises the essential patents of Philips and Sony. A worldwide list of the essential patents, together with applicable expiry dates, is attached to the agreement. Under the terms of the standard license agreement we only require payment of royalties of patents where any of these are actually used – in other words, either in the country of manufacture or in the country of sale.
CD player licensees licensees have at all times the option to transfer to the latest version of the CD Player Patent License Agreement. In the event of such transfer, Philips shall not require payment of the entrance fee under the new license agreement.
As the CD Player Patent License Agreement comprises the CD-ROM and the CD-Text patents, the license provides for options so that licensees are licensed and only pay royalties in relation to the specific format(s) selected.
This agreement provides for the situation that, although the CD players manufactured are not covered by any essential patent in the country of manufacture, such CD players can be imported by the licensee or any third party into other countries where one or more of said essential patents subsist. This is especially relevant for manufacturers based in countries where the essential patents have expired.
