Here are a few highlights:
For low power receivers (consumer products like a phone or battery capable of receiving no more than 5 Watts from a wireless power transmitter), sold before 31 December 2014, WPC members are not charging royalties for patents that are essential for implementing low power receivers. This royalty-free policy for low power receivers will continue indefinitely provide more than 50 million low power receivers were sold before 31 December 2014. On 31 March 2015, IHS reported that 55 million units were shipped during 2014. That press release does not distinguish between Qi-compatible receivers and other wireless power receivers. This ambiguity was resolved in a presentation on 10 June 2015, during a meeting of the WPC’s Automotive Application Group, when David Green (Research Manager, IHS) said that the number of Qi compatible receivers shipped to date exceeded 50 M units on 31 December 2014. Note that this report does not necessarily settled the question whether or not the royalty-free policy will continue. Other contradictory reports may appear and companies can challenge the validity of the findings. The WPC is not in the position to decide if a market research report is correct.
WPC members also have agreed to license their patents on reasonable and non-discriminatory terms and conditions. Although none of the member companies have announced detailed license terms yet, the members agree that RAND terms and conditions will be determined such that they promote adoption of the Qi standard and rapid growth of the market.
Qi transmitter products described as a “fully compliant subsystem” are designed for integration into broader products, such as furniture and vehicles. Under certain conditions, manufactures may include the Qi logo on these systems without signing the Qi logo trademark license agreement.
