Patents & Trademark Licenses

The Qi logo and Qi name are registered trademarks

The symboland the name "Qi" are registered trademarks in many jurisdictions. Use of these trademarks requires a license. Members of the Wireless Power Consortium can license the Qi symbol for use on their products. The trademark license is granted only for products that are visible in the Qi Certified Product Database. A products is not licensed to have the Qi logo if you cannot find a product in this database.

Using the Qi logo

Before using the Qi logo on your products, packaging or marketing materials, you must first obtain a trademark license. Terms and conditions for the Qi trademark license are included in the Qi logo license agreement, which is available for download here.

Understanding Qi patent licenses

Because some products that use our wireless power specifications may infringe patents owned by members and non-members, patent licenses may be needed on your Qi-compliant products. View our Consortium Charter for full details.

Here are a few highlights:

Low power receivers are royalty free

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.

Essential patents for other products must be licensed on RAND terms

WPC members have agreed to license their patents on reasonable and non-discriminatory (RAND) terms and conditions because RAND terms and conditions promote adoption of the Qi standard and growth of the market while providing an acceptable return on investment for all parties (see page 3 of the Consortium Charter).

The following companies have publicly announced royalty rates and lists of patents they claim are infringed by products that implement the Qi standard.

  1. The Wireless Power Consortium has not endorsed or approved these patent license programs. We will publish a link to any patent license program that provides a list of essential patents and royalty rates on a public website.
  2. Publication of a license program on this page is not meant to imply that the WPC advices manufacturers of Qi products to sign these license agreements.
  3. The Wireless Power Consortium has not verified that the royalty rates published by these companies comply with RAND licensing obligations.
  4. The Wireless Power Consortium has not verified that the patents on these lists are infringed by products that implement the Qi standard.
  5. The Wireless Power Consortium has not investigated the validity of the patents on these lists.

Understanding “fully-compliant subsystem”

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.

See clause 2.4 of the Logo Trademark License Agreement for full details.

Logo display guidelines

The Wireless Power Logo must always be used according to the Qi Logo Display Guidelines. Any and all user-created additions, deletions or modifications to any part of Qi logo and its additions are strictly forbidden.
