The Qi customary, established by the Wi-fi Energy Consortium (WPC), has grow to be a vital expertise in wi-fi charging. It’s a universally recognised customary that permits energy switch between gadgets with out the necessity for bodily connectors or cables. It simplifies and improves the charging expertise by eliminating the potential of tangled cables and gives a seamless and environment friendly method to energy digital gadgets. This not solely enhances person comfort but in addition contributes to a clutter-free atmosphere. The Qi customary has been broadly adopted in varied digital gadgets, from smartphones and smartwatches to furnishings and autos which have built-in charging capabilities.
In 2022, the worldwide wi-fi charging market was valued at US$22.17 billion, with an anticipated compound annual development fee of 25.8% between 2023 and 2030. As of the tip of 2023, the WPC licensed over 9,000 Qi merchandise, together with smartphones, automotive chargers, wi-fi charging pads and LED gadgets, and was anticipated to report 1 billion Qi-compliant merchandise bought.
Licensing Qi SEPs
The widespread adoption of Qi makes it a profitable marketplace for SEP homeowners, as these SEPs have to be licensed by any implementer of the usual. In January 2020, the Through LA patent pool administrator introduced a licence for patents important to the Qi customary, offering a one-stop entry level for wi-fi charging and energy switch. The pool has attracted most of the largest Qi SEP homeowners, together with:
- Canon;
- ConvenientPower;
- GE;
- Hyundai Mobis;
- Intel;
- Philips;
- LG Innotek;
- Panasonic;
- Robert Bosch;
- Siemens; and
- WiTricity.
All Through LA pool members have printed lists of Qi-standard SEPs, and these SEP homeowners commit – below the patent pool licence contract – to license all SEPs for an aggregated pool fee of between US$0.20 and US$0.85 per Qi standard-compliant product (ie, receivers and transmitters). With the anticipated one billion Qi-compliant gadgets bought in 2023, the entire SEP royalty market worth as of final yr is estimated to be between US$200 million and US$850 million when solely contemplating Through LA SEP licensors. Since not all Qi SEP holders are members of the patent pool, the entire royalty market is predicted to be past the $US1-billion mark.
For the Through LA pool, patents are pre-screened for essentiality by impartial patent reviewers. Pool members have publicly shared their verified Qi SEPs and Powermat has additionally publicly declared its Qi patents. Nevertheless, there is no such thing as a public patent declaration database. Analysing the Qi patent panorama, it’s estimated that Through LA pool members symbolize round 26-36% of the entire stack of all Qi patents (relying on the info refinement). This may imply that 64-74% of Qi patents are exterior of the pool – and these portfolios are usually not public. This creates challenges for each Qi patent licensors and patent swimming pools in addition to Qi-standard implementers.
To establish Qi-related patents, IPlytics utilised LexisNexis’s Cipher machine-learning algorithm, which makes use of true-positive examples (eg, pooled patents) and true-negative examples of non-Qi-related patents as coaching information to construct a expertise panorama. From this broad view of the Qi patent sphere, random samples of patents had been offered to subject-matter consultants to verify the Qi patents and establish others that haven’t any relation to the Qi customary. These new examples of true-positive and true-negative patents are then once more used as coaching information – an iterative method to making a complete overview of the Qi-related patent area. Nevertheless, it ought to be famous that this Qi patent panorama consists of each verified SEPs and non-SEPs (ie, patents associated to the Qi expertise however that aren’t important to the Qi-standard implementation).
As of 31 January 2024, the Qi-related patent panorama included 3,557 energetic and worldwide-granted patent households.
Counting patent households by yr of first patent publication exhibits that the cumulative variety of Qi-standard patent households has quickly elevated over the previous 10 years by greater than issue 17 (see Determine 1).

Desk 1 illustrates the highest Qi-standard patent homeowners – sorted by the variety of Qi patent households (utilizing the INPADOC patent household definition) – the place not less than one household counterpart was granted and energetic in not less than one jurisdiction. It’s value noting that six of the highest 12 patent homeowners in Desk 1 are licensors to the Through LA Qi pool.

Trying on the Qi expertise panorama gives a place to begin for each SEP licensors and licensees to enter a business dialogue about Qi patent portfolios. The SEP royalty market is profitable and sharply growing; with one billion Qi merchandise bought final yr, the marketplace for licensing these SEPs appears to have enormous royalty revenue potential – however SEP licensing for the Qi customary appears to be in its infancy. It seems that SEP homeowners are nonetheless ready and observing the market to make sure wider adoption of Qi. With the discharge of Qi 2.0 and its anticipated enhance in product adoption, the utilization of wi-fi charging is more likely to develop. This might set off the Qi SEP licensing market to lastly take off within the subsequent yr or two.
Unlocking worth by way of actionable patent insights
Qi-standard SEP licensors
Whereas solely 26-36% of Qi patents are publicly disclosed, a complete Qi patent panorama is important for profitable SEP licensing. The IPlytics evaluation of this area reveals an perception into associated patents that aren’t publicly listed.
This permits portfolio managers to:
- establish strengths and weaknesses of their portfolio;
- benchmark in opposition to rivals; and
- make knowledgeable selections on portfolio improvement.
Licensing departments would possibly use this info to:
- filter out irrelevant patents in portfolios;
- focus sources on priceless, licensable patents; and
- monitor market and possession modifications.
With over 9,000 Qi-compliant merchandise, the royalty potential is substantial, so Qi patent homeowners ought to actively monetise their portfolios.
Qi-standard SEP licensees
Qi-compliant product producers ought to put together for patent holders and swimming pools to begin searching for royalties quickly. Analysing the Qi patent panorama is a vital first step in getting ready for FRAND licensing negotiations. Mapping out the numerators and denominators allows the willpower of particular person patent holders’ and swimming pools’ share of all related Qi patents. With this information, producers can examine licensing affords and assess the relative worth of various patent portfolios. Monitoring patent filings and possession tendencies additionally helps to quantify dangers and forecast future royalty bills. This consists of monitoring exercise from patent assertion entities which can be buying Qi patents.
The highway forward
It’s anticipated that the Qi-standard expertise will grow to be one of the essential requirements to allow cordless charging – not just for smartphones and tablets, but in addition in automobiles, places of work or any floor the place customers may place their gadgets. The Qi customary is topic to an growing variety of patents that have to be licensed when merchandise come to implement the expertise, and IP professionals and patent licensing executives ought to bear some key issues in thoughts.
- Future applied sciences will more and more depend on patented expertise requirements, such because the Qi customary.
- IP professionals should contemplate working with Qi patent information as a place to begin to know the entire stack of Qi patents and the share of the patent homeowners’ portfolios.
- IP decisionmakers ought to contemplate dynamic market modifications, the place patent assertion entities usually purchase portfolios to say in depth royalty funds.
- IP professionals have to be conscious that whereas the marketplace for wireless-charging requirements is pretty new, it’s now time to assume proactively about what companies will want in two, 5 and 10 years’ time – in addition to what patent portfolios might want to assist them – in order to not get left behind.
