This is a list of patents (Attachment 1) in the EV Charging Patent Portfolio License (updated October 1, 2025).
Licensors agree to include all EV Charging Essential Patents that they and their Affiliates presently or in the future have the right to license or sublicense.
What does the EV Charging Patent Portfolio License cover?
The EV Charging Patent Portfolio License provides coverage for the EV Charging Standard to the extent posted here.
Who are the essential patent holders ("Licensors") to the EV Charging Patent Portfolio License?
What are the obligations of the Licensors with regard to their EV Charging Essential Patents?
Each Licensor is under an obligation to grant to Via LA a worldwide, nonexclusive license under all EV Charging Essential Patents that it and its Affiliates presently or in the future has the right to license or sublicense, enabling Via LA to grant worldwide, nonexclusive sublicenses under terms of the EV Charging Patent Portfolio License.
What is the effect on Licensees when new patents are added to the EV Charging Patent Portfolio License?
The royalties payable under the License do not increase or decrease because of an increase or decrease in the number of EV Charging Essential Patents or because of an increase or decrease in the prices of a Licensee’s EV Charging Royalty Products. Rather, they are the value of a license granted under the Patent Portfolio taking into consideration the commercial intention of the Licensors to facilitate adoption of the EV Charging Standard and make available a pool license in which royalties are the same whether one or more patents is used. New Licensors and new patents are added at no additional cost during the current Term of the License.
Are all EV Charging essential patents included?
While Licensors are under an obligation to grant to Via LA a worldwide, nonexclusive license under all EV Charging Essential Patents that it and its Affiliates presently or in the future has the right to license or sublicense, enabling Via LA to grant worldwide, nonexclusive sublicenses under terms of the EV Charging Patent Portfolio License, no assurance is or can be made that the License includes every essential patent. The purpose of the License is to offer a convenient licensing alternative to everyone on the same terms and to include as much essential intellectual property as possible for their convenience; however, participation in the License is voluntary on the part of essential patent holders.
How may a patent holder become a Licensor to the EV Charging Patent Portfolio License?
Any party that believes it has patents which are essential to the EV Charging Standard, and wishes to participate in the EV Charging Patent Portfolio License upon successful evaluation, is invited to submit them for evaluation and inclusion. Please contact Via LA at ProgramManagement@via-la.com to request a copy of the submission procedures and the terms and conditions governing the submission of patents for essentiality determination in order to join the HEVC Licensing Program.
How many licenses does an EV Charging user need?
It is up to each user to determine its own licensing needs and how it wishes to meet them. The EV Charging Patent Portfolio License is provided for a user’s convenience in acquiring patent rights necessary for the EV Charging Standard from multiple essential patent holders in a single transaction as an alternative to negotiating separate license agreements with individual Licensors. Users are free to negotiate directly with one or more Licensors for a separate license under one or more Essential Patents under independently negotiated terms, however. In addition, as discussed above, users who take Via LA’s license may have to negotiate licenses for essential patents that are not included. A license also may be necessary for other important patents (that are not essential to the EV Charging Standard).
How is the EV Charging Patent Portfolio License organized?

What are the royalties for the EV Charging Patent Portfolio License?
Royalties apply as defined in the License. Click here for information.
Are royalties due if a substantial portion of the components of product originates from a country with patent coverage but and the last step of manufacture of the final product is was completed in a country with no patent coverage?
It is common for certain jurisdictions to provide tax incentives to companies if they complete the final assembly of a product locally (e.g., “knockdown kits”). Royalties are still due, however, either because the large majority of manufacturing or final use of the product still occurs in a jurisdiction(s) where there is significant patent coverage.
