IPR Policy

Intellectual Property Rights (IPR) Policy v. 1.3 – effective 3 July 2018

CAB Forum Agreement for IPR Policy v.1.3

The CA/Browser Forum’s IPR Policy governs Contributions by members of the Forum during the drafting and adoption process of Normative Requirements by a Working Group. A Contribution is any material “made verbally or in a tangible form of expression (including in electronic media) which is provided by a Participant in the process of developing a Draft Guideline for the purpose of incorporating such material into a Draft Guideline or a Final Guideline or Final Maintenance Guideline.” The term “Draft Guideline” includes ballots that are being considered for adoption by a Working Group as either a “Final Guideline” or a “Final Maintenance Guideline”.

When a ballot to amend an existing Final Guideline is adopted by a Working Group, that amendment is considered a Final Maintenance Guideline, and each of the above guideline documents, as amended, is then considered a “Final Guideline” of the CA/Browser Forum.

Each of the following documents is considered a “Final Guideline”:

EV TLS Certificate Guidelines

TLS Baseline Requirements

Network and Certificate System Security Requirements

Code Signing Baseline Requirements

S/MIME Baseline Requirements
