As a condition to the grant of rights to Licensee to make, sell, offer for
sale, import or distribute an Implementation under Section 1.1, Licensee must
make its Necessary Claims available under this License, and must reproduce
this License with any Implementation as follows:

a. For distribution in source code, by including this License in the root
directory of the source code with its Implementation.

b. For distribution in any other form (including binary, object form, and/or

If any Licensee, its Affiliates, or its agents initiates patent litigation or
files, maintains, or voluntarily participates in a lawsuit against another
entity or any person asserting that any Implementation infringes Necessary
Claims, any patent licenses granted under this License directly to the
Licensee are immediately terminated as of the date of the initiation of action
unless 1) that suit was in response to a corresponding suit regarding an
Implementation first brought against an initiating entity, or 2) that suit
was brought to enforce the terms of this License (including intervention in a
third-party action by a Licensee).
