# TREZOR REFERENCE SOURCE LICENSE (T-RSL)
|
||||
|
||||
This license governs use of the accompanying software. If you use the software,
|
||||
you accept this license. If you do not accept the license, do not use the
|
||||
software.
|
||||
|
||||
## 1. Definitions
|
||||
|
||||
The terms "reproduce," "reproduction" and "distribution" have the same meaning
|
||||
here as under U.S. copyright law.
|
||||
|
||||
"You" means the licensee of the software.
|
||||
|
||||
"Your company" means the company you worked for when you downloaded the
|
||||
software.
|
||||
|
||||
"Reference use" means use of the software within your company as a reference,
|
||||
in read only form, for the sole purposes of debugging your products,
|
||||
maintaining your products, or enhancing the interoperability of your products
|
||||
with the software, and specifically excludes the right to distribute the
|
||||
software outside of your company.
|
||||
|
||||
"Licensed patents" means any Licensor patent claims which read directly on the
|
||||
software as distributed by the Licensor under this license.
|
||||
|
||||
## 2. Grant of Rights
|
||||
|
||||
(A) Copyright Grant - Subject to the terms of this license, the Licensor grants
|
||||
you a non-transferable, non-exclusive, worldwide, royalty-free copyright
|
||||
license to reproduce the software for reference use.
|
||||
|
||||
(B) Patent Grant - Subject to the terms of this license, the Licensor grants

||||
(A) No Trademark License - This license does not grant you any rights to use
|
||||
the Licensor's name, logo, or trademarks.
|
||||
|
||||
(B) If you begin patent litigation against the Licensor over patents that you
|
||||
think may apply to the software (including a cross-claim or counterclaim in
|
||||
a lawsuit), your license to the software ends automatically.
|
||||
|
||||
(C) The software is licensed "as-is." You bear the risk of using it. The
|
||||
Licensor gives no express warranties, guarantees or conditions. You may have
|
||||
additional consumer rights under your local laws which this license cannot
